This happened on OpenWrt SNAPSHOT r13520-68b94f0fb4, but it’s pretty random. I haven’t been able to figure out what causes it. It usually happens at least once within a week. I’m not sure why there’s no call stack here, I also tried `cat /sys/kernel/debug/crashlog` a few hours after it happened and got a “No such file or directory”.

Supply the following if possible:
- Device problem occurs on: ZBT 3526-16MB + 32 MB - Software versions of OpenWrt/LEDE: current trunk (kernel 5.4)
- Steps to reproduce: when i update the firmware, i see that there is a network after reboot for ~10sec, and then it is gone, and is not accessable, seeems to be, that something is crashing.
i can only hard-reset - nothing else.

any idea ?
maybe it is related also like the other bugs reported ? for bootloop or hanging/crashing mt7621 ?

- Device problem occurs on - x86
- Software versions of OpenWrt/LEDE release, packages, etc. - 19.07.3

I think it’s a bug/overlooked use case, but when you have interfaces bridged in the UCI config, the MTU setting does not get applied to the member interfaces (physical or VLAN).

config interface 'lan'
        option proto 'static'
        option netmask '255.255.255.0'
        option ip6assign '60'
        option ipaddr '192.168.1.1'
        option type 'bridge'
        option mtu '9000'
        option ifname 'eth1 eth4.10'

When I boot using this config I have connectivity issues with devices using Jumbo frames. ifconfig confirms that MTUs on the members interfaces are still at default 1500.

I have to manually use the ifconfig tool to set the MTU (i.e. ifconfig eth4.10 mtu 9000) to get the network back up and running correctly.

Obviously these commands could be scritped, however it was my understanding the UCI network config should be doing this .

On my Lantiq-XRX200 device Fritzbox 7360 SL, the WIFI PHy doesnt gets detected anymore. right after 1 second when booting the device. i get a kernel warning that the “PCIe PHY cant get detected and right after that 5 lines of
“PCIe phy_link_up timeout”

This happend in release of 19.07.x and trunk.

[ 0.864077] ifx_pcie_wait_phy_link_up timeout
[ 1.081343] ifx_pcie_wait_phy_link_up timeout

Try to compile umdns with gcc10 and it will break with following error:

USB controller “f10f8000.usb3” is preventing UAS from working on OpenWRT devices, as dmesg states:

[ 1.830001] usb 3-1: new SuperSpeed USB device number 2 using xhci-hcd
[ 1.860632] usb 3-1: USB controller f10f8000.usb3 does not support streams, which are required by the UAS driver.
[ 1.870949] usb 3-1: Please try an other USB controller if you wish to use UAS.
[ 1.878291] usb-storage 3-1:1.0: USB Mass Storage device detected

Checked in OpenWRT 18.04 and 19.03 with Linksys WRT3200ACM and Turris Omnia. This impacts USB3.0 speeds.

To reproduce just hook up a USB3.0 HDD to a OpenWRT device on the USB3.0 port and see dmesg.

Is it possible to try another controller or fix f10f8000.usb3?

- Device: Raspberry Pi4
- Snapshot kernel 5.4 with 5.7 backport
- Install ath9k_htc dongle and connect WiFi client

So, I have been able to tackle down who is causing a kernel panic and reboot of my RPi4 with current snapshots.

It is the ath9k_htc dongle I use but only if there are clients connected to it
Apparently it corrupts memory so the kernel panic look quite different among them, here two caputer with serial:

I have tried two different RPi4 hardware and two different SD cards. No other devices are connected to the USB ports,ath9k_htc dongle is connected to USB 2.0 port.

With 19.07.x on a Orangepi PC2 device, the same dongle behaved correctly

Supply the following if possible:
- Device problem occurs on: Z83II mini pc. https://www.minipcdb.com/articles/Meet-Z83II-Mini-PC - Software versions of OpenWrt/LEDE release, packages, etc. Tested on both 19.07.3 and latest snapshots, both failed.
- Steps to reproduce: Write to image to the embedded emmc disk and boot it.

I’ve tested both 19.07.3 and latest snapshots build of openwrt x86-64 build on the Intel Z8350 fanless mini PC. Both failed to boot. The kernel can boot up correctly, but the system hang at waiting for root device. If the image is burned on USB disk, it can boot up correctly without any issue.

I searched on Google and found this post - https://forum.archive.openwrt.org/viewtopic.php?id=72195

I did the test on 19.07.3 and verified the system can boot up correctly from embedded emmc storage that by adding the following two options into the target/linux/x86/64/config-default file
CONFIG_MMC_SDHCI_ACPI
CONFIG_X86_INTEL_LPSS

Could you approve to add the options into the future update to support booting from emmc storage?
Thanks!

It seems that recent snapshots broke vlan isolation, I guess https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=9da2b567605b0964d921b9ca4f0c9886db4f636d should be responsible.

I tried to upgrade the kernel to 5.4.56, which did not solve the problem.Please help me

Latest snapshot OpenWrt

It can be reproduced on many platform, you can just verify with Virtualbox and x86 images.

First restore to factory, then set ‘option nonwildcard=0’, reboot, ssh to OpenWrt, run ‘nslookup he.net’, you will get ‘;; connection timed out; no servers could be reached’ error, manually restarting dnsmasq service or setting ‘option localservice=0’ could fix it.

- I’ve personally tested it on ZyXEL NBG6817
- Any version with https://patchwork.kernel.org/patch/11283121/ patch applied
- To reproduce:
# ifdown wan
# ifconfig (wan_interface) MTU 1499 (or 1501 or anything other than 1500)

This bug is caused by txfifosz being 0 on IPQ806x devices (and possibly more) unless tx-fifo-depth is specified in device tree, potential fix would be to specify tx-fifo-depth in device tree for all affected devices, or, check if txfifosz == 0 and then allow MTU change.

Supply the following if possible:
- Device problem occurs on
- Software versions of OpenWrt/LEDE release, packages, etc.
- Steps to reproduce

This problem is occurring on a BT HomeHub 5A. I have two of these and the problem happens on both of them. I am currently using V5.X and the issue is only here but it is working in v19.07.3.

The issue is that I am not able to auto-mount my NTFS drive with bootup through fstab.
The error is as follows:

Although I can mount the drive manually through ntfs-3g and the package is already installed but somehow the system thinks it is not available. For now the workaround is to manually mount the drive when the boot ends.

Please fix this issue thanks.

The initramfs-kernel.bin image for the ath79/mikrotik mikrotik,routerboard-sxt-5nd-r2 device (SXT Lite 5) is missing the nand-utils package. Therefore, when booting via TFTP (e.g., to install OpenWrt for the first time), the sysupgrade image can not be flashed:

so the device can’t boot, as nothing has been written to NAND.

Device: Ubiquiti Routerstation (ar71xx)
Software: OpenWrt SNAPSHOT, r14382+7-ad0f0df909 (local compilation after Sep 3 2020 git pull)
Symptoms: commands like ‘wifi up wlan1’ on a system with wlan0, wlan1, and wlan2 (phy0,1,2) , make other wlanN disapperar than wlan1.
plus in dmesg messages like
[ n.n] do_page_fault(): sending SIGSEGV to hostapd for invalid write access to 00000000
[ n.n] epc = 77e79e6c in libc.so[77e4c000+9c000]
[ n.s] ra = 77e1e309 in libubus.so[77e1c000+13000]

Bug found through experimentation:
script: /lib/netifd/wireless/mac80211.sh
function: drv_mac80211_teardown()
line: json_select data
problem: ‘data’ does not produce phy, ‘config’ does.
corrected line: json_select config

Going though experimentations also found that there may be problems in
script: /lib/netifd/hostapd.sh
function: wpa_supplicant_run()
line: ubus call wpa_supplicant config_add
and the lines that follow with parameters and line continuations.
Replaced:

ubus call wpa_supplicant config_add "{ \
	\"driver\": \"${_w_driver:-wext}\", \"ctrl\": \"$_rpath\", \
	\"iface\": \"$ifname\", \"config\": \"$_config\" \
	${network_bridge:+, \"bridge\": \"$network_bridge\"} \
	${hostapd_ctrl:+, \"hostapd_ctrl\": \"$hostapd_ctrl\"} \
	}"

By:

local br=${network_bridge:+',"bridge":"'$network_bridge'"'}
local hc=${hostapd_ctrl:+',"hostapd_ctrl":"'$hostapd_ctrl'"'}
local jsonstr='{"driver":"'${_w_driver:-wext}'","iface":"'${ifname}'"'${br}${hc}',"ctrl":"'${_rpath}'","config":"'${_config}'"}'
ubus call wpa_supplicant config_add ${jsonstr}

because in a separate test script just to see the workings of the original I could not get it to work due to the nested parameter substitution.
Have removed all the \” as the " do not need to be escaped when within single quotes.

I am using default build of OpenWRT 19.07.4 for TL-WR841N v13 without any additional packages. I have Ethernet PPPoE from provider, some ethernet and WiFi WPA2 clients. WiFi and Ethernet are unstable: they can disappear for 30-60 seconds without any serious reason. On 18.06.8 there wasn’t those problems. I attached system log. Thanks for help.

Hi,

I am using the following with the latest update of openwrt:

Model Netgear R6220
Architecture MediaTek MT7621 ver:1 eco:3
Firmware Version OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.260.30581-915a64c
Kernel Version 4.14.195

The problem occured already with 19.07.3 several times, so I upgraded to 19.07.4, but the problem remains.
The wifi module kept crashing and in consequence a part of the wifi devices cannot connect anymore. Sometimes the router
recovers by itself, sometimes not and a reboot is necessary to get wifi working again. It mostly affects the 2,4 GHz band
and not the 5 GHz band, but that might be related which device is renewing DHCP or which ones are not (I am not sure).
A reboot solves the problem, but after some time, the problem occurs again. After the below warning, the router runs without
further problems for 2 days now. So it seems pretty rare. Nevertheless, the same hardware was working fine with 18.x
openwrt for a year at least. No kernel warning at the time. I cannot completely rule out that the HW is broken as it is
of age, as you can see. Any hint on what I should report or test myself is welcome! I can help debug and even install
updates that should fix the problem, if necessary. The router ist just used as an access point - routing is taking
place elsewhere.

Here is the korresponding kernel warning, where I included the immediate log entries before and after:

With latest uhttpd package (2020-09-18), the wireless scan failed in our MT7688 devices (ramps mt76x8). The original uhttpd (2020-08-05-212f8364) version works before.

The iwinfo.scan is using the nobatch=true flag when calling rpc.declare (luci/modules/luci-base/htdocs/luci-static/resources/network.js:83)

Enabling this option makes the ipv6 connection unstable.

Example: connecting to #openwrt-devel from hexchat (Ubuntu) makes you constantly disconnect.
Disabling flow offload makes the connection stable.

Hi,

in the current trunk version, Broadcom Roboswitch will not work for certain router models. However, in the past it did work.

Building OpenWrt from scratch results in a working switch with v17.01.5 (from 15 Jul 2018 21:25:16) for target profile “Broadcom SOC, BCM43xx Wifi (brcmsmac)”. Building OpenWrt from scratch for v18.06.0 (from 30 Jul 2018 18:44:34) results in the switch not working for the same target. So the problematic commit must have been between 15 Jul 2018 and 30 Jul 2018, and the problem is still present today.

For v17.01.5

# dmesg | grep switch

[    3.683106] b53_common: found switch: BCM5325, rev 4

Despite the message “Roboswitch not implemented” the switch comes up automatically and I can ping other computers connected through the switch.

For v18.06.0

The switch does not come up and thus I cannot ping.

I tested this for the (unsuported) router Huawei B593u-12. You can find details about the router, logs, etc. under https://openwrt.org/toh/huawei/b593u-12

This also seems to address other routers, e.g. ZTE H218N, see https://forum.openwrt.org/t/b53-failed-to-detect-switch-on-bcm5358/20011

Hello all,

For some time I see that a problem persists when you want to change the ip address to access the router, this cannot be done from the luci web interface.
The following errors occurred after I connected to the web interface and I wanted to access 5ghz wifi from the phone it can no longer connect to wifi.

Hi,

I’m building image for my Xiaomi Redmi 2100 using the imagebuilder, but when I flash my router it never comes back and the amber LED is on. I’m building my image this way:
make image PROFILE=xiaomi_redmi-router-ac2100 PACKAGES=”luci -luci-proto-ppp wpad-wolfssl iperf3 ethtool mtr iwinfo kmod-tcp-bbr kmod-mtd-rw libustream-wolfssl ca-bundle -ppp -ppp-mod-pppoe -kmod-pppox -kmod-pppoe -kmod-ppp -wpad-basic-wolfssl” I’m using GitHub actions to automate it, you can check the workflow here: https://github.com/amaumene/xiaomi_redmi-router-ac2100_openwrt_mesh/blob/master/.github/workflows/build-openwrt.yml I’ve restored the original firmware and flashed with the latest snapshot from openwrt.org without any issue. The only error that I can see is this “/home/alex/openwrt-imagebuilder-ramips-mt7621.Linux-x86_64/build_dir/target-mipsel_24kc_musl/root-ramips/lib/functions/procd.sh: line 43: /home/alex/openwrt-imagebuilder-ramips-mt7621.Linux-x86_64/build_dir/target-mipsel_24kc_musl/root-ramips/usr/share/libubox/jshn.sh: No such file or directory”

Flashing the TL-WR810N v1.1 (EU version) with target ath79 is known to cause soft brick. Appears to work with ar71xx target.

There is a warning about this already on the device page: https://openwrt.org/toh/tp-link/tl-wr810n

Problem detailed in forum post:

https://forum.openwrt.org/t/tp-link-tl-wr810n-v1-ath79/48267

I could not find a record of this in the bug tracker, and so I have created one.

- Device problem occurs on
D-Link DIR-645 Rev. A1

- Software versions of OpenWrt/LEDE release, packages, etc.
LEDE 19.07.4

- Steps to reproduce
Setup the wireless connection. After some time the WLAN connection stops working. A restart is necessary to regain WLAN.

Topic is discussed in the forums:
https://forum.lede-project.org/t/d-link-dir-645-wifi-interface-not-maintaining-connection/6277

I am able and willing to provide log files. But I am new to the business of debugging itself. Help and guidance welcome!

  Repository UUID: 48f6a8c1-d3d8-b121-14bd-ce57b7db7bff
  Revision: 92580

- Steps to reproduce

 1. add wifi client
 2. add relay bridge interface between wlan and lan
 3. the wlan interface get ip 192.168.3.136, the pc in lan get ip 192.168.3.128, the ip of root ap was 192.168.3.1
 4. the pc can ping 192.168.3.1 but can not ping 192.168.3.136

After connecting RTL8811AU to USB, it turns out that OpenWRT cannot handle it. Please add the driver to the official images.

Channels 13, 12 and auto are unusuable despite a valid CRDA selection (PL).

Lack of functional support for channels 13 & 12 where those are legally available renders OpenWrt unusable as AP/client on raspberry pi 3 & zero w. Both share the same BRCM 43430 driver.

Auto selection is also crippled:
Wed Dec 30 04:16:49 2020 daemon.warn hostapd: wlan0: IEEE 802.11 Configured channel (0) not found from the channel list of current mode (1) IEEE 802.11g
Wed Dec 30 04:16:49 2020 daemon.warn hostapd: wlan0: IEEE 802.11 Hardware does not support configured channel

Both would be a showstopper. OpenWrt on such platforms is often picked for its AP capabilities.

Applies to all versions including master branch,
but only in ath79 target
old ar71xx target does not have the problem

for the internal built-in switch for ar934x series
port 5 of the switch is missing, and therefore physical ports
that are connected to port 5 of the internal switch instead of GMAC0
cannot be used.

Attempting to set a VLAN that includes port 5 never takes effect.

This issue is not noticed for many other ar934x boards with 5 physical ports
because routers with 4 LAN and 1 WAN port use GMAC0 for the WAN port
instead of port 5 of the internal switch.

in ar71xx the driver is
target/linux/ar71xx/files/drivers/net/ethernet/atheros/ag71xx/ag71xx_ar7240.c

in ath79 the new driver is
target/linux/generic/files/drivers/net/phy/ar8216.c

for 2 of my AR9341 boards
EAP300 v2 and ENS202EXT
port 5 is missing from swconfig output

The dmesg shows a bad eraseblock 258 at 0×000002040000, this results in an unreadably factory partition. Symptoms: unreadable MAC addresses (as shown in the dmesg) and TX power on the radios limited to 6dBm, probably because of unreadable calibration data.

A hexdump of the factory partition shows correct contents, but shifted by 0×20000 bytes.

When you set the MTU of a ppp interface with proto=pppoe and ifname=nas0 via the mtu option,
the configured mtu will not be set on the ppp interface (what you want), but on the
underlying interface named by ifname (what you normally don’t want to change).

This leeds to log messages like this:

pppd[5641]: Interface nas0 has MTU of 1448 – should be at least 1500.

and MTUs other than what you really want.

example:

desired PPPoE MTU: 1448
actual nas0 MTU: 1448
actual PPPoE MTU: 1440

This issue seems to be related to the commit 7ac29b75319fd69a8a7c0aeea7804d381ec07d3d of netifd.

Actually, I am trying to stabilize wwan (3g actually; LTE later on) using pppd with my HUAWEI ME909u-521,
because either my MT7620-based router locks up during boot already; or after short period of real usage.
During night, when router is almost idle, just some watchdog date sent via wwan, no problem.

First trace of a possible problem was this msg in logread:
daemon.notice netifd: wwan (1676): Error setting WWAN mode!

Wich is expected, as in /lib/netifd/proto/3g.sh:

...

                      elif echo "$cardinfo" | grep -qi huawei; then
                              case "$service" in
                                      umts_only) CODE="14,2";;
                                      gprs_only) CODE="13,1";;
                                      *) CODE="2,2";;
                              esac
                              export MODE="AT^SYSCFG=${CODE},3FFFFFFF,2,4"    #####Will not work !!!!! Switching USB-Stick to 3g-preferred ?

...
...

                      [ -n "$MODE" ] && gcom -d "$device" -s /etc/gcom/setmode.gcom

Will not work, because the ME909u-521 rejects AT^SYSCFG . However, AT^SYSCFGEX will work, but having different syntax.
MODE=”AT^SYSCFG=${CODE},3FFFFFFF,2,4” will be effective for simpler modems.

/etc/gcom/setmode.gcom returns exit 1; but this error is not checked in 3g.sh

Not shure, whether this is the reason for my problems; however, reason of concern, as high speed modems
are more and more common.
Willing to participate in testing/debugging.

For details regarding my modem, consult
HUAWEI ME909u-521 LTE LGA Module AT Command Interface Specification

With LEDE version reboot-1444-g1bb914d, when pulling data through the WAN interface to the LAN interface at a sufficiently high speed, e.g. on a Raspberry Pi connected by ethernet to a LAN port, and the WAN interface connected to a gigabit internet service and issuing a command like:

curl https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.7.2.tar.xz > /dev/null

From the pi, I see something like:

This looks similar to: https://dev.openwrt.org/ticket/11091

Hello,

As I said, if I change the TX power from 0 dBm to 20 dBm doesn’t nothing. There isn’t any visible change in tx power. I tested other powers too (5, 8, 15,..).

It is a Xiaomi Nano (lite).

SoC Type: MediaTek MT7628AN ver:1 eco:2
MIPS: machine is MiWiFi Nano
Linux version 4.4.19 (-) (gcc version 5.4.0 (LEDE GCC 5.4.0 r1444) ) #0 Fri Aug 26 15:03:40 2016.

Some of the recent Linksys (maybe other) routers have two partitions: WRT1900, EA8500, etc.

Would be great if when running sysupgrade on those routers it did NOT kill all active processes and kept the router working while writing an image to the inactive partition.

Would also be great if there was an option to prevent automatic reboot after writing an image.

Ultimate goal is to have an upgrade process where current working state is uninterrupted and only when you reboot – you boot into new image.

I’ve run into this earlier myself and now we are seeing at least one package failing because of it.
https://github.com/openwrt/packages/pull/2823

People seem to have run into this issue before since it’s listed as a requirement for Ubuntu 64-bit as an example.
https://wiki.openwrt.org/doc/howto/buildroot.exigence#examples_of_package_installations

- Device problem occurs on:

WRT3200ACM

- Software versions of LEDE release, packages, etc.:

master tree (and v17.01), bisected to f24ffb901e0408917748773b883841eca52eea05.

- Steps to reproduce

* Flash a recent LEDE snapshot on the WRT3200ACM (and factory reset),
* enable wifi (2 or 5 Gz) → Wifi works
* disable wifi → errors in the dmesg about not being able to set a feature (can’t remember the exact error)
* re-enable wifi → errors in the dmesg saying that the adapter does not exist. This gets shouted in the dmesg every 5 seconds

A reboot doesn’t fix the issue. I need to downgrade the firmware prior to f24ffb901e0408917748773b883841eca52eea05 and factory reset to get the wifi adapters back.

For the Vlan bridge, symptoms are easier to detect:
* create a new adapter bridged on eth0.100 eth1.100
* no traffic goes through it. An snapshot before f24ffb901 used to work
(the setup is the Free french provider which has a vlan between the modem and the TV adapter over VLAN 100. So the LEDE box should act like a pass-through here only)

I bisected to the commit mentioned above (which, to me seems suspicious given that the driver is for mvsw61xx and the switch in the WRT3200ACM is MV88E6352, so a different generation). I don’t have enough knowledge of the chip to understand why this fails, but I don’t feel confident enough to simply send a PR with the revert.

Reverting f24ffb901e on top of master makes the Wifi and VLAN back to normal.

Here is one that gets a bit ugly. Lets say we chain a bunch of LEDE based routers together. Lets also enable a nice numbering system in IP4 and IP6. Lets enable DHCP-PD through the network, because our ISP was generous with a /56. The IP4 is only static and is easy to control, see table below. Its tedious, but easy. The problem is in parallel the IP6 addresses compound in the ULA region. Each router DHCP-PD the ULA above it, and gets its own ULA from Global settings in Network UCI. There seems no easy way to control this mass cascade of ULA, and get good fail over.

Ideal Requirements:
(1) If router above is unavailable, then next tier router uses ULA (network global UCI) to begin assigning addresses to clients and subnets.
(2) If router above is available, then next tier router expires its self-generated ULA and subnets, and gets ULA from delegation above to then re-delegate to subnets.
(*) Bonus: make some parts optional

One-to-one NAT means you have LAN address on interface and its mapped 1:1 to external ip addresses.
You can have incoming connections.

In such configuration “ipaddr” must be specified in 6to4 protocol section.
But due to bug this addr is submitted as local address for tunnel creation.
It does not work.

I fixed this with the following patch to /lib/netifd/proto/6to4.sh

48,53c48,53
< [ -z “$ipaddr” ] && {
< if ! network_get_ipaddr ipaddr “$wanif”; then
< proto_notify_error “$cfg” “NO_WAN_ADDRESS” < return
< fi
< }

if ! network_get_ipaddr ipladdr “$wanif”; then
> proto_notify_error “$cfg” “NO_WAN_ADDRESS”
return
> fi
>
> [ -z “$ipaddr” ] && ipaddr=$ipladdr
76c76
< json_add_string local “$ipaddr”

json_add_string local “$ipladdr”

I suggest you integrate this patch or do something similar yourself.

Dynamic vlan config on ath10k seems not to work. Same config on ath9k works fine.

Config:

config wifi-device  radio0
        option type     mac80211
        option channel  36
        option hwmode   11a
        option path     'pci0000:01/0000:01:00.0'
        option htmode   VHT80
[...]

config wifi-iface
        option device   radio0
        option network  vlan1
        option mode     ap
[...]
        option dynamic_vlan     '1'
        option 'vlan_tagged_interface' 'eth1'
        option 'vlan_bridge' 'br-vlan'
        option 'vlan_naming' '0'

When specifying

CONFIG_KERNEL_GIT_CLONE_URI

a clean build fails, as the system assumes a already downloaded/cloned/packed linux-source is present in dl/ which on a freshly checked out openwrt/lede source isn’t the case yet, when

toolchain/kernel-headers

is about to be built.

The build error looks like:

make[3]: Entering directory `/build/lede.git/toolchain/kernel-headers'
zcat /build/lede.git/dl/linux-4.4.42.tar.gz | tar -C /build/lede.git/build_dir/toolchain-arm_cortex-a9+neon_gcc-6.3.0_glibc-2.24_eabi -xf -
gzip: /build/lede.git/dl/linux-4.4.42.tar.gz: No such file or directory
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

The issue apparently is located in

include/kernel-defaults.mk

, line 53ff::

  ifeq ($(strip $(CONFIG_KERNEL_GIT_CLONE_URI)),"")
    define Kernel/Prepare/Default
        zcat $(DL_DIR)/$(LINUX_SOURCE) | $(TAR) -C $(KERNEL_BUILD_DIR) $(TAR_OPTIONS)
        $(Kernel/Patch)
        $(if $(QUILT),touch $(LINUX_DIR)/.quilt_used)
    endef
  else
    define Kernel/Prepare/Default
        zcat $(DL_DIR)/$(LINUX_SOURCE) | $(TAR) -C $(KERNEL_BUILD_DIR) $(TAR_OPTIONS)
    endef
  endif

For the package

kernel-headers

it just tries to access the not-yet downloaded/cloned/packed linux kernel source archive.

Supply the following if possible:
- Device problem occurs on BT Home Hub 5
- Software versions of LEDE release, packages, r3425-f28eef4 and previous versions
- Steps to reproduce

It can be after a few hours, if WiFi 5g radio0 Qualcomm Atheros QCA9880 802.11nac (radio0) is configured to a Band B channel, it jumps to Channel 36 even though there is no apparent interference.
This appears to happen more frequently overnight during long periods of inactivity. Whilst the device is being used it does not happen.

After it does make the jump, if I stop and restart the device (using luci disable/enable) the device stops, but it fails to restart. Attempts to change the channel and re-enable the device also do not help.

It requires a reboot to restore service.

Vlan don’t work.
