Same here with a build from openwrt-18.06 wrt 5GHz radios, but the 2.4GHz radio somewhat works, very very slowly. I can't switch the 5GHz radios to AC mode no matter what I try (I previously opened FS#535, same router, I'm using US country code).

adityaxavier:

Can you check this configuration, this is working perfectly for me.

config wifi-iface
option device 'radio2'
option network 'lan'
option mode 'ap'
option ssid 'Wifi5G1'
option key 'password'
option encryption 'psk2'


manusfreedom:

Not better.
I reset the wifi config using:
rm -f /etc/config/wireless
wifi config
What I got in config
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path '18000000.axi/bcma0:7/pci0000:00/0000:00:00.0/0000:01:00.0'
option htmode 'HT20'
option disabled '1'

config wifi-iface 'default_radio2'
option device 'radio2'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'none'

So, unable to detect correctly wifi 5G (11a not 11g)

manusfreedom:

And below with the previous update (2018-06-07):

config wifi-device 'radio0'
option type 'mac80211'
option channel '36'
option hwmode '11a'
option path '18000000.axi/bcma0:7/pci0000:00/0000:00:00.0/0000:01:00.0'
option htmode 'VHT80'
option disabled '1'

config wifi-iface 'default_radio2'
option device 'radio2'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'none'


adityaxavier:

Can you try doing a firstboot and copy paste my configuration ? Because there are few issues with your configuration...

1. Radio0 is supposed to be a higher band 5G network, i.e 147+
2. From some time in trunk releases, recreating the wifi config puts the Channel as Auto.. so am not sure whats happening.

Please try the RC1 release as thats what am running right now.

manusfreedom:

I confirm no problem with RC1.

I am compiling last trunk to test.

rfr:

Yes, same here, going back to v18.06.0-rc1 fixes it.

Probably something wrong with the round of v4.17/v4.18 brcmfmac backports that went in just after RC1?

adityaxavier:

I agree.. 18.06.0-rc2 has problems with Wifi 5G.

18.06.0-rc1 has all three (2G + 5G) wifi working.

18.06.0-rc2 only has 2G wifi working. 5G is listed as only capable of Legacy / N in luci. Using the same configuration as 18.06.0-rc1 doesn't have 5G wifi working.

andy-vdg:

Can confirm the same with 18.06.0-rc2. Tried to flash my Nighthawk X6 R8000 last night and could only select Legacy / N in luci. Downgraded to 18.06.0-rc1 which had the same problem. Not sure how others here seem to have gotten RC1 working. I flashed with erasing configuration.
Downgraded further to 17.01.4 which works fine.
Could be related to task_id=1665

rmilecki:

This is a regression caused by the commit 2811c97 ("mac80211: backport brcmfmac firmware & clm_blob loading rework").

rmilecki:

Fix sent for the wireless-drivers-next git tree:
[[https://patchwork.kernel.org/patch/10539435/|[PATCH] brcmfmac: fix regression in parsing NVRAM for multiple devices]]

manusfreedom:

I am compiling trunk with this change:
package/kernel/mac80211/patches/327-v4.17-0008-brcmfmac-introduce-brcmf_fw_alloc_request-function.patch
########################## Line 133 (add the + 1)
fwreq->domain_nr = pci_domain_nr(devinfo->pdev->bus) + 1;
##########################

To confirm or not.

manusfreedom:

I confirm it works with last trunk version and the "+ 1".
