Comments
Skrity: Reporting the same happening on mir3g v1 and redmi ac2100. At the moment fixing this in local.rc like this: Both release candidates are affected, but latest 19.07 is not. |
bouzouste: Reporting also the same. Tested on both rc1 and rc2 of 21.02 Works great with older 19.07. |
Skrity: a few bootlogs if they help |
bouzouste: I just saw in source, this piece of code:
Do you believe it has something to do with this particular issue? |
mishamosher: The issue still happens on RC3. |
csharper2005: The issue still happens on 21.02.1 |
csharper2005: Other mt7621 devices are also affected: |
serj-47: I checked on my xiaomi 4a with firmware 21.02.1 stable and on a snapshot from 02/03/2022. And still the same problem. |
Still happening in 21.02.2. Haven't tried latest snapshot builds, but FS#3932 (#8930) reports 2022-02-20 snapshot as working for Mi 3G. |
fwiw, I encountered this problem yesterday with my R4AG with 21.02.2 when it is power cycled, with WAN port connected to 100mb switches. One particular unmanaged TPlink TL-SF1008D v9.1 switch was persistently failing. Other TPlink and Netgear switches were slightly better. I installed snapshot for 10 March 2022, and problem appears to be resolved (for above SF1008D) after reading FS#3932. |
Issue solved with 22.03-rc1:
|
so shall we close this? |
@Djfe yes, as well as these (they're the same issue): |
@hauke here are three issues about the same bug. It was fixed with 22.03 release candidate 1 |

Xiaomi Mi Router 4A Gigabit Edition
OpenWRT 21.02-rc2
The link speed auto-negotiation is broken. I've a 1Gbps switch and a 4-lines ethernet cable (pins 1 2 3 6). It should be possible to achieve a max speed of 100Mbps full duplex. When I connect the switch to the WAN port of the router, the link speed shows up as 1Gbps full duplex (in the router).
Ethernet connectivity remains non-functional unless I set a proper speed and duplex (ex.
ethtool -s wan speed 100 duplex full autoneg off
