I have this Archer C50 V4.2
tested all available versions of openwrt for V4 installed it but could not manage to start 2.4 wifi
simply 2.4 signal is not seen on signal analyzer,
i opened the casing of it and took pictures of the chips,
MEDIATEK MT7628AN 2031-AFSL BCMS7JGP
MEDIATEK MT7612EN 2031-BMJL ETPSUU75
so , from the archer-c50 page on openwrt i can say it is same as v3 in soc
but in the WLAN hardware MediaTek MT7628AN, MediaTek MT7612EN
so it is some how combination between v3 and v1 in WLAN hardware..
can this be added to the Hardware list and made firmware for it ?
hardware is the same as C50 v4 that is already supported
are you sure you did not make any mistakes?
follow directions from commit message
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=01dcd574a24864c10a9c4df4304a3ce0da5c11a9
I installed [Stable Release builds] and latest [Development Snapshot builds]
both did not manage to turn 2.4 Wi-Fi to broadcast signal. 5G seems to work fine.
is there a possibility that this could be a hardware malfunction on this device ?? and how do i know? I mean if there is a way that i can make sure of it by executing commands via ssh or see some logs
yes you can post kernel log here
