Lost 5/6g Wifi after updating OpenWRT

JustMashingKeys · September 13, 2024, 11:46pm

After updating OpenWRT on my Bananapi R4 with an AW7916-NPD wifi card a few days ago (which I generally do at least once every couple weeks) I no longer have my 5g/6g bands. The wireless config still all looks right, LuCi shows them broadcasting but shows 91dbm and "No client associated" for both bands and the bands aren't actually showing up on any device or wifi-scanning app. The blob from before and after updating only has two differences:

MT-7916e is gone (but the MT7916/MT7915 drivers/firmware still show
wpad-basic-mbedtls is gone (it was not actually installed, instead I use OpenSSL, it was just listed, it was a bug).

LSmod:

lsmod | grep mt7996
cfg80211              311296  5 mt7996e,mt7915e,mt76_connac_lib,mt76,mac80211
mac80211              602112  4 mt7996e,mt7915e,mt76_connac_lib,mt76
mt76                   69632  3 mt7996e,mt7915e,mt76_connac_lib
mt76_connac_lib        49152  2 mt7996e,mt7915e
mt7996e               118784  0

I'm not sure what else might be helpful/needed, but happy to provide anything needed to help troubleshoot this. I don't really want to start over and can't revert as soon I'm installing a new WiFi card (the BE14 WiFi 7 card) and need the latest (well 2nd latest now I believe) snapshot for the drivers but would like my 5/6g bands back until I can find the time to put the new card in and print the new case to fit it.

@Ansuel mentioned on irc: "it looks like there was a backport for mtk packages and the wifi package got split in 2 package, one for the driver and one for the firmware. On updating to the new stable release user have wifi broken as the firmware package is not installed".

Try opkg install kmod-mt7996-firmware and see if that does anything...

JustMashingKeys · September 16, 2024, 7:28pm

No luck, says it's already installed and up to date.

Unfortunately no change. It seems it's in the latest (.51) kernel as it required me to update to that to install it, then showed it installed after the update.

JustMashingKeys · September 21, 2024, 4:39am

Sorry to bump this but still haven't figured it out, anyone have a direction to point me or is there any other info I should post that might shine a light on the problem? I tried doing a restore to a backup I had from 3 weeks ago prior to this, no errors but it also seems to not take, kernel stays the same and no change to functionality.
