I recently flashed a Netgear R6120 with OpenWrt, and have got almost everything working (lan, wan). The only thing is that I can enable my wifi network, but my devices cannot find it. Hide SSID is turned off, and power output/distance to device do not affect this. After removing and adding the wireless device, I once briefly saw the OpenWrt network, but only once. Also, the device seems to hang if I change the power output. Is there anything known about the R6120 being buggy with OpenWrt? I can't find anything on the forums related to my problem, and the R6120 seems like a relatively new device. I have also flashed the sysupgrade to the device, this did not fix the problem either.
What does dmesg
or logread
say? That should provide some clues.

A little more digging (post from November 2017):
The R6120 has a MediaTek MT7628A, quite possibly the issue.
https://wireless.wiki.kernel.org/en/users/drivers/mediatek
https://wikidevi.com/wiki/Mt76
Correction:
WLAN Hardware
MediaTek MT7628A, MediaTek MT7612E
Rereading the MT76 post I see:
7620/7628/7610/7612/7603/7615 will be added soon.
so perhaps I am wrong.
This might be it, though I don't know the cause of the error:
Thu Nov 1 10:15:28 2018 user.notice mac80211: Failed command: iw phy phy1 set antenna all all
Thu Nov 1 10:15:28 2018 user.notice mac80211: Failed command: iw phy phy0 set antenna all all
Reading documentation I see failed antenna commands may be the case because radios are already up. Also, according to openwrt shell, command should be
iw phy phy1 set antenna all
After:
wifi down
root@OpenWrt:~# iw phy phy0 set antenna all
command failed: Not supported (-122)
root@OpenWrt:~#
I can confirm that at least with "OpenWrt SNAPSHOT r9355-94993a7" for the r6120 everything is working very well now ...
not sure if that did the trick: http://lists.openwrt.org/pipermail/openwrt-devel/2019-February/015687.html
Confirmed, update fixed the issue. Thanks for letting me know.
