I've been using my glinet with openwrt (not stock) for months. In this new house it seems it can't keep the connection stable to the main router provided by the landlord.
I have the latest from https://downloads.openwrt.org/releases/21.02.1/targets/ath79/generic/openwrt-21.02.1-ath79-generic-glinet_gl-ar750-initramfs-kernel.bin
With openwrt non-stock in logread I see:
Sun Oct 24 10:13:18 2021 daemon.notice wpa_supplicant[1505]: wlan0: SME: Trying to authenticate with <x> (SSID='common' freq=2462 MHz)

it can't connect.
My computer can directly connect to that common wifi.
There are 4 access points with the same name and password on different channels, could this be an issue? I lock by BSSID too but it does not fix the issue.
The date-time is off and I set it correctly by date -s ... (because the router can't reach any ntp server of course).
If I use glinet stock, it disconnects and reconnects every 5 minutes.
I have 3 glinet and all of them have this same issue here
