Issue connecting to some devices

Hi, I have installed OpenWRT on my TP-Link Archer C7 v2 and had been using it from last 2-3 years. I noticed recently there are a few devices which do not connect to my internet but do connect to other connections - 1 fire tablet and 1 google chromecast TV. They were able to connect earlier for sure - but I did update to latest openwrt 6 or so months back and these devices were not used since.

I updated to latest openwrt now (OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a) but still these 2 devices are not able to connect. I tried to see if I can see the mac address of these using logread - but I dont see any logs for these 2 macs. Any tips on how to troubleshoot?

Thanks!!

SSH in to the router and run cat /etc/config/wireless.

Redact the passwords in the "option key" sections.

Several devices don't support mixed.

Try WPA2-PSK with AES.

If you have devices that do, you might consider setting up a guest/IoT network specifically for them.

Try using wpa2 personal. Older devices may not work well with mixed mode wpa2/3 encryption

Setting to this solved the issue. Thanks for such a quick response!

WPA2 PSK (CCMP)

option encryption 'psk2'
