I just installed a new openwrt firmware on my linksys wrt1900ac router. Tried to connect dorbell and camera but both failed connection. When I tried to add a new device c210 on tapo camera app. my wifi wrt1900ac is not able to choose and instead of wifi signal bar there is a WEP in a circle. Please see attachment. What should I change in a settings to fix this issue?
Post your current settings to start with?
If you're using WPA mixed mode, disable it.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

why is your app in PL, but radio settings FR and GB ?
I am Polish that's tapo camera app. is in Polish language. GB because I lived in UK. FR was setup after firmware instalation. I will change it to GB.
I'm assuming that the device thinks your AP is using WEP security and refuses to connect because WEP isn't supported. But your AP is not using WEP -- it's clearly configured for WPA2 encryption.
I'd start by changing this to channel 1, 6, or 11 (the three non-overlapping channels available on the 2.4G band). If that doesn't fix the problem, try setting no encryption (just as a test) and see what happens -- will it connect?
What is the camera you are trying to connect?
Camera tp link tapo c210 tested on chanel 11 works fine without encryptions
Update:
Chanel 1
No encryptions - no issue, camera connect with router
WPA, WPA2 or mixed - unable to connnect camera, WEP in a circle
Problem solved, just allowed legacy 802.11b rates on wireless settings

Wow, that thing must be really old, or buggy.
