Hello !
I updated the packages from SYSTEM-SOFTWARE and after that i get very often the following error when I try to connect to the router's web interface :
"bad gateway
the process did not produce any response"
The wireless adapters are disabled and I can't make WIFI to work.
I still can connect to my router using SSH.
I have a Linksys WRT3200ACM router with OpenWrt 21.02.1.
