Hardware: Linksys EA7500v2
Version: OpenWrt 21.02.1, r16325-88151b8303
My router running OpenWRT works fine until some days ago. Now, when I access LUCI via firefox by http://192.168.0.1
(my configured IP address), it hangs with only the words "LuCI - Lua Configuration Interface" and won't proceed further. I can still SSH into this router. Internet and LAN connections still works perfectly.
I have two other routers of different models configured as dumb AP (192.168.0.2, 192.168.0.3) and LuCI works perfectly on them.
Troubleshooting steps tried:
-
/etc/init.d/uhttpd restart
Does not solve the issue - Rebooting
Does not solve the issue netstat -nlp | grep uhttpd

logread
orlogread -f
It spits out a lot or error messages like the below.

The SQUASHFS seems like the NAND flash is corrupted (and maybe affected LuCI) to me, but I am not sure if this is really the case. Any help in further troubleshooting is appreciated. In particular, I would like to know if it is time to write off the router and purchase new hardware. Thank you.
