HIgh CPU 99% and a CSRF Message

[oznet]

This past evening my router for some reason stopped working as netflix was playing checked the cpu usage and was up to 99% at times so I rebooted to restore internet and finished netflix but cpu was bouncing all over the place.

This morning I was prompted with a red screen something about a CSRF token?? not knowing what to do next I resubmitted the form data for a new token. I probably made a bad choice but I removed the 2100 running the latest firmware and using Firefox to admin the box and Win 11.

I installed my old router until I find out what to do with the 2100. I am not running any plugins. Just a bare 2100

@oznet I think I answered you on Reddit but CSRF is most likely you left your login page open too long and the token expired. Just refresh before logging in.

As far as CPU, Diagnostics/Activity or run top at console and see what is using CPU.

Check Diag > System Activity or top -HaSP at the command line. What is using the CPU cycles when this happens?
