Archer c7 v2 100% cpu load

Suddenly getting very high cpu usage, 0% idle to be exact, can anyone explain what is going on here https://i.imgur.com/P2ICKCl.png

I'm not an advanced user and can't decipher what these words mean. Restarting the wireless radio's seems to fix it for a bit, don't know if it's caused by someone using wifi or something else.

Thanks!
