Internet keeps dropping out

As per the title, my internet is cutting out.

Occurs on both wired and wireless connections. Multiple devices experience the same issue.

Can someone check power levels and arrange for an engineer if required please?

additionally, i noticed my BQM graph is fully red since the 28th at 8pm. prior to this it was relatively normal. i can't find the Allow ICMP setting in my router to see if it works.

additionally, the router interface in general is really slow.
