M250 broadband running at 34mbps

so over the last three days or so my pc seems to be running slow, especially when trying to access google related services, I had had same problem with two different browsers, and a laptop was equally slow.

I checked the broadband speed last night and it was recorded at 30mbps, this wasnt quite good enough to watch streaming tv without it buffering every few mins.

this afternoon its up to around 34mbps and this is in the cheshire Sk9 area

I have just done a router reset, and it now seems worse

less than 5mbps at 2.5ghz

15mbps at the 5ghz connection

I am not sure what it normally is, but I would say probably over 100mbps, whats the problem?
