crazy Internet connectivity

[fait__]

so today i installed windows 10 onto my PC, the wifi was working fine up until i downloaded steam & path of exile, after doing so the wifi is still connected to the router with a strong connection however I cannot use the internet at all.

Is the router still connected to the web? Obvious, but its worth a reset of the router/modem. If you have done that, run a connection diagnosis through windows and see what it comes up with. 9 times out of 10 it will reset the network controller and does usually work.
