Hrn, here's some guidelines I was looking into in case of issues:-
1. Restart your router!
2. Check if your ISP is throttling your BB
Use measurementlab.net . If throttling then maybe complain to EE's customer service department (who will get complaints daily). Keep records of your communication with your ISP. If you do dump them then look for a new provider who uses Local-Loop Unbundling (LLU).
3. Switch to a faster DNS Server
There's "DNS Benchmark" "DNS Jumper" tools grc.com/dns/benchmark.htm to use for this exercise if desired.
4. Wi-Fi problems would involve further solutions (Channel, new firmware for your router, repeater and positioning of router), but the above are worth looking into if you have a direct connection to your computer. And check none others are using your wifi channel.
After that I guess you're at the mercy of your ISP.
A quick google for general solutions:-
Maybe there is something helpful here. It's just a bit of research I did for my own uses in the event.
