Better router for WiFi range?

[#1]

Just wondered if anyone has replaced their Technicolour router with something with better WiFi range, and if so, can they recommend anything? Am loving the 80Mb FTTP service but not loving the awful wireless range of the free router supplied - much worse than my previous Draytek. Looking for suggestions for something reliable that can cope with stone walls and some distance outside. Thanks and a happy Christmas to all

What's your budget?
Outside is a bit tricky as the signal can drop off quite noticeably. How far do you want coverage outside?
Where is your router located at the moment?

A combination of homeplugs and an access point might be the best option.

Hi and thanks for your replies. As a temporary measure I have decided to try and use my previous router (Draytek Vigor2820n) as a repeater. I used to have this working well between the Draytek and a Speedtouch 716wl, but I now can't get it and the Technicolor to play nicely. I will post on a more suitable part of the forums to see if anyone can help!
Best wishes
