Router help..

Hi folks hope all is well.

Renewing mt ISP/Broadband provider shortly.Been with Sky..now thinking of Talk Talk.The only thing putting me off (apart from poor Cust. Service from them-well thats with them all really!) ..is there routers are poor.(again most ISP ROUTERS ARE PRETTY POOR)...anyway...any recommendations welcome . Looking at the web: AVM Fritz!box seem good and more well known names Tplink ; netgear etc...

I use Fibre..but to be honest Iam the only user in the House (Lucky ,me) ..So I could just go for Standard. Snail pace...but want a good signal around my pad esp. upstairs where my SBT SITS via ethernet.

All advice warmly welcome (BTW: Iam U.K. based)
