recommend a router?

[#1]

i am planning on buying a replacement router and would appreciate recommendations...
i have an old pc which connects via Ethernet running vista,  but mainly use a recently purchased acer netbook wirelessly running windows 8.1  and a fire tablet. 
i have no tv, games or anything else to connect, and no kids so parental controls are not an issue.
appreciate any suggestions
thanks,  sue

I can recommend the bullion bipac 7800n for long lines , we are a 4.8km from the exchange and since I have installed it my connection has been better and my sycn speed has increased and held, I bought mine second hand for £37

thanks for the suggestion, I don't have a problem with distance from the exchange;  I've always had a perfectly good connection when everything is as it should be.  it appears my problems may be with the router ~ I've been with plusnet over 4 years & have always been very happy but they will not supply a new router (even if it proves to be faulty) unless I take out a new contract...  which i'm not willing to do, so.....

You can get the new plusnet router on eBay for about £15
