I bought a new laptop last month and still found the internet slow on some sites, this one being one of the worst. I spoke to Sky (broadband supplier) about it and the result was a new router would be the answer. Well I wasn't born yesterday so said "Yeh yeh more money to spend but no guarantee it would solve the problem. Anyway router arrived today, instalation took only minutes for 1 PC and 2 laptops and guess what, no more chuggy chug chug. My lovely new super fast laptop is now so fast I can't type quick enough to keep up with it
The Sky Tech guy was very informative, the problem most people have is they buy new computers/laptops and forget to upgrade the router (his words not mine). So have you bought recently and are disappointed with speed performance? (not talking running now guys and girls ) then try a new router, it may just be the solution.
