Been having some problems with my wireless router lately, but I've found that unplugging it when I'm not using it and then plugging back in seems to help. But I've just got a new odd problem - some sites are opening, some I get a message saying the server's not responding.

I'm in the UK, and I've just noticed that sites that end in ".co.uk" I can get; ones that end ".com" I can't. Mudcat seems to be ok because it's ".org" and I can get those - but not ".net". Weird. Any ideas?
