I've recently signed up to a Usenet package and have been downloading quite heavily over the weekend.

I max out my connection and tend to be downloading at just above 1mb but I've noticed about 3 times over the weekend, that when downloading is finished, and I then to try to use the internet, it simply doesn't work. The broadband (globe) icon on my router is not lit and it requires me to turn it on and off to get it working again.

Problem with the router or the broadband itself?

Any help much appreciated.
