I don't know if any-one can help me here...

I have a wireless broadband router set up, and my laptop accesses the internet via this wirelessly.

When I'm browsing the net, or doing anything on my computer (Dell Inspiron 5150 Win XP), my wireless network keeps randomly disconnecting, then after a few seconds, reconnects again.

It's really starting to annoy me now, and I was just wondering if any-one could help me out???
