Frequent loss of internet connection...?

[Squeezemylemon]

I'm using a Philips wireless thingy which is picked up by the built in wireless in my Vaio laptop. I lose internet connection very frequently and the only way I can get it back again is to unplug the Philips and then plug it back in again a few seconds later.

I'm wondering if there is something wrong with the Philips, as the PC that it is connected to doesn't lose internet connection all the time, or if it is just a rubbish broadband provider (it's Virgin by the way).

Thanks for any help.
