Flaky Wireless

I’m working here with almost-new stuff. We have a Linksys BEFW11S2 V.2 wireless router about six months old, and an HP-Compaq Presario SR1563CL computer, about the same vintage. The wireless seemed to work all right before the computer, when I and others used it for our laptops. But now, with the computer, the connection occasionally (and by occasionally I mean within an hour of non-use) dies. The wireless software widget on the computer claims to see a strong signal, but it cannot connect using the software. The only way to get it working again is to both reset the router, and to hit a hardware “Connect” button on the computer keyboard, that does I have no idea what, except that when we go through these rituals, the connection comes back up (though the wireless widget may continue to say that it can’t make a connection).

Is anyone familiar with either or both of these de-vices, and able to divine what the heck is going on? It’s obviously majorly irritating.
