I'm glad I grabbed the PSP when I left the house today.
It's sporadinc. I can go for weeks with no problem, then when it hits, it's fucking infuriating. I will reset the modem, and it will connect for about 2 seconds, the go off again. It usually lasts for an evening, then possibly the next night.
Lately though, I have been having problems whenever I allow another PC to connect on my network. First it was the laptop, now it's the living room PC. As soon as the 2nd connection goes, it all dies.
