My router sucks.
"HEY GUYZ I THINK I'LL RANDOMLY FORGET MY DNS CACHE FOR NOW SO YOU HAVE TO RESTART ME"
or
"HEY GUYZ I JUST LOVE YOU I THINK I'LL RESTART WHEN YOU ARE IN MIDDLE OF IMPORTANT INTRANET GAME"
or
"HEY GUYZ I'M EMO I JUST SEVERED YOUR CONNECTION!"
Oh, you have a Linksys router too?
Amazingly, it fit the 3rd of your list weekly (it wouldn't renew DHCP from my ISP, so I'd have to reset to get new IP), and the 2nd of that list if I ran file sharing apps for more than three or four days)
Though I'm using a Linksys now that I got from Walmart to tie me over, I've ordered an
Asus WL-566GM(If you read its features, yes, ignore the theoretical
208mbps wireless transfer rate. I got it for compatibility with several open source firmware projects)
