Windows 7: Internet Connection not recognized

vileguy, I've had such problem once with my setup too... The culprit was my WRT54G, it's memory is all clogged up by the DNS records from my bittorrent client's connections, memory full, it can't add a new address to it's memory, results a 404 not found... After I update the firmware, that issue went away (the update does state about memory management). While you're at it, try this... when your connection seem to be unavailable, stop everything, ping to 208.77.188.193 (it's IANA — Internet Assigned Numbers Authority), if it does reply then your router is indeed still connected... next you test by typing this command in command prompt "nslookup www.iana.org", see if it resolve the hostname to IP, if it fails then maybe your router's memory is all clogged up, it needs sometime to clear it's memory of unused connections. zzz2496

Well it had been a while since it happened but it did. I have new internet service (comcast, formerly had earthlink). Now I have a really hard time capping my download/upload unless I try. Well my issue occured, I was talking on vent while I did this ping and my friend next to me was playing a game over the internet without any problem. I'm on wireless and he wired but I've had the problem with both, it's windows or my lan drivers not the router. Here's what the ping showed:
