Okay, this is a strange problem...

We have wireless internet access using, I believe, a D-LINK router, my computer is one of several receiving access over the LAN.

It all worked fine until a couple days ago when suddenly I cannot connect to anything. Now, I can browse the internet just fine, which is how I'm posting this, but I can't connect or download files from FTPs, IRC, Bittorrent, or any P2P programs. I thought it was a problem with my computer so I ran spyware removal software and tried restoring my system to an earlier savepoint, all in vain, then I checked and it is a problem affecting all of the computers on our LAN.

Do you have any idea what could be going on? Website viewing works fine but I cannot connect to anything.

Some one got tired of the bandwidth being sucked up by bittorrent & company, and shut all ports down associated with bittorrent, ftp, etc? Check the router and see if there have been any config changes.

Nope, we tried resetting the router settings as well to no avail. Could it be the ISP setting up a firewall perhaps?

Winsock fix?
