This is a strange problem which has occured about 3 days ago and has persisted for a while now, im not sure if its OS related or if its a problem with my ISP. This thread is really just to see if you guys can help me any further before i go shouting to my ISP that they're being lame 
Ok so connection recently has been poor in several areas, P2P file sharing, bit torrent downloads and internet gaming seem to be all slowing down. I've ran speed tests from websites online and they all report back at roughly the right speed for the connection (512/256) and downloads speeds from single sources http or ftp for instance, are all fine we get pretty much the max speeds for our connection.
However all p2p networks and CS:S (not tested any other games) have problems, before it was fine. I've changed the ports around in case the ISP has capped the speeds for file sharing etc and its not that, i've gone to huge lengths to get bit torrent downloading/uploading at more than about 5k/s to no avail. CS:S we're getting loads of choke and loss, but with pretty good pings, yet when my bro joins on the same connection using ICS and a switch the game gets really bad, massive choke and loss, unplayable, but with reported pings of like 60-80 still, yet the game is pausing for like 10 seconds at a time due to lag.
We have a small LAN here with a switch and we use ICS normally but i've set it up so the modem is in my PC and its still doing it. Things i've recently done which might have caused this problem.
Installed XP SP2
Installed Norton 2005 Anti Virus
I use windows XP firewall and have a reasonaly clean system, no viruses up to date virus scanner, scanned for ad/spy ware with spybot and adware thats all pretty clean. I've heard that SP2 has some problems with virus scanning software.
But i dunno what it is, the best i can describe it is that multiple connections slow down the overall connection to the internet. Its possible its just a large case of packet loss im not sure. Again download speeds and pings seem to be ok, but multiple connections seem to just grind everything to a halt.
Anyways any help or suggestions would be really apreciated, because i want this sorted asap and it feels like a problem at my ISP's end, and as i said, i dont want to phone them up complaining if its something dodgy at my end. Let me know if you need any more info on my system, I arent a n00b, its pretty well setup system and untill about 3-4 days ago was working tip top even with several of us on a network.
