Happy Thanksgiving eve! I've got 3 computers running off a wireless LAN. My router is a Netgear router and I have 2 desktops with wireless adaptors and one laptop with a different adaptor. I've been used 802.11b technology. All O/S's on the computers are XP. I've had this setup for 3 yrs with no problems and have been able to connect to the internet with lightening speed.
My computers are running extremely slowly when connecting to the Internet. Just to eliminate the possibilities, I disconnected the router and hardwired one computer to the DSL modem in the hopes that it's something as simple as a bad router. No such luck. The connection speeds are every bit as slow. I contacted my DSL provider and had them run a line check. Everything as normal and is in fact showing as above average speed on their side. I'm thinking the only conclusion left is that I've got a virus on one of the computers, but one of the computers has Norton and shows no viruses, the other desktop uses a free antivirus software out of Germany, and the laptop (which I rarely use) I just go to a website like trendmicro for a free virus scan. Everything comes back clean.
My question: how next should I proceed to diagnose the problem? Should I run hijackthis on all 3 computers and submit separate logs? This whole thing is really giving me a headache and I'm getting too old to spending time until 3:00 a.m. trying to dianose the problem!!
I'd be grateful for some advice. Thank you.
