Hi,
I was hoping I can get some advice. I have a wireless network setup and recently it's been running very slow. I had the infamous facebook virus a few weeks ago and that's when I noticed the change.

I have a Dell Insprion E1705 running Vista and my wireless router is a Linksys Wireless-G WRT54G. I was eventually able to get my computer back from the virus, but it's been running slow. For example, downloading a 15 minute podcast from itunes takes about 15 minutes where previouslly it took only a couple of minutes.

I keep running all sorts of scans (Spybot, CCleaner, McAfee, Windows Defender) but the problem persists. I even ran Hijack this and analyzed the log but it is still slow.

Any suggestions would be greatly appreciated.

I would download and run WireShark.

It monitors all network traffic from your machine and might give an indication that something is using your bandwidth.

Thanks for the reply. I installed Wireshark, but I'm not sure what I'm looking at. Is there something more straightforward?

Make sure you have the user manual for your Wireless Router. Most of the major vendors offer free 24/7 support for their router products.
Write down their support phone number in case you need it.

I would ensure the system is clean of any Malware or Virus. Then reset the router back to factory defaults (most have a very small hole in the back of the router that when depressed for a few seconds will set it back to the factory defaults). Then go back into the router and setup the SSID wireless settings again and make sure you assign the router a password so that no one can get on it but you for Administrative work.

You can also try resetting your local network card TCP/IP stack back to defaults.

[indent]Microsoft KB article to reset TCP/IP
One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it.
Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh)
