Internet download freezing and restarting on one system

I have three PC systems in my place. All share the same wireless router, which is a Linksys WRT54GS v.2 with SpeedBooster. Two of the PC systems are working fine with no issues.

Problem Description: Every few seconds, the internet seems to pause and then start again on my desktop computer. Specs included in my profile.

Ways I have tested:

• My girlfriend was playing her online game and it kept freezing and starting up again (this is how I became aware of the problem to begin with).
  
• Downloaded the Windows 7 x64 SP1 integrated ISO and the download also freezes and then starts again. The system itself is not freezing and starting, just to be clear. The amount of data currently downloaded will freeze for a few seconds, and then it will start accumulating again.
  
• Downloaded the Windows 7 x64 SP1 integrated ISO on the other two systems, and it accumulates normally at ~ 1.5 Megabytes per second.

So far what I have done:

• fully uninstalled and re-installed the wireless adapter drivers,
• replaced my antivirus with Microsoft Security Essentials to run with Windows Firewall,
• ran an sfc /scannow that yielded no integrity violations,
• ran system restore to a date prior to when the problem first occurred,
• and restarted the computer between each of these steps.

Any further suggestions would be appreciated.

Hi writhziden,

Have you tested her computer on a wired connection? Please connect it directly to the router? Also, connect it directly to the Modem bypassing the router.

Do issue only persist when she's gaming and downloading? All well when she's only browsing?

Linksys router has the latest firmware?

Can you please post a capture of the Xirrus Wi-Fi Inspector Tool?

An update will be nice.

Glad to hear that restoring a backup image sorted things out for you. :)

As far as router firmware updates are concern, I respect your opinion on taking precautions on firmware updates. Luckily I have not had any bad experience on updating router's firmware which I have done it on different brands of routers and firewall devices (particularly Sonicwalls).

Thanks for the captures, the Xirrus capture looks great and no issue there. Please let us know if the issue comes back.

Thanks for the update. Glad that all is sorted. :)

Does not appear the problem will be returning. I am going to mark the thread solved. Thank you for the helpful tools, though. I will add them to my repertoire. :)
