Windows 7: Steady degredation of network connection

Steady degredation of network connection

Hello,
I recently upgraded from vista to Windows 7 and I have noticed that whenever I want to visit a website (this one included) i often have to click the link twice for my browser (firefox) to change pages. The first click sends the request and eventually times out. While the progress bar stalls out at about 50% if I hit the link again it goes right to the page. If I go to speakeasy.net and test my connection, 1 attempt will correctly display my 20mb connection, the next attempt shows 2mb, while further attempts either show any speeds inbetween or it will just time-out eventually. My upload speed is always correctly displayed at about 2mb. All other computers on my network have no trouble. I have my network card set for 100mbFD (changed with no effect from autonegotiate. When I try and download files from the internet (drivers, documents from attachments etc...) my transfer speed slowly and steadily degrades from 1mb/sec to idle. If a file does actually come close to fully dowloading, the file ends up corrupted due to data loss, or it cancels completley due to lost connection to server. My motherboard is asus M2N-SLI Deluxe with current nvidia nforce driver 73.1.4.0. Using the device manager, Windows 7 shows my driver to be up-to-date (which is false because it said the driver it found for the card was current, but it isn't) and nvidia's driver manager also shows my driver to be up-to-date.

Even internal network transfers suffer. Files from my fileserver also start out fast and continue to deteriorate to idle.

I'm a pretty novice network person, but i've looked at my router/firewall, device manager, Windows 7 network settings and nothing seems abnormal or unusual.

Like I said, every other computer on my network has 'normal' connectivity and it is just this comp. Any ideas? Thanks in advance

A few common problems that can cause your situation is the Anti Virus (deactivate and see how things work), programs not closing completely (go to task manager (alt, cntrl, delete) and see whats running, when you have the problem) or worst scenario, a virus. Run your Anti Virus to make sure that you are clen. If these things do not help you, right click on network icon and then troubleshoot.

It's not a virus, I tried disabling my anti virus program and it still persists. Also, with just the startup programs running this problem is still plaguing me.

The troubleshooter tells me that everything is fine or it didn't find a problem.

Just type event viewer in search.

go to search type in cmd When you get the cmd prompt type in ipconfig and post here.

I or someone else might be able to give you information from what the ipconfig shows.

- is there a way to output that to a file? i had to hand-type all that in. in linux you can, from a command prompt type something like ipconfig < log.txt and upload the file or at least ctrl-c / ctrl-v

Try this, until others more proficient in network connections come along. Disconnect your modem (some have off switch, mine requires a shut down from power supply ie plug the plug.) Turn off computer, wait few minutes, then boot up and reactivate modem and see what happens.

Why don't you, also, try using IE, see if it gives better results.

i've already tried restarting my modem/router/switch, no change. Also, i don't think it's a firefox issue because network transfers suffer the same fate. i'll give the restart a try though, just to see if i get lucky .

thanks for the suggestions btw.
