Annoying internet performance

[mds96]

Hi everyone

I'm having some really annoying problems with my internet/wireless adapter.

I've tried everything, even to the point of re-installing windows7 (several times), trying old drivers, new drivers, different firewalls, no firewalls, and still no improvement.

My internet performance when I first turn my computer on is fine, but after about 2 minutes of browsing or anything it drops completely, to about 10Kbps.

I know it's just my computer as all other computers in the house don't have this problem.

Diagnosing the wireless connection with Windows Network Diagnostics finds a "Problem with wireless adapter or access point". It says it's fixed (it resets the wireless adapter), and after this everything is fine for about 2-5 minutes, things can download at upto 1Mbps (could be MBps not sure), but then drops back to near nothing.

My wireless adapter is a TP-Link WN851N v2.

Thanks in advance to anyone who can help!

Hi mds96, welcome to the forums

Is your or other computers in the house doing a lot of downloading? For example do you use torrent clients like µtorrent?

These programs will use up all available download speeds unless properly configure to use just a % of it.

A little but our computers are never left on downloading things. This problem happens all the time, even when no other computers are on. If I need something quickly I have to use a flatmates computer because mine will take forever to download or load a page.

What sort of antivirus and firewall do you have running?

I use Comodo Antivirus and Firewall. I've tried at different defense setting levels, I've even tried without using a Firewall at all (well except for the Windows one), still no solution.

When is the last time you ran a scan?

about 1 hr ago. I reinstalled windows earlier today, and only connected to the internet after installing the programs that I use. As soon as my antivirus signature database was updated I ran a scan, and with windows defender also, still nothing.

Do you have a second wireless card that you can try?

 

[mds96]

I think that might be the problem. Does one of your mates have one you can borrow?

Are there other Windows 7 machines connected to your router? What is the make model and version of your router?

Have you tried the lastest beta driver for your tp-link 851N ?
