Internet Connection slow to a crawl playing flash vidoes

[V00DOO]

Computer setup Window 7 Pro, AMD Phenom II quad cores, 8gb rams, 10/100/1000 lan. AT&T 12MB DSL. All updates have be performed. Everytime I play a flash video either from Youtube or any other places, the video would stop downloading shortly then my internet connection on my PC would slow to a crawl. For example, right before playing a flash video I would perform a speedtest.net test and gets around 1.1mb download. After playing a flash video the same test resulted in .1mb download or wouldn't even run. I have tried uninstalling adobe flash then reinstall. Uninstalled Firefox and deleted all contents pertains to Firefox then reinstall to no avail. It happens on IE too. The only way to fix this problem is by rebooting. I have 5 other computers running on the same networking without having this issue. Beside reinstalled Win7 any suggestions. Thx.

Did you try installing the latest JavaRE, Version 6 Update 30 ,and then installing the latest (v11.1.102.55) Adobe Flash Player ?

I don't know the version JavaRE. I'll update it as soon as I get home from work. Yes Flash Player is the latest.

I updated to the latest Java and it appears I could be a few videos before the slow down. It's not only the internet that slows, my connection to other computer are also very slow. Perhaps I should post in the Networking forum.

Open Task Manager and see what CPU and memory usage looks like when your connection slows down. Also check processes to see if there are any you don't recognize and/or are using a lot of CPU. If this just came out of nowhere you may have picked up malware that starts running in the background as soon as you open your browser.

Even if you've got AV you should try running a scan with Malwarebytes Anti-Malware Free. It'll detect malware that a lot of AV's don't.

I have Malwarebytes Pro on my system and scans on a weekly basis. I scanned with Hitman Pro, Hijack this, etc. My CPU/Memory usage are minimum. I have looked at the Processes under taskmanager and nothing unusual is running. I can surf the net all day and it'll be fine without playing flash videos.

You might see what happens with Chrome. It has its own flash player.

I think I finally solved the problem by updating to the latest Realtek NIC driver. Apparently the built in Windows driver had an issue with 1Gb lan.

I hate so much flash content...why people who are making sites just don't go with HTML 5. Much better and at the same time less requirements on the computer.

I have this very same issue, my internet connection works JUST fine, everything as it should be, the second I open any kind of stream in Firefox (haven't tested other browsers..), my connection slows to a crawl, or just simply stops working - for BROWSING. I can ping google.com just fine with 20ms (from Denmark) - But I can't browse whatsoever, and half the time the video doesn't even start. Then when it's done loading, and the stream begins my browsing is sort of fine again, though feels slow.

Any help would be appreciated.
