Windows 7: Using 3d apps = internet speed to dropout

18 Feb 2012   #1

Win 7 x64
Using 3d apps = internet speed to dropout

When I open World of Warcraft or Call of Duty modern warfare 2 Single Player my internet download speed drops from 160kbs-220kbs to 0kbs in about 5seconds. Faster on World of Warcraft. Call of duty it takes about 6minutes to drop out completely. When I watch Videos on VLC I think I run about 10kbps slower than normal as well (these are videos on my hdd)

I think it could be Graphic card interference, or a fan interference maybe the processor but not sure. Or else it's its a windows 7 conflict with drivers and such.

I am using my internal wireless card don't currently and probably wont have access to LAN connection anytime soon.

My network adapters
Broadcom 802.11g Network Adapter "BCM43XX64" Using a driver from ASUS laptop site, the driver seems to be better than HP's Old 2009 driver. Cannot find my card on Broadcom's site. How ever the setup I got from ASUS has my card in it so it should be correct. BCM43XX64 Driver Ver. I tested about 5 different drivers from HPs site one of them blue screened me until I safe mode uninstall.

Realtek PCIe FE Family Controller Disabled Driver 7.3.522.2009 from HP site, Win 7 x64

I have a Westell DSL router A90-750022-07 Software VersionVER:
with Century Link internet, fiber optic line, speed test average rural 1mbps internet. Messed with security on router tried resetting it as well nothing helped. I don't think the router is the problem, I could go to Vista and get on online games just fine.

I am the only one the connection at the moment problem still exists

I've Fresh reformatted Windows 7 2x to be sure. This current install isn't fully updated yet but I have all my laptops drivers installed. Earlier I had a fully updated install still had the issue.

Well basically this is huge for me because I haven't been able to play World of Warcraft since I installed win7 and I also I cannot run any 3d application and download / browse at the same time.

Everything worked fine on Vista x64, but I really want to use win7 I get way better benchmarks in almost every aspect compared to vista accept these networking issues.

Things I've messed with, no effect;
Disable / enable Windows firewall and windows defender.
Disable Avast
Install different versions of Broadcom driver.
Run as admin on admin account
WTF fast
leatrix latency fix
Enabling disabling QoS packet scheduler, ipv6, LLTD, LLTD I/O, Sharing, MS cleint. In sequential order.
Tons Different combinations of settings on driver configuration tab.
Changing the channel on router from 8 to 11 to 6 back to 11
updating windows7
updating directx
installing every driver for my laptop
Unplugging mouse / external keyboard and headphones
Turning off sound
Running a bittorrent while playing game or a download. Still cant connect as long as 3d graphics are drawn.

Ahhh wireless, most likely CPU bound thus any heavy CPU usage kills your network connection. That or the drivers are not optimized for Windows 7 thus any hardware support the wireless card supports are not CPU bound...Could also be the security of the wireless, the encryption authentication you use. Using one the wireless card does not support means its done on the CPU.

Win 7 x64

Edit; Nvm converting video now 20kbps slower than idle. confirmed, for some reason windows 7 networking requires more processor? Or maybe it's just a driver flaw for 7.

For some reason by 2009 hp figured laptops like mine had 3months left on warranty so they didn't care about true win7 support.

I wish there was a way well im going to try some more drivers before I go back to Vista x64.
