Download Speed really slow

[TableTiger1]

Okay I am having a problem with my wireless download speed. I have a desktop pc that has windows 7 pro installed. I purchased two different wireless pci n cards and both have the same problem. My download speed is terrible. On speedtest.net I get maybe 2 mb/s. My upload speed is normal, hovering around 5 mb/s. I can't seem to figure out what the problem is.

I have 4 or 5 bars on signal strength and my signal speed varies between 160-270 mb/s. I currently have the Netgear WIRELESS-N 300 PCI ADAPTER WN311B installed. My router is also a Netgear N and the settings are set to 270 mb/s for speed.

My laptop also has windows 7 pro installed but has only a b/g card that runs at 54 mb/s. On speedtest.net I get 20 mb/s down and 5 mb/s.

What gives? The upload speeds are the same but something is throttling the download speed on the desktop. Is there a setting in windows or the mobo that will change the problem. I am using the driver that windows installed for the device. It is a broadcom 802.11n driver. If I connect the desktop with a ethernet cable I get the same speeds as the laptop.

Thanks for the help.

open a command prompt and run:

netsh int tcp set global autotuninglevel=disabled

re run your speed tests and let me know.

I tried that and got the reply Set global command failed on IPv4 The requested operation requires elevation (Run as administrator)

Also my network is secured with WPA2-Personal AES, not sure if that matters.

Problem solved. I changed the speed setting to 130 instead of 270 and it works fine now

Elevated mode = run as admin. You can set this for cmd when you go to All programs > Accessories > right click on Command Prompt > Properties > Advanced > check the box "always run as admin". Then it will always run in elevated mode. Else you will have to right click on cmd and "Run as admin" each time.
