Inconsistent Wi-Fi
Hi all,
I have a Dell XPS 17 and I am having trouble with the wi-fi. It always connects and works, but is very inconsistent. It will speed up and slow down for no apparent reason. I ran a speed test and it will go from 40mbps to 2mbps. This does not happen on any other device connected to the wireless in the house. It does not happen when the laptop is connected directly. I also purchased a USB wireless adapter and do not have any problems when connecting wirelessly that way. A new modem and router have not changed the problem.
I am 100% sure it is the wireless receiver in the laptop itself. Has anyone had this problem? Any suggestions to fix this very frustrating problem?
Thanks guys,
Chris

Chris,
When you're not using the Medialink MWN-USB150N and you're using the Intel(R) Centrino(R) Wireless-N 1030 adapter, try...
Control Panel\All Control Panel Items\Power Options\Create a Power Plan
Select High performance.
Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
Some members have disabled the Bluetooth for the Intel(R) Centrino(R) Wireless-N 1030 adapter and there speeds have increased.
