Solved Slow WiFi FIXED!


I recently upgraded two Dell laptops, (an XPS M1330 and XPS M1530), from Vista Home Premium to Windows 8 Pro.

Other than a few minor glitches, everything went pretty smooth except for both WLAN cards slowing from a fairly consistent WiFi speed of 270 Mbps down to 54 Mbps.

I have a Netgear WNDR3300 Router and it's working fine. After the installs, I could insert a USB Wireless-N Dual Band adapter in to either computer and get the 270 Mbps speeds back with no problem.

I pretty much gave up on finding a solution thinking that a driver update or something would eventually come along as a fix.

However, after reading that WEP is not the best way to secure a home WiFi network, this evening I decided to change the security setting on my router from WEP to WPA2-PSK [AES]. That change not only made my router and home network more secure, but also returned the faster 270 Mbps WiFi speeds!

I found various possible solutions (and tried a few), when originally researching this problem, but this is the one that worked for me. If you're here looking for a solution like I was a week ago, I highly recommend making this one of the possible fixes to consider.

Good luck!
