Dell XPS 15 (L502X) Wireless Issues – Fixed

I recently bought a new Dell XPS 15 laptop. Dell was having an Easter special (30% discount) so I maxed it out with features (quad-core i7, 8GB RAM, 256GB SSD and full HD screen). Its a nice laptop and I was hoping that the numerous reviews I’d read regarding issues with its Intel ® Centrino ® Advanced-N 6230 wireless adapter would have been solved. I was wrong.

Slow as Molasses

My Macbook was achieving 30Mb/s downloads via my cable modem but the new Dell was only managing between 1 and 4Mb/s and even then it was patchy. I tried out the main suggested solution which was to configure the wireless adapter settings in the power options in Windows 7. This did not help.

Intel Drivers

I came across a forum suggesting that the Intel drivers rather than those from Dell would solve the problem. I downloaded and installed the Wireless_15.1.1_Ds64.exe file from the Intel Download Centre. It solved the issue and now I am getting 30Mb/s downloads via my Dell.

Update – 8th Oct 2012

You could also re-install your machine with Windows 8! I upgraded to Windows 8 this weekend and have not had to install drivers from either Dell or Intel. My wireless is working perfectly and even some of the minor annoyances I’ve still had to put up with have disappeared.
