Fix Dell XPS 13 5GHz wifi speed issues [SOLVED]

When I first connected my Dell XPS 13 to my ASUS router I was quite impressed by the 893Mbps connection speed. However, a few days later and I could not even see the 5GHz wifi network. πŸ™ I was stuck at 144Mbps and not loving it.

After experimenting with the drivers, I determined that an automatic driver update had effectively disabled the 5GHz capability of the internal wifi card and that by reverting to the original (stock) Windows 8.1 driver I could regain those sweet high speed connections πŸ™‚

Basic instructions:
#1 Uninstall the Dell driver
#2 Have Windows search for your hardware and install the default Windows Broadcom driver
#3 Make sure automatic driver updates do not replace your driver again
