How to manually switch Wifi bands on the Surface Pro 3

With Microsoft's recent firmware update for the Surface Pro 3, among the new bits and pieces was a new Marvell Wifi driver that lets you switch between 2.4GHz and 5GHz bands on the fly. For those of us using a dual-band router, the updated driver should help resolve any related issues.

Switching bands is easy, so long as you know where to look. Here's how to do it.

  • Using the universal search on the Start Screen, search for "Device Manager."
  • Open Device Manager
  • Find "Network Adapters" in the list and expand it
  • Tap and hold or right click on "Marvell AVASTAR Wireless-AC Network Controller" and open its properties
  • Along the top of the dialog box, open the Driver tab
  • Verify the version number is 15.68.3073.151 before continuing
  • Assuming all is correct thus far, hit the Advanced tab. This is where you'll change bands.
  • The dropdown "Value" box on the right will have options for 2.4GHz, 5GHz and Auto when the Property box on the left has "Band" highlighted.
  • Select your desired band, hit OK, and you're good to go!

One thing worth noting is that should you specify only 2.4GHz or 5GHz, your Surface will only connect on those bands. If you then leave the house and try to connect to Wifi elsewhere, it's worth making sure you've set it back to Auto to keep things running nice and smoothly.
