5GHz WiFi To Improve Under Linux With Latest WPA_Supplicant

If you've noticed your 802.11 WiFi adapters on Linux tending to more often connect to 2.4GHz networks than 5GHz, you're not alone, but improvements for 5GHz WiFi on Linux are forthcoming.

Steinar Gunderson has written about improvements in wpa_supplicant Git for bettering the 5GHz support. There are several fixes in Git, default noise values were added for 5GHz by a Google Chrome OS engineer, improvements to the algorithm, and more.

Gunderson concluded in his blog post, "I'm looking forward to these patches hitting mainline distributions (and Android, if Android still uses wpa_supplicant; I honestly don't know); they should hopefully steer AP selection towards 5 GHz much more often. Of course, there's still a lot of work left—802.11 on Linux didn't go from bad to perfect with these two patches, but it's a good start."
