Is there a way to prefer 5GHz band to 2.4GHz band (without disabling 2.4GHz altogether) for a specific wifi network (SSID) without setting BSSID or failing that for all networks?
I am using Mint 18.3 with Cinnamon 3.6.7's network manager.
I have a new Dell XPS 13. Kernel is 4.13.0-26-generic.

Background: The routers are in an office so I cannot alter their setup. I can only do things on my laptop. Also it is the initial connection more than roaming that I am thinking of. When I connect to an SSID in the office at my desk, I would like it to prefer 5GHz to 2.4GHz (because the 5GHz signal is stronger), but right now it connects to 2.4GHz by default. Although I can set the BSSID to a specific 5GHz one which works well at my desk, this is not a good solution because if I do move around the building, I have to unset it again to allow roaming to work. I was advised by IT support to choose the prefer 5GHz option in Windows, but I am running Linux.
For Windows: On right side of taskbar > Right-click on network icon Choose Open Network and Sharing Center Select Change adapter settings Find your Wi-Fi connection (your connections will differ) Right-click, Properties > Configure > Preferred Band to 5.2GHz Click OK
