XPS 15 Dell Wireless 1830 802.11ac how to prefer 5ghz
Hello,
I would like the Dell Wireless 1830 802.11ac to prefer 5 Ghz wifi over 2.4 Ghz. Its disruptive to go down to the lower right hit disconnect, and then hit connect to get to 5 GHz each time.
Researching this online seems to indicate that this can be done in device manager, but when I go into the properties for Dell Wireless 1830 802.11ac, in advanced there is no prefer 5 GHz drop down to select.
Here is the driver information from this command below
netsh wlan show driver

Like I said I'm tired of discovering I have slow speeds and when I run netsh wlan show interfaces it shows im on channel 6. I have to disconnect and reconnect to the wireless network then run the command again and see I'm on channel 48, then the performance is excellent. However the disconnect, reconnect process is disruptive.
Is there a newer or better driver?

The network choice is selected on your router. Check the directions from the manufacturer of your router.

The 5Ghz band works fine on my Ubiquiti home network.
All of our clients are automatically on it. Prefer 5 GHz is turned on in Ubiquti.
The only time it should go to 2.4 GHz is when the signal is insufficient.
The signal in my office has good 5 Ghz coverage. In fact when the laptop is woken up, all I have to do is disconnect from my wireless ssid, reconnect to it again and then run netsh wlan show interfaces in a cmd window and it shows channel 48 (which is in 5 Ghz) instead of Channel 6 (which is in 2.4 GHz).
The issue is that this Dell 1830 network card does not have this "Preferred Band" option in the driver properties as shown here:

I've seen this on many computers which is why I'm kind of perplexed why it isn't showing on this XPS15.
Again the Unifi AC-Lite access point which is celing mounted provides good 5 GHz coverage to most of the house. I only expect dropping down to 2.4 GHz when in the bedroom.
Speedtest.net shows I can get about 500mbps down when on 5 GHz, but only 80mbps down on 2.4 GHz. That is why I would rather be on the 5 GHz wireless band.

Does anyone know how to modify a driver .inf file to add additional parameters like Prefer 5 GHz ?
