Sparky only connects to 5Ghz network
« on: June 11, 2020, 05:18:32 am »
Hello, I am a somewhat newbie Linux user and I am facing the problem in the subject.
I have a dual band wifi, 2.4Ghz channel and a 5Ghz channel, and dual boot in my computer, Linux and Windows.
Every other device in my home can connect to the 2.4Ghz wifi channel but my Sparky Linux, there is no physical problem because I can connect the 2.4Ghz wifi channel with my laptop using Windows.
The 2.4Ghz wifi channel appears in the networks to connect, and when I try to connect it simply does not connect, without any error appearing.
I have an HP laptop 17-bs0xx
I don´t know what to do, thank you in advance.

What might work is to edit the wifi connection - right click network icon>edit connections>wireless

Go to the ipv6 tab and set it to 'Ignore' so it then forces it to use ip4 which is fine for a home network.

Another possibility - depending on hardware - would be to configure your router to deliver 2.4Ghz to the specific MAC address of the wifi card on your laptop.

No guarantees, just thinkin'  :)
