Hello,
I’ve got the drivers installed for my wireless card which is a BCM43228 and for some reason I am still unable to see 5GHz networks. I’ve had other operating systems installed on this same machine before and I also ran the iwlist freq command and both of those indicate that I should be seeing the 5GHz networks. Is there something that I need to change with the OS itself or should I try installing a new driver. Also, I am currently using Tumbleweed. Thanks

Hi
Just to confirm, they should be visible via both freq for your adaptor
and scan for the network, eg;
/sbin/lspci -nnk |grep -A3 Network

I checked only with Leap and SLED 12 as don’t have a 5GHz adaptor in my
Tumbleweed test system…
Maybe with your device you may need to try the broadcom-wl package from
the packman repository…

It seems that my card is only scanning on the 2.4 GHz frequencies even though it clearly has a 5GHz frequency:

Hi
So the card/driver is fine from your output. It’s the wifi hotspot your trying to connect to that is ether configured for only 2.4GHz or maybe the wrong country code in the router…?
