I need to find out which frequency my wifi adapter is using 2.4GHz or 5GHz? How to do that on Fedora Silverblue?

Most routers show the devices and which band they are connected to.
Many routers have the bands named with separate SSIDs to the SSID itself often will tell you which band you are using. One router I have uses separate SSIDs for each band. Another shares both bands on a single SSID.

I don’t know how to tell from the device side except by the SSID and the way the SSID is configured in the router; but from the router side it seems easy with all the different routers I have used. All that would be needed is the MAC address and/or the IP address for the device to verify the connection on the router side.

It is quite simple, but I also had to search for it. The Gnome NetworkManager shows you the speed you are connected with:

Thanks, I use the gnome network manager but had overlooked that info on the screen. Further down it shows the supported bands, but I missed the link speed info.

:+1:

The 2.4 Ghz connection is about 270 Mbps and the 5 Ghz is 540 Mbps and up depending on the actual hardware. My ISP provides a 1 Gbps connection so depending upon time of day I may see upwards of 1000 Mbps.

Check the output:

Both solutions suggested by @ilikelinux and @vgaetera work well. Thank you.
