How can I set up a 5GHz band on my EE broadband?

If your router supports 5GHz, the simplest way to do this is by accessing your router settings. From there, you can set up two separate SSIDs: one for the 2.4GHz band and another for the 5GHz band. This way, you can connect your devices to the 5GHz network permanently.

Yeah, I can confirm that splitting the signals into different SSIDs really helps. It's pretty straightforward to get to the router settings—just type your router's IP address into a browser, log in, and go to the wireless settings. You'll see options to differentiate the bands.
