Make and model of computer - Dell Studio XPS 9100
How computer connected - wired
Make and model of router - Linksys AC2600
type of internet connection - DSL
All of my devices had been connected wirelessly - some to the 2.4Ghz network and some to 5Ghz network.
Computer was previously connected wirelessly to 5 Ghz network.
I changed the computer to a wired connection, but now it will only connect to the 2.4Ghz network.
How do I get the wired connection from the computer to connect to the 5Ghz network again?
