5GHz not working

I just got the XF1 setup today and did the setup to have both 2.4GHz and 5GHz. When I connect my PC to the 5GHz my computer slows down tremendously but my other devices seem to be fine. Is this something that is wrong with my PC or router? I have the modem/router xfinity gave me.

Log onto the gateway at http://10.0.0.1 with the default username and password combo of admin/password

If it is your first time logging into it you may be forced to change the password.

Click Connection > Wifi

Two EDIT buttons will show up one for 2.4 and one for 5. Click the edit button for the 5 GHz. Are the channel bandwidth settings at least 20/40/80 selected?

Do you mean that other devices that are on the 5GHz band "are fine", or are these "other devices that are fine" on the 2.4 GHz band ?
