When I went into the network properties when i was connected to a specific home wifi, I went to the configure intel settings and changed the band width to 5.2 ghz and now I am completely unable to connect to that wifi and cannot change the band width back to how it was before. is there any way to change it back?
You really should be able to change it back. you can try going in via device manager and the properties of the wifi card, see if there are any options in there. Otherwise you may need to consult the intel help documentation/call them
