Cant see network.

[mullen]

I was messing around trying to change my modems network channel and accidentally changed my network from 2.4 ghz setting to the 5ghz. And now I cant see my network. I have no connectivity and have no idea how to get it back to 2.4ghz. Any help is greatly appreciated.

There should be a reset switch on the back of the modem. something where you will have to insert a sharp pin or sorts.
Something like this. http://www.online-tech-tips.com/wp-content/uploads/2009/03/wirelessrouterreset.png

Alternatively you can connect a CAT-6/5e Cable (the ethernet wire) and go into configurations page and change the wifi network frequency.
If you can share the model number of the modem, then we may be able to give you a detailed guide.

Hope this helps.
Goodluck
