So I have this 4G Router and in the settings there is a wifi band option and I can choose between 2.4Ghz and 5Ghz. Can someone tell me what the difference is? BTW it's set to 2.4 by default.
 
2.4 GHz is an older standard and shared with cordless phones and other devices. There tends to be more congestion on 2.4 GHz, but it also better going through walls.

5 GHz is a newer standard and can carry has higher bandwidth (faster). There is less congestion and more channels at the 5 GHz setting, but it is less effective at going through walls.

Which should you use. If you can get a good connection at 5 Ghz, I would use that. It has the potential to be faster. If your connection is dropping out or lagging, try 2.4 GHz. It's slower, but more reliable.

**edit** Some devices (phone, printer, wifi adapter, etc) don't support 5 GHz. If that is the case with your devices it could limit you to 2.4 GHz (or looking for an upgrade!).
 


Sounds good! Thanks for the help!
