Keep your MiFi 3G Router alive when charging with USB

One major gripe I had with the MiFi when I got it was that there was a really silly restriction that does not allow you to use it if it’s being charged over USB. You can use it if it’s being charged via AC Power, but not if you are using USB.

Turns out that all you need is a really simple change to fix this behavior.

• Log into the MiFi
• Go to the Advanced Tab and select Config File
• Open the config.xml.savefile in an editor and look for the node <routeroverusb>
• The default setting is zero, we want to change this to a 1
• Save the file as config.xml and then upload it on the same page you downloaded it from

Once you have done this, you are set. Your MiFi will now work over USB just like it does on AC power. Win!
