I'm looking for another portable wireless router .
I used it for youtube show and interviews and timelaps
I need a portable wireless router that the battery can stay for 10 hours minimum. and my video outdoors
Might be worth looking at DD-WRT.
Open source Linux router firmware. There might be support for a portable wireless router. I've had more experience with DD-WRT my router in the garage runs it. Great for an extender.
There are others though.
Otherwise depending on your hardware expertise you could possibly replace or add a larger milliamperes battery or make it switchable with a duplicate battery for longer life depending on how adventurous you are.
@Chainfire - yep I figured as much. The only solution would be to take apart one of the roms from source and manually debug the problem I'm guessing. Since so many roms don't have support for otg on the atrix 2 I'm guessing it's an overall problem. Honestly though the capability is there this should be fixable. I hold hope.

Oh yeah you posted as I was XD or a usb battery would be much easier thanhback and slashing a battery in. Then again I like to play with that stuff.
