wifi repeater high gain

[jhodgson66]

Hi, basically I travel a lot and often without access to mains electricity. I have a high gain antenna and a usb dongle for a netbook that often works quite well. But now I need to connect multiple devices via wifi often with no mains power. The setup I need is basically a 5v usb powered wifi repeater (5v so it can be powered via power monkey style thing) but not usb only (for use when laptop is turned off) and create a wifi ap that preferably isn't as powerful as the high gain antenna. I hope that makes sense. Feel free to scrutinise what I'm after. any help on this would be great.

I think you should consider changing your power source to a 12VDC source that also has USB. There are going to be more 12VDC compatible devices then there are 5VDC.
