I dont recall the exact site(s) that i found this on. Someone else asked about this when i found them, but its more like a dish/antenae that strenthens the signal that is hooked up to the wireless gateway/router/ect . The reason why it cuts out is not a batter, lol, but is the cause of not a strong signal, placement of the hardware, walls in the building, other electronic inteferance, faulty nic in the pc. So you would have to troubleshoot these, but after finding out the nic is ok, you may want to try placing the signal in a more open area, away from other electronics, flourescent lights, ect. If thats not the problem, then you will need to buy a stronger wireless antenae
