I've tried running my 5v modem from a 9v battery with a voltage regulator and it didn't work.
I tested the modem directly on the 9v battery, it lit-up, then I think it blew coz there is no more lights at all - oops!
Now, with modem no.2 I've connected it to a 6v latern battery and it works!
QUESTION - Will the 1 extra volt shorten the life of the modem?
If it lasts 1 year instead of 5, thats OK. But if it's gonna last only 2 weeks, that could be a problem.
