What version of FileMaker GO do you have? Is it the latest version?
I have a reference in the Known Bugs List for FileMaker Go to losing connectivity while on battery, but a bug fix release was supposed to have fixed it.
For More Information see: Network disconnect FM GO while on battery
This is one of many acknowledged bugs that can be found in the Known Buglist for Filemaker GO here in the Report an Issue section of the forum.
It can also be downloaded as a database file from: http://www.4shared.com/file/8orL8apk/FMP_Bugs.html
Thanx, Had seen the update existed - but didn't see that listed specifically as a bug fix... so I was waiting for other users to be the guinea pigs (I'm rude that way).
Guess I'll download it - THANKS
