Literally put my modem out about 6pm last night. It is set to upload 4/day. I believe it has checked in twice so far and uploaded 20 pics. I put brand new lithium batteries in this unit yesterday. It's also new from Bass pro. I live 3 hours away from my camp. My other modems have been working fine sending thousands of pics before they die. Any advice? Send modem in? Try to swap it out at BPS? Batteries didn't even make it 24hrs.
