WIFI router frequent disconnects/reconnects

Curious if anyone has activated the AT&T internet service on the Cross and sees this issue. It works for the most part, but any device I use constantly drops and reconnects as if the car's router is resetting itself every 60-120 seconds. This happens even when parked (no tower handoff). Happens on my laptop and tablets. I sometimes have to run a data downloading & processing script for my job from my laptop, and it always fails when using the car's connection because the frequent resets break the data download.
