Signals are bad. You could set it to use all bands first so it connects to the best one with better signals.

Code: Select all

AT!ENTERCND="A710"
AT!BAND=00
AT!RESET

As for setting a particular band, it's best you read this tutorial https://wirelessjoint.com/viewtopic.php?f=16&t=364 then post when you are stuck for help so you know more about it.
