Hi,
My RB751G-2HnD & ZTE MF636L together works, but really slow.
I already check everything and figure out nothing.
My RB is configured exactly the same as for my DSL provider, I just change the firewall settings from ETH1 to PPP.
Any idea? I’m shure that it must work faster than 40kbps 
Thanks for help. Regards, Tomaz

Ok, I figure out where could be a problem…
My RB is connected, but don’t want to use 3G but GSM compact.
Where can I set up to use 3G only?
Thanks for help 
Some AT commands may help you
For 3G Only set modem-init:
AT+ZSNT=2,0,0
