I have ZTE MF669 modem and RTL8188eu wifi card.
My wifi address is fixed (192.168.1.14).
Modem gets address from 10.0.0.0/8 subnet.
My wlan connection stops working when I connect to 3G network. I tried with ping 192.168.1.14.
SSH (with putty) disconnects when modem is obtaining network parameters.
Modem connection works normally.
I can't troubleshoot this from console (this is headless system - no monitor, no keyboard).
What is the problem?
