| | Re: Tether with DM?
I have the exact same issue. I have updated the ip_modem_configuration in the AT&T section as you suggested. With no luck
The Mobile Internet option now appears in the bottomw left but now it says connection failed when I select it.
When I first selected the button it asked me to confirm which carrier I was using. I selected Telstra as I am on Telstra.
It no longer asks me that question and, as mentioned before, it says Connection Failed. "Railed to start mobile Internet. There was a hardware failure in the modem (or other connecting device).
I have updated the APN on the 9800 to telstra.internet (Options, Device, Advanced System Settings, TCP/IP) which is the same as the xml file.
I also updated the AT&T APN section of the XML file to telstra.internet This is the same as the Testra section of this file.
Your help is very appreciated.
