Nighthawk M2 MR2100 Telnet command: Disable CSD mode (circuit switched data)

[Alexsey1]

Dear all,

I am looking for the correct telnet AT command and syntax to DISABLE CSD mode (PSD mode / packet switched data only).

Background: When connected via CSD, a cellphone using a so-called "Multi-Card" (additional SIM-card with the same number) does not ring any more.

With the Nighthawk M1 (MR1100), the following AT-command did the trick (permanently):

AT!SELMODE

I expect something like

AT !COMMAND

with a space in the syntax, however nothing I tried (including setting passwords separately) worked.

Thanks & Best regards

Alex

I will send the MR2100 back.

Netgear did not reply on my pro support case either, and we did not manage to find any working AT command for that matter.

Will stick with the MR1100 instead.
