Appendix 9: AT Commands on the

Router’s Ethernet Interface

eTung’s wireless routers support AT commands directly coming from Ethernet
interface, to query status, modify parameters, send/receive SMS, etc. The AT

commands that a router supports can be different based on different models and

different firmware versions. Below are the AT commands on the Ethernet interface
that MR-900T V1.4.6 or higher versions support.

Attention: the AT commands MUST be in uppercase, and MUST end with CR (0x0d),
as shown in “\r” below.

For the following commands, please refer the descriptions of AT commands via SMS
in “2.5 Remote Configurations”

AT+WN=apn,user,passwd,net_mode\r

AT+DC=addr,port,user,mode\r

AT+PWD=passwd\r

AT+VIRHUB=0/1\r

AT+RESTORE\r

AT+REBOOT\r

AT+STATUS? \r

AT+WN? \r

AT+DC? \r

10.

AT+INFO? \r

11.

AT+VIRHUB? \r

12.
