Some providers and SIM cards, especially when using a private APN, will expect PDN 1 to be used or the router will fail to connect.
If your DAL router is not establishing a cellular connection on LTE using a certain SIM card which is known working in another device, the PDN can be change to 1 using the following methods:
WEB GUI (Note: this option is available starting from Firmware 23.9.20.63)
1. Connect to the DAL WEB GUI and browse to System > Device Configuration > Interfaces > Modem (note that the name of the modem interface can be different, like wwan1 for example) > APN List and configure an APN to use Context1:
.png?lang=en-US)
Click Apply.
CLI:
- Connect to the DAL router Admin CLI: by using a serial connection, SSH or telnet, or the Terminal in the WebUI or the Console in the Digi Remote Manager (See DAL User Guide at “Access the command line interface” section for more information).
At the login prompt, enter the username and password of a user with Admin access. Depending on the device configuration, you may be presented with another menu, for example:
IX10 login: admin
Password:
Access selection menu:
a: Admin CLI
1: Serial: port1 (9600,8,1,none,none)
s: Shell
q: Quit
Select access or quit [admin] : a
Connecting now...
Press Tab to autocomplete commands
Press '?' for a list of commands and details
Type 'help' for details on navigating the CLI
Type 'exit' to disconnect from the Admin CLI
>
- Identify the name of the mobile interface: this will be different depending on the model, so, in order to find the correct one, issue the following command:
show network
You will get as result the list of all interfaces, where you can identify the mobile one, two examples below:
IX10> show network
Interface Proto Status IP Address
---------------- ----- ------ ------------------
GRE_INT IPv4 up 192.168.0.1/30
defaultip IPv4 up 192.168.210.1/24
defaultlinklocal IPv4 up 169.254.100.100/16
eth IPv4 up 192.168.2.10/24
eth IPv6 up fd00:2704::1/48
loopback IPv4 up 127.0.0.1/8
modem IPv4 up 37.81.199.214/30
modem IPv6 up
TX64> show network
Interface Proto Status IP Address
---------------- ----- ------ ------------------
defaultlinklocal IPv4 up 169.254.100.100/16
lan1 IPv4 up 192.168.1.64/24
loopback IPv4 up 127.0.0.1/8
wan1 IPv4 up 10.104.1.102/24
wwan1 IPv4 down
- Then, In order to force the modem to connect to Context 1, issue the following command, where <mobile interface name> will be the one identified in the step before:
config network interface <mobile interface name> modem apn 0 cid 1
So, referring to the examples above:
config network interface wwan1 modem apn 0 cid 1
config network interface modem modem apn 0 cid 1
After a reboot, the modem will now try to connect using PDN 1.
