#### **Known limitations** <a href="#known-limitations" id="known-limitations"></a>

1. The GPS functionality is not supported by OnLogic.
2. SMS (text messaging) is not supported on the VZW firmware image
3. Static IP assignment depends on carrier network and may not be possible or consistent

### SIM Card & Activation <a href="#sim-cards-and-activation" id="sim-cards-and-activation"></a>

* Locate the Extrovert booklet that came with your system.
* If an ICCID number is listed, your system already has a SIM card installed internally and is ready to activate. If not, you will need to provide a SIM card *(Ref: Using External SIM slot below)*.
* Contact your wireless carrier. State that you want to activate a 4G modem and provide the numbers on the front of the booklet.

* Power down and unplug the PC for a moment, then boot it back up.

**Using Modem Manager (Ubuntu Server 24.04)**

For cellular connections, first install the modem-manager snap with:

```
snap install modem-manager
```

Check whether a modem was properly detected via:

```
$ sudo modem-manager.mmcli -L
Found 1 modems:
    /org/freedesktop/ModemManager1/Modem/0 [description]
```

In this case we have just one modem, with index 0 (the number at the end of the D-Bus object path).

Show detailed information about the modem using that index:

```
$ sudo modem-manager.mmcli -m 0
/org/freedesktop/ModemManager1/Modem/0 (device id '871faa978a12ccb25b9fa30d15667571ab38ed88')
```

### OS Configuration <a href="#operating-system-configuration" id="operating-system-configuration"></a>

Now that the modem firmware has been configured, the next step is to configure the operating system. Skip to the section for your OS.

**Ubuntu Desktop 16.04**

1. NWK200 support in Ubuntu 16 Desktop requires:
   * Kernel version greater than 4.7
   * Modem manager from Ubuntu 18.04 or later
2. You will need to make sure you are running a kernel version 4.7 or newer. This can be checked from the Terminal with:
   * `uname -r`
   * If your kernel version is older than 4.7, update to newer version with: `sudo apt-get install linux-image-generic-hwe-16.04`
3. To configure Ubuntu Desktop with the NWK200 model, you will need to use the Terminal to update and install the Modem Manager, along with a few additional pieces of software.
4. From the terminal run the following commands:
   * `sudo add-apt-repository “deb http://us.archive.ubuntu.com/ubuntu bionic main”`
   * `sudo apt-get update`
5. You can now install the new modem manager:
   * `sudo apt-get install modemmanager`
6. Remove the repository:
   * `sudo add-apt-repository -r “deb http://us.archive.ubuntu.com/ubuntu bionic main”`
7. After modem manager has been installed, **reboot** the system and unplug all wired Ethernet connections

**Ubuntu Server 20.04**

1. Install Modem Manager

```
sudo apt-get install modemmanager network-manager
sudo reboot
```

2\. Configure mmcli (modem manager command line interface) so it can interface with the modem

```
sudo mmcli -L
sudo mmcli -m 0 
```

3\. The 0 here is returned by sudo mmcli -L and will vary depending on the configuration. Replace the 0 if the output of the first command differs.

The output of the mmcli -m 0 command will output the modem info. The info we want to grab is “primary port.” This will most likely be ‘cdc-wdm0’ and will be used in the following command in place of \<interface>.

<figure><img src="https://3062424488-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlLHqs7kbNoKOFTwGOfH6%2Fuploads%2Fgit-blob-e374edecc16228706c8e9fba87d878158e014279%2Ff605addbc246335883234a4649e5f293ce15fbc65bf3af207c2217551cab1c56.png?alt=media" alt="" height="831" width="794"><figcaption></figcaption></figure>

\<name> can be set to any value. This will be the name of the connection that shows up in networkmanagers / nmcli. The will be dependent on the SIM in use and it’s respective carrier APN.

```
nmcli c add type gsm ifname <interface> con-name <name> apn <operator_apn>
```

For example, a verizon SIM configuration will use the following commands:

```
nmcli c add type gsm ifname cdc-wdm0 con-name vzw apn vzwinternet

nmcli c modify <name> connection.autoconnect yes

nmcli r wwan on

nmcli c up <name> 
```

### Updating Firmware <a href="#updating-the-firmware" id="updating-the-firmware"></a>

Firmware updates can be downloaded from the Sierra Wireless website linked below.

* Firmware versions are carrier specific. Download the version for your carrier. Use Generic if yours is not listed.
* You will need to register for a free account to download.
* [**Firmware Downloads**](https://source.sierrawireless.com/resources/airprime/minicard/74xx/em_mc74xx-approved-fw-packages/)
* Run the executable and let it complete. Power down and unplug the system from power for 10 seconds. When you power it back up, the new firmware will be active.

### SIM Card Access <a href="#accessing-the-sim-card" id="accessing-the-sim-card"></a>

The modem has its own SIM slot on the bottom side. This is the preferred location to install a SIM card. OnLogic installs all SIM cards here by default.

#### Changing NWK200 SIM Slots <a href="#changing-nwk200-sim-slots" id="changing-nwk200-sim-slots"></a>

The NWK200 comes with two built-in SIM slots. It does not have any provision for automatic SIM switching, so a user must intervene in order to change SIMs.

Follow the instructions to open the AT command terminal *(Ref: Opening the AT Command Terminal).*

**SIM slot 1** on the card connects to **UIM0** on the modem. **SIM slot 2** on the card, or any motherboard slot, connects to **UIM1**.

To select the “operating” SIM slot, run:

* AT!UIMS=n Where n is 0 or 1

A password is not required for this command. If an error is received switching to UIM1 then it is currently disabled (likely by a modem reset).

Use AT!CUSTOM=”UIM2ENABLE”,1 to enable UIM1.

Hot-swapping a SIM card (e.g. via external slot) may reset the selected UIM at which point it will have to be configured correctly again.

### **Troubleshooting** <a href="#troubleshooting" id="troubleshooting"></a>

Before performing any troubleshooting, ensure you have completed all steps in this article and have activated your SIM card.

* If no connection is established after 5 minutes, open Putty and run the following 2 commands. Note that the COM port number may change after switching firmware. You may need to check /dev and adjust Putty accordingly.

<figure><img src="https://3062424488-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlLHqs7kbNoKOFTwGOfH6%2Fuploads%2Fgit-blob-11aaa942f6fb5fe3e478357a92c76b11df7c3e9f%2F7ef78f982aff8553ee5cce8438d6ff177b0cff264cbf5a080e28b1341d70a09c.png?alt=media" alt="" height="184" width="127"><figcaption></figcaption></figure>

```
AT+CFUN=0
AT+CFUN=1
```

This will place the modem into airplane mode and then take it out of airplane mode, effectively forcing it to retry connecting to the cellular network.

#### Diagnostic AT Commands <a href="#diagnostic-at-commands" id="diagnostic-at-commands"></a>
