# Mobile Protocols

There are two different mobile protocols built-in the EZR24 router. The default mobile protocol is **Mobile Data**. Suggest using the default protocol unless your mobile provider does not support it.&#x20;

### **Mobile Data Protocol**

The **Mobile Data** protocol is based on **QMI**, *Qualcomm MSM Interface*, which is a proprietary protocol that offers more accessible and faster connections to mobile networks.

Due to the difference in the modem chipsets, the different mobile modems might use different QMI proxies. For example, Sierra modems use the *QMI\_WWAN proxy,* and Quectel modems use the *GobiNet proxy*. These proxies use the same QMI protocol and provide similar working performance.

The primary difference is that *GobiNet* uses kernel space, while *qmi\_wwan* uses user space. And in *qmi\_wwan*, only one process can handle the control port at a given time, while the *GobiNet proxy* allows multiple processes to access the device concurrently.

### **4G-PPP Protocol**

**PPP**, *Point-to-Point Protocol*, is a traditional data link layer communications protocol. PPP protocol has been very widely used and is most flexible for interoperability with devices.

Some mobile carriers might not support QMI protocol to connect to their mobile networks. So we must change the mobile protocol from the default *Mobile Data* protocol to the *4G-PPP* protocol.

### Switch to PPP Protocol

Under `Common Configuration` > `General Setup` of the Mobile interface, choose `4G-PPP` on the dropdown menu of `Protocol`. Then click the confirm button `Switch protocol`. It will jump to the 4G-PPP protocol setup page.

Comparing with the `Mobile Data` protocol, the `4G-PPP` protocol has two extra configuration fields, `Service type` and `Dial number`. The other parameters, including APN / PIN / Username / Password, are the same configuration operations as the QMI cellular protocol.

* `Mobile device`: Choose `/dev/ttyUSB2`
* `Service type`: Due to differences in mobile network standards, choose the services as below:
  * `UMTS/GRPS` for the UK / European / Australian versions
  * `CDMA/EV-DO` for the American versions
* `Dial number`: Use `*99#` for European standard network, and use `*99***1#` for American standard networks.

Click `Save & Apply` button on the bottom right corner to apply the new APN parameters. Then back to `Network` > `Interfaces`, and wait 1-2 minutes until the mobile modem reconnects to the mobile network.&#x20;

![Switching EZR24 Router to Use PPP Protocol](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXrJBTozkgaqqeDtauCDH%2Fuploads%2FgcLVCzJ1iGVVx0R5kGrL%2F4G-Router-Firmware-Switch-to-PPP-Protocol.jpg?alt=media\&token=1c5a83d4-2911-4770-8661-65dbcd94f1dc)

{% hint style="info" %}
To switch the protocol back to Mobile Data, select "Mobile Data" from the protocol field and click the "Switch Protocol" button. Then configure the parameters as shown on the default [mobile modem settings](/manual/3-firmware/3.4-mobile-modem).

# Mobile Band Lock

In some rare conditions, such as between two cell towers, we need to lock the 4G router to work on a specific band to get a stable connection or faster speed.

### Supported Mobile Bands

The CAT12 mobile modem on the EZR24-012 router supports the below bands.&#x20;

Before locking the band, please ensure the bands you want to use have at least a "Fair" signal reception in your area. Please refer to the [signal test tutorial](https://www.outdoorrouter.com/field-test-4g-mobile-signal-strength/) to check the signal strength.

### Lock Modes & Bands

The EZR24 firmware has integrated a web interface to lock network modes and mobile bands easily.

After accessing the router's admin page, go to "Network > Interfaces > Mobile: Edit." Click the tab  "Advanced Settings."

**Supported Modes** are 3G and 4G. Suggest enabling both of them.\
**Preferred Mode**: Select 3G or 4G on this field.\
**Support Bands:** Pick up the 3G and 4G bands by enabling the checkbox.\
**Signal Refresh Rate:** Suggest inputting "10\~30" seconds.

**UTRAN** is the Radio Access Network Architecture of 3G UMTS, while **EUTRAN** is that of the LTE.

Click the "**Save & Apply**" button on the bottom right corner to take effect of the above settings.

Wait 2\~4 minutes until the mobile interface connects to the cellular network. If it has failed to connect to the mobile network, suggest reviewing the signal reception of the selected bands in your area.

# 3.7 Recovery

Fix the issues on the Internet and wireless networks and rescue the router from misconfigurations.

## Reboot Router

Like a regular computer, the EZR24 router has a Linux-based operating system. Rebooting the router can solve mysterious problems, fix Internet connectivity issues, and improve security.

The Internet provider assigns a temporary IP address which can be changed when timeout. If the router misses the change, the Internet connection might become slow. The same can happen if too many devices are connected to the router. For example, the routers found channels with less traffic and increased performance speeds while rebooting.&#x20;

#### i. Soft Reboot

After accessing the router, go to `System` / `Reboot`, you can perform a **soft reboot**.

#### ii. Hard Reboot

To do a **hard reboot**, please unplug the PoE adapter wait a couple of seconds, and connect again.

{% hint style="danger" %}
Do not disconnect from the PoE adapter while flashing firmware and resetting the router.
{% endhint %}

## Factory Reset

After running a factory reset, the router will erase configurations and return to the factory default settings.

### i. Soft Factory Reset&#x20;

1. After accessing the router, go to `System` > `Backup / Flash Firmware` > `Actions`: `Restore`.&#x20;
2. Click the red **`Perform reset`** button and click the *Confirm* button on the *pop-up* window.&#x20;
3. The router will go to the System - Erasing page. The system indicator flashes while resetting.
4. Wait 3-5 minutes until the router completes the resetting progress and reboot.

### ii. Hard Reset

On the EZR24 router, there is a *Reset* button between the DC socket and LAN#4 port.&#x20;

1. Power on the device and wait until the router successfully boots up. The System indicator stops flashing.
2. Press and keep pushing the Reset button for 5 seconds.
3. Release the *Reset* button.
4. The router starts to reset the firmware, and the system indicator flashes while resetting.
5. Wait 3-5 minutes until the router completes the resetting progress and reboot.

{% hint style="danger" %}

* Before disconnecting from the power source, ensure the router completes the resetting progress and can access the router's admin page.
  {% endhint %}


# 4 Advanced


# 4.1 Internet & IP

Run a first quick Internet access test to check Internet connectivity.

## Internet Connection

You can quickly check the mobile connection on the `Device information` section on the front page or go to `Status` > `Overview`.&#x20;

* After successfully setting up an Internet connection on the mobile modem:

  * The `Mobile Connection` field on the column of `Device` information will shows `Connected`.
  * The `Network` section will show the current mobile network gateway in the table of`IPv4 Upstream`.

  \
  *or*<br>
* Go to `Network` > `Interfaces`, the `Mobile` interface will show `Rx/Tx` rates.&#x20;

  * The `Mobile_4`interface shows the `IPv4` IP address. *\*For `QMI protocol` only.*

  \
  *or*<br>
* Go to `Network` > `Diagnostics`
  * Click on the `Ping` button or use the command `ping outdoorrouter.com` on the `Command-line` .
  * it should return `0% packet loss` if everything is alright with the Internet connection.

## IP Address

Go to `Network` > `Interfaces`. On the rows of `Mobile` or `Mobile_4`, you can find the IPv4 IP address obtained by the mobile modem.

### Public IP Address

The mobile carrier usually provides a LAN IP address for the mobile connection.&#x20;

To verify the public IP address, you can first check the above IPv4 IP address obtained by the mobile modem. Then search *My IP* on *Google* and compare the returned public IP address with the IPv4 mobile IP address.&#x20;

If they are different, it means your router uses a LAN IP address from the carrier.

{% hint style="info" %}
If you have the public IP address and require to access the router remotely at the public IP address, please refer to [Changing Web Port](/manual/4-advanced/internet-ip/changing-web-port).
{% endhint %}


# Changing Web Port

Guidance of how to change the Web GUI interface port on the EZR23 router.

The internet operators usually block 80 ports, which are used by the web interface of the EZR24 router. To access the EZR24 router remotely on the public IP address, we need to change the port for the web interface.

When the router is turned on, access the command-line interface. Input the below command `vi /etc/lighttpd/lighttpd.conf`. Now we are in the *command mode* of the VI editor.

* Press "i" on the keyboard to enter the *insert mode*.
* Scroll down to line No.89. The original code is `#server.port = 81`.
* Delete `#` and change the server port to `880`, for example.
* Press *ESC* on the keyboard. Exit from the *insert mode* to the *command mode*.
* Press `: wq` on the keyboard to save the file and exit the SSH terminal.

Input the below command to restart Lighttpd `server /etc/init.d/lighttpd restart`.

```
######### Options that are good to be but not necessary to be changed #######

## bind to port (default: 80)
server.port = 880
```

Now we should re-login the router admin at `http://192.168.20.1:`**`880`**. If your router has a public IP address, you can access the router at `public-ip-address:880`.

*\*Except uses the VI editor, you can also use an **SFTP** client software, like **WinSCP**, to edit the `lighttpd.conf` file.*


# 4.2 Firewall Settings

The router firewall controls the forward packet streams from incoming network interfaces to outgoing network interfaces.

Firewall rules add another layer of granularity to what is allowed to be forwarded across interfaces and additionally which packets are allowed to be inputted and outputted.

## Firewall Zones

The firewall can collect interfaces into zones to filter traffic logically. A zone can be configured to any set of interfaces. This simplifies the firewall rule logic somewhat by conceptually grouping the interfaces:

* A rule for a packet originating in a zone must be entering the router on one of the zone's interfaces,
* A rule for a packet being forwarded to a zone must be exiting the router on one of the zone's interfaces.

After accessing the router, go to `Network` > `Firewall` to enter the `Firewall - Zone Settings`.The `SYN-flood protection` is enabled by default. You can use the below default firewall zone settings in most of the conditions.

![Default firewall zone settings](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-LxZyv7tzLU4F4jop0jB%2F-LxZz9MrAVtqrSRJv0k4%2Fimage.png?alt=media\&token=9673f210-91f5-4f3b-a4cb-55f2bd4a7c49)

## Port Forwards <a href="#port-forwards" id="port-forwards"></a>

Port forwarding is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another. Port Forwarding allows remote computers to connect the outdoor router within a private local-area network (LAN).

### i. General Settings <a href="#i-general-settings" id="i-general-settings"></a>

Log in to the router, go to `Network` > `Firewall`. \
➀ Under the tab of `General Settings`, change forward to `accept`. \
➁ In the **Zones** section, change the **Forward** on the row of **WAN** from `reject` to `accept`. \
Click the **Save & Apply** button on the bottom right corner.

![](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVQO0M7JyKjsTjBm_%2Fimage.png?alt=media\&token=c44784c9-41e8-4ede-9e25-f13a669aff4b)

### ii. Port Forwards (WAN) <a href="#ii-port-forwards-wan" id="ii-port-forwards-wan"></a>

Click the tab `Port Forwards` to enter the configure section on the **New port forward** section:

1. `Name` : Enter the reference name. e.g., *`Test`*
2. `Protocol`: Select from `TCP`, `UDP`, and `TCP+UDP`

   📌 *If you don't know the protocol, please choose TCP+UDP. Please select TCP or UDP if you are aware of whether it is TCP or UDP. It can effectively reduce resource consumption.*
3. `External zone` : Select `WAN`
4. `External port` : Set the port number want to access from the external network \
   📌 *Suggest selecting the WAN port between 1025\~25534. Do not use the standard ports occupied by the other services such as 23, 80, 433, 3389, 7700, 10080, etc.*
5. `Internal zone` : Select `LAN`
6. `Internal IP Address` : Select from the list of connected intranet hosts \
   📌 *If you can not find the host on the list, please recheck the IP settings on the host.*
7. `Internal port` : Choose the port number which needs to forward from the intranet host
8. Click the button `Save & Apply`

The below example was forwarded to localhost *192.168.30.113:80* to WAN port *1180*. You can access the *80* port on the host of *192.168.30.113* from the public IP address plus port *1180*. It's NOT accessible from the router's local IP, e.g., *192.168.30.1:1180*.

![](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVbryHoe0XevYYz94%2Fimage.png?alt=media\&token=88198e7a-c091-4e2d-b929-e1cc22c9403b)

**NAT Loopback** is turned on after saving a new port forward rule. It allows the intranet terminal to access the local hosts using the public IP address of the routed external network interface. To reduce the consumption of router resources, you can click the **Edit** button on the saved port forward rule list to disable it.

​

### iii. Intranet Forwards <a href="#iii-intranet-forwards" id="iii-intranet-forwards"></a>

To access another host from the router IP address, we can set up intranet forwarding based on `iptables`. Go to the tab `Custom Rules`, add the new iptable rules. Below are the example codes to forward 192.168.30.113:80 to router IP 192.168.30.1:1180.

`iptables -t nat -A PREROUTING -d 192.168.30.1 -p tcp --dport 1180 -j DNAT --to-destination 192.168.30.113:80 iptables -t nat -A POSTROUTING -d 192.168.30.113 -p tcp --dport 80 -j SNAT --to 192.168.30.1`

# 4.3 Dynamic DNS

Dynamic DNS allows that your router can be reached with a fixed hostname while having a dynamically changing IP address.

**Dynamic DNS** service binds a domain name to public IP on the router. Then you can access the router remotely from the DDNS domain name without discovering the IP address.

After accessing the router, go to `Services` > `Dynamic DNS`. Modify the fields you need to change. Don't forget to check the `Enabled` option! Click `Save & Apply` button to save changes.

![Overview Dynamic DNS](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-LxZyv7tzLU4F4jop0jB%2F-LxZzMVy2CcFWI-y2nWn%2Fimage.png?alt=media\&token=f97f5ddb-1a7e-451c-96f1-111791710ec7)


# 4.4 Traversal Cloud

Traversal Cloud is a secure NAT tunnel tool to provide remote control function on the 4G outdoor routers and connected hosts.

After enabling the **Traversal Cloud**, you can access and control the 4G routers anytime, anywhere, on a web browser. It offers the easiest way to look over your networks. No public IP address and DDNS configuration are required. **It’s completely free!**

![Working principle of Traversal Cloud](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-LxZzYuGbAiN0fLsLmCp%2F-LxZzfF5v0Y8MgiDucms%2Fimage.png?alt=media\&token=e42b2709-07d0-4a37-a14d-2ca98b1f5cde)

# 4.6 Bootloader

Rescue the EZR24 router from the "brick" mode.

The router will be stuck in the reboot cycle when the firmware is incomplete or broken. The router keeps rebooting, and WiFi & LAN cannot hold for more than 3 minutes.

It usually happens because of deleting critical files or disconnecting from the power supply while resetting or flashing firmware. The EZEN4X series, including the EZR24 router, has a built-in uBoot bootloader to re-build the firmware system.

### 4.6.1 - Static LAN Connection

Connect a computer to the LAN port on the router. Then, configure the below static IP address on the computer.&#x20;

Computer IP: 192.168.1.150 \
Router IP: 192.168.1.1 \
Subnet mask: 255.255.255.0 (also called 24 on Windows OS)

![Example of Static IP Address Setting on Mac computer](https://2031239798-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXrJBTozkgaqqeDtauCDH%2Fuploads%2FHyjD1l8wegaqaP2Os6zG%2F4X_uBoot-Steps_Static-IP-Address-LAN.jpg?alt=media\&token=0583e616-e461-4d37-9451-063392c4b644)

Do not turn off power while flashing the firmware!


# 5 Troubleshooting

The collection of the problem elimination process.

## Changing Password

**i. Wi-Fi Password**

The default Wi-Fi network is turned on and without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

**ii. Router Password**

The default router password is `root` or `admin`. After accessing the router at **`http://192.168.20.1`**, go to `System` > `Administration`, you can change the router administration password.&#x20;

*\*The default router username is `root`.*

## Forget Router Password

The default login password is `root` or `admin`. If you have changed the router password and forgotten it, please reset the router to default settings. It will erase the previous configurations, and you can log in to the router again with the above default password.

## Wi-Fi SSID and Password

The Wi-Fi network is turned on by default. The default Wi-Fi SSID is `Cellular-WiFi-xxxxxx`. It's without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

## Disable Wi-Fi Network

To disable the Wi-Fi network, please access the router at `http://192.168.20.1`, go to `Network` > `Wireless`. You will enter the `Wireless Overview` page.

‌ There is only one radio section of `radio0`. The Wi-Fi hotspot created by the router is in the `mode` of **`Master.`** You can click the **`Disable`** button to turn off the Wi-Fi hotspot.

*\*If the Wi-Fi network is in the `mode` of `Client`, the Wi-Fi network is for the Wi-Fi relay connections.*

## Can Not Find Wi-Fi Hotspot

Please open the case of the EZR23 router and check the below indicators on the EZR23 router.

1. **System Indicator**<br>
   * If the system indicator is **off**, please check the connections of the power adapter and electric outlet.
   * If the system indicator is flashing, please wait 2-3 minutes until the router boot up.<br>

2. **Wi-Fi Indicator** - When the system indicator stays green, check the Wi-Fi indicator.<br>

   * If the Wi-Fi indicator stays green, the Wi-Fi network has been enabled, but no data is streaming on the Wi-Fi network.&#x20;
     * You can try to search for the Wi-Fi hotspot. Remember, you might have changed the Wi-Fi SSID name once before.
     * If you enabled the checkbox `Hide ESSID`, please input the Wi-Fi SSID name and password manually on the devices.<br>
   * If the Wi-Fi indicator is off and the Wi-Fi network has been disabled. Please access the router with the LAN cable connection and enable the Wi-Fi network.

3. If the above LAN cable connection does not work, you need to reset the router to default settings.

## Reset the Router

You can use either a soft reset or hard reset to erase the configurations on the router and back to the factory settings.

‌ The suggested way is a [**soft reset**](/manual/3-firmware/3.7-recovery#4-8-2-factory-reset). If unable to access the router, please do a [**hard reset**](/manual/3-firmware/3.7-recovery#ii-hard-reset) by clicking the reset button for 5 seconds when the router is turned on.

‌ If the hard reset does not work, please refer to [**EzBoot**](/manual/3-firmware/3.7-recovery#4-8-3-ezboot) to re-flash the firmware.
