# Troubleshooting

## 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](https://outdoor.router.works/ezr33/configuration/wi-fi-hotspot#iii.-wi-fi-ssid-and-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://192.168.30.1`**, go to `System` > `Administration`, you can change the router administration password. 

*\*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](#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 `Outdoor-WiFi-xxxxxx`. It's without the encryption password. You can refer to [Wi-Fi SSID & Password](#wi-fi-ssid-and-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://192.168.30.1`, 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*](https://outdoor.router.works/ezr33/configuration/wi-fi-hotspot#wi-fi-relay) *connections.*

## Can Not Find Wi-Fi Hotspot

Please open the case of the EZR33 router and check the below indicators on the EZR33 router.

1. **System Indicator**<br>
   * If the system indicator is **off**, please check connections to the PoE adapter, the green light on the PoE adapter should stay green when it's continuously providing power to the router.<br>

     * If the indicator on the [PoE adapter](https://outdoor.router.works/ezr33/diagnostics/broken-reference) is off or flashes, try another electrical output socket and replug the connections on the [PoE base socket](https://outdoor.router.works/ezr33/installation/poe-and-lan).

   * 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 there is no data 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](#wi-fi-ssid-and-password) once before.
     * If you were enabled the checkbox [`Hide ESSID`](#wi-fi-ssid-and-password), 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](https://outdoor.router.works/ezr33/installation/poe-and-lan) and enable the [Wi-Fi network](https://outdoor.router.works/ezr33/configuration/wi-fi-hotspot).

3. If the above LAN cable connection does not work, you need to [reset the router](#reset-the-router) to default settings.

## No 4G Connections

Firstly, please refer to the [Internet & IP](https://outdoor.router.works/ezr33/diagnostics/internet-and-ip) and check if the router already has an internet connection on the mobile modem. If there are no 4G connections, please check the below subjects.<br>

* Verify SIM Card Installation
  * [Recheck your SIM card](https://outdoor.router.works/ezr33/diagnostics/verify-sim-card)
  * [Check SIM status and registration on the router](https://outdoor.router.works/ezr33/verify-sim-card#i.-sim-ready)&#x20;
* Verify 4G Signal Strength
  * [Find a location](https://outdoor.router.works/ezr33/installation/signal-tests#find-a-location) with stable 4G LTE signal reception
  * [Test signal strength on the router](https://outdoor.router.works/ezr33/diagnostics/test-signal-strength)
* Check Modem Connection
  * Check both the [physical connections](https://outdoor.router.works/ezr33/modem-connection#physical-connections) and [virtual interfaces](https://outdoor.router.works/ezr33/modem-connection#virtual-interfaces)

After checked and fixed the issues mentioned on the above subjects, but still have the 4G connection problem, please log in to the router, go to `Status` > **`System Log`**. Copy the system log and :link: [send it to us](https://www.outdoorrouter.com/contacts).

## Slow Speed on 4G

The 4G cellular router relies on the 4G signal to set up an internet connection. Make sure you install the router which has a [strong 4G signal reception](https://outdoor.router.works/ezr33/installation/signal-tests). If the signal reception is very weak, please refer to [Improve Weak Signal](https://outdoor.router.works/ezr33/installation/signal-tests/improve-weak-signal).

## Reset the Router

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

‌ The suggested way is a [**soft reset**](https://outdoor.router.works/ezr33/configuration/recovery#i.-soft-factory-reset). If unable to access the router, please do a [**hard reset**](https://outdoor.router.works/ezr33/configuration/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**](https://outdoor.router.works/ezr33/configuration/recovery#ezboot-1) to reflash the firmware.
