1.4 Troubleshooting
Avoid IP address conflicts
The USB dongles have a static IP address within a predefined IP address range. It
is not possible to change the IP address of the dongle. Make sure to avoid an IP
address conflict with the IP address assigned to WAN or LAN port.
Examples:
Huawei
Alcatel
Dongle IP address
192.168.8.xxx
192.168.1.xxx
Default gateway
192.168.8.1
192.168.1.1
Use 4G dongle for troubleshooting
In case of any network issues in WAN networks, it is recommended to set up a
temporary cloud connection with a 4G dongle for troubleshooting.
An automatic switch from WAN to WWAN interface is internally used for mobile
internet connection via 4G dongle. To ensure a temporary connection via one of
the supported 4G dongles, you must disable the proxy.
1. Go to Network > Proxy.
2. Disable Proxy.
3. Click Save.
4. Reboot the Connect X300 device.
After unplugging the USB dongle, make sure the proxy is enabled again in case
the device is operating via default WAN interface.
