Linovision gateways provide multiple backhauls for network connection. Here are the symptoms about failing to access the network via Wi-Fi, Ethernet or cellular.

Symptom 1: Can not access the network via Wi-Fi.
Checklist:
Check if Wi-Fi status shows connected and gateway is assigned an IP by your Wi-Fi router.

1. If not, check if Wi-Fi configuration is correct.
2. If yes,

• Change the main link to WLAN;
  
• Connect a PC or mobile phone to the Wi-Fi access point to check if it works;
• Connect gateway to another Wi-Fi access point.

Symptom 2: Can not access the network via Ethernet Static IP mode.

Checklist:
Go to Maintenance-> Tool -> Ping to ping both www.google.com and 8.8.8.8 to check connection.

1. If only 8.8.8.8 works, go to Network -> Interface -> Port to check whether DNS server is configured. DNS server is used for resolving domain name to IP address.
   
2. If both not work,

• Check if Port setting is correct.
• Check if the IP address you type has been used by other devices.
• Change the main link to eth0/GE0.
  

Symptom 3: Can not access the network via cellular.

Checklist:
1. Check if your SIM card can use in other devices (smartphone, etc.).
2. Ensure you type the correct APN; username, password, PIN code and Roaming are necessary according to your SIM card type.

3. If you use private SIM card, delete or change a private network ICMP server.
