D. Go to “Network > Interface > Link Failover” to rise the WAN priority to 1.
E. Open your preferred browser on PC, then type any available web address into address bar and see if it is able to visit Internet via R75 router.
Cellular Connection Configuration
Take inserting SIM card into SIM1 slot as an example; please refer to the following detailed operations.
A. Click “Network > Interface > Cellular > Cellular Setting” to configure the cellular info, like APN and network type.
B. Click “Save” and “Apply” for configuration to take effect.
If you select “Auto”, the router will obtain ISP information from SIM card to set APN, Username, and Password automatically. This option will only be taken effect when the SIM card is issued from a well-known ISP.
C. Go to “Network > Interface > Link Failover” to enable SIM1 and rise link priority of SIM1.
D. Click 
to configure ICMP ping detection information.
E. Click “Status > Cellular” to view the status of the cellular connection. If it shows “Connected”, it means SIM1 has dialed up successfully. On the other hand, you can check the status of SIM indicator. If it keeps on green light statically, it means SIM1 has dialed up successfully.
