6. Use the dhcp-server command to verify the LAN’s DHCP server is set up correctly. The
gateway field should be set to the LAN’s IP address, and the ip-address-start and ip-address-
end fields should be within the subnet configured for the LAN port. For example, suppose the
LAN is configured with the IP address 192.168.1.1 and subnet 255.255.255.0. If DHCP server 1
was used to service the LAN, its configuration should look something like this:
digi.router> dhcp-server 1
dns1 192.168.1.1
dns2
gateway 192.168.1.1
ip-address-end 192.168.1.199
ip-address-start 192.168.1.100
lease-time 1440
mask 255.255.255.0
state on
7. Verify that the PC or device plugged into that port has been configured to use DHCP to get an
IP address.
8. If the PC still cannot communicate with the Ethernet port, try plugging a different PC into the
port and see if that can communicate over the port. If it can, the problem is with the first PC or
device.
9. Enter the show dhcp command to verify that there are some available DHCP leases left. For
example, the DHCP server configuration creates a range of 100 DHCP leases, and the DHCP
status below shows that only one is in use. If your status showed that all available DHCP leases
were in use, you would have to either update the DHCP server configuration to add more
leases, or remove some devices from the LAN.
digi.router> show dhcp

10. If you still have communications issues with the LAN port, contact Digi Technical Support.
Verify cellular connectivity
Test SIM slot
1. With the router powered off, insert a SIM card into the SIM 1 (LR models) or 1-1 (WR models)
slot of the TransPort device.
