Proxicast EtherLINQ User manual

4G LTE Router + WiFi + VPN
Quick Start Guide
The REALLY QUICK Start Guide
1. Attach the external antennas
2. Insert an activated SIM
3. Connect power to the EtherLINQ
4. Wait 90 sec. for the OS and LTE LEDs to stop flashing
5. Connect a DHCP-enabled PC to the LAN port or scan for a WiFi network named
EtherLINQ-xxxx and enter the 8 digit password printed on the EtherLINQ’s label
The EtherLINQ automatically attempts to connect to the default APN for your 4G carrier.
If you are using a different APN or the modem fails to connect to the Internet:
•Browse to http://192.168.1.1:8080 Username/Password: admin/1234
•Select the LTE tab
•Enter the correct APN for your SIM
•Click the Save & Apply button
•The EtherLINQ will reboot and connect to the Internet
Click the “Check For Updates” button to install the latest firmware

Troubleshooting
PROBLEM
CORRECTIVE ACTION
None of the LEDs
turn on Ensure that the correct power adapter is connected to the EtherLINQ and plugged in to an appropriate power source. If
the LEDs still do not turn on, there may be a hardware failure.
Cannot access the
EtherLINQ from a
PC on the LAN
Check the cable between the computer (or hub/switch) and the
EtherLINQ. Check that the corresponding LAN port LED is ON.
Configure the PC to receive its IP settings via DHCP
(automatic assignment).
Confirm that any other network interfaces on the PC (such as
WiFi) are disabled.
Cannot ping the
EtherLINQ from
the LAN
If the LAN LEDs are off, check the cable connections.
Verify that the IP address and subnet of the EtherLINQ is in the
same range as the computers on the LAN and that the
EtherLINQ is the default gateway for all LAN devices.
Cannot make (or
maintain) a
cellular data
connection
(i.e. no LTE WAN
IP address)
Confirm that the SIM has been provisioned & activated with the
correct type of Internet access data service.
Ensure that the SIM/RUIM card (if required) is properly
inserted.
Network registration may take several minutes.
Cellular Signal
Quality is low Connections may be unreliable if the signal quality is < 33%.
Check that the proper external antenna is securely attached.
Use coax extension cables to locate the antennas to a more
favorable location.
Move the EtherLINQ to a location where the carrier’s signal is
stronger or use a higher-gain antenna or amplifier.
Cannot get a
WAN IP address
from the Ethernet
WAN ISP
The WAN IP address may not be provided until after the ISP
verifies the MAC address. Confirm the verification method used
by the ISP.
Check the EtherLINQ’s connection to the wired WAN
(cable/DSL modem). Check whether the Ethernet WAN
connection requires a crossover or straight cable.
After pressing
RESET, cannot
make a WAN
connection
The RESET button returns the EtherLINQ to its factory default
settings including clearing the LTE APN and WAN parameters.

Common Carrier-Specific Issues
CARRIER
COMMENT
Verizon
Wireless 4G/LTE Verizon Wireless’ default APN (vzwinternet) provides only NAT’d
IP addresses. This prevents all Internet initiated inbound (remote
access) connections from reaching the EtherLINQ.
Use the EtherLINQ’s VPN features to make an outbound
connection to a VPN server on another network; or
Purchase a static public IP address from Verizon for an
additional fee.
AT&T Wireless AT&T’s default APN (broadband) blocks all packets originating
from the Internet. To access the EtherLINQ or other equipment
remotely, request that AT&T provide you access to the i2gold
APN or another APN which offers mobile terminated data service;
Or use the EtherLINQ’s VPN features to make an outbound
connection to a VPN server on another network; or
Purchase a static public IP address from AT&T for an
additional fee.
