Troubleshooting 3801HGV Gateway
What to Do
• Check the Ethernet cable connection on the computer
and gateway, and make sure that it is securely seated in
both ports
• Check the ETHERNET indicator on the gateway; it
should blink green
Navigate to Settings > LAN > Wired Interfaces. Select
the appropriate mode from the Port Mode drop-down
list box. Auto-detect is the recommended mode for
configuring Local Ethernet connection.
Navigate to Settings > LAN > DHCP. Select the DHCP
Server Enabled check box for enabling the gateway to
assign IP addresses to the LAN clients automatically.
If the LAN computer has static IP configured, ensure
that DHCP IP addressing on the gateway is not
assigning an identical IP address. Change the DHCP
server IP addressing range and try assigning a different
static IP address to the LAN computers.
If the issue persists, then configure DHCP on the LAN
computer to obtain the IP address automatically.
Check with your ISP for activating IPTV services.
Select the HomePNA Networking check box from
Settings > LAN > Wired Interfaces.
Navigate to Settings > LAN > Wireless. Select the
SSID Broadcast check box in the Network section.
Navigate to Settings > LAN > Wireless. Select the
Enable Wireless Interface checkbox.
Ensure that you select the relevant authentication type
for configuring your wireless client.
Ensure that the wireless mode on the wireless client is
compatible to the wireless mode on the gateway.
Ensure that your wireless client is within the wireless
range of the gateway.
Change the Power Setting value to increase the signal
strength.
Change the Wireless Channel value. Alternatively, you
can also change the Wireless Channel Mode to auto.
Configure the custom encryption key in a way that it
conforms to the security mode, key length, key type, or
value type.
Navigate to Settings > LAN > IP Address Allocation.
Browse to the LAN client where access is restricted.
Select Disabled from the Firewall drop-down list box.
