Quick Tips

This section describes tips for troubleshooting some common problems.

Sequence to Restart Your Network

Be sure to restart your network in this sequence:
1. Turn off and unplug the modem.
2. Turn off the wireless modem router and computers.
3. Plug in the modem and turn it on. Wait 2 minutes.
4. Turn on the wireless modem router and wait 2 minutes.
5. Turn on the computers.

Check Ethernet Cable Connections

Make sure that the Ethernet cables are securely plugged in.
• The Internet status LED on the wireless modem router is lit if the Ethernet cable
connecting the wireless modem router and the modem is plugged in securely and the
modem and wireless modem router are turned on.
• For each powered-on computer connected to the wireless modem router by an Ethernet
cable, the corresponding numbered router LAN port LED is lit.

Wireless Settings

Make sure that the wireless settings in the computer and wireless modem router match
exactly.
• For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the wireless modem router and wireless computer need to match
exactly.
• If you set up an access list in the Advanced Wireless Settings screen, you have to add
each wireless computer's MAC address to the wireless modem router's access list.

Network Settings

Make sure that the network settings of the computer are correct.
• Wired and wirelessly connected computers need to have network (IP) addresses on the
same network as the wireless modem router. The simplest way to achieve this address
commonality is to configure each computer to obtain an IP address automatically using
DHCP.
