Chapter 11. Trouble Shooting

11.1 Internet connection

Symptom: Yo u can n o t access th e ro uter’s web -configuration interface from a PC on

your LAN.

Recommended action:

1. Check the Ethernet connection between the PC and the router.

2. Ensure that your PC’s IP address is on the same subnet as the router. If you are using the

recommended addressing scheme, your PC’s address should be in the range 192.168.1 0.2

to 192.168.10.254.

3. Check your PC’s IP address. If the PC cannot reach a DHCP server, some versions of

Windows and Mac OS generate and assign an IP address. These auto-generated addresses

are in the range 169.254.x.x. If your IP address is in this range, check the connection from

the PC to the firewall and reboot your PC.

4. If your router’s IP address has changed and you don’t know what it is, reset the router

configuration to factory defaults (this sets the firewall’s IP address to 192.168.10.1).

5. If you do not want to reset to factory default settings and lose your configuration, reboot

the router and use a packet sniffer (such as Ethereal™) to capture packets sent during the

reboot. Look at the Address Resolution Protocol (ARP) packets to locate the router’s LAN

interface address.

6. Launch your browser and ensure that Java, JavaScript, or ActiveX is enabled. If you are

using Internet Explorer, click Refresh to ensure that the Java applet is loaded. Close the

browser and launch it again.

7. Ensure that you are using the correct login information. The factory default login name is

admin and the password is password. Ensure that CAPS LOCK is off when entering this

information.

Symptom: Router does not s ave configuration changes.

Recommended action:

1. When entering configuration settings, click Apply before moving to another menu or tab;

otherwise your changes are lost.

2. Click Refresh or Reload in the browser. Your changes may have been made, but the

browser may be caching the old configuration.
