The Reset Button*
Briefly pressing the Reset Button will refresh the Cable/DSL Firewall Router’s connections, potentially clearing any jammed links.
Pressing the Reset Button and holding it in for a few seconds will clear all of the Cable/DSL Firewall Router’s data. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Cable/DSL Firewall Router, you run the risk of creating conflicts between your PCs’ actual IP Addresses and what the Cable/DSL Firewall Router thinks their IP Addresses should be. You may be forced to reboot the entire system(s).
If the Cable/DSL Firewall Router locks up, simply power it down for three to five seconds by removing the power cable from the Cable/DSL Firewall Router’s Power Port. Leaving the power off for too long could result in the loss of network connections.

Link/Act Green. The Link/Act LED serves two purposes. If the LED is con- tinuously lit, the Router is successfully connected to a device through the corresponding port (1, 2, 3 or 4/DMZ). If the LED is flickering, the Router is actively sending or receiving data over that port.
Full/Col Green. The Full/Col LED also serves two purposes. If this LED is lit up continuously, the connection made through the correspon- ding port is running in Full Duplex mode. If the LED flickers, the connection is experiencing collisions. Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with your connection. See “Appendix A: Troubleshooting” if you encounter this problem.
100Orange. The 100 LED lights up when a successful 100Mbps con- nection is made through the corresponding port.
If this LED does not light up, then your connection speed is 10 Mbps.
