Troubleshooting 

I cannot access the

LAN.  

If the 10M/100M LEDs on the front panel are both off, refer to Chart A-2 Troubleshooting 
the LAN LED. 

Make sure that the IP address and the subnet mask of the Prestige and your 
computer(s) are on the same subnet. 

I cannot ping any 
computer on the LAN. 

If the 10M/100M LEDs on the front panel are both off, refer to Chart A-2 Troubleshooting

The ISP provides the WAN IP address after authenticating you. Authentication may be 
through the user name and password, the MAC address or the host name.

address from the ISP. 

The username and password apply to PPPoE and PPoA encapsulation only. Make sure

If you use PPPoE pass through, make sure that bridge is turned on. See the Menu 1 General 
Setup chapter for details. 

For wireless stations, check that both the Prestige and wireless station(s) are using the same 
ESSID, channel and WEP keys (if WEP encryption is activated).

Check the schedule rules. Refer to the Call Scheduling chapter (SMT).
