Appendix A - Troubleshooting 

Server is Disabled. 

In this situation, the DHCP Server must still allocate an IP Address to the 
Dial-in user. To set this IP Address: 
1.  Connect to the LevelOne WBR-1101TX 
2. On 

the 

Quick Setup

 screen, locate the DHCP Server section, and set 

both the 

Start IP Address

 and the 

Finish IP Address

 to the IP Address 

you wish to be assigned to the Dial-in user. 

3.  Save these settings.
