Configuring Ethernet Connections
An "Ethernet" Connection should be used if you either attach the ABS to an internal LAN (via a hub, switch, router) or whenever you connect the ABS directly to a cable or DSL modem. Your ISP should be able to provide you with all the answers you need.
- Set up "Configure TCP/IP:"
- If you are using a cable modem or DSL line, chances are that "Using DHCP" is ideal.
- If your ISP requires a manual configuration, you can select "Manual" instead and enter all the information that your ISP provided to you. This is quite a bit of work and it is imperative that all numbers and points are entered correctly. Otherwise, you are going to be very, very frustrated.
- If you're having frequent issues with flaky internet connections, your base station may be interacting badly with the high-speed modem. Usually, it's a problem that manifests itself with Domain Name Servers (I describe what DNS servers do in a bit more detail on my Drop-Outs Troubleshooting page). If the Domain Name Server (DNS) information is not passed properly between the modem and the base station you'll get frequent messages from your web-browser to the effect of Safari can't find page "http://www.xyz.com/abc.html" because it can't find the server "www.xyz.com".
If this is the case, simply copy the gray IP numbers to the right of the DNS Server fields exactly as shown into the open fields. Be very careful to get this step right... the IP numbers should consist of four sets of digits separated by dots, like "126.96.36.199", as a random example. Enter two different IP addresses for the DNS servers to ensure that if one fails that the other can pick up the load.
If the IP addresses are not listed next to the entry field, call up your ISP to get the information from them or look at your contract (sometimes, the DNS server IP addresses are listed there).
Note: By manually entering IP addresses for the DNS servers, you may experience service issues if the ISP changes the addresses of its DNS servers (typically, this is very rare). On the other hand, entering the DNS addresses can dramatically speed up your browser and may make it more adept at finding the servers you're looking for. I enabled it on my base station because RCN's cable modem misbehaves from time to time and have not had any issues with my browser since then.
- At the bottom of the screen, the admin utility also allows you to enter a Domain name and DHCP client ID, which your ISP would give to you if it was necessary. Otherwise, just leave the fields blank.
