User manual

Sometimes errors can cause your browser, email application, or DSL modem to stop

responding or lose their connection to the Internet, even though the connection is still

present and active, and even though the computer or application may look like they're

still running correctly. Since errors of these types are the single most common cause of

loss of connectivity, it is usually best to start by rebooting these devices to rule them out

first thing:

1. Reboot your computer by shutting it down as you normally would, and then

restarting it.

2. Reboot the DSL modem by switching the power switch to the "off" position,

waiting 3-5 seconds, then returning the switch to the "on" position. In most cases,

the power switch will be found on the back of the device, usually on the same

face as the ports for the DSL line and network connection. Please refer to the

hardware documentation for more detail.

3. If you connect via any sort of intermediary device, such as a hub

, router, proxy

computer, hardware-based firewall

etc, then you will want to reboot these

devices as well, in case a problem with them is interrupting your connection to

the Internet.

Step 2: Status of the lights on the DSL modem

The lights on the face of your DSL modem can help provide you with some insight into

the cause of your outage. The lights you want to pay particular attention to are the ones

indicating the connection from the device to the local network (often labeled as "ENET"

or "LAN") and the ones indicating the connection from the device to the DSL equipment

at your Central Office, (often labeled as "DSL" or "WAN"). The labels of the indicator

lights will vary from one modem make/model to another, so the labels indicated above,

while appropriate for most models may not apply to your modem. If in doubt, please refer

to your modem documentation. This is a basic guide to what specific and common light

statuses might mean:

 On most DSL modems, a red light or no light at all indicates a problem.

 An outage on the local network side, ENET or LAN, indicates that there is a

problem with the physical connection itself between the DSL modem and your

network or your computer (see Step 3 below). If your modem has both "LAN10"

and "LAN100"; lights, only one would be lit in normal circumstances.

 An outage on the DSL side, DSL or WAN, indicates that the DSL modem cannot

connect to the DSL hardware in your Central Office (CO). This could indicate

either a problem with the CO hardware, or simply a loose connection between

your DSL modem and the wall-jack (see Step 3

below)

Step 3: Check your IP configuration
