No internet connection - troubleshooting guide

Eircom Netopia modems 2247 (silver one) are very easy to troubleshoot.

1.First check DSL sync light on the front of the modem, should be constant ON green. This is your modem synchronization with the port at local exchange. If that that light is on, means no hardware faults with DSL frequency on the line. It is possible you might have problem with calls, like noise on the line or no dial tone and DSL light will be on, and another way around.

2.If it's on check 'internet' light (if it's not see below 'no sync' section on the forum) should be solid or flashing green. Internet light is PPPoE authentication light, when is connected it will be green, so if both light are on, and your internet doesn't work, I would rather check PC or/and LAN connections.

If 'internet' light is red or off follow the procedure in 'PPPoE problems' section in the forum.

Eircom Netopia modems are preconfigured for broadband, so you can reset it without any problems, only thing you have to worry is if you had changed default settings on it for your LAN requirements.

Those modem are low range price modems, so you might need to reset it, it is standard procedure when you will call help desk. So do it yourself and you will safe yourself some time on the phone.
