How to Fix The 2Wire 2700HG "Limited or No Connectivity"
Version 0.513

This article explains how to fix your 2Wire 2700HG router given by Singnet (a Singapore ISP) if it gets stuck with the Ethernet and Power light solid on. Many other Internet Service Proivders (ISPs) around the globe use this gateway router as well.

ANOTHER COMMON ISSUE: If your modem keeps restarting once the power LED turns solid green, the most likely cause is the power adaptor. Replace the power adaptor and all should be well again.

Symptoms

This problem occurs when you set WPA encryption on the router with a password, and then disable the wireless feature. The router behaves normally, but when you attempt to do a restart or power off/on, the DSL light refuses to come on.

Any wired PC will start reporting a "Limited or No Connectivity error". The router stays with the Power light and Ethernet light solid on.

Hitting the reset button restarts the router with the same result.

How to Fix (getting it to start up properly)

The fix is actually very simple. Most people would wait for some time before hitting the reset button. The trick here is to hit the button once the power light comes to solid green.

1. Disconnect running ethernet devices.
2. Switch on the router.
3. Once the power light is solid on, QUICKLY press and hold the reset button until it restarts.

That's it. With luck, the DSL light will come on after it restarts. You will need to reconfigure your login and, if needed. port forwarding.

Is this a software bug in Singnet's (Singapore ISP) 2700hg Firmware?

Apparently, yes. This thread has more information.
