Summary: D-Link DSL-2540B This modem worked flawlessly since the first day I bought it. Suddenly, for no apparent reason, it stopped working. I tried power off/on the modem many times. The power lights came up ok but the computer wouldn't get a signal.
Summary: Poor perfomance on Centurylink network compared to any of the provided DSL modems. Quality was decent, but had to replace 1 DOA, and another under warranty. A couple of these were dead after 2 years and throw aways. I no longer buy anything from D-Link.
