Yesterday evening, when I got back from vacation, I found that our home internet connection and phones weren’t working. Our ISP is Ziggo, and when I called them they agreed with my initial assessment that the modem wasn’t working. They found a local retailer that could provide further service, so I went there.
I put the modem – a Ubee EVM 3200 – and its power adapter on the counter, and told them that one of the two items was probably faulty. Immediately, they said it was the power “brick”, and offered a free replacement. From what they told me, the original 12V 1A adapter was too weak for the modem, and they were failing for many customers. I got a 2A replacement, and was soon back online.
With the old adapter, my modem would seem to power on, but all the lights would come on at once, and they’d flicker slightly. Normally, the modem requires some time to power up, and the lights are steady. If your modem is acting up, you might want to call Ziggo to get the power plug replaced.
Kudos to Ziggo for handling all this very smoothly btw, and shame on Ubee for supplying the underspecced original ac adapter.
