Worked great a few weeks until our internet service started flickering on and off every few minutes for several days. I strongly suspect being turned on and off 50+ times a days effected it’s like span.
This finally killed our modem.
I asked for refund and was offered a choice of a replacement or refund.
RECEIVED REPLACEMENT immediately! No delays no problem.
Good folks, keep their word.

Worked with Centurylink
The product works great to connect to CenturyLink. My CenturyLink was out and of course the ISP blamed my hardware and not their service. So I ordered this as a backup unit to test my connection. After 12 days of outage my signal came back from the provider and both my DSL modems worked - my original and this one. To test this modem I hooked it up to my service and did not have to do anything! It just worked. I did a speed test and confirmed internet access. I have no reason to keep it, as the problem turned out to be my ISP’s problem. I would buy one of these in an instant if my current DSL modem actually failed.
