I bought this to replace the equipment from Centurylink. I was having issues with my internet but they are the only provider in my area so I decided to try new equipment. All of my issues are gone. My internet is faster. No buffering. We have at least four devices on wifi constantly and have no issues now. I got this modem for $50 and a Netgear router for $45 and it was money well spent. The setup was easy breezy too.
