Can you buy you own modem for CenturyLink?

Yes you can! Because CenturyLink charges residential customers $10 a month to lease a modem, you can quickly make your money back by buying your own.

CenturyLink offers two types of internet access: DSL and fiber optic. If you are buying your own, make sure that your modem is compatible with your service. Cable modems will not work.

In theory, any modern DSL or fiber modem that supports the required technology features (ADSL, ADSL2+, VDSL2, GPON and Pair Bonding) should work, but it’s safest to stick with CenturyLink-approved routers. The full list is available, but the modems below are their top picks.

Modems are also known as gateways, and may also have dual functionality as a WiFi router. Please note that a router and modem aren’t the same thing. A modem provides connectivity to your internet service provider, while a router distributes that internet connection to the devices in your home over WiFi or ethernet.
