Things to consider when choosing Suddenlink modems

If you use the Suddenlink modem then you will receive technical support and an equipment replacement if a malfunction occurs or if you need to upgrade the cable modem.

Some consumers however prefer to use their own cable modem as this gives them the flexibility to get the features that they want as well as save on the monthly modem rental fees.

There is no longer any Suddenlink certified modem list as the company no longer maintains an official list. The company however states that as long as the modem is DOCSIS 3.0 or DOCSIS 3.1 then it should work with their network.

When choosing your own modem you should consider the speed of your subscription. different internet plans will have different internet speeds. Some modems might not handle the high speed internet of your service.

Instead of enjoying your 1Gbps speed the modem that you get might only be able to give you 600 Mbps speed.

If you can’t decide on getting a modem or combo modem with a built in wireless router then consider getting the modem instead since you can always buy a standalone router in case you need it in the future.
