FAQ:

Q: How to set up a Motorola surfboard modem?

A: Uptime: This is how long your modem has been powered on. CM Status: This is your Cable Modem status. A working cable modem should display OPERATIONAL. SNR (Signal to Noise Ratio): This is how much interference your signal has. The higher the reading the better,and it should be above 25-27. Power: This is a measurement of the incoming signal strength. …

Q: Which is the best cable modem?

A: – Write down your cable modem’s serial number and MAC address first. … – Return a rented cable modem to your ISP in person and get a receipt. … – Check the grade of any included Ethernet cable. Not all network cables are created equal, and sometimes the one that comes with hardware isn’t fast enough. …

Q: Should you buy your own cable modem?

A: You should rent a modem or router (or both) from your internet provider if you want upgrades, replacements, and technical support at no additional cost to you. If you want to save money over the long run and have more control over your internet connection, buy your own router.

Q: Do I have a bad cable modem?

A: When a cable modem is bad, check all cables when you’re diagnosing a modem. Replacing any cord is far better than having to get an entirely new modem. If the cables are not the problem, maybe the cable modem is bad or part of the problem. Another area you’ll want to check is the device itself.
