Frequently Asked Questions

Should I rent my modem from the ISP instead?

• We recommend buying over long term renting in most cases
• Renting fees are $10-15 monthly, which adds up over time
• Purchasing a quality modem pays for itself in under 1 year
• Then you own it and avoid all rental fees going forward

That said, renting does avoid upfront cost and makes replacement easy if something fails or technology changes. But brand name modems have excellent reliability and last 3 years on average. So you save more buying your own unless you move/change ISPs very frequently.

What is the difference between DOCSIS 3.0 and 3.1?

• DOCSIS refers to the technology standard used by cable internet providers
• DOCSIS 3.0 supports ~1 Gigabit speed
• DOCSIS 3.1 supports multi-gigabit above 1 Gbps
• Most homes don’t need over 1 Gbps capability currently
• But 3.1 future proofs your home for faster emerging plans

So while 3.0 covers nearly all households today, getting a 3.1 modem allows you to unlock the fastest fiber-like speeds as they roll out. It costs more but brings future-proof versatility.

Can I use my own modem if my provider supplies phone service?

• Yes, but you need a compatible voice/telephony modem
• These allow you to connect a phone line to make calls
• Double check your ISP supports voice service on third party modems
• Only certain Arris, Motorola and Netgear models may qualify

So verify voice capability if bundled home phone service before buying. The model numbers above don’t support telephony. But the provider can guide you in selecting an approved voice modem if needed.

What router should I use with my modem?

Any Wi-Fi router should work with a third party cable modem – just connect it to the modem’s ethernet port. We actually have an in-depth guide on finding the best routers here. Some things to look for include:

• Wi-Fi 6 – Latest standard for fastest wireless speeds
• Mesh Routers – Cover large homes with strong signal
• Gaming & Streaming Features – Improve latency & bandwidth
• Parental Controls – Manage kids device access
• Antivirus – Block malware and threats
• Range Extenders – Connect devices farther away

Mesh routers are ideal if have dead zones or buffering issues. A budget single router usually suffices for smaller spaces. Either way, pairing your modem with a quality router optimizes Wi-Fi coverage.

Can These Cable Modems Be Used With Any Internet Service Provider?

Yes, these cable modems can be used with any internet service provider. They are compatible with a wide range of ISPs, allowing you to enjoy lightning-fast internet speeds no matter who your provider is.

Are There Any Additional Fees or Charges Associated With Using These Cable Modems?

There aren’t any additional fees or charges associated with using these cable modems. You’ll only need to pay for the modem itself and your regular internet service provider fees.

Can These Cable Modems Be Used for Both Residential and Commercial Purposes?

Yes, these cable modems can be used for both residential and commercial purposes. They are versatile and offer lightning-fast internet speeds for all your needs, whether at home or in the office.

Do These Cable Modems Come With a Warranty or Guarantee?

Yes, these cable modems come with a warranty or guarantee. You can rest assured knowing that if anything goes wrong, you’ll be covered and can get a replacement or repair.
