Buying Guide
What to Look For
Ensure your chosen modem supports DOCSIS 3.1 for gigabit speeds. Check for multiple Ethernet ports if wired connections are needed, and verify compatibility with your ISP. Future-proofing with advanced standards and features like IPv6 can also be beneficial.
Common Mistakes to Avoid
Avoid purchasing a modem with lower DOCSIS standards like 3.0 for gigabit plans, as it limits speeds. Also, don’t forget to confirm your ISP’s compatibility, and steer clear of models with no warranty or poor reviews.
Additional Tips
Consider buying a modem-router combo if you prefer fewer devices, but for maximum performance, separate modem and router setups are often better. Keep in mind that investing in a quality router can significantly enhance your overall internet experience.
FAQs
Can I use any cable modem for gigabit internet?
No, only models supporting DOCSIS 3.1 or high-end DOCSIS 3.0 standards can handle gigabit speeds effectively.
Do I need a separate router with these modems?
If the modem doesn’t have built-in Wi-Fi, you’ll need a separate router to access wireless internet; many models do include integrated Wi-Fi.
