Swapping the modem
Swapping the modem
You can likely replace the modem yourself. You can purchase a modem from various online stores or local electronics shops. Keep in mind the compatibility with your internet service and follow proper installation steps to ensure everything works correctly.
Ask for the model and make of the modem provided by your internet service provider.
Consult your internet service provider to learn about their technology. They should provide a catalog of tested and supported modems on their support page. Modems absent from that list may function technically, but your ISP might not enable them within their network. If you receive phone service, ensure your modem supports voice functionality. Proceed cautiously when purchasing used modems; they could remain linked to the previous account and won't be deactivated without the former user releasing them in the ISP's system. When receiving TV service from your internet provider, verify that your set-top boxes don't depend on your ISP's gateway for features such as schedule updates and video on demand.
Verify with your ISP as they are increasingly restricting this due to the time spent troubleshooting customer modems, despite their reliability. A technician mentioned he must frequently take calls because customers opt for the cheapest modem, not realizing it won't support higher speeds and leads to service issues. If you're considering it, it might be worth it—especially with your Motorola Surfboards—but you should weigh the cost against your needs.
Many providers bill you between $10 and $15 monthly for a "rental" that lets you save enough to cover the modem you purchased. The same applies to cable boxes—you only pay for a rental when you get your hdhomerun Prime, which includes free DVR service instead of another $10 to $15 for a separate box, plus extra fees for any additional boxes.
I haven't verified if my ISP includes the modem in my monthly charges (though I do review the overall cost breakdown). They clearly put a lot of effort into supporting them. The setup features four gigabit LAN ports, wireless AC with decent coverage, and they replace broken units easily by taking them out and ordering new ones. Many people express frustration about 'rented' modems—maybe my ISP is the only one committed to backing their leased devices, or perhaps I’m just the one who prefers dealing with the ISP when things go wrong.
I've purchased my modem and experienced fewer problems with my internet connection. This means I spend less time contacting my cable provider. Upgrading my modem is now uncommon; I only changed it once over the past decade to enable DOCSIS 3.1, which offers more channels than my earlier model.
over the last decade I've mainly had to replace it because of serious grid instability, which causes the power supply to degrade much faster and leads to inconsistent performance. the new specifications are a welcome improvement. without a power filter I'd be constantly replacing consumer-grade routers, so I'm satisfied with a comprehensive warranty plan for my modem.
Across the country our electricity looks quite stable, I haven’t faced any problems with router burnouts or other gadgets (except for occasional lightning strikes). I still use an older WRT-54G model to extend Wi-Fi coverage inside my home.
