Even the best router can’t fix a weak connection coming into the house. This category covers everything between your internet provider and your own network, from choosing a type of service to understanding the box on the wall and getting back online when it stops working.
Choosing a connection type
Most US homes can choose from some combination of fiber, cable, 5G home internet and satellite service, but availability differs a lot from one address to the next.
Fiber and cable
Fiber usually offers matching upload and download speeds and low latency, while cable is widely available and often fast but typically has slower uploads. We compare them in terms that matter for remote work, gaming and streaming, and explain what a fiber installation usually involves.
5G home internet and satellite
5G home internet and low-earth-orbit satellite service can be good options where wired service is limited, but they come with their own trade-offs in consistency, latency and placement. We explain those trade-offs plainly and help you decide whether they fit how you use the internet.
Modems, gateways and ONTs
The equipment your provider supplies may be a modem, a gateway that combines a modem and router, or an optical network terminal for fiber.
Modem vs. router and combo units
We explain what each device does, when a combo unit makes sense, and when separate equipment gives you more control. We also cover how to replace a rented modem with one you own, and why checking your provider’s approved device list is essential.
Bridge mode and status lights
Bridge mode lets your own router take over from an ISP gateway, and getting it right avoids double NAT and confusing network problems. We also explain what common status-light colors and blinking patterns usually mean, and when they point to a provider-side problem.
Speed needs and troubleshooting
More speed isn’t always the answer. We help you work out what your household needs for video calls, streaming, gaming and uploads. We also walk through practical troubleshooting for problems like being connected without internet, DNS errors, slowdowns at night and one device that won’t connect.
Backup internet and travel connectivity
If you work from home, an outage can cost you more than an evening of streaming. We cover backup internet options, failover setups and travel routers, including how to get through hotel login pages.
Check with your provider
ISP rules, compatible equipment lists, plan terms and installation practices vary by provider and change over time. Use our guides to understand your options, then confirm the specifics with your provider before you buy equipment or switch plans.
