Most router advice starts with products and maximum speeds. It is easier the other way round: work out what limits your connection, then buy the router that removes that limit and nothing more. Answer these six questions in order:
- How fast is your internet plan? That decides the internet port your router needs.
- What Wi-Fi do your devices support? That decides which Wi-Fi generation is worth paying for.
- How big and how spread out is your home? That decides whether one router is enough.
- What equipment did your provider give you? That decides how the new router connects.
- How long will it get security updates? That decides how long it stays safe to use.
- Are you in the US? A 2026 FCC rule affects which new models can be authorized.
Each is explained below, followed by a checklist.
1. Start with your internet plan and the router’s internet port
A router can’t pass more internet speed than its internet (WAN) port allows. ISP guidance reflects this. gFiber, for example, recommends a router with a 1 Gbps WAN port and Wi-Fi 6 for its 1 Gig plan, and a 10 Gbps WAN port with Wi-Fi 6E or Wi-Fi 7 for its 2, 3 and 5 Gig plans.
Between 1 and 10 Gbps there are also “multi-gig” ports: 2.5 and 5 Gbps Ethernet, defined in the IEEE 802.3bz standard approved in 2016.
2. Match the Wi-Fi generation to your devices
A router’s Wi-Fi features only help devices that support them. The 6 GHz band, for example, is used only by Wi-Fi 6E and Wi-Fi 7 devices. Check what your phones, laptops and other main devices support before paying for a newer generation.

- Wi-Fi 6E vs Wi-Fi 7 helps if you’re deciding between the two newest.

3. Fit the router to your home
Coverage depends on your home, not on the router’s box. Lower Wi-Fi frequencies reach further, and 2.4 GHz has the longest range and best wall penetration of the three bands. The faster 5 GHz and 6 GHz bands cover less.
4. Check your provider’s equipment
If your provider supplied a gateway (a modem and router in one box), your new router will usually sit behind it. To avoid two routers in a row, the gateway’s router function should be turned off. Xfinity, for example, documents a Bridge Mode that does this, with trade-offs such as allowing only one device on the gateway.

5. Security features and update support
A router sits between your home and the internet, so how long it gets updates matters as much as its speed.
- Updates: CISA says routine updates protect against known vulnerabilities, and notes that some routers can install them automatically.
- End of support: devices that reach end of support no longer get security updates, and CISA urges replacing them.
- WPA3: WPA3 support has been required in all new Wi-Fi CERTIFIED devices since 2020. CISA advises using WPA3 Personal or WPA2 AES.

6. US buyers: the FCC’s 2026 router rule
On 23 March 2026 the FCC added “routers produced in a foreign country, except routers which have been granted a Conditional Approval” to its Covered List, and covered equipment can’t receive new FCC equipment authorizations. Routers authorized before they were added may keep receiving software and firmware updates that protect consumers at least until 1 January 2029.
The FCC router rule explained has the full timeline and current approval status by brand.
Subscriptions
Some routers sell security or parental-control features as a subscription. NETGEAR’s Armor, for example, is free for 30 days and then needs an annual subscription. If a feature matters to you, check whether it is included or ongoing.
The checklist
| Question | What to check |
|---|---|
| Internet plan | WAN port at least as fast as your plan (multi-gig if over 1 Gbps) |
| Wired devices | Enough LAN ports, multi-gig if you need fast wired speeds |
| Your devices | A Wi-Fi generation your devices support; 6E or 7 only if they use 6 GHz |
| Your home | One central router, or more access points or mesh for large or multi-floor homes |
| Provider equipment | Bridge mode on the gateway, or a router that plugs into your fiber terminal |
| Security | WPA3, automatic updates, a published update-support period |
| US regulatory status | FCC-authorized; Conditional Approval for new foreign-produced models |
| Subscriptions | Which features need an ongoing subscription |
Once you’ve answered these, you know what to look for in any product listing.
