Buying advice: routers

  1. Single routers suit apartments and compact homes. Mesh systems cover larger or multi-story homes and brick walls.
  2. Wi-Fi 6 is widely supported. 6E and 7 add the 6 GHz band, which is fast but shorter range.
  3. Connecting mesh nodes with Ethernet greatly improves speed if your home has wiring.
  4. Multi-gig ports matter for plans above 1 Gbps or fast home networks. Count LAN ports for consoles and PCs.
  5. Choose a brand with regular firmware updates. Change default passwords and enable WPA3 where devices support it.

No for most ISP connections. For cable internet: connect the modem to the new router's WAN port, reboot both, and the router receives a DHCP IP from the ISP automatically. For DSL or PPPoE connections (often fiber or some DSL setups): enter the PPPoE username and password in the router's WAN settings. You can find these in your ISP account or by calling ISP support.

Should I change the default router WiFi password?

Default WiFi passwords on most routers are printed on a sticker on the device itself, anyone who can see the router can connect to the network. Change the WiFi password and the router admin password during setup. Use a passphrase that is 12+ characters and not based on personal information.
