Gigabit packages can reach speeds beyond 1Gbps, meaning connecting your new modem to a router requires some careful consideration. Some of the best Wi-Fi 6 routers offer 2.5G WAN ports and support link aggregation. Be sure to match your modem to a compatible router like the TP-Link Archer GX90 to take full advantage of the fastest Gigabit speeds.

As the best overall modem, the SURFboard SB8200 is compatible with speeds up to 2Gbps using two Ethernet cables in tandem via aggregation or 1Gbps with just one. If you're signing up for a voice package using VoIP, you'll need a modem with RJ11 telephone ports like the ARRIS SURFboard T25 to connect your phone line. Whatever you decide, these modems are yours to keep forever, circumventing hardware rental fees.
