ARRIS Surfboard G34

If you’re looking to streamline your setup and avoid purchasing separate devices, the Arris Surfboard G34 is an outstanding investment, particularly if you’re sticking with TDS’s high-end Gigabit plan. The G34 offers the best of both worlds by combining DOCSIS 3.1 networking technology with Wi-Fi 6 standard, surpassing its predecessor in terms of speed, coverage, and overall performance.


With its stacked feature set and dual-band Wi-Fi 6 support, the G34 boasts a maximum throughput capacity of 3000 Mbps, with individual band speeds as follows:

  • 5 GHz: 2401 Mbps
  • 2.4 GHz: 574 Mbps

This modem-router combo allows you to pair it with any plan up to or below 1 Gbps, thanks to its 32 x 8 channel bonding that caters to your high-speed requirements with plenty of free channels for data transmission. It is also backward compatible, ensuring compatibility with lower speed plans.

To gauge real-life performance, I paired the G34 with a TDS 1 Gbps plan and measured net download and upload speeds on my iPhone 13. The device delivered impressive speeds of 903 Mbps for downloads and 76 Mbps for uploads, making it an attractive choice for gamers and avid movie-watchers. The inclusion of MU-MIMO technology and powerful hardware contribute to its stable and lag-free performance.

WiFi Coverage & Device Capacity:

As a modem-router combo, I didn’t have high expectations for its coverage. However, I was pleasantly surprised by its stated coverage of 3,000 square feet. I installed it in a client’s space with multiple thick walls and an additional router. Despite these obstacles, it managed to provide coverage for an area of up to 2,500 square feet, which is equivalent to a mid-sized three-bedroom apartment or a decent-sized workspace.

The presence of MU-MIMO technology ensures efficient handling of multiple devices simultaneously. I observed that up to 25 devices could connect to the G34, with signals being transmitted at equal strength, enabling smooth streaming of UHD content on each connected device.

Ports & Connectivity:

The G34 offers four Ethernet ports with 1 Gbps speed capability, making it an excellent choice for extended online sessions, including meetings, 4K video streaming, and online gaming. When connected to the G34, my device could achieve download speeds of up to 949 Mbps and upload speeds of 121 Mbps.

Security Features:

While the G34 excels in terms of speed and coverage, it falls behind in terms of security features. Although it offers fundamental features such as WPA3, VPN, and guest access, it lacks additional advanced security features. It is suitable for residential network setups but may not be the most practical choice for corporate environments.


The Arris G34 is the best modem-router combo for TDS currently available on the market. Its impressive speed and coverage, particularly in the near-band, make it an excellent choice for home automation. While it surpasses standalone modems in terms of available ports, it lacks features like link aggregation or multi-gig speed support.

Motorola MB7621

If you’re unable to subscribe to a TDS gigabit plan and are looking for a reliable option, the Motorola MB7621 is a solid investment. With features like DOCSIS 3.0, 24 x 8 channel bonding, and more, it is an ideal choice for pairing with the Extreme 600 plan.

Compared to its predecessor, the Motorola MB7420, the MB7621 offers noticeable performance improvements, thanks to the upgrades it incorporates.

One of the key advantages of the MB7621 is its maximum speed cap of 900 Mbps, making it a suitable match for the Extreme 600 plan. The DOCSIS 3.0 technology, combined with 24 x 8 channel bonding, ensures that the modem can achieve the promised throughput.

Additionally, the MB7621 is backward compatible with older DOCSIS versions, allowing you to pair it with lower-speed plans. However, this device may be overkill for such plans due to its resourcefulness.

In terms of performance, the MB7621 consistently delivered downloads at an average rate of 573 Mbps, with uploads reaching 97 Mbps. These speeds are more than sufficient for smooth online gaming, video conferences, 4K streaming, and other bandwidth-intensive activities.

In terms of ports and connectivity, the MB7621 follows a similar pattern to most modems on my list. It features a single Ethernet port capable of handling speeds up to 1 Gbps. This makes it well-suited for data-intensive tasks. During my test with Destiny 2, the modem did not exhibit lag or throttling, maintaining a ping value of around 21ms with a stable 60 frames per second.

If you’re looking to replace your rented TDS router and maximize the performance of your subscribed mid-tier plan, the Motorola MB7621 is an excellent investment. It offers reliable and efficient performance, particularly for those on a budget. However, its inferior features and performance compared to my top recommendations place it in the penultimate position on my list.
