Xfinity Arris TG1682G Review

Xfinity, formerly known as Comcast Cable, is one of the leading wireless service providers in the United States. Being one of the largest in the telecommunications industry in the country, it is no surprise that the company has also ventured into the hardware industry, partnering with brands like Arris supply hardware for their wireless business.

We’ve reviewed a couple of Arris cable modem router combos on this website, with the more recent one, the Arris Surfboard SBG8300, impressing us with its utilization of DOCSIS 3.1.

Today, we are reviewing yet another wireless gateway modem made for Xfinity, the Xfinity Arris TG1682G. Will it leave up to the standards of the previous Arris product we reviewed? Let’s find out.

Arris has been really great (at least in our previous reviews) in providing Xfinity users with cable modem and router that will work for the network. Looking into the specifications on paper, looks like the Arris model TG1682G will not disappoint Xfinity users.

In this part of the article, we will take a look at all the features the Arris TG1682G can provide to future and existing Xfinity subscribers.

1. DOCSIS 3.0

The Arris TG1682G is built on DOCSIS 3.0 technology. This standard makes sure that the Arris TG1682G will be able to cover up to 1800 sq. ft., and can connect up to 30 devices all at once. This is also the first version of DOCSIS technology that features channel bonding technology (more of this below). This is also the first DOCSIS version that supports Internet Protocol version 6 (IPv6).

The DOCSIS 3.0 also ensures that the ARRIS TG1682G can reach up to 640 Mbps of speed. The throughput is 256-QAM (42.88Mbps per 6 MHz channel). This makes it a good choice for future subscribers which demands or plan isn’t above that speed. However, if your Xfinity subscription plan can reach more than the supported upstream and downstream speed of the Arris TG1682G, then choose one of the Xfinity supported routers from below.

2. 24×8 Channel Bonding Technology

As mentioned above, the Arris TG1682G features a DOCSIS 3.0 technology. The DOCSIS 3.0 is the first version to feature a channel bonding technology. In the case of the Arris TG1682G, it features a 24×8 channel bonding. This basically means it can handle multiple channels at the same time, versus the 1×1 of the previous DOCSIS 2.0.

The Arris TG1682G can provide up to 24 downstream, and 8 upstream channels. What it does is combine all the available speed on these channels to create a stable connection even after your Internet service provider limits your Internet speed during the peak hours. That is 24 channels of the same speed for the downstream, and up to 8 for upstream channel.

3. Dual band Wi-Fi: 2.4GHz and 5GHz

The Arris TG1682G features a 3×3 integrated dual-band concurrent 2.4GHz 802.11n, and 5GHz 802.11ac high power radios. That means, if you have newer device that supports 5GHz, you can take advantage of the amazing speed from the device. Also, if you happen to own a device which uses the more common 2.4GHz frequency band, the Arris TG1682G will also be able to provide that. If you don’t know the difference between the two, then we will try to explain it in the simplest way.

The 2.4GHz frequency is the most common of the three right now (yes, we now have 6GHz frequency for Wi-Fi but we won’t discuss it here right now). The 2.4 GHz Wi-Fi can have wider coverage but is also the slowest of all the three frequencies. It is also the most crowded since most appliances and electronics, like a microwave oven, Bluetooth devices, and baby monitor uses the 2.4GHz frequency. This makes the 2.4GHz more prone to signal interference.

The 5GHz, on the other hand, is relatively faster but can have a limited area of coverage. It is also less crowded because there is not much of anything that uses this frequency, making it the best bet for less signal interference. If you have a device that supports 5GHz Wi-Fi and is an Xfinity subscriber, you can take advantage of this frequency on the Arris TG1682G.

4. Multi-processing with a 1.2GHz Intel Atom chipset

The Arris TG1682G runs on 1.2GHz Intel Atom Core application processor, with multi-processor technology. That means, there are more than two central processing units inside the Arris TG1682G. This ensures that the Arris TG1682G will handle tasks smoother, with video streaming and online gaming working fluidly.

5. More ports

The Arris TG1682G offers many ports that can be helpful if you want to connect many devices all at once using wires. While Wi-Fi is available, Ethernet connection is still by far reliable and faster than wireless connection because it reduces some factors that can interfere with wireless data transfer.

The Arris TG1682G provides four Ethernet Gigabit ports, one USB 2.0 port, and two lines telephony. You can use the four Gigabit Ethernet ports to connect your devices, such as smart TV, game consoles, streaming player, and computer directly to your router for a more reliable connection. The Arris TG1682G also offers two USB 2.0 ports so you can connect USB devices like USB hard drive, and USB printer to make it centralized. Most especially helpful if you have kids at home that uses a single printer to print their outputs, or in an office space where there is only a single printer and USB hard drive that everyone can have access to.

You can also use the two lines telephony to connect 2 telephone lines for carrier-grade VoIP and HD voice support, or the Multimedia over Coax Alliance (MoCA) which also allows networking over a coaxial cable. The Arris TG1682G supports MoCA 2.0, which basically means, the coax can offer actual throughputs (MAC rate) up to 1Gbps. It also allows for low power modes of sleep and standby and is backward interoperable with the older MoCA 1.1.

6. Battery backup

The Xfinity Arris TG1682G also offers an option for battery backup unlike other routers around. This should allow you to use the connection even after power shutdown.


The Arris TG1682G paints a good picture in our review. However, it is really hard to recommend to people that are already using DOCSIS 3.0 combo as there isn’t any standout feature that can convince replacement. Also if you’re a user already of DOCSIS 3.1 device, forget about this as it won’t give you a speed bump you need.

If you are a new Xfinity customer though, which doesn’t need to like subscribe to a data plan that can reach above the supported speed of the Arris TG1682G, then this is a good choice. You got up to 640Mbps speed, and DOCSIS 3.0 technology which can cover up to 1800 sq. ft., and can connect up to 30 devices at the same time. It also has four Gigabit Ethernet port that you can use to connect your appliances and gadgets like smart TV, and game console directly to the router using LAN cable.

You can also take advantage of the one USB 2.0 port on the back of the Arris TG1682G to connect other peripherals like hard drive and printer to make it centralize. The device also provides two telephony lines for carrier-grade VoIP and HD voice support, and a single MoCA 2.0 for connection using coaxial cable.

Finally, the Arris TG1682G gives an option for a battery backup for a sudden power interruption. Overall, I think it is a good buy for users that is yet to use DOCSIS 3.0, or DOCSIS 3.1 device.

  1. You seem to be confused on the number of USB ports on this modem. In two places, you say that it has one. In another place, you say that it has two. There are two on my box. I came here to find out it they’re usable or are assigned only for technical support or upgrades.

    Your waffling on this issue makes me hesitant to take your review seriously.

    1. USB 2.0 is the generation of the USB and not the number of ports. The router has only one USB port.
