The surfboard modem series are known to be leaders when it comes to reliability. They used to be under the Motorola brand but now they are backed by the Arris brand. Back in the day, Motorola rolled out two types of wireless cable modem gateway.

The first Surfboard SBG900 DOCSIS 2.0 was based on legacy wireless G standard while the second SBG6580 DOCSIS 3.0 was based on wireless N standard. However Arris surfboard SBG6782ac DOCSIS 3.0 is based on wireless AC (802.11ac). So, no wonder you can say – it is an awesome cable modem router combo package.

It is the latest and fastest gateway technology in the market that combines a 4-port Gigabit Ethernet Router, 802.11AC Wi-Fi, and MoCA Networking.

What Makes Arris SURFboard SBG6782ac The Best?

Well, the SBG6782 provides super-fast Wi-Fi speeds of up to 1800Mbps with capabilities of downloading via eight channels while uploading via four channels at groundbreaking speeds of up to 343Mbps. The device allows running of the dual band simultaneously and features MoCa networking which supports Ethernet network over existing coax wiring. All these features make it run smoothly with little to no interference or lag.

What We Liked?

  •  Two in one cable modem and 802.11ac wireless router.
  •  Supports MoCA (Multimedia over Coaxial) allows extension of Wi-Fi over existing coaxial cable.
  •  Dual-band Allows running of two bands concurrently to facilitate all devices.

What We Didn’t?

  •  Lack of assistance and user manual.
  •  Non-user-friendly QoS settings.


Some Great Features and Benefits of ARRIS SURFboard SBG6782 Router

1. Modem & Wi-Fi Route:

The Surfboard SBG6782-AC Gateway by Arris serves as both a modem and a router. It supports both plug-in and use and wireless usability. For a more traditional feel and use, you can plug in a cable and use it as a modem. You can also use it wirelessly as a router without compromising on performance.

2. DOCSIS 3.0 cable mode:

Unlike DOCSIS 2.0, DOCSIS 3.0 is newer and being new means it has been improved on regarding speed and efficiency. Cable providers nowadays give preference to DOCSIS 3.0 infrastructure thanks to its optimal performance and superior throughput. In the SBG6782-AC, DOCSIS 3.0 allows ultra-fast download and upload speeds of up to 1800Mbps. It supports channel bonding with up to four upstream channels and eight download channels with speeds of up to 343Mbps, ideal for high-frequency streaming and uploading of high definition videos and large files.

3. High-Speed Data Rate:

The gateway device features the latest DOCSIS 3.0 technology which allows channel bonding. DOCSIS 3.0 enables up to four upload channels while maintaining up to eight downstream channels at 343Mbps making it perfect for cable subscribers. DOCSIS 3.0 infrastructure creates a platform that allows cable service providers to offer high capacity commercial services for businesses and high bandwidth services for residential settings.

4. Support Multiple SSID:

In addition to supporting many standard wireless securities, the SBG6782-AC Gateway supports multiple Service Set Identifiers (SSID). The SBG6782 allows the creation of multiple SSIDs per band. It facilitates network segmentation of up to eight SSIDs per single band.

5. Security:

Supports security protocols such as WPA/WPA2, WPS, WEP, TKIP, AES, 802.1x, and 802.11i. In addition to the protocols stated above, the SBG6782-AC features functions such as NAT, DoS, and SPI. The features mentioned help facilitate secured and encrypted file sharing over the network as well as scan incoming internet traffic to ensure no malware is allowed in the network.

Easy Setup and Usage:

Setting up comes in three very easy steps. First, connect the coaxial cable to the cable line then connect the Ethernet cable from the LAN ports on the gateway device to a computer’s Ethernet port. Lastly, insert the power cord.

Final Verdict

The Surfboard SBG6782 is worth a mention to cable subscribers. It is a two in one, a modem and a wireless router. The gateway’s sturdy hardware and relatively minimum throughput needs make it an attractive choice for cable service subscribers. Lastly, the mere fact that it is the first ever built cable modem on the market to support 11ac gives it a legendary status.
