  • Key Specs
    • Wi-Fi Range: 5500 square feet (The device will provide a Wi-Fi connection to this approximate area.)
    • Wi-Fi Mesh System: true (A single wireless network consisting of a main router (connected directly to a modem) that connects to a series of satellite modules or nodes placed around the home. Routers with this capability promote stronger, faster wireless signals as well as increase Wi-Fi coverage by reducing interference and eliminating dead zones.)
    • Number of Wi-Fi Satellites Included: 0 (Quantity of Wi-Fi satellite modules/nodes for a Wi-Fi Mesh System that come with the product.)
    • Number Of LAN Ports: 1 (Number of devices able to be connected to the Local Area Network (LAN). LAN ports allow wired connections to other networking devices (wireless access points, range extenders, etc.) in order to share the internet connection received through a WAN port.)
    • Wi-Fi Speed: 6.6 gigabits per second (The maximum rate at which data is transferred between a network device and wireless router.)
  • General
    • Product Name: SURFboard mAX AX6600 Tri-Band Wi-Fi 6 Mesh Router – Model W21
    • Brand: ARRIS
    • Model Number: W21
  • Security
    • Data Encryption: true
    • Encryption Type: WPA2 (The security protocols or certification programs that protect the Wi-Fi network.)
    • Firewall Type: Other (The method the firewall uses to filter and process data to increase network security, primarily by blocking malicious traffic requests while allowing legitimate traffic through.)
    • Security Features: Secure setup via SURFboard Central App
  • Network
    • Band Technology: Tri (Refers to the number of frequency bands used to wirelessly transmit an internet signal. For example, dual-band devices may use one 2.4 and one 5 GHz band, while tri-band devices may use one 2.4 and two 5 GHz bands. Multiple bands also provide more flexibility for designating connected devices to specific band use.)
    • Ethernet Standard: 10/100/1000 (Each standard is a variation of the IEEE 802.3 set of computer networking technologies known as Ethernet. New versions evolved to include higher bandwidth, different physical media, and other new and improved features. Standards are often denoted by speeds (in Megabits per second). For example, a 10/100/1000 Ethernet port transmits at 10 Mbps, 100 Mbps, and 1000 Mbps (1 Gbps).)
    • Number of Antennas: 8
    • Frequency Band: 2.4 GHz, 5.0 GHz (Bands may be grouped into categories such as low- and high-band VHF (Very High Frequency), low- and high-band UHF (Ultra High Frequency), or certain frequency channels (measured in MHz or GHz). Generally, higher frequencies transmit information faster but have shorter range than lower frequencies.)
    • Wireless Networking Standard: Wi-Fi 6 (The wireless networking standard used by the device. Each iteration of the standard developed by the Wi-Fi Alliance corresponds to an existing IEEE 802.11 protocol; for example, standard 802.11ac (or AC) is termed Wi-Fi 5. Refers specifically to the standard the device is designed to use, but ultimately determines product interoperability and backward compatibility including previous versions.)
    • Wireless Standard: AX (The wireless networking protocol used by the device. Each iteration of the protocol is based on the 802.11 standard developed by the Institute of Electrical and Electronics Engineers (IEEE) Standards Association. Denoted by letters following 802.11 (802.11a, 802.11ac, etc.), each version, published in alphabetical order, encompasses all previous versions.)
    • Wi-Fi Range: 5500 square feet (The device will provide a Wi-Fi connection to this approximate area.)
    • Number of 2.4Ghz Streams: 2 (A router's streams are like lanes on a highway. The more streams a router has, the less traffic congestion. Because the 2.4 GHz band is used to transmit wireless signals to a wide variety of devices, there is often high amounts of traffic on that stream. But with multiple streams, each can be designated to a specific device for optimal performance. For example, if one 2.4 GHz stream is assigned to one device, such as a desktop computer, it leaves the remaining streams open for guest users, devices that use more data, or devices with specific band compatibility.)
    • Number of 5.0Ghz Streams: 6 (A router's streams are like lanes on a highway. The more streams a router has, the less traffic congestion. The 5.0 GHz band provides high speed, short-range data transmission and typically has less traffic than the 2.4 GHz band. With multiple streams, each can be designated to a specific device for optimal performance. For example, if one 5.0 GHz stream is assigned to one device, such as a streaming media player, it leaves the remaining streams open for guest users, devices that need less data, or devices with specific band compatibility.)
    • Wi-Fi Mesh System: true (A single wireless network consisting of a main router (connected directly to a modem) that connects to a series of satellite modules or nodes placed around the home. Routers with this capability promote stronger, faster wireless signals as well as increase Wi-Fi coverage by reducing interference and eliminating dead zones.)
    • Number of Wi-Fi Satellites Included: 0 (Quantity of Wi-Fi satellite modules/nodes for a Wi-Fi Mesh System that come with the product.)
    • Number of Wi-Fi Satellites Supported: 2 (Maximum quantity of Wi-Fi satellite modules/nodes that are able to be connected to the main router in a Wi-Fi Mesh System.)
  • Certifications Listings & Approvals
    • ENERGY STAR Certified: false (Devices carrying the ENERGY STAR service mark, such as computer products and peripherals, kitchen appliances, and other products, generally use 20% to 30% less energy than required by federal standards.)

    • Wireless: true
  • Ports
    • Number Of WAN Ports: 1 (Number of devices able to be connected to the Wide Area Network (WAN). This type of port may simply be labeled "Internet," and it allows the device to share its internet connection with all devices connected to it via LAN ports.)

Whats Included
  • 1 - mAX router unit
  • 1 - Power adapter
  • 1 - Ethernet cable

Q: Will this work with spectrum?

A: Yes, you can use this device paired with your existing cable modem/ wifi cable modem with spectrums' service

Q: Is it possible to turn off the front light?

A: Nearly. You can control the brightness within the app down to as little as 10% of full intensity. I have one of mine set that low and it does not distract at all. I presume it cannot be fully disabled as the LED colors indicate if there is a problem (red is offline) and the status whenever it is rebooted.

Q: Will this work with AT&T since it has a land line port?

A: Hello, this model does not have a land line port. However, it will work with any internet service provider. You simply connect your AT&T modem to this router for Wi-Fi coverage.

Q: Can I use this with hugs net? To make my internet faster?

A: This router will work with any modem as long as it has an Ethernet port to connect to the router. Your internet speeds (download & upload) are dependent upon the speed plan you subscribe to and the ability of your modem. The Wi-Fi then takes that connection and shares it around your home. Without knowing what speed your existing Wi-Fi is, it's hard to say. The Wi-Fi speeds of this router are 6.6 Gbps.

Q: Will this router work with a Verizon FIOS TV only package?

A: This router requires a connection to an internet modem in order to work. There is no internet built-in.

Q: Would I be able to use this if I have a century link modem

A: Hello - yes, this router is compatible with any internet service provider. You simply connect it to your existing modem. If that modem has Wi-Fi built-in, you would need to disable the Wi-Fi so that this device becomes your Wi-Fi router.

Q: Will this work with the SURFboard SBG10? Or should we update completely?

A: Hello - the SBG10 has built-in Wi-Fi. However, if you wanted to expand your Wi-Fi Coverage you could disable the Wi-Fi in the SBG10 and use it just for the modem functionality and setup your SURFboard mAX Mesh Wi-Fi system for expanded and faster Wi-Fi.
