Time Warner Cable’s major broadband speed upgrade is alive in the Astoria, Woodside and Long Island City neighborhoods of Queens, N.Y.

The Time Warner Cable Maxx upgrade is Time Warner Cable’s effort to catch up to other cable operators that have significantly upgraded broadband speeds for customers over the last 18 months. Time Warner Cable has traditionally been one of the slowest major cable broadband providers in the country, with most customers only able to buy speeds up to 50/5Mbps. But Time Warner Cable has also committed to keeping unlimited use service available to customers, unlike Comcast, Charter, Cox, Suddenlink, and Mediacom.

The free speed upgrades are the largest ever for Time Warner Cable, typically more than tripling speeds for most customers.

Stop the Cap! has heard from readers in Queens who discovered the upgrades took effect this week, so we have been able to take a closer look at what customers can expect as Time Warner rolls out upgrades across New York City and Los Angeles and finally extending faster speeds over the next two years in other cities.

The first notification your area is about to receive an upgrade will come in a letter from Time Warner Cable.

Customers subscribing to the fastest speed tiers may need new equipment. Time Warner Cable is using 8-channel bonding in Queens for its 100 and 200Mbps tiers and 16-channel bonding for its 300Mbps tier. Some older and low-end DOCSIS 3 modems only support four channel bonding. For instance, a customer using a four-channel capable Motorola 6121 modem in Queens with Time Warner’s 30/5Mbps Extreme tier will only get speeds up to 50/5Mbps after the upgrade. If the customer owned a Motorola 6141, which supports eight channel bonding, they will get the full advantage of the upgrade: 200/20Mbps. But even the 6141 isn’t enough for Time Warner’s top tier: 300/20Mbps. Customers would need an upgrade to a 16-channel capable modem.

Time Warner’s notification letter says customers can swap out a company-owned cable modem for a 16-channel capable model, currently the Arris TG1672g, either by mail, through an area Time Warner Cable store, or with a service call. The usual modem rental fees still apply.

The TG1672g (download user manual) is a fully capable broadband and Wi-Fi home gateway that also supports Time Warner’s phone service:

• 16×4 Channel Bonding
• Full Capture Bandwidth Tuner
• Multi Processor Technology with an Intel Atom Core Application Processor
• DOCSIS® 3.0 and PacketCable™ 2.0 compliant design
• 4 port Gigabit Ethernet Wireless Router
• 3×3 Integrated Dual Band Concurrent
• 2.4GHz and 5GHz 802.11n radios with Beam Forming
• USB 2.0 Host Port
• Upcoming support for DLNA and File Storage
• Two FXS lines of carrier-grade VoIP with HD voice support
• MoCA1.1 for in Home Video and Data distribution over Coax
• Dual Stack IPv4/IPv6 Home Router
• Internal Power Supply for Highest Reliability and reduced energy consumption
• Battery backup: Single battery pack for reaching a full 8 hours of standby support

If picking up new equipment, a Time Warner representative will probably let you know if your account is flagged “Maxx-capable,” which means your neighborhood’s upgrade is imminent or complete. Time Warner may also want to swap out your set-top boxes if you subscribe to cable television, although readers report cable television service and the on-screen guide in Queens doesn’t look any different at present. The backup battery inside the cable modem is rated for up to 10 years of life and is replaceable by the user for around $60.

Customers who own their own cable modem might have to buy a new one if they are seeking the company’s fastest speeds. Time Warner’s latest approved modem list should guide what, if any, new equipment you might need. If you are considering buying your own modem, you might plan your purchase around the model(s) that support the speeds you want.
