What Happens to Your Internet If Your ISP Goes Bankrupt: Brightspeed, Optimum and Cable One
Brightspeed, Optimum and Cable One have each disclosed a risk of bankruptcy in October and November 2026; here is what a Chapter 11 filing does to ...
The NETGEAR Nighthawk C7000 is a cable modem and WiFi router in one box. It replaces the gateway your cable company rents you, plugs straight into the coax outlet, and covers a mid-size home with dual-band AC1900 WiFi. Every unit we sell is tested by hand in the US and ships with a 90-day warranty and 30-day returns.
The C7000 is a DOCSIS 3.0 modem, and several large cable companies have moved their approved lists to DOCSIS 3.1. Whether this is the right buy depends on who you pay for internet.
| Provider | Status in 2026 | What to do |
|---|---|---|
| Cox | Status: NETGEAR certifies the C7000 for Cox plans up to 500 Mbps | Next: Confirm the model on Cox's certified modem list for your plan, then see our Cox approved modem guide |
| Optimum, Mediacom, Sparklight, Breezeline, and regional cable | Status: Many still activate 24x8 DOCSIS 3.0 modems | Next: Call or check your provider's modem list before ordering |
| Xfinity | Status: Removed from Xfinity's approved list in April 2026 | Next: Pick a DOCSIS 3.1 model from our Xfinity approved modems list |
| Spectrum | Status: Spectrum ends DOCSIS 3.0 support on October 28, 2026 | Next: Choose from the Spectrum approved modem list instead |
The C7000 works with cable internet only. It does not work with DSL, fiber, or satellite service, and it does not support home phone service bundled with your cable plan.

Connect the coax cable from the wall to the C7000, plug in the power adapter, and wait for the lights to settle. Join the WiFi network printed on the label, then open the Nighthawk app or a web browser and follow the prompts. Your cable company finishes the job by activating the modem on your account, which usually takes a few minutes online or over the phone. Have the MAC address from the label ready.
On Xfinity or Spectrum?
Both providers now require DOCSIS 3.1. Browse our tested DOCSIS 3.1 modems for models that activate today and keep working after the DOCSIS 3.0 cutoffs.
Both. It has a DOCSIS 3.0 cable modem and an AC1900 WiFi router built into one unit, so you do not need a separate router.
Xfinity removed the C7000 from its approved list in April 2026 along with its other DOCSIS 3.0 models. A unit already active may keep running for now, but it can fail to reactivate after a move or plan change. New Xfinity setups should use a DOCSIS 3.1 modem.
Spectrum ends support for DOCSIS 3.0 modems on October 28, 2026, so the C7000 is not a fit for Spectrum customers.
The modem's 24x8 channel bonding has a theoretical ceiling of 960 Mbps, but providers approve it for plans up to about 500 Mbps. It is a comfortable match for plans from 100 to 500 Mbps.
Yes. You can turn off the built-in router in the settings and connect your own router or mesh system to one of the Ethernet ports.
No. The C7000 has no phone ports and does not work with cable voice plans.
