The main difference would be the chip inside the modem. Unfortunately, the ARRIS has the flawed Puma 6 Chip which leaves users vulnerable to DoS attacks and has random latency spikes. While they have updated the firmware and claim it is better now, your going to have a safer bet with Netgear who uses the trustworthy Broadcom Chip.

Other than that, they are both approved for all cable internet providers. Yes, compatible with any cable ISP. However, the Netgear is 24 download channels while the Arris has 32 channels. The thing is, they both exceed expectations and minimum requirements for the top tier speed packages available so this does not really matter. In this case, their number of bonded download channels is not a deciding factor for any current situation you may encounter. Unless you want Gigabit speeds, then you need to get a standalone DOCSIS 3.1 modem and a strong enough router.

The Netgear Nighthawk Has AC1900 Stronger WiFi

The Netgear Nighthawk C7000 modem router has a stronger wifi rating at AC1900, while the Arris SURFboard SBG7580AC gateway cable modem is rated at AC1750. This is not a huge difference, so do not let it change your decision. Performance-wise, one could say they are almost the same with the Arris SURFboard and the Netgear Nighthawk having the same download capabilities but the Netgear having a slightly better wireless rating, making Netgear the winner here.

Is that enough though? No, it’s not. The main difference that stands out to us is the Netgear has the well known Netgear Nighthawk interface and firmware that has been preferred by most tech support gurus for decades. Meanwhile, the ARRIS SURFboard has the lesser-known, the lesser-used and lesser preferred interface and firmware built on top of the flawed Pump 6 chip. I myself used it a bit because my ex-girlfriend went against my recommendation and bought it to save money. I did not like the interface. It felt dumbed down yet complicated and non-intuitive, even for me. She only bought it because it was cheaper and she did end up having to replace the ARRIS because her house was too large for the AC1750 wireless router.

The biggest difference though? The Arris combo modem does not have a USB port. Yes, you may see one on it, but it does not have functionality. It is likely for a service port if you have to return it and they need to upgrade the firmware or something. The Netgear C7000 combo does have a USB 2.0 port. Why does this even matter? The USB port allows you to plug in an external hard drive and create a network-attached storage so that you may back up your files from any computer in the house and even put your downloaded movies onto it for your smart devices to access them and stream. It’s really ideal for anyone not living in a cave. And of course, this means you can hook your printer up to the router and put it in whatever room your modem and router is in. This saves you space at your office desk.

For most people the combo modem will be the best option. A combo modem is both the modem and router in one piece of equipment. Because the devices are consolidated, you have a lot fewer wires and complications to deal with. It is wireless AC1900 so it is great for a 2-3 bedroom apartment to a normal 2 story house.

Cons: The reasons I would not go with this combo modem router is because I prefer two devices. Sure the router-modem all in one is a single device with fewer wires to manage, but I prefer two separate devices so if one fails, you only have to replace one. Bottom line? Great coverage, still good for non-power users who just want the easiest option for a normal-sized living situation. This makes it the best combo modem for cable subscribers with services from ISP’s such as Time Warner, COX, Spectrum, TWC, etc.

Do I need a combo modem or router?
Yes, you will need a router or a combo modem to get a wireless signal. Here are the differences.
Modem: The stand-alone piece of equipment known as a modem is the required device that picks up the cable internet signal coming into your home where the coax cable is. If you have only one computer and do not need wireless internet, you can hook straight into the modem without a router.
Router: The device that hooks up to the modem and cast a wireless signal and allows more than one computer/device to connect. It also has a built-in firewall to protect your network from intrusions.
Combo Modem / Router Gateway: Both of those in one piece of equipment to save space and simplify things. This really is the best cable modem option for most people in the market and why we recommend it to you.

Netgear vs. ARRIS – The Bottom Line

If you want the best combo cable modem router, then Netgear C7000 Nighthawk AC1900 reigns supreme. Not by performance rating, as it is almost identical to the ARRIS SURFboard SBG7580AC. It holds the title based on the built-in chip/firmware/software and the functional USB Ports. The ARRIS should be avoided in this situation.
