The Arris Surfboard G36 is one of the popular modem router combos. This multi gigabit modem router comes with DOCSIS 3.1 technology and the built-in router is powered by WiFi 6 (AX3000). After 3 weeks of using the G36 with known internet providers like Xfinity, Cox, Spectrum, here’s my in-depth review.
Before I begin with the G36 review, this modem/router combo is easy to set up and supports most of the service providers in the US. Not only that, but since it’s a combo, you don’t have to purchase a separate wireless router. Besides, the in-built Wi-Fi 6 powered router makes the device stand out, secure, and seamless.
Everything said, For advanced networking enthusiasts, I always recommend getting a standalone modem + router setup over a modem and router combo. It’s because, the former offers better control, scalability, and is very flexible. However, for basic home or business owners, getting a modem/router like G36 should be suffice.

Arris G36 Review: Should You Pick it in 2023?
This isn’t your regular Modem-Router combo. Instead, Arris G36 is slightly behind Netgear CAX80 which is also a multi-gig setup. In the subsequent sections, I shall discuss some of the most impactful aspects of this device at length to help you take an informed call as per requirements and budget-specific comfort.
But that’s not why I would recommend you look into the Arris G36. After testing it for at least 3 weeks on gigabit plans from Xfinity, Cox, Spectrum, I feel that this multi-gigabit combo is good enough for 2023 and even the future.
1. Design & Build
The Surfboard G36 is a good-looking device, boasting rounded edges and a well-ventilated top layout. Despite weighing close to 3 pounds, which is quite heavy for a networking device, it manages to feel compact.
The dimensions at 11 x 10 x 1.1 inches are aesthetic enough and add to the vertical structure of this resource combo, made out of hardened, matte plastic.
2. Ports & Connectivity
If I were to elaborate on the design and form factor, it is the rear panel that comes with quite a few nifty little enhancements. At the fore are the 4 LAN or rather GigE ports, capable of letting your wired devices experience multi-gig speeds. The ports support link aggregation as well.
Not just that, you also get a 2.5G port for ensuring the best possible internet speeds without having to rely on link aggregation and multiple IPs. Plus, each Ethernet port has an LED attached to it, indicating the operational status.
As far as the routing setup is concerned, this is an AX3000 device, capable of supporting excellent 2.4GHz and 5GHz throughput. Plus, the Wi-Fi 6 standard ensures minimal connection drops and better battery backup.
3. Compatibility with ISPs
The Surfboard G36, unlike some of the other products from Arris, is compatible with almost every cable ISP. This includes Spectrum, Comcast, and obviously Cox, whose Gigablast plan was used to test the device.
Plus, regardless of the internet plan or ISP you tag along, the inventive UI and app-based support offered by the Surfboard G36 lets you have access to the remote device manager, parental controls, network manager, and even speed analyzer, making device usage a wholesome experience.
4. Hardware & Technology
At the core, the G36 has a multi-core processor, capable of handling congestion like a pro. The existing chipset ensures that you can make the best use of the DOCSIS 3.1 technology and the fallback to the DOCSIS 3.0 with 32 x 8 channels to work with. However, once ISPs start rolling out internet plans well above the 2Gbps mark, this device can be a handy asset.

Adding to the performance are the internal antennas, which are more than capable of keeping the connections steady. In addition to these specs, the Surfboard G36 also accounts for IPv6 support and AES encryption to keep online threats at bay.
5. Wi-Fi Speeds & Range
This modem-router combo allows you to reach theoretical wireless speeds of up to 3000 Mbps. However, when tested with the Gigablast plan, I could churn out 2.4GHz speeds of up to 220 Mbps and 5GHz speeds of almost 950Mbps. The range, however, is quite expansive as this device can cover almost 3000 sq ft of area, with varying degrees of network consistency.
The Pros and Cons
- Ultra-fast wireless connectivity
- Future-proof combo with DOCSIS 3.1 technology
- Comes with a 2.5G port
- Surfboard app speeds up device setup
- Perfect device for 4K gaming and streaming
- Pricey
- 2.4GHz speeds aren’t the best
Arris G34 vs G36
When you compare Arris G34 with the G36, the G36 comes across as a better device, courtesy of an exclusive multi-gig port, as mentioned, and the ability to support internet plans with a throughput reaching up to 1.2 Gbps.

Have a new G36. Can’t connect to my wireless printer. Something about NO FILTERING. Any idea what to do? thx Manny
Sorry, should add the printer is an HP 6520.
I read 2 reviews on best buy’s website that this combo will not work with the cisco any connect vpn or any vpn. I think this is an important downside if this is the case
It is working fine when I utilize NORD VPN. I cannot speak to any other VPN.
I previously replied that NORD VPN worked fine with the G36. Alas, it does not. I was connected via a different remote router when I was using NORD VPN. My apologies for the inaccurate statement.
I need to use NordVPN. Should I buy the Arris S33 and connect a router? Which router would you suggest? Thanks very much!
Linda
FWIW – I’m using Cisco AnyConnect and no issues thus far..
For the COX Gigabit Plan with fiber glass, if I already have Amazon eero Pro Mesh devices, do I still need the router part ?
I bought AARIS G36 from AMAZON about a month ago, and it failed to power up. Totally shocked of its failure. I don’t believe spending $320 and owning a lemon.
Hey Paul,
I’m sorry you had to go through this. Arris G36 is a powerful device and it shouldn’t go bad within a month.
It must be your unit-specific issue. Even now, my G36 is working just fine as on day one.
Thanks for your input.
Somehow, the unit I received broke down. IP company changed the supply line, did all trouble shooting inside/outside. Finally, They told to contact ARRIS to change the modem. The IP company offered me a one year loner free of cost, but I declined.
The new unit works very well. Happy to own it.
Thanks
I bought the G36 and I can’t get it working and I have xfinity. If you stand right by it you will get a connection if you walk away no connection. What can be causing this? Thanks
Hey Scott,
This is strange! It should not behave like this.
I’d suggest troubleshooting Xfinity internet and see if that helps.
If not, your unit might be faulty. Claim warranty and get it replaced/repaired.
Ok thanks for the advice….
Does the 2.5Gbps provide any benefit if you only have 300 Mbps internet service?
Hey John,
No, having a 2.5G modem for a 300 Mbps internet connection is overkill.
For a 300 Mbps plan, a DOCSIS 3.0 modem with a Gig ethernet port would do.
I hope this helps.
Purchased a G34 and worked fine for a minute. Later had to reset it every once in a while. Comcast told me I needed to upgrade. They’re website recommended several. So I went for the G36. Worked fine out the gate after ISP set it up. Two weeks late I was having to reset it everyother day.
Aways coming up “wifi w/no internet.
My security camera from Xfinity went bad too. Had to be replaced. Xfinity was going to send out a pod but told me it wouldn’t work with a customer own modem. Sent me a new camera instead. I felt Xfinity is playing games so I have to go back to renting they’re equipment. Going back and forth with them. So if you have any reasonable suggestions I’m open.
Hey Anthony,
I didn’t come across WiFi or No internet issues ever, with the ARRIS G36. It can be some issues from the service provider’s end.
Maybe they might want you to rent their equipment. Also, ensure your WiFi router is fine (and capable enough).
Kind of what I figured. Something to do with the up and down and have to locate a different IP address or some crap. A technician was out to install the 3rd one of Xfinity cameras and told me to disconnect the coaxial cable from the router when the camera cannot find the internet.
My Vizio TV can never find a signal with out powering down with a hard reset and back up. But the Ruko connected to it works fine. Installed and extender that helps somewhat. So I’ll keep working the problem.
