Nighthawk C7000v2 Extremely Slow Wi-Fi Compared to the Rental Unit It Was Supposed to Replace
So I ordered a C7000v2 a couple of days ago to replace my rental Xfinity Gateway and god I think that was a mistake. The Wi-Fi speeds out of this are abysmal and not at all what is advertised on the box (up to 800mbps on 2.4GHz, 1.9gbps on 5GHz). Before, my devices were able to get 600-700mbps down easily when not even in the same room as the Gateway unit. Now, I am lucky to crack 250mbps on 5GHz sitting inches away from the C7000v2 and 2.4GHz doesn't even touch 70mbps. Wired I still get my 600-700mbps, but the severe drop in Wi-Fi capabilities almost has me wanting to go back to paying a rental fee each month...
Am I missing something huge with this router/modem? How are they able to advertise this as being high speed? This should support well above what my current Xfinity plan provides (600mbps down), yet it has been a major disappointment. Anyone have any suggestions on how to get the full capabilities out of the C7000v2 before I just reach back out to NETGEAR for a refund?

What rental unit did you have?
Reason I ask is comcast has been renting out there XB7/XB8 units which are multigigabit Docsis 3.1 AX units.
The C7000 isn't even a docsis 3.1 device. Its an AC1900 docsis 3.0 device. A last generation AC router.
The speeds you're getting from it are about what you'll get with that combo unit.
Its not an apples to apples comparison as the equivalent combo device to compare the XB7/XB8 to is netgears CAX80.
That would get those speeds and is a same generation comparison.
also, link speed isn't the same as throughput speed and 2.4ghz is a slow network. You won't hit 800mbps over 2.4ghz or even get close. To read more about realistic expectations over wireless, this is a well written article. https://www.duckware.com/tech/wifi-in-the-us.html
In general, on a good day with good hardware in the real world you should see 125+ Mbps throughput on the 2.4 GHz band and 330+ Mbps on the 5 GHz band. Towards the end of 2022, the C7000v2 does not come close to qualifying as good hardware.
Recommend you get your money back. Think carefully about your replacement and reconsider the decision to get a combination modem/router unit. In the long term you will be happier with a stand alone modem and a stand alone router. You definitely want a DOCSIS 3.1 modem. Your choice of router depends on your needs and the capability of your client hardware. If you do not need the latest 6 and 6E Wi-Fi, there are some good deals on refurbished AC hardware on Amazon.
A good Ethernet cord is going to outperform Wi-Fi on a daily basis.
