I really wouldn't worry much about a long warranty. There are no moving parts in these things. The simply don't break. I certainly wouldn't pay extra for a longer warranty. No, not even $9.

I've used my own modem and router on Comcast for years. I currently have an Arris 6190 modem and NetGear 4500 router. My previous Motorola modem lasted about 5 years.
DOCSIS 3.0 gains bandwidth by bonding together 6MHz channels, each of which can carry about 38Mbps. A 24-channel modem could deliver 912Mbps downstream, and 32 channels could boost that to [b]1.2Gbps
"Real world" effective throughput speeds are much lower than advertised maximum downloads, and is based on many factors:
total number of users
bottleneck speed
type of services accessed
cache and proxy server usage
MAC layer efficiency
noise and errors on the cable plant
many other factors
Typically an 8 channel modem is advertised at maximum download of 343 Mbps. My cable company will only let you use an 8 channel modem for speed tiers of 50 Mbps or lower. The cable company will not permit you to use the 8 channel modem for the 250 Mbps speed tier. It creates a problem for them.
A 24-channel modem is advertised at a maximum download of 912Mbps downstream, but my cable company will only let you use a 24 channel modem for their 250 Mbps speed tier. If you want the 500 Mbps or the 1000 Mbps tier, then you must purchase a 32 channel DOCSIS 3.1 modem.
But you are correct that DOCSIS 3.1 will allow speeds up to 10 Gbps, so it may permit future applications for holograms.
The best advice is only to purchase a 32 channel DOCSIS 3.1 modem that is powered by a Broadcom chipset. The Intel Puma chips have a serious defect in them and are likely to go offline repeatedly. They are the subject of a class action suit. But try not to purchase a modem with this Puma chipset. There is a big problem with Puma version #6, but it is also present in Puma version #7. It may take some hunting to figure out what chip set a modem uses.

The Puma 6 was used for hundreds of millions of modems and other pieces of equipment. Similar problems showed up in both the Puma 5 and Puma 7. Avoid buying these modems
The list on this class action lawsuit website is not complete.
Quote:
Intel has confirmed the defect, stating that the company is "aware of an issue with the Puma 6 system-on-chip software that impacts latency," but after numerous months, has failed to release any update that fixes the issue. Cable modems containing Intel's Puma 6 chipset that may be affected include:
According to The Register, "The problem appears to be that the x86 CPU in the modem is taking on too much work while processing network packets. Every couple of seconds or so, a high-priority maintenance task runs and it winds up momentarily hogging the processor, causing latency to increase by at least 200ms and, over time, about six per cent of packets to be dropped. It affects IPv4 and IPv6 – and it spoils internet gaming and other online real-time interaction that need fast response times." Even users who do simple web browsing may be affected by the momentary high spikes in latency, causing websites to feel sluggish or not load. https://www.classactionlawyers.com/puma6/
Net gear preferred.
Comcast/xfinity will piggyback off your paid service to create WiFi hot spots for its users. Be prepared to lock it down.
The router was the key to setting it up to deter 'xfinity public use'.
Comcast tried to tell me that I was not in compliance with their upgraded system. I bulked and got my associate to reconfigure . Net gear doc sis is fine.

I was wondering why I’d continually see those xfinity hotspots around. The fact that they cap service in many areas mean they shouldn’t be doing this - not to mention also potentially compromising the user’s network.
How much internet speed drop off is normal when you go from directly wired internet to wifi?
I had lost service for a couple days until some lines were repaired, and I was doing internet speed tests when the blessed internet came back. My computer got 117 download speed, the phone (standing right next to the router) got only 42, and out in the living room down to 12. My router is 5 years old and I own it. The tech suggested I should buy a new router every 3-5 years but didn't try to sell me one of their leased models.
