I recently found out that my normally cost-conscious father has been renting his modems from his ISP for like 25 years and for Christmas I want to give him the gift of not having to pay $15 a month to Comcast anymore, but I was hoping for some guidance.

He's currently paying for 800mb/s and they have him Arris TG3482G wireless gateway.

He lives in a ~1700 sf one story (plus basement) housee. All three bedrooms (and maybe the kitchen?) are wired with with ethernet jacks if that matters. Both he and my mom have said the signal in their bedroom can occasionally get spotty (in the rough sketch of their house below, the router is in the basement roughly on the X, room with occasional coverage issues is red square). That initially made me think maybe I should look into a mesh network, but then I realized it could just be that the signal on those modem/router combos really is that bad and a decent traditional modem could suffice.

Their internet usage typically consists of your run of the mill web surfing and occasional streaming. My dad also works from home over the wired connection.

They recently moved their landline over to Xfinity, so the modem requires voice. The modems xfinity lists as compatible with their plan:

  • NetgearCM2050V
  • Motorola MT8733
  • Arris T25
  • Netgear CM1150V
  • Arris SBV3202
  • Netgear C7100V
  • Motorola MT7711
  • Arris SVG2482AC
  • Arris SBV2402

Any thoughts on which modem and router would best fit their situation and needs? Obviously the CM2050V appears to be the superior modem on the list, but also seems like a overkill given their plan and usage habits (unless it'd be a good idea for a bit of future proofing in case their plan ever gets upgraded?).

That's 180 dollars a year though! And my dad loves saving money. He's pretty good with tech compared to other people his age, and I don't mind troubleshooting if it comes up. But I'll mention that to them in case they hadn't considered that aspect.

Just to make sure, I recommend calling their ISP provider to know exactly what you are giving up in terms of support, how much TS they can do to a cx owned modem, in which situations they will need to pay a technician appointment for an issue by having their own modem and the cost of the technician appointment

ISP agents know very well the leased modems but they may not know all the tricks on a owned modem, so always have their owned modem manual available, the manufacturers contact number, and most likely agents will not provide any assistance related to login to the modem settings and handle their wifi network, ports, etc, which your dad may be able to as you mentioned he understands technology.

But yes my advice as tech support agent of another ISP is to call them an know the policy they have regarding owned modem, and before going to their owned modem make sure everything on their network is working on point while having the leased equipment

I had Charter briefly and they refused to troubleshoot if I didn't rent their modem. If you call them for an issue with your service their base assumption was that the problem was your equipment. They would not perform any troubleshooting until you had replaced your modem with their modem. We never even got past installation because I told the installer to take it all and cancel my order and go home because the bill was way more than they had advertised. It was supposed to be $55 a month plus normal taxes and fees with a 6-month discount that would have made it like 25 bucks a month for a bit. But in addition to the $10 month modem rental there was also a $15 fee that made no sense. When I asked I was told it was a fee because I didn't get a bundle. Now they advertised their internet service by itself for $55 a month. You of course got discounts if you bundled in phone or television. But they also advertised each service on its own for a specific price. Apparently if you chose to buy that service from them or the price they advertised it as they charged you a $15 a month fee for buying the product at the price advertised without buying another product to go with it. I was already ticked off about the $10 a month modem rental fee but I wasn't going to pay an extra $15 a month on top of that for crummy basic cable internet.

Well yeah each service provider is only going to troubleshoot to the end of the equipment they are responsible for. For water that means your water meter, for for power your power meter, for ISP it means the outside line demarcation point where it turns into your equipment.

If they own the ONT modem/router they can troubleshoot to that point. If you provide your own all they can do is send a tech to make sure their signal is active and if it is they'll charge you. If you use their equipment they'll troubleshoot it and assume that the issue isn't a simple layer 1 issue, and if it is will.sometimes eat the cost on a quick repair if it means keeping you subscribed and happily paying equipment fees each month.

What I'm saying is they would not check the line. If you reported a service outage they would tell you it was probably your modem going bad since you weren't renting a modem from them. In order for them to check the signal and check the lines you would have to replace your modem with their modem. $120 a year for a piece of equipment that you can buy for 60 bucks it's just so ridiculous.

If they have no outages reported in the area and you're the only one down they will send a tech to test the fiber or copper line that feeds your home. If they find the line is good then the rest of it is on you and they'll likely charge for the techs time that did the test. They should provide a certified result of their fiber or copper line test though.

We have to deal with this all the time at our data centers. Even with in house techs that can test and tell us the fiber is down likely due to a line being cut by the construction crew 100ft away, the ISP will still send their tech to find the exact same results before they send out a repair crew.

As someone who has dealt with Comcast tech support a LOT, I would not believe anything they say about this.
