Cable modem, router for sale (both NetGear)

polrbehr

I'm putting these items up for consideration - NetGear AC3200 router
NetGear CM600 cable modem
Modem was purchased about a year ago, router about 3 years ago? I don't have the original boxes or paperwork but there is plenty of documentation out there. I do have the original power supplies for both. They have
both been reset to factory defaults and were updated with latest firmware about 2 months ago. They work exactly as they should, and easily covered my entire house with very good signals (approx 1600 sq ft); I used the 400Mbps plan from Optimum.
Only reason for selling is I upgraded to Optimum Fiber internet and have to use their equipment.

I would really like to sell them as a set, let's say Polkie price $120 shipped/insured CONUS? Any questions feel free to PM or email me here -> polrbehr at optonline.net

I could see requiring their modem to convert the light pulses into the electrical signal, but their router too.

The first thing I did was try to figure a way to ditch their gear, but it seems like I have to keep the modem/router combo (and the corresponding $10/month "rental" ), they don't offer separates.
I was told I could keep the router in the loop, but the one that's included covers my house pretty
well and they even gave me a mesh extender at no extra charge - I may use that to boost outdoor
WiFi signals, but for now I get consistent 300Mbps ^ & v with the standalone, so I figured someone
else could make use of my NetGear stuff.

FYI, I also ran Cat5e to almost every room in the house over the years, I try to keep anything that can
be directly connected via ethernet, connected in this manner. It makes for almost instant Netflix streaming...

Thanks for the input though, now that I know you know what you're talking about, you can expect PMs
from me LOL

One and only price drop to $100 shipped CONUS, this modem by itself cost almost that much a year ago.

@gp4jesus I have AT&T Internet (legacy U-Verse), and like @polrbehr they tell me I have to use their "gateway," which is a combo modem and router. Assuming I want to stay with AT&T, is there a better way?

Sorry @polrbehr , I don't mean to hijack your post. If I could buy them, I would. It's a great deal!

polrbehr

No sweat, I will always accept a free bump to the top LOL

And believe me, if I could keep them, I would; they worked very well together.

polrbehr

I said one and only price drop. I lied. Will let these go to a Polkie (you all know the criteria) for $50 plus actual shipping to CONUS.

I figured if someone who wanted @treitz3 deal (killer, BTW) but didn't make it onto Santa's nice list, I'll bump this back in case someone can use them. Sorry, no splitty deez, package deal. PM me with interest or questions, or post them here, it's fine with me.

If you wanted to use your own router, you would call support and ask this question: "Is there a way we can configure the [service] modem/router for bridge mode so that I can use my own router and internal network equipment?"

polrbehr

He might've been in the same storm but in a different boat as me, @msg. I was never told I couldn't use my own router, only that their combo was what had to be in place with fiber. FWIW, their equipment is not all bad, but it is very user unfriendly - can't even change the default WiFi password, which I still don't understand. But since I was paying the $10/month rental anyway, and couldn't use the modem, I figured I would sell both.

Which by the way, is done. This will be on it's way to @pitdogg2 tomorrow.

So when I switch to fiber, the reps really botched the terminology of what its involved.

Fiber doesn't use a modem. It uses an ONT. Optical network terminal. This converts optical to ethernet. After this it simply goes to a router of your choosing.

They kept calling the router the modem in my discussions which created vast confusion.

The aftermarket ONT market is not really there so I kept what they gave me and went with a linear power supply no problems.

Good luck with the sale

polrbehr

I would have been ok with that. The first thing I did was look to buy whatever they were renting me, but the ONT Optimum uses seems to be proprietary and all-in-one. If my wifi speed wasn't good, I would've tried the router I had before because it worked great. But the choices were limited; go with their fiber gear, or go back to RG6. Only plus is they give you one mesh extender included in the monthly charge, so I have no dead spots anywhere.

What's the model of the unit they give you

polrbehr

All I can see on the label besides MAC address, network name, etc. is - Fiber Gateway GR140DG

That's it, no mfr. info at all. They probably don't want people replacing them on their own.

Interesting.

Looks like it may be a product by a Portuguese company, Altice Labs.

With typical combo modem/router devices, the private side can be configured for bridge mode, or "pass through". Quick skim of that manual shows a bunch of different device types in the family. Could be that that ONT Gateway doesn't allow for this configuration. I can't quite tell from skimming.

There's a workaround for this sort of thing in cases where you're not just getting an "ethernet hand-off" like Trey is, but it's not optimal, and it sounds like your coverage and speed is acceptable now with their extender.

One work around would be to disable the ONT Gateway's Wi-Fi, and set your own router to AP mode (Access Point). Then, plug your router into one of the ONT Gateway's LAN ports. There are a couple of other things one may want to consider here, but it complicates this response.

There are a couple of issues with this. First, it's two pieces of gear for the private side, and can introduce a little lag. It can also be buggy, and go unresponsive, requiring resets and such.

The main issue with this for most people, presuming that the ISP even allows access, is that the user still doesn't necessarily maintain control over or know how to control the device security.

Another consideration is port forwarding configuration to make internal services accessible to external requests, if that's something a person needs. Again, admin access to the ISP's device would be required.

I can see how/why ISPs would use a combo device like this by default for most subscribers. It looks like they're designed to provide bundled services from a single point - internet, voice, and TV in some cases.

@msg, what you said is true, ALtice Labs owns Optimum so that makes sense now. But I am fine with the speeds I'm getting, also the coverage with the ONT all-in-one w/mesh extender. And it can provide internet/CATV/VOIP, in fact their new CATV boxes are designed to just work off WiFi though all mine are hard wired anyway (the kid doing the installation was really surprised by this). My only complaint is I hated paying $10 monthly "rentals", which is why I bought the modem and router I am now selling! So it's back to the rental thing. I don't even know if I would go through the trouble again of getting another router unless I could change settings; it took me quite awhile to change every single wireless device we have to work with the new router.

Sorry about that bro'.
