I recently went with an Arris SB8200 modem, this is on Comcast’s supported list and since it’s DOCSIS 3.1 you should be good for a while. SB8200

...that makes it sound like a cabling (your in-wall stuff or the neighborhood infrastructure) issue. Or a username/password kind of thing, but I didn't think XFinity did PPPoE?

Also you replied elsewhere that you had to use their router in order to do full Gigabit speeds. Is that Fiber or DOCSIS 3.1? This guy should do it for coax connections, support for it is listed here.

Download is a little slow tonight.

If anyone is interested, I use this modem and router.

A wireless router is a router, switch, and AP combined into one device. When you go with separate devices, you need all three of those separately. The recommended Ubiquiti router is the UniFi Security Gateway. You'll also need a switch, you don't need a PoE one as the APs come with a PoE injector. You could get this basic one or this PoE one for example. Ubiquiti also makes switches, they're great but a lot more expensive and not really necessary.

For the APs, there are two good choices. If you don't have any devices that support more than two 5GHz streams and you don't have a gigabit connection, get the Lite. It's cheap, so get two and spread them out. If you have any devices that support 3-4 5GHz streams and/or you have a gigabit connection, get the NanoHD. The LR isn't really worth it, the longer range isn't very useful indoors, and your range is mostly limited by the range of your devices anyway.

As for the modem, the SB6190 has a bad chipset. Get the SB6183 if your ISP doesn't support DOCSIS 3.1, or the SB8200 if it does.

Maybe that gateway doesn’t display the boot file on your end, I can’t remember and without one in front of me right now I can’t say for certain. This sounds like the wrong boot file though and that’s handled on the “backend” with what codes are on the account.

I’d suggest you contact support and have them tell you exactly what the boot file name is displayed to them. Have them ensure you’re coded for gigabit and not some other plan, when I switched service plans my coding was wrong and I was getting download speeds of 400Mbps while getting upload speeds of 40Mbps ... yeah, had to call to get that fixed.

For instance, my boot file is “d11_m_sb8200_gigabit_c01.cm”

That’s gigabit service on an Aris SB8200 cable modem, I don’t rent the equipment from Comcast because it costs $156 + tax every year to rent that gateway and that’s more than the price of the cable modem on Amazon right now ($150). Granted, you’ll need an additional wireless router to provide WiFi of course but with everything besides my cell phone being hard wired that’s accomplished with an AC wireless router I’ve got DD-WRT running on.

That modem is fine for your current plan. Overkill, technically, but that's mostly them just trying to keep you renting their equipment. The one you're renting supports up to 640mpbs, it's irrelevant. Not sure about the wifi range, but it certainly won't be as good as an after-market device, but it will be comparable to what you have now (if you're using the Comcast as your wifi access point). However, you should have a separate router/wifi anyways, IMO. It provides better protection and better performance.

If you don't plan on getting a higher internet package anytime soon (300mpbs+), than this will be fine as your modem. If you are going to get a higher plan sometime in the next few years, then you may want to consider the SB8200. It will handle the higher speeds, and is more modern than the 6700. It does not have WiFi or a router, though. Call Comcast and verify any modem you purchase is compatible with them before you buy, just to be sure. Here is a site that lists compatible modems.

If you want something quick and easy, the 6700 will get you by. If you are looking to upgrade, then consider the 8200 and a wifi/router combo.

TL;DR

1. Yes
   
   
2. Yes
   
   
3. Yes (for the 6700)
   
   
4. Yes, but so does the one you already have (see above)
   
   
5. Should be about the same

I would highly recommend never using the Panoramic equipment. It is just awful. Mostly because of the software internet providers put on them. I always recommend using a separate modem and router. I've always used Netgear and Arris and had little to no problems.

If you want to stay in the same ecosystem, here’s my recommendation for Ubiquity. You may need more than 1 AP depending on the layout of the house, walls and placement.

You're not going to find any DOCIS 3.1 modem for under $100 right now. I'd wait and see if there are any good deals on this modem over the next couple months:

All are fine modems. I, myself, like the Motorola MB8600.

I don’t want to spend more then I need to. Should I get one or the other on the modem links below? The images shows a different speed then the header.

The second option states max speed is 686mbps but one of the images states only 250mbps or less? So which is it? Or should do I need the more expensive 3.1 gigabit modem?

Not if you’re going to Best Buy or Amazon. Most if not all should be fine.

For what it’s worth here’s the modem I have.

And the router if you need it.

Area doesn't matter whatsoever. Just buy something like this or literally just go on Amazon and type in "spectrum modem/router". There are tons. I used a nighthawk as my router and some random modem

I used spectrum until I moved last year. Had my own modem and router the whole time. If you want a good one they use, this one is good. Or just search spectrum modem/spectrum router on Amazon.

I have Cox, didn't want to be a moron using their subpar equipment for ridiculous prices so I bought my own modem.

Went with the Arris Surfboard and ended up going with Google Wi-Fi for ease of use as I'm not a hardcore tech guy and wanted a mesh network that was easy to use.

I actually bought the 3-pack for the Google WiFi and I love it. I actually had my own router prior to buying the Google Wifi and used that with the modem and got OK speeds, but switching gave me better speeds than what I was paying for. I pay for 100 down/10 (I think) up but I was getting sometimes 130 down/20 up.

I want to switch to gigabit internet but I'd need to upgrade the modem to the DOCSIS 3.1 version so I'm kind of mad I didn't just do that in the first place. Otherwise though, love the setup.

Always buy your own you can get better equipment that will last longer and you can pick your equipment. Get a two in one or you can get a separate modem and router and choose. you can get a cheap router that will get you by or get a super high end one that will last you years. average modem rentals 10 bucks a month so its 120 bucks a year. just for the rental.

​

This modem is 100 bucks and would be paid for in 10 months and probably last at least five years its a docsis 3.0 modem so it wont support full gigabit speed tho.

https://www.amazon.com/ARRIS-SURFboard-SB6190-DOCSIS-Cable/dp/B016PE1X5K

​

This modem is 165.00 and would be paid off in about a year and a half if you were renting instead and again will last at least five years if not longer and supports a gigabit connection so its somewhat future proof if your looking for gig speeds.

​

This is a decent two in one modem router combo for about 170 bucks it doesnt support gigabit speed but you wont have to shell out for a separate router.

​

The only time i would recommend renting is if you have absolutely no idea how any tech or wifi works and you just need it to work like magic. If your techie or like performance or know anything about modems or routers or you like getting under the hood and playing with settings get your own and save some money.

Source i work for one of the big bad ISP's lol

Residential. No Static IP. Would this one work?

Yay information! Yeah I was looking into this SQM, seems like it's not usually easy to find what something offers. If I read correctly though, a docsis 3.1 modem solves this?
So what about,

Only problem with this is I dont get a lot of LAN ports, any suggestion on a good switch that I could put behind a TV to split off to hardwire multiple devices if needed?

Surely these Mesh APs wouldn't provide full lan potential if not hardwired to the modem.

A thing to keep in mind is that you’ll get a $10 discount each month on your Xfinity bill. The modem will pay for itself (and then some) within 1-2 years.

>I can't buy a unifi setup due to low budget.

No, you do not need to buy a switch or a cloud key. All you need is the modem, a quality router, and a Unifi AP. Your router acts as a switch since it generally has 5 Ethernet ports, so the AP will just plug into the router. The cloud key is only for the Ubiquiti controller software. It's basically a dedicated mini-computer that runs the controller software for those who want to manage their devices remotely and get better statistical information. The cloud key is completely optional even though they say it's necessary. The controller software can be installed on your computer at home for the purpose of setup and that's it. Once you set it up, it's really powerful and extends your range quite drastically - I highly recommend. Just be sure to change the SSID and password to the same as your router, so that it handles wifi handoff on your devices.

This is the Unifi AP that I got. I would recommend at least a dual-band AC router with MIMO technology. There's plenty out there where you don't have to break bank, just pick a company that you want to support. I personally like Asus and I've heard great things about Netgear Nighthawk models. Either Asus A3200 or Netgear Nighthawk R6900P. Pair that with a good modem, such asMotorola Surfboard SB8200 (modem will depend completely on what your ISP supports, so don't buy that one unless you know). With this entire setup, you're looking at roughly $400. Even if you don't want to go the AP route, just going with a good router and modem to start will give you an idea of your wireless in your home/office. Unfortunately, working with a wireless signal isn't a one shot type of project. It requires several steps, but first start with the equipment that's feeding your internet.

You also didn't really explain anything in regards to your home/office setup: square footage, brick/drywall, metal obstacles, etc. All of these things play a factor in RF attenuation. You also didn't talk about your setup. Are we talking about being mobile with a phone and laptop, or is there a desktop involved? Are there streaming devices involved?

I haven't heard good things about either a range extender or a mesh system, but it works for some people. If you have a desktop computer, a USB network interface card would do you good.

I personally don't use cable internet anymore but Arris has been a great brand for me during my time on cable. Any problems I did have wasn't by the modem but was from the ISP, as recommended by other users on this subreddit. SB8200 is a great choice.

https://smile.amazon.com/ARRIS-SURFboard-Approved-SB8200-Frustration/dp/B07DY16W2Z/

As far as that router, I've heard good things about it. Another good alternative is the RT-AC86U https://smile.amazon.com/dp/B0752FD3XJ/

When I was making a decision buying a router, I came down to AC86U and the X4S (R7800), ultimately I chose the AC86U because ASUS firmware is better since I can use Merlin with it which lets my router gets the most up to date security fixes / enhancements / etc.

You mentioned gigabit, are you planning to get gigabit with Xfinity? If you aren't then buying all this equipment is a bit overkill.

This would serve you well. Or you could get the Docsis 3.1 version for a little more. They have some available from the Amazon Warehouse deals for $127.

There are many factors to consider here. The rep is correct. Comcast has built their fastest speeds, 250 and above, on DOCSIS 3.1 backbone. So, the fact you are using a DOCSIS 3.0 modem/router combo 24/8 may affect your speeds. The DOCSIS 3.1 modems include a 32/8 DOCSIS 3.0 connection which supports high speeds as well. Just because the box claims to reach those speeds, doesn't mean the ISP will allow it.

The modem the representative is trying to lease to you is the XB6 which is a DOCSIS 3.1 modem/router combo. This will be the only way Comcast will attempt to spend more than a few seconds on troubleshooting your slow speeds. If you lease the modem, then Comcast can definitely say it is something on their system or wiring and will attempt to remedy the slow speeds.

I am on the Extreme Pro 400 and I use the Arris SB8200 and get between 415 Mbps and 430 Mbps, hardwired. Also, I am using a Ubiquiti ER-4 for my routing. I linked both items I use.
