(SB6190) - Cable Modem - DOCSIS 3.0 32x8 Gigabit Modem, [Check with your provider for compatibility]1 Gbps Port, 800 Mbps Max Speed, 2 Year Warranty - White

Easy to set up. had to call comcast to manually activate the device and after 30 minutes my internet was up and running. replaced my working SB6121 (4 channels) to this baby. Basically our speeds are the same. But now our bottle neck is not the modem, its our very old linksys router. So now my wife can stream to her phone and her computer and allow us boys to play PS4 and steam down stairs with no issues. Update: Added new router (Netgear AC5300 Nighthawk X8 Tri-Band WiFi Router (R8500-100NAS)). Now my speeds are pushing 100Mb. But these speeds are dependent on your internet service. But since the upgrades my frustration is not our set up but Comcast lake of care for customers. 15 MONTH UPDATE 12/23/17: Ok i am updateing this guy.. at the time i bought this it was expensive 130.00 now its 97. up untime a few days ago i was always locking around 28 channels and now im at 32 channels due to comcast increasing my bandwith from 70mbps to 100mbps. but actually my real downloads have decreased from high 80s to mid 70s.So thats a provider issue not my issues. WHat i like about this guy .. it has helped me trouble shoot my local connection.. in the staus tab you can see you power and signal numbers. at install my upload power numbers were in the low 50s.. and lots of errors.. then a few months in i notced my cable line on the pole was moved to a different branch and my powers were spiking in the 57 which droped my uploads.. which with no upload you basicly have no internet,. its like you can recieve a call but cant talk and you cant call out. ok so i called comcast they came out and yes confirmed i had TONS of noise on my line.. so much so that the MAINTENCE crew moved me to a different line so i wouldnt jam the entire branch. so we put a ne cable from the pole to the cable modem and POW now 40 power and stable.. it turned out that i have 2 smart metters right next ro the cable into the house.. the EMF which i now own a emf meter was UNGODLY. and leaking into the connection at the exter wall. since fixed no issues from my home to the pole. SO i like owning my own modem for this one aspect. I proved to comcast many times its not me its them. and it proved once it was me and not them. Since that fix i have little to no errors in error log and i can monitor noise and trouble shoot issues. IS it worth the price now.. YES and i might buy a second one as back up. Now that comcast is locking at 32 channels i might even expand to next up. but not yet. SO this is a GOOD buy . specially if you can trouble shoot your connection your self. It has helped with my connection and I am hoping i will not have to update for a few years. i did see this at costco for like 80.00 just last week but it was on sale.

I just upgraded from the Motorola SB6141 to the new modem which still works but wanted to be future proof for a few years. DOCSIS 3.1 modems are due to be released this year but at this point not even sure if Comcast can support it in my area. Also said to be much more expensive than the 3.0 versions. Figured for $149 can't go wrong with it. Now I've read through the comments of some issues with Comcast of not getting an IP after the modem is hooked up. For me I was able to successfully activate this modem online without issues. It took awhile for the modem to get the configuration file and firmware updates from Comcast. Then I opened up Firefox to be greeted with Comcast activation page. Then the modem rebooted which is expected to get the final configuration file. After that everything worked perfectly. Same speeds as SB6141 but wanted updated hardware and much better WebGUI. There are a a few things I have noticed with this new modem. I will list those in PROS and CONS: PRO: Same size as the old modem. Can't complain They moved the activity light to the back directly onto the network port. Love it. Had to use electrical tape on the old modem because the bright flashing light is too distracting. Much improved WebGUI that it no longer looks like website from the 1990s. Not that it really matters once the modem works you rarely ever see it. CONS: The boot up process takes alot longer than the old modem. I suspect is due to number of channels it has to go through and start bonding them. Once it's up and running it should stay up without issues. It will run hot. Right now it's winter in Northern California so it's pretty cold in my house. Before I disconnected the old modem the heat feels the same as the new one. So it will get hot during the summer same as my old unit. I don't think it's going to be an issue but beware to give it plenty of space around the modem to breathe. Not a fan of white case but it works. This is my forth Motorola modem over the years. Had SB4100 all the way up to this new one and none of them gave me a problem. Even though Arris now owns Motorola with Arris label it is still a Motorola to me which is a good thing. I do need to mention for those with IP problems during the initial setup is the the router connected to the modem needs to be set to DHCP on the WAN so Comcast can send special DNS server IPs for the activation. Once that is done and modem reboots it'll revert back to 75.75.75.75 DNS address. From there you can use Google DNS 8.8.8.8, OpenDNS or even Comcast's. If you can't change the router DNS to use DHCP WAN then best just plug your computer directly into the modem until it's fully activated and updated. Then from then on you can use it normally. Hope this helps to save you some grief.

I replaced the SB6141, which was suddenly cycling on and off and no longer stable (it turns out Comcast no longer supports the SB6141). I also updated my internet service to 100 Mbps, so it made sense to upgrade. So far so good, though it's only been hours. It's BLAZING fast! Absolutely no problems whatsoever. I'm streaming 4K videos on three devices, streaming audio on another, and accessing internet with other devices. I also have several home kit devices, so a reasonably heavy load. I'm posting early in the life of this modem because I did a little digging and recently found that there are problems with the SB6190 chipset that results in latency issues. Just search here for 1-star reviews. Because of this I'm testing this to the degree possible. I'm not a gamer, so maybe this won't become an issue? But I docked the SB6190 one star because the modem has not been recalled. I'll post more next week...

nice product work with my provider
