Installing and Activating Your ARRIS SURFboard DOCSIS 3.1 cable Modem

[@Mike98006]

I'm a Comcast customer who just upgraded from Arris SB6141 to SB8200. I connected the new modem to my wireless router, replacing the old one. To activate the modem, I just powered it on, opened a new page on my laptop connected to my WiFi network, and was instructed by Xfinity to use their phone app. The phone app guided me through the steps to activate the modem, which was entering the MAC address of the modem and cycling power to the modem. I was up and running in like 2 minutes!

[@bigulf4872]

I did the Xfinity app steps, is that all you had to do? I'm not seeing my SSID pop up even though the Wi-Fi symbol is on

[@Mike98006]

@@bigulf4872 A modem is not a WiFi router and therefore does not have SSID. If you don't see the SSID of your WiFi router, check your router. It's definitely not an issue with the modem.

[@bigulf4872]

@@Mike98006 it's a 2 in one modem router, SSID is printed in the side

[@Mike98006]

@@bigulf4872 sorry, wasn't the case for me. And I would think your SSID would show up even if you weren't connected to Comcast. Do you have both 5GHz and 2.4GHz bands enabled in your router/modem? Maybe one of them is disabled and your computer can't use the other one?

[@bigulf4872]

@@Mike98006 well I haven't connected it to a computer yet so maybe that's the issue, I'm gonna go try that

[@alexjoat]

Word of caution. Unless you pay Comcast a small monthly fee, you can only use one of the two Ethernet ports on the ARRIS SB8200 Cable modem.

[@Bigcdt80]

Oh that's why I can't get the second port to work I just bought one of these last night and I honestly thought it was broken

[@jst601]

Please update this video. I purchased a new SB8200 July 18, 2022 & it didn't come w/ethernet cable. The box contents description didn't mention one either. It's not comforting to think that this kind of change could be made without anyone at Arris being aware of this video stating otherwise.

[@billf9847]

What is the second Ethernet fir and can you connect a second device to it

[@w4baham]

Is the hook-up for the Arris modem only and/or with the Arris modem/router combo the same? Don w4ba

[@josephshtekler1093]

You did not explain the use of the two internet output how they work and the use for them do i need two ip addresses?

[@escapedcops08]

If you don't already know how an internet output works on a single modem... Wow. It's a single modem, the two outputs allow connections to a router and pc among other peripherals that require it. You don't need nor does it provide 2 ip addresses. It's common sense, if YOU didn't know it's no one else's responsibility but your own to educate yourself.

What if I'm on a macbook and all we have in our home are macbooks and we can't connect our laptops to the modem? What are we supposed to do then? We had the service provided set it up and our internet is worse than it was before. My lights all are flashing yellow, what does that mean?

[@eyesofdarkness19]

[@epmrecords3364]

Dragon's Spectre then you use a Wi-Fi router to connect to Wi-Fi.

I have that one with two lan connections but the second does not connect to the internet. Why is that?

[@thebeertank5597]

I'm having the same issue. Only one port works at a time. I have one line going to my computer and one to my router for wifi but only one can work at a time. What is the fix for this?

[@tmastodon8174]

ISP is only giving you 1 ip address per port. I'm in a fight with Comcast right now to have them turn on my 2nd port (giving me another Ip address)

[@wsdudelive6335]

[@withjoe1880]

Not sure if you've figured it out, I am about to install one of these. My theory: Most ISPs only offer asynchronous upload and download speeds. DOCSIS 3.0 supports up to 1 Gbps ⬇️ and 100 Mbps ⬆️. DOCSIS 3.1 supports up to 10 Gbps ⬇️ and 2 Gbps ⬆️. These are maximum values and it is likely speeds will be lower due to noise, interfere, etc. As said in the video: 🟩=DOCSIS 3.0 🟦=DOCSIS 3.1 Run a speed test on Google and check your upload and download numbers against the DOCSIS specs. It's likely the upload can use the lower standard since they aren't providing you with as much bandwidth.

[@d.j_cam]

pita to setup my Arris G34 modem, tried numerous times with mobile app and barcode scan, then tried manually entering information, no go. very annoying and unnecessary. had to call cable provider to get it going

[@stevehumphries4928]

Alert: Xfinity (Comcast) supposedly supports this modem ... which I bought due to Xfinity contacting me stating that I need a doc 3.1 upgrade ... and that my old modem is no longer supported ... etc. I have had nothing but problems (losing connection) due to the fact that Xfinity can't keep the Upstream Bonded Channels power levels in the 45 and 51 dBmv range. Arris support say's anything above it 51 is too high and all-channel must be as close to a zero in a differential. Meaning all channels must be the same. So it seems Xfinity in reality in my situation can't control this ... I have called them many times over this issue and they keep telling me to reboot the modem. Now doing the same thing over and over again accomplishes nothing and its been going on now for a week since I got the new SB8200 modem. So for Xfinity customers, I don't recommend this modem!!! And I'm really pissed off because they so-call support it ... Update: Well Xfinity could never keep the voltage accordingly tell I removed the splitter and then finally it stayed in the range necessary according to Arris specifications. But I had no TV which means they have to come out and run a separate line which they charge for ... etc. What a scam! The SB8200 ran hot, I was afraid it would catch on fire ... but Arris support ran their test and said nothing was wrong with it. At any rate, I eventually returned the SB8200 for Netgear CM1000 and thus far, I have no issues! Wierd ... years ago I stopped buying Netgear because they would not last and ran hot ... and bought Arris only. The CM1000 has been running 12 hours now and not even warm! Boy thing has changed!If I have any issues I will update ...

[@urieljauregui2927]

Hope you are well, Steve. My modem stays flashing on the Upstream icon and I continuously get the runaround from Xfinity. Your comment has inspired me to research further on this topic as I am inept when it comes to this type of technology and the verbiage. Cheers!

[@stevehumphries4928]

@@urieljauregui2927 Well ... I figured out what was wrong or I at least have a theory. Eventually, I started having the same problem with the Nexus modem (CM1000), and still use it today. I believe you need two cable lines if you also use Xfinity Cable TV service. The TV signal and internet together coming in on the same line is causing the noise and thus interferes with the internet. I solved it by disconnecting the Cable Box and no more problem ... I just use the Xfinity Stream app now for my TV ... etc. You can request a separate Cable line if you wish but they may charge you for that ... but if you have ARRIS SURFboard DOCSIS 3.1 and have this problem of noise and losing connection ... try removing the cable box (remove the splitter if they installed one) ... turn off the modem and router for a couple of mins and turn the modem back on first wait 20 -30 sec. then turn on the router.

[@Sisonpyh]

how do I use the 2nd Ethernet port? it doesn't connect

[@stevelutzke9600]

Based on what I saw on another posting you need a second IP address and need to contact your provider to get one. They did state that they may charge an additional fee for the second address.

I do not think routers has any NAT or DDNS features, i.e., no way to assigned IP address to your computer.

Arris employees should be appalled and embarrassed that these videos are still on KZbin. Who within Arris is responsible for this? Why don’t your documents and videos agree with the devices you sell. Isn’t there a product manager at Arris whose job it is to make sure these items agree? This goes for the iPhone apps that connect via Bluetooth because of course there is no Ethernet port on a Mac. If there is anyone out there who can get a G36 AX3000 Wi-Fi (for Xfinity) cable modem to talk with my iPhone or Mac, I am happy to send you a reward! To Arris -> shame, shame
