Arris Modem Gui

[Emerson Mata]

Seemslike the issue is that the modem may default into a 5GHz radio channel that is used by too many people in your area; therefore causing interference and making your 5GHz option disappear. If you run the scan per the instructions, and manually change it to a channel that is used least - it should make the 5GHz option appear.

I just replaced my Arris SB6190 cable modem with an Arris SB8200. My ISP is Spectrum. When I was using the SN6190, I could bring up the Arris Web Manager at 192.168.100.1. When upgraded my modem to the SB8200, I no longer could access this web address. My router is at 192.168.0.1. I can ping the 192.168.100.1 address. When I run Windows Network Diagnostics Troubleshooting, the response I get is "website (192.168.100.1) is online but isn't responding to connection attempts". If I connect SB8200 directly to my laptop without using the router, I can access the Web Manager.

@azcat71 Thanks for this information. I am good now. It would be nice if the Arris documentation provide the right IP address for the modem. The User Guide says I P is 192.168.100.1. I believed them as my SB6190's IP address was 192.168.100.1. I was in a live chat twice with Arris Tech Support and they were clueless. I can't thank you enough. I just moved my AX6000 to 192.168.1.1 as you suggested and all is well. I needed to keep on top of the Arris diagnostics as I was having issues with the cable drop in my house/. Spectrum fixed my issues which were in my attic at no charge to me. I just want to stay on top of it now.

Like you, I did not have the issue with my previous router. I did have to change the IP that was used in my devices for the new router but at the time it had not occurred to me that it would effect the modem sign on.

I contacted TP Link support and they were unable to help me when I had the issue. I got the answer on the Xfinity forum from one of their members. I guess that inspired me to help others in these forums.

Alright, yet another XFiniti issue post! Like many, I am having issues getting my mother's RBR20 to connect to the internet with the Xfinity Arris TG1682G Modem/Router.

I have enabled Bridge mode on the modem/router. When I go back in and check the wifi settings, they show disabled.

Next, I setup the Orbi and add the Arris modem/router MAC address. When I do that, Orbi shows the IP information from Comcast. When I remove it, it does not. However, in either state, it cannot connect to the internet and has a magenta light on it. It is cabled properly. I have searched through the Arris config to see if I could find any other methods to disable the wifi transmitters, but enabling bridge mode seems to be the only way.

Please make sure of the following

1. The Orbi "Internet/Yellow Port" is connected by ethernet cable to Arris TG1682G.

2. No other devices are connected to Arris TG1682G ethernet ports.

3. Arris TG1682G is in bridge Mode.

4. The Orbi is in router mode and setup to obtain WAN DHCP automatically.

5. Power off both devices. Power on Arris TG1682G first and wait until LEDs show active and Internet. The power on the Orbi.

Comcast/Xfinity like most ISPs only assigns an account 2 public IP addresses and only one can be assigned to a device connected to the ethernet ports. So if you have multiple devices connected to the Arris TG1682G they may be racing for that 1 public IP address.

Next, I setup the Orbi and add the Arris modem/router MAC address. When I do that, Orbi shows the IP information from Comcast. When I remove it, it does not. However, in either state, it cannot connect to the internet and has a magenta light on it. It is cabled properly.

Why are you setting up the Orbi and adding the Arris MAC address? Once you disable DHCP and setup the Arris in bridge mode, you should be able to use the app (still think it's the easiest and fastest way for an initial setup) and configure the Orbi router in router mode, and add satellites if needed. Once configured you can go to orbilogin.com and finish configuring the Orbi the way you want.

On one the various threads on this subject, I read someone suggested that. When I do not add it, I do not have an IP address from Comcast. When I do, I get an IP address pushed down to the Orbi (though I still cannot access the internet).

Go back and check your Arris settings. The modem needs to be active and the LAN portion technically disabled. Make sure, after changing settings on the Arris, and before connecting the Orbi, you reboot the Arris. This way the Arris will obtain the info from the ISP and assign an IP address to the Orbi router.

Trust me, I have. I spent 3 1/2 hours yesterday troubleshooting this. The only setting change I am aware of that needs to be made is enabling bridge mode. If there is another setting change to be made, no one has discovered and posted about it, as far as I can tell. I scoured every possible setting that can be changed in the Arris TG1682G and there is no way for a home user to, say, disable the wireless transmitters short of enabling bridge mode. If anyone has any suggestions on what else can be fiddled with in the modem, I'd love to hear them.

Check the Arris modems users manual for transparent, or NAT or Bridge mode features on the modems web page. I have set a few of these modems up for bridge mode and it's there. Been a while since I did my last one. Once it's bridged fully and you applied the change. Your RBR router should be connected to the 1st port on the modem. Power OFF The modem for 1 minute then back ON and let it sync. Then Power ON the RBR. I would factory reset the RBR and walk thru the setup wizard at 192.168.1.1 with a wired PC. This should help you get the RBR connected to the Modem.

I had previously asked and you responded. Did you remove all the other devices from Arris TG1682G except the Orbi and it's still not resolving a Public IP address.

"2. No other devices are connected to Arris TG1682G ethernet ports.

2. I do have things plugged in there so maybe that's the issue."

ISPs limit the number of Public IP addresses they assign to an account. Usually they only allow one device to resolve through the Ethernet ports. Most likely though when you put the Arris TG1682G in bridge mode the ethernet ports are not turned off. So if you have another device conneted the Orbi is racing the other device for that public IP address.

This is why most retail modems have only one ethernet port as the ISPs limit number of devices.

I would highly recommend only having the ORBI connected to the Arris TG1682G via ethernet and the other devices on the Orbi LAN ethernet ports

If it works at their house, look on the outside of your house for the NID/DMARC, run an extension cord for power and hook up at the NID. If it works there, then it is your internal wiring. If it still fails there (but works at neighbor) then it is on the comcast side of the DMARC and they are responsible.

Maybe check the cables? Other than that your best bet is a tech coming out. If the problem is on there end it is my understanding there is no charge. Or perhaps your modem went bad. I had that happen to me once, the power went out and came back on, and even though my modem was on a surge protector, the modem went bad. It powered up and all indications on the modem looked as if it was fine. A tech came out, replaced the modem, and was back up in minutes.

I have just gotten a new modem and set it up with Xfinity. I plug the Ethernet cable into the Google nest and follow setup in the Google home app, and it won't connect. The modems Ethernet port lights also don't turn on. What do I do to fix this. My new modem is an Arris S33.
