unable to login GUI web portal to enable the guest Wi-Fi on SBG6950AC2

My Arris Surfboard router one day decided it didn’t like my password. I’d like to set up a guest account. Any way to get in or should I just buy a new router?

SBG 7400 AC2 Public Static IP setup

I recently purchased an SBG7400AC2 Modem for a Public Static IP. It was one of 4 modems approved by my Cable Provider when purchasing a static IP.I was given a gateway IP, Netmask, Device IP, and DNS servers.I was told by the cable company that I do not change the WAN settings and to leave it on DHCP. I thought this was odd because I thought the Static IP was on the WAN side, but anyway, When I try to set up a network using the provided public IP, I get an error message saying it was not a private IP address range, and I needed to use 172., 192., 10., etc… Am I receiving bad information from the Cable company or is there something else I need to do?My goal is to set my Unifi Dream Machine Pro to the Public IP address provided. I have tried pretty much everything I can think of. I even put the static info on the UDM-Pro and set the modem to bridge mode, but no luck. Thanks in advance!

How to return certified refurbished item purchased through Surfboard.com- SBG7400AC2

Hi!I recently bought an ARRIS SURFboard SBG7400AC2 Certified Refurbished (this was an accident, I meant to buy a new one!). Anyway, I need to return it because it doesn’t work. I’m trying to figure out how to return it, but all the customer support options say they cannot help me because my warranty is expired. (I bought it one week ago, January 6.)Surfboard.com says it should have a 1 year limited warranty, but I can’t find any information about that in the box. :(Thanks!

SBG6900 Modem, can't connect to network with either password or Security Key

I’ve had an SBG6900 cable modem for a few years. Just bought an 8200 and it didn’t work. When trying to connect my old modem back (SBG6900), neither my old password nor the ID key work to get in (it says, need additional information to authenticate). I can’t connect to the application manager because I am not on the network, and my laptop does not have an Ethernet port to connect directly. Does anyone have any thoughts on how to access the Arris portal without being connected to the wireless network?

SBG7600AC2 suddenly lost interest connection

I have had this modem for a few years. I've had no issues with it ever before. This morning, I suddenly lost internet connection. The modem restarted on its own, and when it came back on, it had no internet connection. The second light, the send/receive light, flashes at a very rapid pace, the internet connection light below it is off completely. It doesn't light up or flash at all. I've done a hard reset on the modem. I've done multiple troubleshooting sessions with Comcast today unplugging everything. At this point I have Comcast coming out tomorrow to look at things. I'm hoping to get some suggestions for what the problem could actually be. I feel like the issue is something with Comcast but I am worried they will just tell me to get a new modem. Thanks for your help!

Arris SBG6950AC2 - recent purchase for Xfinity .. now cant watch Amazon Prime videos/live TV

I recently purchased and installed an Arris SBG6950AC2 router/wi-fi cable modem for use on Xfinity/Comcast. Now I can’t watch Amazon Prime Live TV or Movies, etc. I get an error to contact Amazon customer support… I can watch YouTube and access FaceBook, etc. Can the issue be a setting in the Arris Surfboard SBG6950AC2 setup or permissions?Everything was working with my older TP-Link Model 7610. I get all the way to the “watch” page and then Amazon aborts the connection or does not connect.I verified my router is working ok to access the internet, send email, buy stuff from Amazon. Any input is greatly appreciated! Thanks, much, happy New Year! Charles

Lost original login information used to set up modem - SBG6950AC2

Hello, I am trying to set up the app on my mobile device using the pamphlet included in the box but it is not working. It was originally set up using another persons information rather than my own and they lost access to their email to get into the account. How do I, if possible , reset it and set it up to only my information and also get the app to work on my iPhone 11. I need to be able to have control of the modem and devices. Thank you.

SURFboard SBG7400AC2 2.4 ghz settings for security cameras which loses live stream after 2 seconds

Arlo camera connects fine to the SBG7400AC2 and functions fine except for the live streaming aspect, which only last two seconds and stops. I’m thinking there must be a setting for the 2.4 ghz connection that I haven’t set correctly or the live stream would remain connected.

No internet on Surfboard sbg6700-ac

A new Surfboard SBG6700-AC will not connect to the internet. Went through setup wizard and did a factory reset. All front panel lights are steady green except the INTERNET is green FLASHING. The computer communicates with the modem with 192.168.0.1. The computer shows “no internet”.What else can be done to get the modem to connect to the Internet?

intermittent internet connection on SBG7600AC2

Summary:The Client List of the web admin interface of the SBG7600AC2 is empty. There should be some reservations and number of devices attached.ISP: XfinityFirmware: 9.1.103AA85Had some intermittent connection issues the last few days. Xfinity had just done some network upgrade work in my neighborhood, so it may have been related to that. Got much worse with the gateway seeming to become unresponsive. Internal network routing failing and the admin pages not loading. Had to restart a number of times. I kept catching it display "Your unit is updating, please wait for a moment." with nothing happening and without any subsequent change in the firmware. Perhaps a bad update was also being pushed? That or my device somehow got in a bad state?A tech was out today and confirmed signal issues coming in as well as bad wiring in the house. That aspect should hopefully be resolved. Unclear if these are related.

Intermittent drops Xfinity using SBG6950AC2

Recently, I’ve noticed I lose connectivity to Xfinity for short periods of time. To try and narrow down the point of failure, I set up continuous IPv4 pings to google.com, the first hop in a tracert to the internet, and my local gateway (192.168.0.1).When the issue occurs, I first see dropped pings to google and the tracert first hop. After a few dropped packets, I see drops to my local gateway as well. The loss of packets to the local gateway surprised me but I’m speculating the Arris SBG6950AC2 modem may be reacquiring its IP config when the connectivity drops.The Xfinity bot doesn’t detect an issue on their end. Signal levels seem reasonable based on what they were when I first got the service. The Arris log shows RCS Partial Service, SYNC Timing Synchronization failure - Loss of Sync, and Lost MDD Timeout errors.I own the modem and was intending to update the firmware if necessary but discovered on this forum that the ISP is responsible for maintaining the firmware on the dev

Router/Modem only connects to some things sbg7600ac2

I have a SBG7600AC2 router/modem. It does not work with my gaming systems. It works for some apps on my phone but will cut on and off. Just overall spotty connections but I have gotten it to work for gaming once and speed was really good. Just stopped working though. I’ve been trying to change settings in the router with small success. Is this router modem outdated?

SBG7600AC2 Remote Management Issues

I’ve looked all over the web for a way to turn on remote management for my modem/router combo (model SBG7600AC2), but can’t find that option. Does this model device just not have it? Is it possible that the ISP is restricting me from doing this type of this? I just want the ability to access my modem/router remotely not having to connect to the local WiFi or Ethernet connections. I already have DDNS created and set up, but it still isn’t working.

Can't set up my SBG6950AC2 using the surfboard app

I’ve set up this gateway several times and the only problem I had was that all the old SSIDs keep popping up in my wifi settings. But now I’ve reset the gateway once again, and my computers, etc will hook up to it with the default settings. But when I try to set it up using the Surfboard app, I get to the point where I scan in the QR code on the gateway, and it is apparently reading it wrong. It gives me a message to “move closer to the mAX router.” I don’t have the mAX router, as noted above. I can’t get past this point, and if I try logging in through my browser, it’ll let me change the SSIDs, but when I change my admin/password info for security, I get locked out, and can’t get back into my admin site.What the hey is going on????I hope somebody can help me with this!

Low Upstream Power Levels on SBG7600AC2

The 4 Channel’s Upstream Power Levels on my ARRIS SBG7600AC2 are between 44.25 dBmV (the lowest) - 45.50 dBmV (the highest). Are those levels low? Can they be increased? If so, how can they be increased?I am experiencing low WiFi Signals for both my wireless Blink Camera System, and my Amazon Firesticks. If that signal is settable within my Modem\Router please help me increase it. If not, can ARRIS tweak those settings for me? Thank you!

How to access of the SBG7600AC2 modem in bridged mode with Unifi UDM-Pro connected

Well, I tried locating my User Manual for the SBG7600AC2 with no luck. I recall something about accessing the 7600 that is in bridged mode by accessing its 5G wifi. Also using 192.168.100.1 to gain access. Well that did not work. Is the only option left to disconnect it from the UDM-Pro and plug directly into the 1st port on the modem?Your thoughts
