Wi-Fi Modems

I use this motem/router with Cox Cable’s 1GB gigablast plan.  Every day my WiFi has been intermittently cutting out where I’ve had to unplug to reset the motem over and over again.  I’ve contacted the ISP, and they aren’t seeing any outages regarding signal drops, and are saying this must be a router issue.  How can I get this issue resolved?  Additionally, when it is working, my devices in the very next room are getting pretty lackluster MBPS download speeds.  In the middle of the night, the signal drops turn off my WiFi baby monitor which is a little unsettling.  Please let me know what I can do, as the ISP is saying this is undoubtedly a router issue.

Hello, I have an issue with my router that has been going on for about 1 week . We constantly lose our wifi and the router then will blink green . This happens about 6-10 times a day. My question is … Is there an update that needs to happen or is this non router related ? 

Some reason when i enter my model SN it indicates “The Serial Number and Model Number that you entered do not match”

I am not able to sign into my routers GUI (192.168.0.1) . I login with the correct credentials and it gives me an error of "you must sign in first". Then when I try to log back in, it says someone is already logged in. Please assist! Thank you,W. Bower

How do I change the password for the GUI interface or the  192.168.0.1/login.php site?

I recently got the G34 and it works well.  I need to move it from one side of the room to the other, and I wondered: do you need to ‘aim’ it.  Like does it have better wi-fi coverage emitting from the front (or sides), or is it omnidirectional?I was saying to my wife: if you are shopping for microphones, you can see the polar pattern of the directionality of a cardioid mic.  Is there any directionality to the wi-fi distribution of the G34?Thanks!

How do I delete old wifi networks from my router?

internet speeds are slow, under 100mbps, when i was using the spectrum modem and router, averaged over 300…what might I be doing wrong? 

My ISP, Xfinity, has me on a 600mbps download 35mbps upload plan. When using WiFi on the 5G channel sitting 4 feet from the router with no physical barriers between the router and computer, the highest download speed achieved using the Xfinity speed test is 270mbps download. I am not expecting 600 but I would have expected something better than half the plan speed. What is reasonable? Is there anything I can do with the router to make improvements to the download speed?

Every time I try to log into the wireless gateway with my correct log in it says wrong username and password. To check the central app via menu- WebGUI selection. Which the sign is all right. Once I go to the GUI it tells me there was too many wrong attempts and it’s locked. What can I do? 

I changed internet providers and had to switch to their modem. I want to turn my g36 into a network bridge  because I have like 60 wifi smart bulbs/devices that I desperately don't want to have to reconnect. It was a nightmare the first time. Well unfortunately I can't login to the app because it doesn't have internet, and the web access says the password I have saved is wrong. How do I login without resetting? The whole point is so I don't have to reconnect all my devices. 

I don’t seem to be able to have any service on my network visible with this device. I’ve tried port forwarding ports 80 and 443 for my website (doesn’t work). I’ve tried using DMZ (doesn’t work). I’ve tried forwarding different ports and giving myself a static ip address (doesn’t work). I’ve seen the other forum post talking about setting all local addresses for the DHCP server, I haven’t touched that at all. Should I just get a refund and get a different device?

I have tried all the things I can find and nothing is working to connect my HP printer to my G34. Thoughts?

My G36 is 1,500 miles away. The cellphone that had the Surfboard app on it went swimming. I have a new phone. Is there a way to re-establish admin control without going to the G36’s location? 

Have had this modem since Oct 2025.  About a month ago, started getting frequent brief drops (~1 per hr).  Doesn’t last long typically.  Have checked with Xfinity a number of times when this happened and they show no issue with their line.  

I have an SBG8300 and it has been working well for almost 3 years now. This morning I canceled my TV service with Comcast and suddenly I had internet problems. Pretty strange, but I have no proof of anything.My problem is I can access some web sites, but cannot access many more. I know it isn't a web site problem because I can get to the same sites on my phone.For example, I can get to the arris web site, but not the support site (arris.my.salesforce-sites.com), from my PC. It is truly odd.Multiple reboots of the modem, by me and comcast, have not helped. They are sending out a tech tomorrow.At this point, I am trying to get into my modem to check things out, but it won't even answer a ping, much less connect a web browser to the IP address.Has anyone run into this before? If so, what did you do about it? Thanks,Chris

Give me a G36 latest firmware site that an  mso can request it from 

I have a Arris OBBD Router that I need to have the PW reset.

I have an Arris DOCSIS modem on ComcastSoftware Image Name:AR01.05.020.13_032624_735.NCS.20Model:G36The upload speed has been poor since I purchased the modem last year.  5-6 Mbps is typicalDownload speed is 700+ Mbps.   My previous rental modem from Comcast got around 300Mbps upload speed.   Comcast came out to check the connection & found no problems.   When the technician connected hist modem, he got about 320 Mbps upload. Do a need a replacement modem from Arris? 

Currently we use Arris DG860A modems in our network.I am testing an ARRIS SBG6950AC2 and it is not being able to connect to the internet.Our C9 see it and register it but no internet connection.It’s there a difference between these two?I thought this would be a plug and play thing.In checking the modem all settings look the same, but the WAN does not pick up anything. 

New G34 from Amazon, the only page I can connect to is the router page, but the modem shows no issues and I can ping just fine. (Edited private information)

I am unable to open some adult websites through my Arris G34 model modern but can access it through my mobile network. How to fix this security or parental setting issue?

I bought a G36 to run with Ethernet for home business reasons. Wi-Fi is activated, but I've still not understood how I can run the G36 using Ethernet only.I'm using Windows11 Pro.May I ask for help with this? I'm just going too fast.  Thank you 

I got a ARRIS G34 cable modem with WIFI.I had to remove the Surfboard app on my Samsung S25 ULTRA and reinstall it.having trouble connecting to it. I think it’s looking for the original log on info like G34-BF59-2 or G34-BF59-5G-2 and the numerical password. I have since changed the WIFI names and passwords.is it possible to change one back to the one of above settings and log back in with the app.or do i need to reset the entire modem…..why can’t they make it easy for people to connect the app to the modem.
