Wi-Fi Modems

I am locked out of my router modem.  Anyway I can help myself?

Thank you to the community members who have reported intermittent connectivity with their G34 and G36 devices on their Xfinity Internet service.  Recent Service Provider upgrades to their network for DOCSIS 3.1 higher upstream capabilities as well as preparation for DOCSIS 4.0 deployment have created possible issues with certain devices on certain upgraded networks – across all DOCSIS device manufacturers – that are impacting stability and performance.    We are committed to resolving this matter.  We are working with Xfinity on a long-term solution to update the firmware and will provide an update when this is completed as soon as possible.    In the meantime, the current workaround is to power cycle the G34 or G36 device to regain Internet connection.  We

Hello. My network says hidden and I can’t figure out how to unhide it. When I go to the Arris login and apply it has a checked box that says broadcast SSID and it is already selected yet still says it’s hidden. Is there something else I need to do? Thanks!

I have the latest 1.05 Firmware upgrade on my G36 router and the internet is constantly dropping 4 to 5 times a day.  The only thing that fixes the connection is a hard reboot of the router.  I can still see devices on the local network but internet connectivity is lost.Working from home makes this very FRUSTRATING!Any solutions in sight other than trashing this router?  

The 2.4 network is not working on my new AC2350 wifi 5 router/modem.Network occasionally appears but can’t connect to it. Frustrating because some of my devices can only connect on 2.4 and there is no reliable connection. Need to return it?

Hello, I have the following setup: Xfinity Internet of 1GB  Surfboard G34 Modem + Router Combo  4 Eero 6+’s I have the following 2 issues: When I enable bridge mode on my G34, my eeros no longer work and cannot connect to the internet. As soon as I disable the bridge mode everything works fine. I have been on 5+ hours of support with both xfinity and eero and still cannot resolve this problem  The above problem stemmed when I identified through a speed test that directly from my modem my internet speed is always ~950mbps, however when I run speed tests on my wifi with my eeros connected my speed is around 120-170mbps. This is a HUGE drop. I was trying to trouble shoot and hence backed into the above enabling the bridge mode which I cannot do and there are no other solutions.  Even when I check the speed from the 2 networks that are pushed through the G34 those speeds are even slower ranging from 100-

My sons Xbox shows up as one of the connected devices list in the app, but when I go into “My experiences” and I created a profile for him, then click his profile and “Add Device” the Xbox doesn’t show up as a device I can add to his profile- even though he is playing it right now - so it is actively online. Just not showing up. Every other device that is online shows up on the list I can choose from to add to his profile - just not the Xbox.Thank you,tara

What is the fix for these connectivity issues?  I had intermittent issues until the last couple weeks.  Today I cannot get it to work at all.  I know it is this g36 because I bridge connected my old tp-link modem router to the g36 and I can access internet thru the old modem through the g36 but not the g36.  We live in an area with little to no cell phone signal and rely heavily on our wifi and internet connection for wifi calling.  I also work at home and the internet connection is vital to my work.  This is extremely frustrating as this modem was not cheap and should work.  I have spent time trying to figure out what to do with this that has taken away time from my job.  I do not recall getting an email from arris or xfinity about any issues so I'm just finding out about this connectivity issue.  Extremely disappointed in this product.  

Installed Surfboard Central app on my android device, powered up BE18000 (G54), and activated the gateway via COX tech support.  G54 shows solid blue LED and provides ethernet connection. However, the QR Code rejected when requested during wi-fi setup via the app.  The reject message was something along the lines of QR Code not a readable format.  I’ve attempted a manual network setup on my android device but it didn’t work either.  The product label on the bottom of the unit shows SSID as G54-9DB1 but my android device only shows one G54-ABCD during network scans.  The default password on the G54’s label does not work with either G54-9DB1 (label SSID) or with G54-ABCD (network scan).  Suggestive solutions via similar threads have not remedied the QR Code scan reject.  As a result, I cannot complete the G54 wi-fi setup.UPDATE:  I’ve uninstalled and reinstalled the Surfboard Central app three times and still can’t connect to wi-fi with QR Code scan or setup manually options in

We currently cannot get internet in our bedroom upstairs and would like to get an internet extender.  Can anyone recommend an extender that is compatible with the Arris SBG7600AC2?  It seems Arris doesn’t have extenders so we need to know which ones are compatible with what we have.

my internet is going in and out for min or two at a time.why would this be happening? need some help asap

Also received the Xfinity firmware update version 01.05 for my G36 and still experiencing intermittent connectivity issues. Internet goes out multiple times a day every few days. Work from home. Reliable service is essential. Purchased the G36 as this was recommended by Xfinity. Constant rebooting is not a viable solution. Arris and Xfinity, please resolve this before you both lose another customer.

Hey All:Modem has been great for a few years. Like 10 days ago, internet just dies randomly, wifi networks are still up but can’t even connect to admin page. I see other people are having the same issue recently. What’s up? the only way to fix it is to power the modem/router down and up. I tried factory reset to see if that gets rid of potential malware. It was good for a few hours and died right as i was doing an internet speed test. Any advice. Should I try another modem? thanks

I’ve been having one issue after another with websites not loading even though the wifi is working and there’s no support around this and no one can resolve the issue. I keep having white screens and cleared the cache in the browser and now I can’t sign in to the web based manager because it says username/password is invalid yet doesn’t give an option to forget username/password. Someone please help resolve this because it’s causing me to lose both time and money!

Hello,I got hold of the CMTS Arris Cadant C3. Unfortunately the CF card is dead. Does anyone have a firmware image available, ideally 4.4.4.13?Thanks

For my xfinity service, I got my new G36 and began the signup process. I got to the part where I was supposed to contact xfinity, which I did. After a long time working on it, the tech got me set up. Meanwhile, I guess the Arris app had timed out. It seems to only give me the option of a re-install, like after a factory reset, But I don’t want to do that, because I don’t want to go through the painful activation process with Xfinity again. So what’s the best, most efficient thing I can do, to complete my setup? 

Why does my higher speed wifi keep dropping off.  I have to reboot every few days to get it back. Is there any wY to correct this issue?

I have a G34 and it is configured to provide both 2.4G and 5G networks. In the router, everything looks fine.  Broadcast network name is checked.However, the 5G network doesn’t show up as being available on any devices. How do I fix this?

The Wi-Fi Freen light is blinking. 

I’m locked out of SBG6950AC2.  I want to set a new password.  How can I do this?

I have the surfboard SBG6950AC2. The password I set will let most of my devices log in.  The thermostat will not accept the password.  When I typed in the modem url to log into the router it will not accept the password and is saying I’m locked out   I don’t know what to do now to log into the surfboard and change the password so I can use the surfboard for all my devices. 

Just switched to a Arris G36 and I previously had my network routed through some OpenDNS servers. At least I think, its been years .I set it up using the below primary and secondary. I know it was working before I switched, but after some initial test on the new modem/router it doesn’t seem to be blocking the sites it normally would. it also seems to kill my wifi. My direct connection works fine, when using the below.Primary      208.67….Secondary 208.67….Can anyone provide some guidance on how to set it up properly. Was putting into “connections/local ip/ IPv4”Thanks in advance.

I set up the router with the iOS app. I did not have to set a password. It sent me a verification email with a 6 digit code. I cannot log into the web based router because I don’t know the password. I tried the 6 digit code, but didn’t work.  The error tells me to use a valid email, which is what I’m doing.
