Wi-Fi Modems

For some reason none of the devices show up on my app so I am not able to pause/ remove unwanted devices. Please help

I have a G36 with Xfinity, purchased in 2023, been working fine. Two or three months ago, started noticing connection issues, everything would be disconnected from the WiFi network, I could restart it remotely through the app and it would start working again. The odd thing, is that it always says “your device is connected” in the Xfinity app, and their tech support says they see no issue.it’s been happening more often, and now when restarted, it often shuts the WiFi network down again after 5 minutes or so. Can’t always do it in the app, have to go upstairs to unplug it. Ethernet cable plugged into desktop, that network goes down the same time as the WiFi. Had Comcast reprovision it, and a tech came out to check, signal strength is showing no issues. Also have tried the factory reset button. Didn’t help. the odd thing is my wife works from home, and after weeks of dealing with it in the evenings, she had her first issue during the day. Wouldn’t wor

I want to change my wifi password, i’m fairly certain i left it as the default PW, but when i try to change it all i’m met with is invalid password. It doesn’t tell me the PW requirements it doesn’t tell me what is invalid or anything, and i have no way of finding out what the current password is. Can i get some help?

I need a compatible range extender for my otherwise excellent G54 Surfboard BE18000 device.  Does Arris make one?

Got my G36 up on X-finity only to have it intermittent loss of internet connection.Reading the threads it looks like this is an ongoing issue with G34 - 36 for over a year. Reverted back to my older Arris, plan on returning my G36, and research if Netgear has same issues.

My wifi has been seup for about two years now and I had no issues logging in with the old app. But now whatever I try, the new app doesn’t let me migrate because it thinks I’m not connected to the network even though I am. And the only other options are to “activate the network” which it has been for a while.

I set up and had Comcast connect, but no internet.  Everything worked before I switched modems now a steady blue light stays lit and no internet.  Help!  TIA

I am trying to connect the OrbiRSB 50 to the Arrisg34 orbi connected to the the unit does not get internet to cover the houseeverything appears to be set up correctly

Today I called Arris Surfboard Tech Support to inquire about updates for my SBG8300. The agent’s false and totally untrue answer:  “Your Internet Provider provides updates for your Surfboard modem”. Thus insinuating that I am an ignorant buffoon, which I plan to deal with later.Question: How do I receive software updates for my modem?

After activating my G34 modem I went to 192.168.0.1 to change my password and checkout the interface.  Now, a couple days later, I am unable to log in with my new password.  I get the message-invalid log in credentials. I’m sure my password is correct-what I changed it to.  User name remains admin.  What do I do?

I have to reboot everyday or my download speeds are as low as they can go

When I Googled "Is the NVG578HLX router compatible with the Arris Surfboard app", it said it is.

I just bought a G36 yesterday, activated it on xfinity last night and multiple times today it has lost connectivity. Sometimes, the modem shows it is connected and has DNS and IP from xfinity but none of my home network PCs or devices have internet access. Other times it shows connected (solid blue light) yet I can’t get on the internet or even access the admin page to check status even though I my PC has wi-fi connectivity and can ping the management IP of the gateway.I’m tempted to return this and go back to my old modem.Is this thing really a piece of garbage or am I missing something?

New G34 WIFI 2.4 and 5.0 both appear in mobile devices (laptop, iphones) WIFI settings, but no internet service is actually provided.I have: connected to GUI and GUI show devices are connected. connected via mobile app and ethernet. Modem is activated by Xfinity (Mediacomm) and they see it. Tried rebooting x3 - no change. Tried factory reset - no change.Bad WIFI Router? About to return this overly-expensive model...

I’ve got a new modem, gone through all troubleshooting steps with Xfinity they show a connection but I’m unable to access internet

Hello, the G34 is not and I don’t believe has ever connected to my iphone. I continually get the spinning/loading ball when I’m just 2 feet away from it and the speed test I have done using an app called Speed Smart is showing very very low download and upload speeds. I called my internet provider and they say the signal is fine. I’m not great at all this technical stuff either. please help. I took screenshots but I don’t see where to upload them.  

I’m considering purchasing the G34 Wi- Fi cable modem.  Will I be able to download the app to my desk top computer?  I don’t have a smart phone.

I have a new G34 wifi router. Some of my devices hook up to 5G but my iphone, ipdad, and macbook only hook up to the 2.5. My Xfinity speed should be up to 600 but only getting around 34.

Keep on saying wrong password. I am using the password that came in the box 

I just purchased a surfboard Wi-Fi cable modem AX 3000. I am trying to install it, but I do not have a cable coming into the house. All I have is Cat five cables coming in. How do I connect the cable modem to the Cat5 wiring coming in?

I can’t change my password on the app because it redirects me to download a separate app called fing which also does not allow these changes. I just want to change my WiFi name and password.
