I recently installed a Surfboard G34 wifi cable modem and it is losing connection multiple times a day. Sometimes it reboots itself and regains connection. Sometimes if I unplug it, it will restart and reconnect but it’s happening multiple times a day. I went through troubleshooting with Xfinity and they couldn’t identify anything remotely. They can send a tech out but they’re not sure if it’s an issue on their side. I’m trying to see if I can troubleshoot the device before having a tech come out. Can anyone help?

I just purchased this G36 modem/router today and installed it. Went through all the nonsense on the app and on internet providers site. It worked for maybe 10 minutes and stopped. The app says it is offline, the light is flashing blue and devices are or were still connected to it via WiFi. It’s not connecting to the internet. I’ve restarted it several times and it goes right back to this.what’s the issue?

Arris model G36 purchased last month. Had tough time setting up via Xfinity and had to speak with Arris support who reset it and then back to exfinity to register it again.  Now need to put in Bridge mode but when go to 192.168.0.1, I use the email address I registered under but no idea what password to use.  No matter what I use, cannot get past error for incorrect email.

I set up the modem and it worked well. I connected my TVs to it. But the connection didn’t reach to the far end of the house, so I set up an eero connected to the modem and then I set one up on the other side of my house. Since then, it has not been working, and any time you’re connected to the wifi, you cannot access anything without it popping up with something for Xfinity

Completed the setup, updated the password for the portal login in the process, and after reconnecting the new ssid’s, I am unable to log into the portal. I’ve done this twice. The first time, I figured I forgot the password, so I reset the device and went through the setup process a second time. This time, I’m confident the password is not the issue. 

How to disconnect 5G from modem

I just swapped out on old cable modem for a G36.  Everything seemed to be working the first few days. Then Spectrum internet went out in my area. Called Spectrum, they said everything was now fine on their end. Eventually the 5G network came back, but nothing connects to the 2.4 network. I have some items that can connect to 5G. I really don’t want to go through all the items connected to 2.4 and switch them over to 5G or replace them with items that work on 5G. What do I need to do?

I own a DOCSIS 3.1 gateway G34 with 1.04 firmware known for intermittent connectivity issues that are fixed by 1.05 firmware.  This device is on the Approved Device List from Breezeline.  1.05 has been out for 3 years and is stable.  However despite the DOCSIS mandate Breezeline customer service refuses to manually update the firmware saying any new firmware will be automatically pushed and my only solution is to ditch my gateway and rent ISP’s gateway and pay monthly rental fees.The connectivity drops predictably every few days, probably by algorithm to encourage me to rent their equipment.Do you see this behavior at Breezeline or other ISP?  Is there a tool to exam and document the connectivity issues are man-made by Breezeline?Is this a legitimate case to file a complaint with FCC or class action?

Every few days, the Modem stops the Internet connection, and the only way to reset is to unplug and restart.  This is not due to power failures or any other issue.  It is happening 1-3 times a week and is a real problem  , I am with Xfinity

How do I change the password for one of my internets in my g36 arris modem 

I recently purchased a G36 Surfboard Wi-Fi Cable Modem to use with my Xfinity internet service.  Since I installed the modem, I have experienced multiple daily internet downtime.  Xfinity can not find any issues on their end.  Could something be wrong with the new modem?Sharon Cooper(Edited personal information) 

My ARRIS (G34) - Cable Modem Router Combo - Fast DOCSIS 3.1 Gigabit WiFi 6 (AX3000) reset itself back to it’s factor settings. I can’t login to change this. I tried to get the password reset to email what to do, but nothing is showing up. Ideas?

What happened: I was troubleshooting a Xbox Live issue my son had with his Xbox. One of the troubleshooting steps was to put the G36 in bridge mode. Apparently bridge mode wasn’t the solution and I wound up having to do a factory reset.Problem: Now trying to use the SURFboard Central App, I can connect to the 2.4GHz and 5GHz on my phone with the default SSID/password but cannot connect to other devices.  Troubleshooting attempts: I tried using the (192.168.100.1) to see if I can change it there but it doesn’t load for me. I WOULD log off and log back on but I don’t remember the password to the app and I couldn’t find the forgot my password option.End State: I’d like to be able to change the SSID/password and use the app prior to factory reset. 

When I try to sign into the modem via browser it says to use the email address I have for the app. I have used that and the password and it still won’t let me in.

how can I tell if I have the latest updates on mt G36?  I have internet drops, freezing frames and audio drops. 

My G36 over the last few days has been constantly disconnecting and apparently shutting off entirely every 20 minutes or so. The blue light goes off and I have to unplug, wait, and plug back in for it to work again. This only works for 20 minutes or so and then it happens all over again. It's happening totally out of the blue, everything was fine until a few days ago. I haven't moved the unit, it hasn't gotten knocked over or damaged at all, and I'm at a loss 

I have an Arris Gs6 SBG00DAE36. It is only a year old. I am experiencing Comcast/Xfinity dropping connecting to the point where I can hardly stream, use my phone, nor Zoom. Of course Xfinity blames the Gateway, but is is really? How do I figure out this puzzle?

Can I connect my arris up to my Eero? 

I have a Chromecast and 2 Chromecast-compatible TVs and numerous devices that connected before we changed router. The TVs and the chromecast have no trouble connecting to the same WiFi but no devices are ever found. Also the TV’s app has a remote control option that also stopped working since we changed router on all devices.  I set the firewll to custom and made sure casting wasn’t blocked. I even turned off the firewall. Still no luck. Any suggestions?

I recently switched to xfinity 2 gig plan, bought the G36 router with the 2.5 gig port, using a CAT 8a wire from the router to the computer, but I only get 800mbps-1200mbps, not the full potential. Already spoke with people in xfinity in person and online, both say that on their end I got the 2.0 gig plan. What could the issue be?

The Arris G36 was dropping the internet daily even though the blue light was on when there was no connection and I cycled power often for it to work.  The signal power is ok. When internet worked WiFi was ok.  The ISP tech said my connection problem was that WiFi was turned on at my end but the Cable company had WiFi turned off from their end.  He turned it on and it has worked for about 6 hours now.  Is it likely that this will fix the problem long term?                                                  I asked about modem updates and He told me that user owned modem updates are not done by Mediacom and must be obtained from Arris by the customer.  

Hi my problem is since I just installed G34 modem I cannot goto craigslist.org  through wifi. I can by going through my data connection...with wifi off. Or in wifi using VPN so that tells me it's something with my IP address...I turned off the firewall thru arris gui I tried both the ip4 and ip6 still no go...anyone here have the ARRIS G34 do you have trouble with that website....or is it just me...I only surf that site for motorcycle parts so if CL blocked me I have no idea why.Thanks.

Please advise the paper work to file a warranty claim on G34.

Bought a G36 and after 60 mins of my ISP support, it doesn’t work, won’t provision. Calling Support (Edited private information) or (Edited private information) FAILED. A couple of rings, then the call dropped with both numbers. I’m sick and tired of companies being INaccessible. I will NEVER buy anything ARRIS again. No support available. Life isn’t M-F for network or hardware issues. They will hear from me tomorrow via chat and it’s not going to be fun AFTER the first 30 minutes. I’ve had this G36 for 1 year AND JUST CONNECTED IT TODAY. I travel with my job 9 months out of the year and it’s out of warranty as of July, 2025. Since it was never going to work to begin with, it seems that ARRIS owes me $. I have a newsflash for ARRIS who says on their website that they stand behind their products!
