Wi-Fi Modems

I have an SBG8300 and it is constantly blinking. The online and wifi are both blinking. I have tried unplugging rhe coaxil and power multiple times but it just does the same thing every time. I have also tried the factory reset button and it still does nothing. I let it sit for hours expecting it to eventually settle but it continues and I dont know what to do.

Attempting to help by clarifying a couple of things that I saw from an earlier post that has since had the comments ability turned off.This unit does not contain what we Xfinity users have come to know as eMTA jacks on the back to handle voice service directly from Xfinity.  I used to have Xfinity voice service but several years ago migrated over to Ooma.  The Ooma device, depending on which model you have, will either be ethernet only or ethernet/wifi.  I just activated my G54 unit last night but have already found that my Ooma device, connected by ethernet cable to one of the ethernet jacks on the back of the G54, is working as expected for both incoming and outgoing calls.  

I am trying to hookup my modem to a coax circuit that already has service and a modem with AT&T. AT&T support has said that I should be able to hook the modem up and it will work. However I am getting an Xfinity activation pop-up, which is the ISP I had previously.I am not sure what the issue could be, but can these modems be pre-programmed for a specific ISP? I bought this a while ago and do not remember what I had done at the time.If this is just not possible to do then that would be helpful info as well.

My internet company gave up on trying to help me.  When I try to connect to my network I get an error message that says “This network is operating on WiFi channels in use by several other nearby networks.  “  Tells me to try restarting my network and maybe it will help.  I restarted 4 times… same message.  Help

I am wondering if the G34 Wifi modem supports WDS? I have a second router that can support WDS, but I cannot find the setting for it on the G34.

My SBG8300 modem/router has worked fine with Xfinity for a month+, but now provides no Internet access even though both status lights are solid green and Xfinity shows no outage and good connection to the modem. I have tried disconnecting the cable from the wall and modem during several restart attempts, but the problem persists.  

For the past week, the wifi has been terrible. Our phones/iPads keep disconnecting. All our smart home devices are fine and any hard-wired/ethernet-connected devices work just fine. Both of the wifi symbols (bottom two) on the device blink constantly. When I check Xfinity it says service/connection is fine. I’ve done multiple hard resets and still no change. The disconnect is random, too. Sometimes when I restart a device it will connect to the wifi, work for a bit, but then cut out. Other times no matter how many times I restart the device, it won’t connect to the wifi (prompts me for wifi password, which it then says is wrong when it isn’t). Any help/advice would be greatly appreciated. Thank you.

I can’t enable the bridge network on my G34 because it’s asking for login credentials and I was NEVER prompted to create a user password when I set up my account HELP

Is there a modem that you can see what websites have been used each day?

I have the same unit, and I agree, it’s pretty mediocre.One thing I learned about reserved addresses - they MUST be within the DHCP lease range.  If you have them outside of the range (which of course is what everyone normally wants), then when the lease time expires, the reserved address is dropped, and a new one is supplied from the DHCP lease range.  So, in effect, your desired address is not really reserved!!!One of many other problems is that the client list is often missing entries.  Every time you refresh the page, you get a different list of clients.  No apparent pattern, as far as I can tell.

I have an unknown device connected to my device that I suspect is not in my household. I have tried to block it but it still shows up in my Connected Devices list and I can still see a connection. I need it removed, please.

This is a known problem with the G54.  I get Constant disconnects all the time.  I have 2 G54s and I’ve got a friend with 1 as well.   1 of them is at my home with xifnity, the other is with Utopia fiber, which is 40 miles away.   My friend gets disconnects all day long and I get disconnects all day long on both of my G54s.  I have spent hours and hours on the phone with xfinity, Uptopia and Arris support.  Both my ISP providers have updated the firmware, have replaced all the cables, connectors, etc.  Even Arris has replaced one of my modems thinking it was a bad modem.  I’ve tried doing factory resets, changing channels, disabling the wifi and NOTHING works.   I know for a fact that it’s something with the modem because my friend can’t get his to work correctly and I can’t get either of mine to work correctly either.  Now I’m past the point of not being able to return it and it’s very frustrating.  I can take my old 7 year old Linksys modem and reactiva

I have a G36 I bought a little over two years ago that I use with Comcast.  I haven't had any issues with the modem.  The only previous issue with connections turned out to be a cable that got damaged by my neighbor.  Comcast replaced the cable and all has been fine. Today it lost connection but the light was still blue.  If I disconnect power and reconnect, it will work briefly but then drop connection again.  I have 3 devices connected via ethernet and a bunch on WiFi.  I've disabled WiFi with no change.  I also disconnected each of the ethernet devices individually with no change.    Comcast doesn't detect an outage in the area and their AI support says things look good to my modem.  It can reset it successfully and see when it's not online if I disconnect it.  Gateway FW version is [edit personal information] NCS Anything else to try?  Hate to have to shell out for a new one when it's only a couple years old.   

Hello.  I am using an SBG8300 to connect to Xfinity.  Most of the time it works just fine, but several times lately the download speed has dropped from 45-50 Mbps to under 5Mbps.  If I unplug the modem, wait a couple of minutes, and plug it back in, everything returns to normal.The Xfinity service doesn’t appear to be the issue.Any idea what this could be.  I purchased the modem less and a year ago, so it’s still under warranty.The last time I’m aware of it happening was last Wednesday and Thursday, but I was away over the weekend.  It hasn’t happened today, as far as I can tell.I’ve downloaded the logs from the model administrator panel.How do I proceed from here getting technical/warranty support?Thanks.

I just purchased a Arris C335, my cable Co already activated but while i was connecting my tv it connected to the the Wireless but not the internet.I already did the troubleshooting through the Surfboard Center as that's where i was instructed to do my who activation but all those many troubleshooting has no resolve the issue.

When I opened the app it said it needed to be updated on a G54. I began the update but it’s still stuck at 0% and has been that way for the last several hours. Can someone help?

II purchased a I purchased an Aris surfboard G 34 router a week ago. But now, when I connect a device to the 5G Wi-Fi works fine. When I connect device to the 2.4 G Wi-Fi it does not get Internet.  I have an ethernet plugged in Verizon cell signal extender that worked up until this afternoon.  Now it does nothing 

My brand new Arris 54 is unable to maintain 2Gbps speeds on Xfinity residential 2Gbs service.  If I reboot the G54, I’ll get excellent 2Gbps speeds of 2200-2300 speeds, but very soon after that I can only erratic speeds from 200-1200Gbps.  Using Comcast’s modem, I consistently got 2200-2300 Gbps download speeds.  What’s wrong with the Arris G54 

Seems like a recurring problem in the community security warning accessing the portal. Please provide help accessing the portal while the browser reports the SSL certificate is unsafe. What work around exists that is not beyond my technical capabilities! New box installation and have already had to work around the Surfboard Central App registration failure. 

Arris login page doesn’t. Won’t allow entry of new password. Keeps saying unexpected error. Does Arris actually offer any real customer support? 

Happens about 4 times per day, any solution other than rebooting gateway?

I have the G34, the first week I bought it, it worked great but now 2 months in the service is spotty. I have had to call my service provider so many times. I have tried rebooting and all. I do not know where to go if check if the software is up to date. I will like to use the service I am paying for. Is there a phone number to call for someone to help fix this issue?

I’ve tried enabling upnp and port forwarding and my nat type is still strict.

I purchased this wifi modem almost 2 months ago and still not able to connect to the internet.  I have been dealing with Comcast and they tell me that the modem shows on their system and there is a good connection.  I have reset the modem numerous times.  Any suggestions?
