Wi-Fi Modems

I have the G36 and my 2.5GB will not even come close to 2GB with Ethernet. I have all Cat6a cabling and switch that can handle up to 2.5GB also. When I am plugged in with my Ethernet and do a speed test I only get 359Mpbs. How can I fix this as I do not want to change out my modem again.

I'm having same issue with sbg7600, cut out 4 times yesterday. Before that it was fine.

My wifi router isnt working. Its been replugged and reset many times. Im not sure what else to do other than contact support! Im not sure what IDs or Pins are needed but please let me know and i can give any information for any help! Thank you so much

Hi purchase an Arris G36 yesterday. We are having difficulties with internet connection and I want to change the name of our WiFi and the password.

When I try to log into the modem management website, using any viewer I get a message similar to this: “Supported Browsers Versions The version of Mozilla Firefox you are using is unsupported. Your Gateway's web interface has been tested to work with the minimum version: 63.0.3.” This is severely out-of-date, since the current version of Firefox is 125.0.1. That’s problem #1. The main problem is that it’s telling me my login credentials are incorrect… but giving me no clue how to fix that. It doesn’t offer the ability to change my password, doesn’t offer email verification, offers no help at all. After several attempts using different passwords (I have about 3 “registered” with Arris), it locked me out of my own management page. I appreciate security when it’s good, but this is seriously outdated and poorly designed software. Does anyone have a suggestion on how I can solve this problem. Calling Arris “support” wound up in their automated system repeatedly hanging up the phone instead

Hi all, I am using an ARRIS router model NVG578LX provided by an internet provider. I need some help on how to turn on the 2.4GHz channel with wireless IEEE802.11b/g/n standards. It is because my desktop doesn’t have a built in wifi adapter hence I have to use an Edimax usb which only works with the IEEE802.11b/g/n standards. I have successfully turned on the 2.4GHz separated from the combine channel (the primary). I also tried turn on and off the 5Ghz. Unfortunately, the Edimax usb couldn’t find (see) the 2.4GHz network. Noting that: All the phones and laptops can find/see and access to the 2.4GHz. I also tried to turn on the Guess wifi with 2.4Ghz (but the Edimax coudn’t find/see the network). the Edimax usb still can see other network providers from the neighbours surrounding. the Edimax usb worked well with the previous internet provider using a different router (not from ARRIS) but only when I turned on the IEEE802.11b/g/n standards using the settings. it seems this is the key iss

The surfboard app is only showing 2 devices on my network which is not correct. App appears not to update or show/display any correct information making it essentially useless. Also experiencing connection issues including devices randomly disconnecting from the network then not able to locate G34 to connect. extremely frustrating and poor customer experience at this point.

Why do my arris sbg10 keep disconnecting from my internet

My kid for weeks now has been having issues with the WiFi but I’ve been chucking it up to plaster and lathe house and distance from router. I just tried to print something from my phone while on the 2.4Ghz WiFi which worked in the past but was having issues. This lead to me removing the Ethernet cord from my computer and trying to connect my computer to WiFi. Upon running a speed test on speedtest.net, I was getting 5Mbps, if I’m lucky, while the 5GHz gives 300+ Mbps and Ethernet 500+ Mbps. I saw similar posts talking about changing the channel so I tried that and the best outcome was 30Mbps. Is my Surfboard SBG7400AC2’s 2.4GHz WiFi components shot? Did I hit the side of it or something to cause damage internally? Why is it so much slower? I get WiFi is supposed to be slower than wired but not to this extent. What can I do? Does Arris have an address to diagnose your router or something?

I got a SBG8300 and I reset it cause it was running slow and now it’s stuck on the blue light and it don’t even let me reset it again. I unplugged it overnight and still the same thing. Any help would be appreciated.

I have the Surfboard Central app on my phone and I listed all my kids devices by name and type and put them under User Profiles for Parental Controls. Then I turned them all on but the children’s devices are still synced with the internet. (The toggle button indicates that parental control is enabled). How can I solve this issue so the parental control actually works? I only bought my modem in June 2023, so it shouldn’t be too old to function properly when it comes with a 2 year warranty.

Replacing an older modem/router that was continuously dropping the connection. I finally got the connection to work, but now I can not get access to the gateway to rename the hardware or to change passphrases. Does this require a factory reset?

How can I change the password that came with the modem?

I installed the SBG8300 modem/wifi router yesterday. Connected devices are working great. I logged in the GUI and can see the connected devices, nevertheless the iPhone app shows “00” devices. I have restarted the modem and it does not fix the issue. What is interesting is that the web GUI shows all the connected devices, but not the iPhone app

Why do my SBG8300 Cable Modem & Wi-Fi- Router keeps disconnecting from my internet???

I set up my g54 for port forwarding but ports are still shown as closed on port checker.

I just tried to activate my modem and Cox said they couldn’t because this model only goes up to 250 Mbps???

I need to replace the ac adapter for the sbg 8300, but the materials that came with the modem/router don’t say what the device’s rated voltage and current are. Seems like the ac adapter would need to be 12 volts and 2 amps, but I used an ac adapter with those specs with this device and that adapter got fried and stopped working. Is there more information I need to select the right adapter? Can someone please confirm the ac adapter and/or voltage and current specs for the sbg8300 so I can make sure to order the correct replacement? Looks like Arris doesn’t offer ac adapters, just uses third-party ones. I want to make sure it’s compatible and pricing and info for ac adapters is all over the place and inconsistent. Please help!

How can I login again after being locked out?

I know the SBG8300 is an older unit, but it has served me well for several years. It is powered via a large APC UPS so it is not connected directly to utility AC. I hard-wire (ethernet cable) my modem->desktop to maximize internet performance (Xfinity). Event: I was working online during a thunderstorm with LOTS of lightening. In a moment, my internet connection failed. I looked at my modem and it was DARK. My UPS was nominal and my desktop and other accessories were operating normally. I tried unplugging the Arris modem and waited 30 seconds to reboot. Immediately upon restoring power to the modem I noticed BOTH BLUE lights blink 5 times then the modem went dark again. I tired a hardware reset (small hole in back of unit) and received the same result. I tried unplugging then restoring power again and got the 5 blue blinks then dark again. An exhaustive search for this troubleshooting indication was fruitless. I suspect an electrical surge found its way up the COAX cable which fried th

I am trying to go in and change the my network name through the Surfboard Central app. Even though I have internet/wi-fi the app won’t let me change the network name. It says “Access to your Network is currently unavailable”. It then advises to do the onboarding to reonboard the gateway. The other option is try at a later time, connect to SURFBOARD network as the remote access is currently unavailable or power off and then on. I have tried the first and third option. What should I do?

Pretty simple. I was setting up my 7600 surfboard, and it never prompted the activation sequence. So, I called Spectrum, and they informed me that they cannot activate it because it is not on their list of approved modems, routers, or modem + router combos. Please. If there are any website editors here for Arris. PLEASE REMOVE THE SPECTRUM COMPATIBILITY CLAIM FOR THE 7600 MODEL. It no longer works and I wasted nearly $200 on this piece of junk. If any officials read this, please contact me, this straight up is NOT okay.

My modem router connects to 2 different SSIDs: SB8300-BBB and SB8300-BB8? There something wrong with this model. Do I need to change it?

I would like to claim warranty on my Arris g36. Mines messed up and I did everything to fix it. The light is stuck on amber and I hit the reset button but it’s not doing anything.

I have a G 34 surfboard and I’m having major problems. The first one being it is saying that my Internet speed is lower than 100mbps. I have Dan several different speed test and they all come out the same. In addition to that I cannot get Wi-Fi connection on any of my devices like my printer and all my Apple products. Any assistance with this would be greatly appreciated thank you.
