Solved

Hello, I would like to know how to manage port forwarding on the T25 Modem. Thank you.

I have the same problem with the 8300 model.   I don’t have access to the devices I want to block so can’t adjust parental control settings or address settings and they seem to continue to connect even if I change the passwords and reboot. Also the surfboard app shows devices connected to a different channel than what they are logged in on. 

I am trying to set up the modem app for my new modem on my computer.  Have it on mobile, but as I am slowly loosing my vision and it’s hard to see most apps on those small screens.  Why can’t I find an install for the computer?  Am I just not seeing it (no pun intended).  Are you able to help with this request?

Can i use S 33 modem with a 300 mps internet plan now. Possible upgrade to 1 gb plan in future..   

Just tried to set up our new G34 and cannot figure out how to reset the network name change the password or set up parental controls with the app. What am I missing? 

Does anyone know if the arris G54 is compatible with Atlantic Broadband (now Breezeline in New Hampshire)

looking for the latest firmware for DG2470A gateway

So I was using my internet as normal when I all of a sudden lose connection, look over at my modem and it is power cycling, first power lights comes on, all lights under light up and then they all turn off and it repeats. I don’t have any extra power cables for this so I tried the one from my Phillips hue bridge and same thing. I’ve tried to unplug the modem from the wall, tried a new outlet, kept it unplugged for some time and replugged back in, I’ve also tried the reset button on the back which is when the original power cable stopped working completely. Is this just an issue where I need a new power source or is this thing messed up? I work overnight and need to be on ASAP but can’t figure it out. 

I have Xfinity 1000 down/100 up plan for over 3 months. I am connecting PC direct to SB8200 for testing and I only get a max of 24mbps upload. Only 1 (new) splitter and no other breaks in the line to the outside box, which has a new cable to the pole. Download is to spec and fine with no errors.Online Xfinity has reprovisioned the SB8200 at least 20 times and rebooted it at least 30 times over the last 3 months and I’ve logged around 22 hours on the phone with them.An Xfinity tech came to my house and tested everything and said it was all 100% and the reason I wasn’t getting 100mbps upload was likely to be Xfinity not provisioning it right.He verified upload 4 bonded channels at 45 dBmV within spec.To rule out the SB8200 I bought an S33 and had exactly the same result so I returned it.When I call them Xfinity is now telling me that the problem is the manufacturer needs to update the modem and they can do no more troubleshooting until that is done. I don’t know if that’s true, or a cop

Bought the SB8200 on Amazon in February and it said two year warranty. Arris website says it has to be from Arris.com or authorized seller to be valid. So, is Amazon authorized? It’s starting to lose connection after working fine for 7 months. I see others having the same issue, must be built it obsolescence or lack of quality.

hello, when will my wpa3 update for my svg2482ac, my apple phone is telling me weak security.

Hello - I recently purchased an S33 and have it configured as follows: Spectrum -- S33 -- SFP+ -- Unifi Dream Machine Pro WAN port The SFP+ is a 1-2.5-5-10G model from Ubiqiti. This configuration works just fine when I plug into the 1G port of the S33.  However, when I plug it into the 2.5G port, I get….nothing...no LEDs light up on the Unifi port at all.  The LEDs on the back of the S22 are solid green and amber.  I have tried multiple cables (currently using 0.5m of class 6E), rebooting both the modem and the router, etc., but nothing seems to work.   One other thing that might be relevant is that when it was originally provisioned it was done on the 1G port.  I called Spectrum, and they said that provisioning one port or the other wasn’t something that they did anyway. So, the question is:  how do I “enable” the 2.5G port? Thanks for your help!!

Surfboard t25 is only working in one Ethernet port reset it many times and still only pone port working 

Modem purchased May 17, 2022.  Worked until recently when internet connection would drop several times a day.  Resetting modem several times would restore connection.  ISP checked their equipment and replaced incoming cable because speed was a little slow.  This did not solve problem.  Due to visitors arriving in a few days I purchased a new SB8200 and this resolved problem.  Original modem was purchased at Walmart for $169.00 but they were out of stock when the unit began to fail and replacement was purchased at Best Buy for $138.99.  Both retailers told me to contact the manufacturer to recover the replacement purchase cost.  How do I proceed with this warranty claim?

Modem is a couple of weeks old.  Was working fine.  I went to get into through my web browser like many other times and now this error message stops me cold when I put in my password…."Can not get password for admin from backend!"  What is up?  Tried power off and on. etc.  I have good connection internet with Wowway cable and both 2.4 and 5.0 are fine.  I just cant get in.  

New owner of G36-44F1 and I need to reset router frequently to access my Netflix, Prime, etc…I have a Samsung TV & Phone in case that info is needed. Please advise on what settings I should have everything on. Thanks!

I purchased the 8300 from an online marketplace. The seller seems to have setup the login credentials which I don’t have access to. How do I go about setting up a new user id and password on the App so I can access the router settings?  

Hello All,I just bought the SBG8300. I am getting 570 MBps on Ethernet direct to Modem, and 70 MBps to Wifi. Spectrum 500 Plan iMac 2022 - 10 feet from router  Connected to 5 GHz No other devices connectredI see this complain in this community, but there is only a single reply and no conclusion. Googled it too. Thanks Everyone! Bill 

I am not sure if this is the right place to ask this question, but here goes.When I log into surfboard central and under “My Devices”, they are all listed, but I cannot tell what all of them are.  I can see my computer and my cell phones, but all the others I cannot identify.  How do I tell what the devices are so that I can name them so that I will recognize which device I am working with?

I have a SBG10 and it does connect to xfinity, but it is painfully slow.  Is something misconfigured?  My xfinity connection worked fine when I was using the xfinity modem, but is now very slow when trying to connect with my SBG10.

I posted in here a few months ago about some trouble I was having with my S33. Xfinity ended up coming out and replacing the line from the box to my house and everything has been great until a couple days ago.The random reboots are back. I spent about 3 hours on the phone/chat with Xfinity and they are telling me nothing is wrong on their end and that I needed to contact Arris. I have no splitters or anything else in the way. The Xfinity guy ran the new cable into the basement. We put a brand new coupling on the end, and a brand new cable running to the modem. That is the only coax I use in the entire house. The line from the street goes directly to the modem.I am not sure what is causing these new random reboots, but I suspect I just have a bad modem and need to get a replacement. Its pretty easy to find S33 random reboot topics on the internet, but not a whole lot of fixes.Hopefully someone on here can steer me in the right direction.Thanks

I have been getting 80-120 Mbps on a 1200 Mbps Xfinity service. Yesterday I was told my old Arris is no longer supported, so I replaced with a new Arris S33. My home is 2 stories and ~3500 square feet. My modem and router are upstairs in a bedroom centrally located. I have a Deco M5 Mesh network with 3 stations - one in the bedroom upstairs near the router and two downstairs to reach the rest of the house. With the replaced router, I get 350Mbps in the bedroom and directly below it when testing speed on my iPhone 15 and brand new HP laptop.  I am unable to get my laptop to recognize the Ethernet network when I plug directly into the Arris modem, but it works fine when I plug into the connected Deco router. When I move into the bonus room over the garage, the speed drops by 65% to around 120Mbps. There is an electrical fuse panel below the bonus room and past that panel is where the speed seems to drop significantly. I have run all of the power setting tests that I found in a moderator

I need an Arris DOCSIS 3.1 dual-band 2.4/5GHz WiFi cable modem, as recommended by Service Electric. Not sure which model offers those features. Can you point me to the right one(s)? Thanks!

I used the 192.168.0.1 to access my Arris SBG8300 Admin dashboard to change my wifi passwords. I wqs able to successfully change 1 PW for my 2.4G but as soon as it changed I lost wifi and access to the portal. I called xfinity to aak them to relink my modem using the new PW but they said “not my problem” basically and that bc I don't have an xfinity modem they don't have access to help. I need to get access back to my admin and reset my login PW too bc I realized I may have done all this wrong. So essentially I changed 1 wifi PW when I have several attached to my account ie: 5G, guest accts etc. So I’m at a loss on what to do bc none of my devices will now log back into admin. When I try I get the “ safari, couldn’t open the page because the server stopped responding” error every time. Help!!!!
