Modems

I have just installed the S33 Modem with Xfinity.  I can directly connect to the internet via a wired connection to the modem.The modem, however is not providing a connection to the router.  I have tried several cables.  The router status is telling me that the ISP’s DHCP is not functioning properly.  Xfinity is telling me there is nothing they need to do, but the issue is between the modem and the router.Are there specific DHCP settings that need to be set up either on the modem or the router?  The Asus Router I am using is the GT-AX110000.

occasionally, my cable modem drops me from the ISP.  It generally occurs when I am watching TV.  I reset the modem and fifteen minutes later I get dropped again.  I can continue by again resetting the cable modem.  I am usually watching a movie on a streaming channel or You Tube

After just over a year without issue, I noticed my S33 has started making some high pitch noise after a reboot for the past few weeks.  I checked that it wasn't overheating, and I was still getting nominal performance, and the noise would go away shortly after it connected.However, after noticing much slower data rates today than normal (less than 1/10 my typical rate), I did a reboot of the modem tonight.Now, it won't connect at all to xfinity.  It will flash a single green led then go solid amber for about 10 seconds and repeat with a lot of high pitch noise.  Verified coax and ethernet cables are good.Prior to reboot checked through xfinity that it was connected and no outages.  Verified after attempted reboot via removing power for 30 seconds to the modem that xfinity isn't seeing the modem and no outages in my area.  Have now re-attempted to reboot multiple times with the same result.I finally decided to pull out my old SB6190, figuring I would have

How do I get phone support for a replacement modem?

My S33v2 Modem is dead, I have gone through all the troubleshooting steps and the cable company came out and confirmed that it was not work.Please send me a new one.

SB8200 with Xfinity not connecting. Says no IP address

I replaced a Netgear cable modem, I have a S33v2 and using the 2.5 GE eathernet port it is connected to an Azus GT-AX11000.  However the ethernet port is blinking yellow, my connected devices via the Asus can get 700+ Mbps, so it seems like it working fine.  But per the manual I would have expect the ethernet port to blink green indicating a 1 GE connection.   A bit confused. thanks in advnace David 

I have an Arris Surboard Model SB6190 No Wif. Need to Configure UDP Ports 123, 500, 4500 for T-Mobile CellSpot. Please help.

I have a separate property with multiple devices (security cameras, irrigation, thermostat) hooked up to my home network via wifi, and my current router just died. I am looking at purchasing a new Arris router and having a neighbor plug it in. However, for my devices to automatically reconnect to my wifi signal, I will need to change the Arris factory SSID name and password to match my current network credentials. I know how to do this when I am connected via the same network using the generic IP address for all routers, but I clearly am not going to be onsite to access my new router that way. I read that the Arris Surfboard app will allow a device to be linked to the app by manually entering its SSID and wifi passcode. So will my Surfboard router come with a UNIQUE SSID (not generic 192.168.0.1 or similar) and passcode that I can manually enter into the app accessed via a DIFFERENT wifi network to enable me to access my router to them change its network credentials REMOTELY? If it

I know it's an old modem, but it's been working flawlessly for years… until a couple of weeks ago where, sometimes, it keeps dropping connection. Trying to restart it doesn't fix anything.Anything I should look at? When talking to my cable company is there any question I should ask?

I'm not sure how to ask this question - hopefully someone will understand. One time I was speaking to tech support and I think they had me type my IP address into my web browser search bar and it took me to an Arris page where I could make changes for my modem/router. Now I can't do that or I can't remember how they had me do it. How do I access that page (account page?) again?

I need to hook my modem to my personal router can you help me step by step 

Just set up an Arris modem, it connected to my TV, but how do I sync it with my MacBook? Please help!

Hello, my s33v2 modem has worked fine for almost a year. Within the last month I noticed a high pitch shrill whine coming from it. Is there anything to do or a way to have it replaced to resolve this issue? I have the modem in my office where I work and it is very distracting. Thank you.

Internet provider says we’re connected. Network won’t show up on any device 

How do I change network name and password

Our fairly new (5 months) Samsung TV suddenly lost WiFi connection to our network. All other devices (laptops, phones) connect without problem. When using LAN cable TV works fine (but we lose WiFi capability for other devices.

I have errors in my event log on my SB8200 after enabling LAG. I am on firmware AB01.01.009.36.02_022720_183.0A.NSH , I have read that Arris has fixed LAG issues via firmware updates. Spectrum tells me they are not responsible for firmware of non-leased devices, and that I need to update the firmware myself. What can I do? Update: Spectrum says “only firmware I am seeing for that model device is for the Version 6 Docsis 3.0”

I have same thing happening with SB8200, like every week or month it would drop down to 30mbps and power cycling the modem is the only way to fix it, I am in Phoenix.

How do I ensure that WIFI is turned off (not transmitting)?

is the 8200 compatible with router tp link tl-sg108e 

Hi,Up until recently, I have been able to access the modem info via a browser using the IP address.  Recently I have been unable to do so.  I have tried all the IP addresses listed on the internet without success.  I have used both chrome and safari.  Sometimes I get a message saying the site is not secure, but even when I click “go to site” nothing happens.   Please help me access the modem setting for my SB6141 on my macbook pro running Sonoma 14.5.  Thanks

I've been trying to talk to someone on the phone or even live chat but neither one exists you keep sending me in circles this is no way to run a business but a good way to get a bad reputation all I want is to get my refund on a SB8200 that I purchased on 5/08/ 24 my order number is 59472 you tell me I can but just try getting it just give me the info I need to return it and I'll be happy, I already see a lot of unhappy people on your community site.

My S33 modem is connected to our google wifi and the other day it went from working to this amber or green ish color and nothing is able to even detect that it is working at all. My wife tried calling and the guy even said during the trouble shooting process that it might have just broken but has anyone else had a similar issue or problem and is there a work around?

We recently purchased a surfboard cable modem at walmart.  When our new internet was connected we realized we did not need the modem.  When we tried to return it, it was out of return time frame.  The return desk informed us to contact your website to see if it could be returned directly to you.  The modem has not been opened.  Can you help in any way?ThanksCindyhu
