I lost my software license paper for my s33 modem. How do I get it back?

I bought a s33 modem about three months ago from Walmart. I've been lazy and didn't bother to hook it up but of course I want to now and I can't find the software license. What do I do to get that back?

SSL/TLS Errors after installing new Surfboard S33v2

I just installed a new S33v2 and ever since, I’m getting SSL errors. The cert on the modem itself is bad, not expired but I guess not trusted. But I don’t know why that would have anything to do with certs passing through the device. FYI, all incoming certs appear to come from my SP (Cox) instead of their actual origin. I can ping out but can’t connect to anything using SSL or TLS, which is pretty much everything now. Any ideas? Thanks,Tom

Spectrum says SB6183

Everything worked fine. I was rolling off a promotion and Spectrum a new one on my account. When they did it, they said my modem is no longer compatible and I have to buy a new one. Is this correct? And what’s a cheap SB I can buy if I need a new one? Thanks

SB8200 fails to connect immediately after power cycle, continued

My SB8200 will not work immediately after a power cycle.    It must be left unplugged for 15-20 minutes before attempting to reconnect.   The modem is noticeably warm when unplugged, and cold (cool) 15 minutes later.  This problem is very repeatable.   I’ve never had it connect immediately after power-down or reset in over 20 attempts over the last 3 months. Other than this one issue, the modem works fine.   What circumstances would create this behavior?  I need someone to explain to me why this problem is not a hardware issue…When plugged back in immediately, the modem will get to the point where the top three lights are solid green but the bottom one is blinking green.    It will stay like this for 2 or 3 minutes (I’ve not timed it) before resetting.   The start-up sequence repeats, ending with the same condition (top 3 solid green, bottom one blinking green).   This repeats for at least an hour (that’s the longest I’ve given it).I’ve been on the phone with Arris support 5 times and

Arris S33 modem dropping DOCSYS 3.1 connecton wo XFINITY GB service

For the last few weeks, I have noticed my Arris S33 Cable modem has been dropping the DOCSIS 3.1 connection (solid blue LED) to XFINITY GB service and reconnects at DOCSIS 3.0 (Solid green LED). It’s still pretty fast but I take exception to XFINITY providing LESS service for more $, Is anyone else experiencing this DOCSIS 3.1 drop with Xfinity?BTW, I’m in Tucson, AZ

Arris Surfboard S33 not working

Arris Surfboard(s) not workingBeen using an Arris Surfboard S33 for a few months now and have had no issues until today.    Came home from work and suddenly it seems like it’s bricked or something.    All three LED (green, blue, amber) indicator lights are lit up, leaving a yellow-ish solid light that never changes or blinks. It’s completely unresponsive and I am unable to connect to the internet.    The lower Ethernet port on the back has lights on while the top one does not. Plugging the Ethernet to the router into either one does nothing and neither does hardwiring my PC into either one.    I know the pics shows the coax unplugged, but that was just to capture the lights easier.  Using a pin to reset the modem does nothing. Tried for 10/20/30sec and no dice.  Title is plural because I went out and bought a second one thinking the original one was just faulty, but upon giving it power, it does the same exact thing.    I never plugged the second one into coax so I don’t think it could

Loosing full speed on account

I have owned this Ariss SB8200 for several years. No problems. SP is Optonline. No problems. A few months ago, I received an upgrade from my basic service speed of 100mbps to 500mbps. No extra charge. Long story not worth going into. I am just starting to concentrate on solving this problem as I haven’t needed the speed.My problem is that I keep reverting to my 100mbps speed. I have done all the regular checks and tried different cables and connected directly to the modem. The issue always comes back to the fact that after several hours or days I suddenly find my speed back to the old 100mbps. Rebooting both modem and router in the proper sequence always gives me the full 500mbps for a finite time, then it reverts to 100mbps. The same when connected directly to the modem with the computer. The time it takes to revert is never the same.Is there something I should do to the modem to solve this?Thanks for any help.Regards,Dmin11

Intermittent internet connection and LED light is blinking

Everyday for the past 4 days around the same time our modem loses connection for a couple hours and has the blinking green light. I’ll attach a picture of the modem page and what it’s telling me. Our ISP is Comcast if that matters. Haven’t had any before this.

No internet on SB8200

My old modem and router were both functional (slow and outdated) before purchasing and installing the new Sb8200.  Now I spent a few hours online with my internet provider and still have no internet with the sb8200.  My internet provider tried everything they could to get it to function, now they tell me I’ll have to have a tech look at it and if the problem is on my end there will be charges.  It’s obviously on my end, everything was fine (slow but functional) before I installed the sb8200.  What else can I try to make it work?

S34 - Timeline for release of this modem

On both xFinity’s website cable modems section and CableLabs approved modems list is the S34. CableLabs shows a CQ date of 2024. Does Arris have a timeline for release of this modem? If so, I’d prefer to stay with the brand instead of upgrade to a competitor.

SB8200 Xfinity only 1 upstream locked channel

My SB8200 and SB6183 only get one upstream locked channel at 35.6Mhz. I see many posters have 4 locked upstream channels. How have other folks resolved this issue? Channel ID Lock Status US Channel Type Frequency Width Power 4 Locked SC-QAM 35600000 Hz 6400000 38.3 dBmV  Also the SB8200 on power-cycle takes 18 minutes to lock the upstream channel. The upstream channel tests 16.4, 22.8, 29.2 at different send power levels, till it reaches 35.6 and acquires lock. Has anybody else faced this problem.Power cycle timestamps are mm:ss.01:00: WebUI comes up in 192.168.100.1 01:25: Receive LED steady green, send LED flashing green. 01:25: Downstream channel locked 49.5Mhz, 13 dBmV, 44dB SNR. 01:25: Upstream parameters acquired. 01:26: Upstream channel 22.8Mhz, 48.8 dBmV. 05:25: Upstream power oscillates like th 59, 49, 38, 28, 61, 51, 46, 41, 31, 64 dBmV. 12:11: Upstream channel 29.2Mhz 14:08: Upstream

Fast to slow in a minute on S33

My S33 starts out getting 550mbps then drops to 30mbps within 60 seconds.  Switched to a hard line to no effect.  Repeatable issue.
