ARRIS/SURFboard → SB8200 32x8 DOCSIS 3.1 cable modem - Feedback and Results thread

I keep trying to edit that and the pics get more out of order... Well.. You can figure it out hopefully..

Im too tired right now to redo it.

Be careful; many ISPs and for that matter web providers cache requests in such a way that the second or successive requests will be faster than the first.

Well with it now being on the approved list for Comcast as of this morning, there shouldn't be any problems now.

I wonder if Amazon is still gonna ship tomorrow ? You guys that preordered make sure to let us now once it ships.

I will edit my pics and fix that tonight and add charts. Sorry, really busy work days.

I had an amazon pre-order that I had placed last month that said late Jan, then feb 18 then 22 now 24. About a week ago I killed my Amazon order and ordered from Arris direct. Shipped next day via ground. I've had it up and running for a few days now and it seems pretty bulletproof so far.

Mine is still showing shipping tomorrow, but receiving on the 28th. It's going to my place of work, so I'm expecting to get it Monday at the earliest, but Amazon is saying I'll get it on Tuesday.

EVERYBODY should post what modem they were using and check levels and stuff and then post the SB8200 levels and stuff. If you can use Multiping or pingplotter run that for a bit before swapping modems and report back here where you tests shows and what your subjective experience between the 2 was.

Ok some charts. I spent 3 hours tonight swapping modems and testing. Calling the cable co a bunch of times and swapping modems. All my charts are using the same test setup and I just swap modems live while the chart runs. The swaps are the red bands.

I have A LOT more charts and tests to post. But these will start us off.

The choice between the SB8200 and CM1000 really comes down to hardware for me. I like the hardware and buildquality of the SB8200. It also has a dual port which can later be used as a dual link providing 2 Gbps VS the CM1000 with only 1 port that is forever limited to 1 Gbps.

Either modem is a good choice. I just prefer the SB8200 because it appears to me to be a better build with fewer parts and better design. I could be wrong I suppose. But that can be debated in the thread ahead.

Conclusion for testing ? I cant find any performance difference between the CM1000 VS SB8200 doing my tests using IPv4 and 32x4 on a Cox Ultimate tier of 300 D / 30 U. Both modems did their top speeds every time I tested. Ive run the SB8200 for days under test and found no issues at all.

These are quick summary charts. I will in the next few days post more in depth charts and tests..

These were all done at 10 hz - 10 tests a second.

TCP tests.

Hmmmm... Amazon now shows "Temporarily out of stock. "

Hmmmm... The Mystery deepens. Did they ship ?

Amazon is probably showing that as all of the units that they may have had were used to fill all the preorders right now.

We will have to see if people who reordered weeks ago get shipped.

Amazon might have also just given up on a date and just changed to this.

My guess is Amazon gave up.

Nonsense - I've never known them to, and it's marked:

Temporarily out of stock.

Order now and we'll deliver when available. We'll e-mail you with an estimated delivery date as soon as we have more information. Your account will only be charged when we ship the item.

Ships from and sold by Amazon.com. Gift-wrap available.

I mentioned that the CM1000 rollout went almost exactly the same way.

If/when Amazon truly gives up it will be marked either "Note: This item is only available from third-party sellers" or "No longer available."

Amazon doesn't take backorders for product they don't expect to be able to source.

That CM1000 rollout was freaky. I talked to Netgear at the highest level on that one. The listing VANISHED from amazon. Just gone. The Netgear web site vanished. They later officially responded and put things back and it sorta staggered into stock.

I think it was just big demand from ISPs ordering huge numbers and cleaning out stocks.

What amazon says is most likely what happened. "out of stock"..

Ive got a few more charts... They are just all really clean. Im posting to be complete..

12 hours of plot - at 10 times a second. TCP.

Just activated mine.
No, blue lights. all are green.

Standard Specification Compliant: DOCSIS 3.1
Hardware Version: 4
Software Version: D31CM-PEREGRINE-1.0.0.2-GA-01-NOSH

300/20 service.
24 channels down and 4 up.

Interesting... what ISP? Someone on Comcast posted earlier in this topic that they had D31CM-PEREGRINE-1.0.1.0-GA-01-NOSH.

Most likely he's on Time Warner/Charter there.

Cox is also still on the initial 1.0.0.2 release:

From: »Re: Arris SB8200, Cox certified

I'm on Comcast, in Colorado, and I have this firmware. Also, I have one blue light on the downstream. 24/4 locked as well.

im on 1.0.0.2 on Cox in phx. We are 32x4 no OFDM in Phx so all green.

Anybody having luck using the second modem port?

I've played around with the second port but it doesn't seem consistent. If I use port one with my router to computer connection everything works fine. All my other configurations seen to have issues.

seems to work fine, moved my router from one port to the other

I have not been able to get the second port to work. I have not tried that hard tho because no ISP's are supporting multi-ip for residential. I have a thread on that.. All anyone mostly does on that thread is tell me im wrong and that im stupid for wanting a second IP. »No Multi IP for Residential Cox users

EVENTUALLY once we get speeds above 1Gbs then they can do link aggregation using both ports to deliver 2Gbps if you have a router that supports that. I do and my router can do the speeds so im looking forward to that. Its hardware capable of that, but, I think the ISP has to enable it.

I think ISP's need to dust off multi-ip and offer it for a price. They you can have 2 home networks on separate external dynamic IP's.

The interesting questions ive been thinking is if those ports could be firmware enable to do 2.5Gbps each, cuz then with port aggregation you could reach the 5Gbps on the front of the box.

Videomatic3, what ISP are you on ? Can you hook up 2 routers and have them both work ?

How would you get 2.5 Gbps out of a GigE port?

I'm surprised there are issues as Arris seemed to imply that at least for the moment the modem is supposed to effectively work as a three port switch - cable modem LAN and the two onboard GigE ports.

Maybe the hardware can support this and be added or switched on later. »en.wikipedia.org/wiki/2. ··· 5GBASE-T

With a switch you need IP's. You only get 1 dynamic IP with residential service. So only one device will work. You need multi-ip from the ISP to plug in 2 things at once. See my thread I posted on this.

Maybe this'll be implemented on business customers.

What's your definition of working, I can plug another computer and manually set the IP address to 192.168.100.x and view the modem configuration page sure, I can setup my router to have a lan port on the wan port and route the computer to the router first and get internet if I felt like it, but I prefer to just be on the lan port on my router, I haven't tried to team then together yet though
