Second IP needed - ARRIS - SURFboard S33 with Comcast 1200Mbps Service

@KAIREWA  Thanks a lot for your reply, 

I attempted setting up Link Aggregation on my Orbi Router which as a feature for that, then I also tried looking up on the modem configuration, but I couldn't find anything related to link aggregation in the modem settings themselves.

I'm really frustrated with this. Sure, I'll post here if I find a solution.

@KAIREWA One question, do you get above 1000Mbps when you have both ports on your modem working? I would love to keep this modem if Comcast would drop in and help with the two IPs setup, because it is an excellent modem, but then again, if they don't maybe I can try the modem you mention as it also seems pretty good.

I read that for link aggregation to work on that SB8200 modem, you must have a router which supports it. (Mine does).

Thanks.

@RealAct realistically for SB8200, each port pushes 940-ish Mb. Having LAG enabled will allow to push over 2.5Gb from the router but I suppose Comcast restricts dual IP for LAG.

@KAIREWA Thanks! 

What kind of router do  you have? So you enabled LAG in the modem only, or both the modem and your router? My router has LAG, but it only has 1GB ports, I could only get something above 1000Mbps if I connect wirelessly to it. Which is what I'm trying to avoid, Whence I need to find a way to enable the second LAN port on the modem.

@jlavaseur Hi,

How exactly do you have dual WAN setup? Do you use a router or connect your rig directly to your dual LAN modem? 

I can only get one LAN  port on my modem to work at a time, when I restart the modem whichever gets the connection first that's the one that works, the other port is dead. I can ONLY use one LAN port in the modem at any given time. The manufacturer says I need an additional IP from Comcast for both ports to work.

Thanks.

@jlavaseur thanks for your reply, 

I wish I knew more about networking, then maybe I could do something like that, but I really have no clue how to set up what you describe.  Where do you configure the dual WAN? Is it on the router settings? Or in the computer?  Also, after setting up dual WAN you connect your PC normally to one of the router's LAN ports? 

I see your router has a 2.5 LAN port, mine doesn't, I can only get 1200 speeds Wirelessly from it. It can receive 2.5, but its LANs are only 1GB.

Maybe then cannot have your same setup. That's why I'm trying to make the second port on the router work, so my main desktop can connect directly via ethernet to the modem and get the 1200Mbps from it.

@jlavaseur thanks,

I just hope one of the Comcast employees that look at these boards reply to me and offer some help.

@ComcastEva  @ComcastAaron @ComcastMorgan  or any other employee could you please help? How do I get a second IP so both ports on my supported and suggested modem work?

Thanks. 

@RealAct

They are phasing it out but I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. We've seen cases here where they have been able to get this accomplished for customers even when it is not listed in their rate cards, YMMV. You should get a reply here in your topic. Good luck ! 

Thank you @EG for bringing more visibility to this topic and @RealAct we would be happy to further assist with this.

@EG thanks so much for doing this, I really appreciate it and the information.

@ComcastEva Thanks for responding, i have already done so. I have contacted you guys via the chat.

I appreciate your help 

@EG Unfortunately I have bad news,

So far, although the Rep who is helping me has been extremely polite and knowledgeable/willing to help etc,  they haven't offered anything other than suggesting for me to change to a business account type of service which is WAY above my budget for internet and offers way less internet speed for even higher prices.

After doing my own research I found out that their XB7 Gateway has an additional 2.5GB port which perhaps I could use (Turning my Orbi into an Access Point Only and their Gateway doing the routing type of scenario) but of course that would cost me more monthly, and I'm not even sure if I have to pay for the XB7 Gateway. 

I also need to research and see if my Netgear Orbi router would work well like that. I have to research more. Honestly I'm starting to think I should move to AT&T Fiber which is also available for me and has 1GB Down 1GB up for $70 a month, lower that I pay now for Comcast.  I'm not getting anything above 1GB with Comcast anyway due to their silly restrictions.

So I'm now asking more questions about that option with the XB7, I'll post more at a later time.

Why in the world would Comcast stop offering second IPs now with the arrival of Wi-Fi 6 when more and more modems and routers will be available with 2.5 ports is beyond me. Frustrating to say the least.

@RealAct  if they do provide you with an additional IP address, you would need to enable LAG on modem then hardwire each WAN out to an enabled LAG router.

FYI dual WAN and LAG may not work to output 2.5Gb as the bootfile may not allow that to happen which is why I say I’m left with 1IP when I switch on LAG on my modem.

You’ll need another modem connection with a separate account to utilize LAG functionality for 2.5Gb connectivity. Or upgrade speed to 2Gbps

Hello, @RealAct. 

While I'm glad you were able to find a workaround for your situation, I'm sad to hear you are still unhappy with the outcome. 

We definitely do not want to you feel like you are being forced into using our equipment due to 3rd party equipment limitations. 

We want to make sure your services are able to meet your usage needs while having options when it comes to how those needs are met. 

While using your personal setup with the Surfboard, were you finding that setup wasn't meeting your usage needs? While I understand using a Gigabit connection when you are paying for 1.2GB isn't ideal, it should be more than enough of a connection for most activities. 

Please let us know if you were or are finding that your service is lacking in some way as it could be an indicator of more underlying issues that we can take a look into for you. :)

@ComcastTambrey  Sorry, but the limitation is not because of 3rd party equipment, the limitation lies within the Comcast configuration for its internet services for home costumers itself where you limit the use of dual port modems by not allowing a second IP to be used with a supported modem, and force users into having to use your own modem if they want to take full advantage of the connection they pay for, like in my case. 

I do have the right equipment, I have a supported modem and a device with a 10GB Ethernet port. But you prevent my supported modem from working the way it should work by limiting it and refusing to provision it with a second IP, which it needs to properly function.

Regards.

Sorry for breaking the forum rules. (I didn't know the use of bold or upper case in some phrases of a paragraph was not allowed, my apologies)

@RealAct, Our configuration does not limit the customer's ability to use multiple ethernet ports, hence why you are able to switches as well as both ports on the equipment we lease. 

Unfortunately, we cannot guarantee the functionality of 3rd party equipment and we cannot change the requirements that 3rd party equipment has for enabling each port on their devices. 

We understand that it can be frustrating that we are no longer offering multi-ip for residential customers, and apologize for the inconvenience it may cause. If you change your mind about any of the alternative solutions such as transitioning to a business class account for that particular feature, we are here 24/7 to help with any of those changes. :)

Actually, Xfinity is limiting service and equipment function by limiting the amount of IP addresses we can use on third party modems. I have a T25 Arris surfboard. I have a home network with 3 computers, two tablets, two cell phones, and like 3 gaming consoles. You allow one internet port with a single IP address on my modem with my entire network running through that single port when I could split the bandwidth and have two IPs utilizing one for online gaming and one for the rest of my home network if Xfinity wasn’t limiting me to a single IP address. Arris designed these modems with two internet ports for a reason, and Xfinity’s service does not allow us to use both ports.

If you want to monopolize this industry, at least give us the best services you can provide. Stop being stingy and let us use our equipment to it’s fullest potential. All it takes is giving us the ability to authorize splitting our connection into two IP addresses so we can directly connect a second network or device…

You're not strictly limited; you can move over to business class.
