Xfinity boosted my speed to 1.2gb, can I achieve that?

[GhillieK9]

Hello,

Xfinity just told me that my 1gb speed just got upgraded to 1.2. I have the XR700 router and the CM1100 modem. I see that my modem supports the WAN aggregation (hooking up the two ethernet cables to achieve higher than 1gb speed). Is there a way to set my XR700 router to handle that speed? I see it has that ethernet link aggregation but I don't think that is for WAN...right? I think that is just for LAN stuff, for example a NAS or something. What about that 10g port...any way to aggregate the 10g port with the one WAN? 

Thanks in advance!

I don't see that the xr700 supports wan link aggregation but it does have the 10g port that can be used for wan. 

But the CM1100 only has gigabit ports. It uses wan link aggregation for >1gig speeds. 

So you can get faster spees that 1 gig with the xr700 but not with how the cm1100 connects to it.

The WAN port will handle these speeds just fine, the only limitation will be the LAN ports wihch are Gigabit. However, wireless devices will be able to take advantages of your new speeds!

Oh that's good to know! Thanks! I thought even the WAN was only up to 1.0.... Does the same apply to the modem's WAN?

My apologies, I've just doublechecked the specification and the WAN port is also Gigabit I'm afraid! Do you need more than 1000mbps or were you just interested in seeing if your network could utilise these speeds?

[GhillieK9]

Okay thank you! I'll look into a different modem. Thank you all

[plemans]

Keep in mind the xr700's 10g port is a sfp port. Its not a standard ethernet connection so would need a sfp connector/adapter. 

They're not exactly cheap.

[GhillieK9]

Do you know much about the Motorola MB8611 DOCSIS 3.1? It has a 2.5gb port so looks like that would work for me...

[plemans]

don't know much about that device. 

but again, look at the adapter needed to be able to connect the mb8611 to the sft port (amx765 adapter). 

the netgear version costs around $300 (from netgear). 

that's more than the cost of something like the RAX78 which support wan port aggregation and is a triband AX router.

Plus you have the cost of the mb8611.

Your costs are ballooning. Is it really worth the expense for the extra 0.2gig you'll get from your speed? 

Especially when most devices/services can't even saturate gig speeds. 

For example, streaming 4k tv only usually takes 30-40mbps max. 

so you might see the benefit downoading a game (if the game servers are fast enough) or downloading massive files. 

I've got the 1.2gig service from xfinity and the equipment to support it. But I haven't noticed a slight difference from 1gig to 1.2gig. 

and I use a ton of data a month.

Also, I'll be honest, I haven't had to deal with sfp ports so not sure the best option of being able to connect to the sfp port on the xr700 to a modem. 

But the buy in for utilizing that extra 0.2 is quite a bit for your setup. 

[GhillieK9]

$300? Oh forget that...that's not worth it for 0.2

I thought they were like $50?

Is this the right thing...

[plemans]

Unsure as what would be compatible with that router/sfp port. $50 *might* be worth it. 

maybe @Netduma-Liam can chime in? 

that modem you linked to is around $170 plus add in the sfp port adapters even if its only $50, still pushes the buy in pretty high for little extra you get. Again, cost/benefit is a gray zone at those points.
