Recommendation to optimize network?

[Kartajan]

Current setup:
Cable Modem-->DIR655-->24 port GBE Switch
** Wireless is DIR-655---> n clients; Vonage Box-->G Clients

Just got a new Cable Modem from TWC; ARRIS DOCSIS 3.0 Touchstone Residential Gateway DG1670A. They are telling me my speed will be going up from 35/5 to 200/20.

I am thinking that my DIR-655 may be a limiting factor, so I want to remove bottlenecks. Should I replace the DIR-655 with something along the lines of the ASUS RT-AC68U? Also, I kept n and g wireless separate to minimize potential bottlenecks- good idea or bad?

I'd separate on band as well to get maximum performance. 802.11n on 5ghz and 802.11g on 2.4ghz

I ran across a stupid cheap AC750 wireless at FloorMart, and figured I would try it out since it was on sale for $30.. I actually got better speeds on my n clients despite the thing being only 10/100 ports for connections...


Note that I am currently hooked in as follows:
Cable Modem--DIR655 <Plan to replace w/ RT-AC68U>
DIR-655 is DCHP w/ wireless g turned off,
---vonage box with G wireless
---GBE Switch (unmanaged)-->all wired (GBE & 10/100)
Plan to replicate on AC68U what is now on DIR-655 only adding ac to the mix. Any issues you see in respect to things like ipv6, any other gotchas for network guessers like me??

ADL INFO from NDT:
The theoretical network limit is 176.40 Mbps
The NDT server has a 345.27 KByte buffer which limits the throughput to 85.44 Mbps
Your PC/Workstation has a 255.21 KByte buffer which limits the throughput to 31.58 Mbps <----------- I am ASSUMING this is the DIR-655 limiting throughput
The network based flow control limits the throughput to 32.28 Mbps<------- I am assuming this is the ISP limiting throughput until the new OMFG speed plan kicks in

FYI... I got the RT-AC68R and dropped it into place. I am unschooled as to ipv6, so I am not sure what I need to in that respect. Otherwise on an IPv4 end, all looks good. My network speeds on 5G "n" are respectable, as well as 5G AC. I did, however, have to put my vonage box on DMZ in order to make an outgoing call. I am also going to have to look into potential issues with my win8.1 box talking to my NAS, but at least I appear to be ready for the crazy speed when it get turned on (Allegedly from 1-10 April it should turn on... Hoping 1 april is not a joke.....)


PS: the Floormart AC box has already been removed and sent to a better place... I would not have that "thang" disgrace my network for extended periods of time....

I have found that as configured, IPv4 works as intended, to include desired separation of networks.

The only odd thing is that IPv6 is not cooperating within the same confines. For some reason, IPv6 does not want to push down addressing in the same manner as IPv4. With the TWC provided router, it does not want to push addressing down to my subordinate router.

Can anybody tell me if this is (a) by design, or (b) a probable misconfiguration of either the top router or bottom router?
setup is as follows:
Arris DG1670A--RT-AC68U
Arris DG1670A-----vonage box with G wireless

RT-AC68U---GBE Switch (unmanaged)-->all wired (GBE & 10/100)
