OK, so here is my situation.  I have a basic setup using the ER605, OC200, a new switch coming in this week SG2008P (currently using SG1008P), I have one EAP245 and one EAP670, I actually just upgraded one of my EAP245 to the EAP670 and will likely install my unused EAP245 to my garage.  The EAPs are wired using CAT8 cable (I know it's overkill but I wanted to be safe for the future).  So that being said I have Gigabyte Fibe Internet at home and just found out I have access to 3 GBS Fibe for like $20 more a month (no brainer).  I want to do it but will I be able to distribute that much bandwidth with my current hardware?  I don't think so as the VPN/Router only has Gigabyte ports and I do not see a 2.5GB VPN/router offered by TP.  The EAP670has a 2.5GB port but if I am bottlenecked at the Router, what's the point?  I know there are 2.5GB switches available and right now it almost seem as though using the Router (ER605) will be my main issue.  

I could get rid of it and simply do everything via a switch but loose the security of the ER605.  

Looking for thoughts on this and if anyone else has a similar setup and they could explain their hardware used.

Thank you,
