Im confused, you are just replacing one for the other right? I could not find specs for the Linksys you listed so from this point on I am going to assume it was a router as well.. Anyway your network should go:
NetGear MR814v2 ----> HUB ---> to devices (CPUS)
The Linksys should be removed, you should never have 2 routers before your hub, it gets confusing and you could end up with IP Loops (doubtful with home Cable/DSL routers, but still). Also, If you are trying to create a DMZ then it should look like this...
MR814v2 ----> to a Firewall device or PC with 2 NICs 1 in 1 out ---> HUB ----------> devices (CPUS)
I hope this helps, if not, and you are dead set what is the reason behind keeping the other router? If this helps please add to my Rep, thanks!
