Thanks for all the answers, I honestly didn't think I would get an answer so quickly, I should have stayed up a bit more.
I am trying to set it up just for myself for the time being, at least until I am sure that there are no problems with the new connection.
We have dual channel T1 and voice running over it as our primary connection. It is running from ISP managed CISCO box to our internal Linksys router, from there it is distributed via switches to about 20 work stations and various network connected devices.
Daily operations, I am connected directly to router (bypassing switches) via Ethernet (i don't use wifi in the office unless I need to).
Also the only two devices I need to access to, our Canon imagerunner 2870 is on 192.168.1.240 and our HP 4015n is on 192.168.1.245
They are all on same subnet, same DNS.
Current equipment (but only T1 is utilized by everyone)
a) T1 - Cisco Router - Linksys Router - Switches - Devices Assigned IP/Workstation DHCP - 192.168.1.X
b) Time Warner Cable Router - DHCP - 192.168.0.X
I will connect to both at the same time and report back. So for now it will actually be opposite (wifi for printing via local router and LAN for internet direct to TWC equipment)
