Hi,
My Network is this, first floor wireless access point with 4 port router. Cable modem internet connected to router, 1 pc hard wired to router. 2nd floor 1 pc with 2 nics and wireless nic connecting to the access point on first floor with wireless nic card and connecting to hub on second floor with one of its two nics. 2 other pcs connecting to hub on the second floor and that second hub connected to the first pc on 2nd floor. Customer said that the three computers on the second floor were able to communicate through the hub before I set up the wireless. I was not informed while on site about this setup. the obvious would be to move hub and internet connection from first floor and connect all three to it and access wireless from first floor. It would involve moving cable connection.
Bottom line is what do I need to do to get the 2 pcs on the second floor connected to the hub on the 2nd floor to communicate with the 3rd pc on the second floor with 2 nics and connected to the hub on the 2nd floor using one of its nics and the other nic is connected to the wireless access point on the first floor.
Thanks
