Can someone help me..
I used a straight cable to all my wiring,

Straight cables. Crossover has not been needed for quite a while.

Straight cables.

Crossover cables would only be used from one machine via it`s Ethernet port to another machines Ethernet port.
Because you have routers, and switches in the Network no crossovers are needed.
