Local Network. Unable to connect

[CHinHairs]

I run a tekkit server on my main PC and I am able to connect to it from that PC, everyone is able to connect to my server. Nothing wrong right? Well I try to connect to the server from my laptop which is connected to the same wireless router and I am unable to do so, help would be appreciated

EDIT:

When attempting to connect to Tekkit from PC 2 I dont see it as an active server on the server page, but when I choose it I get the logging in message. After about 40 seconds it tells me that I took too long to log in.
