Thanx to everybody 4 ur suggestions. the amazing charts conference was great and I learnt a lot and got opportunity to provide the feedback and problems.
I have hard wired all the rooms.but still since we including my nurses are using the laptops i will keep the wired connection as a back up .I am also thinking of doing N networking as somebody mentioned in the conference.i am looking in to the adapters and routers also.if all that does not work i will look into servers.
i got mixed views from people about server.
i will update u as i go along.
i want to give special thanx to Bert,Adam,jim,Brian,Fred for their time and addressing the issues.
good luck Bert for the updates.
