Keynote remote not connecting after iOS 6 update

So before iOS 6 keynote remote connected with almost no problems. Now it's a pain. First, when I create a network using my MacBook Pro (brand new and totally up to date), when I connect to said network using iPad preference the wireless antenna no longer shows, so one cannot be sure if the network has connected.

Second, I open keynote remote on my ipad and try to connect. Yes, I know how to do it so don't tell me how to do it. Sometimes it says it can't connect to a network. Other times it says that I have to unlink keynote when no link has been made. Other times all will go we'll until I enter the code, a step I still do not comprehend, but when I enter the code it works and works and works but never connects. Other times it will say the connection cannot be made.

I have had to completely shut down my I pad and restart my iPad. I am doing all this while my class is waiting because the iPad still does not multitask. If I have keynote remote running with the presentation, I cannot go to numbers to take role. Also once I tell the iPad to run the presentation, I don't think I can do anything on my computer. That though has been a problem all along.

Can anyone help resolve these issues?
