Slow connection to network

I have noticed that when I turn on my Acer Aspire 5315, it takes a really long time for the connection to my wireless network to connect. Once it goes though, everything is fine. I have no slowness then. It only happens when I 1st turn on the laptop. When it does, my anti virus loading screen pops up, then I can't click on the network icon in the system tray. I have managed my connections and removed all of the connections I never use so now I only have 2 listed.

Also, while it is trying to connect I can't pull up my network connection sharing folder for windows vista home basic. This isn't the worst thing that has happened to me but is quickly becoming one of the most annoying. Any help/suggestions would be appreciated. Thanks.
