So, Like most of us, I close the lid of my macbook pro sometimes and when I do it goes to sleep for lack of a better description. Sometimes, in fact, alot of the time, when I open the lid of my macbook at home or at work the wifi seems to not come back right. I ill be joined to a wifi network, everything is fine, I have an IP I can surf the net, etc. I close the lid and it goes to sleep. I open the lid it asks for my password and I give it, everything comes back fine, and I am connected to the target network however I cannot surf the net. If I check my network properties it shows my ArPort connected to the SSID with a self-assigned IP address. If I ask it to renew the DHCP lease it still gives its own IP. Sometimes if I turn the card off and back on, it fixes it, but usually I have to reboot my mac to get rid of the problem. This happens on more than just my personal home network, however both networks (work and home) use linksys wireles N technology. Is this a problem you have heard of or experience? What should my troubleshooting steps be? I would like to avoid AppleCare because I hate the idea of not having my laptop for a few days while they "determine there is nothing wrong" at the local store.
