I'm currently at my fiancé's parents house where they have a Wireless-N WRT-300N Linksys router. The router is set to mixed mode with latest firmware, and when I went to connect my macbook to it...it connected right away but I couldn't get any internet from the connection. I tried disabling airport and re-enabling it, but that didn't work. When I looked at the settings for the airport, it said something like it couldn't get an ip address. I rebooted OSX-Leopard (by the way)...and after a reboot, it connected to the internet right away no problem. Well I thought my problems were over, then later after I closed the lid and put it to sleep for a while and then reopened it I had the same problem. I had to reboot the system again to get access to the wireless. What could be the issue here? Anyone with a clue?
