So when I restart my computer, my internet works flawlessly. However, if I sleep my Macbook, when I wake it up, it is still connected to my home network with a very strong signal, but the internet won't work unless I restart the computer. I have a first generation Macbook from 2006 running 10.4.11. Any suggestions or similar experiences? Is there a way to reboot the Airport card without restarting my computer? Turning it on and off via the icon doesn't work.
