I have several odd networking problem with my Snow Leopard Mac and am hoping someone can help. My Mac has trouble switching between the wired and wireless connections. If the wireless (Airport) is enabled and I'm also plugged in via the wired ethernet connection, access to the Internet is very slow. If I turn off airport, everything speeds up. It would seem like the machine ought to know which is the faster connection and just use that but it doesn't. What happens is that I end up manually disabling the Airport whenever I plug in to the network directly. My other problem is that when I unplug from the network, the Mac doesn't seem to realize it. Even if I turn Airport back on, it still continues to try to use the disconnected wired connection so I lose access to the Internet. I have to go into networking preferences and disable the ethernet interface before it will realize it should use the wireless connection. It seems to be like this should be a bit more automatic. It is getting really irritating. Any ideas? I have Snow Leopard 10.6.2.
