Do I need to change channels manually you think? I've read and read on this, but still get lost in some of the technical language. It barely shows any bars for signal strength. Past several days it keeps going in and out. one channel is 11 and the other 149, which I believe both are defaults. WHat shall I try to change them to? Is there a way to see how fast the wifi is actually running? I hold option down and click on the airport icon on the top toolbar, but I don't know what all the info means Thanks for any help.
