Since upgrading to 10.4.11, I have been losing my ability to communicate
with my wireless router. The signal is strong. I just can't talk to
it. I can't even access the router's control panel.

I have tried turning Airport off and back on but that doesn't fix it.
The only cure I have found so far is to restart the computer, which
takes time and forces me to stop working on anything else. Is there a
way to restart airport short of restarting the computer? Even a simple
C program or shell script would help.

I have filed a bug report with Apple. A related issue is that anacron
seems to run every job twice. This also started with 10.4.11.

I would go back to 10.4.10, if I could but that isn't an option right
now. I would have to re-install the OS, and there is no guarantee that
would actually solve the problem.

Try changing airport channels. You might be in a situation where a
neighbor's wi-fi router is operating on the same channel as your router.
Also, make sure there are no 2ghz cordless phones in use in your home
while you are using your wi-fi connection.

I have tried channels 1 & 6 with the same results. I will try another.

We have had a cordless phone for several years. It does not bother the
PowerBook, which sits right next to the base station. The MacBook Pro
has only started to act up since I installed 10.4.11.

I did a little research and found that the 2007-004 Airport update
caused some people problems exactly the same as mine. I installed this
at the same time as 10.4.11, which may be the real problem.

I saw on Versiontracker that somebody found that clicking on the Airport
icon would restore connectivity. I tried that and it worked once. It
remains to be seen if it will work all the time.
