airport and sleep problem

[glasshorns]

I'm having a strange problemm with my iBook g4 since installing tiger. i can connect automatically to my wireless network and use the internet, etc.

there is some strange goings on when i close the lid.
if i'm just running on battery, the ibook goes to sleep just fine, and the pulsing light on the front comes on. when i open the lid, everything wakes from sleep just fine and airport connects to my network.

BUT, if i have my iBook plugged into the power adapter, and close the lid, the pulsing light comes on for a second, then goes off and the hard drive sounds like it's starting back up.
if i open the lid, everything seems to be working fine, except that my airport reception inthe menu bar shows no signal. it stays this way forever, and when i try to mouse over the menubar icon i get a spinning beachball.

the only way to remedy this is to do a restart and everything works fine.

any ideas?

This is from MacFixIt;

No auto-reconnect after sleep, solutioins Deleting, then re-establishing keychain sets can resolve a number of networking issues in Mac OS X 10.4 (Tiger).

MacFixIt reader Tom Morris reports that deleting the AirPort keychain entry can resolve previously reported issues where Mac OS X 10.4 will not automatically re-connect to AirPort networks after waking from sleep.

Tom writes:

"After installing Tiger I experienced the same reconnect issue in AirPort where it won't reconnect after waking from sleep. The fix for me was to delete the airport keychain entry in the keychain application. After that all is back to normal."

Meanwhile, David Hawley reports that in his case, simply re-entering the AirPort network password solves the issue.

David writes:

"I had this problem. After installing Tiger it would not automatically connect to the airport network on startup or after sleep. I went to System Preferences>Network>Airport>Configure and re-entered the password. It works fine now."

Users experiencing this problem with an AirPort Base station may also want to try resetting the unit.

=========================================

I just spoke to Apple support about this issue. Apparently it is still a known bug not fixed yet, but assured they are working on it. I did find a fix that seems to be working which was to establish a "NEW" location, setting the Join by default option to Preferred Network, removing the exisiting list and re-joining manually via the airport icon in the menu. THis seems to have worked and I am rejoined to the network after waking from sleep.

One user at Apple Discussions forum, reported that changing the channel of the base station solved this issue...
