Airport not working after sleep?

Message #1 - Posted 2008/04/08 - The Older Gentleman

Intel iMac, OS 10.4.11.

After waking the thing up from sleep, Airport seems to be taking a long time to re-acquire the signal from the wireless point that I've got plugged into the DG814 modem/router.

(Still running a non-wireless enabled old G4 on the system, so just plugged a wireless point into the router a couple of years ago).

Other wireless Macs on the system don't have the problem, so it's an iMac issue, not a modem/router or wirelss point issue.

Tried restarting, turning the router off and on and ditto the wireless point, but no real joy. It always comes up in the end; just takes time.

I suppose I could just plug an ethernat cable in, but does anyone have any ideas what might be the problem?

How long is "long"?

No, but it is worth monitoring the system.log file while the iMac's trying to reconnect.

Cheers,

Chris

Had a similar problem with a PB some time ago and found that the only easy way was to turn Airport off - on the machine in the menu bar - and then turn it back on. Never did find the true cause but since the last update it now works fine.

It used to be the case that if your 'Location' was set to 'Automatic' then some strange networking stuff could happen. Try creating a named Location and see if that sorts it out. If not, no harm done.

Yes, I've done that and oddly, it seems to help.

A couple of minutes? The Airport icon on the top of the screen greys out, then comes back at full strength, then greys out again...

Hm. How does one do that?

I generally try not to faff with things if I don't know what I'm doing, given that I have huge faith in my ability to sod things up. How would one create a named location, for example, and what would one do with it?

'Locations' are ways of having different configurations available from a selection. So, for instance, you could have two locations called 'Work' and 'Home' that would change your network settings between what they need to be at work, and what they need to be at home (IP addresses etc).

When it's set to 'Automatic' (which I think it is by default) then it just guesses which one is right, even if there is only one. Sometimes it doesn't seem to get it all right.

I can't remember how to create new Locations under 10.4, but I'm pretty sure it's in the Network preference area. I _think_ you click the 'Automatic' location, you get the drop-down, and there's an option to create new ones.

I think...

Fire up Applications/Utilites/Console before sleeping. Press "Log List" and choose All Messages.

When you open the machine, watch for anything getting logged that might be to do with the Airport or networking.

All I get is "Kernel Airport: Link up on en1" when the Airport comes up, which it does in a couple of seconds of opening the lid.

I think you think right. At least that's the way it presents itself here in 10.4.11
