I have a Linksys WRT54GS running Sveasoft's firmware. I had been using a 17" Powerbook G4 successfully forever with it. Out of nowhere, I started experiencing the problems you describe. I was thinking that perhaps it was the result of an update to Tiger.<BR/><BR/>Then I got the MBP and I have the same issue!! It seems to be connected to the channel that the router is currently on. Whenever the problem occurred, the router's wireless status page would show it was on channel 1. It was set to automatically select a channel. I set it to channel 11 and the problem disappeared for a few weeks.<BR/><BR/>Then, it reoccurred. So, I've now got it set on channel 12.<BR/><BR/>I'm also going to implement the steps that you've described. Hopefully this will lick the problem entirely.

I haven't tried restarting, but I've had to create my home network like 6 time since I got this Mac ( a month ago). Does Apple take computers back if you just don't like it? I'm beginnging to get really frustraited with Mac...it's not overheating- it's random when I have email and Firefox open. One second I'm online and the next the whole connection is gone, missing, disappeared from Airport. Soooo annoying. I’m having the same problem- randomaly my network just diappears from Airport.

This last time they took it in and completely wiped out the hard drive in an attempt to get it to stop typing backwards, the cursor from disappearing, and random rolling of the drop down menus. Well NOW I cannot connect to my linksys wifi which I always was able to do, and I can't even connect using an ethernet cable either WTF????? I HATE HATE HATE this Mac....plus when I call Apple Care, they are closed! My DELL support at least is 24/7!!! So $3200, and 4 attempted fixes later, I am VERY unhappy!!!

1) connected to the wrt300n, put mbpro to sleep
wake mbpro, no connectivity despite airport icon showing full strength, check network prefs, says it’s connected. open a terminal window to ping the router, host is down messages.

2) turn airport off, then on. comes back up in one of three scenarios

Basically it was running "Mixed Mode" which for this wifi router means B, G and N support. I used to connect at a max speed of 130 mbps (I could see this by holding down the option key when clicking on the airport icon on the menu bar). 2 things unfortunately cause issues: 1) there's no way to support just 80211"g" and "n" with this router. it's either mixed b g n, n only, g only, b g only or nothing. i got rid of all my b devices a while ago but like many of you have several g devices. 2) like others I've read about i switched from "Mixed Mode" to "G Only" and the Leopard MBpro wifi wake-up problem is now gone. unfortunately I also lost my "n" so that's no good Anyway I took the plunge and picked up a new airport extreme with the gigE hub and USB. after messing around I settled on having it serve wifi as pure N only. the speed info on the laptop now shows 300mbps within 10 meters or so, 20-54 mbps at the other end of the house. So I definitely got a speed bump, and I can still connect via the G only access point too so now I'm set. expensive though. At least in my case it's clear that a mixed mode config causes problems. Hope this helps someone out there. So in case anyone’s curious, I narrowed the problem down to config of the WRT300n.

I tweaked the settings on my Linksys WAP to G only as well as changed the channel to one that was unused nearby and thought that that had solved my issue, but in the last few days it has started happening again. I realized I hadn't upgraded the firmware on the WAP so I did that today. So far, life seems to be good. Had an awful time with this immediately post Leopard upgrade.

The WRT300N is a 'pre 802.11n' router. what I suspect is going on is that the new OS X drivers are fully 802.11n compliant but the router isn't. Linksys has not released new firmware for the WRT3ooN since early last year. I gave up on using 802.11n with this router, bought an airport extreme 1G and run the linksys in G only mode, the apextreme in Nonly wideband. I now get 300mbps link speed *short distance though). Note the airport extreme has it's own problems though - Back to My Mac issues. People are expecting a firmware upgrade for it soon. good luck..

I had a very similar problem when I moved house. My network setup was exactly the same as the previous house where AirPort connection had been rock solid. At the new house I could barely even connect and the connection would go up and down constantly. Even when it was connected it was clearly so poor that I couldn't connect to anything. I tried most of the things listed above testing each time but the one thing that fixed it was changing the channel number, simple as that (and if I'd done it first it would have saved a lot of time). I think I changed it from 11 to 8 and then everything worked perfectly as before. As to why I don't know. I hardly ever pick up other peoples access points, though I suppose that if there were a lot that didn't display their SSID on channel 11 then I might not know. As to what number to change to, I don't know if I just got lucky the first time, but I didn't try any more (too happy to have it all working again). I'd just add that my AirPort is now under the stairs next to all the incoming power lines and an alarm box with a very noisy transformer, yet it works perfectly, so it's clearly quite robust against electrical noise and brick walls! Just thought I should share my experience.

At the new house I could barely even connect and the connection would go up and down constantly.
Even when it was connected it was clearly so poor that I couldn’t connect to anything.
I tried most of the things listed above testing each time but the one thing that fixed it was changing the channel number, simple as that (and if I’d done it first it would have saved a lot of time).
I think I changed it from 11 to 8 and then everything worked perfectly as before.
As to why I don’t know. I hardly ever pick up other peoples access points, though I suppose that if there were a lot that didn’t display their SSID on channel 11 then I might not know.
As to what number to change to, I don’t know if I just got lucky the first time, but I didn’t try any more (too happy to have it all working again).

I’d just add that my AirPort is now under the stairs next to all the incoming power lines and an alarm box with a very noisy transformer, yet it works perfectly, so it’s clearly quite robust against electrical noise and brick walls!

The web is full of dead end solutions for the infamous Airport on but no internet on my MB. My problem is similar to others : PWBG4 all fine, MB(2ghz Core2Duo) no internet with an old Airport EXtreme. But not all networks, only some, and only the preferred. Apple has no solution, yet it seems that after too many writes and (it seems) 10.5.4 upgrade the system preferences get corrupted. From the link Brad posted I found a solution. Now, trashing the preferences and a restart did the trick, yet it seems that after a while the prefs get corrupted again, especially if you roam a lot and the prefs are re written all the time. REpeat steps :-( At least it fixes it temporarily and it is the most effective solution I found to date. Cheers J. Folks,

I called Apple Support and had the perfect experience for my first time calling them. Here's what they did and best of all, IT WORKED!! 1. Power down your Mac. 2. Take out the battery. 3. Hold the power button down for 15 seconds. 4. Put the battery back in. 5. Power on your Mac. That's was it!! Airport was on and working like normal. If you are still having issues after this, I suggest sending in your Mac for repairs or to let them, at least, look at it. I hope this help you all. Good luck!!

SOLUTION: Re-install operating system disk and archive. Airport works fine once again. Have had major connectivity issues with airport ever since I updated to 10.5.7.

Couldn't actually use the WLAN with any other device either after the MBP woke up. My router only supports B and G modes, and was using mixed whilst the problem was occurring. ATM it seems changing the WLAN mode to B fixed the issue, atleast I am able to sleep-wake my computer and regain the connection succesfully.
