Currently Being ModeratedSep 24, 2008 2:43 AM (in response to dexdubious)I have a very similar situation.
When I power my recently bought iMac 24" 2.8 it does not connect to the network. I have to disbale & reenable the airport adaptor like 10 or 12 times for it to conenct. Once connected performance is great and never disconnects.
I own couple of other equipment that conencts without any problem to the network (McBook, PowerBook G4, iPhone 3G, iTouch, Nintendo Wii, AppleTV), so it is not a network problem.
Fun part is when I called Apple's support centre. First we did some tests, creating new location, testing LAN conenction (via cable). After more than an hour, the solution was to reinstall Leopard (!!), as it seemed a configuration issue. Computer is quite new, so I decided to go for it. After reinstallation, WLAN still did not work. I called again Apple Support centre and we did basic tests, again more than an hour on the phone. After all unsuccessful tests, they asked me what OS level I had (fresh installation with nothing installed). The CD version is 10.5.2. The answer I got was "you need to update to 10.5.5, we do not support 10.5.2".
I have to say that I am a happy Apple customer (see all my decives up there) but the support level they provide is not at the level we expect.
I will take my iMac to an Apple Store and hope it gets fixed!iMac 24", PowerBook G4, MacBook, Mac OS X (10.5.5)

Currently Being ModeratedSep 30, 2008 11:25 AM (in response to dexdubious)Bought my iMac in mid-August, running 10.5.4....have had connection issues since day one. I normally have to reconnect once (sometimes twice) after bringing the mac out of sleep. I had read that 10.5.5 was to fix this issue, but from the topics on the board it doesn't seem so.
Apple please fix!iMac 2.8, Powerbook G4, Mac OS X (10.5.4), Airport Express
Currently Being ModeratedSep 30, 2008 1:10 PM (in response to dexdubious)i have the same problem with a linksys wrt54g router. I borrowed a friends airport express, and never had an issue. all other devices on my linksys work fine, but the imac is intermittent. I'm not sure what would be causing the issue with the imac and linksys, but apparently if i was to purchase an airport I think the connection would remain stable, since it did for a week on a friends airport.
Currently Being ModeratedOct 2, 2008 5:52 AM (in response to J.I.)I have a slightly different Problem since 10.5.5.
Neither my AirPort nor my Ethernet-LAN work. Im not able to get an IP (IPv4 only. IPv6 seems to work over my Wireless-Router)
I tried quite a lot, to fix this, but the problem remained. (See this thread for details)
I did a clean install on my 24" 2,8GHz iMac everything worked fine. Then i updated. After the update my iMac had a Kernel Panic and after the reboot i have the same issue again.
It can´t be a hardware-failure, cause i have a Test System on a second partition with 10.5.4 and everything works fine here. And even under Parallels running under my Main System i have network connektivity.
Please Apple FIX THIS SOON.
Lots of people here in our Company are switching to Apple right now. If this is their first Impression......... Say GOODBYE to about 1500 potential customers.

Currently Being ModeratedOct 3, 2008 8:01 AM (in response to dexdubious)As I've stated in other threads about this, this is not a hardware or router issue. This is an Apple software problem. More specifically related to the latest airport update "AirPort Extreme Update 2008-002". My iMac ran perfect for 10 months until I updated the Airport Extreme software (that controls the internal iMac wireless card) back in June. Another easy test to prove is software related, when you have 0 bars, click on the bars...a pop up window will allow you to toggle the airport setting. Just disable airport, and then re-enable it. Four bars again! Toggling the software off and on as a workaround is not a hardware or router issue...it's a bug in the software. I first had this problem back in June running OS 10.4.11. Upgraded the "Airport Extreme Update 2008-002" software, and BAMMM!!!! No/weak wireless signal. I then upgraded to 10.5, and still had the problem, so I upgraded to 10.5.5 and STILL have the problem. Until Apple fixes the "Airport Extreme Update" software, you will see this problem on any version of OS that has Airport Extreme Update 2008-002 on it. The only way to fix this is to revert back with time machine to before June when this "Update" was released. I, unfortuneately, did not have time machine back then (as stated earlier, I was running 10.4.11 back in June). So I must wait it out until Apple fixes this. The problem is not the Mac OS, or any hardware. It is specifically the "Airport Extreme Update 2008-002", and how it interacts with the iMac's airport card that is causing this (since other Macs are not affected by this software bug). Everyone call Applecare to let them know!!!!!iMAC, Mac OS X (10.5.5), Aluminum 2.4 Ghz Intel
Currently Being ModeratedOct 12, 2008 12:41 AM (in response to dexdubious)Well..Well...
I went out and spent the 80 bucks on a new linksys 160N router, and guess what...
Everything works fine...no more connection problems.....
Must be that these new Imacs don't like working with anything old??

Currently Being ModeratedOct 12, 2008 1:56 PM (in response to dexdubious)I've had the same problem since I bought my machine. It has yet to be fixed and the only work around that I've been able to pull off is buying an apple router and running it at 5ghz n. The problem there is that none of the other machines using the router have that capability.iMac 24in Intel Based, Mac OS X (10.5.4)
Currently Being ModeratedOct 13, 2008 11:59 PM (in response to dexdubious)I too have the same problem.
I bought a new router (Linksys) because whenever I would reset the old one (Belkin) it would seem to work. But, the dropped signals *came back* with the new router. My PCs have no problem and I've come across others with the same issue.
Today, I brought a D-Link WL USB adapter. Aside from the fact that none of the boxes from any of the manufacturers say "Mac compatible", I decided to take a chance anyway. Had to download the drivers from D-Link (10.4+) and so far, NO drops.
So, I believe the issue is with the iMac. By the way, this one's only a month old.iMac 20, Mac OS X (10.5.5), 1G iPhone
Currently Being ModeratedOct 14, 2008 12:13 AM (in response to Patrick Haynie)I've the exact same problem with my imac. My wireless router is the Apple TimeCapsule.
Before the TimeCapsule I used a Netgear WNR854T without any problems at all...
My other devices (iPhone, IBM laptops, HTC phones) connects without any problems to the TimeCapsule...

Currently Being ModeratedOct 16, 2008 5:32 PM (in response to dexdubious)Ok guys....I now have irrefutable proof that this is an Apple software issue related to the "Airport Extreme Update 2008-002" software update. I just spent an hour on the phone with Applecare and proved this. He first had me trash my system preferences, reboot, and create a new network connection. I did as he said and my signal still dropped after all that. He thought that maybe I had a bad airport card (hardware issue)....well, to prove him WRONG we did the following:
Get your OS X 10.5 install disc out, and insert it, reboot...hold down the "c" button on the keyboard while it boots. This will boot the computer from the CD instead of the harddrive. Once you get to the "Welcome" page after it's booted up from the CD, you'll see the wireless bars in the top right corner. Click on that to turn airport on, and join your network. Once joined, you'll see a strong wireless signal. Now just let it sit there for several minutes...like 10 minutes. You'll notice that the signal stays strong without dropping. What this proves, is that the computer is now running it's wireless settings from the install disc, not the harddrive. The install disc does not contain that Airport Extreme Update 2008-002 because the disc was made before that update came out. Booya! That's proof that it's not a hardware issue, or router issue. Since other Macs running 10.5.x are not having this issue, that proves that it is not an OS issue either. It is an Airport Extreme Update software issue, and it only affects intel iMacs. I asked the Applecare guy if they are aware of this issue, and he said that they were. I then asked what they plan on doing about this, and he stated that since it is a software issue, all I can do is wait until they release another update that fixes this. He did not know when this would be. So for now, I just have to live with it. My workaround is to toggle the airport off and back on. This will give me some bars for a few more minutes until it drops again. It's a major PAIN, but I have no other choice right now. Hope this at least sheds a little light on the problem to you guys.iMAC, Mac OS X (10.5.5), Aluminum 2.4 Ghz Intel
