Currently Being ModeratedDec 3, 2007 10:46 PM (in response to Aodan)Not really offering any solution, but a possible insight.
I am having a similar problem, and I just may have had an epiphany tonight. Let me pose a question:
Do all of you have cordless phones? If the answer is yes, that might be the problem, because that seems to be mine.
We have 2 wireless iBooks (10.5.1) and another iBook (10.4.11) connected to the D-Link router by Ethernet (remains connected to the internet when the wireless 'Books are not). One of the iBooks is generally used on the second floor of our house, located almost directly above the router. The other is about 50 feet away on the same floor as the router. The one above has not experienced any Airport problems (at least, not after the 10.5.1 update), the other one has lost connectivity repeatedly over the last few weeks.
It was not until tonight, when I had the generally working iBook next to the problem one in the same room that I began to lose my Airport connection . . . +only when the phone rang+, +or an outgoing call was made.+
A call to Roadrunner suggested that the phone signal was interfering with the router, but as it was not their router (installed previously by Verizon) there was nothing he could really do for me, except to offer a little advice, to call D-Link and have them change the channel (I think )
The phones are not new. We have had the same service since May. The only things that have changed is Leopard (or the 10.4.11 update). The conclusion is obvious.iBook G4 1.42 GHz; iBook 500 MHz: iMac G3 350MHz;, Mac OS X (10.5.1), 1GB RAM
Currently Being ModeratedDec 4, 2007 3:11 AM (in response to Susan M)Well it's not obvious that we are all experiencing the same problem. But if you are having wireless phone interference problems that only started with 10.4.11 and 10.5 then I would say that manually adjusting the channel on your router may solve the problem.
Some routers (primarily Apple's) have a channel setting called "Automatic" which is supposed to automatically change to a different channel if interference is detected. Let's hypothesize that in 10.4.11/10.5 the wireless software was changed so that it is now a little too sensitive to poor signals (or maybe it just keeps trying too hard to get a "best" signal). This might be causing "channel chasing" which would present itself as constant scanning.
If that is the cause, then a workaround (until Apple re-adjusts the sensitivity in 10.5.2) would be to change to a manual channel setting. Which channel will be best for your particular environment can only be determined by trial and error.
If you don't have an automatic channel setting on your wireless router (or don't have it set to automatic) then you can still do trial and error adjusting of the channel. It may solve the problem.
I have no bad wireless phones in the house (I specifically bought DECT phones that don't share the same frequency as wireless routers) but I know that my neighbours probably have phones that could be interfering with me. Think of it this way, if you can see 4 or 5 of your neighbours' routers on your airport dropdown you can assume that there are at least that many wireless phones potentially sharing the same "airspace".

Currently Being ModeratedDec 4, 2007 5:11 PM (in response to Aodan)I loaded up Leopard for the first time yesterday on my PowerBook G4 and immediately had the same airport drop out problem. (I use wireless DECT phones for my landline but no calls were being made or received when the wireless was dropping out.) My internet connection is via an Orange/Sagem broadband wireless router (France) and when I first set it up last year I had to interpose an Airport Extreme between the Sagem router and the two macs in use, mainly because that was the only way each computer could ichat with separate third parties at the same time. The Sagem and the Airport Extreme are connected by ethernet cable. The Sagem wireless facility has always been active - it had never interfered with the Airport Extreme under Tiger and I had never bothered switching it off - so after reading the earlier posts on this thread I thought switching off the Sagem's wireless facility might resolve the problem if the signals were conflicting. I did notice that both the Sagem and the Airport Extreme had been operating on the same channel, but I found switching off the Sagem wireless facility did not stop the wireless drop out problem. However I now seem to have a successful (temporary) workaround by plugging in a spare Airport Express near to the PowerBook - it's actually within one metre distance. The Airport Express is amplifying the Airport Extreme signal on the same home network for the PowerBook to pick up wirelessly. The Airport Extreme is only 5 metres from the PowerBook so I'm none the wiser what the original problem is other than to assume that somehow maybe Leopard needs a stronger signal than Tiger, even over such short distances.PowerBook G4 1.67GHz 17", Mac OS X (10.5.1)
Currently Being ModeratedDec 4, 2007 7:28 PM (in response to Aodan)I'm having the same problem. Very frustrating. About every 15 seconds, my MacBook Pro drops its connection and after about 5 seconds, reconnects. This makes working at home very difficult. I hope Apple fixes this soon.
Currently Being ModeratedDec 4, 2007 8:01 PM (in response to bajas21)I've noticed that the airport menu indicates "Scanning" for a few seconds when I first click on it. It then says "On" and stays that way. The more I think about it, perhaps this is intentional, since when you pull down the menu it shows all networks in range that it sees. It would have to scan for other networks occasionally, other wise you wouldn't see them. I don't know if you can get it to show you when it's scanning without pulling down the menu.
Maybe this isn't really a bug, but a feature that's working as advertised, and the problem is elsewhere?15" MBP 2.16 ghz 1gb, Mac Mini, AppleTV, AEB, AX, iPhone 8gig, Mac OS X (10.5.1)

I'm inclined to agree with this statement, every time I click or alt click the airport icon in the menu bar it says scanning for a few seconds and then switches to ON. It however stays that way permanently and I have no other wifi issues with my 20" iMac on my D-Link DSL-G604T wireless router.
I don't know if this is in anyway connected, but I had to re-install my Tiger system back onto my G4tiPB because the wifi signal wouldn't get higher then 75% and the speeds were appalling, whilst in Tiger it works just fine. I haven't had any problems downloading updates or software, I will try some HALO online and see if I can manage that, although knowing my luck it won't be leopard compatible!iMac Intel 20" & Titanium G4 Powerbook, Mac OS X (10.5.1), Tiger on the Ti Book, Leo on the iMac!

Currently Being ModeratedDec 4, 2007 9:03 PM (in response to dawnrazor)Well, even when I don't click on the airport icon and I don't see the words "scanning" it still acts up 98% of the time and I can't get online... Any other ideas??MacBook, Mac OS X (10.5.1), White C2D 160 Gig HD (Late 2006)
Currently Being ModeratedDec 4, 2007 9:42 PM (in response to briboli)Sounds like you have exhausted a lot of the obvious tricks, however when I loaded Leopard onto my machines I had a ton of problems getting hooked up wirelessly. Since it had been working faultlessly in Tiger a few hours previous I immediately blamed leopard, it being the only thing that had changed.
HOWEVER, and I would recommend this to everyone installing Leopard and using wifi at home. Reboot or restart or reset your wireless router, I don't know why it needs it, presumably something to do with the new OS or something anyway, it worked for me, I hooked up the router online, restarted the access point twice I think and up it came and has been working perfectly since. I'm in a urban centre with a lot of networks around me and I'm not having any issues so far, although I'd swear that the connection is slower since Leo, but that could just be me.iMac Intel 20" & Titanium G4 Powerbook, Mac OS X (10.5.1)
Currently Being ModeratedDec 4, 2007 10:47 PM (in response to dawnrazor)I have an Airport Extreme (which I've reset to default settings) and I still have the problem. I've reset it for other reasons and that didn't impact the situation.
One thing that would be nice to see y'all try is to use a utility like Cocktail or OnyX (Leopard versions of both have been released) to clear your caches and run the maintenance scripts. It didn't fix the "Scanning..." problem, but maybe it'll improve transfer rates. Maybe? I dunno. It's worth a try and these are maintenance tasks you should be doing anyway

Currently Being ModeratedDec 5, 2007 3:30 AM (in response to dawnrazor)Onyx is freeware (but still BETA for Leopard):
Cocktail is shareware:
There's also this shareware tool called Leopard Cache Cleaner:
