Wireless issues with Leopard

[Jon55]

Am I the only one having countless problems with wireless dropouts in Leopard (10.5.5)? Wireless works fine under Vista 64 on the same notebook (early 2008 MacBook Pro). I've tried a variety of routers, settings, etc. and nothing seems to work.

I've not a single problem in the countless machines I've dealt with, infact I've had just the opposite experience, generally OS X has much better connectivity than any windows OS.

I would agree, I didn't have any issues with the connectivity either. Could it be a phone company issue?

Hmm, I'm using 10.5.5 at the moment with a Aluminum iMac with a Santa Rosa in it, and Airport is fantastic. I'm at a loss here.

I'm still using my 24" Gen 1 iMac with 10.5.5 and a Linksys WRT350N and have had periodic wireless "issues" as well. I have been disconnected entirely but the network still shows in the list, or I'll be connected but unable to send/receive packets until I turn the Airport off and back on.

My Macbook, one just before this latest alluminum and firewire-less batch, also has 10.5.5 on it but I haven't had the same issue. Though I don't use it near the router, I'm usually in another room.

I just chalked it up to being too close to the router but it's interesting to know I'm not the only one.

I have exactly the same issues - I am fed-up with seeing 'Scanning' the funny thing is that it is only with certain routers. Even more interesting is that while running windows server 2003 through virtual box and using the pass through networking to the wireless - the netwroking in the VM environment is stable, yet as soon as I try to use it in the host I get the drop outs again - even though it is effectively exactly the same connection. Just updating to 10.5.6 now - hopefully it will fix the issue.

N.B. on WEP it seems to be completely stable - it is only WPA that the issues arise. Mine is a 2.16GHZ Mac book Pro. N.B. in exactly the same environments - both my XP Dell X1 and Vista M70 are rock solid stable - so I know it is not interference.

My iBook with OSX Tiger has been having a similar problem lately. Back in June got cable internet with a new router and then come November anytime I open a browser it takes forever to load a page.

I've had similar issues.

What kind of Wireless security do you have going on? I personally have had better luck with WPA2 / PSK. WPA has always been flakey for me.

Edit: also what kinds of routers have you tried?

I've never had any luck with D-link. Netgear's been hit-or-miss, but linksys (so far) are OK.
(And business grades like Sonicwall, Alcatel and cisco work fine)

I was having the same issue with my MBP. Drop-outs, many times it wouldn't connect (or stay connected more than 5 seconds,etc). Switched my router's channel (previously it was using some sort of automatic channel hopping), and the problems were fixed.

I've also read that switching the router to "G" only might help.

Hope this isn't too late to help, but I had this problem (not work on OSX, works fine with bootcamped XPsp3) on my last gen Macbook (4,1), and I tried changing the router channel and a few other things as previously suggested, none of which worked. I took it to the Apple store, and I couldn't get it to connect to their wifi either. The genius installed and ran a software called DNSChanger Remover Tool, which is supposedly a free downloadable app. After she ran that it works flawlessly. I guess it removes some DNS cache or something, which is the cause of the problem, or at least it was for me. Hasn't happened since.

Good luck
