Mac OSX Lion disconnect issues
Hi,
Running a site with 16 MSM-430s APs and daily around 3-400 concurrent users. Windows, phones, iPads and whatnots connect without issue.
But Macs running OS X Lion have tons of issues. Some days things just works, other days they can connect for about two seconds, get an IP address and then promptly disconnect. The console on the mac says "Beacon Loss Event" and "Airportd Timeout".
The SSID in question has no wireless protection. I created a new VSC that has exactly the same parameters as the previous one except a new name and a WPA key. This seems to work flawlessly on the Macs.
Is this a known issue? Is there a fix? We would prefer to run the VSC without wireless protection as this is a public network in an educational institution.

Re: Mac OSX Lion disconnect issues M1522nf Laserjet
Hi,
I'm not sure if my issue is the same. I run 4 devices ( 2 Macbooks, Iphone and Ipad) off an Airport Extreme base stateion network. Recently my HP Laserjet M1522nf keeps getting disconnected from the network. It shows up on the Mac as idle, but I can't print or scan anything untill I power off the printer and restart.
Any suggestions on how to fix this?
Many thanks

Re: Mac OSX Lion disconnect issues
Hi all
Please be aware that OSX Lion seems to have issues with wireless networking. Apple discussion board (and others) have numerous postings describing inexplicably dropping network connections. There are also numerous articles around the Internet describing what to do to resolve them. It might be also a good idea to contact Apple support about this.
HTH,

Re: Mac OSX Lion disconnect issues
We have the exact same issues.
We had a consultant from our hardware provider out to check the problem, and as far as we could see it was related to dhcp somehow. The Mac would get an IP, and shortly after get rejected by the controller again.
Is there any news on this problem? We have spend really many hours to try to solve this issue.
Extra note: I should say, that the problem only accours on a VSC secured by WPA. We also run 2 unencrypted guest VSC's using HTML login, and here the Macs can run without any problems, other than having to put in user credentials every time they want to connect.

Re: Mac OSX Lion disconnect issues
Older codes had some problems. 5.5.3 and older release and 5.7.0.0 releases, weren't the greatest.

Re: Mac OSX Lion disconnect issues
We run firmware version 5.7.1 on the MSM 720 controller, and 430 AP's, witch should be the latest version.
Actually these problems started when we upgraded the firmware, to get rid of problems with 5 Ghz band.

Can you tell me your support case number please so that I can check on this?
Thank you.
