Q: Lion WiFi Connection Problem

Seeing as you are so smart to know that it is NOT a Lion issue, why not finish by telling us what the issue is.

"The developers are not going to get much out of reading 46 pages of comments unless each comment is short and concise about what works or doesn't work, and what steps you've tried."

Except that the developers nor tech support read this forum. Only feedback via AppleCare phone support, the express lane or a genius bar appointment is looked at for such things.

Hi i have tried all 13 wifi channel of my router and channel 1 and 2 (but channel 1 at all) seems to be the more stable and i got just some disc. in a day)...

The problem btw is still here...

Please say what wifi router u are using this may be useful!

Alice Gate Wifi plus 2 for me (seems to be infineon chip)

Someone might try to use different wifi router? (Just to try)

How does you post solve any problems? "Wait and See" does not contribute. All it does is let others find and solver the problems.

Yes. I was even having problems with my Apple airport. I tried reloading the software onto the airport and still could not connect. I reloaded Snow Leopard and surprise, surprise. The airport worked with the new settings! I have not solution, just frustration.

Scrivo dall'Italia: anch'io uso un Alice gate 2 wi-fi plus e nessuna delle soluzioni, nessuna, proposte in 47 pagine ha funzionato, neanche quella di cambiare i canali del router Alice.

Il mio Airport extreme sul mio IMac ha firmware Atheros 9280 e non funziona....invece sul mio Mac Book che ha Firmware Broadcom BCM43xx 1.0 tutto funziona alla perfezione sulla stessa rete wi-fi: quindi non è un problema di router ma, molto probabilmente, di driver e di Lion, perchè con Snow funzionavano entrambi.

Apple non ha ancora risolto il problema e questo è grave!

Buona giornata!

Assolutamente d'accordo, il problema é Atheros 9280 con Lion. Confermo, nessuna soluzione proposta in 47 pagine risolve il problema. Sarebbe possibile effettuare un downgrade del firmware del Atheros 9280 alla versione presente in SL?? Quale versione del firmware é presente in SL?Mi sembra di aver letto qualcosa di simile qualche pagina fa...

Inutile esporre tutta la frustrazione nei confronti di un problema del genere.

....finalmente qualcuno che mi dà ragione....

Il mio IMac è del 2009 quindi il firmware è meno recente....se con la versione 9380 funziona, basterebbe un aggiornamento firmware.....ma io aspetto da 40 giorni che si muova qualcosa!

Finalmente abbiamo scoperto qualcosa...speriamo in bene!

Buona giornata!

Hi.

Me too from Italy.

Same situation of previous ones: Firmware Atheros version 9280 and Alice gate 2 wi-fi plus.

Same result: the problem is still there :-(

I've noticed something else about these strange Lion dropouts.  When my Lion iMac drops it's wifi connection, it seems to be corrupting all the other devices on the network, which simultaneously lose their connections as well. The other devices (non-Lion) can only rejoin once the iMac reconnects (sometimes on its own, sometimes by toggling wifi power).  If I put the iMac to sleep all issues with the other devices go away.  Very strange...

Adding a new network location andsetting a manual IP address resolves the issue with me on some routers, otherwise maintaining a constant 'ping' seems to maintain the connection in some situations. A few other ideas here:

This clearly only effects some routers and Mac combinations, but I can't find any consistency between brands other than Linksys being the most reliable.

Provate a seguire la guida di tenortim presente qui https://discussions.apple.com/message/12924009#12924009

Viene utilizzata la versione del fw atheros presente nella 10.6.4 (volendo anche della 10.6.8 la procedura é la stessa basta scaricare il 10.6.8 combo update).

Questa guida ha funzionato per tutti quelli che avevano problemi simili con una precedente versione di SL dove veniva aggiornato il firmware dell'Atheros e serviva a fare il downgrade. Teoricamente dovrebbe funzionare...

Ho provato questa procedura ma in "Informazioni di sistema" leggo sempre la stessa versione " 4.0.55.4-P2P"...

Fate una prova con questa guida che ho linkato

Try to follow the guidance of tenortim present here https://discussions.apple.com/message/12924009#12924009

It uses the atheros version of the fw present in 10.6.4 (also 10.6.8wanting the procedure is the same, just download the 10.6.8 comboupdate).

This guide has worked for all those who had similar problems with a previous version of SL where the firmware was updated dell'Atheros and served to make the downgrade. Theoretically it should work ...

I tried this procedure but in "System Information" I always read the same version "4.0.55.4-P2P" ...

Give it a try with this guide that I linked

Va bene tutto, ma perchè non sistema Apple?

Io non voglio pasticciare sul mio computer e magari combinare qualcosa di male!

Comunque ho verificato sull'ultimo back up che ho di Snow Leopard il Firmware era il: 9280.2.1.4.6 e funzionava: questo conferma che con Lion il nuovo Firmware non funziona.

Io farei qualcosa solo se fosse possibile fare un aggiornamento o un downgrade solo del Firmware.

Buona giornata!

Hi Installed Lion and it caused so many problems i could not believe that it was an apple product, Time Machine does not work, none of the remote apps on our 3 phones in the house work my Apple TV's don't work, iMac will not connect to internet on waking, every thing i try to fix i only make other things worse! have given up till Apple patch this piece of crap. Got the Mac working to a degree but when i come down in the morning i have to clean up the mess from wake up, i moved away from PC because of this kind of thing! wish i was still running SL but am not brave enough to revert i may not have a fuctioning Mac after!
