Lion WiFi Connection Problem

William, I see you have 13,000 posts so I guess you are an Apple engineer (in disguise). Here is a console log from the recent failed and then successful attempt after Net Diagnostics to get on a FON BST. Notice what is happening from 5:29:44. At 5:32:24 it was able to make a connection after the NetDiagnostics ran. I guess this is where the problem is. I will collect similar logs from connection attempts at other BST tomorrow.

This thread had 207544 hits in December 2009 at the introduction to Snow Leopard. So to me it's not a Lion issue, but as you say, at this moment in time, it is an Apple issue.

My comment about Groundhog Day now seems even more appropriate.

Ciao, anche io ho un imac 2009 ma la cosa l'ho superata.

After installing Lion I had problems with Wi-Fi, reseting SMC did the trick for me: http://support.apple.com/kb/HT3964?viewlocale=en_US

wow. i can't believe it, but this seems to have worked for me! thanks!! 🙂

Just an update for those interested... Several days back I posted a definitive fix that worked for me. If you have not tried the fix I posted, please find comfort in knowing that I have been up and running 100%, no drops, no disconnects since I did the fix - To sum it up, the fix has proven a "fix", not a temporary band-aid.

More amazing is that while THIS post has over 17,500 views, and over 250 replies, the thread I started with the details of the fix has only 88 views and one reply - From what I have read (and I do read ALL the posts) it appears that many people complaining about this issue have NOT tried the fix I posted (only a couple have)

I HIGHLY encourage ANYONE having this issue to try what worked for me - It may not work for all of you, but I am willing to bet that it will work for quite a few of you. My sysptoms were exactly as many here are describing - The fix is simple, no need for a re-install, no need to format drives, and it does not take a long time to do.

Again, I have been up and running 100% since!

If you have tried everything else, what do you have to lose?

Scott

I was on with Cupertino this week. They seemed unaware of an issue with wifi connectivity and Lion. They recommended that EVERYONE with a wifi issue, in addition to posting to this forum, send them feedback.

You can get to feedback here http://www.apple.com/feedback/

Some at Apple believe customers come here before calling tech support, which I explained was NOT the case. Many come here after tech support was unable to resolve their issue.

Good luck.

I removed Lion and am back on SL until they fix this issue.

Must make a living.

Perhaps this problem relates to another older thread on the same subject:

https://discussions.apple.com/thread/2644274?answerId=12703404022#12703404022

There is an answer from Tenortim, attached to the original post, that seems to work well.

Maybe a bit too advanced for the common user though?

YEP - IT WORKS === SOLUTION FOR WIFI CONNECTION ON LION

This looks like the answer to poor wifi on Lion - I have just installed the 10.6.4 kernel extensions for airport as per these instructions and my wifi connection is SOLID. Back to 8011 n only and transmit rates at 300 (max) rather than 8011 n (b/g compatible and transmit rates of 120-130). Also network connect is solid after sleep and shut down, so matfromchicago and earlier posts/threads get the kudos for solving this massive Lion issue.

Follow the instructions here or at https://discussions.apple.com/thread/2644274, and here https://discussions.apple.com/thread/2644274?start=465&tstart=0 (look close to bottom of page) with another post from matfromchicago and more details on the problematic kernel extension.

This MAY NOT solve your particular problem, but it seems to be working for everyone who replaces the Lion wifi kernel extension with the one from SL!!

Neither of those links work for me:

Looks like the new Atheros 9380 cards (new tri-antenna cards in 2011 imacs) weren't supported back in 10.6.4 days...

any ideas on a fix for these new cards? I tried the 10.6.4 kext but no luck...

here is my issue: https://discussions.apple.com/thread/3257143?tstart=0

I also had some issues with WIFI. Have a MBP, late 2010.

Problem was especially when Time Machine had been running while closing the lid. Upon waking up the Mac from standby wifi connection took very long.

This is what solved the problem for me: Resetting the System Management Controller.

You'll find info abut this here:

Hope this might help you.

I just spoke to Apple Support after being extremely disappointed that 10.7.1 did not fix my wifi disconnect on boot or restart problem. Tried a couple of things but the solution came after following this process.

1. Open System Preferences, and then Network.

2. Click on Wi-Fi in the left hand column (make sure the padlock in the bottom left corner is Unlocked).

3. Click on Advanced (bottom right)

4. Under the Wi-Fi tab there is a box labeled Preferred Networks. I had many networks in this box. Select them all and then click on the "-" button. This will delete all the preferred networks. Just a side note, I always have "Remember networks this computer has joined" ticked.

5. Click OK.

6. Click on Apply.

7. Close System Preferences.

8. Restart your machine.

9. This is where things got very exciting, as for the first time since upgrading to Lion the wireless connection actually connected. The Apple Rep then asked me to restart again just to check, and it worked again.

NOTE: I did not have a problem with the wi-fi dropping out once the computer was started. This fix was for a problem with the wi-fi not connecting on Start Up or Restart.

I would recommend Apple Support, they rang me back within one minute and he said that there was a list of things that they could try. He was very helpful and the advice was step by step. The link to the US Apple Express Lane is https://expresslane.apple.com/GetproductgroupList.do

(other countries, choose before you start or you will have to repeat the process). Just continue through the process - it only takes a couple of minutes. The articles didn't help me, so I hit continue, got them to call me and now all is well. Now I can update the family computers and use the same fix if there is a problem. The Apple Support guy also said that I can use the case number to call again and get assistance with the other computers, if they have the same problem.

Good Luck!!

Sorry for delay Kevin, I've been sick. The step by step was on page 38 of this post but now below. Hope it helps but if not call Apple support they seem to be fixing some issues. My problem has remained fixed.

Provate a seguire la guida di tenortim presente qui https://discussions.apple.com/thread/2644274?answerId=12924009022#12924009022

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/thread/2644274?answerId=12924009022#12924009022

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

In das G-Netz komme ich jetzt garnicht mehr rein 😟

Was ich getan habe: Router (TL-WR1043ND) auf WLAN-N Only umgestellt und Channel auf 10, G-Netz (o2 DSL Router) auf Channel 01 fix eingestellt. Zusätzlich habe ich eine fixe IP-Adresse eingegeben.

N Only meint, das "g" Netz der WR ist nicht mehr.

Soll der Mac ins "g" Netz der O2 Box können, musste dieses Netz beim Mac neu anlegen.

Das würde ich mir aber überlegen. Wenn der ein stabiles N-Netz hat, wozu sollte er sich mit "g" verbinden.

Feste IP tut nicht not. Der router kriegt eh immer die selbe und die IP vom Gateway / DHCP Server ist sowieso fix.

ABER er downloadet ganz normal wenn ich Bluetooth deaktiviere - wenn ich es während dem Download sogar wieder aktiviere fällt die Rate sofort wieder in den Keller

Das klingt nach reichlich unerwünschtem Netzwerkverkehr als Bremser.

Könnte tatsächlich der Blauzahn sein, denn Apfel schreibt dazu:

"Minimieren Sie die Anzahl aktiver drahtloser Bluetooth-Geräte, die mit Ihrem Computer verbunden sind oder in der Umgebung in Betrieb sind."

Da hilft wohl nur neue Kanal-Wahl bis ein maximal geeigneter (die wenigsten Störungen) gefunden ist.

Alternativ, falls Kohle zur Hand, 5 GHz WLAN.

Umsonst Tip vom altgedienten Supporter:

Beim Ändern von Konfigurationen oder Architekturen, immer nur EINE Änderung auf einmal durchführen. Dann erstmal Ergebnis checken.

Alles andere bringt nur "Dorschenanner"
