    I think it is a shame... you are a network IT person, working none the less at a university... yet you get paid because of what you know and what others don't, at the same time it is your job to maintain a viable network but after listening to your conversations I am seriously thinking to my self: Why do you even bother being in the field your in?

    Why can you not respond to my statement?! LOL.

     

    Not a single time have you even mentioned Lion.

     

    Let's recap:

     

    1) Change your wireless frequency.

    2) Buy a brand new router.

    3) Change your wireless channel.

    4) Totally reload your operating system even after you've upgraded.

    5) DOWNGRADE wireless drivers to Snow Leopard.

     

    My single point is that Lion is flawed. Almost EVERYONE in this thread knows it. There are multiple workarounds, but that's all they are WORKAROUNDS. When things work as they should, threads like this don't exist.

    That is pretty funny... Now your using fallacies... You should not change my words around... at the same time you should go back and re-read what others describe.

    Well, here's another status update. After about 48 hours of successful wi-fi connections, yesterday I noticed intermittent connection problems. but opposed to being spaced out, there were 5 or 6 back to back drops. connect. drop. connect. drop.. etc. Then it came back. Worked about 8 hours. Now this morning: NO WIFI. lovely. just lovely. i'm back to a wired connection and i'll probably just stay that way. I've lost too many hours or productivity messing with this issue. I seriously doubt it's the router for many reasons. I've been on this same router for years; it worked for the last 3 weeks until apple released an update (5 total), my acer laptop can still connect fine, and both of our smart phones can connect. My bf's phone has a great signal.. unfortunately i can set my phone ONTOP of the router and still be better off with the poor 3G service we have here. Again, I'll just run a wired connection until a)apple releases another update or b)i run out of work to do (which will be never) and leaves me free time to "play" with this again. For the record.. although the wi-fi and sharing on this unit stinks severely, i'll never go back to windows

    Hi there,

     

    Yup, mid-2007 24" iMac running a fully updated Lion OS.

     

    My Airport card is:

     

      Software Versions:

      CoreWLAN:          2.1.2 (212.1)

      CoreWLANKit:          1.0.2 (102.2)

      Menu Extra:          7.0.2 (702.1)

      AirPort Utility:          6.0 (600.92)

     

      Interfaces:

    en1:

      Card Type:               AirPort Extreme  (0x14E4, 0x88)

      Firmware Version:     Broadcom BCM43xx 1.0 (5.10.131.36.11)

      Supported PHY Modes:          802.11 a/b/g/n

      Supported Channels:          1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108,112, 116, 120, 124, 128, 132, 136, 140

     

      Current Network Information:

    Time Capsule (5 GHz):

      PHY Mode:          802.11n

      BSSID:          90:84:0d:dd:a8:b0

      Transmit Rate:          243

      MCS Index:          14

     

     

    Please note, for other readers, this (above) is a STABLE combination.

    My Mini (also mid-2007 running a fully updated Lion) is on the other hand as follows and is NOT stable:

     

      Software Versions:

      CoreWLAN:          2.1.2 (212.1)

      CoreWLANKit:          1.0.2 (102.2)

      Menu Extra:          7.0.2 (702.1)

      configd plug-in:          7.1.2 (712.1)

      System Profiler:          7.0 (700.3)

      IO80211 Family:          4.1.2 (412.2)

      WiFi Diagnostics:          1.0.1 (101.1)

      AirPort Utility:          6.0 (600.92)

     

      Interfaces:

    en1:

      Card Type:              AirPort Extreme  (0x168C, 0x86)

      Firmware Version:          Atheros 5424: 2.1.14.9

      Supported PHY Modes:          802.11 a/b/g

      Supported Channels:          1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140

     

      Current Network Information:

    Time Capsule (5 GHz):

      PHY Mode:          802.11a

      BSSID:          90:84:0d:dd:a8:b0

      Channel:          60

      Country Code:          SE

      Network Type:          Infrastructure

      Security:          WPA2 Personal

      Signal / Noise:          -73 dBm / -96 dBm

      Transmit Rate:          36

     

     

    So, given these two profiles I'd be looking at the interface comparisons.

    Possible problems with the following:

    - Card Type

    - Firmware versions

     

    Does anyone else with issues have the following airport card/firmware combo??

     

      Card Type:              AirPort Extreme  (0x168C, 0x86)

      Firmware Version:    Atheros 5424: 2.1.14.9

     

     

    It'd be nice to see some factual technical information in these discussions instead of speculation, so we can try to pinpoint the issue; a failing card type or firmware.

     

    Thanks for playing!

     

    Andy

     

     

    Edit: The Atheros driver gets a LOT of mentions as the failing component here: http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/. Recomendations are to revert back to the Atheros driver from Snow Leopard:

    A lot of people have posted specs early on in the thread.  I know I did.  The problem is all sorts of configurations are having the problem, and while you have people in the thread who disagree, Lion seems to be the common element.  There are exceptions which is what you seem to be (2 Lion machines, one working one not), but most people on here had no issues until updating to Lion, and their networks are performing fine with mulitple machines.   I guess the main problem is, there are multiple problems going on.  There are people with the sleep issue, people with constant drops, people unable to get any wi-fi connections at all....

    Lion as a whole isn't the problem, I'd gamble on it being specific firmware drivers in possible combination with certain card types, since in my case I have only had this issue since upgrading to Lion and ONLY on my Mini, which has the Atheros firmware.

    This appears to be a decent suggestion to roll back the problem Atheros firmware to Snow Leopard: http://rys.pixeltards.com/2011/09/04/osx-lion-wifi.html

    I'll be trying this and will post the results.

     

    It'd be great if people can simply post their card & firmware versions we might actually get to see some correlation here since the actual end symptoms can vary so much based on installed software etc.

    • I too have the issue where setting my router to Wireless B makes the connection stable. But then sometimes it just goes haywire, disconnects and reconnects 40 times in a few minutes. I just don't have time to take apple back at the moment as working on borrowed time. It just cut out now trying to submit this post.

    Firmware Version:          Atheros 9380: 4.0.58.4-P2P

     

    The problem I was having, and on a brand new late 2011 iMac as soon as I started running it, was constant drop-outs.  They would happen literally every few minutes.   I was somehow able to fix the problem, but I only have a theory on which fix in the thread finally did it.  I believe it was the combination of erasing all keychain info for networks, making a new location, and renewing DHCP lease.  It's worked fairly well since that.

     

    Also, I have not installed the last 2 updates.  2 many reports in the thread of people who got the problem fixed, then started having issues again after the updates.  I lost days of time trying to troubleshoot the problem and have no desire to go through that again.  I will not update my machine until I have it hardwired as a backup.  I have to run some cable to do that though.

     

    If you want a really odd issue, everytime I open system profiler to view WIFi info, I lose my connection.  It just happened again when I went to get the info to paste here.

    (see my solution above.) I am willing to bet others have a similar problem, where the network is cranking out only in N and their computers are set up for B or G either because of the wifi card installed or because of some settings.

    So that is a problem... why is your computer only using B...  take a look at your PHY mode: 802.11b.

     

     

    What type of router do you have?

    Is this information from your system information under network next to wifi?
