It has been a while since I have used Wi-Fi on my MacPro since I was connected via ethernet. I used to be able to see the Wi-Fi icon in the upper right hand corner of my task bar and I could select a network. Now, that icon is not there and I am unable to select Wi-Fi as an option to add under System Preferences/Network. Wi-Fi is not listed and I am not able to add it on the left side since it does not give me Wi-Fi as an option to add as an interface, only Ethernet 1 and 2, firewire, PPOE and VPN.

 

If I go to Utilities applications and look at System information, it does show that I have a WiFi card.

 

How do I turn it back on?

 

Thank you.


MacPro, Mac OS X (10.5.6)

    Hello,

     

    To find out if it's system wide or user specific, try this...

     

    Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

     

    Does it work/show in the new account?

    Thank you for helping me. I did this and it did not show Wi-Fi under the new account.

    I would Repair Permissions with Apple's Disk Utility, then run the Mac OS 10.5.8 combo update to bring your OS to the current (and last) version of Leopard.  Then I'd Repair Permissions with Apple's Disk Utility again.

     

    If you still don't have the Airport logo on your menu bar, it's time to troubleshoot your WiFi card.

    Good advice, applying the combo may help...

     

    1058 Combo Update, 10.5.8...

     

    http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update

     

    Also, under the Apple icon at top left>more info>Network... is Airport listed there?

     

    Then, Apple icon at top left>more info>Software>Extensions, is there something like this mentioned?

    Thank you both very much. I ran the Repair Permissions and software update says I have the latest version. Still no WiFi showing up. This is the version I have:

    Software  Mac OS X Lion 10.7.5 (11G63)

    Should I still run the combo update?

    Airport is not listed under Network and AppleAirPortBrcm4311 is not listed under extensions.

    My computer is Mac Pro Early 2008 and I verified that I do have an Airport Card so I'm not imagining that it did work at one point.

    Any other suggestions?

    Thanks again for helping me.

    Oh no, your equipment said 10.5.6, which is what we were going on... no such thing for Lion/10.7.x

     

    On my lowly 2007 iMac it's... AppleAirPortBrcm43224:

     

    I think your WIFI card is shot, but...

     

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

     

    If that doesn't help Reinstall the OS.

     

    Didn't used to need recommending Windows type fixes.

    If I restore the partition, it will delete the entire hard drive, won't it? Same with reinstalling the OS? I'm just trying to figure out if I have to make sure everything is backed up and spend all the time getting it configured again. Maybe just running an ethernet cable across the hallway will be easier at this point, LOL.

     

    Thanks again!

    Thank you. What would be the best way or different ways, if any, to troubleshoot the WiFi card?

  • 9. Re: Can't see my wi-fi on mac pro
    BDAqua Level 10 Level 10 (116,475 points)

    Well, it is best best to really, really have a backup, but booting from the Restore Partition should not alter anything, even reinstalling the OS should not remove your data, only erasing or reformatting would.

     

    & yes Ethernet is much prefered for reliability.

    Have tried booting up to restore partition and do the other recommendations but can't seem to get it to work. I'm an old Windows person and have not had to boot up with keys on a Mac yet. How do I do it exactly? Is the other option from Disk Utility? I need dummy proof instructions, please.

    Before you get confused further, be advised that you're posting in the wrong forum.  This is the Power Mac forum.

     

    Power Macs haven't been made since the summer of 2006 when Apple switched to Intel chips.

     

    You have a Mac Pro, that is an Intel machine, not a "Power Mac".

     

    Just keep that in mind when evaluating the replies you have received so far.

     

    The Mac Pro forum is here:
