Q: How do I check my wireless card?

Macbook Pro, 10.7.4,  8 gig ram, two AirPort extremes.

 

All software is up to date.

 

The background.

My ISP went belly up 2 days ago and once I hardwired my Macbook pro into my modem I was off and running again. However, I have been having trouble connecting to the Internet for the last couple of days wirelessly. I have shut everything down and rebooted, several times, but as soon as I turn on my wireless I loose my connection to the Internet. I have a technician coming to check my Optus modem tomorrow. To complicate the matter, when I arrived at work today the same thing happened with my computer and the connection to the Internet. My airport utility says I am not connected  to the Internet where as every other computer at work is.

 

Now with an Ethernet cable connected I am able to connect to the Internet.

 

From this I deduce there may be something wrong the wireless card in my own Macbook pro. How do I check this out and what steps can I take to remedy the situation?

MacBook Pro, Mac OS X (10.7.4)

    Call Apple Care if you have it.  Your "deduction" would be a hardware issue and should be properly diagnosed by a repair tech.  Otherwise, take the computer to an Apple store or an AASP.  Whichever is more convenient for you.

     

    Take FULL advantage of your warranty.  Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired. 

     

    In case it is not a hardware issue -

     

    Change your router channel.  Sometimes this is all you will have to do.

     

    Power cycling the router.  Read the router's user manual or contact their tech support for instructions.

     

    System Preferences/Internet & Network/Network

    Unlock the padlock

    Locations:  Automatic

    Highlight Airport

    Click the Assist Me button

    In the popup window click the Diagnostic button.

     

    System Preferences/Network- Unlock padlock.  Highlight Airport.  Network Name-select your name.  Click on the Advanced button.  Airport/Preferred Networks-delete all that is not your network.

    Place a check mark next to "Remember networks this computer has joined."  Click the OK button and lock the padlock.  Restart your computer.

    No internet connection (wireless)

    Check to see if an extra entry is present in the DNS Tab for your wireless connection (System Preferences/Network/Airport/Advanced/DNS).

    Delete all extra entries that you find.

    Place a check mark next to "Remember networks this computer has joined."
