hey guys,
i have a macbook air mid 2011 with same issue.
after spending long hours on it, i want to share my solution.
first here is my pb and so far what i did to fix it unsuccessfully:
get timeout connection for the past 2 days. sometimes it would connect to it but the pages wouldn't load.but strangely, it will connect to my hotspost shared connection from iphone5 AND iphone4...just not with my modem...
PS: my modem works fine with my phones, ipads, laptops and imac, just not my macbook air
i tried:
- forget the network
- delete the network history from keychain (in disk utility)
- reset the modem ( netgear with optus plan)
- change the channel in the wireless settings of the modem
- smc reset
- pram reset
- shut down the laptop for 2 days and try again
- sleep mode for 2 days and try again
- boot on safe mode
- hold option and boot from the recovery partition then tried internet...still no success.
i spent usless time on the phone with apple and finally called NETGEAR.
we tried couple of things without success until the 2 last manipulations here they are:
- go to your modem settings (http://....), enter your ID and pswd to access the settings.
then go to the wireless settings. i changed my security options from
"WPA-PSK [TKIP] + WPA2-PSK [AES]" to "WEP".
then, on the same page, go down to "Encryption WEP key" ( or whatever is the closest depending on your modem provider) and on the first line "Key 1" enter a NUMERICAL password then click down "Apply".
Go on top,Still on the same page, and change the name of your wireless connection name ( SSID) to whatever you want and click down "Apply".
LAST STEP ( MAKE SURE YOU APPLIED ALL CHANGES MADE IN THE MODEM SETTINGS)
- go to disk utility=>keychain access and fine the line with your old network name ( should have the "A" icon and say " airport network password".once highlighted, delete it.
then click on the wifi icon (top of the screen) and click "open network preferences"=>"Advanced"=>"Wifi" and delete any trace of preferred networks.
NOW try to connect to your wifi with new name and new numerical pswd and that should work ( at least worked for me)
So far i tried ALL the tips and nothing worked.Optus and Netgear blamed my macbook air until i finally did these steps.
the explanation seems to be a conflict in the settings that blocked the macbook from accessing the modem.
Please try and let me know how it goes.
cheers
