Air Not connecting to wi-fi-HELP !

AnorexicPig · Jan 2, 2013, 05:33 AM

Hello,
I have a Air mid 2012,and well am on vacations,and my Air just can't find my wi-fi connection.
I have done a reset on the router,restart-shut down the air,tried everything,it will find the network and connect to it for 2-3 times after reset but then again can't find it.
This when iPhones,iPad and a PC are working totally fine.My iPhone next to it shows connected to my wi-fi whereas Air can't find the network

.
It is showing my neighbours connection but not mine

To reset all network configurations move or delete the following folder and restart, keep in mind all network settings are lost so best is to copy or move this folder to the desktop instead of deleting.

/Library/Preferences/SystemConfiguration

If the Library folder is invisible, press Command-Shift-G, a window will open and paste /Library/Preferences/ into the box and hit Enter.

Restart and try again if the problem is solved.

Well I tried this,didn't help,it still can't find my wi-fi network.

Just a crazy thought: Select your location from Apple menu top left (if you have created more than 1).
Then, if you go to System settings > Network is there the wifi networking added for the specific location you have selected ?

I remember something now, do you have any USB 3 device connected to your Mac, they can interfere with Wifi, Apple warns about this and says to not place USB 3 near to the Wifi antenna.
It's a known problem.

But, if this is not the case, try changing the channel on the Wifi router, or completely reset the router.

Um aint the location set to automatic,the problem is it connected to it for 2 or 3 times and after that it can't seem to find that connection when every other device at home can

Nopes,I removed the USB 3 devices too,actually I have given up

.Using my windows laptop for 1 more week am here,then as school starts and I head back,these problems will be behind and next time I will carry my own router with me when I visit home

Out of curiosity, where is the antenna located in a 2012 MBA?

I think they are in the display but I could be wrong.
If you wanna know, go to ifixit to be sure.

Try turning off bluetooth from Sys Pref

I've had this turn up a couple times on our MBA 13. If I turn Wi-Fi off then back on the issue seems to clear up.

I work at a school with 200 mid-2012 13" MBAs. I do notice a few of them occasionally have flaky wifi. I typically cycle the wifi on and off, logout / login, and then reboot if all else fails. Most of the time they'll finally find it after one of these steps. If not, I reset PRAM, run fsck, and if it still won't connect it goes off to the AASP.

I have this problem, i resolved this by going into my router settings and changing the channel from auto to 11.

no worries, great to help out

I've been on channel 11 for years on my apple router, and recently had major slowdowns. Went to channel 3 and all is fine. Always good to check out what channel you are on (and what other channels in your street are using- I used InSIDDer for this, channel 3 seemed the sweet spot).
