Q: Wifi disconnecting

Every so often my wifi connection will dissconnet but it will still show that I have a full connection. I try to turn wifi off and then back on again but this does not work. Usually there is a list of various wifi connections but when I do this, nothing shows up. I have to restart my computer in order to connect to wifi again. My computer is fairly new and all software is up to date. Can anyone help?

iMac, Mac OS X (10.7.4)

Hi Maria, this has worked for a few...

 

Make a New Location, Using network locations in Mac OS X ...

 

http://support.apple.com/kb/HT2712

 

10.7…

 

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

 

 

10.5.x/10.6.x/10.7.x instructions...

 

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

 

The interface that connects to the Internet should be dragged to the top of the list.

 

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

 

For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

 

208.67.222.222

208.67.220.220

 

Click OK.

 

Also, turn off IPv6:

System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6

 

Or whatever Interface you use.

    To fix the WIFI problem, please proceed in these steps until is fixed.

     

    1. Check if you have problems with another router. Maybe at the library, at a Starbucks, etc. If you are not having problems, then it is probalby related with your router.
    2. Reseting the PROM ( http://support.apple.com/kb/ht1379 ) and SMC ( http://support.apple.com/kb/HT3964 ). If does not work try the next one.
    3. Reset WIFI config: http://osxdaily.com/2012/11/30/resolving-stubborn-wi-fi-connection-problems-in-m ac-os-x/
    4. The airport card may be not properly connected. See https://www.youtube.com/watch?v=UsSIUs7jzQc
    5. The airport card may need to be replaced.  Check https://www.google.com/search?q=macbook+pro+airport+card to find a replacement. Make sure that it is the model for your laptop. Find here the instructions how to do it: https://www.youtube.com/results?search_query=replace+airport

     

    Note: In steps 3 and 4 you are dealing with hardware problems. An alternative to them is to bring the computer to the Apple Store. These steps can ruin your laptops if you are not good with working with circuits boards. A new airport card is less than the $100 that Apple would ask you but if you break your laptop you have a more than $1,000 loss. Attempt these steps at your own risk.
