Q: Since El Capitan WiFi goes On and Off, Then Off until restart!
I have had this issue for awhile now! My wifi will turn off then on and again until it goes off and i can't turn it back on unless i restart my macbook pro. And even after i do so the time my wifi works for is not predictable. Sometimes 5 minutes, others a day. I have tried every trick i could google. First i ran full diagnostics with ethernet cable plugged in to make sure no hardware issues. Came up clean. Then i tried to clear NVRAM and SMC.....no help. Afterwards i saw some people had wifi issues resolved in Yosemite by deleting the content of /library/Preferences/SystemConfiguration folder and restarting so macbook can reconfigure itself...not really sure. No help yet again. I was told to back up my macbook and clean wipe with a new OS X instal but that will cost me money for an external hard drive and lots of time reinstalling cad software, parallels, windows....etc. Someone please help me! Last i heard to start the macbook in safe mode and run another type of diagnostics but i haven't done it since the instructions weren't clear and i need my macbook for school. (This is honestly a very annoying issue because it is caused by Apple software. I was told i would have to pay to get it fixed at the apple store and it's Apple's fault my macbook is not working. This has set me back in school work and personal business. I honestly wish i had enough money to file a lawsuit.) Any help would be nice!
MacBook Pro (15-inch Mid 2012), OS X El Capitan (10.11.1)

After I made the last post on here i went to go pick up my mac book and while talking to one of the employees from their tech team he recommended we run another short hardware test while my computer was booted in a Yosemite client profile which they have at apple. The problem persisted and after running a short test my airport card hardware failed. Keep in mind that this computer ran through an extensive hardware test and passed the day before! I was furious of course because i was just told there were no hardware issues. We proceeded with a repair of the airport connector and then the airport card itself! My wifi now works with El Capitan! I am glad the issue is fixed but i will be back to post again in a week since i've only had my computer back for a couple of hours now. Need to run the wifi for some time to guarantee it wont go bad again, which would mean it is really a software issue!
