My wifi randomly drops since about 45 days and when it drops; I dont see it showing any available networks. When this happens none of the 5-6 devices connected to that same router exhibit any issue except for this one MBP.
- I did everything recommended in http://osxdaily.com/2015/10/16/fix-wi-fi-problems-mac-os-x-el-capitan/.
- I did a full erase and reinstall of the OS.
- I have now downgraded from El Capitan to Yosemite and even that didnt help.
- Bootup level hardware test tells the
- I took the machine to apple store twice and they say that everything is good from hardware and their ping test per them didnt drop the connection.
- I worked with apple support and they weren't of much help except for saying that its something in your house even after pulling a few wireless connection monitoring files.
- Nothing changed in the house in terms of new devices or ISP or router or modem.
