Connecting 2012 apple macbook pro 10.10.5 yosemite to tv mac osx#

Mac OSX will create new clandestine defaults, but obviously if you want your passwords to friend's wifi etc, backup your keychain. I made this extreme script to wipe out wifi settings and it worked for me, but it is a pain to re-enter ssid/passwords etc and for some reason the problem would show up every now and then.ДЇor me, if wi-fi doesn't work what's the point of having a keychain? I just wanted it to work, so I was willing to wipe things out to make it so. It was a real show stopper when wifi would completely bork on the road as in not letting me connect to open SSIDs. I travel with my laptop and rely on it as my phone. I'm on El Capitan now, but I can relate to your frustrations about the wifi.

I've tried updating the router's firmware to the latest, but it has not helped. I don't think it can run on the 5GHz band. My Wi-Fi router is a Cisco E1200 running 802.11n on the 2.4GHz band. I've tried removing plist files from SystemConfiguration, and I've turned off Bluetooth. None of the other devices on my Wi-Fi network are having a problem. When I'm in my usual location of the next room, ping times go up to hundreds of milliseconds. However, after the 10.10.5 update, its Wi-Fi has become very slow and drops packets unless I'm a foot away from my wifi router. Until a few days ago, its Wi-Fi worked fine. It is a late 2013 Retina model running Yosemite. I've had my Macbook Pro for about a year now.
