OS X Yosemite 10.10.5 Wifi Problem

Do you have this problem on all networks, or only one?

WWell I guess we have to wait till Apple releases a new upgrade for this software and hopefully it will fix this stupid issue.

meanwihle my laptop is just a room decoration.

BY the way, try this maybe it will work for u.

in terminal: sudo ifconfig awdl0 down

hit return and enter your password if prompted

thats ( a w d " L lowercase, and Zero )

let me know if it works for u

sudo ifconfig awdl0 does not work for me...

I have the feeling something is not right in 10.10.5. Here is what I get in Wireless diagnostics monitor. Since 10.10.5 (or better some days after upgrading) I need a much stronger signal than before to have an acceptable connection. I used this MBP mid 2012 non-retina for almost 2,5 years basically in the same environments and now it is not working anymore. Any help would be greatly appreciated.

According to your performance graph, you signal quality form your WiFi router is lousy. And your noise levels are up.

RSSI Signal quality in the -80's approaching the -90's is almost no signal at all. And when the noise is stronger than the RSSI signal, that is no good.

Do you have another Mac that you can measure signal quality to see if it is just your 1 Mac or if it is common such as your home network setup.

Keep in mind that radio signals have to exist in a world where other signals can affect them. Things that are out of your control, such as neighbors and what they add or remove from their networking equipment.

Thanks BobHarris!

Sorry, I forgot to mention that other Macs are still working fine in the same environment.

I was trying to ask if the Wireless Diagnostics performance display looked the same or different from the display you just posted, if you run them side by side
