Yosemite 10.10.1 update did not fix my wifi issue, did it fix yours??

My WiFi problems on a Mac mini 2014 with Yosemite are solved. The external USB 3 SSD was the cause of the problem. I moved it away from the Mac mini and used a different USB port (that one besides Thunderbolt) - and WiFi works fine now! More here:

Mac mini (2014) WiFi Connection Problems

No solution with 10.10.1. Still dropping wireless with my MBP since upgrading to Yosemite. Flawless with Mavericks using a TC.

There’s an excellent app available in the Mac app store. It’s called WiFi Explorer ($3.99.) When you launch it brings up every WiFi signal your Mac can detect, along with signal strength, channels used, and statistics regarding connectivity. If you live in a concentrated urban area there may be dozens of WiFi networks in use. With WiFi explorer you can troubleshoot by changing channels, moving stuff around (like your SSD) to see what happens to signal strength. It will also tell you what 2.4GHz and 5.0 GHz networks a/b/g/n/ac signals are reaching your Mac’s WiFi antenna. Always remember that WiFi is a radio signal at its core and radio signals can be tricky and hard to troubleshoot.

The issue is not with signal strength. The issue is with the OS somehow causing continual dropouts, restarts, and extremely slow speeds on the network, even when the tested BPS speed is high and even when the connection is excellent.

Whatever you say. Good luck.

I think you're right about the interference issue, only when setting the airport channel, (through the terminal for example), the setting is ignored. Also when you have multiple routers with the same network name, you cannot select a specific BSSID. Is this something that Wifi Explorer allows you to do?

You can be dismissive about this, but I have experienced the same problem, excellent signal strength, but still extremely low band speed. Also there is a good video (http://youtu.be/b48jyGwjaoY) demonstration that shows how difficult it is to pin this problem down to just signal strength.

You have to understand that a lot of us had perfectly working Wifi before the Yosemite upgrade. And personally, I have several other devices on my Wifi network. The only one that's making problems is my Macbook.

Exactly. My MBP NEVER dropped a signal when running Mavericks. Only now is it dropping the wireless completely and can only recover when turning the wireless off then back on. My connection is not slow. But, it's impossible to do work given the random dropping of the wireless connection

I have the same problem with wifi disconnecting but it is only happening with my 2011 MacBookPro. This is running 10.10.1 as is my iMac , which does not experience the problem. I have tried to run AHT on my MacBookPro but I cannot get it to fire up however long I stay with the D key pressed.

I understood the wifi disconnect was a known problem which 10.10.1 was supposed to fix.

I am on Retina 15" Mid 2014 running 10.10.1 (14B25)

Connected to Unifi AC access point WPA2 Enterprise with Radius Server ever since 10.10.1 Constant disconnects. It wasn't that bad 10.10.0

I tried many solutions above deleting config files etc... nothing works.

I have tried all the fixes in this forum and I am still having the same WiFi problems-- slow, unstable, spinning beachball in both Safari and Firefox. OS 10.10,1 did not help.

Never had this problem before updating to Yosemite.

anyone tried the steps here?

"Exactly the same problem here. Wifi was working perfectly but update 10.10.1 has just killed my connectivity (Hate myself for updating and trusting in advance!!!) Obviously I won't be able to print until Apple or somebody comes to the solution for this problem. This is creating lots of problems for my work. Any help will be greatly appreciated."

This is a bad update from apple.

I didn't any problem untill this update --" (i have to use ethernet ...)

(macbook pro late 2011)

I still have the problem. Have gone back to Ethernet connection and turned wife completeley off. I turn it back on to print.

I have two iMac's in the same room, where the router is. One works ok, one will only stay connected if plugged in to router.

Does ANYBODY hear us???
