OSX Yosemite Wifi issues

Hi there,

I upgraded my Macbook Pro Retina 15" (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn't sync because it can't get a connection and even trying to get to the router config page is extremely slow and hit/miss.

Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.

Are any others having problems with Yosemite? Wifi was working fine on Mavericks.

Tom

MacBook Pro with Retina display, OS X Yosemite (10.10)

Good news here. I changed my Bigpond (Australian ISP) Netgear Aircard 760S to an Aircard 790S and now WiFi is fine with Bluetooth enabled. TX Rate is now 230 Mbps instead of 5!

The new modem cost $240 AUD. I have dual band WiFi enabled, with the main Wi-Fi channel set to 5 GHz and the Secondary set to 2.4 GHz.

Hope that helps someone.

One more update about changing my modem from a Bigpond/Netgear AC760S to AC790S:

I disabled the AC790S dual band 2.4 & 5 GHz mode and set the modem to 2.4 GHz only, as per the config of the AC760S and WiFi functions fine with Bluetooth enabled; download is 45 Mbps which is fine for cellular and the highest I've ever achieved (4G signal strength is 2 bars out of 5).

So perhaps all my problems were caused by a malfunctioning AC760S? Recently it did begin to intermittently drop WiFi altogether.

If you're having trouble using WiFi in any aspect, try a different router/modem even if you router/modem seems fine.

inactive Bluetooth DUN may work, ensure Wifi in top list network order.

I did this yesterday. No drops since. Working so far, and much better than anything else I've tried. Thank you!

I hate to ask the obvious question did you update to the latest version of Yosemite? 10.10.4 Apple fixed the wifi issue in 10.10.3

OK, good luck getting help with your Beta software then... thanks for that though. Consider that Yosemite was in Beta for a long time while this thread was in it's infancy.

Hi osihara,

Look in folder: /System/Library/CoreServices/Applications and try to run Wireless Diagnostics - application from there.

Personally I think your assessment is correct, logically anyway. The common denominator running through the entire thread is Yosemite... Other things seem to be very variable.
