    I have the latest beta build of Yosemite (10.10.2 build 14C81F), went to sleep and left some files downloading. When I returned in the morning the download was interrupted. Couldn't figure out why, until I saw the WiFi icon turned off...

    Why is this issue still not resolved? Thought they made several updates just to fix it. This doesn't happen to me at all on my Mavericks partition, but happens several times a day on Yosemite.

    btw, Merry Christmas Macrumors :cool:

    More Information please

    Could you please deliver more specific information please:
    - Model of Mac?
    - Brand and model WiFi access point?
    - Are there iOS devices (including Apple TV) associated to the same network?
    - Have you tried WiFriedX?

    I suspect the whole WiFi mess is based on low-level driver or even hardware problems related to the used Broadcom WiFi chipset. One plausible reason can be found in the article from Mario Ciabarra (link below). This would at least explain, why Apple is unable to deliver a fix within reasonable time. Apple should at least provide a user selectable choice between reliably WiFi operation (as in Mavericks) and the availability of the key features from Yosemite. But Apple will never confess a failure like that.

    Both me and my 2 co workers own a mix of macbookpros 13" from late 2013 to 2014 all upgraded to Yosemite since release and we have never experienced wifi issues. And we work on wifi the whole day, every day of the week. Access points at work are Ubiquity. No wonder why is a hard nut to crack for Apple.

    Oh, I forgot to include details of my Mac lol...

    Mac Mini 2012 i7
    WiFi from Time Capsule
    Nope, no iOS devices or Apple TV connected.

    Never heard of WiFriedX, definitely gonna try it out! Thanks a lot for the article, just found out I had AirDrop with the "On Contacts" option on, already turned it off, never use it. No idea it affected WiFi!

    Try turning Handoff off. I'm pretty sure it is the additional BT traffic associated with Handoff that is causing additional interference with and degradation of WiFi.

    I can't think of any other issue associated with Yosenite that wouldn't be fixed with a relatively simple driver reversion to whatever driver worked with Mavericks. As users report reverting to Mavericks resolves the issue it can't be hardware - and it doesn't seem to occur on non-Handoff capable Macs.

    This would not be possibly without loosing some of the new key features of Yosemite. My guess is that Yosemite with its Apple Wireless Direct Link (AWDL) interface uses the WiFi chip in a different way than Mavericks. Possibly this doesn't work in practice as advertised by the chip-maker. There might be yet undiscovered bugs in the chip-silicon that cause interferences or glitches. These kinds of issues could be hard to discover as they're possibly related to the wireless environment.

    I for myself haven't had any WiFi issues with Yosemite. I'm using a Mac mini Late 2012 Quad-Core and an Apple Time Capsule 802.11ac. I've configured two separate SSIDs for 2.4 and 5 GHz with manually selected channels 6 and 44.

    But I still have WiFi issues with iOS devices using the 5 GHz WiFi. So I've associated them to the 2.4 GHz WiFi.

    That is my point, turn off Handoff and it may avoid the extra BT traffic. BT is well known to interfere with WiFi but "normal" BT traffic to peripherals shouldn't be enough to degrade a WiFi signal, Handoff may be moving more data though, hence more interference.

    Handoff was already turned off, so I think that was not the issue in my case. WiFriedX installed and running. Will update on my situation, but hopefully that may have fixed it.

    Thanks!!
