You should realize however that 99.9% of Yosemite users have not experienced these WiFi issues at all and do not think this is a "garbage OS".
I would be cautious.
Here's my tale..
Bought new imac a few months ago which arrived with Mavericks installed. Worked like a charm. Ran it for 2 weeks on Mavericks. Wifi fast, responsive no issues. Upgraded to Yosemite and problems started. 10.10.1 Wifi slow, Safari pages begin to load (blue bar gets so far then stops). Browser times out and says can't contact server. I'm annoyed but hey, fingers crossed for 10.10.2 it surely can't make it worse?..... It did.
Under 10.10.2 it sometimes works ok but often get the same website timeouts and disconnects. However it also now sometimes completely drops the connection altogether and also occasionally shows the WiFi symbol with a big exclamation mark through it. Wonderful! Wish I'd stayed put on Mavericks.
Please don't tell me that my network is at fault as wifi worked like a dream under Mavericks. Only thing I've changed is to upgrade to Yosemite which is clearly dog dirt.

So you reverted to Mavericks?
I think I will have to do a full Internet Restore. I really don't want to as I would like keep up to date. I never upgraded my 2006 imac from Tiger and found myself slowly being cut off from everything as OSX advanced.
I will say, however, that I still use my 2006 imac. It boots up in 25 secs, same as the day I bought it. Hasn't put a foot out of place in 9 years. Tiger still runs perfectly. Clearly my mistake was to upgrade the OS...as directed by my computer. Furious.
Thanks for info on router. I'll look into it.
My old imac doesn't meet my needs. Hence I bought a new one. However it works very well as a standalone isolated machine running Logic in my small music studio.
I honestly have no need for a more advanced OS than Tiger and if Apple supported their old operating systems I would be very content. However, I can no longer use itunes or Safari on my old imac and it is not secure for on-line work.
I upgraded to Yosemite on my new mac because I didn't want it to become obsolete and felt that upgrading when the machine was brand new and virtually empty would limit complications.

You could also think about getting a wireless-to-ethernet router. So you have your present wifi station, then you have a wifi box outside your mac, which plugs into your mac via ethernet. Hence, bypass internal wifi.
Then the 10.10.2 upgrade came along and I applied it. I could not keep Wifi working for more than about 30 seconds before losing effective connectivity (the Mac *thought* it was still connected, but no data would come through).
