os x 10.10.3 installed and wifi slowed down

I installed OS Xver 10.10.3 last night and now my wifi connection has slowed down. Connections very slow or drop out. My wifi is working. Did the update cause these problems?

I'm running a 60-person office, all Macs. There's no denying that an inordinate number of the systems here that have upgraded to 10.10.x are experiencing new wifi issues. System will be fine at first but will soon slow to a crawl. Turning off and then back on wifi resolves the issue for a while.


I've done all of the voodoo - zap PRAM, run Onyx to clean up prefss, rebuild DBs, etc. Nothing fixes this. I'm hiring a wifi specialist to come in and audit our system but, considering that these problems seem to have arisen w/ 10.10, I'm not sure I can blame the wif


This is ridiculous - Apple needs to fix its $h!t.
