So after upgrading to Yosemite 10.10.2 (10.10.0 & 10.10.1) the wifi issues continue!!!! when I turn my mac on I go into safari and launch a webpage... about 20 seconds later if I click a link the page will not load at all! I then try to access my NAS drive I cant even browse that either!!! if I disable my wifi then the enable it again and try the above it does again the same thing! ive also tried deleting my wifi profile and reconnecting to my Sky Hub router and has made no difference! this is really p***ing me off! I spent 1700+ on my MacBook Pro Retina 13" for something that doesn't work. so all you MacBook users please can you help me try out! Im at selling point!
