Hi, I've been having weird problems ever since I upgraded my router to the R072 release, but I'm not sure if it's that or the recent Yosemite upgrade to 10.10.3.
Once in a while, at least once a day, Safari will stop being able to connect to the Internet and neither can other programs on my computer *except* Chrome. Dropbox, Creative Cloud in my menubar, Rdio, etc. will start showing that they're having problems with the Internet, but then when I open Chrome it can get to anything. It's really bizarre.
Also, this only happens on my MacBook Air. iPad and iPhone connected to the same network are working fine.
Quitting Safari, renewing my DHCP lease, turning Wifi on and off, etc. won't help. At this point I have to restart my computer.
