I haven't really downloaded anything over the holidays, so this is something I've just started noticing over the past few days. The problem is that I would be downloading something and my Internet (on my Mac) would disconnect for a split second then reconnect. I wasn't sure if it was a problem with my network or my Mac, but I decided to leave it unless it got really annoying (which it did). I did some digging in my router's settings, messed with the Wireless settings on my Mac, but nothing helped. So yesterday I decided to do a fresh install and see what happens. - Did a fresh install of Yosemite and tested - no problems - Updated to El Capitan (10.11.0(?)) and tested - no problems - Updated El Capitan to 10.11.2 and tested - problem has returned! - Did a fresh install of El Capitan (10.11.0(?)) and tested - again, no problems - Updated El Capitan to 10.11.1 and tested - no problems My 'tests' comprised of me downloading Ubuntu twice (a little under 2.5GB total) and hope for no disconnections. So, for the time being, I'll be avoiding 10.11.2 and hope 10.11.3 fixes this problem. I was just curious if anyone else has experienced problems like this?
