New MacBook (2015) won't connect to wifi on wake up or fresh open.
Every time my new MacBook is woken up or when I open it and log in it won't connect to my main wifi. I had thought maybe it was the wireless router, as it has two signals I can connect to (second one labeled ___-5G) and was trying to pull from the stronger one, but they are both the same essentially. I disabled one as a test and the issue remained. I took it to work and the same issue, although the password for the networks are saved and a non issue.
Any advice?
MacBook, OS X Yosemite (10.10.4), (Retina, 12-inch, Early 2015)
