rMBP periodically loses WiFi after sleeping??

[marc55]

My early 2013 rMBP, 2.8/16GB/768GB SSD/Yosemite 10.10.2, has a small WiFi issue, and I'm wondering if any of you guys have experienced it.

Maybe once a day or once every other day when I open the lid to use my MB, there is no WiFi, and I have to select my network. I close the lid a couple of times a day.

It's random, and while not a major issue, it shouldn't be happening, and other than that, I have no problems with the WiFi at all.

Apple phone support has checked everything then can, and recommends I take it in and have the WiFi card tested, which I plan to do.

How do they test the WiFi Card, how long does it take, and is the WiFi card replaceable?

So, have any of you guys experienced this problem, and what was the fix?

Thank you!

EDIT: Router is about 1 year old, and signal does not drop on other devices

My 2012 used to drop signal all the time, I was at the mercy of software updates.

If its only once a day, it might just be your router. Have you reset it recently? Also does it drop wifi on other routers?

I'm not that experienced in OS X yet, but I remember doing some of these with the senior advisor.

I'm the only one who has "Intermittent" WiFi issues?

If so, that's a good sign!

Well, since downloading 10.10.3 the other day, my WiFi hasn't disconnected once; Whoo Hoo!
