Yosemite 10.10.5 Frequent Wi Fi Drops
My brand new MacBook Pro with Yosemite 10.5.5 drops Wi Fi constantly.
As often as several times per hour, my Wi Fi signal is still there but I lose all Internet connectivity.
- I have had the cable company replace the router (now using a brand new Ubee)
- I exchanged my previous brand new MacBook for another new one, same problem, right out of the box
- I tested this Mac on another ISP at a coffee shop for hours -- had some slowness due to their connection but never a drop
- Turning Wi Fi off then back on again on the Mac reconnects me every time
- Sometimes just waiting reconnects me as well, but it could be 2 mins or 20 mins, so I usually just restart Wi Fi on my Mac
- Very little extra software is installed -- pretty much a stock machine for software development, using Coda.
- Have run the Wi Fi diagnostics and watched the graphs, don't really see much of anything except "UNEXPECTED DROP DETECTED!!!" in the diagnostics log.
- Changed my DNS to Google, in the off chance my ISP (Cox) happened to have some weird DNS issues, coincidentally right when I got this new Mac.
- Also note: my iPhone %sdoesn't drop, nor does my iMac, and my older MacBook Pro (2010) didn't either. This only started on my brand new MacBook Pro with Yosemite.
- I've set my router to a preset channel on 2.4GHz. There are around 23 signals in the area, evenly split between 2.4GHz and 5GHz. I'm the only one on my channel
I do find it odd that I didn't get a single drop at the coffee shop, which would make me think it's my ISP. On the other hand, they have replaced the router and my other devices don't drop, which makes me think it's this Mac.
Needless to say, this makes software development very very difficult. I have a ticket from Apple support but that goes nowhere because they really don't like to admit it could be Yosemite or hardware. And yet I see countless posts with others having a similar issue.
Could this be a production problem? Or is it Yosemite? Why is it so hard to get Apple to diagnose this at a higher level? Wireless diagnostics are producing a TON of data, why can't they analyze this?
Or could it be my ISP? How do I even debug this when everyone points fingers? Shouldn't there be a way to pinpoint this?
