#57771 — No WiFi on Wake-up in Mavericks

So my late 2012 iMac was rocking along just fine until I upgraded to 
Mavericks.

Now, about half the times when it comes out of sleep mode, it doesn't 
find and connect to my WiFi. I either have to find my SSID in the 
networks list or manually turn WiFi off, then on again in system prefs 
and it connects.

And yes, I've got the "Remember Networks Joined" box checked and have 
tried both checked and unchecked for the "Ask to Join New Networks" box. 
I've also tried broadcasting and not broadcasting SSID in router setup. 
No difference on any combination of these options.

I'got an older Mac Book Pro, upped to Mavericks, and I have the same 
problem exactly -- frequently have to turn the WiFi on and off to get it 
to connect to my WLAN. It's not a major problem, and they (Apple) may or 
may not fix it, but it's annoying.

I have an even older Macbook Pro (32-bit CPU) running Snow Leopard, and 
it does the same thing, too. Never have found a way to "fix" it. :-(

Mine never had the problem wit 10.7.5.

I have an iMac (2012) but it's hard connected, so I don't know if it has
this problem. The 2012 and 2009 MacBook Pros do not, however.

I had the same problem, and tried a variety of the suggested fixes 
(including trashing various preferences, some of which were hard to 
find), with mediocre success, until I stumbled on the solution (for me) 
near the end of one long thread.  The problem was that Bluetooth 
interfered with wifi.  I don't use Bluetooth much but had accidentally 
left it on once.  So I turned it off and have had no problem since.  As 
I recall, the articles said the problem arises only in some hardware 
models -- I thought it was only just some laptops but it could be iMac's 
too.  I don't know what people who need to use Bluetooth can do.  In any 
case, it's surprising that the Mavericks upgrade caused the problem, but 
I suppose it has something to do with various wifi or Bluetooth rf 
parameters that got changed.

A ditto on that one.  Ted's persistence and discovery of the bluetooth 
connection solved the problem on my mid 2012 13" MacBook Air.  It was 
not a problem on an older 17" Macbook Pro or a core 2 duo 11" Macbook Air.

I don't know if you posted those details before, or if I overlooked 
them, but it's interesting -- you'd think that even if they are still 
perhaps a couple of years apart that the 13" MBA and 11" MBA would have 
the same hardware for wifi and BT, and I'm assuming it's a problem 
mostly caused by particular hw in conjunction with Mavericks.  In any 
case, that might explain why the problem wasn't fixed by the Mavericks 
update -- the folks at Apple might have tried to reproduce the problem, 
but didn't use exactly the right hardware.

I don't think I'd mentioned the other Air before.  It's a late 2010. 
Perhaps even bluetooth or wifi hardware changes enough to cause a 
problem.  Both support 802.11n.  The bluetooth chipset in the 13" model 
is listed as Broadcom 20702A3 and the one in the 11" older model is 
Broadcom 2070B0.  I would think the folks at Apple would have known 
that.  At any rate, I'm hoping they clear it up eventually.  Luckily I 
rarely use bluetooth in the 13" model so it's not a big deal to leave it 
off all the time.

So it sounds like I'll be having this problem until Timbo decides to fix 
it...

Did you find out whether Bluetooth is the root of your problem?  If so, 
and if you need Bluetooth, you could try to write a script that would 
turn bluetooth off on wakeup and turn it back on when the wifi link has 
been re-established.  In my few experiments I discovered that turning 
Bluetooth back on after the wifi had reconnected didn't interfere with 
wifi too much (although I believe it did some.)  It may also depend on 
what mode of wifi you are using -- wifi n seems to periodically 
renegotiate the wifi parameters and if bluetooth is on I think it may 
sometimes end up in a poor state.

I'm on an iMac with wireless mouse and keyboard so I do need the 
Bluetooth...and unfortunately script writing is above my pay grade...

Kinda discouraging that I'd need to do a kludge work-around like that to 
get the operating system to do what it's supposed to. I thought I'd left 
all stuff that behind me when I switched from Windows to Mac a couple of 
years back:-(

I have this same wifi problem, and I have never had bluetooth turned on 
on the MacBook Pro.

Sounds like a marginal wifi connection. Have you tried working on that?

It wasn't marginal before I installed Mavericks;-)

It'd been a rock solid connection to my iMac for three years-- and still 
is to other devices elsewhere in the house.

I take that as a good sign. If the problem started due to a software
update, it very may be solved with another software update.

The question is, do you want to fix the problem, or just complain about 
it? If the former is the case, try running Wireless Diagnostics (see 
http://support.apple.com/kb/HT5606) and see if it tells you anything. I 
don't doubt that Mavericks brought the problem on, but you might as well 
see if you can fix it rather than waiting hopefully for a software 
update.

Thanks for the tip. It said all was OK.

One more stab. Try running iStumbler (it's free, donationware). It will 
show you signal to noise ratios, possible competing signals, etc. There 
might be a clue there. Incidentally, it shows me that there are 15 
different wifi signals being received by my computer, many of which are 
quite good enough to use, and that some of them are open. Why am I 
paying for internet access?
