Q: mac osx 10.9 Mavericks wifi issue

Apple does consider this a wide spread problem if you talk to Apple Wirelss. I have talked to Apple Care (I have a mid 2013 AIr) and they were pretty clueless. When they sent me over to Wirelesss then then I got a different story altogehter. I stated this in an early post. They said they had multiple fixes to work on. My issue is maybe resovled but I have to use it more. The reason I say that is if i wake it up far enough from the base station it will go to 2.4 like it should becaue with a weaker signial it switches to 2.4 from 5 Ghz. But if I wake it up close the base station it should go to 5 GHz automatically. I just got 10.9.1 yesterday so I am not sure. But Apple Wirelss told me they have  a much bigger issue with siganls being dropped and total loss of connection and that problem I have not had.

My problem was, hopefully past tense, is that my connection would never go to 5 GHz unless I shut off and turned on the wireless manually. All day yesterday it seemed to come out of sleep and go to 5 Ghz like it did before I downloaded Mavs.

Turning Bluetooth off has resolved it for me too.

¿What should I do now with the keyboard and the mouse?

I have a working solution!

While visiting the Apple Store in Kansas City, MO, I was informed that this problem is not exclusively tied to Mavericks. It specifically has to do with corrupt system configuration files, which can be wiped out and rebuilt by the system.

Open Library > Preferences > System Configuration. Delete all the files in this folder (make a backup if you want). Empty the trash and restart the computer, resetting the PRAM.

If you disabled iCloud keychain, you can reactivate it. Bluetooth and all other services should work now as well.

Good luck! I hope this works for everybody else out there.

I definitely think this is a Mavericks issue.  My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network.  No idea how to resolve this, but here is the workaround I'm posting: 

I've had the 'network drop' issue with my Airport Extreme for the last 2 months.  It reconnects when I pull the ethernet cable and plug it back in.  I've tried downgrading the AE firmware, resetting to factory, etc.  Nothing worked.  I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:

##############

#!/bin/ksh

while true

do

  yup=`ping -c1 -t2 www.google.com|grep from`

  if [[ -n $yup ]]

     then echo "Internet is connected!"

  else

        ifconfig en0 down; ifconfig en0 up

        echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out

  fi

  sleep 5

clear

done

###############

I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!

Good luck!

There is no System Configuration folder in Library > Preference.

It is there staring you in the face.

In the tool bar of finder go to "Go"

Then click on "computer" in the drop down menu

Then click on Macintosh HD

Applications is the first then

LIbrary is just below that click on Library

And scroll down and click on preference (which is just beow preferences pane)

the menu opens and scroll down to "system configuration"

Aha, thanks. I looked at different Library maybe. I didn't know I could access another Library this way. I'm a relatively new mac user .

So Does deleting everything in this folder erase any of my data? If I need to back the files up, can I just back them up in another folder in Documents or something? Or will that cause it to not change anything?

Thanks.

A lot of files will automatically be rebuilt after delting them. That is the purpose the way Ben descibed it. But I am no expert in this. If I was so inclinded to try this I would drag these files into a folder and  then do the rebooting in PRAM. When you put them in another folder it systems configuarion should be empty the way Ben describes it. Having them back up in a seperate folder is insurance.  That way if they do  not rebuild you can restore the  program by dragging it back into systems configuration. If it works the way Ben Busch describes it you can always move them to trash.

Thank you for this advice. Unfortunately, it did not resolve anything on two MacPro Mavericks. They are still unable to detect Airport Extreme network. Oddly, they detect neighbor's networks. MacBook Pros, iPads, and iPhones have no problems on my Airport Extreme network.

Maybe the probem is in AE and not Mavs. Or are there people having problems with other wireless systems?

My problem is on an AE network, using a new rMBP w/Mavericks.  The disconnect occurs after waking from sleep, when syncing keychain in iCloud is on. 

I had no problem with an older MBP w/Mt Lion or a MacPro w/Mt Lion.

This solution looks like worked for me.

It didn't work for me either.

I was having the same issue w/ a brand new MacBook Pro running Mavericks -- it seemed to forget my network upon starting up or coming out of standby. I just spent ~40 min on the phone w/ apple and after the person consulted some other folks, they concluded this is "normal" product behavior when you're operating off the battery. Sure enough, it doesn't seem to be a problem when my macbook is plugged in. They said the prupose is to prevent file corruption in case the computer's battery dies in the middle of transferring files -- seems strange, but that's what they said.

The other thing they recommended was going into System Preferences --> Network --> Advanced, then delete your network and add it back.

Not sure what you were seeing that you described as 'forget my network'.  I'm guessing it means you had to reenter your PW every time, as tho it didn't store it.  If so, that is not what I'm experiencing with a new rMPB w/Mavericks.  When keychain sync is on, and the rMPB awakes from sleep and I try to access the internet, the URL in the browser shows the connection starts but then the blue bar stops and just hangs, never moving all the way across and never reloading the page.

If I then turn off WiFi and turn it back on again, the page will load.  (If I disable keychain syncing, I never see this problem).

I tried deleting the network and adding it back, as suggested.  Doesn't solve the problem.  It's just this rMBP.  Other devices, including an older MBP w/Mt Lion never had this problem.
