Q: mac osx 10.9 Mavericks wifi issue

Hi changing the router channel from automatic choice to manual seems to have solved it (for yesterday anyway) keeping my fingers crossed.

I downloaded a piece of software called inSSIDer which shows you all the strengths and channels of nearby wifi users.

You simply choose the one with the highest 'link score'

I also set mine to manual so it didn't pick another one.

Hope this helps

Jack

Hi folks

Sorry re my last post.

After working ok for a day, first thing this morning I couldn't get connected again until I turned the wifi off and then on again.

Lets hope this gets resolved soon because there are so many  'alternative solutions' out there.

As for myself I am going to try changing channels again.

I notice there are no other users on the 5GHZ band but that would mean purchasing another router.

As my Win laptop works ok I don't see why I should.

nah no need for a new router, just get a wifi analyzer app, i used "wifi analyzer" for android and make sure to choose a channel which has a stronger signal and no one uses that channel to prevent interferences and you good to, that's what i did and never xperienced any problems

Yes I used inSIDDer and did just that and it lasted for a day.

I notice up at the higher channels someone with Sky has a really strong signal so I am down at channel 6 at the moment. The inSSIDer software recommends channel 6 for me so I might just move to either 5 or 7.

I suppose it isn't a really big hastle to switch the WIFI off and then on again and no doubt the problem will go away after a while.

Thanks for the help anyway

How cool

found your post re: wifi not reconnecting  up after sleep. Followed the steps and things work the way they should!

the steps were:

1) Delete all WiFi connection preferences.

2) In keychain, delete all references to airport.

3) In Macintosh HD/Library/Preferences delete com.apple.Bluetooth.plist

Deleting the Bluetooth.plist is the newest of the tricks. Of which none of them have worked for me. Deleting the BT.plist only turns on Bluetooth after reboot and I get no response when setting up WiFi. When I try it shows all my networks and allows me to select one, but goes no further. Have tried this one several times and hope that trying one more time would work. Nope.

Thank

I am hoping Apple are working on the problem and will come up with an update soon.

Meantime I just turn off and then turn on wifi and that works.

Cheers

I have a 15" pro I purchased in January, and I have found rebooting fixes the wireless when it is wonky.  And by wonky I mean it either won't connect to my wifi at all, or it connects and everything is godawful slow  (Apple remote desktop to another machine in the network takes a measurable amount of time to refresh the screen).  Reboot, and it is back to normal. 

Can anyone corroborate my solution?

So far it has only been a minor nuisance for me because my laptop is just used as a dumb terminal to access my real desktop, but I could see this as a real deal breaker for someone who wanted a working high dollar laptop.

Welcome to Apple Discussions

You're using that MBP in about the the worst possible configuration - no wonder you're not happy.

As a "dumb terminal" it should be wired to the LAN... (from the Remote Desktop manual pg 29: Network connection using Ethernet (recommended), IP over FireWire, or AirPort)

re: themachead

I actually do use ethernet when I am in my office since I am in a fixed place.  However, I often need to work onsite at my customer's offices, as well as sometimes sitting in the living room to keep half an eye on my kids.  Not to mention setting up shop for an afternoon at a coffee shop or the library closest to my house.  When the wifi works, it is great.  I think your comments are unfounded. 

The problem is that the wifi is not working as well as my late 2007 Macbook that this machine replaced.  Nor does it work as well as the mid 2009 mac mini my wife uses.  The fact that rebooting fixes everything tells me it has probably has something to do with drivers and wakeup (as others are suggesting).  I wasted about an hour reading all the posts I could find, and no one has said reboot fixed it for them.  I offered it up because it may be the kind of clue that will help apple fix this problem.  Driver bugs are hard, as many clues as they can get will be helpful - although who knows if any developers lurk in these forums.

This sort of problem has happened before on my mid 2007 macbook.  I think it was when snow leopard came out.  It seems like they eventually fixed it.  I remember at that time making a new location fixed it for me.  This time that did not.  And since this is a brand new machine with the only software installed so far being VNC, chrome and Microsoft remote desktop, it seems likely this is an OS issue.  (I deliberately install as little software as possible on my dumb terminal to keep it as close to stock as possible).

Hi

I am having the same problem with a new machine. (see my earlier posts)

As a final effort I have completely deleted my hard drive and reinstalled Maverick again with minimal software.

It worked fine for a few hours until I restarted it a few times and back came the old problem.

As no one at Apple seem to be able to fix it I am considering returning it to the shop while I am still able.

This is my first Apple Mac and I am very dissapointed.

My "comments" came from the manual - that for optimal performance Ethernet is recommended, by Apple.

That's not to deny that you might have legitimate WiFi issues - as you can read plenty have. I think that if it were only one issue there'd be one "surefire" fix, or workaround, that would cure the problems - which are varied.

The thing you can't control, verify or correct are access from places where you can not eliminate the router or its settings as a part of your problem.

Don't let that window pass by.

I'm curious. Have you made any changes to your router set up? Is the problem "universal" does it happen everywhere? Did you take it to an Apple Store or Certified Service Center - did the problem occur there?

For those who continute to struggle with getting a fix has anybody tried shutting off their wifi and and adding a USB wireless adapter like the USB Edimax  EW7811 Un. It only goes to 150 Mbs but they also have the Edimax 77UT22UTN which is 300 Mbs. They are both compatible with a/b/g/n. And they both have drivers that are Mavs supported are WAN protected and have 64/128 WEP, WPA and WPA2  encription and WPS.  I gotta wonder if this would be an interim fix for those with continues problems.

See http://www.edimax.us/html/english/frames/b-download.htm for the drivers.

Anybody thoughts about this idea

There are different people with different problems. this was the most dissappointing bit of realization, at least for me, because it means less of a chance the issues (all of them) will be addressed.

For me:

* One Wifi router configured: WPA2-AES

* Laptops (both Mac and non-Mac) work OK on Wifi. (No issues!)

* I got an iPhone 4 it failed to maintain Wifi connectivity.

-- Must turn Wifi OFF then on again for it work for a short time, then rinse repeat!

-- With neighbor's Wifi router it works fine (been using it with their router)

-- With each iOS update I hoped the issue would be fixed. No luck there.

* MPB update to Mavericks it too developed same issue as the iPhone.

-- Fails to maintain connectivity with Wifi.

-- Must turn Wifi OFF then on again for it to work for a short time, then rinse repeat!

-- Found a better workaround with ping tool: https://discussions.apple.com/message/24119041#24119041 (also posted in this thread)

-- MBP works fine with neighbor's Wifi router

Based on my experience with my devices (iPhone4 and MBP) I can say (very confidentaly) that, at least, my problem, has to do with how Apple's software deals with AES in their Wifi stack.
