Q: Dropping Wi FI Signal

It happens with my MacBook Pro and my Mac Mini. It happens very often with the MacBook and the old AirPort Express. It happens also very often with my MacBook Pro and my Sinus 1024 DSL-Router... It happens sometimes with my MacBook Pro and my new AirPort Express.

And all that in different appartements...

Regards

Sebastian

this is definitly not an issue with Router , interfering WLAN-Signals or else ...

my case:

MB:          10.6.7 (MB-Unibody2008)

Router:     FRITZ!Box Fon WLAN 7113 Annex AFirmware-Version 90.04.82  [g,b, g+b (its all similar behaviour)]

Any WLAN-Device has NO issues on connectifity .. Linux, Windows, Printer even the iphone3GS run flawlessly ..

since upgrading the MB to 10.6.7 i experience the issue of dropping WLAN-connectifity .. Apple then may show me a standing link (icon) , but on the lowlevel it fails ... no TCP/IP connections possible .. no DHCP

DEBUG shows:

#sudo dmesg

en1: 802.11d country code set to 'NL'.

en1: Supported channels 1 2 3 4 5 6 7 8 9 10 11 12 13 36 40 44 48 52 56 60 64 100 104 108 112 116 120 124 128 132 136 140

Auth result for: 00:24:fe:f6:30:34 MAC AUTH succeeded

AirPort: Link Up on en1

AirPort: RSN handshake complete on en1

AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving)

even if the link is up , i get grosse ping replies from my WLAN-Gateway .. sometime over timeout

This is a BAD issue !!! and i suppose it should be taken more seriously by Apple-develpment

.. this is a unix !! not a ms-mug !

Add me to the list - first time Mac purchase - Wireless drops 2-5 times per day on both the home network and the corporate network.  Have an active call with Apple support right now - very disappointing - esp since I purchased a top line 15" MBP with all the bells and whistles - but the wireless will not stay connected - a real pain in my CITRIX virtual desktop environment.  Never has this much trouble with my Windows machines.

Not really impressed as a first time Apple buyer.

What is Apple's return policy?  Can I return this thing?  I do not have much more time to troubleshoot this stuff - I have real work to do - At least with my Windows laptop I could get some real work done - consistently.  Not meaning to bash Apple - but with almost 200K views to this thread - something has to be wrong.

Of course millions are using Wi-Fi on Macs without any issues, and I've had a lot more issues with the Windows laptops I've had to deal with.

That having been said, at least for the US:

Since a couple of weeks our Airport Extreme (2008) is dropping connection every single minute. It happens with MBP, Win7 laptop, iPhone, iPod Touch and other phones, both when using at once and separately (no interfering with each other). LAN is doing fine. All these devices can successfully connect to WiFi elsewhere (at work, at school, hotspots).

Here are some log fragments:

The Airport Extreme is not eligible for warranty, and since it's absolutely impossible to work in such conditions, we opt to buy a Lynksys router. But a device that cost us 170 or something euros has to last longer than 3 years....

I just bought my MBP a week ago and I am constantly loosing connection to my Belkin N router.  It is isolated to my MBP, my PC and PS3 connect fine.  It would be nice if there was a fix for this!

After spending quite a bit of time on the phone with AppleCare about this problem, I finally went to a store to speak with a Genius tech. Of course my MBP worked just fine, incredibly fast even, on their network. He gave me an interesting tidbit regarding older technology routers. I use the standard 2Wire DSL modem/router that comes from AT&T, and apparently the newer AirPort cards are too advanced for these older routers- even when set to WPA2. I don't know if this is true or not, but when I tried his workaround my MBP is working beautifully on the home network. Essentially, I had to buy an AirPort Express (Extreme would also work, but I don't need the extra range), wire it into my current router and then set it up as a separate network. Everything else in the house runs off of the regular 2Wire wifi, but my MBP runs off of the AirPort Express network. Problem solved. I don't know if it is really a software problem or not, but this solution has solved the problem for me.

Mid 2010 MBP 10.6.4 and Linksys WRT120N

Same issues, router worked fine for 6 months then stuck on self-assigned IP, only my macbook, only my network. All other macs/laptops/desktops/smartphones/PCs connect fine.

This among a ton of other issues with this, every web browser (Safari, Chrome, Firefox, Opera, Camino) crashes, kernel panics, already had a hard drive replaced, charger stopped working... nightmare.

I've read and tried everything in these threads, still nothing.

If you can't receive an IP address, then it's a DHCP issue.

If your Linksys provides DHCP service for your network, check its logs for errors and to make sure you haven't exhausted your pool of available IP addresses.

(Many people when configuring their wireless routers set it up to offer five or ten addresses and forget about it, but later when they have multiple phones, a game system or two and other devices like a Wi-Fi equipped TV or Blu-ray player, inadvertently exhaust the pool of available IP addresses their router can provide.)

i would love to see a solution :-) until now nobody who ever experienced this as his own problem ever found a solution nor stable workaround for this issue ..

most obscure advisories ( DHCP, change hardware, old router , bla bla bla ) come from people who are not affected by this just dropping a hint ( even if similiar voodoo has been postet again and again to no avail )

its sad that non but the affected people take this as a serious bug .. and i think most people ( experiencing this ) find an agreement that this s*it definitly started with an "update" ..

to get this on a common stream i think we should all open this incident at the given topic of this Thread to get a unified stance to apple-support ... else the individual is lullabied by a-support one by one ...

There have been many, many people helped by the advice you so easily dismiss, and the advice doesn't come as a "hint" but rather on over 25 years of working with networking and IP protocols.

I get 22Mbps download on my Comcast, and 4.22Mbps upload with an Airport Extreme.

Copying a large file from my file server I get about a megabyte every 2 seconds... So the extreme doesn't appear to help. Maybe I need an Airport Express only?

Going to try to go to the Genius bar tomorrow, have them test it with an extreme.

Is there anybody here which has an affected, unused Notebook and can do a downgrade to Mac OS 10.4 Tiger ? This would be the perfect test. I cannot remind that i had any problems running 10.4 on my Hardware...

I don't think you need to go back as fa as Tiger. 10.5.8 seems to be fine.

So glad I cloned my boot volume before upgrading to SL.

Carbon Copy Cloner.

It looks like 10.6.8 didn't resolve the problem either.

Here's another multi page thread which contains a lo of the same complints:
