Q: Lion WiFi Connection Problem

Thannks Pertz. I am sorry i just do not know where this avast is. Could you please be kind to give the route through which one can get to avast. I am having a deep problem with my Wi-Fi since yesterday and this my first time to get such a problem since i migrated to Lion just a month ago. Chris

I really feel apple did not do their work on this one...the Wi Fi and Lion OS X. I was running fine with my internet on Leopard but when i migrated to Lion problems began. I cannot connect to the Wi-Fi. This is what i get everytime i try to get connected: "Wi-Fi has the self-assigned IP address 169.254.215.21 and will not be able to connect to the Internet." Surely, it does not connect even though sometimes it shows itself to be connected. I tried so many tricks from diagonistics, assist me, deleting the network and re-joining but nothing is working. All other guys on windows around me have no problem with the net.

Once again, here's a simple workaround that worked for me and at least 3 other people with the drop-out problem:

Disabled n-mode on my router, rock stable connection ever since.

So again for everyone with the "drop-out"-problem:

1. Go to your router/Airport configuration,
2. search for "Wireless Settings", change "Radio Mode" or "Wireless Network Mode" to
3. "802.11b/g only" or "802.11G only" or "2.4GHz Only" or "G Only".

No more dropouts for me.

If you can't find this setting, post the model of your router and I will try to direct you there, it's a really easy workaround that takes 5 minutes to try out.

If it works you'll only sacrifice some wireless speed for stability until it's fixed by Apple.

-------------------------------------------------------------------------

Here's what my original problem looked like:

2008 macbook, worked fine with SL, on Lion the WiFi symbol showed a connection, but every few minutes the internet just "stopped".

All other devices (iphone, android phone, win laptop, ps3) worked just fine, and had a steady connection, while the macbook was out.

diagnosed this by pinging google on all devices, and every device kept a stable connection, only the macbook was timing out.

Since several people posted that it "worked on their 2year-old router, but not the new one" I tried to make my new "N"-router older, or simply slower. and it worked.

Things I tried that didn't work (again, for me):

setting fixed DNS-server, setting the router to "N"-mode only, setting router to fixed channel.

---------------------------------------------------------------------------

So once again, please try this simple workaround and post if it worked.

"It is not up to Apple to Address your network issue... You need to address it."

"Complete rubbish. People buy computers, follow the set-up instructions in the manuals and expect them to work. My system was working fine until a few weeks ago when I upgraded to 10.7.3. Whatever is wrong is clearly their fault, not mine, and they need to fix it. They broke it."

Agree with this criticism of Carlo TD. There is ample evidence that this is a software problem and a Lion problem. If you read the entire thread I do not see how you could conclude otherwise - Boot Camp+Windows 7 SOLVES THE PROBLEM on the same hardware (same computer and same router).

As a OEM of complete computer systems it is the clear responsibility of that manufacturer to produce a wireless system that is compatible with the latest networking standards 802.11, as well as backwards compatability for many prior versions of that spec. If done properly this would insure compatability on 99.9%+ of routers. Apple clearly have not achieved this.

I'm stunned at how much of an Apple fan boy statement the first one above it. You lose serious credibility all around spouting such rubbish. I'm an Apple fan but in no way a fanboy. I have been super critical of my MBA to anyone who asks or anyone whom I can share my opinions with. Might only be doing a tiny bit of "damage" but Apple deserve it for this mess.

Second the "nice post" comment to Tony850 for that big list. Tried most of them myself...

I have tried all of these, and unfortunately, they don't work. Downgrading to 10.6 doesn't help.

I think the issue is the EFI firmware update Apple released recently. All of the symptoms you mentioned happen to me, seemingly randomly. The ONLY temporary fix I've figured out is to shutdown the computer (uncheck restore windows), reset the SMC (resetting PRAM doesn't help), and then turn it back on. Then it works until it doesn't again. But until you reset the SMC, every other fix doesn't work, even if you downgrade to 10.6, or 10.7 (from 10.7.3), etc. I've even tried wiping the whole drive and reformatting it to make sure that clean installs don't work.

I sure hope Apple comes up with a fix soon. I can't keep doing this everytime I need to use the internet, not only will it drive me crazy, it's wasting a lot of my time. I'm really bummed about this particular messup on Apple's part.

Hi

Lion and wifi dont functionne correctly

I have made all the things recommanded:

Upgrade in X.7.3 on apple page

in routeur norm G

in Mac HD library preferences Rename the system configuration, restart

ETC and wifi unstable

My mac is old three weeks, i am desperate.

I've been having this problem in my iMAC since the Lion Upgrade as well. Turns out, my friend next door, who has an iMAC is also experiencing the problem with the wifi connection.

We both will suddenly lose the connection, but only on our iMACS. Ipads, Ipods, Macbook and Ibook work fine.

I spoke at length with an Applecare Tech. We tried various things, but they did not work. He even had me upgrade my Airport Utility to 5.6 which made things "BETTER" but the problem still remains.

It seems that when in sleep mode, it is at the very worst. But I can be reading an email and then go to reply to it, and suddenly, it's hanging and I get that "question mark" in the Wifi telling me that there is no network connection.

I called Applecare back and was told that they are aware of this problem and that the next update for Lion, which will be 10.7.4 will fix the problem and that I should keep checking for the update.

Let's hope that is the answer.

On a side note, he mentioned that my Airport Express is old (2006) but my friend has a fairly new one, 2 years old. She's having the same WiFi problems.

APPLE...please get the update to us. And when you release Mountain Lion, make sure that this doesn't happen again?? *I couldn't resist*.

This is the same situation I was having.  It was losing connection on waking from sleep, but it was also randomly losing connection all the time.   There are plenty of people in the thread having both issues. Someone was making a big deal earlier in the thread about it being 2 seperate problems, but it seems pretty clear they likely have the same cause.  It seems some people also start with the wake from sleep issue, and graduate to the problem occuring all the time.

Someone was also commenting that this thread is basically the same people posting over and over again as well.  I get email notifications when the thread is replied to, as most of us do, and I can assure you there are new people posting to this thread every day.  Yes, there are some active posters but it's definitely not a case of the same people making most of the posts.

Yes, this seems to be a widespread problem, which has gotten progressively worse for so many people!

I'm just hoping that the update for Lion OS (the upcoming 10.7.4 update) is released soon. I check my software updates daily now, hoping to see it there as the Applecare Tech said that that will solve the problem.

Fingers crossed!!

Yeah well if you think it can't get any worse...Think again!!! I have been having the dropped signal stalling browser ever since updating to lion...after all of that ..then my time capsule was not working and I kept getting a window that it had to be erased because there was no more room....okay I did that and 1 day later it died!!!!!! second tragedy after that I no longer have any signal on my airport icon..I click on it and it is grayed out with the words no hardware installed........Are you F...ing kidding me!!!! So I had to do a partition and put all of my original discs that came with my computer in and now am able to type this from the original 10.5.2....and guess what there is no problem with the hardware because my signal strength on the airport is full tilt. Lion was Apples biggest mistake and they sent everyone down this road of confusion and frustration. I am done with apple products and will never buy another just by the way they have treated this disgusting fiasco they call an UPDATE! The sad thing is the only reason I updated was because I purchased a new 4s phone and in order for it to work with everything u needed to also upgrade to Lion......and now I can not even upgrade even if they have a fix because that part of my partition can not connect to the internet to be able to apply it to lion. Really Really bad business decisions...If Steve Jobs were alive he would've gotten rid of every fool who worked on Lion. God rest his soul he was the glue that held the company together and now it's going straight to the toilet. Their reputation was built on people like myself praising them for 15 years and now it will be taken down the same way.

I'm also having the Lion WiFi problem.  Rather than driving myself crazy to continue seething in anger, could I just re-install Snow leapard?  If I do that, when Lion is fixed, can I just download the new Lion release without having to pay again?

I am a new iMac user so am not as familair with Apple. products or policies.

Alex Reiler,

Your wi-fi dongle looks like the D-Link DWA-131. If so, how did you get it to work as there doesn't appear to be any drivers for Lion.

+1 to this wifi issue. Can not connect to an airport express, however I did manage to set it up w/ my iPhone twice... but the MBP still timesout and wont connect to the wireless signal. Not impressed. :-\

Downgrading to Snow Leopard is possible and will 100% fix your wi-fi conection. There are 2 ways to downgrade to the os 1st one trough an old Snow Leopard Time Machine back-up. 2nd insert the Snow Leopard disc then turn the Mac on and follow instuctions on dics. Then erase your hard drive then you can start with installing your Snow Leopard disc. However if your machine had Lion as original os you can't downgrade to Snow Leopard (Lion is a better version) Apple is working on a fix for this issue and will be out soon*. You don't have to pay agian to upgrade to Lion from Snow Leopard. Guys Mountian Lion is coming this summer and hopefully Apple test their software better befoure luaching it. I love Apple and i downgraded becouse of a frustrating issue i expect Apple to fix it.

* Soon means someday in the future

No it won't, neccessarily. My problem STARTED in Snow Leopard, and continued into Lion. Mine's been going on for almost 2 years, so it must be a major issue for them. A fix is coming, but downgrading isn't neccessarily it.

Might work, but then again, might not.

Cheers,

Cameron
