Lion WiFi Connection Problem

I note the article you are linking has an illustration of the dropdown box from the wifi icon, showing the WiFi Diagnostic tool. Holding down the Option key does not give me this. I needed to go to HD>System>Library>Core Services>WiFi Diagnostics to find it (these utilities are well hidden). So I have made an alias for it and put it into my Applications folder.

The Signal to Noise ratio (SNR) is actually the difference between the two figures shown. They say that an SNR of more than 25 is ok.

I found most people on my block using channel 1, so I changed to 11.

Why the router thinks I am in Holland, beats me.

Someone earlier on in the posts suggested changing your location. I went into System Preferences > Network and creaed a new location and hooked into that. Its helped - I still disconnect but not as often.

Reboot.

Hope this helps some of you.

I don't know if this will help anyone in relation to the driver's issue, but I have both Lion and SL installed on two partitions on the internal disk of my MBP (details at the bottom of this ost).

Wifi works fine on both systems and interestingly, the firmware version is the same. Does anyone have any idea what the numbers in brackets refer too ??

Hi Everyone, I found this on another thread about Lion and wifi problem...and I of course tried suggestion # 1 and it has helped with stability of airport and connecting....Before when ever I would try to join my network it would jump around in the window and not let me then when I would it would tell me wrong password. Well I did everything described and it totaly helped with everything...I have had no drops at all and my airport signal strength is no longer one bar dipping ..it is full strength.....pages open faster and again from wake up....well here is the post ...Worked for me ..I have to write him and let him know that it was a fix for me and I hope for others.

OK folks, my symptoms were that unless I was in line of sight with my apple time capsule, then no wifi - or it would start but then another device would send it offline. I have sorted it by going into my airport utility screen.

Then going wireless / wireless options.

Choose radio mode and (you may need to press the OPTION button on your keyboard to access this, choose the mode I have chosen below (in my screenshot). You will note this option EXCLUDES the N frequency of networks.

Now finally, all sorted, just reliable internet connection all through my house. Still really annoyed I had to spend this long trying to troubleshoot and scan through forums to get to this. Come on Apple, surely you could just expect it to "just work" like SJ said many years ago ??

Also forum users, how does my score go from 0 to a little higher now that I have sorted this one out ?

Cheers,

I’m facing same problem since August when I bought my macbook pro. I guess I tried all possible tricks: resetting the router, changing firmwares, scrips to renew IP assignment etc. Last week I gave up, I’m fed up with this.

This $15 little device does its job superbly. While native hardware in my $2000 macbook pro is not even close to it. VERY bad Apple!

@ gphonei

I show this:

My problem is that when I wake from sleep, sometimes I'm connected and sometimes I'm not. When I go to the dropdown menu showing the various connections available, my channel is always there, but it doesn't seem to be able to find it. When I click on it, it then connects. Prior to the last iMac WiFi update, I was dropping the signal frequently, and that problem seems to have gone away.

I haven't tried setting it for 802.11 b/g only. My laptop running Snow Leopard and my DVD player which connects to stream movies, have no problems connecting.

I'm using Mountain Lion. This is what I see once I've deleted the System Preferences folder:

Maybe Mountain Lion has some changes (I realize this is a thread for Lion, but I'm having the same issues as you guys and my issues also occured under Lion).

So this looks reasonable. Where did you see the 169.254.X.Y address at?

it is address of the airport express

now, just after I took this screenshot the airport disappered from the airport-utility-screen, it says that it doesn't belong to my network. Maybe it will reappear again later on. Mean time, Internet is still working very well. Infact I'm sending this mail right now.

this is what I've checked

and this is what I get, I don't see any wi-fi logs. I think I have checked what you said.

what am I doing wrong?

While waiting for the new cable-provider-modem I purchased a small mobile wi-fi. I've noticed that if this device is very close to my MBP the signal is around - 33 and -49dbm. If it is in another room, a distance of about 7 meters, the signal goes to -76 dbm and above.

For example, now the mobile-router is far from where I am and this is what the system information tells me:

my network name is "CapitanMiki" and the signal is at -76 and noise is at -85

Now it's close to the MBP (ten cm.) and this is the new situation

as you can see the signal is at -33 and noise is at -86. All the others network around me, but one, have signal and noise with lower numbers then mine.

So far I can tell that when it is close to the computer there are connection-drops; but it is too early to say what happens when it is far because I just discovered this phenomenon. Are these the same numbers that you explained talking about RSSI? And which situation is better, with a signal at -33 or -76? In other words, a lower number means a better signal or is it the opposite?

Hi paul246,

Glad this helped you too. What's really strange is that this DHCP with manual address features isn't even supposed to be supported by Airport routers!! According to this article http://support.apple.com/kb/TA21403?viewlocale=en_US we're not supposed to use it. Now, it did work before I installed Lion so perhaps Lion now does some better checking and disables WiFi when you try to use this option - but it needs to issue a warning or something. Very obscure 'feature'.

Good luck to everyone else - hope you all get this issue fixed - no Internet is no fun!!

I wish I could, when I click on your link and login, here is what I get:

You must be a registered Apple Developer to file bugs via Bug Reporter.
Register at http://developer.apple.com/programs/register/devbugs@apple.com.

So register.

There is (was?) no cost and all you need is an Apple ID.

Alternatively send feedback to:

http://www.apple.com/feedback/macosx.html

And select Bug Report as the feedback type.

from Google

here may be times when using your Mac where you might have suggestions or other feedback for Apple's engineers. Perhaps a system feature could be used in a different manner, or you would like to see a particular window be resizable, or you have noticed a bug where a program does not behave the way you think it should.

Apple has a number of methods to submit feedback, so if you have suggestions you would like to submit there are several ways to do it. Keep in mind that Apple will likely not contact you back, but submissions are reviewed and used to track down and correct problems.

Apple's feedback page

Apple has an online feedback submission form for each of its products, which can be used to submit enhancement requests, bug reports, and other comments in various workflow areas such as design, ease of use, configurability, compatibility, and workflow. This is a very user-friendly page that does not require any special logins, and is used for everything from suggestions to bug reports. If you have an idea, then you can let Apple know about it through these pages.

Apple Support

Apple offers a number of methods for contacting support personally, including phone, chat, e-mail, and in person at an Apple retail store. While you can offer enhancements and other suggestions to the Apple support personnel, they are more geared toward troubleshooting and managing bugs and errors. These options can be found on Apple's Support contact page.

Bug Reporter

If you have a specific problem that you can replicate on both your system and others, then Apple's Bug Reporter is the option to use. This tool requires you to have an Apple ID (for which you can sign up for free), and then then offers a Web application interface for generating problem reports that Apple can investigate. The tool makes it easy to create a new problem, describe it and provide supporting materials (screenshots, log files, etc.), and then track your submissions. This is a more in-depth process but will be a better option for getting involved with Apple's engineers.

I note that, going back a year, to the introduction of Snow Leopard, people were having the same problems.

https://discussions.apple.com/thread/2202507?threadID=2202507&tstart=0

There were two classic solutions at that time:

Go Finder > Your HD > Library > Preferences > SystemConfiguration.

Move the SystemConfiguration folder to your Desktop. (Don't delete it just yet)

Restart.

and

Go into Keychain Access. Deleted all entries for WiFi. Restart AirPort. Re-entered password.
