mmmmmmhhhhh sorry but I'm a bit confused.  What does it mean "the larger the number"? the distance between signal and noise? in my screen shot the line reguarding these numbers says signal/noise, now just to agree on these terms, your RSSI is the same as signal and noise floor is the same as noise, is it correct?. Then you say that -85 is still noisy (should be less then -90). But your RSSI (signal) is -65 With the values that you have is your connection fine?

As per my environment I really don't know what can cause this noise, in this room there is the tv with the cable-box, two ups, one DVD, small stereo, air conditioner and a neon tube, nothing else. Nevertheless when the mobile-wifi is in the bedroom (like now) it seems the signal is better, now I have a signal/noise of -86/-90.

I really have no idea where the difference is.

The larger the number is, the louder it is.  -88 is a weaker signal than -65.  I think it is unfortunate that these are negative numbers, but that's the standard way to talk about RF signal levels.  Look on wikipedia for "dBm" for the explanation.  You can also look up topics like "receiver sensitivity" to see how RF receivers work.  For amateur radio receivers, we try and make it possible for them to "hear" a signal that is as quiet as -100 or even -110 if at all possible.  That makes them do much better at letting you hear very weak transmissions.

in my screen shot the line reguarding these numbers says signal/noise, now just to agree on these terms, your RSSI is the same as signal and noise floor is the same as noise, is it correct?. Then you say that -85 is still noisy (should be less then -90). But your RSSI (signal) is -65 With the values that you have is your connection fine?

My connection is fine.  I've never had problems with signals coming and going, anywhere, except at the extreme ranges that I would expect.  I also have 4 different radios running around my premises so that I can use WiFi in the house and outside the house, in the yard for my outdoor, AirPlay accessed speaker.  The RSSI at -65 minus the noise floor at -88 is the same as 88-65 or 23dBm of signal level difference.  That makes it strong enough for my computer to "hear" the router/radio over the noise at -88.

As per my environment I really don't know what can cause this noise, in this room there is the tv with the cable-box, two ups, one DVD, small stereo, air conditioner and a neon tube, nothing else. Nevertheless when the mobile-wifi is in the bedroom (like now) it seems the signal is better, now I have a signal/noise of -86/-90.

I really have no idea where the difference is.

So, try unplugging/turning off some of those things, one at a time to see if any are emitting noise that is creating problems for you.  The neon tube would be my first suspect, because it is like a "spark gap" transmitter with a wide range of RF signals likely.  But the motor on the air conditioner as well as the power supply of the cable-box could be other sources.  You could also try using a piece of tin foil as a shield/reflector if something does seem to be creating some RF interference.

Which indicate when the "association" happened, so you can find these, and read before or after to see what happened to cause the association to have to be reestablished, or what broken the association after it was established.

This time I got all the wi-fi logs that you show me. I opened my MBP,  it connected and immediately after disconnected, so I activated the logs as you said. Waited few seconds deactivated wi-fi and then reactivated again just to force a possible reconnection and then closed the log.

I found the lines the you suggested even though the <airportd> number is different.

The log is a little bit longer so I cut only part of it around the first association to my network (capitanMiki) and some more lines before and after the second association.

it seems to me that the system is looping executing the same code, but I don't know why.

These are the lines that I could understand:

at hour 12:15:31.56  my network has been found

at hour 12:15:31.831 is the association with the network capitanMiki

at hour 12:15:31.851 something has changed but I don't know what, anyway this or any subsequent line is causing an halt in the connection because …

at hour 12:15:31.891 the system is searching the network again

all other lines seems to me a loop of the same code

up to …..

at hour 12:22:29.618 the association is made again

I don't know what happens in between, but there are a lot of "changes" of power, DHCP, SSID as if somehow the connection breaks out because there is always something "\changed" and it's not always the same thing that changed.

note the lines at hour 12:22:28.551 "Error configuring antenna diversity (index = -1)." does this means something?

at hour 12:22:30.646 there is "_doAutoJoin: Already associated to “CapitanMiki”. Bailing on auto-join."  is the system trying to associate a net already ***? and if yes, why?

I cannot say more, for sure you understand much more, I hope you can see something helpful. thanks so much

ok, here we are. on the tenth of March the new connection was in place. The cable-tv company here provides also internet. Along the cable there is a splitter, from which two cables gets out, one to the tv and the other to a modem. From this an ethernet cable goes to my airport express. Today are now 18 days with no more problems, no disconnections, no sleeping forever, no slowdown etc. For those that didn't read previous posts here, my  connection to internet was at the beginning through a wi-max router, which supplied wi-fi as well. This setting never worked. I tried to connect that router to an airport express using an ethernet cable, disabling wi-fi and using the wifi on the airport instead. Neither this configuration worked. While my MBP was disconnected, other devices running windows worked perfectly. Probably Apple devices are not compatible with 4G wi-max systems, at least with the one I was using or .... I don't know what other problem could be. End of my story. ciao a tutti.

ok, here we are. on the tenth of March the new connection was in place. The cable-tv company here provides also internet. Along the cable there is a splitter, from which two cables gets out, one to the tv and the other to a modem. From this an ethernet cable goes to my airport express. Today are now 18 days with no more problems, no disconnections, no sleeping forever, no slowdown etc. For those that didn't read previous posts here, my  connection to internet was at the beginning through a wi-max router, which supplied wi-fi as well.

I really think that there are several types of failures like this.  When switching ISPs/equipment at the ISP interface fixes the problem, then it's most likely a DHCP or related configuration issue, on the ISPs side.  It might even be that there are a handful of ISP around the world, creating all of these problems.  We've just never managed to "make a list" of the ISP, Country, routers, etc that might make the commonalities clear.

Sorry but I cannot agree. Yes it could be an interferenze, an ISP problem, a dhcp configuration problem, anything, but if in the same environment I can connect a windows pc and a samsung phone to the same provider using the same router and the same network then for me there is only one explanation: the problem cannot be all over the world but only in one place, apple software. Then you can tell that apple is using more strict protocols which works only with certain hardware, I don't know, but for common users this means only that apple wifi software, starting with lion, is not working. Up to snow leopard I had no problem at all. The worst part of it is that apple tried to fix this problem with two specific updates but they didn't work. And the simple fact that they came out with those two fixes means that lion and mountain lion do have wifi problem and now ios 6.xx as well. I believe there is nothing else to say.

There have been bugs.  If you switched something out, and your Apple product started working, then you seem to have fixed a compatibility problem by upgrading to something working.  It's perfectly possible that Apple was depending on specific behaviors that only their routers provided.  They may have fixed that, or at least have been working on correcting the problems slowly but surely.  In the end, I, and many other people have never had any problems with the ISPs and routers that we've been using.  So, I can only point out, that for me, that means your ISP or router has standards compatibility issues.  Certainly they may have been able to do certain things in a "windows" compatible, or "802.11b" or "802.11b" compatible way.  Without explicit knowledge of what's been going wrong though, all we can do is speculate.  So far, all of the postings here, and the results of those who have fixed their problems, point strongly at compatibility more that just the Apple updates.  Certainly Apple has probably been addressing the "short comings" of the routers/environments that some of their customers have been dealing with.  The "connect after sleep" issue, in particular, is demonstrably a short sighted issue on their side of development.  I have a time-capsule on my network, and that likely was performing the needed work to keep me from having that problem.

Hopefully things will continue to improve as all of the upgrades and fixes occur.  We have 802.11ac compatibility to deal with next.  People buying new hardware with WiFi equipment that supports that standard will likely introduce some interesting new issues.

Okay, so I've read a lot of these posts and fixes for the wifi connection issues with Lion. I would like to add my issues and see if anybody has any ideas for a fix.

I'm running 10.7.5 Lion on  13in MBP 8,2 (2011). When I bought this laptop it came with a Snow Leopard disc, and I loved it. Because I bought it within the 30 day window before Lion came out, I got the Lion upgrade at no cost. Sweet deal.

The problem is after the first year my download speeds began to bog. My wifi connectivity is fine - absolutely no issues of losing connections. It'st just my download speeds. I've tried all the known fixes (that are available to me): reset PRAM, reset SMC, turn off wifi and 'forget' all my connections, changing the DNS, etc. Nothing has worked. I can't modify anything on my wifi router or modem because I actually live in Korea, and there isn't any option to change the channel and I DEFINITELY can't navigate logging into my router to tweak settings... since it's all in Korean. It was hard enough merely setting it up with a password!

One troubleshoot I did do and saw IMMEDIATE results was partition my current HD and install Snow Leopard from my install DVD on that partition and booted it up. A 500 MB download on Lion estimated that it would take 5 hours. The EXACT same file downloaded from the Snow Leopard partition did so within 26 minutes.

I have two options: back it all up and downgrade to Snow Leopard, or upgrade to Mountain Lion. However; it seems Mountain Lion has very similar issues with it's download speeds?

Anybody have recommendations?

This sounds like you have disk space or disk surface problems, or lack of RAM, or something is consuming too many resources and causing the download process to starve for CPU or have problems writing to the disk.

Try and empty your trash and remove junk from downloads etc to free disk space.  Also, see if you have 'curl' or 'wget' installed.  If so, look on the web for instructions on how to use those to "download" something you have a URL for.  Close down all programs and open a Terminal window, and then use one of those apps to download something large to see if it goes faster that way.  If so, it sounds like you might just want to reinstall the OS, or otherwise clean things out.  There might be some other .plist files for safari or whatever browser you are using that could remove a "rogue" plugin or something else consuming CPU.

If you look at the performance meter when the download is going slow, is your machine busy?  Can you do other things on your computer and get quick responses?

Checked it all... downloads cleared, trash cleared, RAM fine, same result. Even backed up & downgraded to Snow Leopard... Only to find the same issue. So I reinstalled Lion on a reformatted machine with no junk. Same issue. Also looked into the iPhoto stream issue - that's not it. I don't even use iCloud thanks to Dropbox.

I just don't get it. While at work my desk PC with Win7 will have a download speed of 10-20 mbps while my MBP will get around 50 kbps. Even taking the ethernet from my work PC to my MBP showed the same results. Using any other download tool doesn't work either. No matter what I do, I can't seem to get above about 75 kbps at best.

Yeah I like my Apple laptop... but the customer care ***** unless you pay more money. And when there's hardware issues they only deal with it if it's not too inconvenient. Doing some research shows that this has been an issue for about 2 years now and the only thing Apple did was release an update that did minimal help.

Even though I like this laptop, my next will definitely be a PC. I can get a lot more computer for a lot less money and not have to worry about these issues.

Oh, and I figured out how to change the channel - didn't work AND it doesn't solve my issues that no matter what router I'm connected to I cannot increase my download speeds.

You are right, it is almost two years with this issue and no solution. It is always "other" fault, devices, provider, carriers and so on. I've already told that it seems to me that apple is not capable any longer to manage radio signals. Plus, this sort of apple-wifi-virus is expanding to ios as well. I have an iphone 5 and hot-spot never worked fine. The other thursday I was attending a conference and a guy close to me said:"hey look in this area there is a free wifi spot" I looked at his samsung galaxy-something and I saw a list of four networks one of which open. So I  took my wonderful iphone, slide the wi-fi switch and voila' ... nothing, nada, niente. I mean, the network list was completely empty, after switching the wifi slide on and off several times , finally one network showed up for few seconds and then disappered, while the samsung continue to show all the networks without any problem.

Maybe the only thing we can do is... forget apple once and for all.

Which iPhone do you have?  The size of the antenna system in an iPhone is considerably smaller than in a larger device (was that a samsung galaxy tablet or larger phone?)  Some of the networks he saw could of been 5ghz radios which are not supported until the iPhone 5.  RF is RF, it's not a piece of wire.  All kinds of things make it hard to get a signal into a device.  Apple's devices and radios and antennas have gotten better.  But, in the end, you might find that there are lots of problems with iPhone wifi "range" in certain environments because of things like the iPhone-4 antenna debacle, which demonstrated that they didn't do the right testing and evaluation of their antenna systems.

As I already wrote above I have an iphone 5 which is capable (in theory) to transmit on the 5GHZ band. The phone of the guy was a small one, but I don't know which model (it was not a tablet).
