This might solve your issue. Had been struggling for months. Nothing else worked. This did! Thanks a ton, bro! However, knowing that the keychain and old WiFi connection data from the old Mac had transferred over to the new Mac, and knowing that something might've gone screwy with the network information, I decided to do the following: Open System Preferences, and click on Network. Then select 'Join Other Network Click connect, and the connection will fail Michael — 6 years ago.
But that means every time I go anywhere with a wifi network I will have to manually add the name not just the password if I want to revisit the place and have it auto-connect. This is ridiculous and Apple should not be releasing an operating system that fails on something this basic. Oh no! This OSX update seems to have other knock on effects. What has happened to Apple?!!! Does anyone know of a fix? This seems not to be a time-out problem, as it just occured while I was actually working on the iMac probably not really using the network connection though.
I can also tell from the Time Machine backups that the connection works fine for a couple of hours, even throughout the night, but then at some point just stops. Any idea, anyone? However, again, thanks OSXDaily for fixing my main issue, which was terribly slow speed. I just bought a used iMac Core 2 Duo with Software update asked me if it should upgrade to Now, even though the iMac does connect to my home wireless network I cannot get through to the internet.
This problem started for me as soon as I updated to Lion upon its release. Instantly my wireless connection slowed down to almost the days of the dial up days. First thing I did was reset my router and upon doing so my problem was solved. It is faster than it ever was before. Another option I have been told works, is to completely rename the base station after you reset it, but not your network name if a simple reset does not work for you.
Finally, after days of problems with the wifi and getting the connection back on your fix worked! However internet was deadslow! Placed a call to Apple and they had me do the following:. Repair Disk Permissions using Disk Utility 2. Delete the following plist files from system configuration folder on your computer: I have tried this but there seems to be something missing: I have done all the steps above, but my connection still drops when the computer is inactive.
Everything worked fine until I updated my computer over the weekend. I tried every thing suggested so far to no avail. So I used Energy Saver Prefs to never sleep and the problem was avoided unsatisfactorily. Two days ago I applied the brand new Time Capsule firmware update via Airport Utility and turned sleep back on — working a-okay ever since!
No it did not work for me. Complete Apple convert and really disappointed with the lack of resolution by apple to this problem. Me too. Doubt I will buy an Apple product again. Temptd to ask for a refund on the iMac I bought last year.
The older iMac worked much better before it broke down. Apple knows we are all having problems and is doing nothing. Probably too busy deciding on new colour for next iPhone or something. I can connect to some networks, but not others, although not reliably. The problem disappears for hours, then suddenly returns. Reseting the router seems to work, but I can only do this at home.
So far so good! I never have problems at home or at my university. What I do though is run a torrent and set the transfer speed to 1. Wifi never dropped again. I have terrible issues after upgrading from Much appreciated. Seems to be very MAC specific, tried all the above, Home hub on channel 6, reset keychains, deleted keychains, locations, profiles, you name it!!!!! Definitely worse since upgrading to bloody iCloud! I had the same problems with joy connection dropping all 10 minutes or so… I tried all, but nothing worked for me.
OS X Lion: Serious Wi-Fi Disconnect Problems for Macs, And Solutions? | iLounge Backstage
I have a TP-Link router and all other apple products worked really well on the n-wifi iPhone, iPad, macbook , but not the iMac! Called into Apple Support for mid Air with timeout issues. They had me remove all existing networks from network settings. We then reset the power management by turning off the computer; while powered off, held down Ctrl-Shift-Opt and Power for a few seconds, then releasing them simultaneously — nothing should visibly happen, except I noticed that the LED on the mag safe changed colors briefly. I waited then for 30 seconds or so, and powered on.
Went into network settings, reentered network info, and Voila…seems to work so far…. Thank you for this tip!!!! I been having so much trouble with drop or unable to connect wifi with my lap top. I could not understand until I looked into it. Now that I have read this site and done all of the steps above and prior links to this page. I was able to login I hope this dose fix this problem for good!! Thank you very much for taking your time to help us. Solution work for me. SO FAR!! I used a mixture of the advice from here.
I bought a new iMac a couple of weeks ago. Wifi kept dropping out every 10mins or so. This is what I did: Would be much appreciated. Searched Apple support site tonite. Did that. Connected AOK. Put Mac to sleep, woke it up, instant connection, Did this a few times, all is well. Not complaining at all! I know you posted this ages ago, but I am desperate for a solution — did you ever find one?
I have the same problem. It certainly do the trick. Tried and it works like a charm, thanks! I guess it could be because of the old network profile conflicts by migrating to a new OS X Lion. And now, none of our devices can connect: PC, iPhone, iPod Touch. What have we done wrong? I was using WEP security. Changing to WPA2 fixed the problem immediately. We have 2 iMacs mid and both have this problem of dropping connections. Since they are not really portable we have them wired up to the router, although we have wireless available too.
Both have the latest firmware and software updates, running Sometimes switching wi-fi on and off again helps, but what a pain. I installed my new time capsule and since, the only way I can get online is through an ethernet connection. I want to scream or cry…or both. After going round and round in circles, wasting time acheiving nothing your advice worked a treat. This was happening, intermittently but regularly, on three different older but still recent Macs connected to our home network that had been updated in recent months from Leopard to Lion.
My MacBook Air that came with Lion installed seemed not to be affected, nor were our iPhones and iPads connected to the home net. But it was tricky, because sometimes pages are slow to download for other reasons, even on the MBA. But I began to assume it was related to the upgrade to Lion on the older machines. Googling that is what led me to your solution. Seems that the various other suggested solutions such as deleting the Safari cache, switching to other DNS servers, etc. Presumably Apple now has also figured all this out and will solve it in a future Lion update.
In case this helps with the ultimate fix, one work-around I discovered and it did work before I tried your more elegant and, obviously, more settled solution, was to add the IP address That seemed to solve the problem as well but, and while I am no expert, could that setting have caused problems if the Mac was moved to another network without deleting that entry? I had this problem too and solved it by doing a clean install of Lion. After that it was gone. This is of course quite a drastic method since it takes time to reinstall lion and all your software. So what could have prevented my mac from being able to connect fast enough?
Apps that consume processor cycles. It might prevent airport from being able to reconnect quickly enough before it times out. Mobile Config profiles. Another thought I had was that I had a mobile config It used TTLS to connect to the corporate network. This profile might have gotten in the way. Routers with hardware acceleration might also be a problem. As soon as I activate that my wifi connection keeps dropping. Go into the wireless settings of the modem http: Finally got this solved!
I spent an hour and 45 minutes on the phone with various people at u-verse support to convince them to give me an alternate address, and the Tier II tech finally admitted it was a known issue with them and OSX. This worked!! I have Late Macbook with lion. Updated everything and spent hours trying to fix this. This simple solution worked!!! Thank you!! I have iMac and iPad2, the wifi worked flawlessly with both of them so I was getting very frustrated. This worked perfecty as described. My netgear router got unplugged … and when I turned the router back on, I had lost my two macbook connections a new macbook air and a really old macbook.
I have turned the wifi on in each of them. Any tips on what I should try next? This solution did not work. I have had no lucy for the last couple of hours and just tried your solution and am u and running, hopefully it stays that way. After hibernating and sleep mode, I lose my bluetooth connection. I connected a usb mouse and it can wake the computer but there is no way to reconnect the bluetooth or access the internet without rebooting.
Look for Network and then click AirPort below it. This will take a second as your Mac loads all the wifi networks available. Find your network and look for your Channel number. Look through the other networks and see what channel they are on. If you see a lot of other networks using the same channel as your router then this may be your problem. Look for a channel number in the range of 1 to 11 not being used, or the number used least. Log into your router. Go to your wifi settings, this will vary for all routers, but on my D-Link it was under manual wireless wifi setup.
Change the wireless channel to the channel you chose in step 4 I set my channel to 3 as most of my neighborhood use rest of the channels and turn off Auto Channel Scan if that is a setting on your router. Also i set my wifi to I reset the channel to 2 on the main Airport and, hey presto, WiFi is now stable. Many thanks! Thanks Jazman. Changing channels seems to have cured my wifi dropping problem.
The problem still has to do with Lion OS. My router is an Airport Extreme, and I have a number of devices connecting to it. That includes an old iMac running The only device that drops the wifi connection is the new iMac. Here comes the interesting part. While the old iMac detects only one additional router in the neighborhood, the new iMac detects six of them, at least half of them using channel 11, which is the channel my own Airport was using.
It seems Lion OS has a lower threshold for detection sounds good , which causes a lot of noise. The old SnowLeopard OS is not as good in detecting wifi signals, and that keeps things cleaner. This worked! I was ready to throw my MacBookAir out the window!! It would totally freeze after websites etc…. I tried this, but the numbers on the left never repopulate. I have no idea what that means nor where to find that information.
Mac OS X Lion/Mountain Lion - Could not join network/timeout
No good. I created a new network, waited until the numbers chad repopulated, but in spite of a stable modern connection and connection via ehernet being possible, my MacBook Pro will not recognise either my existing wireless setup or the new one. I have replaced all the cables, the modem, the splitter and reloaded the software.
My next move is to replace the computer. All other devices continue to work flawlessly. The older iMac has The only way to reconnect was to turn off the wireless setting, and then turn it back on. I spent 3 hours on the phone with Apple support, going through literally 3 levels of their tech assistance trying everything and nothing worked. Finally I was transferred to a supervisor who suggested I trash my system configuration folder and reboot. That seemed to fix the problem. The guy was puzzled as to why a new, just out of the box machine would have a corrupted folder, but it did seem to stabilize the wi-fi connectivity for me.
This totally worked! Thanks so much! I work from home through a VPN and having it restart every 10 minutes was making my day miserable! Sadly this has not fixed my problem.
Our 2 iPhones and our iPad are holding the connection without any interruption at all. The iMac holds it pretty well but will not pick up the connection again after sleep or shutdown. I followed the instructions above to the letter — twice now. Sorry to post again but clearly the solution revolves around the significant differences between iPhone and iPad versus Mac computers or laptops.
Almost everyone is fine with the smaller devices but not with the bigger ones. Thinking now of tethering my Time Capsule to the router to see if a signal from that is better liked by the Mac. Been on the phone with Apple for a couple of hours with the Lion dropping wireless issue. Went to a senior advisor. Apple is aware of this issue and engineers are working the problem. No estimate for the update but one is coming. So much for the hype about Apple.
If I ever had doubts I am now convinced — apple is not the answer — I will be sticking with my windows machines.
OS X Mountain Lion and later
Thank you, thank you!!! Finally, my MBP is able to connect to wifi after upgrade to Lion!!! You are a God-sent! Thanks again! I came across the answer in the comments on a past Lion wi-fi issue article here on OSXDaily, and it resolved the troubles for […]. Wont seem to hold onto the wireless connection Originally Posted by the phantom pieman Lion Try this. I have a iMac already came with Lion and up until last week airport worked perfectly, but I was having problems with the internet provider.
Their technician came over and changed my modem which was connected to a router I had installed and configured. The only computer that keeps dropping the connection is my iMac. Does anyone have any other suggestions? Connection drops every 10 minutes, no kidding. This is driving me insane. I do travel i lot, and use multiple routers, like one at school, at my moms house, dads house, etc.
What do you guys think? I have tried all these fixes and none of them work. Open meaning no password. My wifi was quitting every couple of minutes. There are no numbers on the left side to repopulate. Have tried every possible fix and nothing has worked. Any suggestions? This all started when we changed internet service provider. Till then I had no problems. Thanks for the post!
How to troubleshoot Wi-Fi connectivity
For me on Lion it was a firewall issue seems to be buggy. I enabled the firewall and disabled it. I tried removing all airport alf plist files and deleting the connections with no fix in site. Delete all airport. Thank you! Thank you again! Oh Man! I thought it worked but nope…still having the problem of dropping wifi… never happened before but seems to have happened after Lion install. Also Pandora is going all crazy on me too since the Lion install.
So not sure if it was really just the SMC or the combination of the two. Fingers crossed. The first fix that worked! Thank you so much! Still need to check stability, but at least was able to connect instantly. I was in a flying rage all night because i did everything 5 times through and kept getting the same results! Thank you so much!! Great Fix. Constantly dropped wifi — spent more time looking for a signal than holding it. You guys rock. No, I tried all of these things and nothing worked at all. The problem seemed to start when I got an iPad.
Could that be the issue? Mac OS X Just did these steps and did the trick! Not exactly fast, but so much better. Wow — thanks — I was going crazy — I had to quit telecommuting till I found your fix! This works amazingly well! Thanks so much for sorting this out. You can also supplement this with the following procedure RC wrote about it above: Otherwise you end up like me, with a major work deadline on Monday, and my documents all stuck in Google Docs and being shared with colleagues in Dropbox, Basecamp, etc… and me, the foolish Mac advocate, unable to access anything.
While the cretins in Cupertino watch their stock value and smoke crack or whatever it is they do to avoid dealing with the titanic bugs in Lion. Needless to say, my next laptop will most definitely NOT be a Mac — and I think my problems have put off my colleagues, too! Did that yesterday and problem solved!! Tried everything and suddenly… Thanks Apple, better late than never, I guess…. Thanks so much for this fix. This problem was driving me nuts. I went from 3mbps to So simple!
I recently purchased a macbook pro and have had nothing but problems with it. It is a complete piece of garbage. I am not a recycled PC user, I have used Mac for many years. I bought this thing with the quad core intel crapset and its slower than my single core G5. A stinkin PC might be faster. I could understand if it was I that caused the problems but after reading many forums, it is clear that I am not the only one. I can watch Netflix but all the programs that I bought over the years are worthless.
I was a staunch supporter of mac, now I do my damnedest to talk people out of it. My Samsung Galaxy Tab running version 2. More than once i have had to stop myself from heaving it out the front door. I am so very disappointed. Thanks guys. I just got this new imac and suddenly had this incredible stupid problem. Updated and tried everything.
