Mac os lion internet disconnect

OS X Lion and earlier

Step 1: Open the Apple menu and then click on System Preferences. Step 5: Click on anything inside the Preferred Networks panel. Step 8: Click on the Locations pull-down and then click on Edit Locations. That should be it. Jignesh Padhiyar. Sponsored Links. THAT worked for me — what a release! I had a few issues initially but I rebooted and it cleared it up.

What is your hardware? I have a late MacBook and I took it to the genius bar and the guy told me to buy a new airport card. This is something with lion. Last thing. I reset the smc that worked occasionally to restor the wifi connection but I lose it again upon reboot.

Please notify if you find a fix for this. I actually was having WiFi problems just before upgrading to Lion. Like a couple of weeks. Had to zero out a plist in the library. My transition to Lion seems to be good now. Most of my WiFi usage is on public WiFi so this might take sometime to verify.

I was trying everything and nothing works but when I turn off Adium wifi connection is working perfect. Are You using Adium? Somebody suggested turning off bluetooth in network connections. Not had any issue after making this inactive. But the rest of Lion sure runs sweet on the old girl. Thanks for the suggestion, guys!

Trash the SystemConfiguration folder inside of Preferences in Library at the hard drive level, reboot, set the Network parameters again turn wifi on, add new location name, select a network, etc. Been there, done that. Once before I talked to Apple and once afterward. The glimmer of hope: The alternative appears to be, according to Apple rep I spoke with, reformatting the hard drive and re-installing Snow Leopard from the DVD that came with your computer.

Dude, U have no idea how much pain this thing brought to my life! Your solution was the only one that worked for me after several days looking for it in forums, and have no words to thank u ; Saludos from Colombia. If a router such as airport express run under channel 11 I continuously get the same timeout error. Also having trouble with Wifi after waking up the computer. The weirdest part is that it seems to only be web browsers that are affected.

So that, to me, is the crazy part. None of the browsers work, but I clearly do have a network connection. Of course, turning the wifi off, then back on again fixes everything, but having to do that every time I wake up my computer is a bit of a pain…. Steve we need u back.. Zap the pram. That fixes it.

On start-up hold down the Opt-Cmd-P-R buttons for 2 cycles of the startup chime. Definitely just fixed mine. Tried all fixes here and on other websites without success. If the computer idles and goes into Energy Saver sleep then no problem with WiFi. Avoid using the Power button to initiate sleep. Hi, I had the exact same symptoms as you and solved my issue by using the previous suggestion of deleting the existing locations and adding a new one. I keep on following the news and with the release of every developer release of Mac OS X With every release of Mac OS X My connection keeps on dropping.

So, I was hoping Lion would include updated Airport drivers or some other fixes which would fix my connection problems. My access point is a Linksys WAP All of these connection troubles seem like compatibilty problems between Airport and Linksys, so I hoped the compatibility with Apples own wireless devices would be perfect. So, I thought: Drivers will be updated, parts of the operating system will be rewritten, so I think Lion will solve my problems.

Apple makes great products and everythings works perfect, but the only problem with Apples products is the dropping connections. Why is it so difficult for Apple to maintain a connection? The log files always say: Why should inactivity be a reason to drop the connection?

Just drop the connection when close my Mac or when I reboot or shut it down, but in all other cases, just keep that connection alive.

I stay at the same website, but the content of that page is constantly being refreshed as I move the map and zoom in and out. With every move and with every zoom new content need to be downloaded, so there should be activity all of the time, but after a few minutes the connection just drops.

Why is it so difficult for Apple to maintain a wireless connection? How is this possible? Windows never drops wireless connections and even those amateuristic Linux-distributions never drop wireless connections. I upgraded to OS X Lion. Right after the upgrade I had to enter my wifi password.

It is a 2WIRE router.

But after some idle time the computer goes to sleep mode. I tried rebooting. I tried deleting and readding the wifi network via settings. After a reboot, the system connects to the wifi network. Now I am at another location where I have a Linksys router. I am having no issues with the MBP losing connectivity with the wifi. It goes to sleep and upon waking it can find the network. Every time. This is the one that worked. Thanks, man. Turning airport off and on fixes the problem.

Fix for a Mac Disconnecting from Wi-Fi After Sleep Wake

Like one of the correspondents on this site my wifi will simply not turn on, it was working after the lion install but after a restart it was off and clicking on the turn wifi on has no effect either in the header on in network preferences, I have tried the various suggestions offered here and elsewhere with no effect. Ethernet works fine but Looks like I will have to go back to Snow Leopard to get my wi fi back. Can see network, but get message that there is a network issue. Two other computers, and two iPhones, and one iPad connect fine, with same settings.

New MacBook air having issues. Wondering if I should send this sweet computer back? Wifi works on my iPhone which I am using now but will not work now on my MacBook. It worked for a little bit when I first intalled Lion but now I have tried everything on here that I understand but nothing. Same problem here in Brazil. I have just bought a MacBook Pro and the wifi connection sometimes works. I went to the store where I bought it and the problem was not resolved. They said that it was a hardware problem, and exchanged the MacBook Pro for another one, which has the same problem.

The question is: How Apple can sell expensive products with a ridiculous problem like that? It would be hilarious if it was not sad! I feel totaly fooled by Apple! I now log into to a connected WIFI state. This is also resolved. I encounter similar problem which cannot get the IP address even it can connect. The big question is: Why Apple does not fix the problem? The great answer is: Apple does not care because there are fools like us that still buying their products. I usually wait until the first update to upgrade to a new OS, but did not have the choice it was coming with my new MacBook Air!

Mine would lose connection after sleep mode or reboots. It was fixed after i went to advanced settings and removed all my networks, turned off wifi and turned back on, and then re-added my networks. If you are suffering from loss of internet connectivity after you wake from a sleep then remove any CD or DVD from your drive or remove any external drives. Problem gone!! Have tried restarting router, tried removing and re-adding wifi, setting it as top preference etc, no luck yet.

Thanks, you really helped. I was getting 5 Bars of signal strength, the router said I was connected, but no net. I went to Network, then to Location, and Edit Locations, then deleted them all and reconnected to the same network name and voila wa-laa. I previously posted deleting the SystemConfiguration folder resoled me problem. It did not, as the problem soon returned. My final solution was to look at my Keychain Access, where there were multiple entries for the same wireless network I was connecting to.

Removing the duplicates resolved my issue and this has not disconnected since for about a week on DHCP. Spent approx. Also suggested to try a different router to the Belkin I am using, suggested a Netgear.

Fix for a Mac Disconnecting from Wi-Fi After Sleep Wake

Other fixes […]. Here are Some Wireless Troubleshooting Solutionshttp: I too started having dropped wi-fi connection after I upgraded to Lion on my iMac bought in early I had no issues whatsoever when I was using Snow Leopard, but once I upgraded to Lion, the connection would drop so frequently about times every hour that it became unusable. I tried all tricked in this article but nothing worked. The only way was to turn off and then turn on wifi on my iMac from the menubar. Like many I have issues with Wi Fi losing connection. Lion Connecting via Ethernet [in my case over the house Power Supply cables] to my Belkin N1 Vision Router does not have any similar issues.

Sadly everything else offered above, do not work for everyone, so can only be considered as WorkArounds which may only work for a short period of time.

Am using direct Ethernet connection to an Airport Extreme base station. All devices other than my iMac work just fine on the same base station: I occasionally get total disconnect, and the Network Preferences say that my Ethernet cable is disconnected it is not. Rebooting fixes this problem, but nothing else seems to. Am pinging one of my websites as suggested above. Getting ping times of around 87ms. Running http: But when I access a web page with graphics that is not in my browser cache, ping times go as high as ms i.

Hello guys, The tip to run terminal to maintain data transfer was the right solution for me. Nonetheless I expect Apple to fix this properly. However, I am curious wether one of you can tell me: I have read a solution somewhere, forgot where but it solved my problem. Your Done! Works so far with me! The problem seemed to be fixed, but returned after a few hours of being in sleep mode.. Installed OSX Lion and now whenever my computer comes out of sleep I have to turn off my wifi under Network Preferences and then turn it back on to get it to connect to a network.

The issue started when I installed Lion. I have the same issue with Yosemite. I have to turn WiFi off and back on, takes a few seconds but an annoying issue. All this jumping through hoops when it is really a driver problem! Thank you Rys! Tried all the above suggestions, with little success. The connection problems were still there, albeit less frequent. However, switching to the Leopard driver really did the trick for me.

I waited a few days before mentioning it here, because I wanted to make certain that all is well now. And it is! Many thanks to Chris for his solution. Might just stay with Microsoft — at least their rubbish is a quarter the price. Lion has converted my Euro MacBook Pro into a useless piece of junk with dropping wifi, crashing applications and reduced battery life from 9 hours to 2.

I bought a MB air two weeks ago and I continuos to have problem with my wifi connection dorppinf all the time, every two or three minutes. My iphone and Ipad and other computers works perfect in same connection. Plese help wit this issue. My unusual situation is that I am staying at a motel and the network seems to be working for everyone else so I must assume its Lion. Usually once an hour or even sooner my connection would drop.

Restarting the computer sometimes brought it back but 5 minutes later would drop again. Either I must try restoring snow leopard or switching around some network settings. Any suggestions? Turn off computer hold down control option r and p then press power hold keys until u hear 2 startup sounds then everything will be fine. BTW, neither the 7. It actually seemed that 7. Come on Apple fix this issue once and for all! The 4. All problems go away when one reverts back to the 3. Thanks again go to rys! I have been dealing witha Senior Apple Care Technician who even fails to answre emails now.

Massimo Gullo. I love Apple products but am really disappointed by their current attitude towards customers paying good money. Frustrating thing is that opening terminal and pinging my router stops the issue. I told them that. Andy, they removed the link I posted with my post for some reason. It will provide instructions and the necessary files needed to revert back to 3.

Working great here! Andy, please note that your system has to be using the Atheros Wi-Fi driver for this to work. Typically the late iMacs utilize this driver. So check if your machine is using it first. Follow these steps: Can you tell me, I have done this on my normal non admin account — and verified using the admin password. Have executed it from Admin just in case.

I realised that I had not actually executed the script from the non admin account, just moved it into the Utility App. Andy, If your system is using this Atheros driver, then this is the fix. Yes, it should have been installed as an admin user. Under General of the info window you should see a version field and it should say 3. Processor 3. Card Type: Atheros Andy, then 3.

You can check it again by doing a get info on the file again, but this time it should say that the version is 3. Hey flashbak, thanks for the helpful tips. Do you know if this method works on a wide variety of Macs or only those intended to use that driver? Hi Matt, this info is specific to only those using the Atheros Wi-Fi driver. He details things nicely. I have opened that zip file, put it into utility run the script which ends something like have a nice day. Your early MacBook Pro with retina will work on wifi but after waking from sleep will not load web pages but wifi icon says it is still connected and you have to turn wifi off and back on for it to continue to work.

Get a different brand router and or modem. I have time Warner and had a arris wifi router modem combo and tried everything to fix this with to no avail. I have been dealing with this constant disconnect after sleep ever since my purchase of my first Mac Air 2 weeks ago. Many hours daily with AppleCare gave no relief. Finally Genius Bar gave me a brand new one! I was so excited and to my chagrin here we go again.

I followed the great directions of this fix to no avail!! I love my phone but I am beginning to hate my computer. Same problem experienced. Had to turn off the wifi and turn it back on. It usually take a minute to re-connect this way. Recently I tried something counterintuitive: The same for me, the only thing that worked for this annoying problem, thank you a lot for the help Passerby!

Thank you for posting this simple fix!! This has been driving me nuts. I wanted to say thank you for posting this. It would connect all by itself, then upon some update I performed everything changed. That was a hassle. I have on several occasions Googled for help with this, but never found this site, so thanks Dude!

So, can you please figure out how to make my wonderful laptop connect upon startup all by itself? Will you please let me know. I am 56 years old, and not very good at fixing this stuff on my own, but I can read so…. I have tried this on two machines that both suffer from this problem after having been migrated from previous MacBooks via Time Machine.

Getting real tired of this. I suppose I should actually clarify: The only thing that gets it to connect after that is turning off Wi-Fi, then turning it back on again. I still have to manually reconnect to my home network every time I wake from sleep. The solution? This worked!!!!!!!!!!!!!! Thanks so much!!!!!! This will save precious seconds for me!!! Initialization takes about 30s. So demanded wifi is not accessible immediatelly after wake-up. Thank you. This worked for me. Where does it come from and how do I get rid of it? I have had it for about months.

This is another weird WiFi-behaviour from Apple. God, when will they learn to create a proper wireless design??! Feeling frustrated. Solution seems to work for some people, not for others.
