Intel Mac :: WiFi Disconnection With Lion?
Feb 18, 2012
The Wi-Fi keeps disconnecting (all networks), although they continue to be available on my iPhone, Mac Book Air (OS X Lion 10.7.3) and another PC. I have to reselect the network manually in the shortcut (top right of the screen), a few seconds later I am connected again. The problems seems to be related to inactivety on the iMac. For example if you are reading some pages, without any key strokes or mouse activity, but there does not seem to be any specific time for repeatability of the problem. It is just anoying. Tony Processor 2,8 GHz Intel Core i7 Software Mac OS X Lion 10.7.3 (11D50b)

Every 5 to 10 minutes, my MBA "seems" to disconnect from the internet, although according to my Mac, it's still connected and shows my current IP address. I know it's not my router (Dlink DIR-624) because everything else stays connected. I don't have a problem with my Dell laptop, AirPort Express (used only to stream iTunes to my home theater), iPod Touch or either of my iPhones. The problem only occurs with the MBA.
Renewing my DHCP Lease fixes the problem for a couple minutes, but then I lose connection again.

Putting her MacBook Pro/Maverick to sleep works fine, but when she raises the lid the Wifi connection is broken, and cannot be acquired unless she reboots. Does a switch exist for this anywhere?

My Lion OS 10.7.3 iMac just does not seem to be able to hold a stable connection with my home wifi network. After around ten minutes, sometimes more, sometimes less, usually when I've gotten up to do something else, the wifi is lost. It stays "connected" to the network (ie the wifi bars are black) but no internet comes through. Every time this happens, I turn WiFi off and reconnect and it fixes it every time, but it is still extremely inconvenient and troublesome to have to redo this constantly.

I just got Lion and a new iMac. It disconnects the wi-fi everytime it goes to sleep. This messes up my vidoe uploads that take more than a few minutes.

I've iMac OS X Lion 10.7.3 latest version desktop. For couple of months, I'm dealing with dropping wifi connection during working. Every a few minutes, even during surfing though internet pages, wifi connection drops. When you look at the signal level etc.. everything is seems to be fine, but it is not possible to connect internet after close-open wifi. For a while, connection drop happens again.

I upgraded to Lion after its release and ever since then my wifi has been driving me crazy. The wifi disconnects, and when I click on my network I get the error that the connection timed out. I'm always forced to turn the wifi off and then back on. It happened a ton, and consistently. It's extremely frustrating especially when I'm in the middle of a movie on my Apple TV and my iMac loses its internet and interrupts the show. Sometimes it happens three or more times during one show. So I decided to do a clean install of Lion. I made sure all my important documents were on my Hard Drive and even wrote a list out of every application that I use regularly. Then I completely reformatted my hard drive and did a clean install of Lion.

When using PC, WINDOWS warned about not to disconnect USB/FW connected hardware until you ask the system to do so and the system confirmed it was safe to do so. However, I've been told that with Mac you can directly connect/disconnect the cables without any previous confirmation from the system. I'm confused, since I can not find how to get confirmation form the MAc that it is safe to disconnect the USB/FW.

I've got a strange problem with one of two internal HDD on my PowerMac G5. All of a sudden, it disappears from the desktop with an error message about improper devise removal. I've checked the cables: everything is like it should be. After restart all drives are back at the desktop. But it keeps happening fsck didn't help. I'm running DiskWarrior right now. What could it be? Both drives are quite new Seagate 7200.10, I think... Not older than 1 year.

I accidentally unplugged the surge protector 2 days ago. When I replugged it in, the computer was not turning on. The green light on the tower was on, but with absolutely no signs of life.

I recently bought a late 08 aluminum macbook and have been quite happy with it but from quite some time I've noticed that while I'm on internet and on adium (where I noticed the most) the signal goes off for a couple of seconds and then it comes back. First i thought it was ok but it's been happening really often and is quite annoying since it happens several times a day and only happens to me and not anyone on my network (everyone else has pc`s and are also on wifi). So I wanted to ask.. is it possible my Airport card is failing? or is my router the one failing.

I have four external drives connected to my MBP: One USB 2.0 drive, and three that are connected via FireWire 800 (they are connected "in line", i.e. one is connected to the MBP, the second one is connected to the first one, and the third one is connected to the second one).For several months already, I experience the following anomaly:When an external drive hasn't been used for a while it normally goes into sleep mode and the otherwise turning disks come to a standstill. The problem, however, starts when I want to use the data of one of the "sleeping" drives (e.g. by opening the Finder): Then one or more other drives, that are also in sleep mode, but used to come back into "active" mode in the past, are suddenly disconnected. MAC OS X then displays the message that a disk has been disconnected without being formally ejected (via the dustbin). This is not normal, of course, and I am afraid that this behaviour could harm the disks health and live time.I have tried the Disk Utility Tool of OS X for all the drives mentioned, but they seem to be ok.

I've been having this problem for awhile- maybe some of your intelligent people can help me.
I have an airport extreme and two 1TB hard drives connect to it through a USB hub.
Every night, I have a program that copies one of the hard drives on to the other. This has worked for the first year that I had the setup.
Recently, when copying, the mounted hard drives will disconnect and I will loose my internet connection. When this happens, the green light on my airport extreme turns to yellow and starts flashing- is it is restarting.
This also occurs if I manually try to copy a large batch of files.
I'm usually decent at debugging computer issues, but this one has me stumped.

I've had an WD My book 500 GB external for about as long as I've had my macbook about 1 1/2 years. No trouble with it at all, until yesterday. At some point either the power got cut or the cable was pulled out incorrectly it got disconnected from the mac. Thus resulting in it not mounting now. I've tried disk repair and shutting down the macbook and restarting...plugging in after everything is started. but to no avail. I am a photographer and about 25% of my photographs I don't have backed up anywhere else. So if I can't get it to work. I need some way to get the information off and reformat. or get it working correctly.

Wi-Fi connection often stops after lion has been asleep. Other devices have no such problem. All was fine until this week. Lion is barely 3 months old. It's not a drag to reconnect, but should I have to?

So I've got an odd problem, here's the scenario: 27" iMac 2.8GHz Quad Core running OS X 10.7.1, and a netgear router (connected to a Comcast modem).It sees the network, connects then drops the network. However, a MacBook Air running 10.6.8, an iPad, and a Sony Viao running Windows 7 can connect and stay connected to the network fine.This made me think that something with the iMac's WiFi card is broken so we brought it to work and connected it to our network (802.11x, WPA2 Enterprise, Cisco routers) and it worked perfectly. He brought it back home, still couldn't connect to his network.We brought it to the campus Apple store and they replaced the airport card and it seemed to resolve the problem for a bit, but now the issue has come back.Yesterday we did a full time machine back up, wiped the hard drive and did a full OS X Lion re-install and restored from the Time Machine back up, ran all of the Apple software updates and it connected to the WiFi here at work fine.Brought it home, still won't connect to his network. This would make me think that it's an issue with his home network but all the other devices are working fine.We had a Comcast technician look at the network and they found nothing wrong.

This only started after I upgraded to Lion. I would swear I saw it in an update from Apple after that, too, but the iMac doesn't find any updates and is still doing it. When I wake the iMac, it doesn't go look for wifi. I have to click on the symbol and choose the network. Since I'm used to just clicking Safari.

I have an older (white) iMac that connects wirelessly to my Linksys router. I bought a new iMac and I am unable to connect both iMacs wirelessly at the same time. I was wondering if the issue had to do with using the same Apple ID's, but I don't think that is the case. It seems like the old iMac is connected to the router, the new one wont connect and vise versa.

i have a 2010 imac and it is very slow on wifi,i have done a side by side test with my macbook pro in the same room,the mbp gives me 45mb download speed while the imac gives 16mb . the only way i can get it faster is to unplug it from the mains,it will then be similar to the mbp,but will slowly get worse again over a few hours. i have tried all the solutions on the forums,the os is up to date.

I've seen this question asked before, but it was all related to people who are running lion. I have 10.5.8, which I believe is leopard. Whenever I try to connect to airport, I get my network from the list, enter the password then I get a connection timeout after about 15 seconds. We have had this problem for a while now. We just got a new router this week and I'm still have this problem.
