Intel Mac :: OS X Lion 10.7.3 - WiFi Connection Drop During Surfing
May 6, 2012
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.

Why does my iMac continue to loose wifi connection? My PC setting right next to it does not have the problem. I'm trying to do the switch to iMac but having a tough time. My 1986 DOS PC with 20 Meg hard drive sure was simpler.

My one month old iMac does not maintain an interent connection for very long. Sometimes it stays connected for <maybe> an hour, but MORE often it drops either the wifi signal all together or just stops connecting to the internet... when it does seem to have a connection it is VERY slow. Â
My solution: turn off Wifi wait a few seconds and turn it back on... which is very annoying, but that fixes it. Â
I have the latest software across the board. I'm running wifi on Time machine. My signal is strong. I have a Powerbook and iPad that connects to it without issues (for a couple of years its been fine until this iMac problem).Â

I have owned my mac for some time now. I have an IMAC 24" and a macbook 13" black. Have owned the Imac for nearly 2 years and macbook for about a year. Absolutely love them and i made the switch from windows for various reasons.
After switching our ISP to "talk talk" (UK) I have noticed that when a windows machine boots up and the wireless is detected my internet connection either drops or cuts out all together. Sometimes having to reset the router. This doesn't always work though. This happens when either an acer laptop running XP Pro or Asus laptop running vista connects.
Im not sure if this is to do with the isp or weather its something in the mac that i could resolve.
I have tried contacting them but usually put through to a call center in India or talk to someone with a strong Indian decent accent. I personally find it hard understanding them so prefer not to call as i feel im being rude constantly asking them to repeat. Also tried signing up to the talk talk forum but it ask for my home number and also a number we was issued with when we bought the package, and i for the life of me cant find it!
Has anyone else had this problem were he internet connection drops? It's fine if i have macbook and imac running at the same time but when the windows joins connection drops or just fails. If anyone else has had this please post.

I was on my Mac and this happens somewhat often. I loose wifi connection and I have to go to the little wifi tab and select my network again. It doesn't ask for my password but it connects again. I am quite irritated with this, and it is embarrassing when my friends who have pcs come over "you have got a stupid Mac!" I love my Mac I don't want to ruin its great reputation.

I have a 2011 iMac 27 inch I purchased in around December. I have the most updated version of OS X Lion. My wifi connection to my router keeps dropping and losing connection. This does not happen to my other devices (MBP, iPhone, iPad). There was a fix for OSX Lion which worked for a bit but now it's happening again.

installing the 10.7.4 update on my 2011 iMac 27". The symption is that the iMac drop its Wifi connection after a period of time and when that happens the iMac cannot detect any wifi networks in my area (disabling & re-enabling Wifi on the iMac doesn't help). I have to resort to restarting the iMac to revive the wifi interface. Note that my other devices (including my iPhone and my MacBook Air)can connect to my Airport Extreme without any problems.

My imac constantly drops my wifi connection. Sometimes it'll last 5 minutes, other times less than a minute. And, yet other times, it'll go on for 30 minutes. I've tried deleting the network and the adding it again, reset router, changed channels on the router and countless other solutions with no success. Sometimes, it does not even find my wireless network! My ipad, my wife's macbook pro and my mac air all seem fine on the network and do not drop the signal. What is going on? Could it be my wireless card? Is there any easy way to check if I have a faulty wireless card?

Every 2-20 minutes, my iMac is dropping, then instantly resetting my wifi connection. The actual wifi drop lasts no longer than 5 seconds, and instantly reconnects itself with no input from me... the problem is it completely interrupts any downloading, streaming, gaming, or anything else I might be doing that requires a constant internet connection. It seems to drop off just long enough to stop the connection, then it resets all on it's own.
I'm currently using a mid-2011 27 inch iMac intel core i5 3.1 ghz processor w/ OS X Lion 10.7.3. I have a Linksys router and a GCI issued modem, unsure of the brand as there are minimal markings on it. The internet/tv service (run by GCI) is smooth throughout the rest of my home, and no other items we own connected to the net seem to have the same problem...
I have tried soft resets on both the modem and router. I have restarted my machine several times and re-added the network location and wifi connection to my computer. I have unplugged both modem and router to let those reset and have unplugged and reconnected my coax cable for several minutes as well. No time of day seems to work well, and it's becoming quite difficult to work and do other fun functions like stream television or game

Everytime I turn on the computer, there is no wifi connection. The symbol is still at the top of the screen, but is gray rather than black. I can click on it and it gives me the choice of my network or a neighbor's. All I have to do is click on mine and it connects.Â

For the last 2 weeks my wifi connection has been playing up. I use Wifi and my iMac connects directly to my router and it works slow if at all as some pages don't load. I can get by but its frustrating using it and this problem is specific to my iMac as every other device using Wifi works fine. These devices, that work fine, include mobile phones and a MacBook Pro.Â
I'm using Chrome and its the same with other browsers. I usually get a "resolving host' message in the taskbar when loading pages. Sometimes pages do not load at all or they are slow to load and at times some elements like images don't appear. My OS X is 10.9.4.Â

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?

I recently switched cable providers to Time Warner. They set up a Ubee cable modem and all devices (IPhone, IPad, AppleTV, etc) are all connecting to the wireless network except my IMac.  I tried renewing my DHCP lease, updating to OS X Maverick but every time I try and connect I get an error message that says "Connection Time Out".Â

Since installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

This weekend I upgraded my Macs to OSX Lion 10.7.3 and most everything is great. I spent some time trying to figure out why iCloud's Find My iPhone app will find my wife's MacBook Air and my iPhone 4 (iOS 5.1) but will not find my 2008 vintage MacBook Pro. I finally found one misconfigured AppleID and corrected that which then caused Find My Mac to report the MacBook Pro as "Offline" when it was clearly connected to the Internet (via Ethernet cable to my Time Capsule) and even logged in to iCloud itself. On a whim, I turned on WiFi and that did it. The MacBook Pro is now found and its location reported. I have not found any caveats about the Find My Mac requiring WiFi.

My airport keeps dropping and it is wasting so much of my time. I have tried all the methods suggested online and none of the worked. I want to go back to snow leopard but I don't have my disc. And can I have my money back from Lion? I really will not use that until it is fixed.

After switching to a new provider and getting a new dsl modem (a fritz!box fon 7390) I tried to setup my homenetwork again. Now the weird thing is: my Mac Mini running OSX Lion Server doesn't seem to be able to connect to the internet over its ethernet port, only when using a WiFi connection...When it's connected with ethernet it can reach the dsl modem without any problems, but it can't ping/telnet or anything else through, only over WiFi... As long as I use the mini servers WiFi connection everything works fine, but that doesn't make any sense to me.I've checked the servers setting and the Fritz!box settings and I can't seem to find anything obvious. Of course I could just go on and use the WiFi connection...
ps: all the other computers can connect fine using either wifi or regular lan connection... I even tried the exact same cable with another laptop just to make sure...

I am on a Mac Mini connected to the Net via a FON wireless router and Ethernet directly to my broadband modem. I have had problems with both the modem and an Airport Extreme, which eventually died, but I am back up again with the modem via the FON router.The odd thing is that I can't get Ethernet to work over a direct connection to the modem. Diagnostics tells me that the ISP and Internet fails. I can connect to the modem over Ethernet, however, change its settings etc. in my browser. There are solutions mentioned here involving changing the etc/authorization file, but wouldn't that also affect the WiFi if that was the problem?Â
In short, Ethernet connection to modem works. WiFi connection to FON router and then to the ISP and Internet works. But the Ethernet configuration does't go that last bit, it only works locally. Using that route, I can't connect to the outside world. I have restarted the modem, the computer etc., but that should not be the problem as both works over WiFi, using the same settings for the modem. How do I best troubleshoot this? I am getting an AirPort Express, perhaps it will work better with the modem that the computer itself, but I doubt it.

I've had the same internet connection for 5 years. Same wifi. Same password.Â
My previous mbp / os had no problems connecting and *staying* connected.Â
Now, with my 8-month-old MBP / OS10.8.5, I regularly get bounced off wifi and when I try to reconnect, I see my wifi in the networks list, but I get "a connection timeout occurred" fail.Â
Incidentally, my iPhones (4 and 5) over five years have *never* encountered this issue. They are on the exact same wifi / password / network as my MBP.

Since upgrading to Lion I've had the problem with wi fi losing connection and this seems to be common?The Apple support talked me through a change in system config. I'm no expert and not sure if I could repeat if needed.The support desk could not guarantee that this will permanently fix the problem though.
