OS X V10.7 Lion :: 21.5 (2.7 I5) 8GB 10.7.3 Keeps Dropping Its Internet Connection?

Feb 14, 2012

I have an iMac 2.7 i5, 8GB, OS X Lion 10.7.3.  I purchased this iMac just about 3 weeks ago and from the beginning experienced regular dropping of the internet connection. I have cleared all other networks that appeared in the Preferred Network window other than my own. I have also unchecked the "Remember what other networks this computer has joined" box just in case I needed to. No luck. I am using an ATT 2Wire wireless router that's just over a year old but I haven't experienced the connection drop problem with an older Macbook (about 4 years old) that I also own.

OS X V10.7 Lion :: Keeps Dropping Ethernet Internet Connection?

Mar 5, 2012

I know this has been a wifi issue for many, but this is occurring with ethernet as well on our iMac 2.93. Only began with Lion update. All other 5 Macs (Snow Lep/Lep/Tiger) and several PC's on network have no problem. Have set iMac's internet connections to static/manual ip. Worked for a few days, then back to dropping. This is obviously an OS issue.

Intel Mac :: Internet Connection Keeps Dropping Out

Jul 6, 2012

I have an iMac (without an Airport Base). It is connected to a Sky router through an Ethernet cable but still with wireless capabilities. The internet connection keeps dropping out at regular intervals throughout the day to the point that my partner may just throw it out the window! The router lights still show it is connected as does the wifi signal at the top of the screen. Our iPhones still work even when the Mac drops off.

OS X :: Internet Connection Keeps Dropping Connection?

Aug 12, 2009

I know there are a lot of similar threads all around different forums, but nothing really helped and I was hoping some of you smart ladies/guys can help solve this issue once and for all.

Here's the deal:

My main desktop computer (Compaq windows XP computer) is set-up upstairs where the cable router and linksys wireless router are placed (which is right next to the desktop on the desk). My Macbook (running Tiger and is 3 years old) and iMac (running Leopard and is not even 1 year old yet) are set-up downstairs in my new office. This room is in the basement, however the room is almost directly above the main office where the wired desktop computer resides.

Prior to setting up my office downstairs, my sister lived with my family in the basement and had her windows Vista laptop set-up without any internet connection issues. Her internet never dropped on her laptop, and neither did the connection on her wireless all-in-one printer/scanner/copier. Cell phone reception/internet connection in the basement is also great.

When I set up my iMac and Macbook however a few weeks ago, the internet keeps dropping connection! I do not understand this when my sister had no problems at all with her laptop getting internet connection, when she was living with us. The internet connection will stay good for either 10-30 minutes and then drop, or it could be good for up to an hour and then drop.

Intel Mac :: Dropping Internet Connection Via Airport

Mar 19, 2012

Since last week my iMac (Early 2009, OS 10.7.3) has been dropping its connection to the Internet. I'm using a router connected to an Airport Extreme and connect to it via WiFi. I tried connecting via Ethernet cable from modem to iMac but it would drop the connection entirely, which is why I had been connecting via WiFi. I have no problem with my other devices (iPad, iPhone and MacBook, this one with 10.7.2 installed), they connect immediately to the Internet and all, even the iMac, are able to connect to each other. 

I already tried restaring the Airport Extreme, zapped the PRAM, reset the SMC, repaired permissions, disconnected the router and Airport from the power source and it still won't connect. Last time this happened, my iMac went to sleep and dropped the Internet connection after waking. I put it back to sleep and woke it using the power button as someone had suggested in another post, that helped and the connection was reestablished. This morning the iMac it was working fine, did not go to sleep at any time and suddenly dropped the connection, which I haven't been able to restore since.

MacBook :: Internet Connection Dropping Every So Often (15 Minutes)

Jun 28, 2014

I'm having a problem maintaining my internet connection. Every so often (~15mins) my computer loses its connection without warning. I have an old MacBook running OS X 10.6.8. 

The problem started yesterday when I lost connection. Going into network diagnostics everything was green as far as ISP - Internet and Server were the only ones failing. Restarting the router/laptop did nothing, and no-one else using the router had any connection problems. Eventually, the problem was "solved" by renewing the DHCP Lease, except that now the connection drops. It can be restored by going through the Diagnostics and is usually fixed when I reselect my network, whereupon it works fine for a while before being lost, which I usually discover when trying to load a page. 

I have tried restarting the router and laptop, I have tried renewing the DHCP Lease again. Once again I'm the only one on the router experiencing connection issues.

Hardware :: Internet Connection Keeps Dropping - Using Airport Extreme?

Mar 16, 2009

I have just recently started having this problem. It seems when the computer sits idle, the connection drops. I don't see my network in the dropdown menu. I open airport utility, and the extreme base station does not show up. I find I have to unplug it, or do an actual reset on it to get it to show up.

I try resetting the cable modem as well, but I have never had issue with the internet connection itself here before. I try restarting the computer. When it does come back online/show up in AIrport Utility, it seems kind of random because it will take a few attempts at all 3 methods mentioned before it just suddenly appears in Airport Utility. So I really have no idea what is helping. The process is a pain in the butt though.

I have searched around, but I can't find many current articles on the problem.

The only other info I can offer is that I never had any problems until I installed the last Airport Utility update. I am running 10.5.6. The problem doesn't seem to happen while I am working, and online frequently.

I don't even know where to start trouble shooting.

Hardware :: Airport Extreme Dropping Internet Connection?

Nov 1, 2009

I have a 3 month old Airport Extreme Base Station(dual band) running a secured 2.4 and 5GHz network.

It is dropping it's wireless internet(not signal, just internet) on my 13" Unibody MBP at least 2 or 3 times per day. Not at a certain time, or under certain circumstances, and I can't replicate it. My computer will continue to see the networks(named airFORBUSH and airFORBUSH(5GHz)), but there will be no internet, and it won't stay connected to them. If I connect to the network named "FORBUSH", which is our Linksys network, it connects and is up and running again, so I know it's not our ISP.

Here's my setup in my house(I'm the only one having this issue, since I'm the only one running wireless on the AEBS

Hardware :: Xbox360 Keeps Dropping Internet Connection To Time Capsule?

Jan 24, 2010

I seriously need your help with an ongoing issue that's been affecting my time capsule for a few weeks now. First of all, my Xbox360 is connected with a wire to my time capsule and now, it's pretty much impossible to play any games online. In Modern Warfare 2, I get horrible lag and after a game or two, the disconnected from xbox live appears and the only way for me to get back the connection is by unpluging the Time Capsule and restarting the Xbox. This gets me a good connection for 30-45 min and after that, same problem. I don't really know what could be causing this since I also lose connection while playing a single player game that doesn't require any incoming data. Sometimes, I just turn on the console, I see the xbox icon searching for an internet connection and then nothing.

I really need your input on this because everything else connected to my Time Capsule works perfectly (PS3 and Wii wireless and a Powerbook wired). The Powerbook never loses the connection.

May 24, 2012

Equipment: iMac 21.5" 2.5GHz Quad Core i5  

Internet Set-up: Cable modem to iMac Ethernet 

Problem: After recent update to Lion 10.7.4, my Wi-Fi signal via Internet Sharing keeps dropping. Have multiple iDevices failing that were working perfectly with 10.7.3 (Nook and iPhone 4). iPhone shows full Wi-Fi signal strength and works for a short time after reset (via Wi-Fi off/on, Internet Sharing off/on). Continues to show full Wi-Fi signal strength but loses connection after 1-2 minutes. And not just internet connection; I can't transfer pics/vids from iPhone to iMac either. Have switched to a channel no one nearby is using (channel 9) to no avail.

OS X V10.7 Lion :: Force System To Use Second Connection Of Network Connection List For Internet Access?

Jul 5, 2012

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?

OS X :: Airport Connection Keeps Dropping Connection To Computer

Jul 29, 2010

Two computers in the house MacBook and iMac, running on an Airport Extreme network, which includes an Airport Express plugged into the stereo.

A brief power outage the other night (perhaps unrelated), and in the morning, the network was wonky: the iMac was only getting two or three bars, streaming radio to the Express kept flickering on and off. When that happens, rebooting the Airport base station, the router, and the Express usually takes care of it.

Since the reboot, the iMac hasn't been able to keep a connection to the network, and often can't find it. It may start off, but then loses the connection and then times out trying to reconnect. Or the network doesn't even appear in the list. Read that launching Network and running Diagnostic will fix problems and it sometimes does, but never for long.

All this time except for one brief bit where it suffered the same problem the MacBook has had no problem connecting to the network and the Internet.

Have rebooted everything multiple times in various orders, run Disk Utility, and even gone ahead and upgraded the iMac to Snow Leopard (laptop was recently upgraded).

OS X :: Wireless Connection Keeps Dropping

Nov 27, 2009

I just bought a MBP 13 inch in August '09 and Ive been experiencing consistent dropped internet connections wherever I go. I'm in college right now, and I have wireless internet at my dorm and my connection keeps dropping randomly and the only way I can reconnect is by turning on and off Airport. I just went home today and Im experiencing the same scenario with my Home Wireless Network connection. Anyone know whats going on or how I can fix this?

OS X :: Wireless Connection Keeps Dropping On IMac C2D?

Jan 24, 2007

My iMac has been connected wirelessly to my D-Link DI-604 802.11g router for near 4 months now.

About 3 days ago, the iMac started to exhibit strange problems.

Every 3-4 minutes, the connection drops.

The airport icon at the top shows full bars (and the router is about 2 feet from the iMac) but the internet does not work anymore.

Also, if I deconnect and try to reconnect, at first it gives me an error ("there was an error connecting to network XXX"), then my network disappears from the list for 1-2minutes and then I can connect.

I think it has to do with an authentication problem but the password is correct etc.

I don't know what may cause this.

My PC with a wireless card is unaffected.

It seems to be a software problem with my iMac.

OS X :: MacBook Airport Keeps Dropping Connection?

Feb 20, 2008

I have had my MacBook sense Oct. 2006 and not until recently had any problems with the airport. Currently it will connect to any network as per usual and then with out notice just cut out for a few seconds and then come back on.

This isn't a huge pain if Im just browsing the net but if I am trying to hold a conversation using skype, IM, or downloading things it can get very very annoying. It cuts out about every 2 mins. It is not a problem with weak signal because when it is on it is showing full bars.

I have tried it under both my home network and my university network both resulting in the same thing. Is this a hardware issue (crossing fingers it isn't!)? Anybody having similar problems?

Hardware :: Dropping Wifi Connection - App?

Apr 11, 2009

I work for a business that sells a lot of computers, Macs specifically. We've got a wi-fi network in our building; however, the network constantly drops out. Despite our pleas to IT, they will not fix the issue. Our demo computers that customers can play with and consider purchasing often lose Internet access because of this. Whenever this happens, I have to manually turn the Airport off and then back on again, which will get it to reconnect. Does anybody know of a way to have the computer automatically do this every so often?

OS X :: Macbook Pro Keeps Dropping Wireless Connection???

Aug 27, 2009

Is there something wrong with my computer?? Some special update that I don't know about?? this is so annoying!! I'm running Leopard 10.5.8 but this happened also on 10.5.7 and I am using an early macbook pro model - about 3 years old. I will be connected to the wireless fine all day then like right now it drops the signal and i have to hook my computer up to an ethernet cable. I can restart modem, router, and computer but I haven't found a solution except to try again in a couple of hours and it will work fine. I know it's a problem with the computer itself and my apple care just expired so i hope it's not a hardware issue. Anyone know anything? I've tried changing the password protection on the router but still same result. Just pissed off that my $3000 computer can't hold a wireless signal.

I recently upgraded to Lion OS X v 10.7.3, and i like iMail 5.2 when I work from my office or home.BUT, when I am working in the field I often have access to only glacially slow internet via an internet modem, and iMail takes FOREVER to download my messages. Way longer than my pre Lion version of iMail.Is there a way to optimize iMail 5.2 in order to optimize for slow internet connections? For instance, to partially retrieve large messages? Or to somehow deactivate all the synchronizing and other Activity that goes on in the background?

OS X :: Wireless Connection Dropping At Random Times?

Dec 2, 2008

I'm using a Macbook 13" and am running 10.4.11.

So the problem that I'm having is that at random times I lose connection. At the same time the PC-s that are connected to the same network have connection, plus the ISP said that everything seems to be fine on their side. So there seems to be an issue with the WiFi on the MB. It just loses the connection and can't find it for about a minute and some times it takes about 5 minutes for it to reconnect to the network. And the problem isn't limited to only one network, but actually happens in different networks. It started as a minor inconvenience, but now it's starting to really bug me. And it seems that I'm not even making it up: [URL]
