OS X V10.7 Lion :: Mouse Often Loses Connection On IMac

Feb 18, 2012

I use my iMac for business. So even if the mouse loses connection once a day, that it 1 time too many. Some days it loses connection 2 to 3 times a day. When it does this, I go into system prefs/mouse and it says no mouse found. Sometimes it will find my mouse, then it after searching for a minute or 2, goes back to no mouse found and searching.

Sometimes it finds the mouse and sometimes it does not. Right now, I am using a hard wired mouse. Its been about 5 minutes and its still not finding my apple mouse. In fact, this all started after I replaced the original batteries. The mouse was working flawlessly up until that point. Its a brand new 27" IMac I got Christmas 2011, so its running Lion.

OS X V10.7 Lion :: 2Tb External Drive Loses Connection Whilst Using Time Machine

May 28, 2012

I have 2 x 2Tb external hard drives (Hitachi Touro Desk Pro), both of which have been formatted. I am using one of them for my entire iTunes Library, whilst the other one is being used as a Time Machine back-up for the first external plus the MacBook HD. 

All is fine with both drives until I go to use Time Machine. The external with the iTunes Library will just lose connection and I get an error message saying that "the disk has not been ejected properly and may result in damge...etc..." - just like the USB cable has been yanked out (which it hasn't). I then have to unplug it from the Mac and unplug it from the power supply, then re-conect it all for it to be able to mount again. 

Not sure why this is happening and am getting worried that this behaviour is going to damage the drive which has all my iTunes music, TV shows & movies on it, before I get a chance to back it up. 

Could this be an external drive issue, a cable issue or a Time Machine issue??

OS X :: Won't Work With Airport Connection / Loses Connection

Dec 8, 2009

Recently my MBP (mid-09) has had issues with airport as it continually loses connection and I have to turn it off and on again in order for it to work again sometimes within seconds of doing so. I would opt for a fresh install but my dvd drive seems to be scratching the dvds and it rendered my Windows XP DVD useless when I tried to install that. So it wouldnt be ideal unless there is a method of doing so without using the dvd drive.

MacBook Pro :: Loses Wireless Connection When Asleep

Apr 15, 2012

My 2011 Macbook pro i7 has a chronic problem: as soon as it goes to sleep, the wireless connection is lost, and has to be manually coerced back to the computer by turning the wireless off, waiting several seconds, turning it back on again, and waiting for it to find the router again. It finds the router in a few more seconds, then everything is OK until it goes to sleep again.  

A real pain in the butt, and shouldn't be a problem on a supposedly high end computer.

OS X Mavericks :: 10.9.3 / MacBook Air Loses Connection To Internet But Not LAN

Aug 22, 2014

I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here [URL] ...., which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem). 

I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection.  

My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes: 

1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets

2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).

3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.

4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets. 

The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.

MacBook Pro :: Loses Internet Connection Upon Waking

Jun 24, 2014

Just got a new MacBook Pro a few months ago. Migrated everything successfully from my old MBPro. Now, however, when I wake my computer each morning, it can't connect to the internet. It shows that my wifi is connected, but when I try to get mail or use Safari/Firefox/Chrome, it just spins until it tells me I have no internet connection. I then have to restart the computer and it works fine after that. 

The fact that it works fine after restarting tells me it's something other than my wifi or my cable modem. 

I'm running 10.9.3. Using 'Automatic' location.

MacBook Pro :: Wireless Loses Connection Every 10 Mintues / Sort This?

Nov 16, 2010

Everything was ok until last night when I noticed this. I'm sure I didn't change anything manually in the network settings, but now I can't keep a connection for more than 10 mins. To get it back again I have to shut the airport connection (checking the diagnostics, I get a red light on the ISP circle,yellow on Internet and server) and that lasts me another 10 mins

so far I've tried sending pings, deleting this network entry and adding it back,changing the router position, but no luck. I'm able to check the router settings (tp link), but not sure what I should be looking for

the laptop works fine at my sister's place. It's just this network at home I'm having troubles with. the same thing happened all of a sudden with my imac,so I left the Ethernet cable connected to that, as it's right next to the router and it works fine.

Intel Mac :: Loses Wireless Connection After Wake Up From Sleep Mode

Feb 23, 2012

My iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network.It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

It keeps on losing connection, like during the times I have to lift it up and then put it down, or when I stretched my arms a bit, covering not much distance with it away from the laptop. The battery, as I type this, is at 91%. I'm still using it, but a little this or that, or like when I bump my knee into the table, it goes off. This is the version I currently have:

IMac :: Wireless M Mouse & Keyboard Lose Connection Effecting New 09 Model

Mar 21, 2009

I just purchased a new iMac 24" 2009 Model. I also got a Wireless Mighty Mouse & Wireless keyboard. I have owned the system for 6 days and each day the Mighty Mouse and keyboard will lose connection and require me to hold the power button down on the imac to restart the system. I called apple and was told to do a "Option Command R P" Reset. This did not fix the problem... I then called them again and was told to format the system.. This did not fix the problem.. I replaced the batteries, turned bluetooth off on any near by devices changed my 802.11 freq to a different channel. It seems from information collected from other forums that this is effecting mainly the new alum 2009 imac...I am starting to think this is now hardware. Also something I noticed.. Brand new FRESH Energizer Ultimate Batteries $25. I put them into the mighty mouse. 1 day later iStat reports the mouse is at 73%!! thats a big drop in 1 day

Mac Mini :: Mac Mini - Computer That Loses Airport Connection?

Aug 21, 2009

I have the current generation $599 Mac Mini, with Nvidia graphics (just to clarify the model).

My wireless network is setup from an Airport Express.

My iMac, Powerbook, iPhones, Apple TV, Wii, etc. can all stay connected without problem.

However, my Mac Mini loses the connection constantly. It shows full signal, but then it drops out 100 percent for a few minutes, nonstop all day. It makes it completely useless effectively.

What kind of settings and things could I try to change?

Or, is this likely a hardware issue?

IMac :: How To Fix Hinge Loses On 2010 I7?

Aug 11, 2010

I searched the forums but can't seem to find a definitive answer in regards to having a loose hinge on the i7.

I picked mine up yesterday and it seems a little too lose for my liking. It stays in place when it is not touched, but if you push with one finger on the bottom it will switch quite easily.

Is this how they make the hinges now or is mine too loose and should be exhanged? I don't seem to have any problems with dead pixels/yellow screen/noise and would hate to exchange it.

IMac :: Computer Crashes And Loses Hard Drive When Goes Into Sleep Mode?

Dec 21, 2009

I just had the original 300 GB hard drive fail in my aluminum 24" inch iMac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.

So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates. I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.

So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great.

So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.

However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.

I think maybe there's an issue powering the drive back on? Anyone have any ideas?

And my follow up posting later that day:

Quote:

So I ran some tests just to see if was an overheat issue, hard drive malfunction, or sleep issue. I decided to start encoding a video, pulled up Word, Power Point, Excel, started downloading all 6000 mail messages off my server (I never delete my e-mail :-/), also started installing iLife 09, and pulled up a bunch of webpages in Firefox with multiple tabs.

However, I shut off all sleep mode options on the hard drive. I let it run for an hour and came back. Everything is fine, hard drive isn't locked up and smcfancontrol shows the hard drive running pretty hot (115 degrees) but not so hot I'm worried. So it's definitely something to do the hard drives going into sleep mode and not powering back on. It's also weird that I have to leave the computer completely unplugged for 10-15 minutes before the drive is recognized again.

So turning off sleep seems to be my work-around, however, this shouldn't be a long term solution. I'm worried that there is a bigger issue with the iMac, but I'm not sure what would cause this. I've been a PC guy for years, this was my first Mac, and honestly I don't know enough about the inner workings to narrow this down. I would assume this would have to do with the motherboard in some way? But I'm not sure how you would even test it.
