OS X V10.7 Lion :: IMac Randomly Disconnects From Internet (WiFi Via BT Hub)

May 26, 2012

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

IMac :: External USB Drive Disconnects Randomly

Jun 12, 2010

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.

I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?

OS X V10.7 Lion :: Bluetooth Audio Disconnects WiFi On 10.7.3?

Feb 22, 2012

I've had problems related to both WiFi and Bluetooth ever since going Lion. However, after updating to 10.7.3 (the large update) from 10.7.2 the WiFi always drops whenever I switch my Bluetooth audio on. It resumes  after disabling the bluetooth audio. Please note that Bluetooth is always on in both cases, I just switch the audio output. Tried resetting SMC and PRAM - didn't work

OS X :: External Hdd Randomly Disconnects?

May 18, 2009

I own a few external harddrives, however one in particular (western digital 2tb) will randomly disconnect and a window will show about "device removal with the red little stop sign shape" then it will randomly connect again (and sometimes i have to physically unplug it and plug it back in), does anyone know what is going on here? None of the cables are being touched, it's really strange, the only thing i can think of, is maybe i have a loose usb cable and need to replace it? or maybe a faulty usb port?

PowerPC :: Airport Disconnects Randomly - Reconnect Attempts Time Out

Aug 27, 2010

So, after getting it hooked up and connected to my router, which is set to only allow only 4 devices to have access to it (my comp, iphone, wii, and gf's laptop), i find that my gf's laptop (which is the only device using a corded connection) is the only machine able to get online without problems now.

I can pick up my WiFi network occasionally after a restart, but then it usually goes out after a random amount of time... anywhere between 10 minutes to an hour or 2.

PowerPC :: Ethernet Not Working Properly - Randomly Connects / Disconnects

Oct 11, 2006

I've been having problems staying connected on my Powerbook G4. The wireless works perfectly but the ethernet does not. I've been using the dorm ethernet jack to connect. The problem is that my computer can't maintain a consistent connection through ethernet so it randomly connects and disconnects. I called my campus' IT department and they told me that it must be my computer because they're system said that it didn't detect my computers IP address. I called Applecare and the person told me that it must be something wrong with either the network card or the ethernet port. Anyway, he gives me a case number so I can go get a repair. Unfortunately an Apple Store is far away from where my school is so I went to my school's bookstore instead.

The bookstore is an authorized service place. I drop the computer off to them and they sent it to Apple. I got a call today from the bookstore guy saying that the Apple technicians discovered that "liquid" had gotten into the motherboard and refused to service my computer. I was really angry when I heard this because I keep absolute care of my laptop. I know for a fact that no water has ever been around my laptop. I'm guessing it must have been negligence on the bookstore's part. I declined the $1300+ repair estimate so now its on its way back to me. I have a brother that works at the Apple Store and he just suggested going directly to an Apple Store this time. Will they just refuse warranty repair again?

MacBook Pro :: System Randomly Disconnects Usb Device / Port Fails To Recognize IPhone

Dec 15, 2010

I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?

Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.

Intel Mac :: Constantly Losing WiFi Randomly While Working

Apr 19, 2012

I am running an imac 24-inch Mid 2007 on 10.7.3. Always do the updates and everything seems ok. I have been having problems with connecting, reconnecting after sleep and just losing my connection in the middle of being on wifi. I have replaced my wireless router, I have deleted all previous wifi networks. I have also renewed my dhcp license. Nothing works. To reconnect, I have to continuously go to network preferences, assist me, diagnostics, then continue with the assist me and choose my network and it then reconnects. This is not just waking from sleep. Sometimes just randomly while working on the computer. I have†read some things about equipment plugged in and I have an ATT micro cell plugged into 1 ethernet jack in my wireless router/modem, I also have a bluetooth mouse, a printer plugged in USB and a Lacie HD using Time machine.
