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.

Randomly, my computer seems to be disconnected from my wi-fi network. It is not a routeur problem since every other devices still work when the computer doesn't.

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?
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.
Info:iMac (27-inch Mid 2011), Mac OS X (10.7.2), Lion disconnecting from wi-fi
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 Â

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?
View 4 Replies View RelatedFor several weeks I've lost internet connection on my iMac every day or so; the wifi icon changes to show a ! and is otherwise greyed out. My internet connection is via a relatively new Time Capsule (2011) which has an ethernet cable connecting it to my Sky broadband router. I moved to this new Sky broadband router in early Jan 2012 (changing to Sky as a Broadband provider) and it works nicely as a router. My iPhone, iPad, AppleTV and a range of other devices (including an Apple Airport Express connected to a Sky TV HD box to enable it to download movies) have continued to work on the internet without problems.
The IP address of the iMac (27 inch quad core i7, 8 GB RAM, fully up to date on Lion) disappears from the Network settings when the problem arises but the connection of the iMac to the wifi (and backing up to the Time Capsule) still works. I can even use a VNC app on the iPad to connect to the iMac on the same wifi LAN when the IP address has gone and the ! is showing in the wifi icon on the menu bar. To get reconnected to the internet, I just restarted the iMac and it was then back accessing the web nicely. Eventually the iMac would not connect to the internet at all. It would momentarily get an IP address from the router and then lose it again. I then tried taking the iMac to the Apple Store.
Various diagnostics run in store at Genius Bar and during the week and the problem (using the same account) was not replicated. On its return home, it was still not working on the internet. I then tried booting into 'safe mode'. This enabled a stable and reliable connection to the internet! After several days in this mode, I re-installed Lion and booted into normal mode again. The problem returned and has been with the iMac since. However, at least a restart of the iMac gets it straight back on to the internet again. I suspect some sort of corrupted network preference file or the like. But where? The disconnection from the internet can happen any time of day; for example it happened while typing this message but more often than not it happens when the computer is unattended.

I recently purchased the $1699 Macbook Pro a couple of weeks back and now it seems that my airport randomly turns off. I can't even get it to turn back on; I have to restart my macbook to get it working again.

Also the drive has been reformatted to a Mac format, but it still continues to do this.

I just bought a $107 (au) wireless keyboard for my 24 inch 3.06 GHZ last gen iMac and upon installing it the Wi-Fi has been dropping out randomly. I checked bluetooth update and software update and it is all up to date. What do i do?
View 7 Replies View RelatedI have full Wifi signal and I'm using multiple device on my Wifi which are all stable except the iMAC. We had a power failure a couple of weeks ago and since then the iMac just won't stay on the network. I have to turn wifi of and then back on to get it to join and that mitt lat 10 minutes.
View 4 Replies View RelatedSo, 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.
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?
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.
Recently my macbook (running snow leopard) has started disconnecting from wifi after about half an hour, this is getting really frustrating, how can i stop it?

My internet provider says it has a good signal. whether i use wifi or connected straight to the modem its the same, some pages load some dont, always different on what loads and doesnt.  If i connect to a neighbour who has the exact same internet speed and provider it works perfectly fine. Ever since i did a software update 3 or 4 days ago it has been happening.

I've got a MacBook 3,1 (White, late 08 model) which is happily connecting to the wireless network but refusing to use the internet. Other computers on the network use it fine.
What's more, when I restart to my bootcamp partition, the internet works fine. It's only in Mac OS that I have a problem.
I just bought a MacBook. So far I am loving it. Unfortunately a very strange thing happens. Whenever I download something with the Macbook every other device at my house becomes unable to connect to the internet until the download is finished. It doesn't matter if it is a WiFi device or not. The connected devices are: a WinXP Netbook, an ubuntu9.10 desktop PC (please notice this is connected with an Ethernet cable, it's not wifi), a WiFi and a Samsung Bluray reader. To complicate things even further, I noticed that even the MacBook itself cannot do anything else (such as browsing the web w/ Safari and/or Firefox). I tried to download large files such as a movie from iTunes store and the iPhone SDK. The download rate is about 600Kb/sec.

My laptop drops the wi-fi connection every time the cover closes for sleep mode. It just started doing that recently. What settings should I do to make it stay connected? My other Apple devices continue to work normally.

I've recently moved into student accommodation, which only has wired internet access in the rooms. This is fine for my MacBook, but causes problems for the iPad! So I've been attempting to share the MacBook's internet connection through AirPort using the "Internet Sharing" option in System Prefs->Sharing. This works great, but after a while it disconnects for no apparent reason.
View 1 Replies View RelatedEvery time my macbook is in sleep mode the internet disconnects (msn messenger shuts down, download stops etc.). I am not talking about closing the lid sleep mode because I am in desktop mode with an external display. Once I woke up my macbook it reconnects. Does anyone know how to stop this because I think it happened after 10.5.6.

I cannot be 100% sure but it seems like my problem started when I installed Apple TV and started home sharing. When my Mac goes to sleep and I start it up the internet is disconnected. I check in the settings and the network shows a signal and connected. I do not get emails and I cannot connect to the internet though. I have to restart my computer then everything is back on. I cannot stand quitting all my work to restart my computer so many times a day.

Recently got the new Mac pro and the internet connects briefly via (wire less) and then disconnects after 30 secs. I notice the DNS server switches numbers. After this happens I no longer have internet connection.
Connecting via ethernet is no good either. It doesn't connect at all. I did do a migration from another system. I am wondering whether the setting were saved from my previous system and are getting corrupted with the new system.Â

In the studio mixing, trying to connect my iMac (10.5.8) to their Netgear Wireless. Airport sees it fine. But no Internet. My 3GS has Internet thru it just fine.
I had this problem once before with an older iMac, and seem to remember deleting certificates, then renewing DHCP lease. Tried doing the same thing again (just deleted all certificates under Keychain), but still no Internet.
it is possible to generate a good wifi signal with my new imac which will allow mw to connect to the net with my wifi ipad2?
