Bluetooth - lost connection (again)

There have been many posts on this and I have even offered advice on it before, but I still occasionally lose my Bluetooth connection on start-up for no obvious reason and wondered whether anyone has finally come up with a cure for this. I used to think that it was because I had a USB-1 hub connected, but even after upgrading to USB-2 it still happens. Basically everything shuts down as per normal, but when I restart on some occasions I have no Bluetooth connection (squiggly line across icon). Luckily I only use my Bluetooth keyboard and using the wired mouse I just have to shutdown and restart and all is back to normal. However, I have no idea why this happens. I used to think that it was linked to using things plugged into the hub and the order in which I turned them off before shutting down, but it does it even when I've had a session when nothing plugged into the hub has been used. It's not a huge problem as a shutdown and restart sorts it out, but it would be more of a drag if I was using both Bluetooth keyboard and mouse and had no USB mouse.
Any ideas?

Neil, I have had the same problem, Apple informed me that they know about it, and the fix is simply to restart, as you have found out. The problem is intermittent, sometimes the Bluetooth icon disappears on restart, sometimes it's there. No rhyme nor reason, but just one of those quirks one has to live with. It has nothing to do with hubs or the like, it just happens.

Bluetooth lost connection

My apple mouse and Macally keyboard drop connection via bluetooth while being used. KB is difficult to connect. Clicking "connect" (Sys Pref/BT/Macally). Is there a problem with Imac and bluetooth?

I am running into the same issue. Ever since I updated my OS to Lion (now on 10.7.4), my iMac will periodically lose connection to all my Bl;ueTooth devices - Apple Wireless Mouse (Magic Mouse), Apple Wireless Keyboard, and Apple Wireless Trackpad.
Often happens after I don't use the Mac for a while and then I am trying to wake it up. (I can plug a Logitech Wireless mouse/keyboard into the USB port and I can use those, but I can not re-establish connection to the Apple wireless Keyboard, mouse, trackpad)
I have been able to re-establish connection after I reboot, however I never had this issue when I was on the pervious version of the OS.
I have a 24-inch iMac from 2008, 3.06 GHz Intel Core 2 Duo, 4 GB RAM.
Any ideas?

HT3887 My Bluetooth keyboard lost connectivity

I lost connectivity to my keyboard after restarting my Mac. I cannot type in my password. Any suggestions?

You can substitute almost any wired USB keyboard (does not need to be an Apple board). So if you have one laying around, or if you can borrow one, you can use it to enable your Bluetooth keyboard again.

Lost my bluetooth mouse connection twice this morning - why?

My iMac 21.5" bluetooth mouse lost its connection twice this morning. The 2nd time for a long time (like 5-10 minutes). The battery indicator is still showing 36%. During this time the bluetooth keyboard had no problems.
It was very frustrating! I should get a wired mouse as a backup!
But in the meantime, what generally causes a problem like this? It's certainly not a proximity issue.
Thanks,
doug

Of course you can't reset preferences, delete bluetooth and re-pair or do anything that requires using the mouse to do something as long as you don't have a working mouse.
I did change the batteries, but that didn't help either. It just seemed to eventually connect again.
I'll take a look at the link though. Thanks.

Go into the App Store, tap Updates, and at the top should appear Purchases. Hit the tab that says "Not on this iPhone" to download again

HT3224 I am new to Mac and started transferring data from my PC to my new Macbook Pro. Connection was lost once I started and now my Pro is stuck on the 'Transferring Information' screen. How do I get out of this screen to attempt the connection again?

II am new to Mac and was trying to transfer data from my PC to my new Macbook Pro. The connection was lost however and now my Pro is stuck on the 'Transferring you nformation' screen. How do I get out of this screen so I can attempt the connection again? Is it safe to force shut down of my Mac and will it still prompt me through all the setup process again?

Welcome to Apple Support Communities
If your Mac and PC are connected by Ethernet, unplug and plug that cable again. If not, you have to turn off the MacBook by holding the Power button.
In the next startup, try to transfer your files again. It's important not to interrupt the transfer process, because in most cases, you will stop it and you won't be able to resume it

Suddenly lost connection to my wifi and my phone can't find it again?

I was just using my iphone 4s normally and it suddenly lost connection to my home's wifi. I have been trying for hours, reset the wifi modem and turned it on and off, put my phone through recovery mode- the whole lot. Please help!!!

Howdy whitneyavon,
It sounds like you are unable to either connect to, or see your home Wi-Fi network. I would first, update your router, then reset your network settings. Assuming you restored from a backup, my thought is that the backed up network settings may need to be refreshed:
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Check your Bluetooth, do you have a bunch of stuff listed in there that you are no longer using?
Or another peripheral you stored away in a cabinet near by?

Bluetooth Mouse "Lost Connection"

I keep getting a "Lost Connection" message with my bluetooth mouse even though I have plenty of battery life left? Does anyone know why or what I can do? Thanks!

Steven,
I had the same symptom. I found that there was a problem with there not being enough pressure being applied by the metal strip inside the mouse cover to the switch next to the laser. It was intermittent enough that it would lose contact every so often, making the mouse think that it had been switched off.
Making a slight bend in the metal strip so as to keep more pressure on the switch seemed to solve the problem.

Lori,
I have the same mouse and have had similar problems. Interestingly, as I am typing now it is working but I have suffered through lost connections since purchasing it 1 month ago.
Recently, I have added it to my favourites in the BT set up. I have also forced a passkey. My instructions indicated that the key is 1234 but I found old documentation on the net that say 0000 is the passkey. The later worked to pair the unit however not sure it fixed anything.
I do find that if I keep it charged using the batteries that came with it and the USB cable it holds up longer. I give it a good 24 hour charge then unplug and mouse away.
Hope that helps, Chris

Ios 8.1.1 bluetooth drops connection with Honda Accord

My iPhone 6 with IOS 8.1.1, when paired with the audio system in my 2014 Honda Accord will drop the connection after 1 minute when using the AHA app. Also, when I use Bluetooth as the audio source in the car, it will recognize my iPhone, but ignores any request to select music from the phone. These functions worked earlier with my iPhone 4S and IOS7. Is there a temporary fix for these issues?

Similar to VroomVroom: I have iphone 5s, was on iOS7, went to iOS 8.1.2, and I didn't notice that I had lost a specific bluetooth connection: Garmin Smartlink - Live Traffic App. The Garmin Smartlink uses bluetooth to connect to the aftermarket Kenwood DNX891HD I have in my car, this comes with a Navigation GPS included. The Garmin Smartlink app (Live Traffic) provides immediate traffic updates if your city is covered, and my city Cincinati OH is covered. This was all working fine before I upgraded the iOS on the iphone 5S. I read another article related to "carkit" connections between iphones and car stereos (for both NAV and also hands-free) - here is the key point and my theory: Only ONE bluetooth connection can be supported at a time. In my case - the hands-free telephone (thru car microphone and car stereo speakers) works fine, and I believe this is also "shared" by Pandora App (from iphone to Kenwood). So, my theory is the iphone will not connect to the Kenwood for the Nav, since it is already connected to the Kenwood for the audio (Pandora and hands-free, I think these two "share" the same bluetooth connection, and I think the Smartlink connection is separate). I messed around this morning in the parking lot at work, and my attempts to "forget" and "pair" the iphone and Kenwood would continously start playing Pandora, but the Smartlink still will not connect (when it dis work, I would see a green circle with two cars on my Nav map screen, indicating the smartlink connection and also status of the traffic). My next test this afternoon will be to delete Pandora app on the phone, try forget / pair again and see if I can get Smartlink to work. If this works, I'll reinstall Pandora App and try to get it back as well. My past 24 hours of skimming articles (don't ya love the internet !) seems to indicate that I am not the only person with bluetooth problems due to the iOS 8.1.2 update....hey Apple...where's 8.1.3 to fix this ?

Apple Wireless Keyboard lost connection when "command+space" is pressed

Hi, my apple wireless keyboard lost connection when command and space key was pressed. it does not lost connection when other keys combination was pressed. Are there any people has the same problem with me?
I am using Emacs all the time, the command and space key is the default short cut for Mark in Emacs. It is constantly used in my daily work. The wireless keyboard does not lost connection always, but it does lost connection sometimes. I have observed every time it lost connection, the command + space was pressed. Really strange. Any advice?
I am using Macbook Pro 13inch Late 2012, OSX 10.9.1, and Apple Wireless Keyboard

Got the keyboard working again, here how incase it can help anyone else:
I borrowed a USB keyboard to allow me to get past the pasword login.
First I rang disk utitlity to repair any permissions. I opended up the app 'Bluetooth Setup Assistant' selected 'Keyboard' then I turned the keyboard 'on' so the green light is flashing' and then hit continue. At this point the keyboard appears in the listing of found items, hitting continue I am then given a unique pairing code. Enter this on the keyboard and hit 'Return' after a few seconds, the pairing is complete and by wireless keyboard is back and working again!

Mac mini issue:lost connectivity with the wireless keyboard

I lost connectivity with the wireless keyboard and I can't unlock the lock screen.What can i do?

Sometimes powering the keyboard off by holding in the power button on the right end of the battery box and then after ten of so seconds powering up again will reestablish the connection. Other than that forcing a reboot using the power switch on the mini should restore the connection unless thereis something else going on.
If this is a recurring problem try replacing the batteries with fresh ones. If this keyboard has been paired with another bluetooth device such as an iPad or another Mac, unpair it from the other device.
