Bluetooth connection nightmare

It will be inconvenient, but you can try a fresh mavericks install. There was reportedly a problem with the initial mavericks upload to the App Store that caused a Bluetooth problem. But it doesn't really sound like your symptoms. If you didn't download mavericks early on or haven't been having this problem all along then that's likely not it.

Another test would be to boot to the recovery partition or some other boot disk and see if the issue occurs. If not, then it's likely a software issue and the above mentioned fresh install may solve it for you. If it does recur, then it may be some kind of hardware issue.

It sounds like you have a 2013, so it should still be under warranty. Take it in to an apple store or authorized repair center to take a look if you don't feel like messing around with it yourself.

 

Have you tried moving your 2.4 wifi channel to 1 or 11? I had issues with channel 6. Once I switched everything was fixed. Try any combination of 1, 6, or 11 and see if that helps.

 

Also try moving to 5ghz if you don't have large area to cover.

 

Instructions will be in your router's manual. Usually under the wifi settings once you log into the device.

 

Guys, this is a bluetooth problem, not a wifi problem.

Unless your suggesting that his wifi might be interfering with Bluetooth, but I don't think that's a thing.

 

I am aware that this is a bluetooth problem not a wifi one. But there is nothing from his post that would completely rule out wifi interference as a possible cause of the problem.

To OP: Have you ever paired your bluetooth devices to other Macs? Or are there any other Macs around where are using iMac? I had some strange issues at my work that caused issue with Magic Mouse. It would randomly disconnect and connect to fellow worker's machine because Magic Mouse was paired with his machine at some point in the past. We fixed it by deleting my Magic Mouse off of his bluetooth settings.

 

I am well aware the OP posted about a bluetooth issue because I read the OP's question and answered with my anecdotal experience with bluetooth and wifi interference.

If I change my Apple Extreme's 2.4 band to channel 6, my BT keyboard and trackpad begin to lag both with movement and input. Both devices also disconnect at seemingly random times. It gets worse as the CPU load increases. When on 1 or 11, no problems whatsoever.

I found the solution to my problem by using Google and reading one of the solutions posted in https://discussions.apple.com/message/12976433. There are four other threads with this same problem, all fixed by changing the channel of the router, that I just found in under a minute. This is a well documented issue and worth a try since nothing else has panned out.

OP, we don't know what type of router you're using or the Wifi settings. Some routers have an auto channel setting, where it looks for the least amount of interference and adjusts accordingly. Maybe a new neighbor moved in and started crowding the channel you were on and the equipment changed channels automatically, thus causing a problem.

That's the beauty of forums, free advice for issues you may not have thought about.

 

Tulani...Check the model number of your router (probably on the back) and download a copy of the manual. Inside you'll find instructions for making changes to your router's settings. You'll need to log into the router to do this.

Have a look through the link/thread I posted above. You may need to change the channel or possible change the g/n broadcasting of the router.

Good luck. And remember, it's just an idea to help you out....doesn't work for everyone.
