The other day I updated my system from Mac OS X 10.5 to 10.5.1 and ever since my Apple Wireless Keyboard has been randomly disconnecting and reconnecting every few minutes. I have tried changing the batteries, resetting the keyboard, repairing, etc. but am still having the same issues. I hit up the Apple Support Discussions and found hundreds of other users reporting the same problem and I am convinced that this is an issue caused by the last software update.
After some testing on my own to see what I could do to fix the problem I have come to the conclusion that there is some interference from the bluetooth connection and my Airport connection. After disabling my airport and using the wired connection for hours I have had no problems.
Apple, please get this issue resolved soon. I don’t like being all tangled up in wires.
UPDATE: Just wanted to give everyone an update on how I fixed the issue. I found that I have a new wireless network in my area now, which I believe was set to the same channel as my router. I went into my router settings and changed my wireless channel from 6 to 9 and applied the change. I haven’t had a problem since. Apple suggested that I buy a Airport basestation because it supports more then the 2.4GHz spectrum. This would also fix my problem, but for $200.
