Hi all - just thought I would post something I have found fixes (for me) the problem with repeated deauths dropping my wireless connection. These appear in the logs like this:
Wireless system with MAC address XXXXXXXXXX disconnected for reason: Received Deauthentication
Note: I am on a Macbook Pro, Intel 2.4gHz Core 2 Duo model, with wireless N "airport" card. Router is set up to used mixed N, G, B modes, allowing router to scan for best frequency, hidden SSID, WPA/WPA2 with PSK, both TKIP and AES enabled. So - this may be a Mac-only solution, dunno.
I know other people have had this problem, and since I have now had the same solution work for me twice, I feel I should share this. I just wish when it happened the 2nd time I remembered more quickly what the problem had been the first time, would have saved me a few days.
Basically, it is the RealPlayer download helper. It's a piece of software that runs in the background. When you view a web site with an embedded flash movie, it downloads it automatically and allows you to save it. The download helper gets installed automatically when you install RealPlayer, and it doesn't show up on the bar with other running programs until it gets activated. You can kill it on the Mac through the Activity Monitor (kind of like the Task List on Windows, more like a process list on Unix). To keep it from being a problem, you need to prevent it from loading at all. On the Mac, this is done in the System Preferences, Accounts, Login Items. Select it and click the "-" button under the list to delete it from the startup items.
I am a long time computer user, and I am a network analyst by profession with many years experience. I have absolutely no clue why this particular piece of software causes this issue, and it doesn't make any logical sense. But I DO know that kill it has cleared the problem for me - as I said, twice now. Perhaps even for other users, other OSs, other pieces of software running in the background could also be a culprit.
Hope this saves someone some grief.
