Boy , another update already ... cool . Updating now .
Much thanks Skello . 
I'll report back my findings .
I am also seeing random disconnects on my C1 set as a wireless bridge with the 14594 version. I have reported the issue on the dd-wrt forum and got some suggestions for settings, but it is still happening, although it has been > 1 day since I had to unplug the bridge. Letting it soak a while to see if it stays up.
Reporting back on my C1 ... unfortunately same status for me still even with the new version ; unknown random disconnects as before . Tried various settings again all N speed (no mixed mode being used) Again tried 20/40 , 40 , differant anttena settings , the whole gambit possibilities , etc .
Funny thing is , once a disconnect has happened and the router is powered down and back up and I
USE the connection , Iam fine for the whole time Iam using the connection ; its when the connection is
NOT being used (sits idle) is when the disconnect happens at some point .
One thing Ive noticed too (maybe my lack of using "bridge" knowledge) , but I can only use channel 11 , there no other options/channels available as in say in a normal router or AP mode . I know 20/40 or 40 limits you in that reguard ; just was surprised that only one channel shows in bridge mode (normal ?) , as my 655 gives me afew channel options in those modes .
