Steve, are you running any of your e4200's as bridges?
I've now flashed to the recommended kingkong-nv60k-broadcom-22000M.bin, and all of the issues in my above post are the same. And for the heck of it, I did a 30-30-30 before flashing, after flashing. And then for good measure I flashed the same version again followed by a 30-30-30. wl1 on the bridge will not keep the selected channel. And every attempt to change it causes wl0 or wl1 to change. It's maddening.
23040 is affected by the heartbleed if you are running the openvpn/mega version.
*Sigh*, so should we upgrade now to unstable version to avoid the heartbleed ?
