I've been using the SA520W for a few months now and just yesterday had shipped in an AP541N. Expecting that the device would share a common interface, I wasn't disappointed. However once I got into the menus a bit more, I began to see that in many ways, the AP541N is a step behind on basic features than the sa520W. I mean features that I would think should be common to call Small Business Pro products.
Example: The device login password has a limit of 8 characters. And, you can't change the default username from "cisco" to anything else. Why not have these types of features be the same as the SA520W? I know there may be differences in memory size or what not, but 8 characters? Does anybody know if stuff like this is on the list of things to improve on?
it's not the end of the world, but not being able to change the username makes hacking the device pretty easy as there doesn't seem to be any lockout mechanism either (or at least not after 9 tries).
it's a nice product otherwise though, haven't actually used it yet but we'll see.
