Wasting time on these things is what I do. I sometimes take stuff like this, test it, make some notes and put it away to be used later if needed. Later I can just pull something off a shelf and start working with it rather than spending an hour to see if it works. Just a note with the IP address, password and other configutration can save a lot of time later.
This device did not hold any special interest to me but it could be configured as AP, client, bridge so it might have come in handy one day. Especially when some friend calls me with some issue and I can set something up with elements that I have in my junk pile.
I have a lot of devices that are really of little or no interest and economically worthless but can one day get me out of a bind. Routers with Chinese menus, ADSL routers, etc. I have given away ADSL routers after installing them as switch+AP. They have no monetary value but can still have some use.
I have used AP + client to avoid drilling a hole in a wall. That kind of thing.
So, yes, I know what I am doing. I am wasting time in an enjoyable way.
