We have only been testing with E303 and we had one of them, which got
plugged into a Windows machine. After that it didn't want to autoconnect
any more, until we did a "restore factory defaults" or "reset" on it's
web server. After that it worked fine again.

Well, HiLink is a pretty ugly design in any case. E.g. you will run into
problems when you want to use yourself on another
interface. Problem is that some have these sticks and want to use them.

If really necessary, this "hilink protocol" could be the place to add
these ugly hacks...

Thats certainly possible, allthough I'd be interested if the "reset" as
described above helps. And we all do DHCP or use an IP from the range, no?
