If you have a drill and a small bit, you can open up the external case's hole quite easily. It's an unfortunate task compared to the more universally sized options, but the trade-off is there if you want.
It indeed is something easily fixable. The one thing I dislike about wireless communication is that, besides relying on software that (hopefully correctly) implements scarily complex specifications, it uses invisible radio waves. For wired connections, you can see and touch the thing that connects your two devices. Thus they're much easier to troubleshoot.
