I was both hunky and dorey with having a wide-open wireless router when it didn’t affect anything. Sure, drop on by and leech my bandwidth. I’m obviously not using it, so why shouldn’t someone else? It’s the friendly thing to do.
Then the neighborhood leeches started to affect my ability to stream music from my server. The party was instantly over.
It took a long-overdue firmware upgrade but now my wireless router is locked down to accepting connections from just four MAC addresses. All others are promptly shown the door. Sorry, but that’s just the way it has to be.
Don’t. Mess. With. My. Music.
