I used my XR-18 based system for a parking lot party over the weekend. I have the mixer mounted in a rack with a my Furman PL-Plus and a rack drawer, and a Netgear router installed in the back. I never use the internal WiFi of the XR-18. I always have my laptop along for primary mixer control. I set it on top of the rack and connect to the Netgear network, and boot right up. No issues. My Netgear network is password protected and always works flawlessly for connecting to the mixer. What I never considered the possibility that my *laptop* might choose to connect to a different network! Turns out that the building beside the parking lot had a strong open network that didn't require any password to join. At one point during a band's set, my laptop decided to hop on that network, which meant that it was disconnected from the mixer. The singer went to start singing a song, and nothing came out of the mic. ARRRRHGH! It only took me a second to figure out what was going on, but then I had to get back on the right network and reconnect with the mixer to get the sound happening again. I was impressed with the poise of the very young band...they just kept jamming on the intro until I told them the PA was back up, and they went right into the song without a hitch. But what a surprising and embarrassing situation for me. I had an ethernet cable in my drawer, so the first thing I did was hard connect my laptop to the router. That will be my first move each and every time I use my system in the future. Then I went to the network preferences and moved the Netgear network all the way to the top. I deleted the other network to prevent a reconnect. I made sure that my computer should prompt me before changing networks, and that ethernet connections were always prioritized over WiFi. **** FWIW I'm still amazed by what a small, portable system is capable of doing circa 2017. I sold my sub and tops last year after I quit the band I was in, but I kept my XR-18 rack and three K-10's so I'd still have a small system. I used my K-10's as monitors and rented three EV ZLX12's from a buddy and ran two on sticks and one in front of the center of the stage. I'm not a fan of the ZLX's but they did the smallish job pretty well. We weren't trying to throw sound a hundred feet or anything, and as long as you stayed near the stage area the sound was balanced and clear. Not having a sub isn't ideal, but this event isn't a concert, it's a chili tasting with some music off to the side. I volunteer my gear and services so the event can raise more money. This little video I took of a kid dancing doesn't have any vocal content but at least you can hear the band mix. This was shot from my side-stage mix position, I wasn't even out front.
