Hi again, folks. I haven't tried the WiFi Locker yet, but will check it out. Before trying to connect, I did make sure WiFi was enabled, connected to my hotspot, and checked the IP address.
The router is a D-Link, and I think by default they don't allow different devices on the WLAN to talk to one another. I have a Linksys router in storage, so I might get that and give it a try tomorrow. Thanks again.
