I thought that most modern devices understand the difference between an encrypted AC and a non encrypted one and will not automatically connect to an unencrypted one. I'll let the more experienced experts comment, but I thought that's the way they behave.

No problems here. Works 100% Are you sure you're supplying enough power? The Nano will act wonky if there's not enough power going to it

Are you using the "Y" cable to power it and does your USB hub have enough power?? I had the same issue when I realized that my USB was NOT providing enough power. Once I switch USB hubs, everything worked fine.

I had the exact same problem. I first finger tightened them down and observed as you all did, that these do not 'locl' and the antenna rotates very freely. Then I simply used my leatherman pliers to tighten them down ~1 full turn Past finger tight. (I was hoping I would not crack the case nor strip the threads.) All worked fine. Antennas are very tight now. Although removing them, if I need too, will require that leatherman again :)
