I was able to connect and pair the adapter and extender, but only a 2.4GHZ network is created, no 5.0GHZ network.  I've tried restting and doing again, but the same result. 

I still have a 5.0GHZ network to select from, but that is from my original modem/router, which is to weak a signal for much of my home. I've spent hours on TP-Link "chat" tech support, but they have not been helpful and there is no possibility of speaking to a tech via the phone. I'm very dissapointed with Tp-Link's product support!

Anyone know why I'm having this problem and how to resolve it? 

Thank you.
