Sometimes Clients and Blue Curve don't always pick the best pod or router to connect to. For the most part all my devices, after a few days, get things sorted out connecting to the best pod or router. My iPad 11 has had a challenge connecting to the correct device as I move around the house. Mainly letting go of the slower pod when I am back in the main room of the house where the 6E router is. The result is slower speeds. I eventually deleted the client and started again. Forcing the correct router connection. 

I hope with updates this problem will settle down.
