Problems with wifi hotspot. With wpa personal doesn't ask for pw and speed is dismal.

I have two problems. I am attempting to run a x86 computer as a hotspot. I have a T-Mobile hotspot (slightly broken) connected via a usb cable. I get >100 Mbps with a 5G connection. Great! so I attempted to turn my wifi port into an AP. That almost worked except for a couple of problems. I used the network manager to configure it and I was able to then connect to that wifi connection from a couple of devices. The first problem was that it never asked me for a password. I happily connected up right off. The second problem was that it was slooooow. It started at about 3 Mbps and went up to a whopping 4.7 Mbps. Granted this isn't a big box, but it's not bad either. I also have a AT&T hotspot that is getting about 8 Mpbs, which isn't great either but better than the T-Mobile connection.

Questions are, should I be getting better speeds? If so what might I have to tweek?

How do I get the connection to be secure? Here's part of the nmc file:
