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:

Code:

[connection]
id=Wi-Fi connection 1
uuid=f931852c-75f8-472e-b146-4058a45276d7

Before anyone asks why I don't just connect to the T-Mobile hotspot wifi directly, it's because I can't. One of the screens on the device lists the ssid and pw, but when you connect to it, it says "incorrect password". I even looked at it with a magnifying glass and I am sure it is right. Even though the first character could be a capital "B" or a number 8 (fuzzy display) I tried both and neither worked. There was some strange kerning around the 5th (?) letter but I didn't know what to make of it. It kinda looked like there was a half space before and after that small letter "s". Anyway when I tether the hotspot using an USB cable, I get a connection on 192.168.1/24 and browsing to 192.168.1.1 connects but gives no output so I can't get to the admin pages to reset the password. Instruction on one of the displays on the hotspot says to connect to http://mobile.hotspot but that just times out and ends up with a google search for mobile.hotspot.

@Jim44

I am showing my stupidity, which I can do very easily.
In the information you provided do not see an actual wifi adapter listed in your information. What make model of wifi card is in your machine
Have recently been down this rabbit hole with two Debian Bookworm upgrades,,, after being very rusty,,,thank God,, at having to do any fixups on these boxes prior to an OS upgrade.
