Hotspotting via Pi on eduroam

Hello pi people!! I'm quite new to raspberry pi but I know some basics. I'm trying to get my pi to act as a wifi access point for my less smart devices (like an amazon echo) to connect to the internet, which for me is eduroam (I want to hotspot my devices through the pi, connected to eduroam). I currently have a simple qualcomm wifi stick plugged into my raspberry pi 3 model b, and I'm using dnsmasq, hostapd, and dhcpcd, without bridging but instead NAT stuff with masquerading because the bridge command told me I couldn't bridge wlan0 with wlan1. I've got two issues. First is when the pi turns on, both the internal wifi and the wifi stick (wlan0 and wlan1) connect to my university wifi and eduroam on startup, this breaks hostapd and prevents it from starting its hotspot, which only turns on when I manually disconnect from eduroam and restart hostapd (then the SSID is discoverable on my other devices) Second issue is that after doing this, my devices still can't connect, saying they couldn't find an IP. I can share all my .conf files on request.
