I've been following a tutorial at https://www.makeuseof.com/tag/raspberry-pi-vpn-travel-router/ to try to turn a raspberry pi zero w and a TP-LINK TL-WN722N(v2) WiFi adapter into a vpn hotspot, for use with open networks when travelling.
the use of a semi non-standard "router" has posed a few issues, but I've gotten around and fixed them, and am now trying to set up my adapter. It is known to work well on raspbian, and I have in fact gotten it to work on my Pi 3B and 4B. I have an adequate power supply for it, and current draw should not be an issue. However, plugging it in sometimes triggers a restart. More importantly, despite installing "rtl8188eu-firmware" and the device showing up in lsusb, wlan1 isn't found if I run ifconfig.
I am not that much of a newbie with linux, but have managed to stay away from compiling drivers due to good support. However, this is only my second time using openWRT, so I am somewhat lost.
If someone could tell me why my adapter is not working and how to fix it, or even that it is not supported and to buy a new one, that would be great. however, I would ideally like to avoid buying an adapter with better support because I am short on cash and where's the fun in that?
Thank you in advance.
