TL-WN722N V4(rev4) Compatibility Issue with OpenWrt
Dear OpenWrt Community,
I am currently experiencing compatibility issues with the TP-Link TL-WN722N V4 USB WiFi adapter on OpenWrt. Despite efforts to install and configure the necessary drivers and packages, the adapter does not function correctly. It fails to appear in the output of iw list, indicating a problem with driver recognition or support.
After attempting various troubleshooting steps, including driver installations and updates, the issue persists. It seems that the necessary drivers or firmware for TL-WN722N V4 may not be fully supported or integrated into the OpenWrt kernel.
If anyone has successfully resolved this issue or has any suggestions on how to achieve compatibility with TL-WN722N V4 on OpenWrt, your assistance would be greatly appreciated.

search the forum for 2357:010c, but RTL wifi adapters are usually highly discouraged.
upgrading to a kernel 6.6 based snapshot might help, but not very likely, since this hw is ancient.
