I have a Lenovo yoga 730 and I have bios in legacy I have 64gb usb i use for booting to kali Linux installer along with a usb to Ethernet adapter that I’m not sure is compatible with kali and a tp-link tl wn722n WiFi Adapter I’m doing a sort of dual boot along windows which is on an internal 256gb SSD and booting kali on a 350gb external sata drive.
Whenever I boot to windows and plug in either adapter they have a LED signifying they have power well this is not the case when I boot to the kali Installer usb it doesn’t detect my adapters and no LED’s flash or turn on.
so I skip network hardware detection and skip network mirror and I get this janky install of kali works fine but have rainbow color lines appear randomly but then after I do apt-get dist-upgrade it runs I restart and I get a kali with no icons and everything is blue with white letters this happens even if I get a new iso and reflash. Though in this state and before dist-upgrade command the adapters work but even during install it confuses me how the boot usb gets power and ext drive.

please edit your post to include paragraphs and punctuation.
thank you.

A web search for "tl wn722n WiFi Adapter linux"reveals that this is a common issue. You might try the search and check out some of the articles.

One thing I have found is that many manufacturers of USB wireless and network adapters provide--er--inconsistent support of Linux.
