The other day I fell asleep and left an unfinished beer on my laptop that I was attempting to install 15.2. Woke to find it fried. No power at all. The hard drives went long ago but this thing was able to run suse from 10,3 to leap 15.1. Had that laptop for about 8 years. It had many lives. Anyhow I bought a HP All in one. It has a Realtek wireless adapter and it would not work while I was installing 15.2 on an external usb drive. NO WIFI. I did come to find out that the driver at this link
will correct the problem. But only if you download it. Extract it. Could not install it with yast. Rename it to rtl8821ae. And put it in /lib/modules/5.3.18-lp152.19-default/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8821ae/. run modprobe rtl8821ae. AND IT FREAKEN WORKS. Hope this helps someone from going thru what I went thru in the last couple of days.

EDIT There were 5 different people on that site. I was trying to install each one with yast but each one was failing. But the solution happened with one of them. I think I posted the right one. But I'm not sure. One or all of them do work. If you extract them, and copy to the above folder.
