I bought a new laptop (Lenovo legion G5) I installed windows & ubuntu in dual boot. On windows side my wireless adapter work as well, but on Ubuntu I got this message : No wifi adapter found.

I tried many solutions, I found this one wich is very similar to my laptop specs, but unfortunately when I execute this command :

cd rtw89 && make && sudo make install

I got an error message :

cp: cannot stat 'rtl8852au*.bin': No such file or directory

sudo lshw -C network

Ah, haa! You have a probably conflicting driver loaded. Please do: `sudo apt purge bcmwl-kernel-source`, reboot and show me a new dmesg.

With the ethernet connected, try: `cd rtw89` and: `make clean` and: `git pull` and: `make` finally: `sudo make install` Any improvement after a reboot? Reference: https://github.com/lwfinger/rtw89/issues/76

I have followed your steps : [here](https://ubuntuforums.org/showthread.php?t=2464841&p=14048367#post14048367). Now when I `sudo make install` I have this message `Install rtw89 SUCCESS` After a reboot my wifi still does not work. Command `sudo modprobe rtw89pci` return this error message `modprobe: ERROR: could not insert 'rtw89pci': Invalid argument`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
