It works now. Here are the steps I took to get everything working in my laptop:

1. use ethernet or usb dongle to connect.
2. install ukuu kernel update utility.
3. update kernel to 4.15.2
4. Reboot
5. Download and build rtlwifi_next

Code: Select all

sudo apt-get update
sudo apt-get install git build-essential linux-headers-generic dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

6. Download rtl8822befw from https://github.com/rtlwifi-linux/rtlwif ... re/rtlwifi

Code: Select all

sudo cp ~/Downloads/rtl8822befw /lib/firmware/rtlwifi

7. Reboot.

This fixed not just the wifi, but other components like touch pad as well.

Do you really need UKUU and the 4.15 kernel to use the lwfinger github?

With Linux Mint 19, everything is working, except the Wifi, given, the open source driver is not stable and freezes and restarts, I bought this:
https://ark.intel.com/products/99445/In ... ss-AC-9260

It is kind of cheap and at least, it is capable 1.73GB and MU-MIMO and they say, no freezes will be. Until, I receive, I am stuck on wired for now, but at least, with M.2 half height PCIX SSD, 34 GB RAM 2400 Mhz, it is awesome.

I just do not know on Linux with RYZEN 1700 go to to boost. I can go up to 3.2 Ghz, but not 3.7. Of course, on Windows it works everything perfect.

Kind of new Laptop ... I am sure, we will reach 3.7 Ghz on Linux Mint 19 Laptop as well... Hopefully!

Ciao!

Hi Aeronex

I have tried your solution on my new Ideapad 530S Mint 19. I have the RT8822BE wireless card and it says it is unavailable

I got to this point in your code -

sudo dkms add ./rtlwifi_new and got this error --
Error! Could not find module source directory.
Directory: /usr/src/.-rtlwifi_new does not exist.

Any suggestions greatly appreciated
Regards

Did you copy the downloaded file to: /lib/firmware/rtlwifi/ ?
Copy: sudo cp ~/Downloads/rtl8822befw.bin /lib/firmware/rtlwifi/ (Step 6).
Then build (Step 5).
Maybe that will help.

[wosco]

No I hadn't but after downloading and copying file I still get the same message

[wosco]

I found the problem and completed the installation, it is on kernel 4.15.0-39-generic/x86_64, rebooted but it is still not recognisable

Any ideas?

Thanks
