After some updates, wifi of this poor laptop down again. Check the err msg "RX_FLAG_40MHZ" undeclared, we find Possible issue with new kernels #247, so instead of the original git address, using
git clone https://github.com/synthtc/rtlwifi-next
Same steps after that, build and install. Make sure that your system is up-to-date then proceed. Hope this driver problem can be solved by official release soon..
if you have met the following err msg
error: ‘NUM_NL80211_BANDS’ undeclared here (not in a function)
check this link and we got
The second can't compile without making a little change in the source code. The change is to add the line
----in wifi.h after
---in base.c before #include lines
Seems this is a very common problem. After my fresh installation, good thing is that Nvidia did not give me much problem.
This is time goes to WiFi...
Some people suggest if no wifi when PC awake from hibernation, We could simply restart it.
This definitely doesn't work for my case.
Firstly, we need to find out our more details of our wifi adapter.
sudo lshw -class network
Product and vendor: Realtek Semiconductor Co., Ltd. So we should google for corresponding solutions. Skip the post or videos working on Broadcom problems. Because in my Software & Updates dialogue, the Additional Drivers tab, there is no Broadcom items. In my case, only Unknown besides Nvidia.
If your Realtek adapter is rtl8723be, you could follow the steps shown in the video. I tried to follow the steps also.
If you execute
command not found. Try to install aircrack. Mentioned in the comments.
sudo apt-get install aircrack-ng
Then problem comes. when execute suds arimon-ng, It does not give me any info. Login to windows and checked the type of my realtek is rtl8822be, from the official website we know that this is a 802.11ac/abgn PCIe WLAN with Bluetooth 4.1 Single-Chip Controller.
ubuntu 16.04 + "rtl8822" + driver
This time the results are not so off the target.
So excited that someone has the same problem on the same brand new HP omen..
Hints from the comments that I should upgrade the linux firmware.
Check this page
Ok, it mentioned that
rtl_bt: Add firmware and config file for RTL8822BELets download the .deb and install...
seems the blue tooth is working now but nothing happens to the wifi -_-!
Install linux firmware 1.167, still no wifi.. So do not know what to do and stops here.. waiting for the new official updates.
