Poor WiFi connection after updating Linux Mint 18.3 - Solved

Post by TimWS » Mon Aug 27, 2018 10:10 am

For the last few months I’ve been using a HP Stream laptop with Linux Mint 18.3 as the only Operating System.
After a recent update I’ve lost WiFi connection if I boot up using the latest version of Linux: Linux Mint 18.3 Cinnamon 64-bit with Linux 4.15.0-33 generic. I get my normal WiFi connection if I boot up with an older version (with Linux 4.15.0-32 generic) using advanced options.
I’m aware of the WiFi connectivity problems caused by the single antenna in the Realtek RTL8723BE which I thought was cured using some code I found in another post and if I try using:
Sudo modprobe -r rtl8723be
Sudo modprobe -v rtl8723be ant_sel=2
It makes no difference so I think it may be a different problem.
Can anyone help?

Do

Code: Select all

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new
cd rtlwifi_new
make
sudo make install
Then reboot
If the next kernel isn't fixed do

Code: Select all

cd rtlwifi_new
make clean
make
sudo make install
Reboot

Thanks. I gave it a try but after the second command I got the following error:
fatal: unable to access https://github/com/lwfinger/rtlwifi_new’ : Failed to connect to github port 443: Connection times out
I’ll reboot and try again

Perhaps there’s a problem with the github website. Unless someone has a better idea I’ll try again tomorrow.
Thanks anyway.

Reboot into an older kernel and run the git clone command, then boot into the -33 kernel and run the rest

I tried:
git clone https://github.com/lwfinger/rtlwifi_new
Instead of:
git clone https://github/com/lwfinger/rtlwifi_new
And it has worked.
Thank you very much for your help Jeremy.
