Please [edit] your question and add output of lspci -knn | grep Net -A3; uname -r terminal command. – Pilot6 Jan 09 '21 at 14:59
I have added the output for the command " lspci -knn | grep Net -A3; uname -r " – ABDERRAHMANE OUALI Jan 09 '21 at 15:15
This is a known issue with the new kernel. – Pilot6 Jan 09 '21 at 15:17
the other answer on the question suggest bcmwl-kernel-source broken on kernel: 5.8.0-34-generic that remove the following package linux-generic-hwe-20.04 linux-image-generic-hwe-20.04 linux-headers-generic-hwe-20.04 but it give me that error E: Sub-process /usr/bin/dpkg returned an error code (1) – ABDERRAHMANE OUALI Jan 09 '21 at 15:28
The easiest is the first option. Download the deb and install in using dpkg -i bcmwl..... – Pilot6 Jan 09 '21 at 15:29
