  • 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 ](https://askubuntu.com/questions/1305699/bcmwl-kernel-source-broken-on-kernel-5-8-0-34-generic#1305819) 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
