How configure an time to avoid the system to disconnect my wifi connection ?

Thanks for reply.

What kernel module are you using? If it’s iwlwifi look elsewhere on this forum for the answer. It was recent, too.

Kernel 5.4.0-42 32 bits

That’s the kernel version, not the kernel module that is essentially the device driver for your wifi chip. I’m looking for a name, not a version number.

@aug7744 Try the following:

Internal cards

To identify a card that was installed inside your computer prior to purchase, please open a Terminal and execute:

lspci -vvnn | grep -A 9 Network

This will display:

You now know:

  • The PCI-ID: 14e4:4331
  • Kernel driver in use: wl


Something that might help you… Lubuntu is basically Ubuntu with a different skin (some will argue but think of it like that for now). When you run into issues, you can just Google your problem and if anything related to Ubuntu has a topic on it, you can look into it and you may find an answer. Also feel free to search on this forum as well before making new posts. You might find someone already had your problem.

Tangent: pretty sure lsmod command would’ve shown something too but I just copy/pasted the first thing I found.The above will at least tell you what module you’re using. :wink:
