Unable to connect laptop via wifi after install completes on lubuntu 20.04LTS


Borrowed from a post on askubuntu.com originally written for lubuntu19.04 but works for new 20.04 LTS also...
NOTE: you will need a android phone that supports tethering effectively!

Though its been long and many years since this question is posted, yet i find it meaningful to add my experience of facing the same issue with latest lubuntu version ie. 19.04. After installing lubuntu 19.04, i noticed there is no way to configure wifi connection. Network manager was not listed. There were some of posts which points to download and install driver, but how exactly you can download driver when you dont have internet connection at all. At last i followed below steps which helped me to get rid of problem-
  1. You have to provide internet connection to your system in some way. Either use lan cable to connect to broadband modem or use your smart phone's internet.
  2. I used my android phone. connected through usb cable to my laptop. After connection go to cell phone -- settings --> Network & Internet --> Hotspot and Tethering --> USB Tethering. Turn it on.
  3. As soon as I turned it on, my laptop running on lubuntu started displaying available wifi networks. i could then connect to my wifi network (it just demanded for wifi password). Lubuntu was using the network support from android device tethering. The problem is not yet solved! If you disconnect your cell phone or switch off tethering, lubuntu laptop will again loose the internet. So you need to install the drivers now to resolve it permanently.
  4. In your Lubuntu go to Start --> Preferences --> Additional Drivers . Enter you password if asked for. It will open Software Sources. Go to 'Ubuntu Software' tab. Make sure all options are checked. Source code you can ignore. Next when you click 'close', it will prompt to upgrade the outdated drivers. Click ok and continue. Let system install new drivers. Let it complete.
  5. After completion of driver downloads, go to Preferences. You should see Advance Network Configuration' available now. You can disconnect your cell phone now! Internet would continue working fine on you lubuntu system.


Notes
1. Several typos corrected from original(askubuntu.com) version.
2. In my reflashed chromebook application the step four above did nothing as there never were any windows style drivers for this device. What fixed the wifi was the update process from the version installed to current patch level I believe.


Hope it helps!

  1. I have since abandoned ubuntu completely and resigned myself to the wonderful (relatively) world of debian distros.
