A problem about web connection of my Linux computer

Ubuntu

1

I recently installed Edubuntu on my Acer laptop :laptop: and erased all data of Windows 11. I have been unable to connect to the Wi-Fi :wireless:since I installed it. The problem exists even though I have turned off the quick start and secure boot. Now I can only access the internet :globe_with_meridians:with wired connection. How can I solve this problem :thinking:
My laptop 's structure is AMD64.

I don’t know how Edubuntu works. Never tried it. But isn’t Ubuntu asking for enabling repositories for specific drivers when installing? Maybe this is the same in Edubuntu? :thinking:

Edubuntu is a distribution of Ubuntu for education. More educational applications is the only difference between Ubuntu and Edubuntu.

@zreamer Found this link, https://forums.linuxmint.com/viewtopic.php?t=467205 a post by JeremyB, who is very knowledgeable about wifi on Linux. His suggestion:

sudo apt install git dkms
git clone https://github.com/hmtheboy154/mt7902
cd mt7902
sudo make install_fw
sudo dkms add .
sudo dkms install mt7902e/git

If you review postings in the old Ubuntu MATE Discourse site, you will soon determine that suggestions from Pavlos are solid.


Golden rule is always boot from Live Distro image, before installing, to confirm compatibility and availability of all necessary drivers and sofware.


Decision Point:

  • If all is good from Live Distro, proceed with install.
    (Success may require additional packages to be installed, but working state at Live indicates all necessary is obtainable, just might not be installed.)

  • If all is NOT good from Live Distro, do NOT proceed with install.
    (Install will not succeed because the hardware database or compatible packages are not available, otherwise the Live Distro test run would have been successful.)


Post-Install Troubleshooting:

When you boot from the Live Distro image, not the installed Linux image, can you confirm using a browser that you have

  • internet access (wired)?
  • internet access (wireless)?

Need to know both states because it helps to pinpoint where the networking “connection” is broken.

If both states are available from Live Distro, boot to installed Linux and again verify using a browser that you have

  • internet access (wired)?
  • internet access (wireless)?
