After some reading up and experiments, I seem to have identified the underlying causes :-(
The wireless interface in question, is [Cannon Point-LP CNVi wireless-AC., vendor intel. Version 30.] driver = iwlwifi I guess the issue is that they are not supported properly by any opensource driver, and that they require proprietary binary/non-redistributable drivers. Presumably, 'firmware-iwlwifi'. Ironically, I have not been able to test/fix it, BECAUSE I HAVE NO NETWORK ACCESS :-) This is a tragedy for linux. Network access, in 2021, is the floppy disk of the 2020 - if you have no network access, you have nothing. To resolve it, I instead tried a USB wifi-adapter on the laptop - TPLink AC600. Ubuntu listed it, but completely ignored it(?). At least, it didn't bring me any network either. For the actual state of default iwlwifi with the Cannon Point CNVI, it actually "works", for a few seconds, sometimes. Sometimes it will briefly activate the wifi adapter, browse available networks, and for a brief moment let me connect to and access a network, for 20-30 seconds. Then it breaks down, and doesn't respond again, before a reboot. So, it's not a bug, per se (depends - you COULD say the way iwlwifi breaks, is a bug. I would assume it intends to support the cannon wireless adapter.) Given that a proprietary/nonfree/binary driver presumably exists, that WOULD work (?). However, as a user experience, it is broken. My probable action is to give the laptop away to some friends/family who can install windows on it to get it to work, and I'll have to buy another different laptop, presumably one that there exists working linux drivers for :-(. This bug report should probably be closed, unless it should be counted as a bug report against iwlwifi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1911650 Title: builtin wifi not seen by 21.04-jan-13 on asus-ux433f To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-kernel-di-amd64-2.6/+bug/1911650/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
