Just upgraded this morning from 6.1 to 6.2, I don’t have had the boot problems I have read elsewhere, but I got any network interface not working anymore.
I have had the mobo Eth (getting problems years ago so never used again), a Eth PCIe card (TP-link TG-3468) and an USB stick wifi (Archer T4U v2) all not working anymore.
Not an expert I’m just a user since some years, with latest changes where Discover update only to next and not directly to latest release (using my dual boot PC remotelly I often don’t update for weeks if not months) all seemed more reliable.
Downloaded the linux drivers (from my laptop) of the pcie card and usb wifi stick seems I’m not able to complile them due I don’t have the modules needed to compile kernel modules.
There is a way to setup this needed modules downloading them from my laptop, passing to my pc and installing them.
Or maybe there is some faster way to solve the problem.
Doing “dpkg | grep dkms” find a rtl8812au-dkms, that seems to be installed but not loaded.
Doing “sudo modprobe 8812au” return “modprobe: FATAL: Module 8812au not found in directory /lib/modules/6.8.0-49-generic”
Note: got these commands suggested from AI, have no clue what they are meaning.
The system report I’m still on 22.04, but is using kernel 6.8.0-49-generic, as far I understand used on 24.04 that needed to be the upgrade target.
Trying to boot on kernel 6.5 result in an error.
Without network I can’t update anything, will be happy for any suggestion how to proceed.
Further investigating seems
- Archer T4U v2 usb wifi has a too outdated Linux driver, impossible to compile using the provided makefile. Trying this alternative solution posted in the thread “Ubuntu Driver WLAN TP-Link Archer T3U Plus and T4U for Ubuntu 22.04 LTS Jammy Jellyfish” on tp-link Home network community generate errors trying the modprobe path, using dkms seems to reach the end but give errors trying to load the driver in the kernel
- TP-link TG-3468 seems to don’t have a driver working with 22.04, or at least I wasn’t able to find a solution in current setup. Funny it was working with Neon 6.1, that still use 22.04. I suppose the new kernel broke the compatibility
- testing the motherboard internal eth interface this is active (green led flashing), but seems there is no way to activate an internet connection on it (NetworkManager was disabled, but enabling it and trying to get up a connection result in an error), it uses a Realtek RTL8111 controller that has probably either not suitable driver for the 6.8 kernel
In the end the only solution I found so far was trying again to boot on kernel 6.5 and this time worked: I got back the wired internet connection.
Trying to complete the 6.2 updates don’t solve previous problems, and so far I have not tested the 24.04 upgrade (will leave this for next year, too busy now), nor tested if under 6.5 also the other network interface are working.
Still 1.5 days lost in this problems, KDE Neon as much I like the uptodate desktop is more and more pushing me switching to Kubuntu, if I only will have the occasion to.
