No networking available for Live ISO - Installed ISO has networking as expected

Pre-Release Discussion

I’ve recently installed the UM 26.04 LTS Resolute Racoon Daily Build from Nov 19 2025.

lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=26.04
DISTRIB_CODENAME=resolute
DISTRIB_DESCRIPTION="Ubuntu Resolute Raccoon (development branch)"

Instead of repeating myself, I hope you don’t mind my redirecting you to the UbuntuMATE Community Discourse forum where I have posted details about this issue.

Thank you.

It would be better if you provided details on this site, rather than link to elsewhere, especially if you want to give attention to an issue.

The report_inxi_Fza.txt on the Ubuntu MATE discourse shows a 6.17 kernel for starters, yet a quick look at the current manifest for the daily shows

linux-image-6.18.0-8-generic	6.18.0-8.8
linux-image-generic	6.18.0-8.8

but you do mention an older ISO??

Why not try a current ISO? eg. when I went to compare the kernel details of your pasted details with what I expected, I looked at the 20251228 ISO

I suggest you re-test using a current rather than daily from over a month ago.

Later addition: I used the daily as you mentioned the daily build in your initial text. If you were limiting yourself to officially released snaphots your ISO is still old, as Snapshot 2 for Ubuntu MATE resolute can be found at Ubuntu MATE 26.04 LTS (Resolute Raccoon) having an ISO of 20251209 which is older than the daily I used earlier, but it’s still much newer than your old ISO (but monthly snapshots are older than dailies)

I’ll close this thread as the ISO used is just so old.

@ericmarceau if you test a current ISO and have the same issue, send a PM to moderators or myself and we can re-open this thread… but a lot has changed from your much older ISO.

(To me [personally], any daily [ISO] that’s older than the latest Snapshot is of no value, unless exploring when a regression occurred on later/modern ISOs)
