I have a machine with duel boot

windows loads network perfectly

ubuntustudio 22.04.1 LTS Don't

however I could use sudo netdiscover to see my router ip

browsers can't open it's page or surfe the internet

ping gives network unreachable with IPs and temporary failer in name resolution with domains

network manager is keeping attaching and deattaching network with IP configuration was unavailable

enter image description here

enter image description here

  • I tried reseting router and no efect

  • then tried re-installing ubuntu however I noticed that the network have the same behavior from the live session _

  • I tried adding default route to my interface and now pinging ip is go throgh network but with 100% packet lose

enter image description here

  • once rebooting to windows; network is fine !_!

I'm confused..

Every thing happened today, no updates or changes done before closing the system yesterday

Any body could help me tweak over this problem ? No answer on the web or within my mind helped..

I can't surf the internet with the ubuntu (only) on my machine

the sitiuation now is that the pc could discover IP of router but can't resolve, ping or query domains.. it's connected using cat 6 eth cable 3 meters to the router, the same pc has another hard disk to boot with windows, and windows has no problem at all about connection.. actually my brother should be useing windows now to attend a video class.. the problem is with handling connection from only ubuntu lan and wan, even from the installed system or live iso,

Edits:

1: I followed some instructions and now I'm able to see router interface and ping it after restart, but not surfing the internet

2: I could now recall what cased that.. I noticed that the terminal is now no longer give output in my local language but in english.. I tried instailling ubuntu (no live session) on a USB stick before restarting the time I found this problem.. seems it reverted to my system environment rather than just stopping at the USB stick

anyway this seems to break my networks somehow, while all network configuration files are the same, but config itself has changed, same as locales on my system

3: add lspci and journalctl output

The problem was the legacy mini.iso which disrupted the internet connection when used over kvm

The only thing I could do is to reinstall from a fresh iso got from another device
