Hi
I have just switched today from Ziggo to KPN, all my devices are connecting to the internet including my windows PC, but my Linux Ubuntu will not connect. Works perfectly on my old Ziggo connection, and the network cable is lighting up, but no internet.
Can some please help advise?
Many thanks

Hello
Does the Ubuntu PC get an IP address through DHCP or is it static and set to an IP address in the Ziggo local IP range (192.168.178.x) which differs from the KPN local IP range (192.168.2.x)?
It's best to set it to DHCP and use a DHCP Binding in the modem if it needs to stay the same.
Hi
What if you ping anything ?
Or traceroute
( send from ubuntu )
Experiencing a similar issue. Moved houses/provider but kept same wifi ssid/pass. Everything connects fine except for my ThinkPad running Opensuse Tumbleweed. It seems to authenticate fine, but then doesn't get an ip. I removed the connection completely and nothing seems to work/help.

Did you configure the network connection to get an IP address via DHCP?
Does the ThinkPad get an IP address when you connect it with a network cable to the modem?
What KPN modem do you have?
Yes, dhcp, will check with ethernet, It's the box 14.
Also tested on ethernet, same behavior unfortunately. I already turned off wifi and tried my own AP's so it's looking like something incompatible in the dhcp server?
Captured some log output, seems indeed dhcp issues. I suspected ipv6 may be causing this, so I disabled that (both in box 14 and on laptop) but that didn´t improve things.

Try to give your ubuntu a fixed ip and then retry
Disabled DHCP, running my own now and also passing around a public dns server now, finally that got my laptop online (and every other device) without issues.
Time to get a R86s Mini PC instead of the box 14 that now only acts as a gateway.
Good that it’s working now.
Still very strange.
I’ve got several Lxc cointainer runnning with ubuntu 22.04.3 and dhcp is working there.
also a thin client with ubuntu 22.04.3 using wlan and dhcp no problem.
