I’m running a Sony Vaio Laptop with Tumbleweed for about one year. For the network connection I use the KDE network manager in the toolbar. Suddenly, I cannot reach the internet anymore (e.g. by opening firefox or fetchmail).
The strange thing is, I am still in the internal network, i.e. I can exchange files via Samba with my Windows laptop. The Windows laptop can reach the internet fine, by the way.
I ran the following commands which I found in another thread here in the forum:
ip -s link ip a ip r grep -v -e ‘^#’ /etc/resolv.conf ping -c 4 192.168.1.1 ping -c 4 18.104.22.168
The output of the ip commands looks “normal” to me. The /etc/resolv.conf looks like this:
# Generated by NetworkManager search home nameserver 192.168.0.1 nameserver 2a02:810d:1980:5028:5e35:3bff:feff:473
The ping commands give no reply from 192.168.1.1 or 192.168.0.1 but full reply from 22.214.171.124
Above, I said “suddenly” I have no internet, but there is one thing I changed in the Network Manager: Usually, I use the cable connection to my router but once I tried to connect to my router via WLAN. This took many tries in order to convince the Network Manager to do this without using the password safe which I don’t have the password of. The description of the check boxes seems not right nor logical to me. Finally, I managed the WLAN connection but had no internet. Since then, I tried at different locations with different WLAN routers and also my home router via cable but I only ever get the connection to the internal network, never to the internet. To make things even more complicated I have a new home router now and cannot test on the old one anymore…
