hi,

maybe someone can help me with my networking problems.

after upgrading to kde-4.7.3 i cant get my network connection running. i have 2 network controllers on my board, but none of them shows up at the systray-icon (using networkmanager and networkmanagement). (if i move the mouse over the icon a bubble says: 'no network interfaces'.

anyway, the configuration of the interface seems to work (at least partly). the interfaces use the correct kernel driver and get an ip4 address from my router and i can ping some internet hosts. i even can ssh into the box. but if i try to get some data from the internet (e.g. emerge a new package, browse some homepage. emerge --sync also fails with timeout) the connection always times out.

i've tried various things to get the network running, including a 'reemerge -va --with-bdeps=y --noconfmem world' but nothing helped so far. (possibly i'm missing some package?)

many thanks in advance,
cri

some information from my system. please let me know, if you need further information.

Which Plasma NM and NetworkManager do you use?

What does the script below return?

for i in $(qdbus --system org.freedesktop.NetworkManager | grep /org/freedesktop/NetworkManager/Devices/) \
do\
qdbus --system org.freedesktop.NetworkManager $i org.freedesktop.NetworkManager.Device.Driver\
done

What device serves as the gateway to your network? If your edge device or your ISP mishandles PMTU discovery, you can experience the problems described. Small transfers work, but large transfers, such as emerge --sync or big package downloads, will fail.

Since the TS does not answer: I have the same problem. I resorted to manual wpa_supplicant configuration to get wifi working again.

Since my troubles began with a major system update, I'm not really sure what broke: NM got updated and KDE as well.

The output of the commands lamarque posted are (run by hand):
Quote:
cyberwizzard@cyberxps ~ $ qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/Devices/0 org.freedesktop.NetworkManager.Device.Driver
sky2
cyberwizzard@cyberxps ~ $ qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/Devices/1 org.freedesktop.NetworkManager.Device.Driver
iwl4965


The file in /var/lib/NetworkManager/NetworkManager.state says everything is enabled.

The '.xsession-errors' log does not mention anything about the network, wpa or the widget.

I tried recompiling everything like the TS did and it did not work.

I also tried removing my kde profile - which did not help.

[Update]
Downgrade to NM 0.9.0 did not help.

I've moved my user settings to /etc/NetworkManager/nm-system-settings - it seems they are in a different format than NM 0.9 expects (0.8-formatted?) so using the source and NM with debug output on, I managed to transfer all my Wifi networks to the system level. Now NM can start them without GUI interaction.

I did spot that 'kde-misc/networkmanagement-9999' got installed for some reason. I downgraded it to 0.8.98 and I got a new '/etc/dbus-1/system.d/NetworkManager-kde4.conf' which uses different naming for some keys. I will reboot momentarily to see if that improved anything.

[edit]
Solved! Downgrading to 'kde-misc/networkmanagement-0.8.98' restored the KDE NetworkManager interaction.

I removed the file /etc/dbus-1/system.d/NetworkManager-kde4.conf in Plasma NM 0.8.99 and master branch (kde-misc/networkmanagement-9999) since it is not used anymore. The file was used with NetworkManager 0.8.x only. I do not see any reason why it works with 0.8.98 and not with -9999.
