This needs to be clarified a little bit. You mean applications are not getting started after wifi connection has been established? But already running applications continue to run? If yes, that's most likely computer's hostname is changed when you connect wifi, the communication socket to X has hostname in it's path, and if it was changed then new applications search for a different file and silently fail to start. To check this assumption you need to check with hostname the box has before connecting to wifi, connect to wifi, check hostname again after wifi is connected (probably you will need to switch to terminal ctrl-alt-f3). It is possible to reconfigure the network software to ignore hostname provided by access point. Just let us know here if the hypothesis is your case.
If that's not the case, then we need more logs. Prepare log collectors before connecting to wifi, I do not know whether you're running openrc or systemd, so here's all the commands for both of them | Code: | # dmesg -w | tee /tmp/wifi_problem_dmesg.log
# tail -f /var/log/messages | tee /tmp/wifi_problem_messages.log
# journalctl -f | tee /tmp/wifi_problem_journalctl.log |
connect to wifi and check changes in logs. Provide here (if they're too huge - use wgetpaste) so people can also see what happens during wifi connection. |
Hi, thanks, the solution was easy, I simply reattached my wifi device to usb.... and it works now good.
I don't know why but after I do something in my windows and then restart to gentoo, I need to reattach usb device which is responsible for wifi stuff in my desktop pc.
But this time, I haven't loaded windows for a long time.... so it's strange. |
