Internet is dying

Hello
My internet connection has become fickle. It happens that there suddenly is no
more internet connection at all. When I "ping" some site, then there is no
output at all. KDE say that the IP of my machine can't be acquired. Then I
can't contact my laptop, which is connected to the same router, either. Not
even my dynamic DNS address (same machine) can be accessed. Then I have
to reboot to get the connection back.
That used to be once or twice a day, but now it looks like it happens all the
time.
There are some suspicious messages in /var/log/syslog and /var/log/kern.log.
In syslog:
