After upgrading from kubuntu 13.04 to 13.10 suddenly my wifi connection is very slow. Ping times are varying from 200 up to 1500 ms to www.google.nl.

When I connect my ethernet cable they drop to normal times like 8 or 9 ms. Anyone experiencing the same problem or know a solution I can try? During the upgrade process a few times they asked whether I wanted to keep or replace some kind of configuration file. I'm not sure anymore which file it was, but maybe this has something to do with it. Before the upgrade both wired and wireless connection worked perfect.
