Slow wifi after with Centrino Wireless-N 1030 [Rainbow Peak]
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.

Solution 1:
Do:
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi
Go into network manager and change your wireless settings to match the screenshots.
Go into your router and change 802.11bgn to 802.11bg then save the settings and reboot router and computer.
Lets modify this file: sudo /etc/modprobe.d/iwlwifi.conf change
options iwlwifi 11n_disable=1
To:
options iwlwifi 11n_disable=1 iwlwifi bt_coex_active=0
