After upgrading to Ubuntu 14.04 Trusty Tahr, my laptops’s wifi connection was unreliable, unstable and horribly slow in different wireless networks. Examing the situation in /var/log/syslog, I encountered numerous logged events of the kind

Obviously, the iwlwifi driver for my Intel Corporation Wireless 7260 card had problems in keeping a connection for more than a few seconds. Searching the internet, I found this thread, tracing the problem back to certain drivers having problems with Wireless N networks/access points and WLAN connections over the 802.11n protocol. On that thread, the proposed solution is to disable the N protocol and go with probably slower but more reliable variants of the 802.11 protocol. And indeed, disabling 802.11N made my laptop’s wifi connections operating in a stable way again.
