I previously had the following in /etc/modprobe.d/iwlagn.conf
options iwlagn 11n_disable=1
This made everything work for my Lenovo x200s. Then I upgraded and iwlagn was renamed to iwlwifi. Iwlagn was aliased to iwlwifi.conf however the options in the modprobe.d did not carry over. I had to rename the file to iwlwifi.conf (/etc/modprobe.d/iwlwifi.conf) and then change the contents to
options iwlwifi 11n_disable=1
This stops my iw card from going 802.11n but permits me to hold a steady connection.
I believe this is a continuation *but* not a duplicate of https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/876147
