The fix is upstream as of 3.12 and has been incorporated into the relevant upstream stable releases as well. So as long as you're on a relatively recent version of any currently supported kernel series this problem should not be present (kernels prior to 3.10 were not affected by the bug). > 2.) Does it fix the related bug for the iwl-1000 wifi interface (part oft my Lenovo edge e320), which has similiar symptoms on multiple access points with the same ssid (eduroam network)? I can't say for sure, but based on this short description I don't think it sounds related. This issue isn't related to multiple APs with the same SSID but rather to a small number of AP models from Netgear which transmit some invalid data in probe response frames. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1201470 Title: Invalid ECSA IEs in probe response frames causes connection to drop Status in “linux” package in Ubuntu: Fix Released Status in “network-manager” package in Ubuntu: Invalid Status in “network-manager” source package in Saucy: Invalid Bug description: The connection slowly degrades until dropping.
