I'm experiencing the same problems (XPS13 developer edition with Centrino 6235 out of the shelf) , but now I noticed this from Intel: https://communities.intel.com/thread/31090
""" Edited 9/5/2014 by John S. (Intel Customer Support). The 17.1.0 version of Intel® PROSet/Wireless Software and Drivers has fixes for connectivity related issues with the Intel® Centrino® Advanced-N 6235 wireless adapter. """ So Intel claims they have finally fixed the issues (after 2 years) in their windows drivers. Now, can anyone make some detective work to see what are the corresponding fixes on the linux drivers and could we backport them? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1091372 Title: 8086:088e [Dell XPS L322X] wifi slows and/or drops frequently To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1091372/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
