Update: Latest Ubuntu 14.04 update has corrected connectivity issue. Full 70/70 connection on AC wifi on 2.4ghz, as well as 5ghz.
Testing on both 3.15RC3 kernel as well as 3.13.0.24 kernel - stability and connectivity improved. Seems to be a non-issue at this point. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1315202 Title: 8086:08b1 (rev 73) [Asus M5A97] Intel AC7260 Drops AC WiFi Status in “linux” package in Ubuntu: Confirmed Bug description: Desktop machine with Intel AC7260 + Bluetooth drops AC 5ghz wifi connection.
