I'm getting a solid wifi connection on win 8.1 but not so much on ubuntu. The connection on ubuntu works for the first few minutes before dropping dead. I get the connection back only after rebooting or by placing the system close to the router. - - ########## wireless info START ########## - - - Report from: 05 Dec 2014 09:00 IST +0530 - - - Booted last: 05 Dec 2014 08:58 IST +0530 - - - Script from: 20 Sep 2014 23:04 UTC +0000 - - - ##### release ########################### - - - Distributor ID: Ubuntu - Description: Ubuntu 14.10 - Release: 14.10 - Codename: utopic - - - ##### kernel ############################ - - - Linux 3.16.0-25-generic #33-Ubuntu SMP Tue Nov 4 12:06:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux - - - Parameters: ro, quiet, splash, vt.handoff=7 - - - ##### desktop ########################### - - - Ubuntu - - - ##### lspci ############################# - - - 01:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 6b) - Subsystem: Intel Corporation Wireless-N 7260 [8086:c262] - Kernel driver in use: iwlwifi - - - ##### lsusb ############################# - - - Bus 001 Device 002: ID 8087:8000 Intel Corp. - Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub - Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 002 Device 006: ID 048d:8350 Integrated Technology Express, Inc. - Bus 002 Device 005: ID 8087:07dc Intel Corp. - Bus 002 Device 004: ID 5986:054a Acer, Inc - Bus 002 Device 003: ID 04f3:0304 Elan Microelectronics Corp. - Bus 002 Device 002: ID 0bda:0129 Realtek Semiconductor Corp.
