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.
