Ubuntu – Xubuntu Internet Connection Drops

intel-wirelessnetworkingthinkpadwirelessxubuntu

My problem is a little weird. My internet drops when I download too much data. For example when I download large files. If I just brows it will take a couple of hours to drop. When connection drops the icon still shows that I am connected but no website responds and everything times out. I can do ifconfig wlan0 down and then ifconfig wlan0 up and then on my taskbar click wireless icon and reconnect to fix this. (just reconnecting without ifconfig won't help) but then it will drop sooner than before. If I reboot it will again take a while to disconnect. lcpci for wireless card is as follows:

04:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 73)
Subsystem: Intel Corporation Wireless-N 7260 [8086:4262]

I read many posts about this issue but nothing helped so far. I had the same problem on my previous laptop with ubuntu and that one was way worse and I never managed to fix it. Any help will be very much appreciated.

EDIT : I have installed the driver again but not luck. I forgot how to check which driver it is running. lspci -k does not output the driver specs!

I have seen this in Xubuntu before, its down to the power management. Open a terminal and run the following:

sudo iwconfig wlan0 power off

and see if the issue occurs again while downloading

Ubuntu – Install Intel AC 8260 wireless drivers offline

The problem is that kernel 3.19 does not support firmware version 13 that you can get for Ubuntu 14.04.

The easiest way to do offline is to install Ubuntu 15.10.

The adapter should work without any effort.

You can get it working on Ubuntu 14.04, but you will need to upgrade the kernel and the firmware. I can give you directions.

But you will have to download some packages using another computer and then install them to Ubuntu.

Install to Ubuntu 14.04

Reboot and test the Wi-Fi.

Ubuntu – WiFi not working after latest Ubuntu software update

I booted in to the Bios Menu page, but hitting F-12 when the Dell logo appeared during boot up... I found the SecureBootMode setting under the Security settings, and disabled it, then after rebooting everything was fine.
