Intel Wireless-N 7260 dropping connection

I have a Lenovo Yoga 2 Pro running 14.04 which according to dmesg has a Intel Wireless-N 7260. The wifi is not working correctly. Every 15 minutes or so it will ether get really slow or drop connection altogether. I have found many other questions about this same issue but the solution has always been to upgrade the firmware and I have the latest.

> dmesg|grep wifi

I have the same problem with a carbon X1 gen2. The only solution that worked, was to download and install a new kernel. Download the following packages from

linux-headers-3.17.0-031700rc2-lowlatency_3.17.0-031700rc2.201408251935_amd64.deb
linux-headers-3.17.0-031700rc2_3.17.0-031700rc2.201408251935_all.deb
linux-image-3.17.0-031700rc2-lowlatency_3.17.0-031700rc2.201408251935_amd64.deb

Type the command below on the terminal:

sudo dpkg -i Downloads/linux-*

After that reboot with the new kernel.
