Is this issue related to the issue I am having with the Intel 7260 WiFi
on Ubuntu 14.04 Server?

I have found that on 11n mode the connection is very slow.

The latency to WiFi router varies wildly between 1 to 100ms. Also using
SSH over the connection is very laggy and slow.

If I disable 11n mode (fall back to g) the latency becomes a stable
0.6ms and SSH is fluid.

My computer:
Mobo: Asus H81M-E with BIOS 2001
CPU: Intel Celeron G1840T
RAM: 2x2GB DDR3 Patriot
HDD: WD Red 1TB
WiFi: Intel Wireless 7620 mPCIe on PCIe adapter plugged into x2 lane (on MCH)
WiFi router: NetComm Liberty Series 3G18WV - 3G Wireless N300 VoIP Router

Also location is Australia and the WiFi is on channel 11 in case that
matters.

I am using latest linux-firmware (1.127.5) with firmware version
22.24.8.0

Also the connection sometimes stops responding completely.
