Dear All,
I've got a problem with my brand new Lenovo Thinkpad T440s and Intel Dual Band Wireless N 7260.
I run the speedtest.net on it.
Connection between my router (TP-LINK- "n" connection established) and my t440s is in amount of 144 mbits.
I've checked my t440s with speedtest.net and the highest download value was 20 Mb/s. It seems to me like it is only b/g connection.
What should I do to receive hi speed (80mbits) connection?
All my older notebooks my WiFi works with speed of 80 Mb/s. So there is a problem with t440s 
I have updated the drivers to 17.0.0 and it is a bit better - download value is amounting of 34 Mb/s, but still it's not 80 Mb/s
I've checked in Intel Dual Band Wireless N-7260 driver settings - Energy management - Permission to disabled this device due to energy save is not on.
In Power Supply Profiles I set the Maximum performance in WiFi card settings.
My router is TP LINK WR841-N (run in N mode)
Dear Intel it's funny that brand new Wireless card works slower than iPad mini Retina or my 2 old Dell computers.
Any suggestions?
