    Intel 7260Ac with Asus N750JK slow wifi




      I have an Asus N750JK notebook and replaced the default wifi adapter (Qualcomm Atheros) with the Intel 7260AC+BT.

      This is done because i like to have the AC speed for wifi.

      My Router is the Asus RT-Ac68U (firmware: latest)

      I have installed the latest drivers for the card 17.1.0


      Now in practice:

      Because I noticed the slow wireless speed i did some testing:

      Both notebooks placed on the same spot, tests in succession.

      Speed test done with file transfert to Nas. Wired speed to nas is approx 100 mb/sec.

      We can clearly see the slow AC performance here.

      On 2.4g transfer speed is approx 14mb/sec on 5g max performance on 80Mhz is around 8Mb/sec.

      This is almost half the speed of the 2.4g speed.

      I've also changed some adapter settings, but no real difference.

      Do i have a faulty adapter or is it something else?
