Hello everybody!
I use my Asus Zenbook UX303L with Intel Dual Band Wireless-AC 7260.
The speeds I get via speedtest.net: UP 10 to 15 Mbps & DOWN 50 to 70 Mbps (I have 100Mbps UP&DOWN which I verified on LAN).
When I connect to my local NAS, I get 4 to 6 MBytes for download, which is so frustrating.
The router i use TP-Link 300Mbps Wireless N Gigabit Router (TL-WR1042ND), which is 3 m away and in sight.
OS is Win 8.1 Pro 64bit with i7-4510U and 8GB RAM
System power saving mode of wireless adapter is set to Maximum performance.
The 7260 Wireless adapter:
driver ver. 17.13.11.5
2.4Gh - auto
5.2Gh - auto
Ad Hoc ch - 1
Ad hoc QoS Mode - WMM Enabled
ARP - Enb

U-APSD - dis

When reading these forums, I read tip to change WMM from disabled to enabled, which actually helped a bit since NAS download speed ranged between 1 to 2 MBytes before.
I also tried to wirelessly download something from local NAS using other quite similar Asus with the same network adapter (and the same settings and driver) and its speed was approx. 16 MBytes. (Which is still not good at all, but still way better than mine.)
When using almost 3 years old Dell Latitude laptop, I get 70 to 80 Mbit on speedtest.net via wifi.
Thank you for your help.
