WMM was on "disabled". "Auto" or "Enabled" doesn't limit the speed at 54 Mbit/s anymore.
The router is a "Livebox Play" (provided by my ISP). The chipsets inside are AR9382 and AR9380 by Qualcomm Atheros. This is not Wifi AC.
When i connect, i get mostly 144 Mbit/s at 2,4 GHz and rarely 300 Mbit/s at 5 GHz. When i configure manually the full SSID in Windows (with the end with MAC adress), it won't connect to it. I did the same by entering the full MAC address instead of SSID, but Windows won't connect.
This is WPA2 - AES
Lucius Snow, the Asus setting of "disabled" is out of spec for 802.11e/802.11n, you could report it to Asus so they can try to get this fixed in the next release. I wonder if this is an Asus or a Broadcom bug?
I think Asus doesn't change driver updates, but it likely duplicates the settings in their own release OS image, which means some Asus Engineer(s) might have tweaked this setting to "fix a something" and caused this problem, or it was set that way from the original Broadcom install.
One way to check might be to Restore Defaults in the Advanced settings for the Wifi driver Properties - if it is available - my Killer 1202 doesn't have a Restore Defaults option. Be sure and note all the settings before doing this, so you can put back the options changed to restore the original settings.
When I configure manually I don't put in the MAC address, I only put in the SSID... you could also set it up normally - selecting the SSID from the list, then check the Advanced option to connect even if the SSID isn't visible - if that is the goal. You can also set this by right clicking on the Adapter icon => Status => Wireless Properties => Set connect even if the network is not broadcasting it's name (SSID).
So this is a problem that all G750 Broadcom BCM4355 (BCM43xx) 802.11ac owners should check - make sure WMM in the Device Manager Wifi Adapter => Properties => Advanced settings is set to WMM Auto or Enabled, if set to Disabled.
Thanks Lucius Snow!
