Did reset on my asus ac68U with FW 378.56_2 and still not working

[Efraim]

I was having the issues with 2.4ghz wifi clients, but i coundn't even connect to my wifi.
So, i did the reset with WPS button, put my router on rescue mode and installed 378.56_2 FW. Then i did the reset again, by the same method, and configured my router. Now all clients connect to the 2.4ghz wifi, but i have a terrible speed! I dont know what else to do to recover it completely, since i already tried all FW i could find.
Right now i have NAT acceleration on AUTO, QoS disabled.

Ok, i read the topic from Merlin, and perhaps is my bandwidth. My router stay by the side of my ps4 and tv, and they use bluetooth for controllers. I will try changing from "only 40mhz" to "only 20mhz". The control channel is on "channel 6" with "above" on extended. Wireless mode on "n only" , since all devices are 802.11n. I really need to put it on "auto"?

All devices are connecting, but beside the terrible speed, if more clients connect, it starts dropping the connection to internet. At least it doesnt disconnect the wifi like before. On my system log, there's nothing, only when clients connect. Reset the GUI, you mean "restore" on "administration"? Re-do all configurations

40 MHz is nearly impossible to maintain in a typical environment, too many interference, starting with your Bluetooth controllers which also use the 2.4 GHz band.

Also upgrade your firmware - Asus recently added a setting to enable/disable Bluetooth coexistence.

It stopped working because of the lastest update from asus. I dont want to lose my 2.4ghz wifi connection again. If i change the NAT Acceleration after the lastest update, will it work normal as well?

NAT acceleration has no impact on wireless performance.
