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.
