My Main deco W3600 still frequently disconnect from the Internet when I access some sites or especially I play League of Legends. I try to test with the LAN cable connect directly from my ISP modem to my PC, this problem is gone. It's only happens when I use the wifi by Deco W3600. I think this maybe a bug of the firmware. I bought package of 2 - W3600. After finish setting up, when they turn to normal operation, nomally the LED light will turn green but one of them still have solid blue LED. I don't know why? Can you have me with this problem. Thanks.
