386.5 Firmware installed on my Asus RT-AC1900p

[Railcoastie14]

Just installed the new 386.5 firmware on my RT-AC1900P Asus router. After completing the install i ran speedtest.net and only get 142-180 mbps down now....I pay for 400 from my ISP and with the the 386 3.2 firmware i run 430-470 mbps down....Hope you can find and correct the speed slowdown in the 5.0 ASAP.
