I have had my DIR-855 since it was first released and I have had many issues with wireless signal dropping to disconnections. I had bought the DWA-160 Rev.A thinking that it was going to fix my issues and it did not. I exchanged to DWA-160 Rev.B and installed the Ralink Drivers but I still had the same issues. I did some research and stumble up the Preamble settings. The router calls it Short GI. Checking or unchecking the Short GI setting in router did not fix my issues however setting the preamble setting on the Wireless adapter from Long/Auto to short fix my disconnect issues. The way I did this with the DWA-160 is by setting the driver setting to Game mode by going into the driver properties under the device manager and clicking on the driver tab. Mostly all Wireless adapter have Either a Preamble or game mode setting under the driver tab. I set all my dell wireless adapter to short and everything is working great. Cisco recommends that wireless devices be set up with short Preamble, and in case your wandering what is the difference - Long preamble nothing more than a fix for issues related to the older b wireless standard and Short actually lower down the wireless latency which is why is used for game mode.
