Wi-Fi Questions/Suggestion - Beacon Interval

The latest change I made to my wireless router was setting the beacon interval from 100 to 20. This is the lowest setting the interface will allow me to set it to. I noticed two exciting changes after I changed the beacon interval, but I want to see if you guys know if I am going to damage my devices with this setting.

  1. The ping dropped from ~15-100 to a solid <1ms with very few in the 15ms range.

  2. In Acrylic Wi-Fi it squelched out the 20 neighboring signals.

I am an IT guy, but I don't have extensive knowledge of wireless technology. I have been tweaking my Asus RT-N56U since I bought it to try to optimize it for streaming video. There is no room for error when casting a tab at 720p high bitrate to the Chromecast. I bought this specific router to allow open NAT with two Xbox Ones. Routers that support UPnP that well are rare, and this was on sale. I have not added a standalone access point because I am a cheap ass. I feel like an $80 wireless router should work fine considering my previous wireless router was a $20 TP-Link which had great wireless but would not support open NAT for two Xbox Ones.

Question: Will a beacon interval set to 20 damage my devices or be bad in any way? Why did this change squelch out neighboring wireless networks according to Acrylic Wi-Fi?

Suggestion: Try reducing your beacon interval if your 720p high bitrate Chromecast is intermittently choppy. I pinned it down to the network issues when I would watch movies and see that the laptop was getting the video stream without a glitch and notice that the TV would pause intermittently corresponding with the increase in latency between my laptop and my router. If the ping went above ~100ms it would cause the video to become choppy until it corrected back down to ~1ms.
