From 20 floors up.. great pool is straight down below my balcony about 190 feet.  Have good router.. Anyone do this?  Would appreciate a simple fix... Would like to keep slider closed, but could mount something on the balcony... Plug-in, range extender perhaps.. Main router is Dlink.. one year old and has both 2.4Ghz and 5Ghz.., 

You can try to put your router or range extender with strong antenna at your balcony without any interference. Wifi works best when there are no inteference and I guess you can get 2.4Ghz at best 20 floors up.

 

I'm not sure if you have rain/sun protection, why dont you use the public wifi provided by the building, assuming there is...
