Hello, I am having a problem of really bad signal and Clients getting dropped off the AP
What could be the problem or how can i improve this? I am working with a Metal 2Shpn as AP
Attached a pic of my home showing some configs and signal.

somethings in my mind/
1- the antenna is in incorrect position
2- you use noised channel = bad tx/rx ccq
3- use unsuitable data rate according to the tx power of the routerboard
4- try to use b/g/n wireless mode
5- try to use 20/40 bandwidth
