I have also tried adjusting Remote RSSI but still no luck.

Have changed the distance option to indoor. After pinging i receive destination host unreachable..!

This is distance that i need.let me change the config and will share the update.

In distance setting of the device the default value is set to 4km in both devices. May it be the reason for poor signal strength

distance between them is only 20m.

Model : Hardware Version : Firmware Version : ISP : Hi , I was configured Bridge mode(point to point in TL-WA5210. But i made sure the line of sight is o.k . whe i try to run timed ping to the device...
