Thank you Carl, so I am guessing cant be gotten rid of but it doesn't affect bandwidth?. If I change channels will it follow or will it stay. 

@Carl sir how it is useful for one mesh ? Because i see it when i search available network from my laptop but in my android it is not showing this hidden network ssid. As well as it also have a password which is not known to me , so i want to how it works for one mesh because then is it required to put a password, plz give details about how it work and what its password is?

Another question is why this hidden network ssid only show in my laptop but not show in my android available wifi network. Because my question if it show then i think it should be show in every device but why it is not showing in android device

@Arindamxaverian 

Sir i also contact tp link india technical support and asking them about this hidden network ssid. They also do not understand it and they said that this is coming from your neighbours house which is near to you and who set up his router ssid as 'hidden network'

They unable to provide any information , is it not tp link responsibility to provide sufficint details about this hidden network ssid and its password and why this show in only laptop not in android. I think its a bug and i have to return the product

Routers have an option to hide the SSID, however it is not truly hidden since it is in the transmitted message and it can be seen easily by hackers. It was designed as a way to protect your WIFI but did not work. Many devices now show the hidden SSIDs, but not all. Since it does not do any good to mark your router's SSID as hidden, it is best to always show it. Also some devices use only 2.4 GHz or 5 GHz and they would not see any SSID on a different band. As far as the hidden SSID on TP Link routers, it is used as a back haul when using WIFI instead of a wired connection between a router and another router or an extender. For a Mesh system or extender to have the fastest throughput it needs a way to send signals concurrently. A Non-Mesh router and old style extender transmits the signal in packets from the router to the extender on the same channel or uses both the 2.5 and 5 GHz bands. If the same channel is used, the signal is not concurrent which results in a loss of speed (roughly one half the speed). If both bands are used, you are limited to the slowest band speed. A Mesh system or Mesh router and extender so equipped, uses the hidden band to send the the signal one way (back haul) and the other bands for the other direction so speed is maintained. Since it is used only to communicate between the router and another router or extender, there is no need for you to have the password which I suspect/expect changes frequenty. If there is no additional router or extender then the hidden band is idle. I would prefer an option that it could be disabled if not used.
