Hi can someone start me off with a little help please
I want to share an internet connection between 3 buildings they all have their own power .

Building A has a 2860n+ on the ground floor & a AP910C on the third floor these have a wired connection

Building B will have an AP900 ( 1 ) installed, initially it will be wireless until next year then I'll connect it with some outdoor cat cable underground in trunking

Building C will have another AP900 ( 2 ) wireless connection from both Building A & B

Buildings A & B will need to share 1 private SSID + 1 guest SSID 2#( 2 in total ) router ,APs A1 & B2
Building C will need to share the above plus have its own 1 private SSID + 1 guest SSID ( 4 in total )

I want computers to be networked together from all Buildings

I'm unfamiliar with AP's modes etc should they all be configured as aps repeaters or what ?
Initially just an internet connection between the 3 buildings and in the grounds between them is what I'm after .

Can you keep it as simple as possible please I'll work it out but I want to go in the right direction without too much hair falling out in the process :lol:

something like this
