I need to build an area-covering Wireless Lan in a hotel.
The house has three floors with about 20 rooms, altogether 800 square meters.
I have one DSL-Broadband-Router now, from there on you have to plan the AP or watherever.
I will put your advice into praxis here with a local building team.
So I need your advice what hardware I have to buy - where I have to place it, and remote support until it works - maybe (if you like) remote support if there is a need to update something
You will find a plan of the house attached.
