I have been asked by a friend to help him set up a network for his new coffee shop. It will consist of 5 bedrooms upstairs and a coffee shop downstairs. the 5 bedrooms will be used for student accommodation which all have a network point in for them to access the ADSL broadband. I want to keep all of the networks separate for security reasons, while downstairs in the coffee shop there will be free WiFi available, again on a separate network. So am i right in thinking i need to use a managed switch for this type of set-up. Also is there any type of switch that i should avoid and what sort of spec should i be aiming at. Many Thanks.
