Wifi Router at resort

I have an airport express and my mac. I know I can connect my airport express and let it connect as a bridge to the resorts router and then up to ten devices can connect to my airport.

In order for the AirPort Express to provide a wireless network, it must be connected to an Internet source using an Ethernet cable, so it cannot perform the duties that you describe in your post if the resort is providing only a wireless signal.

Can you clarify on this?

I dont know how to set up the mac for internet sharing with other devices so thats also what I need to know.

If the Mac is setup for Internet Sharing and is receiving a wireless signal, it cannot repeat or share the wireless signal. It can only share a signal at the Mac's Ethernet port.

If it turns out that the resort is wireless only, it might be possible to configure one AirPort Express to "join" the wireless network and provide an Ethernet signal to a second AirPort Express which would be configured to 'create a wireless network" for up to 10 wireless clients. In my traveling experience, this type of setup will work approximately 50% of the time.

Please see updated answer.

Usually hotels and resorts offer wifi service without access restrictions pertaining to the number of devices that can access a wifi connection. Perhaps you misunderstood their explanation of wifi service. In hotels I've been able to use AirportExpress as a wifi router using DHCP or as a wireless access point (i.e. no DHCP) while hooked up to the hotel Ethernet connection.

That is not my experience at all. I usually have to review the bill and point out at check out that I am a hotel club member, etc to get the charge reduced to access for one device per day.

Hotels have become a lot more sophisticated in the last few years and most them now make you log in separately for each wireless connection if you are connecting directly to their wireless.

If I am lucky enough to get a hotel with an Ethernet connection, I can usually configure the AirPort Express to hand out IP addresses to each connected client. That way, the hotel router only "sees" one device....the AirPort Express.

Would't AirPort Express work as network extender? Just to extend the resort's wifi connecting to it with given id and password and all the clients, in this case nunes013 and the company, connecting to that AirPort Express? I guess in that case all the connections would be recognized by resort's wifi router as the only one.

The problem might be if the main wifi router is set to not allow network to be extended....

Extremely unlikely as this is a proprietary feature among Apple routers and is not compatible (as far as we know) with devices from any other manufacturer.

It would work.....IF

1) The main router at the hotel and all wireless access points were Apple "n" wireless devices

2) The main Apple router has been configured to allow its network to be extended

Even if this could be configured, the Airport in the room will be in Bridge Mode, so the hotel router will pick up the MAC address or AirPort ID of each device and charge for each device that connects.

..the email form the hotel implies you can get a code for each internet device..

.. i meant to say that wifi is open to many users at a hotel but is usually restricted by room number or an assigned wifi account number.. however, i think the poster will be able to buy multiple wifi accounts from the hotel.. or share one account number between users.. one user at a time.
