Install and set-up NetworkManager on both the server and the client.
On the Server
Plug the wireless adapter into the computer which you wish to use as the server. Click on the nm-applet in the dock and choose "Create New Wireless Network".
With the dialog box, type in your SSID and choose your security type and password, then click "Create".
Afterwards, right-click on the nm-applet in the dock and choose "Edit Connections". Click on the "Wireless" tab and select the SSID for the network you just created. Click on "Edit".
With the dialog box which pops up, make sure "Mode" is set to "Ad-hoc".
In "IP4 Settings", change "Method" to "Manual" and click on "Add" next to the "Addresses" box. It then should highlight the box to the left where you have to enter three IP addresses.
For "Address" choose a value between 192.168.0.0 to 192.168.255.255; "Netmask", 255.255.255.0; "Gateway", 1.1.1.1. then click save.
Finally, click on the nm-applet in the tray again and select "Connect to Hidden Wireless Network"; then in the "Connection" drop-down box select the network which you just created. It should then connect.
On the Client
On the nm-applet in the tray, click on the wireless network you created and connect to it; afterwards, right-click and choose "Edit Connections". Again, click on the "Wireless" tab and select the SSID for your network and choose "Edit".
In the "IP4 Settings" again change the "Method" to "Manual" and click on "Add" next to the "Addresses" box.
For the "Address" choose a value between 192.168.0.0 to 192.168.255.255 but make sure it is different to the one you selected for the server; afterwards fill in "Netmask", 255.255.255.0; "Gateway", 1.1.1.1. then click save.
It should then allow you to connect to the server (try pinging the server to ensure this).
