Hi there
The Senao 2611CB3+DLX are set to Point to Multi-Point Bridge mode by factory default. This is the mode you will need to be in to connect to the Hotspot. As the manual says you will need to set a static IP address on your PC to access it.
Under wireless if you leave the SSID field blank the Senao will connect to the AP with the strongest signal, or you can enter it in. Under ADMIN you could try DHCP and the hotspot may allocate it an IP address, or you may have to find out what Subnet it is in and Gateway address and manually enter them into the Senao. You also might need to tick the clone MAC address box. You may have problems running multiple PC's on the connection because the Hot Spot may only want to talk to one MAC address, and you would need a router to allow your setup to work.
The good thing about the Senao is that there is not too many setting to play with so if you keep trying you will get it working. Make sure you only have one PC on it for a start and you will need to use a crossover ethernet cable.
Good Luck
Dale
