Huawei wa1003a wireless setup

Is the laptop within normal range of the modem (wireless router ?). See the Huawei manual (may be on CD which came with it or on company's support website) for how to check that wireless SSID is being broadcast.
 
I'd contact Huawei by e-mail and ask for directions on activating wireless and broadcasting SSID (or see if they do actually have a manual you can have).
 
Then you may have to conclude that the Huawei is defective and return it to the dealer or importer for service under warranty.
