The netgear dsl wireless router and the 802.11b wireless USB adapter communicate with each other at home, and that works correctly.
A 'Cisco card' tells next to nothing. Cisco makes all kinds of communication equipment. And a 'wifi gateway notebook' might seem that it's wifi ready, somehow.
Wifi is the same as 802.11b. See, for example: http://www.pdabuyersguide.com/tips/wifi.htm. So I'm afraid it is some settings problem. Consult the documentation, or ask where you bought the laptop for help and possibly a demo. I assume that they are the ones who 'told' you should be able to use it, so let them show how it works.
I have a wifi gateway notebook.
I have a netgear dsl wireless router.
I have a 802.11b wireless usb adapter.
I also have a Cisco card installed.
I can get on the internet if I am at home, but I cannot get on the internet when I leave my home or am on the road or out of state. I was told I should be able to but I cannot. I will see that there is a wireless network available many times, but I cannot connect to it. What could be the problem.
