I have got two routers

Netgear Cable Modem router , I tried to use my laptops (Toshiba XP SP3) with two different wireless cards, built-in and USB stick (Netgear WG111 v2),,,both of them are working fine.

Then I tried to use the same laptop Toshiba (XP SP3) on another router (NetComm NB5 ADSL2+) which is on different ISP ,,,,Laptop’s built-in wireless is working fine, but netgear wireless USB stick did not work!!!!!

Although I am pretty sure that wireless settings are correct.

I tried another netgear wireless USB stick,,,,still same issue.

What could be causing this problem going on ?

I tried to use netgear wireless USB stick on a desktop still I can not get them work
