Asus Laptop 102g problem...pls help

Hi all
I have an Asus A6R-B012
The wireless card (i think) is an 102g
My problem goes like this....
Im from Romania..i recently got a scholarship in France....all good...till i tryed to connect to the internet...using wireless...
I dont know the name of the AP...but his SSID..is NETGEAR...
this AP is the internet connection of where i live now....it has maximum signal..but when i try to connect..it says..."limited or no connectivity"...when other peoples here connect to it it works just fine... I installed windows again...i updated the drivers...but no luck...same-o same-o
Near there there is an hotel...i got the wireless connection from there and it works fine...but it has poor signal and i get disconected..

Do anyone of u know how to solve my problem....im not very good at this wireless thing.
I think there;s something wrong betwen NETGEAR and ASUS...maybe u know the answer

Thanks
