Okay Heres whats happen.

JUST CLARIFYING i live in Auckland CBD so coverage is excellnt in my area, i live in the 11th floor of an apartment and balcony and windows are in my room.

Im using those PC Card Wireless Modems on my laptop for Woosh

Connect up, Internet runs perfectly fine, good stable speed etc for the next 10 Minutes, and then connection just drops, it says the nets connected on the Modem Dialer but the net just idles, after disconnecting Woosh and trying to reconnect it gives me this error message on the Dialer "No reply from Modem to Poll Commands" only way to fix this is to restart the computer,

Iv tried reinstalling the PC Card drivers and the Modem Dialer Program numerous times but the net always idles after 10 minutes,
I dont think its the Computer because i have no trouble connecting up to my neighbours Wireless Router that he uses Orcon on.

Can anyone help?
