I have recently acquired a new Thomson TG585 modem from telecom.
I have set up a name and password for our wireless network. When I try to connect from my computer to the wireless network i get the response 'invalid password' the password is correct. The only way I have managed to get my computer to connect is by restarting the modem.
Any idea what the issue could be?

wireless network name: packers
password: is a 9 digit 021 mobile number
computer is running OSX 10.6.4
