belkin security

[Magnu420]

got another belkin wireless router cos mine died on me.. installed it correctly
secured the network but when i come to connect with lappys it wont conect
even though ive typed in the passkey for the secured network keeps comming
up summat like 5 or 13 digits passkey the passkey is a 8 digit,ive tried on all three
security settings wep,wep+wpa,wpa+psk no matter what i try in the properties
of the connection settings or the belkin settings the lappys wont connect unless
i disable the security....any ideas where im going wrong also ive done a few
belkin routers for networking in the past
