WEP Secured networks are not supported by the AstroBox software. WEP has numerous security holes and was deprecated in 2004 by the IEEE. Some routers still support it and some people might still be using it. However, routers should also have the option to use WAP or WAP2 which we support without problems. This is a better option for your users as it provides a higher level of protection for their networks (especially WAP2)
