Query: Very Disappointing!

Despite the slick marketing effort (i.e. "With SRX"), this product falls short.The installation disk is useless.Customer support was good, when I could get through - which was not very often.I constantly lost the wireless connection.I constantly had to re-boot.Despite significant effort (utilizing the online help features) I could never obtain a secure, encrypted connection.No more Linksys for me!
