We're running the Netgear wfs709tp wireless switch, which supports a captive portal for authorizing users, as well as a separate guest/contractor network. Both SSIDs are encrypted with WPA and thus require login, but the guest login we just give out to guests en masse. We don't track guest access individually.
Management says we must display a disclaimer to guests saying that they use the network at their own risk, etc. The box has a place to create custom login pages, and we can create a disclaimer for the staff network, but the HTML code we enter for the guest network never seems to appear. We just get the ordinary plain vanilla login.Netgear is silent on the subject, saying they will support the actual wifi operational aspects, but not the "window dressing" features, which they say customers are on their own to support. They say they won't debug HTML code for customers. Attached is the HTML code we used. We've tried it both with and without <HTML>, <HEADER>, and <BODY> tags with no change.
This network is provided as a courtesy to our guests. You use it at your own risk and are responsible for ensuring your own security.
