The root of this problem is that there is no &quot;control channel&quot; (or whatever you want to call it) from an ISP to its customers. Email doesn&#x27;t work because ISPs don&#x27;t always have the customer&#x27;s address and email can get spam filtered. Paper mail is expensive and may not be read. Until someone defines and implements a protocol for this, ISPs are going to keep inventing weird kludges. I wonder if Hotspot 2.0 can be adapted for wired networks.
