You can combine OpenDns functionality with the hotspot to get a log of websites that users visit. It can block certain sites, and generate a report of domains visited, but will not list for example compressed zip archive files. The logs we keep are kept for at least 5 years.

It is possible to extend the hotspot coverage through the lan ports. You will just have to configure the router depending on the firmware. Please see this article in our knowledge-base http://www.hotspotsystem.com/deskpro/kb_article.php?ref=3253-USGC-4685
