A friend has one with his DSL service. I was planning to put in a wireless router (which I may still do depending on need) and discovered that the Westell 327W modem also has a built in router with cable/wireless capability. There is a forum that deals with DSL matters, and it addresses this particular system. I found this useful. http://www.dslreports.com/forum/remark,12262394 Note in method one - 192.168.5.2. should be 192.168.50.2 - the third numbers (octet) should be the same. One can use the modem/router strictly as a modem and let the separate router be the network (LAN and DHCP) controller. I'm used to a dump modem without the router built in.
