Ok this is some what easy... The Samsung unit is set to DHCP
by default which means it will obtain an IP address
automatically. The range of IP address that are handed out by the 3800HGV-B is default to 192.168.1.33 to 192.168.1.250. So it is safe to say that if you drop to a command prompt by going to start->run and type CMD <enter> then in the window type ipconfig <enter> your IP address should be in that range.
The unit will need to be set up below that range so I would recommend statically setting the IP address to 192.168.1.5... I know that sounds easy... In the manual for the Samsung on page 24 they explain how to naviagate the on screen menu. It does not look friendly, however the enter key and the menu key should get you to the network settings screen displayed on page 30.
You will need to set the network access setting to static, leave the http port at 80 and then enter in the IP address of 192.168.1.5 and a network mask of 255.255.255.0 the default gateway will be 192.168.1.254. As for the DNS settings you can leave those as is or blank they will not matter for web access.
Now you can access the web interface on the Samsung by following page 38... open a web browser (you must run internet explorer) and type http://192.168.1.5 <enter> it will as for a username and password XXXXX is username of 'root' and a password XXXXX 'root' (without quotes). It will ask to install an activex control (it uses this to display picture in the web page)... answer yes to it or watch the top bar for the active x install prompt.
From there it is all yours... Looks pretty simple to operate and work. Page 70 explains how to change the default password XXXXX I strong urge you to do so...
Have a good night and be patiencent with it :)
