Samsung LED TV Network Connection

leorick Wednesday, July 20, 2011 , , 4 comments :


Last week, I bought Samsung UA40D5000PR LED Backlit TV. It comes with wireless LAN adapter support but need to have Samsung LinkStick Wireless USB 2.0 Adapter in order for it to works. It also has an Ethernet port for wired network connection.



To utilize the network feature, I probably need to buy the LinkStick or lay a network cable from the TV along the way to my computer room.



So I'll go with the 3rd option, using old ADSL modem (Aztech DSL605EW) with built-in wireless and 4 Ethernet ports. This is the same modem that I used in previous blog post, broken ADSL circuit.

Reset the modem to factory default setting and set your wireless security accordingly.



Hook up the TV with the ADSL modem through an Ethernet cable. Set the TV network configuration; let the modem DHCP assign the IP.



At PC, download Samsung AllShare software, install it and follow the instruction to add video files to it's library.



Next is to connect from PC (from another floor) to the ADSL modem



It works. This would be my temporary method to link my TV to my PC.

My next step is to link the TV to not only my PC, but to my home network which linked to my Network Attached Storage that supports DLNA for media sharing. That would be fun.


I’m not planning to use WiFi since we have a lot of Wifi Hunter here. I’ll rather go with homeplug but not sure which model/speed to choose. I can see 85Mbps, 200Mbps, 500Mbps and 1000Mbps on the market. Any suggestion?

Using old Wireless ADSL Modem as a DIY Access Point

My current home network configuration is using ISP supplied ADSL modem that comes without wireless. It connect to a cheap unmanaged switch through a crossover cable and distribute it to 2 PCs.



I also have a broken ADSL modem (Riger DB108-WL) that comes with wireless capability. The only thing is, the ADSL circuit is broken. So this is where this idea comes out. How to use the spare wireless circuit with my current network configuration. I thought it will be complicated but when I give a try, it was not that hard. Just a couple of simple steps will do.

The main idea are to;
  • give the wireless device a fix IP
  • turn it DHCP server off
  • hook it up to the existing switch using crossover cable
  • set the gateway IP pointing to the current ADSL modem.
I assume you already know how to browse the wireless device web management page. Riger DB108-WL default user:pass is tmadmin:tmadmin

Part 1, to make it easy, just reset the wireless device to factory default through the pinhole. Then hook it directly to your PC using standard network cable. Set its IP for example, my current ADSL modem is set to 192.168.100.1. So the wireless device IP should be set to the same network segment, let say 192.168.100.50. Next, turn of its DHCP server since we want to let the current ADSL modem to control the host distribution. Now save and reboot the wireless device.


Part 2, Now the IP of the wireless device has changed. Disconnect it from your PC and hook it to the switch with crossover cable. Hook your PC back to the switch. Now turn on your wireless device and browse to its web management page. Set the gateway so that it point to the current ADSL modem (in my case, 192.168.100.1).


Now the wireless device is converted to wireless access point and ready to accept wireless connection.


The best part of using this configuration is, you can turn off wireless independently without need to browse the web management page. Just turn the wireless device power off.

For DSL605EW, please refer to screenshots below.

Web Based HTTP management GUI

leorick Saturday, July 05, 2008 , No comments :
When receiving a call from friend ask your help on "Hey! how do I open my ADSL modem Web Based HTTP management GUI?" and your answer "Oh! Go to command prompt and then type ipconfig or route PRINT and hit enter. Copy the gateway IP address in xxx.xxx.xxx.xxx format, Paste it at your Internet browser URL bar and hit enter" Suddenly he/she might ask you back, "What is command prompt?" or "How does IP address looks like?" or "I enter ipconfig at the command prompt but I get this response ip is not recognized as an internal or external command what went wrong?" (Maybe he/she type "ip config" with space instead of "ipconfig").

Then you should consider pass him/her below script. Script below automates process above so with a double click he/she could open the Web Based HTTP management GUI with default Internet browser.

Option Explicit

Dim oShell
Dim oShellExec
Dim oStdOutputText, sText, strTarget, strPingResults

Set oShell = CreateObject("Wscript.Shell")

Set oShellExec = oShell.Exec("%comspec% /c route print")
set oStdOutputText = oShellExec.StdOut

Do While Not oStdOutputText.AtEndOfStream
sText = oStdOutputText.ReadLine
If InStr(sText, "Default Gateway") <> 0 Then
strTarget = split(sText,":")
exit do
End If
Loop

Set oShellExec = oShell.Exec("%comspec% /c ping -n 1 " & strTarget(1))
strPingResults = LCase(oShellExec.StdOut.ReadAll)

If InStr(strPingResults, "reply from") Then
Set oShellExec = oShell.Exec("%comspec% /c start http://" & trim(strTarget(1)))
Else
WScript.Echo "******** Local router is DOWN ********"
End If

Set oShellExec = Nothing


Copy and paste above codes into notepad and name it as open_modem_gui.vbs. Note that the extension must be *.vbs.

IF he/she asked you "Hey it prompts for password now. How?" just ask him/her to refer to the ADSL modem user manual.
