Need Help P3 to Internet via Wireless Bridge

you wrote

Okay, I ran ipconfig on the office laptop computer

only to avoid confusion and misunderstandings: this is the computer we are talking about here? Otherwise the IP settings are not interesting.

you have 2 different IP ranges: 192.168.1.x and 192.168.2.x, depending on the netwrok adapter you are using. Which adapter is used for connecting to ProfiLux? This adapter determines which IP ProfiLux must have.

To be honest, I still don`t understand your home network. Is there a router? How is what computer connected to it?

Maybe a detailled description or even a drawing would help, at the moment I am a little lost.

And you didn't answer my question

are you able to access your router and check the settings in it? what is the IP address of your router?

Hi Matthias, tell me about it. I am

too. Here is the dilemma. da Artsy Cube is located at work. We have two routers, a direct LAN line router and a separate wireless router system. The settings I posted are for both routers. the 192.168.1.1 is the LAN router. The 192.168.2.1 is the wireless router.

to make a long story short. . . I did it

I configured the LAN line first. Then, once that was done, establishing the bridge system was a bit tricky, but I got that too . . .

As you pointed out, there are two routers. Your tip about understanding the series of numbers was very helpful. When configuring the wireless router and bridge, I had to change the 192.168.1 family to 192.168.2 family. It was really not too bad on the bridge.

the major issue I had was understanding how to configure the P3 CONNECTION and the SYSTEM / LAN settings. Once I understood this, things came together.

I will try to put together a synopsis and some photos of my system and configuration. I'll post it on RC and place a link here too.

I do appreciate you stepping in and helping me with configuring the P3. I do think this was appropriate, as my problem was not in configuring the bridge. It would be nice to see a set of instructions for configuration. I did review and read (several times) the LAN/WLAN instruction. However, to tell you the truth, they are difficult to follow. The instructions veer off from LAN and really focus on the WLAN installation. It goes into the software configuration which is not helpful when trying to establish a LAN connection.

I would encourage a set of instructions specifically for the P3 and establishing a LAN connection. If people can this connected, then setting up a bridge is fairly straight forward.

For those following along, this is what I discovered in a nutshell: Understanding all the pieces involved was a great step for me to figure out how networks work. So, I laid out a map and parts and addresses. Hope this helps:

Devices:
1. Wireless Router = IP 192.168.2.1
2. Wireless Bridge = IP 192.168.2.2
3. P3 with LAN Port = IP 192.168.2.3
4. Computer (anywhere in the world) with Profilux Control

Devices 1-3 have specific addresses, called IP address. This is your device address, like a home address. Therefore, every device will have a unique Home Address. You need to know the address of the first three devices. You don't need to know the computer address (except for when you are programming all the devices).

The default mask will usually be the same for most people = 255.255.255.0

The Default Gateway is your mailing address. This is where you want to transmit a signal to!

First step, you must know the address of the Wireless Router. All other IP addresses will be set based on that device. In START menu, type "cmd" into search field. DOS box pops up and type "ipconfig"

Record the following information (I give mine as example):

Wireless LAN adapter Wireless Network Connection
IPv4 Address: 192.168.2.101 = home address = this computer
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1 = home mailing address = wireless router

In other words, I am mailing a message from my home address (192.168.2.101) to the mailing address (192.168.2.1). When the message gets to its final destination, the wireless router, it gets broadcast onto the Internet. This is where we want the messages to go. I hope this analogy is helpful for some folk like me that does not really understand all the networking stuff and jargon.

Now that I know the wireless router IP address, I can program the other devices. This is important because the other devices must be in the same family as the wireless router. In this example the family name of the wireless router is 192.168.2
All other devices must have this family address. In the fourth section of numbers, you can enter any value from 0 to 255, but all three devices must be different and you must know them.
As you can see, I am keeping things simple. The family is all the same number: 192.168.2
Wireless Router is .1, Wireless Bridge is .2, and P3 is .3

Step 2 is to program our wireless bridge. I used a Linksys WRT54G with firmware v24-SP2. Follow the online tutorial and this should be easy. http://www.wi-fiplanet.com/tutorials...le.php/3639271
Another option is to purchase a gaming router for about $60. It comes with instructions that will tell you how to program it. This is by far the easiest way to get a working bridge, but you pay more for it.

When programming the Wireless Bridge, this is what I used for my system:
Disable DHCP (follow tutorial)
IP Address: 192.168.2.2 = Home Address for the Wireless Bridge
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1 = Send Messages to the Wireless Router
REBOOT Wireless Bridge

Step 3 is to program Profilux 3. I did all the programming through a USB connection and Profilux Control 5.0.0.7
P3 Settings CONNECTION :
Name of connection: da Artsy Cube (use any name you want)
Host-Name: 192.168.2.3 = Home Address for the P3 itself. This means you can use any computer in the world to find your P3 by dialing its IP address.
Port: 10001
Search automatically: unchecked
Search for SMS module: unchecked
Device address: 1
Type of connection: TCP/IP
Timeout: 5000ms

P3 Settings SYSTEM / LAN:
Obtain IP address automatically: unchecked
Use following settings: checked
IP address: 192.168.2.3 = Home Address for P3
Subnet mask: 255.255.255.000
Default Gateway: 192.168.2.2 = Send Messages to Wireless Bridge

Viola, you will have access to view and control P3 computer from any computer in the world. This is the flow for viewing P3 settings on any Internet Browser:
Call P3 at http://192.168.2.3, now P3 answers the call and sends a message to the Default Gateway 192.168.2.2 which is the Wireless Bridge connected to the P3 LAN port. The Wireless Bridge then sends a wireless message to the Wireless Router at my office which is done by Default Gateway 192.168.2.1. And there it is. Once a message hits the Internet it can be viewed by you anywhere in the world. When viewing the settings, it is very basic. I hope some improvements come in the future. I think some other people have figured out a way to view more stuff, but that is beyond me right now.
The second and likely more important task, is to physically control your P3 anywhere in the world. For this, you must use computer with Profilux Control software installed (keep it on a thumb drive if travelling and using Internet cafes). Then all you have to do is program Profilux Control P3 as you did before:
P3 Settings CONNECTION :
Name of connection: da Artsy Cube
Host-Name: 192.168.2.3 = Home Address for the P3 itself. This means you can use any computer in the world to find your P3 by dialing its IP address.
Port: 10001
Search automatically: unchecked
Search for SMS module: unchecked
Device address: 1
Type of connection: TCP/IP
Timeout: 5000ms
Press connect and you get it.

OK, I’m tired. I’m gonna run home and make sure I can do what I just promised

Hi

I am happy that you got your bridge up and running. Your detailled explanation may help some other users with similar problems.

I believe in most cases it is quite easy to get the connection from a PC to a ProfiLux 3 over LAN. Just set verything to "auto" and hope that ProfiLuxControl can detect the automatically assigned IP of the ProfiLux. This works if your network is configured correctly and if DHCP-server is present (a DHCP-server assigns IP-addresses), usually part of the router.

But: If it becomes a little special - e.g. if there are several routers and network adaptors or a LAN/WLAN-bridge present some basic knowledge are necessary.

BTW: The LAN/WLAN-tutorial is only for our cards PLM-LAN or PLM-WLAN. The built-in LAN-interface of P3 is easier to configure - just enter IP or choose "automatic IP" - ready

So, I am having another issue. I tried to connect to the P3 from my home computer and it will not connect. I also cannot view the P3 settings by punching the address into the IE broswer window.

What do I need to do to control the computer from anywhere in the world? Am I missing somthing?

At home I launched Profilux Control 5.0.0.7 with these settings:

P3 Settings CONNECTION :
Name of connection: da Artsy Cube
Host-Name: 192.168.2.3
Port: 10001
Search automatically: unchecked
Search for SMS module: unchecked
Device address: 1
Type of connection: TCP/IP
Timeout: 5000ms

Do I need to change the settings on the home machine to see the P3? What about MAC address is this important when trying to do this feature? These are the settings on the home PC after running ipconfig:

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . : tc.ph.cox.net
Link-local IPv6 Address . . . . . : fe80::48cf:be9c:802a:e55a%13

This is a complete different topic and here is knowledge about networking and internet addresses necessary, it is not so easy!

To avoid a wrong picture: This is nothing special for ProfiLux - you would have to do this with any equipment you want to access from "outside"!

> you must differ between private adresses (the IP addresses at home, like 192.168.1.100) and public addresses which must be unique worldwide (e.g. 74.125.43.105 is the address of www.google.de)

Now you may wonder that you can type www.google.de in the address bar of your browser instead of this IP. This is possible with DNS - this translates a domain name to an IP.

What do you need now? A static IP - not very likely that you can get one - or a domain name from DynDNS. Then you must setup your router that incoming TCP/IP calls for ports 80 (for the webserver) and 10001 (for access with ProfiLuxControl) are redirected to the ProfiLux. Here in this forum are some threads dealing with DynDNS.
