Hello, I am successful in getting my linksys based hsmm mesh setup working properly with N1MM Logger plus between two nodes.
My last issue to deal with is the master computer using both the mesh network via the ethernet port and a wireless network via the wireless setup on the laptop. If the ethernet cable is plugged in, the computer can't locate any internet websites. If i unplug the ethernet cable, then the master computer can reach internet websites.

It appears that when the ethernet cable is connected, the dns process favors the mesh dns setting.

both network connections are setup with dhcp and dns being set to automatic.
I even tried setting dns manually with no luck.

my issue is having the master computer being able to access an internet time server and any other internet needs while we are running multiple nodes and computer.

Only one computer in the setup will have access to the internet via the wireless.

All computers have the same version n1mm logger plus and each node has the latest firmware.

suggestions?

I have posted this request in the n1mm logger yahoo group as well.

thanks

I think this is a generic computer networking question - When you have one computer connected to two separate networks at once, how does the computer determine which one to use and how can you control it? 

I noticed this problem when setting up a node for the first time the other day.  When I was directly connected to a node I couldn't surf this website for the instructions I needed.  The computer was sending my http requests to the node instead of my internet connection. 

In a brief search, it looks like part of the solution may be to ensure that connection on the pc used for the node does not have a default gateway set.  I'm certain the experienced users here could give a definitive answer. 

Well, this is basically a routing issue.

If you obtain DHCP from both networks you most certainly get default gateway also, from both networks. This information make up the routingtable in your computer and the tricky part is to route correct traffic to the correct network. In this situation DHCP is not the best solution and since you only have one computer that needs access to the internet I would propose that you assign it static IP on the nic facing the mesh and obtain DHCP from your network facing Internet.

This way you have a default route towards Internet to start with. Then you need to assign a static route on the computer pointing out the mesh network(s) via your closest mesh node.

Also make sure that you´re assigned, from the DHCP server, DNS settings such as your mesh node is primary and f.ex. google is secondary.

If you want, you could also let the DHCP server deliver the mesh routes, but you´ll have to configure the DHCP to obtain this result.

This might sound a bit clumsy, but it is the way to go if you run Windows on your computer. If you´d run Linux on your computer you could, theoretically, implement a vector routing protocol, found in the quagga package, to collect the routing information from your closest mesh node.

You might, however, as I just thought of, have some luck with the OLSR implementation for Windows, but I have not tried that myself.

Ok, so after digging through the Networking articles in the FAQ it seems that you want your computer to have only one network connection and it should go through a node.   

For instance you can connect your computer to a LAN port on the node, connect the WAN port of the node to your home network and disable any other network connections on your computer such as wireless. 

That would also allow for all the other computers in the mesh to have access to Internet, but he only wanted the master computer to have access, as I understood it.

Ok.  From "Using the Web Interface":

The other option in the WAN box is the Mesh Gateway. When a node has internet access from either the WAN or LAN, that access is available to the node itself and to any computer connected to the LAN port. When the Mesh Gateway is enabled, this node will advertise to the mesh that it has internet access and will act as a gateway and provide internet access to the rest of the mesh. By default it is disabled...

I want to thank all the suggestions for my question.

I normally don't concern myself in having access to the actual internet.

But the directions point out to have the "N1mm master" computer have access to the internet for internet time service at least. I am not sure if there is access to other internet services that the master computer uses during the contest.

again thanks
