Alright, I made another mistake.  I took one of my Linksys Routers that was flashed with the HSMM-Program v.1 and changed the settings.   I changed the node type from “Mesh Node” to I think Gateway Mesh.   Now  I can’t access the router no matter how hard I try.

Anyone have any ideas?

Thanks in advance.

That's an easy fix.

Your 169.x.x.x address simply means that your computer cannot properly get an IP address from the routers DHCP server. This holds true for Access Point mode because in AP mode, DHCP is disabled. In AP mode, you have to plug that Mesh AP router into a router in Mesh mode.

With the "non-fuctional" AP node plugged into your computer, set the Ethernet static IP address on your mac to 172.27.0.5 with a netmask of 255.255.255.0. Once you that, simply point your browser to 172.27.0.2:8080 (note the 2 instead of 1).

From the Help file located on a mesh node and a quick search for "Access Point" yeilds:

Mesh Access Point considerations

When a device is configured in Mesh Access Point mode it is essentially 'transparent'. You are going through the device to reach a mesh node, and there is no need to get to the device unless you wish to change its configuration. When the time comes to reconfigure a device in this mode be aware that it is not running its own DHCP server because that is the job of the mesh node it is connected to. You will need some other way to configure your computer's network interface. There are two ways to do this:

• Manual configuration
  Connect only your computer to the LAN port. Set your IP address to 172.27.0.100 and your netmask to 255.255.255.0. No other settings are needed.
• Automatic configuration
  You will need another mesh node that is using NAT mode on its LAN, and using the default LAN IP address of 172.27.0.1. Both of these are required, otherwise this method will not work. Connect both your computer and the LAN of the Mesh Access Point to the LAN of the mesh node.

In this mode the default IP address on the LAN port is 172.27.0.2. After one of the above steps you should be able to send your browser to http://172.27.0.2:8080/. If you used automatic configuration you should also be able to go to http://localap:8080/. Like the name "localnode", an automatically generated name exists called "localap" which is set to the localnode address plus one, but only when the node LAN mode is set to NAT. If you changed the default IP address of a Mesh Access Point you will have to modify these instructions accordingly.
