I typically use a Verizon MIFI 4620 for my internet access.  I now have a BBHN Nanostation M2 wired thru a Netgear GS108E wired to the RJ45 access on my PC (WIN 7 - 64).

The NM2 sees a friend's BBHN MESH node with internet access, thus when I look at my network, I have I-net access on both.  The wired MESH access seems to take priority over the wireless Verizon MIFI and sometimes they get confused and a web page may hang.

Is there an easy way to tell my network to put priority on the MIFI, or ignore the i-net access on MESH?

Not really that "easy" unless you are familiar with Windoes routing tables and device priority elections.

if you know those that would be the method.  Without knowing that  it really isn't too easy to do as both the mesh device and the wifi device are saying "route all traffic through me" (in fact you probably are routing most of your traffic through the mesh already as Ethernet ports are considered by windows to be "less costly" by default.

the recommended method at this time is to not connect to two networks at the same time unless you have these advanced skills otherwise you will hit issues like this.

Thanks - I kind of suspected that would be the case. I first ran into the problem in our Search and Rescue trailer running a program called SARTRACK. I tried wireless links to PCs that would share data, but also wanted i-net access to share the same data via Verion MIFI to the i-net. Found that our 800MZ radios would drop the wireless link, so hard wired to the LAN. Could not get windows to look at the Verizon, only the hard wired lan. thanks again.

It is an advanced network configuration task.  It's not hard if you know it but when you don't it's complicated.

Though now you have given me an idea for a feature, going to have to look at some things in the future see if I can make happen what I think I can make happen.

Are you comfortable with editing files on a node using vi?

I have not used vi. Am I comfortable? I have a spot to post pics of my successes, a trash can for my failures and an education from all of the above, along with a fire extinguisher. :) I would like to try. It is nice to have a graceful way to back out if things do not work. I have worked with many software adaptations with success. My knowledge of networks is a bit light, but have access to folks with extended knowledge.

Well if you want to give the following a shot:


use vi on the node to edit /etc/config.mesh/dhcp   (vi /etc/config.mesh/dhcp)

scroll down a few lines and make the file look as follows (use the i key to get into insert mode to type text) (your basically adding the two list dhcp_option lines)

config dhcp
option interface        lan
option start            <dhcp_start>
option limit            <dhcp_limit>
option leasetime        1h
option ignore           <lan_dhcp>
list dhcp_option        '121,10.0.0.0/8,<lan_ip>,172.33.0.0/16,<lan_ip>'
list dhcp_option        '249,10.0.0.0/8,<lan_ip>,172.33.0.0/16,<lan_ip>'

config dhcp
option interface        wan
option ignore           1

config dhcp
option interface        wifi
option ignore           1

use escape key then type  wq and hit enter.

After that go to the web interface, setup, save changes, reboot node.


While that is happening go to your control panel, network connections

For the wired and the wireless card go to properties> Internet Protocol TCP/IP (IPV4)  > Properties > Advanced > Uncheck Automatic Metric

Set the Wireless card to say 20, and the wired card metric to say 40.

Save the changes, and reboot the computer

Hint: you just told the computer that you prefer to use wireless whenever possible so now the wireless will be preferred over the wired port. However the change we made on the node for the DHCP file tells your computer "Hey I'm the best way to get to the mesh" 

If you mess up the router you can just press and hold the reset button (assuming it is version 3.0.0 or newer) for 15 seconds and the node will reset and reboot to just flashed status.
