[WT-support] SOLVED -- Win-Test Networking over a mesh Network

[Bob Wilson, N6TV]

I just helped a fellow contester who was struggling to get a Win-Test
network to work again, after he had just "upgraded' his house to a mesh
network to get more WiFi range for new security cameras.

But both PCs were on WIRED Ethernet.  The IP addresses of the two Win-Test
PCs were 192.168.4.xxx and 192.168.4.yyy (where xxx and yyy are numeric
values I can't remember).  The PINT command between the two PCs worked
fine, but the Win-Test network did NOT work at all, no Gab, no QSOs, no
wtDxTelnet spots.

The IPCONFIG command revealed that this particular mesh network by default
had the Subnet Mask set to 255.255.252.0 instead of the typical
255.255.255.0.  So, instead of using the "normal" UDP broadcast address
that Win-Test calculates for you (192.168.4.255), I had to tell Win-Test to
use 192.168.7.255.  I needed help from AI to calculate the proper UDP
broadcast address for a LAN with a netmask of 255.255.252.0.  Fortunately,
it gave me the right answer.

Perhaps Win-Test can look at the current Netmask as well as the current IP
address so that the "Default" button on the Win-Test Interface
Configuration screen can do all the work for you.
