cound you send me the output of the following handlers:

read_handler lt.hosts
read_handler arp.table
read_handler lt.routes
read_handler lt.interfaces

read_handler wr/es/es_N.bcast_stats

where N=1,2

what do you mean that it works? Is that, from node A you can
see routes to node C?

This was a bug that should be solved since a few weeks. Are you using a
recent build?

In any case could you provide me with the value of the aforementioned
handlers
for your 3 scenarios?

Are you using openwrt or are you following the instruction for using
wing over a pc?

In the latter case the script in the repository uses only one wireless
interface. Could
you send me the file /tmp/clickd.click?

R,
