[OLSR-users] Routes never added

[John Gorkos]

Ok, I'm no neophyte to OLSRd, but I'm stumped.

I recently had two routers fail in my 30 node network, so I replaced them with 
v3.0 WRT54G routers and put the latest OpenWRT on them (where the wifi 
interface is wl0, not eth1).   I put the SAME version of olsrd (identical 
binary) as is running on every other router on the network, but these routers 
won't make changes to the routing table.  Here is a snapshot of olsrd running 
in debug 1:

It will not create links with any router in the network.  7.1 is running a CVS 
version of 5.0, while everything else is running 4.10release, and the network 
is quite stable and successful.  But these two routers simply will not join 
the network.  They can see the other routers, and pass olsr packets to them 
(which I can see with TCP dump), but they never form links.

Here is the olsrd.conf I'm using:

     HnaInterval                 15.0
     HnaValidityTime             90.0
}

here is the ifconfig and iwconfig of the wifi interface.

I'm pulling my hair out on this one.  Fortunately, the routers are both only 
one hop away from a gateway, so I can put manual default routes in and the 
customer can get to the internet, but I can't do that forever...

Any help appreciated.
