I think the problems you have are related to bad links, not to OLSR.<br>
But olsrd could do a better job selecting less lossy links, e.g. a 2-hop cost=2 path would perform far better than a 1-hop cost=1.7 path.<br>
<br>
Is the distance between your nodes within a range what your wifi cards support?<br>

> Also when they establish the link, i have lot of packet losses and link is not stable for longer duration's. (I can Ping most of the nodes with variable latency like 6ms, 24ms. 43ms, 63ms, 6ms, 20ms from one packet to packet). I cant access most of the websites, tested with wget, after resolving the domain it says no route to host.<br>
