[OLSR-users] LQ Routing and 802.11b Link Speed

I have a network of about 20 nodes running olsr 0.4.9 where I am having 
problems.  For example lets say we have 3 nodes, A B and C.

A and B connect at 11Mbit/s, B and C connect at 11Mbit/s, however A and 
C are connected at 2Mbit/s

For some reason node C choses a direct path, and does not use B as a 
hop.  Going through B would be faster.  I can only guess the reason for 
this is because there are no lost packets so the LQ is perfect?

If this is the case, would the best solution be to set all radios to 
only operate in 5.5 or 11Mbit/s mode.  I may also need to modify my 
configuration to better fit the situation.

If anyone can offer any insight, please do.  Below is the olsr 
configuration I am using on each node. (note this configuration is for 
an HNA node, the others do not have an Hna4 section but other then that 
they are all exactly the same)
