if you need a decent radio to deal with "near-line-of-sight issues", ubiquiti nanostations deal with it quite well ive got a 10k link near line of site thru trees and over beyond a 300 meter hill top and link quality is good.<br>

Hi Aaron,<br>
<br>
Yes - I think you are right. I've been playing around with the nodes this<br>
evening (I've asked people not to unplug them) and signal is the problem<br>
(its a non-line-of-sight problem really). I'm going to fix it early next<br>
week.<br>
<br>
But this [default route dropping due to poor connection] has got me<br>
looking at olsrd.conf settings again. Do you know if there is good<br>
documentation on the OLSR "TcRedundancy", "MprCoverage" and "LinkQuality"<br>
directives?<br>
<br>
I was reading up the man pages but some things confuse me (like it says in<br>
the olsrd.conf man page that, for MprCoverage, it "Defaults to 1 , and any<br>
other setting will severly reduce the optimization introduced by the MPR<br>
secheme". Whats funny/strange is that I had this set to 2 without having<br>
any idea why!<br>
<br>
thanks,<br>
