Hi! This is getting funnier and funnier. But I do not have an explanation for this.
So I have replaced Linksys with the new one. And attached to one of the antenna ports (numbered 0 in wlc) external omni antenna (nothing big). To the other port I connected original Linksys antenna. And everything is on the roof. An old picture (without second antenna and without new more strait antenna cable): http://wlan-lj.net/wiki/Tocke/Solar But what I noticed is that with original antenna connection is better (more throughput if I do a data transfer over the link). And with our system we plot graphs of average of all LQ in ILQ values reported by OLSR for all links to peering nodes of this node through time. So I switched from internal antenna to external antenna again to see how it looks on the graph. And I noticed that average LQ in ILQ switched around. Interesting. Then I tried setting one antenna as receiving only and the other one as sending only and the result was that both LQ in ILQ dropped. Then I inverted and both got high. And ETX got high. So if I use for receiving external antenna and for sending original Linksys antenna I get the best result. How is this possible? (I have attached graph.) The other thing I am wondering is about LQ in ILQ values. If LQ is good when I have rxant and txant set to 1 and ILQ is good when rxant and txant is set to 0, then if LQ means receiving quality and ILQ means sending quality (how much peers receive) then best combination should be rxant=1 and txant=0. But graph tells it should be just opposite. We have went through our code and are almost sure that we do not switch LQ in ILQ around somewhere. So is there a bug in OLSR (I doubt that in this case) or is there something else going on? Mitar
