Wierdest thing.

I had a node which I flashed with the 2686 rev with olsr7 working fine while at my location. Located it where I had yet ever to get a connection and it was dead in the water, no connection even though I could see it, it wouldn't connect.

I just flashed a gateway with the newer 2686 olsr8 and took special note that this node brought itself online but only to the newer gateway flashed with olsr8..

Not complaining.. but am wondering why? Node is not seeing any units on 2683r7, just the gateway with 2686r8

r7 and r8 are (they should be) 100% compatible... but what are the versions you are running, rXXXX or RXXXX?

I'm asking that because of RXXXX versions run an alternate olsrd config file

so may be the case that you have a "mix" of versions and hence you see a couple of "islands" of nodes which share the same olsrd configuration.

Can you confirm?

(RXXXX test versions are available only from robin-mesh SVN

Might be channel related..
It lost its connection 33 minutes after the gateway node updated and changed it channel back to 11 from I assume channel 5 when it originally upgraded..

Will confirm..

Updates are being pulled from svn2.hosted-projects.com/ansanto/robin-mesh/update/, so which ever version that is

OK.. Heres where its at!

First.. I changed the entire network to channel 5 in the dashboard and patiently waited the requisite 25minutes (there should be a faster way to force channel changes on a node or gateway) anyway.. waited until all nodes/gateways changed channel to 5. Orphaned node came back online is properly routing now.. 1st time in 2 weeks.. (Problem has been driving me crazy with switch radios etc.. so assuming its location simply does not like channel 11 even though its signal strengths were way up there)

Second..

Previously orphaned node is: R2686-26/cO 0.5.6-r7
2 gateways and 1 node are : R2686-26/cO 0.5.6-r8
1 gateway & 6 nodes are at : r2683-26/cO 0.5.6-r7

All Gateways & nodes are inter-routing without issues now and checking in just fine...

Still want to do some tests for speed but dashboard is reflecting a respectable 7 to 11mbps between nodes and gateways and a SpeakEasy speed test though an r8 gateway came up at 5.5mbps and throught r8 node to r8 gateway came up at 4.8mpbs..

The only issue I'm seeing, and this could be temporary as the network settles itself out.. but have 2 nodes that are not connecting through their best Gateway choice (Strongest xmit/recv) signal paths.. don't know whats up with that.. perhaps it just needs to find itself..

Think I will bring the entire network segment upto R2686-26/cO 0.5.6-r8 and see what happens...

EDIT: It seems that any repeater/node that is still r2683-26/cO 0.5.6-r7 prefers to connect to the single gateway that is still at the same firmware revision instead of the newer R2686-26/cO 0.5.6-r8, even though the upgraded gateways are better signal paths... Just a FYI.. Confirmed I took down the offending gateway, upgraded it and nodes found gateways with best signal paths.

User feedback... system seems abit faster .. will upgrade all nodes to 0.5.6-r8 and let it be for a few days and see what feedback I get.

I am really trying to understand the differences between 0.5.6-r8 and 0.5.6-r7.. not that I'm having an issue with r8 but would like to appreciate the differences.. If anyone can address this for me it is very apprecaited. thanks



Got way too much time on my hands today!

If this turns out to be true then I don't think this is a good thing. Some changes seem to go in based on one person's suggestion, etc... What might be good for one person might not be good for the masses. Considering I've seen really no improvement in speed and only complaints of slower speed and now possible issue's intergrated differnet firmware version's I think atleast the olsr config should be put back to what it's always been, tried and proven. I know some people always want the latest and greatest, but most people want what is stable and can count on. I mean I've looked at a network that has r1523 and been up for almost 70+ days on 12 nodes, i've yet to see an r2671 up that long.

Just wondering if such changes to the core function of Robin should stay in branches and have feedback from there, rather then the main line. Kinda like the OLSR and Coova branch that are already in place.

agree, but ...what might be not good for one person might be good for the masses.

19 hrs and steady as she goes...
No complaints, disconnects or nodes dropping out...
Not sure if OLSR r8 adds anything to the soup though except some additional overhead, but working fine so far on EOC2610's and 1650's.
