Our network nodes all updated to beta-1.3 without me realizing it, so congratulations on that.

They are still running the 21 kernel, and I was just wondering if I need to upgrade to 23.

Will kernel 23 nodes be compatible with nodes that aren't updated and still running 21.

Is there a changelog or list of updates/bugfixes for 21/or just anecdotal reports of improved performance. Will it be worth the effort to go out to the sites and spend the hour or so reflashing the nodes that are already installed ?


What is the exact URL of the image to be upgraded and/or any step by step procedures.
I flashed a node previously to the open-mesh image and I just wanted to know what to do to get the kernel 23 installed. Will it also include the beta 1.3 or will I have to update it once I install the image.

I know these questions are a little novice and I can probably find the answers by digging around (and if I do before someone else posts, I'll post them here).

Thanks for any help.

first off... can you reply to my posts related to "Gateway Node causes LAN internet connection to be down" topic? it would be helpfull!

briefly: kernel 2.6.23 has improved HAL/madwifi drivers and .23 kernel nodes are more stable, .23 images are available at robin site

but not updated to current release...
BUT
just in these days I'm testing an On-The-Air kernel upgrade which will upgrade kernel only and save all the underlaying settings as they are: so a node running r1421-21 will run r1421-23 maintaining its dashboard settings and parameters.

...stay tuned!

Assuming you have "Accton mini routers"

Hey there... I was in your spot about four months ago. I had some of the exact same questions.

With some of the earlier versions of the firmware I was having all kinds of problems getting my nodes to stay up. One of the steps I did was to update to .23. That in combo with other things helped to stabilize my network. All of my nodes are running .23 and are great.

Yes, .21 and .23 nodes can exist on the same network with no issues. One of the users on here has a network with 100+ nodes. Most of his are a mix of .21 and .23. The main thing is all the nodes should be running the same firmware version. This will ensure everyone is playing on the same field.

To reflash nodes manually use the instructions at open-mesh.com. Do a search in the KBA for flash and you'll see it. I use the Live Linux option since I don't trust windows when flashing nodes. Instead of using the links to the lzma and jffs2-64k files, use the ones from Antonios bloggin.it site. The urls are below to the places I'm talking about.

As far as flashing your nodes with the new firmware, if your not having any problems then I would wait will Antonio works on the new "live" update which will push out the .23 kernel to all the nodes automatically.

The forum has a ton of great info in it, but it can be hard to find. If you really want to dig into the nodes and see what's going on in the background then do you research on here. I would start in the

Great, I might just wait then for the On- the Air kernel upgrades.

Will this require me to be running the experimental firmware or will it get pushed out automatically to everyone running "stable" ?

Hi Antonio, i'm looking forward to the over-the-air kernel flashing, as a lot of people are.

I can't tell from your code if it only flashes to .23 if the current version is .21, or if it will flash to .23 if it's <> .23.

I hope it flashes to .23 if it's <> .23

several months ago, when these different kernel versions were floating around, i flashed all my nodes to 2.6.26

I now want to get them back to .23 to be on the same version as you are currently recommending.

I've done several manually but still have a lot running .26.

If perhaps you had not thought about checking for nodes with .26 kernel, i request that you take them into consideration and see that .23 is sent to any node that runs <> .23.

Thanks.

-Dale

Not sure about that one. Good question though. Smile

OTA kernel upgrade only needs an underlaying running version > 1416 and it doesn't matter if beta or test, .21 or .26... it will bring the node to .23 mantaining all the previous dashboard settings in the flashed node.

Nice.

Of course, it will be available "when it's done." But could you perhaps give us an estimate of how long you think it may take before you're ready to release this? days, weeks, or month+?

Thanks.

As we know Antonio, in a month we will be out of betas and stable, with tons of improvements... Smile
Robin flyes !!

Yes, i should learn to keep my mouth shut... when Antonio says he's working on something, he tends to mean he's working on it right now..... He's a busy guy!

Strange.

I reflashed three of my La Fonera nodes with .23 images from Antonio site. All upgraded themself to r1498-23/nO.

Since the .23 kernel switch, i have problem with signal strength. I connect to my node with the same room, but the strenght is low already. When I go to the next room, the link is very unstable.

The only change is the kernel underlaying and the switch to OLSR... I'm really confused.
