AFAIK the only way to use the open11s support in the mac80211 stack on the XO-1 is with a thin firmware and the libertas_tf driver, is this option available for the new chip in the XO-1.5? I'm guessing this device also uses a fullmac driver. *: I am aware that OLPC's efforts in 11s predate proper support in mac80211 and thus were the only option. > - Ed > ___ > Devel mailing list > Devel@lists.laptop.org > http://lists.laptop.org/listinfo/devel > -- -Andrés ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

What's the network setup? Assuming you mean there is no infrastructure at all: The teacher will have to create an ad-hoc network (click wifi device in frame, click Create network) and the children will then have to go to the neighborhood view and click on that new network to connect to it. Then sharing works as usual, provided that all the laptops are close to each other. Yes, it's difficult in a classroom setting with young children.

See http://dev.laptop.org/ticket/9343 and http://wiki.laptop.org/go/Network_manager_0.7 and http://dev.laptop.org/~dsd/20090716/olpcmesh.patch The patch adds Ad-Hoc support back into Sugar 0.84 ... which would give you want you want. I think we have a terminology issue ... "mesh" can mean 802.11s, which as Ed said we aren't going to use ... you weren't using it on XO-1. In your case, "mesh" means Ad-Hoc networking between several XOs. You can manually establish an Ad-Hoc network between several XO-1.5's in build os32 using the following temporary procedure: 1. start Terminal and become root, 2. stop Network Manager, /etc/init.d/NetworkManager stop 3. configure the wireless device for Ad-Hoc, iwconfig eth0 mode ad-hoc essid xo 4. manually configure an IP address for each XO, ifconfig eth0 10.0.0.15 netmask 255.255.255.0 (change 15 to 16 for the second XO, and so on), 5. switch to the Neighbourhood view and the other XOs will be displayed in the usual fashion, 6. reboot to restore to normal operation.

If you have 25 laptops instead of 5, it's different. But for 5 XO-1's, this functionality works "out of the box". > How does the teacher do this - in less than 100 words and not one word > technical 0. Users open their laptops and just wait. If they look at the Neighborhood View (accessible by pressing the circle button with lots of dots on the keyboard) they should all eventually see each other on the screen , represented by XO icons. 1. The starting user launches Write. On the top of the screen, there is a box labeled "Share With:". The user selects "My Neighborhood". 2. Other users see an icon for Write appear in the Neighborhood View, in the colors of the person who started it. They click it, and a Write activity launches. This is the shared session. 3. The users are now editing a shared document.

Just like the mesh was on earlier releases. We already discussed this a lot in another thread. It should not be automatic. The thread is titled "[Sugar-devel] [Design] Ad-hoc networks - New Icons" The biggest headache about mesh is the cases where it sort-of-works, but not quite. Ad-hoc networking will be considerably less reliable than mesh was, for a few reasons: 1. In the mesh, everyone does their own beaconing. Sounds horrible but it actually works. In ad-hoc, there is just one beacon master. Due to cheap radios and interference etc, the beacon master will switch around frequently causing frequent network splits and communication failures. 2. This kind of situation will happen frequently: A <-> B <-> C B can see both users A and C on his network view. A can only see B, and C can only see B. B shares an activity. Both A and C join. However, anything done by A cannot be seen by C and vice-versa, because they are too far apart. 3. Another nasty situation A -- B A and B are outside of radio range, but are both setup to start an automatic network named "olpc" So they both setup their own ad-hoc networks, both becoming beacon masters. Another laptop "C" comes along A <> C <--> B This laptop can see both of these independent laptops (each having its independent network). It can join one or the other. It cannot join both. Hence this XO can only communicate with A or B, but not both (even though the range is OK), and presenting this choice in the UI would be nasty. Ad-hoc will work well for the cases where the children get together in a small space and explicitly create a throwaway network. If it is created automatically, I predict we will just get an unreliable mess. Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

We actively discourage anyone from using it, and I'm not aware of any successful applications of it except in test and demonstration situations. I suspect you are, like many, many people, confusing mesh with ad-hoc networking and collaboration, as was mentioned earlier. Mesh refers specifically to 802.11s networking, allowing XOs to act as relays forwarding packets from point A to point B where point A and point B are out of range of one another but can communication with other nodes in between. There are serious algorithmic problems with using this technology in XO situations. If you have 20 XOs in a classroom operating in mesh mode, they can collectively saturate the radio spectrum by all trying to "help" forward packets for each other. It's been hard to design a model that allows nodes in a mesh to know when to STOP serving as mesh nodes; and if we were able to do that, it would be again difficult to figure out when they should turn themselves back on. As far as I am aware, all XO networking scenarios currently in use in the field with the XO-1.0 can be replicated with XO-1.5. We sacrificed the non-working mesh capability in favor of a different wireless radio from Marvell that saves us about 150 mW, and that kind of power saving is much more valuable to our users. I also want to point out that in cases where 802.11s mesh operation is desirable, the Open802.11s stack (http://www.open80211s.org/) should be investigated. There's no reason Open802.11s software can't be used to make an XO a Mesh Portal Point (MPP). The only thing we're really losing in XO-1.5 is the ability of an XO to serve as a MPP in low- power mode, when the laptop is otherwise asleep. It would be great to get that working someday, but not today. - Ed ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

We have made some revisions to Deducto and Color Deducto based on the feedback received from Dan and Walter. Thank you Sir. We appreciate your feedback and guidance.

XO in 2 identical SSID scenario
Hello pals, some time ago I did some research on the behavior from the XO in places with more than one access point with the same SSID, and the results from this test weren't much god. As some of you may remember basically what my study said was that the connection jumps from one AP to another too frequent even if the difference in the quality (or level) of the signal is really big. In the same conditions, and even if both signals are strong a regular computers stays connected to the same AP. I even tried different SO on the XO and after thous test I'm confident that the problem is somewhere close to the net card driver or firmware. The first time I wrote to you about this someone else had said something on the opposite hand but then he never replayed about the topic again and most of the feedback I received were questions about distances versions and configuration (that's not bad, but eater is useful). I would like to know if someone else did some test on this field in order to share results and points of view. I also tried to contact people from Marvel but they never replayed, does anyone know a good way to get to them? Well thanks a lot in advance for any help you can provide. -- Andres Nacelle Montevideo - Uruguay. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

For instructions on installing firmware, see http://wiki.laptop.org/go/OLPC_Firmware_q3a13 ... in short put it on a USB device, attach battery and AC, and at the OpenFirmware prompt type "flash u:\q3a13.rom" If it doesn't fix it, could you use the diagnostic ("test /keyboard") to figure out for us: 1. exactly which keys ... (there are two hand keys; are both affected?), and on which XOs, 2. whether the intermittency is dependent on the fingers being used, 3. whether the intermittency is dependent on flexing of the case or keyboard area, (there's a cable involved, and it may be a cause), 4. whether the problem goes away for a short time after a full power removal (battery and AC), (we had something like this on XO-1 B1, long since fixed, unlikely), 5. whether any of the keys get stuck in their active state.
