There is a major fault in the radio system of this bad laptop. I do not recall what you have tried so far, but my advice is to change the system a component at a time to find out which component is at fault. There are only three components that can be changed; - change the left-hand antenna and coax, - change the right-hand antenna and coax, - change wireless card. Test again after each change. Record the results. Identify the faulty component and replace it. Predictable causes of failure for each component: - antenna physical impact damage, - water in antenna case, - broken coax cable termination inside antenna, - coax cable twist, compression, abrasion or water damage, - coax cable connector physical damage, - wireless card connector physical damage, - wireless card electrostatic discharge damage, - wireless card water damage, - wireless card product lifetime or thermal cycle damage. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Interpretation is described in the Wiki page. To interpret further I would need to see the result.

If you didn't, one possibility is that the UUID in our database doesn't match the one actually in the laptop. This is corrected by getting the correct information using a new collection USB key.

Nothing should happen. You have to do an extra step to take full command: Shutdown the laptop, Insert the USB drive or SD card containing the developer key, or with the key on the internal storage, Hold down the '✓' (check) game pad key and turn on the laptop, a diagram of the game keys should appear with a message Release the game keys to continue, Release the '✓' (check) game pad key, and within ten seconds a Devel key Signature valid message will appear, with an open padlock icon, followed by Type the ESC key to interrupt automatic startup, Press Escape key once, and the 'ok' prompt should appear immediately. The laptop is now unlocked temporarily. If this doesn't work, try a different medium. e.g. USB drive: Make a directory called security at the top of your USB drive and copy the develop.sig file into it.

Re: WiFi Problem
Juan, There are many tools and methods to test with, to find the cause of the problem. You should be able to use all tools, otherwise it is more difficult for us to help you. Test with a developer key, and then remove it before returning the laptop to child. The developer key can be used on a USB drive, with an activated laptop, without disabling security. So please do apply for a developer key for these two laptops. Send me the laptops.dat file by e-mail. I may be able to give you a key with limited duration (e.g. 14 days). http://wiki.laptop.org/go/Collection_stick shows the process to use. Once you have unlocked laptop, I can lead you through some more tests: - check the antennas and cable, using http://wiki.laptop.org/go/Antenna_testing - check for a kernel bug we know about, http://wiki.laptop.org/go/12757 - update to most recent operating system build, (you can always put it back to what it was later, but meanwhile you learn critical data; is the problem caused by old build), I agree with John's plan as well.

Software confusion aside, now you have my interest. You have tried using a known good antenna(s), and a known good card, and still saw the problem ? My first suggestion in a case like this is to replace the main antenna with a known good one and retest. The main antenna is the left-most one when looking at the motherboard, and is usually connected to the right-most connector on the WLAN card (labelled "Main"). The next suggestion is to replace the WLAN card. If you've done both of those and it still doesn't work well, look in /var/log/messages for any error messages from the driver (indicating a possible problem with the SDIO bus). Just about the only thing left to try is to measure the +1.8V and +3.3V at the card socket while Linux is running, there could be something wrong with the power switches Q29, Q37 and Q38.

Hi Kevin, can you perform the self-test -- described at http://wiki.laptop.org/go/XO_Self_Test -- and tell us whether you see access points listed during the wlan test? cheers, m On Mon, Mar 28, 2011 at 10:37 AM, Kevin Mauricio Benavides Castro wrote: > a few days I've been noted that in some XO, do not > detect wirelessnetworks at school but I made some supporting > evidence; on myXO but apparently when I run: > service NetworkManager start > > Setting network parameters...

Re: [support-gang] wifi problem with the XO
If the wireless network is hidden, then it may not be shown by ''my neighborhood'', but may be shown by ''iwlist''. See http://wiki.laptop.org/go/Hidden for more details. The OpenFirmware output will be most useful, as it excludes the operating system and Sugar ... and therefore I would be able to conclude whether the hardware is working correctly. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

If you mean iwlist or scan-wifi show the correct output, but ''my neighborhood'' does not, then it sounds like a Sugar problem.

What model of XO? What operating system build? To adjust my instructions, you can either: 1. use OpenFirmware, at the ok prompt type ok scan-wifi or 2. stop NetworkManager before the scan: sudo service NetworkManager stop sudo ifconfig eth0 up sudo iwlist eth0 scan -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
