[Sugar-devel] ESSIDs and BSSIDs, NM and Sugar

2009-08-07 Thread Martin Langhoff
Following the "let's make Sugar more deployable" theme that Daniel started a while ago, I am looking at something that Reuben mentioned last week he discovered in the field. Apparently, the Sugar + NM combination we ship (on XO OS 802) cannot do the BSSID migration that you would expect. In other

Hello there, I´m writing you from Plan Ceibal - Uruguay. Here I´ve been doing some test on this subject trying to see what was happening with this "jumping" of the XO from one to another AP. Basically what I did was configure two AP with identical SSID, so the XO would see them both under the same

The instantaneous signal strengths change very quickly, as a result of micromovements of metallic objects, and the movement of people within the signal area. The firmware in the wireless components of the XO can and will make decisions about which AP to use at a rate which is dependent on the chan

Attached please find a program that can be run from the Terminal activity or the text console to display signal level, noise level and link quality at ten updates per second. It is useful for performing simple measurements of RF coverage on an XO associated with an access point. The levels are ex

Hello again people, I´m really happy to see you gave me some feedback. Lets see if I can clear out all points you've mentioned and put a beet more clear some other which I mentioned before with some lack of details >On 11 Aug 2009 James Cameron >The instantaneous signal strengths change very quick

Hello, On 7 Aug 09 Martin Langhoff posted that in presence of 2 identical SSID, the XO will always connect to the same BSSID. It happens that during the tests I've been doing lately, and wrote you about, happened exactly the opposite, the XO moved from one to another AP all the time. I'm saying t

Tomeu, to tell the truth I haven't done an equivalent test on this situation but it's in my to do list. Right now I'm using my day to day experience, in which I've been in presence more than once of a ESSID with different BSSID, for example my neighbour had the same wireless router than me (hence s
