One thought, to add to the mix...<br><br>How about designing the best solution for the 'deployment / school' situation, then offering a method for users to optionally 'tweak' the setting for their preference / situation. Like a sugar-control-panel option to 'show mesh enable/disable scan option'... then a "enable scan" or "disable scan" will appear in 'Neighborhood View'... as selectable items under "Mesh 1", "Mesh 6", and "Mesh 11" icons.<br>
<br>In a school/deployment situation, does the laptop always want to search for Meshes... even when the student is at home?<br><br>Oh, sorry.. there were several ideas there melded into one.... :-)<br>-Ixo<br><br><div><span class="gmail_quote">On 3/2/08, <b class="gmail_sendername">John Watlington</b> <<a href="mailto:wad@laptop.org">wad@laptop.org</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

is multicast. The student puts their computer to sleep (by closing<br> the lid)<br> and goes to school. Once they arrive at school, the last thing we want<br> is for their laptop to try to use simple mesh --- it trashes spectrum<br>
and makes<br> the school network not work, plus they won't see any of their friends<br> that<br> are (properly) connected through the school presence service.<br> <br> If we naively followed your suggestion above, the laptop would of course<br>
discover that the previous network state (simple mesh) was fine, and it<br> would never discover that there were centralized services available.<br> <br> This reply is intended to spark discussion about better fixes.<br>
<br> For example, how about only rescan when the laptop was in simple mesh<br> mode when put to sleep, or if an attempt to reestablish the existing<br> connection<br> fails ?<br> <br> wad<br> <br><br> <br> _______________________________________________<br>
