RE: IETF58 - Network Status

Yes, this looks to affect some models of cards and drivers more than other. 
Unfortunately, I fell this time in the unlucky category. The same model of 
card, driver, and OS that worked perfectly for many in many other similar 
events, including the last three or four IETF meetings made my work impossible 
this whole week with the wireless setting at this IETF network. On this respect 
this was - for me - by far the worst IETF since I am using wireless 
connectivity. Sorry guys.

Hi Randall,

I have been consistently unable to maintain a connection for more 
than a very few minutes, usually not even long enough to 
establish a 
VPN tunnel and fetch one message.  The 802.11 coverage comes and 
goes; the APs seem to vanish and I see nothing for a while, 
eventually the network comes back but only briefly.  This has been 

I can partly confirm your observations, since
I often see my driver reporting a signal strength of 0 for seconds.
The connection is somehow unstable as my log also reports

... and so on...
however, it seems also to depend on the cards firmware and driver,
so other people may have no problems at all...
Inspite all the problems, it works well enough to get things 
actually done.

the case in every session I've attended, as well as tonight's 
plenary.  It doesn't seem to matter if the room is crowded 
or empty, 
or where I sit.

I have attempted to only select the 'ietf58' network, but often the 
network vanishes and there are no networks visible; other times the 
only visible "network" is an ad-hoc calling itself 'ietf58'.

I wasn't often successful to reattach to APs after my card was
"hi-jacked" to ad-hoc cards announcing ietf58. Setting the 
essid again to the same value seems to do trick, however,
often I see signals of strength 0 (maybe the card is confused then..).
Furthermore, it happens often that I don't get an IPv6 address
directly after activating the card (maybe the RA doesn't get through).

Cheers,
 Roland
