Description (last modified by harald@…)


Using the excellent connectivity here on the terrace (very pleasant), I 
would like to report that L3 connectivity in the front left hand corner 
of Convention 2 (RTGWG meeting this morning) was very poor.  Using 
Windows XP/802.11b/g, I could see the phyical networks and connect to 
ietf ,ietf-cgnat or ietf1x (and indeeed ietf-v6only) at L2 but L3 
connectivity varied from poor to non-existent.  Acquiring an address 
took a long time and packet loss variied from 100% most of the time to 
maybe 20% fr about 5 minutes.  DNS service was intermittent and 
connection to mail servers in various locations timed out repeatedly.

I experienced similar problems close to the stage in Convention 3 yesterday.

I can confirm this for the middle of Convention3 too, at around 10:50:

Gents -

The connections were bad in c2/3 earlier today (many folks associated with the center of the room ap) but we believe this problem has been fixed.

If you continue to see poor performance, please advice.

We did some tuning in the ballrooms so we'll have to see in the afternoon

Convention 1 back right was working well in 13.00 session.

Convention 2 middle right is rubbish currently (though better than thsi
morning).  Audio Channel 2 comes and goes with useful bursts of about 15
seconds followed by a dropout.

A friend from TCD just came by and fiddled with the AP but it hasn't fixed
the problem yet.


Joel -

can you pull the number of associations for the APs in Con2?
