It was combination of some hardware issues and human issues:
- one fiber connection we have failed on one remote roof
- one ethernet jack was not done well and was losing packets
- one remote router had an ethernet port failure
- because of the ethernet port issue on OpenWrt & Ubiquiti (reported a
week ago) we have some things sub-optimally done through bridging, so
less fail-over and best route selection (so we had to manually drop some
links, because OLSR does not support route filtering like Babel does)
- so because of this initial hardware issues some people were trying to
be helpful and were modifying cables on the table and other stuff, which
made things worse and hard for us to debug
- and later on when we fixed all hardware issues, there was still your
QoS configuration from a day ago
So, yea, mostly bad luck. :-) And no WiFi issues, just everything else.
:-) WiFi links worked well from the beginning. :-)
So currently the venue has a nice uplink. Internally, the spectrum is
crowded, but we cannot really do much about this if we do not want to
use too much spectrum away from testing. I am not sure what channels
does the testbed need. We put APs on 1 and 13 for now.
