[Commotion-discuss] Commotion meshing between DR1(Red Hook) and PR2, web speed vs. ping speed

[Preston Rhea]

@Dan I checked the ETX while associated with the gateway node, but not
the community center node - I (wrongly) assumed it would be about the
same as before.

@Ben I used speedtest.net, will try others next time.

I have a follow-up to this:

Lacking the admin password to the community center node
(MtPCWN_Paloma), I SSHed in and used the command line to upload the
sysupgrade DR1 Red Hook image to its /tmp directory and updated it
that way. When the node came back online, it had clearly updated the
software. Also:

- It brought up the open RHIWiFi AP, as the Red Hook image tells it
to, but I could never associate with this with either my laptop or my
phone even though I was clearly within range,
- It deleted the MtPCWN_Paloma open AP, but kept the
MtPCWN_Paloma_secure AP online (also couldn't associate with this),
- It brought back up the commotionwireless.net mesh BSSID, but even
though I didn't go through Quickstart and the Red Hook image doesn't
encrypt this, it wasn't associated with the gateway node and I
couldn't get out to the Internet. I tested that by plugging in via
Ethernet.

Now I have the admin password and I plan to go back this evening to
try and finish this. Do you think the problem with not being able to
associate with the AP has to do with upgrading from a late version of
PR2 via the sysupgrade image? Should I flash the factory image, and is
there a way to do this without having to use TFTP mode (that would be
really difficult in this case)?

Thanks for the help,

Preston
