[Commotion-discuss] Pico's dropping signals in DR2

[Dan Staples]

Hi Dan,

Are you able to see if the router is rebooting during those periods 
when it drops connections? The top LED would be blinking. We've been 
seeing some DR2 reboot problems here with the network we set up for a 
conference. We disabled and turned off Serval on the nodes, and that 
has so far fixed the reboot problem...but it also prevents app 
advertisement from working. So we're going to try to find a fix for 
this as soon as possible.

I'm not sure about the problem where you can't connect to the internet 
or get the splash page. Maybe could you give us the debug output the 
next time that happens? It's under the Commotion menu from the web 
admin interface.
