I added the following to my device code last night:
server.setsendtimeoutpolicy(SUSPEND_ON_ERROR, WAIT_FOR_ACK, 10);
It didn’t help. My Imp did not reconnect this morning.
Hugo, what is the default “timeoutpolicy” if server.setsendtimeoutpolicy is not used?
I used Peters template. Looks like it’s working except I’m not getting any status back about why it disconnected.
Peter, thanks for the template.
@osherf think might the code example in wiki http://devwiki.electricimp.com/doku.php?id=electricimpapi:server:onunexpecteddisconnect
Peter’s template didn’t work for me 
did you try using the example as is? i tried that first. after it was working i folded my code around it.
it’s been consistently reconnecting for the last 4 days.
Yes, I used the example as is. Didn’t work for me.
This is strange… I used to power off/on the Imp to reboot. Last night I popped it out (April from Adafruit) and put put it back and the Imp reconnected this morning without a problem. Go figure…
…and it failed to reconnect today…
Installed new release (1e078ea - Fri Jul 12 10:54:48 2013). I will let you know. Thanks…
Good news! The imp reconnected this morning (WiFi was off for over 8 hrs). Thanks for the fix!
Please keep an eye on it and report any more strangeness (and the same for all the other testers who may be reading this)
We are experiencing similar problems. The only parts these different devices have in common are the Electric Imp card and the breakout board from SparkFun. Other parts are different types of relays, power sources, WiFi routers and so on.

Could you go into more detail on your power source, attached hardware, wifi router and internet connection for each of these above?
My Imp went offline overnight and stayed down for 6 hours. I unplugged it from the SD socket, plugged it back in, and it came right up.
Power source is a 12v DC wall wart with a Murata DC-DC power supply on the board. Hardware is a custom PCB with a variety of chips, mostly connected via I2C. Router is a Linksys WRT54G2 running DD-WRT firmware. Internet connection is a point-to-point fixed wireless using Motorola Canopy equipment.
How close is the WRT54? We’ve seen issues where these APs (being rather old) can’t cope well with the imp’s output power when it’s close, and they drop/do not connect reliably. Moving the imp further from the base station fixes the problem, as does using a more modern AP with a decent front-end.
Are you using settimeoutpolicy at all?
My Imp is about 4 feet from the WRT54G2, so maybe the signal is too strong. It has behaved fine for the last 24+ hours.
I’m not using settimeoutpolicy.
