Wifi Disconecting after 2 or 3 days?

[quattrodave]

Mine acted like that two different times.  Once when it was getting a bunch of electrical interference from the cheap power supply I was using at the time on my heater, and a different time that I think was just randomly lower voltage than it needed making it unstable.  Both times I had to power cycle the afterburner every couple of days to get it to connect again until I fixed the issue.  Besides those two periods mine has been rock solid and never disconnects.  Going on probably six months now without a reset.  Could it be getting shielded from the wifi somehow?  Like something metal in between it and your router?  Or something making electrical interference by it?  Are the other devices also on the 2.4ghz band or do you have other things on that band that are working normally?  Just trying to think of anything for you to check.

Thanks for your reply.  Interesting, so both your issues were power related.  I'm running my heater & afterburner from a reasonly large battery bank with a decent Victron charger attached, I'd be very suprised if mine was a low voltage issue, I've gone back through my Cerbo GX logs and can't find any low voltages lower than 13.4.  
It is possable there is an interference problem...  Any ideas if I can add some capacitors to the heater's supply to help filter out any spurious interference...??
