Most devices are wired and thus on permanently, the only wireless devices a phone and an iPad.

 

But, it does give me a thought that if it's still rebooting after this factory reset, I'll disconnect everything bar the iPad, and see how that goes.

I had this exact problem and the fix was a new power supply for the modem - not the one that came with it. I was also running thru an (online) UPS

 

It also happened with my Arlo base station

Just a long shot, its not a microwave causing disconnections is it? We have that problem in a cafe, every time 1 of the microwaves is used is disconnects the wifi. It is a late model panasonic too...

Well, modem has a new uptime record of 2 days, 16 hours.

 

Running on street power, not the UPS.  Maybe it is related to the modem power supply?

Gah.  Can't find an easy monospace option.

It's normal for fixed wireless to drop the WAN and get a new IP on a 24 hours cycle, so that's OK. Looks like your UPS may be the problem then. Perhaps not outputting a decent sine wave?

OK, after operating fine for several days, I power cycled the unit thismorning, just to check it wasn't a fluke.

> Check you are using the right PSU... The specs are on the bottom of the unit (12V 3A I think). I know of people that upgraded and kept using their existing PSU which was underpowered and I have heard of that causing instability.

 

The SM(1) seems to have come with a 12v 1.5a power supply SM2 is 12 3A.     Does anyone know what all that extra power is being used on?

Could be that the (cheap) UPS is putting out a chunky square waveform as @RunningMan says, or dirty power, and the power supply is not handling it well (not enough capacitance), and not putting out enough amps all the time (say mid sine wave cycle) to keep the modem stable.

 

We have an SM2 with the 12v 3a power supply that I suspect has thermal too hot issues due to location, and it seems to be causing similar lock ups to what you report.

 

Has anyone seen similar power stability issues with the Smart Modem 2?  Say when powering from a 12v direct source like solar or battery?

 

Has anyone measured the actual volts and amps going into the modem, with a 12v midspan tap & meter?

 

Can anyone measure the 12v socket for pin size?

 

 

 

Thanks, David
