  • DSL modem resetting after switch to generator

Hello guys,
I am having a problem with my Speedtouch DSL modem, each time the electricity turns off or the generator turns on or the electrcity bounces the router resets taking 2 minutes to reconnect.

Any solution for that problem , anything i can buy to fix that ?
ps : i have it connected to my UPS

Thank you
since it's connected to your UPS
the router should not reset
is it a router or a modem? if its a router and you have cable, then the problem is on the resellers side, he doesn't have the splitter connected to a ups, i have friends with this problem
its the DSL modem
and when the electricity varies, it resets
try it without the UPS

see if it happens (don't worry the likelihood of anything happening to it without one isn't so much)

Or if you can, try another UPS.
Put large capacitor on the powersupply low voltage wires :)
Maybe will help.
How old is your UPS and when was the last time you changed your battery ?
its not old , 6months or so .
the Speedtouch is so sensible to electricity , i don't recommend it


edit: what is that capacitor solution , care to explain more ?
I have used a SpeedTouch modem for 4 years and that never happened. My relatives also use it and never happens , my neighbors use it and it never happens.

When power goes off the UPS should directly change to backup power, but for some reason it's failing ,causing the modem to restart.

Try your UPS on a computer and see if it's running correctly. Also when you first got it, did you charge it for 8 hours ? If not, than that's your problem right there.
what else is connected to your UPS?

the problem is simple, there is a change in the electricity inside the router when power goes off, the UPS is not able to hold the same voltage and thus the router resets. you need a solid UPS
@ph_black nuclearcat idea about the capacitor is a good idea
a capacitor is a device that charge electric energy , this electric energy will be given to the router for a short period of time until the ups/supply is reapplied.
just go to any electronics store and ask for a 4700 microfarad 50Volt capacitor
it has a cylindrical shape with two bare wires emerging from one side ,
one of them is marked with a line or a negative sign on the body of the cylinder it should be connected to the negative wire of the dc cable connected to your router
the other wire emerging from the cylinder is the positive wire it should be connected(soldered) to the positive wire of the dc cable connected to your router,

if this doesn't solve the problem you should use a diode before the capacitor from the side of the adapter.
