Uninterrupted Back Up For Modem - Suggestion Required

[Saurav 22]

For my Internet I am using Modem Provided by Connect 12V Input & WIFI Beetel 450TC1.

During Power Cuts I am unable to use WIFI.

I need help to have some Cheapest solution for Providing power supply to both Modems.

I have invertor (Square Wave). But due to delay in switiching Modem restarts. It must not have disturbing Beeps like in UPS.

Pls suggest solution involving minimum Expenditure.

yeah, home UPS is the best solution.

I use Luminous brand home UPS and absolutely not having problem since last 5 yrs.

but had to change the battery once after 3 yr

I use Microtek Sinewave UPS without any issues since many years now... change/exchange ur square wave invertor to a sinewave one for a better overall experience and peace of mind...
