Hello
I have built an automatic backup system for my asus router, well its not much but two 12v relays on pcb board powered by the router's 12v adapter. So what happens is when relays are powered, my router runs on 12v provided by its adapter(adapter is used to power relays and router simultaneously). When adapter's power supply is cut off , relays connects my router to the battery supply. Although this system is quite good and works better than expected but there is a flaw in this. You must have figured out already!! You see when power is switched between adapter to battery and battery to adapter, there is a pause of half second (500 ms) before everything gets into place(relays taking almost a second to switch power), this make my router to reboot and it takes about 30sec to 1min before i can use the Internet again.
So either way please help me fix this so router doesn't restart when power source is being switched or provide me with better circuit where router stays always on even during power cut.
Regards!
Thank you
