So u people have no idea how dsl will work while power is off

maybe u can use a usb modem/router rather than a lan card one?

well some chinese DSL are avialble those work with USB power , like if you ligh goes but your laptop will be on as its on better so you can plug your chines dsl modem power source ( which is USB) in your latop and can use dsl without power hope so you got the point :)

like this modem :

go for small branded UPS, OR buss powered Adsl Modem.
