anyways, the router lights go down too(except wireless and power indicator)

What do those lights indicate?

Do you have a separate modem? If so, what do its LEDs indicate during the outages?

 

[Akonam]

The lights are:- Power, 4 lights for 4 cables connected to it (they light up when I connect the corresponding cable to my computer), Wireless, DSL, Internet.

I don't have a seperate modem.

 

[TerryNet]

So the LEDs on the modem/router are indicating a loss of the DSL connection. That could be an ISP problem, or defective modem/router, or a problem with your (phone) wiring or a missing or defective filter. Remove all devices except the modem/router from your phone lines. If the disconnects stop, then add devices back one at a time until you determine which device or filter (probably the filter) is the culprit.
