How to reset my dynalink router?

Hey, I was just making changes to my router and I was trying to change my router IP address from 192.168.1.1 to something else but now I am unable to access it.

I followed some blogs from like which told me to reset it but as per their suggestion, there is no reset button at the back of my router.

So if anyone knows how can I do it, it would be a great help. I am using the Dynalink router.
