tp-link router password
my isp changed the password for the router. should i call again at the agency and tell them? Or he set the password worldwide similar to "admin". i tried the passwords "admin" and "1234" but it didn't work. is it my right to now the password? and if i want to reset my router to change the password than it wont work the internet ( the led from WAN will be orange ) and i will need to call back him to get it repair. ( i saw that he selected the ip to pptp but i had originally dynamic ip. if i reset the router and i don't want to call him back can someone help me reestablish my network (if i need so set an ip)
