What is the right way to reset router?

I hooked up a Trendnet router wired to my Dad's computer. My daughter obtains wireless access to her laptop there. They had a power outage and now neither can connect to the internet. I do not want to have to travel there. Should I have them start by resetting router? Is the proper way to unplug modem first wait 30 sec, unplug router wait 30 sec, replug router wait 30 sec. and replug modem wait 30 sec.? Is this the correct order or is it mixed up. And also should either computer be on during this? And if not, does the wired one go on first? I imagine I may have to set up their network again? Please save me a trip, but both of them are not very computer savy. Thanks

 

unplugging the router will not reset it. There is usually a master reset on the back of the router (depending on your router). look for the manual on your router and it will (or should) show you where the master reset is.
By the way are they getting a error message, are all the lights to the router on, can you connect to the internet via of just the modem, can you log into the router???
