I need some help. I have had my DIR-825 for a year and half. Had a recent storm where power went out for just a little bit of time. My computer that is wired directly to the router keeps losing the connection to the router - unable to obtain an address. All of my other devices (that are connected via wireless) still hold the connection with no issues. I've checked the cable, unplugged/plugged back into the router, and it shows connection on the network card on the back of the computer.
I have used the system interface to ensure the address is a valid one. I have powered up and down the computer multiple times and have also powered down and up both the router and the cable modem.
What are the next steps ?
