Can't take ownership of router
I bought a "new" router online from Newegg "out of box." So I'm assuming an employee logged in with their email or it was returned to the store. Either way, I cannot bind my tp-link ID to the thing. I've registered it and included my proof of purchase with ya. Ok, so I've reset it using the button on the back with a pencil, holding it in until the lights flashed and it reset. I've downloaded and installed newer firmware. Couldn't get that to work except with the backup and restore option, otherwise I get an "invalid file type" even though it's a bin file. Basically, I can use it locally, but I can't use it remotely. It tells me I "cannot login to this router since you are not a manager of it. Please ask the owner to add you to the managers list." Please tell me there's a solution that doesn't involve a hammer, or alternately, having to wait for a replacement.
To summarize. I am the owner, would you please tell my router that. Thank you.
