|Without knowing how you had it setup before, no, nobody on earth can help you set it up again.....at least, not to how you had it set before your little oops.|
Here's a tip for you..............when you do have it setup and working, look in it's management interface for a place where it will allow you to backup (copy) the router's config to your PC as a backup. Then, should you ever accidently wipe the config, it's a simple procedure to put the saved config back on it.
Since it's been reset to factory defaults you're just going to have to go through and set it all up again.
Not to worry, anybody who's had a computer for any length of time has had an oops (or ten.....LOL) and they're often a great way to learn things.
For instance, you've learned you should keep a copy of the router's config on a computer just in case...and I'll wager you'll never forget that after you've gone through reconfiguring the router.
