Question : Cisco 837 router factory defaults

My Cisco 837 router is goofing off and i want to set it to factory defaults. I would like to know what the factory ip address, username and password is so i can access it through the web browser. i dont have a console cable and dont have enough knowledge to use it anyway. Will this stop the router from goofing off or will i have to reinstall the OS.

You can make your own if you are so inclined- cut a normal straight through ethernet cable in the centre, and "roll" the wires. In other words, connect wire 1 to wire 8, 2-7, 3-6, 4-5. This is NOT a crossover cable, but a rolled cable. Then all you need is a DB9 to RJ45 adapter to connect it to the serial port on a PC, and you're all set.
