Your router assigns a unique IP address to each device connected to it if your IP address is listed as “192. 168. 0. 154”, “192. 168. 1. 155” or something similar, that is the IP address of your device, not the router. To find the IP address of your router, remove the last two digits from the number at the end of the IP address. For example, instead of “192. 168. 0. 154”, enter “192. 168. 0. 1” into your web browser.

The default username and password may also be printed on a label on your router.
