The DIR-605L’s default IP address is 192.168.0.1; this address accesses the router’s administration screens.
The DIR-605L Default Password Doesn’t Work
Change the DIR-605L default password to something complex and hard to guess, because leaving it blank isn’t a good security practice. If you don’t know the password, reset the router to its factory default settings—the username and password will be restored to their defaults. Here’s how to perform a reset: Now that the router has been reset, all the custom options you configured, like the wireless password, etc., have been lost and must be reconfigured.
What to Do When You Can’t Access the DIR-605L Router
Like the default username and password mentioned above, the DIR-605L, like all routers, have a default IP address—192.168.0.1 in the case of this one. Also, as with the login credentials, you’re free to change the default IP address to something else. If you’re unable to access this router because you’ve forgotten what you customized the IP address to, finding it is easier than resetting the entire router. All you have to do is find the default gateway that a computer connected to the router is configured to use.
D-Link DIR-605L Firmware & Manual Links
Since there are two hardware versions, there are also two different user manuals. Once you’ve chosen the version (A or B), you’ll see a download link for the user manual. The default credentials and IP address mentioned above are the same for both versions of the DIR-605L, but other details between the two versions may differ. You can find the right hardware version for your DIR-605L on either the bottom or back of the router; look for the letter next to H/W Ver. on the product label.
