Approx. 4 years ago a tech installed d-link di-614+ 2.4GHz Wireless Broadband Router on my home computer. I have one computer linked and want to add another. I attempted to get into the site by typing the IP but it asks for user and password. I typed in admin for user but don't know the password. There is no way I can contact the tech because the company is out of business. What can I do? Or can I turn on my laptop (the one I want to add) and will it detect it? Is there another way to do it? Thanks for your help.

Try user ID: "admin". Password: "password". I've had D'lnk routers in the past and that's what they used.
Worst case scenario, hard reset and reconfigure your network.
Hope this helps and good luck to you. :-D

Thank you - that worked. Now another question - how do I secure the network? I've changed the password in administrator / tools but it keeps showing the default as 'unsecured network.' I an the network wizard using a flashcard as recommended and plugged it into the new laptop I want to add and it seemed to transfer under 'home computers' - but then when I click on wireless networks in range - it just shows the default as above. I didn't do something right - something didn't work. Any suggestions? Thanks again.
