Reset your router to factory default. Router should then be automatically configured with 192.168.1.1. Use an ethernet cable and hard wire your computer directly to the router (don’t plug in to the uplink port on the router). Manually configure the computer IP address (on the wired interface) to 192.168.1.2. After both IPs are set, go to a command prompt (if using a PC) and type “ping 192.168.1.1” (leave out the quote marks). If you get a reply,both devices are successfully located on the same subnet. Then, open a web browser and navigate to 192.168.1.1. You can then configure the device as you see fit.
I believe that model is 802.11G. You’d likely be happier with an 802.11N or 802.11AC but it’s easy for me to spend your money. Good luck.

Most people don't have a internet bandwidth that would swamp a "G" router. I have a 6 mb internet input and run several laptops and 2 desktops along with a couple of phones. The only time it's noticeable is when I'm downloading a movie or some large file. I've even run two TV's on Netflix with different movies and nobody else cried about it. The feeling that you need an "N" router is just a sales pitch unless you have a 10+ mb line. People used to run whole businesses on a "G" router. Course they weren't doing movies unless everybody was on porn.

Another point,.... D-link is as good as anybody's unless they threw it against a wall. Most people can't tell the difference unless they are reading white papers on Cnet reviews. There may be a 2% spread from the fastest to the slowest and has more to do with antenna and placement than brand. I have a Netgear, but bought it because it was the cheapest on sale at the time.
