Wireless adapter connects to network, however no internet connection

Hey everyone. This is my first time venturing for assistance. Typically I can fix things on my own but at this point I am stumped.

I recently got a new router(Asus RT-ac3200), and upon setting it up my desktop pc no longer can connect to the internet. My wireless adapter is the TP Link TL-WDN4800. I got the new router because a roommate of mine moved out and our previous router was his. So, I needed to replace it. He had the Asus RT-ac87u. This adapter had no issues while using that router but is acting up now.

Phones, video game systems, and my laptop all work just fine with the new router. So, I am rather certain the issues lies with my tower.

At this point I have installed the latest firmware for the router, reinstalled the adapter, and attempted to update the drivers on the adapter. However, every time I try to install the drivers it either says that the most up to date drivers are already installed, or it claims that they were installed successfully but the driver date and version number doesn't update when I check properties in device manager.

If anyone has any insight for me I would greatly appreciate it.

Thanks

try this:

go to network and sharing center. Under your network adapter settings, check IPv4 properties. Set properties to

(1)"obtain DNS addresses automatically",

(2) or try manually setting to 8.8.8.8 preferred, 8.8.4.4 alt.

Either should work.

check the frequencies, 2.4 or 5, my mrs comp wireless can only use 2.4.

With the DNS setting change(I had it on automatic but changing to 8888/8844 worked) I can now use the 2.4 band but not the 5 band. The 5 band connects, but there is no internet connectivity. This is odd because I used the same network adapter/comp set up to connect to the 5 band on the previous router.

Check the drivers advanced settings

So I tried to update the drivers. I downloaded them from TP link and after I install them it seems like it doesn't update. After restarting the system the old driver version number is still listed in device manager. Is there a reason that it would be resisting driver updates?
