Strange Ethernet Issue

[deadiyshot]

So I've recently built my own pc about a month ago, and it's been working fine ...until now. Today when I booted up my system I saw a yellow sign next to my ethernet symbol, and what it read was limited connection. when I tried to open a page in a browser it was unable to do so. what is truly strange was when I opened a browser the yellow sign next to the ethernet symbol disappeared, and it read that I was connected to the internet, yet I wasn't. I was not able to open any pages and steam wouldn't work either.

I'm entirely clueless on what I should do about this issue, I tried turning off the router and modems then reconnecting them in 5minutes to no success. I also tried downloading the drivers onto a usb then onto my pc, but I'm not sure I did this properly. Anyways any help is very much appreciated.

System:
OS: Microsoft Windows 8.1 64-bit - OEM
MOBO: ASUS MAXIMUS VII HERO LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
LAN Chipset: Intel I218-V
Router: MI424WR (Rev E)
Other stuff (no clue we have 2 boxes connected to the router)
SPA2102 r (I believe this one is for the phone)
D-link DL-604

ISP: Verizon

Are other devices able to access the Internet? If not, check to make sure all of the connectivity lights are active on the modem. If they are not, and cycling power doesn't reset them, call your ISP.

If other devices can access the Internet, and updating the network drivers on the problem PC didn't help, try completely uninstalling the network adapter, then install the driver. Also, check the ethernet cable to make sure it is connected securely on both ends. And when the computer complains that it doesn't have a connection (that yellow triangle), click on the yellow triangle and tell it to run the network connection troubleshooter.

There are other things to try, but try those first and let us know if you still can't get online.

I did everything you had suggested to no success I get this after running troubleshoot: "windows can't communicate with the device or resource (primary DNS server)"

Trying putting in 8.8.8.8 as a DNS server. (Google public DNS.) Perhaps your ISPs DNS server is borked.

Is the DL-604 a router? Do you have two routers on your LAN?
