Windows 10: IP conflict with Chromecast and Windows 10 Hotspot

Over the summer, I got brand new 2nd gen Chromecast to watch Hulu and other content from Youtube from my TV screen. It was no issue at first for the first few months. A month ago, I received a new TV montior to plug in my Chromecast and while it worked there the first time, from there I could not connect my Chromecast to my Windows 10 hotspot, which is connected to my DOCSIS modem through ethernet cable. I knew for certain this wasn't a monitor or Chromecast issue because when I set it back to my old TV monitor, the Chromecast still could not connect to the hotspot, and neither could my Android phone that I use to connect Chromecast to the network. I have followed many methods displayed in the Microsoft forum for situations like this. One of them including, enable internet connecting sharing on the Ethernet port. CHECK. Flushing DNS. Check. Entering in new network credentials for the hotspot. CHECK. Resetting the Chromecast. CHECK. Resetting network settings on my computer. CHECK. Went to check my command prompt and noticed my hotspot had a private IP address (192.x) configured with no gateway whatsoever. So, I went to the adapter settings on LAC*12 (hotspot virtual adapter) and changed it from DHCP to Static, and gave my hotspot an IP address and gateway in the same subnet as my Computer and Ethernet (public Class A address). That static configuration, and a manual configuration helped me to connect my Android to the hotspot from there, but Chromecast couldn't connect because it had the private IP address that wasn't in the same subnet as my new Hotspot address/gateway. I can't change that on the Chromecast, and I can't change the hotspot's settings to match the Chromecast without losing its connection from the computer and I cannot change the other two on the ethernet without losing my connection altogether. It seems here I am stuck in a triangle with no open window to it. I know this seems like a lot of information to read here, but the main issue is trying to get the Chromecast to connect to my Windows 10 hotspot, which is connected to my cable modem.


Many thanks to any input involved.

PS: And why am I getting two IPs in the same Hotspot router when I know it only works with one?

2 IP address conflict

Hi Jessirel,

IP address conflict usually occurs after defining a static IP address. To resolve, try following these steps:

Run the Network troubleshooter

1. In the search box on the taskbar, type Network troubleshooter, and then select
   Identify and repair network problems from the list of results.
2. Follow the steps in the troubleshooter and see if that fixes the problem.

If that doesn’t fix your connection problem, try these things:

• Reset the TCP/IP stack
• Release the IP address
• Renew the IP address
• Flush and reset the DNS client resolver cache

Run these networking commands in Command Prompt:

1. In the search box on the taskbar, type Command prompt, press and hold (or right-click)
   Command prompt, and then select Run as administrator >
   Yes.
2. At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
   • Type netsh winsock reset and press Enter.
   • Type netsh int ip reset and press Enter.
   • Type ipconfig /release and press Enter.
   • Type ipconfig /renew and press Enter.
   • Type ipconfig /flushdns and press Enter.
