Xr500 can't connect to DNS server


Xr500 can't connect to DNS server

I was browsing the internet today, playing Destiny 2 and a few other games no issues. I stream on twitch around 4pm. Well around that time, i started stream, in 15 mins of streaming my internet just cut off. I go to troubleshoot the issue and says that - windows can’t communicate with the device or resource (primary DNS server). After doing troubleshooting I go to restart my PC and now it's saying (it’s trying to connect to a DNS server that’s incorrect or doesn’t exist). I've looked up youtube videos, reddit, this website everything to try and get this problem fixed and nothing has worked. Does anyone have any suggestions?

Could you try installing this hotfix firmware?


Also consider setting a different DNS address in the XR500, such as and, as your ISP DNS server may be at fault.
