YouTube issues.
YouTube issues.
I currently have a fiber internet connection. YouTube struggles to stream HD videos on my laptop, but works fine on my phone. I’m confused about why this happens and it’s making me frustrated. On my computer, I can watch Twitch in 1080p to 720p, while streaming YouTube is limited to 360p or less. When I run CMD and ping for YouTube, here’s what I see.
I'm online via Wi-Fi or Ethernet. Your speedtest scores aren't available yet.
Check the command prompt for IPv6 status. If your adapter shows a fe80:: prefix without an IPv6 address line, IPv6 is enabled but inactive. Consider disabling it. Verify all IPv6 sources are functional by pinging websites like google.com and cnn.com.
You're experiencing connectivity issues with your Ethernet connection. Since your ISP didn't assist, try checking your router settings, cable connections, and network configuration. If the problem persists, consider restarting your modem or contacting your internet service provider for further troubleshooting.
It seems the issue might be with your internet service or equipment rather than your device. The problem appears to affect only YouTube on your phone while Twitch works fine on your laptop. Your ISP hasn’t provided any assistance either.
You're using HD videos on your phone via LTE, which means your mobile provider supports IPv6. If your phone connects to your WiFi but your PC can't reach the same router—either wired or wireless—then the issue lies with your PC's settings. If neither connection works, the fault is likely with your router or the ISP itself. Based on my experience, this often comes from a misconfigured CPE (Customer Premises Equipment). It might have previously set up an IPv6 tunnel before. I recommend checking your mobile device's IP address using "what is my ip address" on Google. If it shows IPv6, you're on that network; if only IPv4 appears, compare with your fiber connection.
Thanks for the update. Your phone isn't showing any IPV6 address, and after turning it off on your laptop, you should be able to view YouTube videos again.
