Wifi speed issue

Aloen287 — Tue, 04 Feb 2025 21:28:25 GMT

Hello. I use chromecast at home. My wifi network is 5 ghz. Channel in use is 38.

Chromecast connect with high speed like 250 300 mbps,then speed goes down all the way to 8 mbps or 12 mbps.I check it on the wifi router.

Solution is restart.

All other devices work fine-phones, android tv,notebook. Chromecast is 1 meter away from wifi router.

Hi @Aloen287!

Thank you for posting in the community. I'm sorry to hear that your Chromecast is not consistently getting full internet speed. I appreciate your efforts in taking those steps before. I'm happy to help you!

To help me find the best solution, I'll need to ask you a few questions:

What model of Chromecast do you have?
Is your Chromecast connected to the Internet via cable or wirelessly?
Does the speed slow down only when you cast a specific app, or all the time?
Does the image freeze or keep loading when you use your Chromecast?
What make and model of WiFi router do you have?
Is your Chromecast up to date?

Please keep me posted. I'll be waiting for your response.

Best regards,
Geremi

Hi @Aloen287!

Thank you for your response. Let's work together for a solution. To best assist you, I would like to ask some diagnostic questions to identify the root of the problem you are experiencing. These steps will help us isolate the issue and find a faster solution.

I would like to get the specific model of your Chromecast device, here is an article where you can find the different types of Chromecast devices.
When did the issue start? If it worked before, have there been any changes to the router or network settings?
When you're not casting, do you notice any messages about the internet connection on your Chromecast?
When you play video, is the video displayed on your TV buffering, lagging, or not playing properly?

Thanks for your kind attention; I will be looking forward to your answer.

Best regards,
Geremi

Hi @Aloen287!

Thank you for the details provided. I understand your concern about the internet speed your Chromecast with Google TV is receiving. Since you mention that you don't experience performance issues like buffering, lagging, or the video not playing properly, it's possible that the reading from your router indicates the bandwidth your Chromecast device is using at that specific moment.

If you have a Chromecast with Google TV (4K), for smooth, high-quality 4K streaming, we recommend an internet speed of at least 20 Mbps. This will allow your Chromecast to run smoothly and give you the best possible image quality.
If your device is a Chromecast with Google TV (HD), the internet speed requirements are lower, as high-definition streaming consumes fewer resources than 4K streaming.

It's important to remember that your Chromecast will not use all the available speed from your router. It only needs enough bandwidth to efficiently stream content, whether in 4K or HD.

Please keep me posted. I'll be waiting for your response.

Best regards,
Geremi

But I wrote that on low speed like 9 mbps youtube is not opening. So there is performance issue .
