Insufficient bandwidth for streaming with Fiber

Hi

 

I have 100 mbps Fiber and upgraded about 1 month ago (modem remained the same). Previously, I had no issues with streaming with 50mbps and no fiber. 

I've been receiving "insufficient bandwidth" notifications on Amazon Prime 4K streaming. Additionally, my cell phone's wifi is effectively useless when I am streaming something on the TV. This was not an issue before I upgraded service. AT&T speed tests show normal upload and download.

 

I have very few connected devices. Xbox (via hardwire) and my phone. 

 

I've reset/restarted the router and Xbox several times, with no success. I've also changed the ethernet cable with no success.

Hi @amirtcu,

 

You may need to update your firmware. Our newer Wi-Fi gateways have dual radios and band steering. You may need to check your TV specs to see if it works better on 2.4GHz or 5GHz. Check out the article to learn more about combined/ uncombined Wi-Fi networks.

Hi @amirtcu,

 

If there is pending update, rebooting the modem can resolve this. Press and hold the red reset button for 20 seconds. Our Wi-Fi Troubleshooting article has some steps that may help resolve the trouble you are having.

how do you update the firmware? 

 

Everything on my TV and Xbox are up to date. 

The Smart Home Manager shows no notifications under the steps you provided. 

 

Still having this issue.

I’m having a similar issue. Recently switched from Comcast to 100mbps Fiber. No issues the first few weeks; now I frequently get insufficient bandwidth messages on Amazon Prime, crashing HBO app, etc. I’ve reset the router to update firmware as recommended. I stream via Samsung Smart TV and no other devices except phones. Please advise!
