After nbn upgrade to 500Mbps my Google nest is not upgrading to higher speed transmission

[krajr2003]

I am using Nest Wifi Router model H2D for few years. I was in 100/20 plan with my ISP and Nest device used to show 110MBps speed and 20MBps download and all my devices connected to it will show approx 100+mbps / 20 mbps download.

Now I got speed upgrade from my ISP to 500/40 - nothing changed in my setup, modem, all devices are at same location. Now Nest device is getting 520Mbps/ 40Mbps , i checked in google home app as well. 

But all the devices connected are only getting around 150Mbps DOWNLOAD only, but UPLOAD of 40Mbps across home.

WHY there is SO MUCH DROP from 500Mbps download? Is there any setting I have to change in my Nest device to increase speed? ISP confirmed no issue from their side, as Nest is received the 500/40 speed rightly.

I already did basic checks like power off, restart etc

Hi @krajr2003,

Thanks for reaching out to the community! I understand you're experiencing speed issues with your devices after upgrading your internet plan. I appreciate you sharing the details and the troubleshooting steps you've already tried. It’s helpful to know the Nest Wifi Router is receiving the full 500 Mbps speed, so let's work together to figure out why that speed isn't reaching your other devices.

To help me investigate, could you please provide the following information:

• What type of Ethernet cable are you using to connect your modem to the Nest Wifi Router (e.g., CAT5, CAT5e, CAT6)? You can usually find this printed on the side of the cable.
• Is the modem from your provider also a router (i.e., a modem/router combo unit)?
• Are there any devices near your router that could be causing interference, such as baby monitors, microwave ovens, or cordless phones?
• When you perform the speed test on your devices, are other devices on the network actively uploading or downloading?
• Could you please let me know the current firmware version of your Nest Wifi Router?
• Is the Google Home app up to date?

Once I have this information, I'll be happy to assist you further.

Best regards,

Debora

Firmware version 14150.88317. Yes my app is to up to date. My query is when I had 100Mbps speed from my ISP, my Nest router used to show 105 to 110MBps speed and all my devices used to get same speed. How come after I moved to 500 Mbps speed, my nest router showing as 530MBPs , but all my devices are only 150Mbps max.. same home, nothing new added. I strongly feel this is issue with Nest router or some settings to be updated?
