I have an Exetel 50/20 plan, while I have no issue with the upload speed, I cannot exceed 26mb with the download speed using the Google Nest Wifi router except if I prioritize the device I am running the speedtest from. If I prioritize, I can reach 50mb download speed for the duration of the prioritization. 

I have tried using the Wifi and also Ethernet so directly connected to the Google Nest Wifi router and I have the same issue. 
If I use the Exetel router, I can reach 50mb consistently with no issue. 
I think based on my testing, there is clearly something throttling the download speed on the Google nest device. All firmwares and OS have been updated on all my devices to the latest available versions, I use primarily Mac devices. 
I have logged a support ticket with Google and despite looking at the logs, they cannot see an issue?! 
This sounds like a product issue to me, considering how many other threads I read in the community forums. 
Has anyone else experienced this and managed to get it fixed?

Hey there Ebok, 
I'm sorry for the late response, but wanted to hop in here to help you. I know that it can be frustrating and confusing when you are experiencing WiFi issues, but I'm happy to help. 
Do you mind answering these few questions to better assist you?
  1. Are you getting the expected speed when connected directly to the modem?
  2. What's the make & model of the modem you're using on the network?
  3. Could you give us an idea how does your network structure looks like? (e.g. Modem -> Switch -> Nest Wifi router -> Switch -> Wifi points)
  4. What other troubleshooting steps have you guys tried doing so far?
Let me know so that we can better pinpoint the problem.
Also, here's a couple links that I would suggest reviewing that have some great troubleshooting steps in them as well:

Thanks for the follow-up.
I have a basic configuration:
LBNCo modem > Wired to the Nest Wifi router > Bridged with a Wifi point located upstairs, although the router signal is strong enough that I don't really need the point in the house. 
So far, the focus has been on changing the DNS servers, from custom to Automatic to ISP. The ISP option seemed to have improved the speed, meaning I could get full speed 50mbps, but that lasted for 2 days and got back down to half around 26mbps. The devices have been factory reset, ipv6 and wpa3 left disabled, and this has not helped. We have also tried to change the SSID name with only one device connected to the wifi, that has not helped. We used different sites to perform the speedtest tests. 
It seems to be every time the network is restarted or a configuration change is applied, then the speed goes up for a while and goes down again or not at all, very sporadic, although every time I prioritize the device on the Nest router I am using, then I get full speed!  So it is clear that there are no issues with the wiring, the wifi signal, the channel, the DNS servers, it comes down to in my opinion to the router cutting in half the speed available for some reason. 
This issue has been logged with the support team and I am told it is now with level 3, still waiting for feedback. I can also see on other forums (e.g. reddit) that many other customers are having this issue so clearly not an isolated case. 
In the meantime, I am using the ISP router and get full download speed with no issue for now anyway. 
Are you able to help further from here?

Any update to this? This is a common Google Nest WiFi issue. If Google is doing this by design, perhaps to reserve bandwidth for other devices on the network, please just say so.

I have the same problem

Google Wifi LAN wired to the ISP Modem/Router (FTTH) 

  • Download/Upload speed wired to the ISP modem - 903 mbps Down / 273 Up
  • Download/Upload speed wired to Google Wifi - 89mbps Down / 250 UP

I have 10% of my download bandwich :O.

I don't have any problem with Netgear Orbi (800mbps/250mbps)

I just test... Thank you amazon for your service! 🙂

I’m facing a similar issue. Modem speed connected directly to device is 500 mbps, nest Wi-Fi slows to around 10 mbps download speed.  Is there a fix?
