Nest thermostat high ping time

fluffylittlemarshmallow — Tue, 08 Mar 2022 00:14:07 GMT

Hi,

I'm struggling to get my nest thermostat to talk to the cloud, it is reporting ping time of 2500MS

I've followed the nest guide to improving WiFi. First I had to change the SSID so that it only picks up the 2.4ghz band. But I am still seeing nest report stupid high ping times.

I've restarted everything, and checked on service status. I've moved it away from any potential interference

Signal strength 71 (out of 100), ping 2346ms (over 1500 is apparently a problem)

So I put it on a hotspot to my phone, over 4g and I get ping times reported between 800ms and 1200ms (which is apparently good for nest)

My broadband is 70mb, normally 36ms (Amsterdam) pings.

Any ideas on how to fix this?

HI @fluffylittlemarshmallow

@Anonymous has asked me to help you. What are the ping responses like if you ping the router?

Hi,

i'm pretty sure it's not that 😞 3ms ping.

Thanks, what about a traceroute to the address in the cloud?

Re: Nest thermostat high ping time

fluffylittlemarshmallow — Tue, 08 Mar 2022 15:57:47 GMT

I'd like to experiment with some of these settings if possible - is there a way to do this?

DTIM: 3
Beacon Interval: 211
Enable WMM APSD: Enable

Before I can answer that I would need to know which make/model of router that you have. I cannot see that changing the Beacon Interval will have any effect on this.

If you are getting a poor ping into the cloud, a traceroute would be much more useful as it would show where th problem was.

good idea, traceroute seems like the best next step, I just need to find out what server the next is trying to talk to.

router info :
- TalkTalk Sagemcom FAST 5364
- Hardware Version FAST5364 3.00
- Software Version SG4K100130
- GUI Version 5.6.1

so i am still struggling to figure out what the thermostat talks to, and what I should traceroute to.

however my problems have expanded.

google stadia (wired ethernet connection to router) fails to connect to games, but works fine on 4g vodafone network
this speed test fails to complete on talktalk, but fine on 4g - https://projectstream.google.com/speedtest

m=p8L0ob,qtq9Td,i5dxUd,m9oV,RAnnUd,Ru0Pgb,uu7UOe,ygtL7b,soHxf:385 WebSocket connection to 'wss://ndt-iupui-mlab3-dub01.mlab-oti.measurement-lab.org:3010/ndt_protocol' failed: WebSocket is closed before the connection is established.

(ping and traceroute are fine to ndt-iupui-mlab3-dub01.mlab-oti.measurement-lab.org)
this speed test is fine. https://speed.measurementlab.net/#/

I'll ask TalkTalk to get their networks team involved, but they may also request to see a traceroute as well.

Hi fluffylittlemarshmallow,

Do you have access to another router that you can test with?

Just checked the attic, and I haven't got any old routers anymore 😞

Morning,

Ok, would you like us to send a replacement router for testing purposes to rule this out?

Thanks

Re: Nest thermostat high ping time

fluffylittlemarshmallow — Wed, 16 Mar 2022 21:58:19 GMT

I would be happy to do that and see if it helps. Before I try a new router, perhaps I should do a factory reset on my current one, can I just do that?

(And apparently this might also force a new IPADDRESS)

So I dug a little deeper (raspberry pi, bridged network, wireshark) and found that the thermostat talks to a few different up addresses. All TCP.

35.190.54.210

35.169.85.41

103.99.150.43

54.81.179.208

On WiFi that last one (54.81.179.208) is unreachable. On 4g Vodafone it's excellent ping times.

And on WiFi I get connection refused for 103.99.150.43, but it works on 4g

10hrs after posting this, my thermostat is working and I can play games again 😄 yay!

(I assume that someone unblocked something or fixed a routing table somewhere, thanks!)
