Google Nest WIFI Issues

[gordonhunter]

Good evening everyone (from Scotland, United Kingdom)

I have the following network setup in my home...

Routers

Google Nest (located in living room)
Google Nest (located in family room - bridge mode)
Google Nest (located in home office - bridge mode)
Google Nest (located in master bedroom - bridge mode)

Network Switches

TP-Link TL-SG1008D (located in living room - has all but family room routers connected to it via LAN cables)
TP-Link TL-SG1005P (located in family room)
TP-Link TL-SG105 (located in master bedroom)

Particulars

TP-Link TL-SG1005P (family room) has the following attached
Port 1 - LG TV
Port 2 - Sky Stream TV Box
Port 3 - PlayStation 5 (PS5)
Port 4 - Cat 6a LAN cable routed to Google Nest (family room) LAN port

Google Nest (family room) has Cat 5e cable from WAN port (globe) to TP-Link TL-SG1008D (living room)
Main / master router is the one in the living room (assumed... I would like to know how to be sure).
Issue is that I initially get good speeds of between 300Mbps and 400Mbps when I do a speed test on the PS5 however at what appears to be random times there is degradation down to under 5Mbps and cutting out of the network in the family room whereby you will notice lights cycling on the Google Nest router (family room) such that downloads / gaming is very slow on the PS5 and streaming on TV or Sky becomes unbearable.

I do not know which information to provide you but happy to start somewhere in exploring why this is happening with the knowledge base and expertise of those involved with this forum.

Surely you are able to have the Google Nest system provide a diagnostic report somehow?

I appreciate the time and knowledge you guys may be able to offer.

Thanks in advance.

Kind regards, Gordon

It’s a bit unclear but are you using the mesh system to provide the links between switches or are the switches connected via Ethernet and the mesh nodes hang off these.

Either way perhaps a network diagram that also uses different colors for wired and wireless devices might help

Can you plug a laptop into the switch port the PS5 connects to and run a command prompt "tracert 8.8.8.8" without the quote marks?

And post the output please?

Hi... thanks for your reply... sorry it has taken a while to respond.

To clarify... the switches are connected via ethernet.

Hi... thanks for your reply.

I have a MacBook Pro with no LAN port on it... just USB-C ports.

Is that command for Windows or can it be run via MacOS.

I may have a USB-C thing that gives you a LAN port... I will be back.

So I checked the UGREEN USB-C adapter I have but only has HMDI, USB-A ports and Memory Card Slots on it. No LAN facility. My wife's MacBook Pro is the same.

However... she does have a work laptop with a LAN port on it. So I will ask her if I can use that to run the command,

It would be Terminal application on macos and the command would be "traceroute 8.8.8.8". This will show you the network path via WiFi though rather than replicating the PS5 connection.

The work laptop would be ideal. No harm in checking wired and wireless paths.

Is the inconsistent speeds a new issue or always been there since the home network was installed?

Who is your ISP?

Checked all laptops in the house... no LAN ports... so thats not an option.

I have used my MacBook Pro to run the command. I will upload image of results.

Until recently I have stupidly had LAN cables connected to WAN ports on two out of the four Google Nest Routers and I think that was giving me problems. I have now resolved that. However still getting slow down on the network. I reset things in my family room and get over 400Mbps speeds and then at an undetermined time slows right down and / or disconnects.

I am the one to have installed the network.

My ISP is Zen Internet.

SEE ATTACHED - Image of "traceroute" command ran from my laptop whilst connected to Google Nest router by WIFI in family room (note - main router is in living room and connected to fibre modem via its WAN port.

Sorry more questions.

Are you using the master google nest as your router or are you using another router?

If another router what type?

What do you mean by Google Nest (in bridge mode)?

As requested before can you provide a diagram so we can see how the devices are connected together.

It s potential that the devices are not using wifi, your ps5 is hard wired, the switch is connected directly or indirectly to the master google nest, that is then connected to the router or ont. No wifi in play?
(Again this is where a diagram helps us to help you rather than assuming)

I d suggest if this is the case you ll need to consider buying a couple of usb-c to ethernet adapters £10 or less from Amazon to help diagnosing the network as wifi will not really help if it’s a wired issue, it’s also important to try and differentiate between it being an issue related to the wan or lan sections (an issue on your home network or an issue on the router/isp side of things)

Hi everyone… thanks for your replies so far… I will get back to each and every reply… however… having read that CAT6a cables are more rigid and therefore susceptible to faults with the wiring if manhandled too much and given most of my network was fine apart from family room and for the most part getting good speeds I felt it could be a cable… so I replaced the CAT6a cable between family room switch and LAN port of Google Nest in family. It seems better… time will tell… getting 520Mbps via an iPhone on Speedtest app since I done that. That’s been faster than ever. So now it’s about whether it drops out. I am watching for the Google Nest status light to start flashing but for now it’s good. I am so tempted to get a LAN cable tester but no idea which one is good but not overkill for home use. Would love one that measures length of cable as apparently CAT6a degrades after 100m and I have a feeling the installer may have left wraps of cable in the cellar rather than terminate it.
