Just had fibre installed and speed at the modem is 927/500 which has is fairly decent.

I have a run of Cat 6 coming out of the modem to a wall plate where one of my google wifi points is installed.

Speed at this point is 527/400.

That is the speed the wifi point is showing, not the speed it is distributing wifi at.

So there seems to be quite a big drop between the modem and first wifi point. Just wondering if this is to be expected or if I should be checking the wall plate connection?

The Google WiFi AP just isn't up to the task of a gigabit connection.

Having said that, you'd be lucky to hit that sort of throughput over a wifi connection in the real world, so it's a bit of moot point. You will most likely never notice under real world conditions, and if there's any use you have that requires greater throughput, then use a physical cabled connection.

how are you testing the speed at the wall plate?

Just using the Google wifi app which I assume measured the speed coming in. The speed to the connected devices is a differenteasure again

To be expected.

No wifi AP is.

I don't know exactly how the Google setup works, but 527/400 looks like the rate it has negotiated with a wireless client, i.e. your phone/laptop. This has nothing to do with the speed of your WAN link and everything to do with your wireless topography and the specs of the client.

You can probably confirm by checking the settings on the client.

Fairly sure the Google app is measuring the internet speed it is receiving, testing the speed of the wifi is a completely separate option.

If the test is RUNNING on the wifi AP, then there's no chance it will be able to move enough packets of the right size to show you gig throughput. That has NOTHING to do with whether the switch chips in the AP can move traffic to a client at higher speeds.

It sounds like what you are seeing is entirely normal.

Nope, it's an app that runs on the AP itself, so the throughput is irrespective of any connected client.

The test doesn't have anything to do with wifi other than you use the app to begin the test. The test is just measuring the speed coming in to the Google wifi point VIA the ethernet cable.

Are you sure it's actually going over the Ethernet and not wifi backhaul?

Yes, the Google AP isn't even connected to the modem via wifi, in fact I don't even know the modem wifi password as I've never used it, just have a Cat 6 running to one Google wifi AP which in turn broadcasts to another.

Just to further clarify, the modem is in a cabinet in the garage, first Google AP is in our kitchen, this is the one connected with Cat 6.

You don't understand what I am trying to say.

The CPU in the AP will be an anaemic little thing, suited to running a GUI and issuing commands to the switch and wifi chips. It _WON'T_ be good at high throughput to the software plane on that AP.

Ok I see what you are saying but there is probably a bit more to it, found a few threads about it.

End of the day complaining about speeds I am getting is probably a bit rich anyway given most people won't have anywhere near that.
