Mac rebooted.

Down: 445
Up: 506

Will re-boot the Linksys router when the other half has finished her zoom call.

How can I get the same speeds via WiFi?

I suspect the zoom call might be eating some bandwidth and probably some CPU cycles from the router, so it may not reach the full capacity of the pipe unless your the only one on the connection (whilst your testing).

You can reorder the network connection preferences on the iMac to prioritise WIFi over the wired connection - however for the sake of simplicity just disconnect the wired network connection.

I don’t have a Velop router, but in general you need to connect to an SSID that using the 5 GHz band on WiFi. The router and iMac will negotiate the best connection speed - you should be able to achieve near enough 500 Mbps in both directions using your 802.11AC based network adapter that’s in the iMac.

Router now re-booted, no change ion speeds via ethernet direct connection.

Logging in to the Linksys router settings I see:

2.4 GHz band - Security mode = WPA2 Personal - WiFi Mode = Mixed

5 GHz band - Security mode = WPA2 Personal - WiFi Mode = Mixed

I'm not sure what would be the best thing to change, or how?

I'd prefer to connect via WiFi and get those same faster speeds.

New test via WiFi:

Down: 173.40
Up: 74.90

WiFi speeds can be impacted by so many variables.
Something as simple as living in an urban area with lots of close neighbours sharing the same WiFi channel can have considerable impact on wireless throughput/speed.

You have ruled out community fibre being the issue with the wired speed test.

Does your Linksys router allow you to name the 2.4GHz and 5GHz band separately? That way you can select which of the 2 you wish to use rather than the router deciding which is best.

You won't be able to get full speeds on the 2.4GHz band.

I have no idea about naming each band, or how to select which I am connected to. Anyone know how?

First, see which band you're connected to: option-click the wifi signal strength icon in the menu bar, and the details will be in grey under the network you're connected to.

Look for a line like this:

Channel: 36 (5 GHz, 80 MHz)

and tell us what you see.

The "5 GHz" is what you're looking for here; if it says "2.4 GHz" then we'll need to drill down to find out why your Mac chose that band.

The "80 MHz" is also important, as it's the channel width. If it says "160 MHz" then so much the better. However if it says "20 MHz" or "40 MHz" then these are narrow channels, which won't support the full available speed.

Again, given that info, it will be possible to suggest how to change your router's configuration to use one of the wide channels - that may be a setting like "Channel Width", "VHT 80". But let's first find the problem before looking at how to fix it

I managed to rename the 2.4Ghz channel, so I now know I am connected to the 5 Ghz. Speeds via WiFi are still slow, so for the moment I'm back on ethernet.

Would love to get WiFi speeds fixed.

Other things we'd like to see:

RSSI
Noise
Tx Rate
PHY Mode

These may indicate if the problem is with a broken antenna inside either your Mac or your router (given that they're right next to each other)

That walk through shows you how to change the ssid name ..

so you could do

MysticLady2-4ghz
and
MysticLady5ghz

that way you can choose which frequency to connect to

I think the router settings are generally fine, given that an iPhone can max the broadband throughput on speedtests.

But let’s see what the diagnostic from the iMac say…
