Can MAC STUDIO M1 afford my 2000 mbps Internet speed??

I run a 10 Gigabit internet link to my network. even FAR older Macs have NO ISSUES keeping up with that sort of speed, but there are more ways to make configuration errors than before.

When I had Verizon FIOS 1 Gigabit Ethernet, I was advised (by verizon) that 'ordinary' internet speed tests did not work properly at that speed, and I needed to use the Verizon speed test for accurate results.

I realize that is not a solution, just another data point.

There is a way to ask your Mac your EXACT link speed, but it requires some Terminal commands. Since that may have general interest, so I will post in following message.

Actual Speed:

The good way to check the actual connection speed USED to be Network Utility, But in Catalina and later, Apple has deprecated Network Utility and now you have to use a Terminal command to see your actual connection speed. First, you need to know what en number the link is. then you use a command like this one, substituting the actual en number.

my main Ethernet connection uses BSD name en2 (as shown in) :

 menu > about this Mac > (system report) > network:

Aquantia AQC107-B0:

Name: ethernet

Type: Ethernet Controller

Bus: PCI

Slot: Slot-3

Vendor ID: 0x1d6a

Device ID: 0x87b1

Subsystem Vendor ID: 0x1d6a

Subsystem ID: 0x0001

Revision ID: 0x0002

Link Width: x4

BSD name: en2

Kext name: AppleEthernetAquantiaAqtion.kext

Location: /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleEthernetAquantiaAqtion.kext

Version: 1.0.64

Terminal command:

ifconfig en2 | grep media

with this as my output for 10 Gigabit Ethernet:

media: 10Gbase-T <full-duplex,flow-control>

For ‘regular’ Gigabit Ethernet, you should get this instead:

media: 1000baseT <full-duplex,flow-control>

Ethernet Errors detected:

To see if an Ethernet link is throwing more than a handful of initial errors, you can use Terminal command:

netstat -I en2

This is the resulting output. Counters are In-packets, In-errors, Out-packets, Out-Errors, Collisions. There should never be more than handful of errors from starting up, and in most cases, NONE.

Name       Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs  Coll

en2   8163  <Link#4>    00:01:d2:1a:00:dd   696697     0   484301     0     0

Reading the top line, If the link were running beyond its ability to run and be stable, for example it auto-speeded to 10Gb but the cabling could only reliably support 2.5Gb, we would see non-zero errors counts, and errors increasing over time. (and possibly, disconnecting)

So is your Mac Studio connected directly to your provider’s modem? If it is connected to a router then it’s likely the router has only 1Gbps WAN/LAN ethernet ports and you would need to upgrade your router. All networking hardware in the path must support speeds greater than 1Gbps.

So tell us how you are connecting things.

One thing to check: make sure your Ethernet adapter is the topmost in the list of network interfaces in your Mac's system preferences/settings. If you also have a Wi-Fi connection and it's topmost, your system will default to using that first.

If that doesn't help, post back with details; the version of macOS your system is running, who your Internet provider is, and the brand and model of network interface they provided you or you bought to use with their service. Then people will be better prepared to diagnose the issue and offer suggestions.

Regards.

That Ethernet cable could be missing a wire or have a bad RJ-35 connector.

I would test a direct cat6a or better Ethernet cable connection with no switches.
