I got a new USB ethernet adapter and use the native driver

I got a new USB ethernet adapter because the old one had lots of issues (hence the gist in the first place). But it still uses the same Realtek 8153 chip although am using the native driver though now, AppleUSBECM.kext

In terms of my previous issues, I remember that when I clicked the little lock in the browser to view the cert, it would crash my computer. But the disconnects that required a restart were the bigger issue. (personal reference link)

I'm currently running macOS Mojave 10.14

I am using a Dell U2723QE monitor which has an Ethernet port on the USB bus. It is a Realtek RTL8153 (0x0bda 0x8153) and the driver in use is the NCM driver (com.apple.driver.usb.cdc.ncm).

A bit of a downgrade from the Intel I210 chip in my Thunderbolt dock, but since its NCM it should be okay.

EDIT: Seems like VLANs are not supported.

Anyone noticing on 12.5.1 with Realtek 8153 chips that internet speeds are improved? I am basically no longer seeing a bottleneck like I did in the past and can nearly max out my gig connection now.

@43n79w

43n79w commented Aug 22, 2022

@dani190 throughput does appear to be better for the ECM driver in 12.5.1 but it still can't quite saturate my gigabit connection like the NCM driver can. But it's substantially improved and is within 80-100 Mbps of the NCM driver now. On my M1 Mac, CPU utilization is still a lot heavier in 12.5.1 with an 8153 chipset running the ECM driver compared to an 8156 chipset running the NCM driver. That would be expected given the difference between ECM and NCM. The impact may not make a practical difference to some people so it's great that throughput has increased. On my end, the CPU spikes with the ECM driver were causing audio glitches (e.g., small audio blips and dropouts) when trying to do other tasks that taxed the CPU heavily. These audio issues go away entirely for me when running the NCM driver.

dani190 commented Aug 22, 2022

@43n79w I wonder what they did to improve it but yes agreed. Practically speaking you probably won't notice it. I was going to try that pluggable 2.5g adapter until I saw comments above about airplay 2 issues.

@dylanneild
Copy link

@dani190 As an FYI - the Pluggable 2.5Gbps has other issues. I was seeing streams of interface level errors while watching a netstat stream with the Pluggable 2.5Gbps units; specifically I had a machine where Time Machine backups over SMB (to a Synology NAS) wouldn't complete successfully. As soon as the Pluggable was removed (for an Intel chipset Thunderbolt 3 gigabit adapter) the errors went away and the backup succeeded.

I think the Pluggable unit and the associated 8156 chipset devices "work" only in so much as they load web pages and do basic networking. Any load or complex networking seems to expose major issues with them. Not sure if it's the Apple NCM driver or the hardware.

Thanks so much for taking the time to do this analysis. I was lead to this thread after my Belkin Thunderbolt 3 pro dock USB ports would randomly stop working: ethernet, mouse, keyboard stop responding. Displays continue to work. Has anyone else experienced this as well? My theory is it is related to the Realtek drivers.

Just wondering if anyone knows how I can completely disable the Ethernet? Unload the kext?

Also has anyone found a reliable ethernet dongle? Preferably PCIe instead of USB?

@spmacdonald I think you are experiencing a broader problem. Back when I reported on 22nd April, my "Belkin Thunderbolt 3 Express Dock HD" was only giving me grief from its Ethernet port.

However, its Ethernet has been quite reliable of late. It's using the "...AppleEthernetE1000" driver. I'm confused. Could that have changed from the ECM driver? I can't be sure that I checked the driver back in April - only that it was unreliable:

the network would periodically stop working. Undock / redock was required to get it restarted

Before I bought the monitor, I used to use this Cable Matters portable Thunderbolt dock (the DisplayPort version): https://www.amazon.com/Certified-Cable-Matters-Thunderbolt-Compatible/dp/B08DYDV5DD

It has an Intel i210 chip, never had a problem and even supports VLANs.

Another option is the use the Apple Thunderbolt 2 Ethernet dongle with the Apple Thunderbolt 2 to Thunderbolt 3 dongle. I bought them on eBay and it also works well.

Just seeing the comments here about AirPlay 2 and the Realtek chipset. This issue is years old, and not strictly a Realtek issue. Thunderbolt 10GbE adapters which use the Aquantia chipset exhibit the same issues with AirPlay. It does not affect Macs which have the Aquantia chip built-in (like the Mac mini, or the Mac Pro.) Some sort of bug exists that prevents macOS from using AirPlay 2 with certain ethernet chipsets.

@thomasjpr I switched to an AX88179A chipset adapter (gigabit) and it works great with an NCM driver on Macs, but I noticed it didn't discover some of the mDNS/Bonjour services that Wi-Fi and ECM driver-using ethernet adapters can discover. I wonder if it's related.

What works for me to install the latest Realtek driver:

  1. Disable SIP: Hold down Command-R during startup - Once started, open Terminal - type "csrutil disable" - Reboot
  2. Install RTUNICv1.0.22.dmg
  3. During installation it will ask for alleviated privileges: Open System Preferences -> Security & Privacy -> Click "Allow"
  4. Enable SIP: Reboot and Hold down Command-R during startup - Once started, open Terminal - type "csrutil enable" - Reboot

Having installed the Realtek driver also solved the issue of my Philips monitor (with built-in RTL8153 NIC) locking-up my network while going into sleep mode.

You can check if the driver loaded well by running: System Information -> Hardware -> Ethernet Cards -> Realtek... It should say "/Library/Extensions/AppleRTL815XEthernet110.kext" on "Location".

I met same situation but not solved. I have 'system extension blocked ' pop iteam when installation but not "Allow" buttoun in "Security & Privacy".

I have just got a Realtek 8153 chipset based external lan card in type-c interface. The connection and system information shows that it is in giga lan connection. But the practical test indicated that it is actually around 100 speed of transfer.
The official realtek have no driver yet for macOS 12.6.1 with M1

Most likely the speed limitation or differ is due to the driver limitation.

@briantopping
Copy link

@simongcc There's a lot of details missing in your inquiry, but I can advise you that I have been using the Apple driver that ships with the operating system with no problem since ~12.5.

I'm wondering if you've tried it and if so, whether you might have some conflicting configuration that is stopping the Apple driver from working properly?

@simongcc
Copy link

@briantopping Thanks for your reply. After posting that, I just found out that I could have run a couple of other tests.
Because the tests I run was for the Lan connection speed transferring files to network NAS. The result could be falsy because there are many factors affecting this. I have done a few tests today with different lan cables by plugging in to the broadband modem directly and bypassing the router to eliminate all the factors. I use speedtest Mac App to get the result. It is around 900mpbs so it is quite acceptable with small loss and nearly 90% of the giga lan for an internet network with a giga lan broadband.

Sorry for using your time and making troubles.
The new type-c USB land card with Realtek 8153B proved to be working properly with the default Apple driver in macOS 12.6.1 M1
The brand that I have bought is from Taobao. I bought its usb type-c connector before which is of good quality so I give a try for other peripherals. My suspect was due to the to the negative comments that I have read in the product feedback during the purchase and diverted the integrity of the thinking and doing a rightful test.

I use speedtest Mac App to get the result.

This isn't terrible, but remember that your test results will be at the whim of your upstream provider. The best way to do this test is with something like netcat between two machines on the same network. Then compare that to the speedtest results you get. It doesn't mean that speedtest can always be discounted by the same amount though, your WAN provider will have good and bad days.

That's the biggest problem I've found is the connector quality on the cheap dongles. I had one dongle ruin a motherboard port on an older MacBook pro. Fortunately there were other ports, but it was disappointing.

Sorry for using your time and making troubles.

Not at all! We've all learned how to do this together. :-)

I have a very weird observation here.
I tested my RTL8153 against RTL8156B, and consistently got 700/600.
I recently bought a Banana-Pi R2 Pro to play. The board has an eth0 using RTL8211F transceiver. When I iperf3'ed across them, I got 940/920 consistently. I am wondering whether the problem is in the underlying hardware instead of the software.

Another upset nerd here 🙋 who can reliably make his system burst into flames with Airplay2 & RTL8153.

It's pretty clear little improvement from either Apple or Realtek should be reasonably expected but I cannot help myself:

  • Has anyone noticed any improvement w/ Ventura?
  • Has Realtek ever released DriverKit macOS drivers for any part?

Seems that 13.2 fixes the Airplay 2 problem. 🥳

Seeing this as well - 8156 chipset (NCM) AirPlay works in 13.2 / Ventura.

Oh that's nice! Thank you @tobsen @simplepanda for the report

On to upgrading to Ventura and some now due hat-eating…

I'm on an Apple Silicon machine on macOS Ventura 13.2 using an adapter with an RTL8156BG. It is using the NCM driver in macOS but as Realtek still have yet to get the finger out I cannot install Realtek's driver as it would need to be arm64e. Ventura just warns how the driver is legacy and needs to be updated by Realtek, changing the machines settings to reduced security, disabling SIP, etc doesn't work and it doesn't matter anyway as the binary is x86_64.

Due to this I am not able to take full advantage of the device as I can't enable Jumbo Frames or select any other Duplex modes bar Full with the NCM driver. On a previous Intel Machine running Monterey 12.6.3 I could get the Realtek driver to work by disabling SIP, etc. This would allow Jumbo Frames, etc to work. There is now no option on an Apple Silicon machine running the latest version of macOS to take full advantage of the chip.

It's unacceptable that Realtek haven't provided an updated firmware for this chip in the last 2+ years, they've had more than 2.5 years to prepare one for Apple Silicon. They shouldn't be allowed to sell or profit off of this latest chip of theirs if they can't even allow it to work with all advertised features on non-legacy machines.

There are two options;

  • Either Realtek update their driver for modern systems to finally address this issue.
  • Or Apple eventually update the NCM driver in an OS update which will allow the NCM driver to full take advantage of all of the RTL8156's features thus covering for Realtek's unacceptable incompetence.

I use a belkin adapter, macos shows it seems to be an 8153 chip, everything works fine... (This product is also sold in the Apple Store)
I believe it depends on whether the adapter is a better match to apple's driver implementation.
However, it does not appear to be designed for use with jumbo frame.
