Core X Chroma Ethernet dropping out on MacOS?

Hi Crew,

Hoping someone else has come across something similar.

Config:

• New MBP 13" (2019) running 10.14.5, did not import previous system, just created a new account and went forward.
• Core Chroma X (w/ Radeon RX 580 Saphire card)
• Single USB C connection

I've installed the Ethernet drivers from the Razer support site, but every 5-20 mins the ethernet connection drops. I can restore it by disconnecting/reconnecting the eGPU, or changing the physical NIC config from automatic to a set speed/direction, or back again.

The frequency of the dropouts is getting annoying enough that the workaround isn't working any longer. In an attempt to address the issue I downloaded and installed a newer driver from the ASIX website here: https://www.asix.com.tw/products.php?op=pItemdetail&PItemID=131;71;112

Unfortunately this also didn't solve the issue. I'm running off wireless right now, which works, but isn't optimal.

Any suggestions on where I can look for hints as to the issue? I've checked out the console for logs, but don't see any messages that indicate anything with the NIC. Could it be the USB-C cable (not using the inbox one, but also not having graphics issues).

Thanks in advance for any suggestions!

Here is detail on the driver installed:

 

Bumping this topic again to see any results. I've upgraded to 10.14.6, and the issue persists.

 

I've been suffering from the same issue on MacOs Mojave (10.14.6) with the latest AX88179 drivers (v2.14.0) on a 2018 MacBook pro. I'm using a thunderbolt 3 cable to connect. The GPU and other USB peripherals seem to be working fine, but the ethernet suffers from frequent disconnections.

 

The only workaround I've found so far has been limiting the network speed to 100Mbps - which completely stops the disconnection, but limits me to 10% of my local network speed - which is not an acceptable long-term solution.

This is most likely a driver issue or a hardware issue with the AX88197, as I'm able to maintain stable 1Gbps connections with other adapters on the same network setup (same cable, router, etc.).

 

Thank you for the quick reply.

Am I correct in assuming you requested a video and serial number in order to start an RMA process?

If so - I can now confirm that this is a driver issue, and doubt an RMA would be necessary or helpful.
I've loaded windows on my MacBook via bootcamp and tested the Core X Chroma's ethernet adapter extensively. I was unable to reproduce the disconnection on Windows. Note that the laptop, Core X, and all connected network components (cable, router, etc.) remained identical - but MacOs is plagued with disconnections while Windows is stable.

I've monitored the output of dmesg following a network disconnect (see attached below). If you still require a video, I'd be happy to provide it. Please let me know what additional information you need in order to resolve this driver issue.

Code:

AX88179: monitorLinkStatus - Link is down.

Not too worried about the colours, but would like the built in Ethernet to work. I can confirm it is connected via thunderbolt/usb-c. I have actually tested it with a different. year older MPB 13” with the same issues showing up.

It seems from other user’s posts that this is a shared issue, and seems to be isolated to a MacOS driver issue based on the boot camp test in this thread.

I’ll try to set the speed down to 100Mbps for the interim, however I’d really like to see the driver fixed.

Thanks!

 

Thanks for the workaround barad, I’ll give this a shot in the mean time. Also, I’m getting the same error logs in MacOS you are. Wasn’t sure if they were Ethernet related or not, but looks like they are.

 

Can confirm that @barad 's workaround does indeed seem to work. Hardcoding the NIC speed to 100Mbps earlier today and it seems to have no drops.

Of course, I'd also like to see this fixed to support the full speed of 1Gbps. Here is the OS link info for reference.

Code:

xxxxx:~ user$ ifconfig en8
en8: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=b<RXCSUM,TXCSUM,VLAN_HWTAGGING>

Experiencing intermittent drops every 5-10 minutes on a Windows 10 machine as well. Have updated all related and unrelated drivers, BIOS, etc. I've tried setting the port to 100mb to no avail and I've also tried other fixes such as turning off USB power management, selective suspend, etc. Contacted Razer support and they suggested I get a replacement.

 

I'm guessing you're suffering from an unrelated issue, maybe indeed faulty hardware.

Im my case the Gigabit ethernet is very stable on Win10, but utterly unusable on MacOs.

@Razer.Speedcr0ss - any update regarding when your SW team could look into this?

 

@Razer.Speedcr0ss I can also share some info, but I haven't replicated @barad's issue.

Please stay tuned!

 

Got the same issue with a 2018 Mac Mini and 2017 MacBook Pro 13" baseline model. The Ethernet connection drops a few minutes after boot, and not able to recover unless restart the interface.

I connect the Core X Chroma (with a RX590) to my Lenovo X1 5th gen and the Ethernet AX88179 work flawlessly under Windows 10.

I have been contacting Razer support for a few months but this is not yet resolved, I have given up using the Ethernet on the Chroma with macOS, I use the built-in Ethernet on the Mac Mini instead, I believe the issue is on the AX88179 macOS driver instead. Hardware should be fine (with Windows 10).
