Hello everybody. Currently I'm running Openwrt on Raspberry and have tried a lot of different Openwrt builds. Constant problem with USB lan Asix 88179. I need your advice. thank you very much...
Power 3A for Raspberry and Power 3A for Hub USB 3.0

- I have tested from Linux version 5.4 to 5.10 all get the USB WAN error Asix AX88179. (Tested on 2 USB Lan Realtek r8152 runs relatively well, no problem) - When used for a period of 2.3 hours, the 2 usb Asix AX88179 automatically failed to connect to the wan and had problems. If I restart Openwrt, the connection is normal. (If tested with App Speedtest or website Speedtest, tested about 2.3 times, these 2 USBs suddenly died for no reason) Does anyone know how to fix this on Openwrt? I suspect due to Asix AX88179 USB. Thank you! (Power supply is excluded because I have tested various 3A power sources)
crashlog+conditions suggest nic hardware / load induced lockup... even more probable considering 5.4 and 5.10 manifest similar behavior...
i'd not exclude some arch + driver specific complications given the maturity of said chipsets, nor power circuitry as a factor
a little more info on how much data exactly you were pumping through each nic is just as relavent as time frames to crash... ( as is temperature I suppose... but not everyone has a thermal camera )
i think the first point of call would be to also reproduce with only a single usb nic inserted / used ...
(or save the trouble and use alternate nic/s?)
The temperature or power is definitely not because I use 3A and the fan is cool. machine temperature is very cool. My per wan speed is 250mb/wan and I use mwan3 to make 2 wan bandwidth into 1 Lan. Lan is equivalent to 400 ~ 450mb (After a few tests using the app or Speedtest website, 2 usb asix ax88178 is enabled and it is disabled. It seems that Asix ax88179 really has a problem. restart Raspberry .
I tested not using a usb 3.0 hub. Or just use 1 Usb Asix ax88179 but the problem is still the same. Check with the Speedtest application 3.4 times that the usb has a problem. Or leave it for 1.2 hours, the problem still occurs...
yeah... if there is an issue... I was sort of implying it's lower down in the power delivery layers... in the regulator ic's or components themselves...
rpi4 is known to interact in a non predictable way with hubs and power bleed also...
given the above... i'd go with another chipset / nic...
ue300 / rtl8153? is popular and has generally proved reliable for many users here...
at those speeds... vlans via a smart switch are also a reliable option... ( and bypass the hassle of having to handle boot usb -> nic interface reassignments )
I also consulted a lot of articles about Ax88179. and last response is This device should not be used for Raspberry + Openwrt to avoid problems. Thank you so much my friend!
Out of curiosity why are/were you using the hub? Given the RPi4 has two USB 3.0 ports and as far as I am aware ethernet adapters aren't that power hungry.
not sure about the OP, but I'd lean towards using a hub here...
mostly for the space/wear and tear factor... but the onboard power regulator is the achilles heel of the pi4... so if in doubt use a (powered) hub... but some hubs cause more issues than they solve...
a single usb->ethernet + a single usb3 thumb drive would probably be ok... and as you say 2 nics would probably be ok too...
but when hardware starts acting funny... it's definately one of the first things to try on these boards...
I replaced the Hub using a better one for the Asix ax88179a. But the problem is still the same. (The problem of lack of power can be ignored)
And I also tried 1 usb ax88179 to the Raspberry board, the problem is still the same, combining a lot of linux 5.4 > 5.10
Asix ax88179 tried on both PfSense and same error. It seems that Asix ax88179 is really problematic on Linux systems.
All 3 tests give the same result: Asix automatically dies after some time, you have to restart Openwrt, pfsense... Test App Speedtest or website 3,4 times Asix88179 will die on its own.
I firmly believe that the problem is related to the Driver that all Asix ax88179 currently on the market drive when running on Lunux. And I'm still waiting for a fix from someone in the community.
I had the same issue with the ax88179 adapter. Seemed to be triggered not by high throughput, but by a high packet per second rate. I disabled QoS (qdisc set to none) on the ax88179 adapter interface and that appears to have resolved the issue.

Same issue here - purchased a Cable Creations RTL8153 from Amazon that worked beautifully. Went to buy another and they had changed chipset to the ASIX88179 without listing the change anywhere. It failed to work no matter what I tried and the adapter was returned. For $15 it's not worth the hassle, just go RTL8153.
It did not permanently disable the problem. It just made it a little better. I switched to an RTL8152 USB Ethernet adapter and have had zero issues with it, even with QoS enabled.
