I thought I should create new thread here, sorry if it's already discussed but after buying 3 separate USB 3.0 to Gigabit Adapter (all as WAN) I encounter multiple problem wtih Openwrt Snapshot (kernel 5.4.x) below :
- Generic USB 3.0 to Gigabit Ethernet with Realtek RTL8153 chipset
Basically it's no great from the start, random disconnect and hardware not detected after getting wan
activity, similar problem also occured when in Windows 10 but after updating the driver from realtek
website the problem's gone. As for OpenWRT putting the adapter in USB 2.0 port solve the problem
although for those with fast gigabit internet, the speeds will be halved to max USB 2.0 speed.
- Generic USB 3.0 to Gigabit Ethernet with AX88179 chipset
At first all seems well but after a day or more (random but usually between 1 day) the WAN side
failed to get DHCP Lease and can only resolved with usbreset command, unplugging and
replugging the USB Adapter, or rebooting the pi.
- Tp-Link UE-300 USB 3.0 to Gigabit Ethernet with RTL8153
I had better experience with this dongle, but after a week or more (at least better than the previous
AX88179) similar problem occured when getting DHCP lease :
the solution also the same like previous adapter, usbreset, unplugging, or rebooting the pi.

I don't have device with stable kernel (4.9) to test (usually rpi 3b), but using Intel NUC and OPNsense with RTL8153 generic adapter seems stable enough, I do plan to use OpenWRT on x86 to test if in the future when I have spare time.
