Don’t think have any RTL8157 based chips around.
Sabrent NT-SS5G Connects at 5Gbit, maxes out under 800Mbit down or under 450/450 both directions.
It is AQC111U chipset I believe (do not recommend that chip, killed 2 of the startech ones within a week of first use, the sabrent is unreliable last I tested it)
Plugable USBC-E2500: Connects at 2.5Gbit, maxes out at 673Mbit down or 475/519Mbit both directions.
Note that when on 2.5Gbit mutltigig switch these things will do 2.2Gbit or so down but only 850/850ish in both directions.
TP Link UE300: Great device managed 930Mbit down or 501/510 both directions. Still for sale years after buying my first 2 and it’s cheep. (only did 343Mbit down on a Balance 305, very impressed with B One so far)
Ugreen CM828 or UGREEN Revodok Pro 1061: 949Mbit down or 419/460Mbit. Less experienced with this device but it was sitting on the desk and wow did it preform. Can’t seem to find the chip it’s using and it’s sold under a lot of descriptions, also Revodok Pro 6 in 1 PN 45364.
All of these tests were done in a thrown together test environment, SMB, very large test files used, 10Gbit cards and 990 Pro NVME on both ends. It’s not going to be perfect, but it’s going to be close to what you can expect real world. The tests above were just speedtest.net through a RM551 modem.
The B One USB port and these devices were a limiting factor on the tests, the B One itself has more in the tank if you are on the physical WAN ports.
Single physical WAN to 1 LAN
2 server to desktops file transfer
2 server to desktops file transfers and a speedtest going over the RM551 through the Pluggable
