Realtek RTL8157 5 GbE adapters with 10 Gb USB interface - Wavlink, WisdPi

I asked and got this reply. Not sure if there is any difference or if they are doing some listings magic on Amazon.

Lol, their response makes no sense at all. Sounds like SEO or whatever the Amazon equivalent is, like you suggested.

Been running my two adapters via iperf3 for 5 minutes straight now and am getting sustained 4.7Gbps and they're a little warm (not bad at all). I had all kinds of weirdness plugged into a Belkin USB-C hub that I've decided is defective (and have an Anker alternative coming later today). Plugged directly into my systems the NICs are doing great.

Edit: Ran it for an hour straight and averaged 4.7 Gbps without a single drop.

These are running on Intel 11th Generation NUCs.

Both of mine show "Rev. A", though only the second one was bought under the "341" listing; the other was from AliExpress which didn't list anything specific.

Yeah, both are "Rev. a", but the difference was in the "-A" at the end of the model name, not revision:

340G: WL-NWU340G-A Rev. a
341G: WL-NWU340G Rev. a

So far the 341G working perfectly, no disconnections at all when reconnecting the cable, or turning off/on the TB4 hub it's connected to.

I see. In that case it sounds like mine are both 341G.

Were you having any trouble with the first one you bought?

Not that I noticed but I haven't used it enough to really say. Bought the second one on impulse considering how cheap they are.

I did some brief testing on an AMD 8845HS mini computer ( Beelink SER8) running Windows 10 LTSC.

I was limited by the 2.5gb switch I was plugged into, but both internet speeds and iperf3 tests were at 2.5gb, and in the hour I used the card to surf the net no issues were noticed.

I hoping to run my data center test tomorrow.

So it definitely looks like there are major issues using these Realtek 8157 based USB dongles with NFS.

I have been running the exact same configuration, but with OWC 10 GbE TB3 adapters, and the systems are rock stable.

The performance is a a bit better (10 GbE versus 5 GbE), but the price is wildly higher.

However, it looks like the only stable upgrade option from 2.5 GbE is to go to the older, more stable, 10 GbE TB3 solution.

A simple low-cost USB-powered set of fans is a good idea, as these TB3 devices tend to get a bit hot.

There are a bunch of OWC 10 GbE open-box units available, since a bunch of people end up returning these.

At about $145 each (10 GbE OWC open-box), compared to the $35 each (WisdPi 5 GbE), they are about 4 times the cost.

But a lower cost solution that causes multiple nodes in a Proxmox cluster to randomly lock-up and hang isn't much of a solution!
