Do you have a 10G USB-C 3.2 Gen 2 adapter available?
Long ago Aquantia introduced a USB 3.0 5GbE adapter. Since then USB technology has advanced significantly, now featuring USB 3.2 Gen 2 and even USB 3.2 Gen 2x2. I anticipate there should be 10G and 2x10G Ethernet adapters compatible with USB-C, but I haven’t found any. It’s even more surprising that a 5GbE USB 3.0 adapter isn’t widely available—despite the extra bandwidth USB adds, those dongles likely don’t deliver true 5G speeds. I’m hoping my AMD laptop can support 10G Ethernet, and while I’d need two USB 3.0 5GbE adapters and possibly bond them, it feels a bit awkward. Would there be any recent USB-C dongles offering 10G speeds using USB 3.2 Gen 2? Or perhaps USB 3.2 Gen 2 dongles with 5G capabilities?
They haven't been used much lately. The Aquantia USB 3.0 models are mostly ignored, only receiving a minor driver update beyond what came with them. From what I understand, after Marvell took them over, they were never handled again. It looks like the 10G issue stems from power usage—around 2-5W depending on cable length, and USB 3.2 caps at about 4.5W before efficiency drops inside the adapter. That means 10G adapters are essentially Thunderbolt devices.
Wow, I wasn't aware of how poor the support was. It’s strange when a USB cable gets slightly loose and automatically switches to USB 2.0 speed, only to revert back after a moment—especially when the connection is stable again. This particular dongle behaves differently; it actually causes crashes if the connection drops. On Linux, adjusting the cable a bit too much leads to a kernel panic and even a watchdog reset on the laptop. Except for that, it seems fine. I’m using it with a docking station, which helps maintain a stable link and prevents unexpected shutdowns. Personally, I think it works okay in my setup, but I doubt anyone would use it as a portable Ethernet dongle like I do with my gigabit ones in my backpack.
I own two Realtek 2.5Gbit cards and one 5G Aquantia, but none of them work as expected. It might be a faulty device. These Realtek NICs are known for being reliable despite their reputation for being budget-friendly and sometimes unstable. The main issue was that the Aquantia took a long time to boot, causing my NFS mounts to fail.
