I can’t use the maximum speed of my router, which is 1gbps on the local network, I’ve tested several cables, until cat7 I saw that this Intel i226-v driver has a lot of problems with Linux. I already forced the speed to 1gpbs but the system was very slow and bugged. I’ve tested other doors and nothing. My mini PC is when I like R7.
Can it be described more specifically? The i226-V We tested it for a long time and found no slowdowns.
I have done all the possible tests, I have already done several commands to force the router to stay with 1GBps but it will not. If I force the speed the system gets crashing, then I have to restart or try to re-configure normally.
Does your device not have the same problem when using other operating systems?
This looks like a classic 100 Mb/s fallback.
The NIC itself is fine, but the link isn’t completing gigabit negotiation, so autoneg lands at 100. Forcing 1 Gbps only makes it worse because 1000Base-T requires autoneg on both ends—forcing creates a mismatch and things feel unstable.
The quick way to isolate it is to check what the other end actually advertises; if 1000base-T/Full isn’t listed, the limit is upstream (cable, wall jack, or switch port). Try a short known-good Cat5e/6 lead straight into a different router/switch port, bypassing keystones. If the partner does advertise 1000 and you still link at 100, leave autoneg on, disable EEE for this link, and update the board’s BIOS/NVM—those two steps often stop the downshift.
For comparison, my ZimaBlade (Realtek RTL8125B, r8169) negotiates 1 Gbps full-duplex on a 1 G port; when I move it to a 2.5 G-capable port it links at 2.5 G immediately. Same story here: the link goes only as fast as the partner and a clean four-pair cable allow.
I didn’t try. I managed to run for 1GBps for a short period of time, but thinking it’s the router, I tested it on LAN 2 and also on the other port of my device and the same thing. It must be the Huawei router that has incompatibility with this Intel network device. It is inconsistent with the light of the mini PC until it stabilizes, now I turned on mini PC on the TV and the UN and it was consistent with the LEDs flashing non-stop. I’ve already bought a USBC adapter waiting to arrive because I can test it and on my notebook. With this adapter I will take the test. My router is Huawei WS7001.
My cable is Cat7, I have already tested all 1GPB trading settings and forced and it was not. The router is 1GBPS. It connects and drops to 100Mbps. Or it works very little time with 1GBps in self-trading, if I force the system gets too slow because the speed gets too bad. My motherboard is to WTR pro ryzen 7. I have already moved bios and everything is normal.
That pattern, briefly hitting 1 Gbps, LEDs flickering, then settling at 100 Mb/s screams autonegotiation trouble, not a ZimaOS bug.
The i226-V is notorious for EEE/downshift quirks with some consumer routers, and Huawei WS-series gear pops up often. Forcing 1 Gbps makes it feel “crashy” because 1000Base-T requires autoneg on both ends; forcing creates a mismatch instead of fixing the handshake.
What I’d do, leave autoneg on, test with a short Cat5e/6 UTP patch directly into a different router/switch port (many “Cat7” patch leads are stiff/shielded and can be flaky with consumer ports), and disable EEE on the NIC. Update the router firmware and your board’s BIOS/NVM for the i226. Your USB-C Ethernet adapter test is perfect: if it holds 1 Gbps solid on the same cable/port, it’s an i226 handshake issue; if it also drops to 100, it’s cable/port. A cheap unmanaged 1 Gb switch between the router and the mini-PC is a practical workaround that often “normalizes” the link.

It took me a while to buy an adapter to test. And it worked on my notebook but on my server zimaos not. I think it should be energy configuration. If anyone knows the command for me to see because also with 1Gbps adapter will not. The bios of my NAS have no energy configuration.
I can disable the power savings of both the CPU/GPU and the Lan port. It is still 100Mbps. With USDC adapter also does not reach 1GPBs. This should be limitation instruction with the motherboard. I’ll put her model here. AOOSTAR WTR PRO R7
@catadiel Did you find any solution to this problem? I’m seeing exactly the same issue: Aoostar WTR Pro (Ryzen) running Proxmox, connected to a Ubiquiti Cloud Gateway Fiber.
I even got a replacement under warranty because of this, but the new unit has the same problem. I tried updating/changing the BIOS and the network chipset firmware—no luck.
It really looks like a driver issue. On Windows with the official drivers the problem disappears, but running this machine on Windows feels like a waste.
I didn’t find a solution, I tried it anyway. I use it on wifi that beats much faster than on the cable. This must be a problem with Linux, you will have to wait to update the kernel. It is not a problem with the device.
I Have the same issue, (AOOSTAR WTR PRO R7)but everything works fine for me.(1.5.4)

I don’t understand, did you manage to use it at full speed?
I didn’t do anything, it was always like that.
