Re: AX210 low upload speed, but it does not occur constantly.

AntonP8O · ‎08-13-2024

Hello.
I have debian 12 with proxmox on my homelab server with asrock b450m pro4 and PCI AX210.
I have good speed link:

iw dev wlp1s0 link

But upload speed to low, see iperf from my PC with cable Eth connection to router and my homelab server with AX210:

But download result is good:

I don't understand what the problem is, since the problem doesn't occur constantly. While I was writing this message, the upload speed was restored:

Hello AntonP8O,

Thank you for posting in Intel Communities.

Upon reading this information, it is best to coordinate this with our team for further investigation. I will post an update once it's available.

Best regards,

Hello AntonP8O,

Greetings from Intel® Customer Support.

After reviewing the specifications, I have a few clarifications:

1. Could you please provide the make and model of the PCIe card to which the wireless card is connected?

2. Is the wireless connection functioning properly with Windows? According to the motherboard manual, it appears to support only the Windows operating system.

3. When did it start to happen?

4. Do you remember if this issue happened after a new OS update or Wireless driver update?

5. Were you able to have a wireless connection in a normal/expected performance before?

6. Is this the original adapter that came pre-installed in your system, or have you changed/installed a new adapter recently?

I will wait for your reply.

Best regards,

JeanetteC.

1. My Wi-Fi card AX210 is installed in my Proxmox server and is connected via Wi-Fi to the Huawei XD20 router. In this configuration, I have WDS (4addr) running, and I am experiencing an issue with low outgoing speed from the server. I replaced the Huawei XD20 router with a Xiaomi AX3000T (with OpenWrt firmware). My WDS (4addr) stopped working and the problem with low outgoing speed from the server persisted.
2. I have not tested it on Windows.
3. The problem appeared after installing this Wi-Fi card.
4. No.
5. No.
6. There are no built-in Wi-Fi adapters on the motherboard. I purchased it and installed it in a PCI x16 slot. For testing, I disabled WDS on the Proxmox server and the problem remained.

PCIe Wireless card carrier designs, regardless of the actual Wireless card used, are notorious for not working properly when plugged into anything other than a PCIe x1 connector. I suggest that you try moving it to your board's x1 connector and see if this alleviates the problem.
Hope this helps,
