Model: Archer AX12  
Hardware Version: V1
Firmware Version: 1.0.25 Build 20230809 Rel. 54222
When connecting the ISP ethernet directly to my PC (without Archer AX12) with a category 6, 5e, 5 cables, it reaches 500Mbps

Similar problem: This post

Changed the cable, Forcibly enabled the 1000MB/S mode. On PC the connection speed is 500MB/s.

 

ISP has equipment:

Your ISP modem has 8 LAN ports. Have you tried to connect AX12 to a different LAN port of the ISP modem and check if there's any difference ?

There's a newer FW release for your device on its support page - here. Try upgrading the FW and check if there's any difference.

I can't do this because isp equipment is located in the entrance.

You have a problem that has to be solved. Either way it's a cable issue (most probably) or a router WAN port issue.

This kind of problem has been observed in many other router models and in most cases replacing the ethernet cable solves that.

In rare cases it's because incompatible ethernet ports (FW issue) of connected devices or a faulty ethernet port.

  @terziyski I believe that the problem is not in the cable, the problem is not with the WAN, the problem is in the correct detection of the speed by the AX12 router, because under the same conditions my computer detects it correctly and the speed is 500Mb/s

Hi, I have the same problem  my ISP 300Mbps, but WAN is Auto Negotiation Only 100Mbps.

fw:1.3.9 Build 20230728 Rel. 45716. Hardware Version: V1.2

If the wan is fixed at 1Gb full duplex it will not work.

Changing cables doesn't matter with the router none of them work on gigabit , as long as they work on laptops.

Checked everything, restarted, changed everything, no change.
