Hi. The device it is connecting to is a laptop. I have tested with all the 4 lan ports and also other devices as well.

  @Gordonwv yes it was the cable after all! 
 

I changed the cable with an other one and it worked fine. I had a homemade CAT6 cable, I guess I wired it bad!

I have the same problem - Model AX73. When I connect the modem to PC directly, the speed was over 800Mbps, but when I connected it through the router, the speed was just around 80Mbps. The strange thing is when I upgraded/downgraded the firmware and did a speed test, it would give a high speed result for the first time. When I did the test again it would become slow again. I am sure it is not the problem with cable and PC because the direct connection had no problem. Any suggestions would be appreciated.

Hi @rickytong999 

 

If the speed is abnormal when connecting to the AX73 router, please go through these troubleshooting suggestions and make sure the negotiation speed between the PC and the router is good:

What if my Router Speed is capped at 100 Mbps?

Hi @Kevin_Z I have browsed through the related messages in this Forum and I think I have tried all suggestions. The router actually shows my LAN port connection is 1000Mbps but the actual speed is just 85Mbps constantly. Since so many users are having the same problem, hope the cause can be found and then fixed by a firmware update.

  @copyrght i alkso have a similar issue tried with TP Link AX 1500 modem with same CAT 6 cable and WAN is configured at 1000 MBPS and LAN 1 at 1000 MBPS. However, when i try the similar cable CAT 6 and with TP Link AX 1800 the WAN port is at 1000 MBPS but the LAN 1 port is capped at 100 MBPS full duplex. With so much of amount and hardly a 2000 rupees less modem is able to deliver better but not this. But box and advertisements shows 1*GIGABIT WAN and 4*GIGABIT LAN (but reality is 4*100 MBPS LAN)
