Slow Speeds in Wireless Router Mode on TP-Link AX10, Full Speed in Access Point Mode
Hello
I'm experiencing an odd issue with my TP-Link AX10 router and need some help. When I use the router in wireless router mode, my download speed drops to 30 Mbps despite being connected with a Cat 6 cable to my main ISP-provided Huawei HG8245X6 modem.
However, when I plug the same Cat 6 cable directly into my PC, I get 950 Mbps easily, and the same applies when I switch the AX10 to access point mode—I can get full speeds (950 Mbps) without any issues.
Here’s what I’ve tried so far:
- I've reset the TP-Link AX10 to default settings, but the issue persists.
- Tried both the WAN and LAN ports of the AX10, still facing the 30 Mbps speed in router mode.
- When I switch to access point mode, I get the full speed with no problems whether it be wan or lan ports.
- Tried disabling and enabling QoS.
The issue seems isolated to wireless router mode. I’ve ruled out the cable and ISP connection, as both work fine when tested directly with my PC or in access point mode. Any ideas on why the TP-Link AX10 isn't giving me full speeds in router mode, and how I can fix it?
P.S.: My main objective was to set a universal dns for my devices, which works in wireless router mode, but when I set the DCHP dns to 1.1.1.1, 1.0.0.1 in access point mode it doesn't transfer to my devices. So thanks in advance for any help!
Reset AX10 to its factory defaults - press reset button for about 10 sec. Don't turn on QoS.
Check your ethernet ports negotiated speed when in wireless router mode here:
It should be 1000mbps if you want to utilize its full bandwidth.
If negotiated speed is 100mbps then use another ethernet cable.
Your issue is quite similar to one described in this thread.
I connected the Cat6 cable from the Huawei modem to the WAN port of the TP-Link AX10 while it was in wireless router mode, but the speed on Speedtest.net was capped at 30 Mbps (even though Windows 11 Ethernet settings showed the port as 1000 Mbps capable). However, when I switched the AX10 to access point mode, I got 950 Mbps on speedtest. This applied to both the WAN and LAN ports when tested, meaning: when I connected the Cat 6 cable coming out of the Huawei modem to the WAN ports, tested it on speedtest, and then the LAN ports, and tested it as well, both got me 950Mbps.
Here is my diagram:
