TP-Link Archer AX53 WiFi random lag & ping spikes

FallenLove1314 — Sun, 01 Feb 2026 13:23:23 +0800

Hey everyone,
I’m hoping someone here has seen this before or managed to fix it.

My current setup:

Main router:
* TP-Link Archer AX73

2nd floor AP:
* TP-Link Archer AX53 (wired backhaul, AP mode)
* The AX53 is placed just outside my room
* Internet: 500 Mbps fiber
* Wi-Fi card: TP-Link Archer TBE550E PCIe Wi-Fi 7 Adapter

The issue is only with Wi-Fi on the AX53.

When connected to the AX53 via Wi-Fi, I randomly get:

* Sudden slow speeds
* Ping spikes / unstable latency (especially noticeable for gaming)

What’s strange:
* If I plug into the AX53 via LAN, everything is rock solid
* Signal strength is strong
* Backhaul is wired, not mesh
* The problem doesn’t seem to happen on the AX73 Wi-Fi downstairs

Things I’ve already tested:

* Different devices (same issue)
* Different locations near the AX53
* Confirmed LAN to AX53 is stable

So it really feels like the AX53’s Wi-Fi itself is the problem, maybe firmware, radio issue, channel width, or something similar.

I’ve attached speedtest / ping results showing good Wi-Fi speeds, so raw throughput isn’t the issue.
Despite that, latency will randomly spike, which is very noticeable during gaming or video calls.

Questions:

Has anyone experienced random Wi-Fi lag / ping spikes with the AX53, especially in AP mode?

Any settings that actually helped? (channel width, features to disable, firmware version, etc.)

Or is this just a limitation of the AX53 hardware?

I’m also open to upgrade suggestions if replacing the AX53/AX73 is the realistic solution — I prefer wired backhaul APs, not wireless mesh.

Note:
I understand that LAN will always be the best and most stable option, and I do use LAN when possible.
For this case, I’m specifically trying to improve Wi-Fi stability and ping consistency, so I’d really appreciate advice focused on Wi-Fi tuning or hardware limitations rather than just switching to LAN.
