Hardware Configuration:

• Router Model: TP-Link Deco X90

• Hardware Version: V1

• Firmware Version: 1.4.0

• Network Setup: Access Point (AP) mode

• Backhaul: Wired connection to the main unit

• Client Device: Desktop PC with MediaTek Wi-Fi 7 MT7925 Wireless LAN Card

• Operating System: Windows 11

Issue Description:
Despite the Wi-Fi adapter indicating a link speed of 2402 Mbps, actual download speeds are consistently around 1200 Mbps. This discrepancy persists even after ensuring all firmware and drivers are up to date.

Troubleshooting Steps Taken:

1. Firmware and Driver Updates: Confirmed that both the Deco X90 and the Wi-Fi adapter have the latest firmware and drivers installed.

2. Network Configuration: Verified that the Deco X90 is operating in Access Point mode with a wired backhaul.

3. Security Settings: Noted that WPA3 is not supported; currently using WPA2-Personal.

4. Signal Strength: Observed a signal strength of 79% at the client device.

5. Speed Tests: Conducted multiple speed tests using various tools and servers, consistently yielding download speeds around 1200 Mbps.

6. Wired Connection Test: Connected the desktop PC directly to the Deco X90 via Ethernet cable and achieved a maximum download speed of 940 Mbps, indicating a limitation in the wired connection.
