EA Games Disconnect My Wi-Fi Adapter Every Time I Join Multiplayer

Hello everyone,

I have a serious issue with Battlefield and EA SPORTS FC 26. Every time I join Multiplayer, my Wi-Fi adapter disconnects completely and Windows loses internet access. This only happens with EA games. All other online games from Steam and Epic work perfectly on the same PC and network.

I have already performed a clean Windows installation, enabled Secure Boot and TPM 2.0, repaired Windows with DISM and SFC, reinstalled the Wi-Fi drivers, verified the game files, and disabled the EA Overlay, but the issue still persists.

My Wi-Fi adapter is an ASUS PCE-AX1800 with a MediaTek MT7921 chipset.

Has anyone experienced the same issue or found a solution?
