Network Disconnected

Battlefield 6 – Intel I226-V Network Disconnection Issue

System Configuration

Motherboard: ASUS ROG STRIX B650E-E GAMING WIFI

Network Adapter: Intel Ethernet Controller I226-V

Operating System: Windows 11 Pro 26H2

Game: Battlefield 6

Issue Description

While playing Battlefield 6, my Ethernet connection repeatedly disconnects, resulting in a complete loss of internet connectivity.

The issue occurs both during the game's loading process and while playing. In some cases, the connection drops only a few minutes after launching the game.

Interestingly, this problem appears to be specific to Battlefield 6, as the Ethernet connection remains stable during normal usage and other activities.

Troubleshooting Performed

I have carried out extensive troubleshooting, following the recommended network adapter configuration settings and attempting several potential fixes.

The troubleshooting included updating the Intel I226-V network adapter drivers, reviewing and adjusting advanced adapter settings, disabling Energy Efficient Ethernet (EEE), testing different Speed & Duplex configurations, disabling Interrupt Moderation, reviewing power management settings, and running several diagnostic commands using PowerShell and Command Prompt.

I also tested a different Ethernet cable, connected the PC directly to the router (bypassing the network switch), and tried different router LAN ports.

None of these measures resolved the issue. The Intel I226-V connection continued to drop while playing Battlefield 6.

Alternative Network Adapter Test – Successful Workaround

As a further diagnostic step, I installed an external Nanocable USB-C 2.5G Ethernet Adapter, equipped with a Realtek USB 2.5GbE Family Controller.

Using this adapter instead of the motherboard's integrated Intel I226-V Ethernet controller, Battlefield 6 ran for more than 2 hours now and completed several game sessions without a single network disconnection.

This is particularly relevant because the same PC, router, Ethernet cable and internet connection were used. The only change was the network adapter.

Conclusion and Request for Investigation

Based on the tests performed, the issue appears to be associated with the integrated Intel I226-V network adapter, its driver, firmware or its interaction with Battlefield 6.

The fact that the problem disappears when using an alternative Realtek USB Ethernet adapter strongly suggests that the issue is related to the Intel network adapter or the way Battlefield 6 interacts with it.

I would appreciate it if the EA technical team could investigate whether there are any known compatibility issues between Battlefield 6 and the Intel I226-V Ethernet controller, particularly on ASUS motherboards using this network adapter.

I would also welcome any additional recommendations or technical guidance that could help identify and resolve the root cause

I have been having the exact same issue. I did the troubleshooting — with the ISP provider nothing is wrong, the router is fine, I have a great connection 10gb conection, in this case 2.5 gb board limit, LAN drivers updated, all other games and activities are running fine, except BF6 for some reason. I even reinstalled Windows just for a sanity check — no problems with other games and apps, just Battlefield 6. they keep marking it as solved but nothing is solved and i have seen many people ho did not have this problem before having it now as well.

Issue started after updating to Season 3 (patch 1.3.1.0, May 12). Did not have this problem before.

Two separate symptoms:

1. NETWORK DISCONNECTED on initial connection to multiplayer servers — error code 0:85008S:1605488263O:-2146631680Q. Works after hitting Retry, but fails every first attempt.

2. TIMED OUT during loading screen after selecting a game mode — screen freezes on load and the game claims inactivity disconnect.

Setup:

- Hardwired ethernet (Gigabyte AORUS B450M Rev 1 / Realtek Gaming GbE Family Controller, driver 1168.26.50.2025)

- Network is healthy: 0% packet loss, 273 Mbps down, 11.2 Mbps up, 42ms latency

Troubleshooting already completed with no improvement:

- Reinstalled game and EA App

- Updated NIC driver to latest (1168.26.50.2025)

- Disabled RSS and LSO via Device Manager

- Reset Winsock and TCP/IP stack

- Disabled IPv6

- Cleared EA App cache

- Verified firewall exceptions for BF6 and EA Desktop

- Adjusted MTU to 1492

- Switched DNS to Cloudflare (1.1.1.1)

Given the timing and the number of similar reports since May 12, this appears to be a server-side or anti-cheat regression introduced in the Season 3 patch rather than a client-side issue. Please investigate.

çözüm bizde değil superonline'da. statik ip alınca çözülüyormuş tabi. sorunları bitmiyor bu servis sağlayıcıların

Çözüm bulabildinmi aynı sorunu yasıyorum

I have the same problem, in fact I was be able to play the game for two weeks until today. It disconnected out of nowhere while i was playing and after that I couldn't login to the BF services. It probably caused by ISP if you are in Turkiye too. They put us CGNAT pool so either you should get static IP or use VPN. In my case, i don't want to pay 140TL/month for static IP, so I opened a ticket on Superonline's website and hope for the solution.  

Vpn fixed the problem but it cause too much ping. We need another solution.

having the same problem here. the game connects normally, but suddenly in the middle of a match I am disconnected and the message "server disconnected" appears. It started this morning, until yesterday I was playing normally

Is it the same error code? If so the only thing that has worked for me is using a VPN.
