Cannot Connect to EA Servers – “NETWORK DISCONNECTED” Battlefield 6

When you encounter a network issue in Battlefield 6, I would suggest considering the following troubleshooting.

1] Prerequisite troubleshooting

STEP 1: Recall what you had modified on your device system shortly before you attempted the Battlefield 6 updates. Put it back to the status before the issue occurred. Verify if the issue recurs.

STEP 2: Delete the Battlefield 6 cache files in the Cache folder at C:\Users\[YourUsername]\AppData\Local\ Battlefield 6

STEP 3: Clean up the Windows Prefetch files.
Run "Command Prompt" as administrator, and run the following syntax.

del c:\Windows\prefetch\*.*/s/q

Then, verify Windows system integrity on the Command Prompt.

sfc /scannow

This will automatically fix if a corrupted file is found.

2] Troubleshooting

STEP 1: Unplug the network device.

STEP 2: Run "Command Prompt" as administrator, and run these commands one by one. This is so-called resetting DNS and network stacks.

- ipconfig /flushdns
- ipconfig /release
- ipconfig /renew
- winsock reset
- netsh int ip reset

Restart your PC after the last command completes.

STEP 3: Change your PC's (or any platform device's) DNS setting to set a public DNS server, either Quad9 or Cloudflare:

Quad9 DNS
IPv4 Preferred: 9.9.9.9
IPv4 Alternate: 149.112.112.112
IPv6 Preferred: 2620:fe::fe 
IPv6 Alternate: 2620:fe::9

Cloudflare DNS:
IPv4 Preferred: 1.1.1.1
IPv4 Alternate: 1.0.0.1
IPv6 Preferred: 2606:4700:4700::1111
IPv6 Alternate: 2606:4700:4700::1001

STEP 4: Plug in the network device.

3] Last resort

STEP 1: Back up first.
STEP 2: Run Windows's "Disk Management" tool.
STEP 3: Formatting the drive where Battlefield 6 is placed.
STEP 4: Freshly install Battlefield 6 - 1.1.2.0.

A little problem may go a long way, and this is something to be considered.
