Same issue, I played BF1 and 2042 on my Asus Tuf F15 which had a Wifi 6 card? (never bothered to check the specific model name/oem) worked flawlessly without issues.
just got a Lenovo Legion with an Ryzen 9 8945HX & Realtek 8299AE Wifi 7 PCI-E NIC, and same symptoms as everybody else, my network gets bricked after running game/connecting to a server for 1-2 minutes, only gets fixed by disabling and re-enabling network card in Device manager, tried all the possible troubleshooting steps I could think of/come accross, updating drivers, closing all background apps (even Vanguard anticheat to see if it helps) Updating, Uninstalling and Reinstalling Javelin anticheat, changing DNS settings to Google DNS, using Cloudflare Warp, chaging my network card's settings in Device manager properties, Disabling AMD-V (Virtualization) from Bios and disabling all Virtualization settings in Windows, Disabling Core Isolation (Memory Integrity), Making BF1- 2042- Javelin anticheat an exception in Firewall+ Windows Defender, disabling all exploit protection settings in Windows defender in program settings for all 3 aforementioned... I could go on and on but I've tried virtually any troubleshooting fix that I can think of (outside of messing around with router configuration) without any luck, absolutely unreal especially when I play a million other multiplayer games without issues, even EAFC (same publisher same anticheat) works just fine, so what gives?
UPDATE**** WORK AROUND FOUND:
I've successfuly found a work around for people (like me) who have WIFI 7 network cards and are getting their internet bricked when launching Battlefield through EA APP, this has been tested with 4 play sessions so far with a lot of success, only issue I found was once I was getting the "Activate Battlefield" error when applying the workaround (Fixed by restarting pc, starting the game without applying workaround, closing it and then re-opening it with the workaround)
The Workaround is: You open EA APP, wait a second until everything loads normally, go into device manager, look for Network Devices, right-click on your Wifi/Network card, Disable device, and then wait for a second until EA APP goes into offline mode, open BF in offline mode (Tested with 2042, have yet to test with Battlefield 1, probably works with it too) wait for the game to load, once it launches, it should give you a "Internet disconnected error", once it does, re-enable your network card and close it, and then voila, you may play for as long as you wish without that issue.
I'd be happy to make a Youtube tutorial if the instructions are unclear, this is pretty much the only workaround/fix I managed to find in 1 week of troubleshooting, will be using it until EA fixes this terrible bug with their anticheat
Guys,
sorry still same issue after back and forth playing different games when i come back to play BF2042 or BFV still crushing and i disconnect to the network, now my BF6 is not showing the menu this is total **bleep**, i hate it.... F**k!!!!
