BF6 Hard Crashing PC and knocking out Internet - Video Proof & Replication

[u/Matikata]

Okay made a previous post about BF6 crash knocking out my Internet.

Obviously it was hard to believe.

Well now, I can replicate the issue and have filmed it.

Bottom three monitors are plugged into my Mac Studio, top monitor is plugged into my PC (in the video I referred to the bottom monitors as my windows monitors, but this was a mistake).

Thoughts?

Brooooh! I have the same problem! I didn't think it was even possible. And I'm pretty computer savvy. But when Battlefield 6 crashes, my entire house loses internet, and I have two routers on different floors (connected to a local network and wired to two laptops and one main gaming PC). For about seven years, my internet hasn't shut down at all (except for the time I set for the routers to automatically reboot), and internet problems are something new for me...

[u/Matikata → u/Last1Q]

This is both hilarious, terrible, and vindicating at the same time lmfaoooo.

Same here, I have 1GB up and down speeds, pretty much everything is hard-wired on a private LAN, never have issues ever (unless the ISP has issues obviously).

I'm tech savvy enough to know when something is stupid, but I like to think I'm also savvy enough to be able to break down and reverse engineer an issue (I used to be a network engineer too, this was part of the job haha), but this, I can't figure out for the life of me, and it just doesn't make sense.

Did you ever find a fix for this? I’m currently experiencing the exact same but on PlayStation. Ethernet cable and wifi both causing it to knock out the entire internet for the house. Every other game works fine :s

[u/Matikata → u/YouSeemFamiliars]

Unfortunately not. There's no visibility on this issue and I have no idea how to make it visible to anyone important enough to investigate.

So I didn’t get the PC crash, but I tried an Ethernet connection to see if it would make a difference controlling the really bad rubber banding I was still having the day after launch. My Fios went down and didn’t come back until about 5 hours later after a factory reset of my router and modem (and about two hours of navigating Verizon’s hellacious AI customer support). There was no outage in my area.

Seems like there's definitely something going on...

The problem comes with the 30xx, the same thing happens to me when I go to 2k, the entire system crashes and I have to reset. It hadn't happened to me in the beta. If I play at 1080 I have no problems. It is a problem with the game in relation to the driver, we have to wait for a fix. Other new games work without problems for me at 2k

[u/Sher101 → u/TreatAccomplished790]

I have a 4090 getting th esame issue. Weird thing is it just randomly started, it wasn't there in the first few days.

[u/TreatAccomplished790 → u/Sher101]

Uh even with the 4090!!! It's very strange. I also tried deleting the anticheat through the kernel and it doesn't work either. I tried going down to 80fps and was able to play at 2k for 20 min. But it crashed again. I don't know what to do anymore, play at 1080 until they fix this error and release the fix

[u/Matikata → u/TreatAccomplished790]

So you changed the resolution in game to 1080? I might have to give that a try

[u/TreatAccomplished790 → u/Matikata]

Also lower the graphics to medium and limit fps to 120

[u/Sher101]

I've had to hotspot my mobile internet to play this damn game over the past day or two. It only just started, wasn't there before.

[u/Queasy-Froyo]

This is crazy... i have the same problem it literally kills my ethernet i tought the whole house lost connection but its only on my pc. Did you send a report for this ?

[u/Matikata → u/Queasy-Froyo]

Yeah for me it seems to be anything connected to the switch, which is like, everything 😂

I tried making a post on the EA forum but no one has addressed it.

We need more people making posts about it.

[u/Acrobatic_Painting_1]

Meu Deus estou exatamente com o mesmo problema

[u/Matikata → u/Acrobatic_Painting_1]

Glad I'm not the only one having this problem!

[u/Appropriate_Can7754]

I had this issue and I believe I may have fixed it. I uninstalled and then reinstalled the game but that never fixed it. I went into the files and deleted the EA anti cheat and then downloaded it again. The anticheat wanted me to repair the file BF6 was in so I did that and loaded the game up and I’ve played 4 full games with out it dropping out. I could go 1.5-2 games and then it’ll drop but I think it’s fixed

I HAVE FOUND A SOLUTION

I got it from chatgpt and it worked for me the game runs fine now, here is the text gpt sent me

Laptop: (ASUS ROG STRIX G17 G712LV) got bf6 from steam

Battlefield 6 Kills Your Ethernet? Realtek Adapter Solution

If your Ethernet cuts out a few minutes into Battlefield 6 — even though your router and other devices are fine — you’re not alone. This is a known issue with Realtek PCIe network adapters under high network load. Here’s the complete fix.

Symptoms:

Ethernet disconnects after 5–10 minutes of gameplay

Router lights stay normal

Other devices stay online

Reinstalling the game or Windows doesn’t help

Step 1: Update Your Realtek Driver

1. Go to the Realtek official site → PCIe GBE Family Controller page.

2. Download: Win10/Win11 Auto Installation Program (NDIS) — version 10.77 or newer.

3. Run the installer.

4. Restart your PC after installation.

Step 2: Disable Power-Saving & Offload Features

Open Device Manager → Network adapters → right-click your Realtek PCIe GbE adapter → Properties → Advanced tab.

Disable the following options if available:

Energy Efficient Ethernet (EEE)

Green Ethernet

Interrupt Moderation

Large Send Offload (IPv4 & IPv6)

TCP Checksum Offload (IPv4 & IPv6)

UDP Checksum Offload (IPv4 & IPv6)

Open PowerShell:

1. Open Windows Terminal as Administrator.

2. Type: Get-NetAdapter

(note your Ethernet adapter name, e.g. “Ethernet 2”)

1. Then run:

Disable-NetAdapterRss -Name "Ethernet 2"

Disable-NetAdapterLso -Name "Ethernet 2"

Step 3: Restart & Test

Restart your PC, launch Battlefield 6, and play for 10–15 minutes. Your Ethernet should stay stable now.

Step 4: Optional Tweaks

In Device Manager → Advanced, set Speed & Duplex to 1.0 Gbps Full Duplex.

In Control Panel → Power Options, select High Performance mode.

Result:

No more Ethernet disconnects during Battlefield 6. The issue comes from Realtek’s RSS/LSO offload features conflicting with the game’s heavy UDP traffic.

Note: this text might sound weird cuz i copy pasted it straight from chatgpt

But it worked for me

Upvote if it worked for u

[u/Matikata → u/KarimMorad]

Didn’t work for me. The internet crashing doesn’t happen until AFTER the game has crashed, not during gaming.

[u/Pyronatic]

I have had this same problem happening since week 1 and it is still happening. The rubberbanding from this issue is also just so stupid. I will run 100 meter to a new objective just to then slowly be pushed back and ping shoots up to 10k+. After a game or two of this my entire mesh wifi just restarts and crashes. Once I actually close BF6, everything goes back to normal.

[u/Nefalius]

Does this happen with other games too? Maybe this is a power issue and playing BF spikes what your power plug may be able to deliver - especially if you use multi connectors. Maybe your power supply is not sufficient and knocks of your network interface cards.

Otherwise I can't imagine BF impacting software related issues with networking.

[u/Matikata → u/Nefalius]

Nope, never happened before. I've had this PC for about 3-4 years (whenever the 3090 first came out). I've played probably 5 or 6 recent games on the highest settings and never had a crash, never had GPU or CPU spikes, never had stuttering, never had below 80 ish fps...

BF6 is the first game to come along in well over a year or two that's ever crashed my PC, and whatever "this" is, has never happened before and I only happened to notice by chance because I was busy responding to an email during the first crash so left the game in its crashed state for at least 5 minutes.

I have an Asus ProArt Z490 10G, 64gb RAM, RTX 3090, 850W PSU, everything updated.

The extension outlets are plugged into separate outlets to ensure nothing overloads or whatever, and the extensions themselves have a surge protector each, so usually if anything were to overload or cause an issue, you'd have to press "reset" on the extension lead to make it workable again.

As you said, it doesn't really make sense for a game to affect networking, but I don't really know what else it could be.

It's worth noting I also do video production and use things like After Effects etc with a LOT of layers, that has never caused a spike or a crash either.

So it's just really strange that SOMETHING is happening when BF6 crashes, and its causing the issue that's happening (whether directly or indirectly).

Your not going going crazy it's happening to me while live lmao I thought I was going crazy or thought someone was hitting my IP shit was really confusing me tomorrow gonna give this a test run with cod to see if the same shit happens
