To me, this looks like packet loss / a connection issue. It's possible for it to happen to only you, even if both you and your boyfriend are on the same network.
I recommend troubleshooting with ChatGPT. Copy-pasting from my own prompt:
- Network adapter / driver issues (very common)
Your PC’s Ethernet controller might:
Have outdated or buggy drivers
Be misconfigured (speed/duplex mismatch, power saving, etc.)
👉 This alone can cause:
Packet loss
Stuttering
Failed round transitions
Meanwhile, your boyfriend’s PC = different adapter → no issue
- Bad Ethernet cable or port
Even wired connections can have problems:
Slightly damaged cable
Loose connection
Faulty router port
👉 Result: intermittent packet loss (not total disconnect)
- Background network usage on your PC
Only your machine might be:
Uploading/downloading something
Running cloud sync (OneDrive, Google Drive)
Using bandwidth-heavy apps
👉 This causes:
Packet drops under load
Especially noticeable during game transitions
4. Firewall / antivirus interference
Some security software:
Inspects packets in real time
Can delay or drop them
👉 This can cause:
Exactly what you described (stutter + failed loading online)
5. Network buffer / interrupt issues
More technical, but real:
Your NIC (network card) might be struggling with packet handling
Especially under burst traffic (like between rounds)
🔍 Quick ways to confirm packet loss
✅ Test 1: Ping test
Open Command Prompt and run:
ping -t google.com
Let it run while playing.
Look for:
Request timed out
Or spikes (e.g., jumping from 20ms → 200+ ms)
✅ Test 2: Compare with your boyfriend’s PC
Have both of you run the same ping test at the same time.
If:
Yours shows drops/spikes
His doesn’t
👉 That confirms it’s your PC specifically
🛠️ What I’d try first (high impact fixes)
- Swap Ethernet cable + port
This is simple but very high success rate
Use his cable on your PC
Plug into the same router port he uses
2. Reinstall network drivers
Go to your motherboard manufacturer’s site
Download latest LAN drivers
Install fresh (don’t rely on Windows auto drivers)
3. Disable power saving on network adapter
Go to:
Device Manager → Network Adapter → Properties → Power Management
Uncheck:
👉 “Allow the computer to turn off this device to save power”
4. Disable background apps
Close:
Browsers
Discord streaming
Cloud sync apps
5. Temporarily disable antivirus/firewall
Just to test
If packet loss disappears:
👉 that’s your culprit
🎯 Key takeaway
Same internet ≠ same connection quality
Each PC has its own:
Network hardware
Drivers
Software environment
And any of those can cause packet loss on one machine only.
