I have a problem with my ethernet.

I came here with the same issue.

Only when using OBS does my stream start fine and with 30-40 seconds it goes to 0 kbps. If I upload a file to my server it'll stay at 10-12 mbps all day. OBS kills it with 100% frequency. I've been using OBS for nearly a decade, never seen this before.

My ISP has told me they can do nothing as it's not on their end.
Ethernet not wifi. New cables. All drivers and updates are in place. Firewalls, defender turned on/off for testing to no affect. All network options within OBS tried to no affect. Uninstall/resinatll with reboots at every step tried. I currently can not use OBS to stream. Even tried eliminating it being a camera issue, display driver, network driver, audio driver, power saving issue, anything and everything.

Stumped and annoyed.

Anyone with anything left to try (or an answer?)
 
So I seem to have found the problem.

In frustration I changed from 24 fps to 30. It works.
Switched back to 24. Ethernet traffic brought to 0 within 30s
Back to 30, it works...
switched back to 24, ethernet traffic brought to 0 within 30s again.

I always figured while trying to diagnose this changing the frame-rate to a higher value would be stupid. I can re-produce this effect on command now. 24 fps kills my ethernet. 30 I can stream fine.

Mind blown.

When I start the stream it goes directly 0 kb/s I dont know why I have this problem for like 5 months and I cant do my streams also this problem is only on my ethernet cable when I tried without ethernet cable it worked on my laptop also tried with ethernet and I had this problem idk what is it I need HELP!! https://obsproject.com/logs/VKAwsuc7mJsW_yWA

13:30:32.573: Output 'simple_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 1223 (64.2%)
you have a network problem, not an OBS problem

IF same laptop works over Wifi and not Ethernet, then something very wrong with wired Ethernet network. could be other (like security or hardware driver) s/w on laptop, OS NIC settings, the physical Ethernet interface, the cable, the RJ45 interface on switch/router, switch/router settings, etc... nothing to do with OBS
And I'd expect you to (unless odd (/broken) setting specific to port/traffic type of streaming) be able to confirm similar traffic throughput impact using wired Ethernet connection when doing large file transfers or similar upload traffic

No sir.
Network is fine until I hit stream on OBS with 24 fps selected. I'm aware it makes no sense but it is 100% repeatable for me. Same thing happens even when I mobile hot-spot it. My mobile is a different ISP than my home 'net. Any other use of my upload (other than 24fps in obs) is just fine. I get my speeds with no drops.
 
Trevor - not I was NOT responding to your but the original poster. It is rude to hijack a thread like you have, and I will ignore all other posts of yours on this thread. And unless you have something at, or approaching, Sr Network engineering expertise (and your comments indicate you clearly don't), then you are mistaken to think I'm going to put much consideration into your diagnosis of network issues, which the OP has (while your issue doesn't appear in any way related to the network). You aren't even having a similar symptom.... jeesh
 
Interface: Realtek PCIe GbE Family Controller (ethernet, 100 mbps)

Your gigabit network card is only connecting at 100mbps, this usually means a bad cable or outdated router / switch.
