Bitrate is reducing from 6000kbps to (700kbps, 0kbps 1700kbps, 0) on a stable broadband connection

I've been thinking outside the box with this.

Option 1.
Jailbreak my iPhone, so that it looks like a 5G wifi repeater, connect the stream that way (it'll perform at the upload speed we need)

Option 2.
NDI the Windows Laptop to connect to the Macbook. The Windows laptop does all the hard encoding work, the Mac just receives and sends (since Windows does a better job with the specs of kit I have)

Option 3.
Discovering today that my Macbook can actually now use it's AMD GPU via H264 Hardware Encoder - I've spent all day testing the limitations of this and if I basically lose a camera, I can do a good stream at 720p / 60fps.

Hey guys

I've had two great streams on a Windows Laptop with an NVENC encoder. Its just Webcam work not gaming.

Once I updated Windows 10 and updated some network tweaks recommended on Youtube, my KBPS has gone down from 6,000 to a very low fluctuating number i.e. within 10 seconds I will get readings like this with Red and Amber Lights (ethernet or Wifi)

850 kbps
1123 kbps
1701 kbps
0 kbps
850 kbps
0 kbps
1734 kbps
0 kbps

I'm convinced it is because of something I've done, but when I have reverted the settings I personally changed (using TCP optimiser) that didn't work. I changed the DNS server to a setting supposedly good for gamers, which I changed back to "Obtain DNS Server automatically" in case it was this. No difference.

The Macbook pro sat next to this machine on the same internet conncetion can still get 6,000kbps on Ethernet or WIFI so I've eventually realised it wasn't the internet.

Unforuntately at the same time as editing the network settings, this laptop received a signficant windows 10 update. This laptop is a 2012 Lenovo Thinkpad with an Nvidia NVENC encoder that I bought for the NVENC and I'm actually beginning to think its the Windows update - i *seriously think* I have reversed the handful of settings I had changed. Smart Restore didn't do a backup before this either and I had forgotten it existed.

Do you know a way whereby I can "download some basic settings" or Default things I cannot see back to how they would have been a few years ago as what I'm trying seems to keep a setting lingering somewhere?

A magic network settings wand or something I'm not trying?

I have very similar behavior to this, no idea what's causing it. some streams it will be fine, others it will not be and it looks like this. I've read this entire thread hoping for a solution but none here it seems. did you ever find a solution

thread from the long past...
not sure we ever heard back on a very old Win10 PC and exact data transfer rates... My personal suspicion was either networking (including cable) or Operating System (driver and/or security software)... though without an understanding of PC's hardware resource consumption, it isn't possible to know if PC simply overloaded, or what inter-play caused bandwidth issue.

First,
- recognize speedtest results are optimistic, dropping low results, but it is exactly those lows the define stable streaming bandwidth
- check/monitor LAN usage, and WAN usage to ensure no conflicting traffic. Don't know wow to do this? figure it out. You'll only be swatting in the blind if you don't
- can you do higher transfer rate of other traffic to a different destination (ex file transfer to OneDrive, Google Drive, etc upload)? if yes, then that indicates PC OS and Firewall, Ethernet cable, switch/router, and WAN/ISP connection working [at that moment in time]. Beware any wireless connections (ex. cellular, WiFi)... For example, I can file transfer to OneDrive at over 100mb/s on a fiber optic WAN link, ... you must make sure your target can handle transfers at the rate you are targeting
- If a WAN file transfer works at around expected upload rate, but streaming doesn't, then make sure you don't have security software (or something on router) interfering (don't assume... figure it out/know)... and beware any 'easy' button suggestions.. .they are usually wrong
- Also, try OBS Studio in portable mode.. no plugins at all. test... if that is okay... then time for basic Scientific method/troubleshooting with a real narrow range of things to look at

Follow the steps in the link below to upload a log, then use Analyzer link in sig. If still having issues post link to a new log.

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...
