OBS software disables Wi-Fi when running

[JRHorse]

I am encountering issues with OBS since attempting to update my windows OS to 24H2, where my Wi-Fi connection to the computer is completely disabled whenever the OBS software runs, and comes back when the OBS software is closed. I can use my Wi-Fi connection on the computer as normal, except when the OBS software is running.

I am continuing to have issues after doing the following, in order:
- Roll back Windows to 23H2 and run the OBS software
- Uninstall SE Live and run the OBS software
- Uninstall OBS, reboot, reinstall OBS and run the OBS software
- Update Wi-Fi to latest driver

I use the on-board Wi-Fi that comes with my motherboard (MSI Mag B650 Tomahawk).

Thank you in advance for any assistance.

Try unplugging your USB capture card as some USB ports generate EMI that can cause issues with Wi-Fi. If that fixes it, try a port far away from the Wi-Fi antennas.

Hi, sorry for the delayed reply. After doing a FULL uninstall of OBS, including removing all scenes and scripts, I have no problems while OBS is running. My guess is that by some weird chance, one of the scripts or plugins I used to run went bad either before or after attempting to update Windows. Sadly, this is at the expense of building all of my scenes over again from scratch, but building a new scene set has (so far) resulted in no problems.

I do not have a USB capture card.

I do not have a USB capture card.

there is log entries that says that you had USB device "Game Capture HD60 S" connected:

20:54:57.352: [DShow Device: 'Elgato Capture'] settings updated:
20:54:57.352:     video device: Game Capture HD60 S
20:54:57.352:     video path: \\?\usb#vid_0fd9&pid_0076...

likely, this device was mentioned in the previous post. This device was present in the scenes: 'XAR Logo with Links SLOT' (current scene), 'Game Stream', 'Game Stream SLOT', 'XAR BRB SLOT', 'Game Stream MSFS', 'Gartic Game' and 'Flight Simulator Full'.

Timeouts in the connection:

20:55:05.815: OAuth::GetTokenInternal: Failed to get token from remote: Resolving timed out after 5001 milliseconds
20:55:20.512: AutoUpdateThread::run: Failed to fetch branches file: Failed to connect to obsproject.com port 443 after 21005 ms: Could not connect to server
20:55:20.577: WhatsNewInfoThread::run: Failed to fetch whatsnew file: Failed to connect to obsproject.com port 443 after 21010 ms: Could not connect to server

says that the network adapter was working (not in OFF state). Thus, there is assumption that cause is EMI (electromagnetic interference) from equipment that consumes a lot of power or located close to the Wi-Fi chip. Video card (mostly at half load) and capture card are first candidates. OBS users usually prefer wired connections to the router.

Updating with new issues... after a few streams run with my new scenes and what not, tonight while streaming the OBS software killed my wi-fi about 40 minutes in. Thereafter, it's returning to the same issue of my wi-fi going down when OBS runs, and coming back when OBS closes.
I disabled hardware accelerated GPU scheduling, which was recommended by the Log Analyzer, to no avail.
Log files attached, one from before the wifi issues and one from after.

This is network issues. Hardware issues. OBS has no control over it. Your hardware responded that there was "send error" (literally, hardware fails to send data).
The first action you can take is to connect your PC by wire (patch cord at least category 5) to your router (network).

I do not see how it is a network issue when running OBS causes my wifi to disconnect, and closing OBS restores it? The network issues only happen when the OBS software is open. If I run any other software on my PC, my wifi is not affected.

Quick update: fully uninstalling my BitDefender software appears to have cleared up the issues with OBS for the time being. I guess I'll stick to plain old Windows Defender for now?

 

[Suslik V]

The mentioned "send error" originates from hardware. Why not to try patch cord?

Most likely you did NOT need to uninstall BitDefender (I'm not advocating either way), but rather adjusting the right settings in that app (just beware typical ID10T/PEBKAC end-user error of adjusting something to get it to work, and opening up yourself to a compromise in the process... understand the implications of the changes you make).

As for not seeing how network issue... that indicates a basic lack of understanding of the various hardware and operating system interactions, and how your system reacts to being 'overloaded' (which per your later note can also be some other s/w (with OS filter driver in network path, in this case) causing a bottleneck).

Also, most likely no other software is pushing your PC the way real-time video encoding combined with whatever else you are doing, while sending (vs receiving) data. And WiFi has never been, and most likely never will be, appropriate for jitter and latency sensitive traffic like livestreaming (literally not designed for that... works ok in certain limited circumstances, and is VERY easy to 'break'. Certain web conferencing s/w works more reliably due to using much lower bitrates and proprietary (patented) techniques not appropriate in free, open-source world).
I say this as WiFi is great, right up until it isn't. If you want reliable/stable, jitter and latency consistent network traffic, don't use WiFi. period.
If you do use WiFi, and especially if you don't have real-time WiFi monitoring in place (I do, most don't), don't be surprised when network traffic over WiFi starts acting up... it is to be expected.

Thanks for the information, unfortunately I'm in a situation where a wired connection is not possible (at least for the time being)

I have now unloaded all my scene files (new profile and scene collections, with scenes and sources blank), and OBS software opens with no wifi disconnects. At this point I'll have to check my sources to see if one of them is the culprit?

 

[JRHorse]

It appears that a script on my computer that I had loaded into OBS, the NVIDIA Background Removal plugin (which I had downloaded a while ago from the NVIDIA Broadcast SDK page), might be the culprit.
Removing my webcam as a source in OBS cleared up the Wi-Fi problem. Adding the camera back, again, the Wi-Fi is fine. But it's when I add that plugin as a video effect that my Wi-Fi goes bonkers.
Go figure...

 

[Lawrence_SoCal]

That sounds like a CPU overload situation (from what I recall reading about that plugin from a while ago). Are you dong real-time hardware resource utilization monitoring? if not, you are doing the equivalent of driving blindfolded
