WiFi breaks while uploading

Hello everyone,

I'm having a persistent issue with my Dell laptop's WiFi, and I hope someone here can help.

Whenever I start uploading a video to YouTube, my WiFi connection drops, and the internet connection icon switches to a globe, indicating no internet access. Despite this, I'm still able to log in to my router, so the connection to the router itself seems fine.

To resolve the issue, I have to restart both the laptop and the router, which is quite inconvenient.

Here’s what I’ve tried so far:

1. Updated WiFi Drivers: Installed the latest drivers from Dell's official website. After this, the internet connection icon shows the connection as established, but the issue with disconnections during uploads persists.

2. Tested Other Devices: I checked the router with other devices, and they all maintain strong and stable connections during uploads, which suggests the issue is isolated to my laptop.

3. Connected to a Different Router: I tried connecting my laptop to a different router, but the problem continued, indicating it's likely a problem with the laptop itself.

4. Checked with Other Services: Interestingly, the issue only occurs when uploading to Google services. I’ve tried uploading to OneDrive (both via the app and web browser), and it works perfectly without any connection drops. However, uploading to Google Drive causes the same disconnection as YouTube.

The issue similar to this was reported few years back with Inspiron 9300 (‎Wi-fi disconnects when uploading large files on a network drive | DELL Technologies) My is Latitude 3540 with Realtek RTL8852BE network card. Any advice would be greatly appreciated!

Thanks in advance!
