I have 5G internet connection. Speed is always between 200 - 300 Mbps. When I am downloading something and download speed goes above 150 Mbps, WiFi turn off. It doesn't even show available WiFis. Rebooting the system doesn't help. I have to shut down the system and start again. I researched and tried below solutions but unfortunately none worked.
- Restart network manager.
- Disable power management
- Disable 11n
- Uninstalled network-manager and installed WICD network manager
- Reinstalled Ubuntu 16.04
My system:
Lenovo Thinkpad P52.
Wireless Card: Intel Wireless AC 9560<
Anybody faced same issue and have solution? I will really appreciate the help as I am trying to resolve this issue for last 1 month and it's driving me crazy.
Thanks
[Solved]
Updated the kernel to 5.1.3 using Ukuu Kernel Update Utility. It's been 2 days now since laptop is up and running and WiFi is not turned off. Noticed other things as well after updating the kernel. WiFi Signal is always 100% now. Earlier it was always between 80 - 90 percent. Also, boot time has reduced significantly.
