Ideapad 500S - Wifi connection stops working when HDMI is plugged in

2017-01-09, 16:59 PM

Hi everyone,

 

the wifi connection on my Ideapad 500S-14ISK stops working when I connect to any external monitor via HDMI. I've had this problem eversince I've gotten this laptop.

The wifi works fine, only when a monitor (either the TV or my external monitor, using different cords) is plugged in I lose my internet connection, even though it still shows full wifi connection. It works very briefly if I disconnect the wifi and connect again. Starting the computer while the monitor is already plugged in does not help. All drivers are up to date.

 

Thanks in advance for all replies, I appreciate it.

Hi Jakob96,

 

Have you already tried downloading the latest driver for the video card from Intel.com, also what wifi card do you have on the system. If both device are made by Intel please update both drivers.

 

Hope to hear from you soon.

 

Cheers,

We have the same issue in our company on Lenovo T470p (we have few of them) - when we plug in monitor through HDMI port the internet is slowing down or shutting down. All laptops with this issue have the same wifi card:

 

03:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)
Subsystem: Intel Corporation Dual Band Wireless-AC 8265
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

 

System: Ubuntu 18.04.2 LTS or Windows 10

Hot spots: Ubiquiti UniFi AP, AC Long Range and Ubiquiti UniFi AP, AC PRO
