 Posted: Tue Oct 11, 2016 9:48 am Post subject: NetworkManager keeps killing my wi-fi when I plug in cable |
 |
|
I am trying to solve this bug https://bugzilla.kernel.org/show_bug.cgi?id=176891 one of devs told me that reason why my wi-fi is getting killed when cable is plugged is not kernel in fact, but rather NetworkManager which has some power saving features or whatever.
Is that true? How can I disable that? I don't want NM to kill my wi-fi when I plug in cable I want both. |

I don't have the same hardware as you, but NetworkManager does not kill Wi-Fi when I connect an Ethernet cable to the laptop; both connections remain active. Therefore I don't think what you are experiencing is an inherent trait of NetworkManager. I don't know if it's of any help, but here are the details of what is installed on my Clevo laptop:

Use net-wireless/rfkill to check which of the kill states change when you plug/unplug the cable. |

Hard block :/ there is no "switch" on my laptop other than fn + PrtScr which does nothing when I press it. Hard block can be only removed by plugging the cable off |

So the network jack seems to hard block the radio when cable is in. Guess you need to modify your hardware ... |

According to the Dell Latitude E5550 / 5550 Owner's Manual, the laptop's BIOS includes the following settings:
| Quote: | Wireless Radio Control
Allows you to enable or disable the feature that automatically switches
from wired or wireless networks without depending on the physical
connection.
• Control WLAN Radio
• Control WWAN Radio
Default Setting: The option is disabled
Wireless Switch
Allows to set the wireless devices that can be controlled
by the wireless switch. The options are:
• WWAN
• GPS (on WWAN Module)
• WLAN/WiGig
• Bluetooth
All the options are enabled by default. |
Looks like you have four possible combinations for Wi-Fi. It would be worth trying them all to see what happens.
