![]() ![]() ![]() This variation does not try to match on the interface name, but rather looks in /sys/class/net for information on the device. (I don't have the reputation to comment.) This one works for Fedora as well, where network interfaces can now have names like wlan0, wlp6s0, em1 and enp0s20u2u1). This is an improvement on Cyril Fessl's previous answer. Tested with Ubuntu Desktop 10.10, and should work with earlier versions or other distributions using NetworkManager and dbus. You could also use 'ifconfig wlan0 down' or 'ifconfig wlan0 up' instead of the dbus-send line, but this should be more user-friendly and interfere less with Ubuntu's system utilities. This enables/disables wireless in the NetworkManager that can usually be found as an system indicator in the Gnome panel. Make sure these scripts are executable with 'chmod +x'ĭbus-send -system -type=method_call -dest= /org/freedesktop/NetworkManager .Set string: string:WirelessEnabled variant:boolean:falseĭbus-send -system -type=method_call -dest= /org/freedesktop/NetworkManager .Set string: string:WirelessEnabled variant:boolean:true These scripts could easily be adapted - by boolean logic - to a situation in which you have two or more cabled network interfaces. (Only an issue if you have multiple wlan interfaces and only want to disable specific ones) Note that this disabled wireless entirely, not just wlan0. Check this with 'ifconfig' if you're not sure. While LAN does trump WiFi the NM (Network Manager) will find what you seek should you be on different networks simultaneously and are working both online (WiFi) and with a local host (LAN) or V/V for example.Ĭreate two simple 'scripts', the name of the script is not important (I simply use wlan) and I assume there is only one cabled network interface, and is thus called 'eth0'. ![]() Simply unplugging your Ethernet cable will seamlessly transfer the connection to WiFi and you can pick up and move about without any fuss. LAN trumps WiFi automatically, there is no need to disable WiFi.Naturally you could also disable/enable Wireless by right clicking the network icon and then left clicking on the "Enable Wireless' selection, effectively bringing down or up the Wireless interface as indicated by the presence or absence of the check mark. This will leave the Wireless network operational for on-the-fly manual connections and disconnections available by left clicking the network icon, without the NM trying to Automatically connect you all the time. Repeat for each connection in the list.Double click the first connection in your list and Uncheck the 'Connect automatically' box.Note that the up/down icon will appear when both LAN & WiFi or only LAN are connected and the WiFi funnel appears when connected via WiFi ONLY. (The indicator will be one of two icons either the up/down arrows (LAN) or the traditional WiFi Funnel. Right click on the network system indicator in the gnome panel up by your clock. I'll try again with the ports at my friend's apartment that I know work.Quite simply for the gnome GUI approach. ![]() The network icon still says "cable unplugged." Is there something with the IP or MAC address that I need to change?Īlso: I know that the hardware can handle wifi-the Mac OS uses wifi without any problemsĮDIT: the Ethernet cable doesn't seem to be recognized by other computers either, so I think the Ethernet ports in my apartment simply aren't connected to the router anymore. The installation seemed to work just fine, but 1) there's no option to connect to wifi for some reason, and 2) the new Ethernet cable I just bought this afternoon doesn't seem to be doing its job. I recently installed Linux Mint 18.3 Cinnamon on an old iMac which still has the Mac OS on it (partitioned with only 50 GB of the HD). Idk why they're off by default, but problem is solved now) (The issue was actually that I had to put in a service request for the IT peeps to turn on the Ethernet ports. ![]()
