What you can do is to use nmcli dev list iface wlan0 to view information for your wireless interface, same as listed in nm-tool although in somewhat different format. To view info for alll interfaces, use nmcli dev list . There is a lot of material , so you can pipe it all into less like so : nmcli dev list | less And here is a little one-liner I ...

I am not sure I understand everything you say. But NetworkManager saves into the keyring your openVPN password unless you tick/check the "Allow all users to use this connection" in the VPN configuration in NetworkManager applet. So if you checked that checkbox, the password is saved in /etc/NetworkManager/system-connections/YourOpenVPNConnectionHere You ...

If you have networking and can ping by IP address or hosts listed in your /etc/hosts file, but can't browse to websites, it sounds like improper DNS resolution. Some quick tests: $ ls -l /etc/resolv.conf lrwxrwxrwx 1 root root 29 Apr 23 09:44 /etc/resolv.conf -> ../run/resolvconf/resolv.conf $ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for ...

You can change the timeout of nm-online to something like 10: Edit /lib/systemd/system/NetworkManager-wait-online.service as root or using sudo. Look for the lines: [Service] Type=oneshot ExecStart=/usr/bin/nm-online -s -q --timeout=30 Change 30 to whatever you like. 10 worked well for me. But beware this may break services that depend on it.

Had the same problem in Ubuntu Mate 15.04. "sudo pppoeconf" in terminal got a working DSL connection. It asks several configuration questions, then it is possible to connect with "pon dsl-provider" and disconnect with "poff dsl-provider". Added two buttons with these commands on panel and removed network-manager from startup apps for now.

I accepted 2707974's answer (great name) but here for anyone wanting to automate this stuff with a one-liner to change from 1.2.3.4 to 5.6.7.8 sudo find /etc/NetworkManager/system-connections/ -type f -name "Wired*" \ | while read c ; do sudo sed -i 's/1\.2\.3\.4/5.6.7.8/g' "$c" ; done ; \ sudo service network-manager restart Of course this assumes ...

The problem that I am seeing is that with the 15.04 upgrade and all of these fixes, I can get the laptop to connect to an NG-mixed station but not to an N-only station. All of my wireless AP's were set to N-only, and I have had to revert them to NG-mixed to get the connection.

Found an answer: sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/backup-iwlwifi-3160-12.ucode sudo mv /lib/firmware/iwlwifi-3160-10.ucode /lib/firmware/backup-iwlwifi-3160-10.ucode Reboot. Seems to be an issue with the firmware. After reboot I was able to connect again, so for me it is working.

Well, you only installed one of a few things you need. Follow PIA's instructions for Ubuntu 12.04 to the later: Install these packages. sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome Add a new OpenVPN connection.

I ran into this too because regular Ubuntu works differently than Kubuntu. Kubuntu has the VPN settings in the "connection editor", which is not in the regular network settings. If you click on the current network connection (ie WiFi) in the area at the lower right corner of the desktop, then click the "wrench" icon at the top right of the popup, you will ...

Open a terminal and type: sudo pppoeconf Enter your Ubuntu password. If you don't know how to answer the questions it asks you, answer with yes. Then it will ask you the DSL username and DSL password.

From man NetworkManager.conf: keyfile plugin is the generic plugin that supports all the connection types and capabilities that NetworkManager has.

Okay, I've got DNS working again. Since it appeared that DNS was being configured right I started wondering about iptables. I flushed the current iptables rules and DNS immediately began working. iptables -F However, the problem returns after rebooting. Now it appears to be a matter of making permanent edits to my iptables. Apparently I had installed lokkit ...

Add your desired dns server to /etc/dhcp/dhclient.conf on the line saying supersede domain-nameserver. Separate by comas your dns addresses. Save the file and restart the network manager

Do you have any particular reason to circumvent the use of dnsmasq? otherwise, I'd suggest reverting your changes to NetworkManager.conf and then reconfiguring the resolvconf package. After that, you should be able to add your chosen DNS servers via the 'IPv4 Settings' tab of the nm-applet GUI, after changing the mode from 'Automatic (DHCP)' to 'Automatic ...

It might just be a typo if you copied by hand but the line in /etc/NetworkManager/NetworkManager.conf should be dns=dnsmasq not dns=dnqsmasq that you have reported. Your /etc/resolv.conf file is missing a nameserver line echo "nameserver 127.0.1.1" | sudo tee -a /etc/resolv.conf Then reboot

The following command resolved the problem echo -e "nameserver 8.8.8.8\nnameserver 8.8.4.4" | sudo tee /etc/resolv.conf Then restart network-manager with the following command sudo service network-manager restart Then I restarted the computer for it to work.

There is no concept about broadcasting a folder!! What you can do instead is making a directory shared to others without permissions, so that every one in your network can see, read and write in it. Install Samba sudo apt-get update sudo apt-get install samba Set a password for your user in Samba sudo smbpasswd -a <user_name> Create a directory ...

You should add the route to PC#3 (the one with IP address 192.168.2.101): route add -net 10.0.0.0/13 gw 192.168.2.21 Or you can edit your network connection to automatically include a static route when the connection is established (IPv4 Settings tab -> Routes button):

Network Manager stores system-wide connection information in the /etc/NetworkManager/system-connections/ directory, with one file for each named connection. For eth0 it may have a default name such as Wired connection 1.

This will not recover your gnome-connection-manager, but allow you to manage your connections through the terminal: You can use nmcli instead of your normal connection manager.

Edit: This seemed to increase the time it takes before it disconnects, but it will still eventually disconnect. :-( When I run: sudo ifconfig wlan0 down sudo rmmod ath5k sudo modprobe ath5k nohwcrypt=1 sudo ifconfig wlan0 up The wifi will not disconnect until I reboot. To make this permanent by adding options ath5k nohwcrypt=1 to ...

Your Firewall is configured to block all ICMP packets, as a result you can not send ICMP echo request packets to external networks. To resolve this issue you need to contact the network administrator and request him to disable this firewall rule.

See http://askubuntu.com/a/63163/267945 - much better solution: If you want to override or append to the name servers suggested by the DHCP server, you can configure this in /etc/dhcp/dhclient.conf, eg: interface "eth0" { prepend domain-name-servers 10.0.0.2; }

With network-manager, you can enforce a specific access point BSSID via the connection editor Edit... then select the Wifi tab and enter the BSSID:. Obviously this solution requires that your users don't have sufficient privileges to subsequently modify network-manager wireless settings.

iwlwifi driver has some problems with 802.11n protocol and some Intel wireless cards. The solution is to disable the N protocol and go with probably slower but more reliable variants of the 802.11 protocol. You can achieve this by executing: sudo sh -c 'echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf' And reboot. Please let ...
