What you describe seems like dhcp lease issue. When you connect to the router, dhcp gives you ip for some particular amount of time ( that's what's called lease ), and then that gets renewed. For example, here's what I have in my syslog: $ grep 'renew' /var/log/syslog Jun 30 20:38:01 anaconda dhclient: bound to 192.168.43.209 -- renewal in 1342 seconds. ...

First, identify the driver for your network device with the command: lshw -C network Look for driver=. Next, check the log for clues as to why the device disconnects. I suggest you look at both the driver and what Network Manager is doing: cat /var/log/syslog | grep -e some_driver -e etwork | tail -n 20 Ideally, run this just as the internet ...

If you know the websites that you want to access using wlan0, then you can add corresponding rules to your iptables. Alternatively you can configure just one of the two browsers to use the proxy server.

Since this question still hasn't been answered I figured I might answer it myself with what I believe is the best solution. I've run unto this problem before in the past few years so it's safe to assume that it's not something that's going to be fixed soon. Even though I was able to get my network card working the previous times, it always cost me a day or ...

I had the same symptoms with wireless connection after upgrading a desktop computer to Kubuntu 15.04. After lots of research I found something that suggested that combined WPA/WPA2 mode on the router that generated the wireless access point could be problematic. I reset the parameters in the router to force it use WPA. As suggested, I used AES (NOT TKIP). ...

To try to solve my issue I removed the 802.1x security in the connection settings. When I then added it back I was able to save the password in the settings. That got it working.

These NetworkManager errors and UFW blocking are related to router solicitation messages. ICMPv6 TYPE=133 are your host originating requests for IPv6 configuration. If you use IPv6, add a rule in (g)ufw: Policy: Allow, Direction: Out, To: ff02::2 and the messages won't appear any more. If you don't use IPv6, disable it by following the answer to this ...

Install macchanger and have it run every time the network connects by using a udev rule.

The Arch Wiki lists several Display Managers, of which three lightweight Display Managers are XDM (153 total dependencies1), LXDM (172 total dependencies1) and SLiM (121 total dependencies1). Personally I'd liked the themes available for LXDM, and the SLiM Arch Wiki page says the project is abandoned (it worked well, though). It also lists a couple of ...

Network Manager does not manage interfaces that are mentioned in /etc/network/interfaces. That sometimes confuse people. If you add all interfaces there, NM indicator will not appear at all.

This thread came up tops in search but was not marked SOLVED so I'll post what worked for me. Most driver and configuration bugs have been worked out, hence methods to remove or override stubborn hardware locks don't work and lead only to frustration. The first step should be to locate the wifi/wlan switch and toggle it. It may be a function key, slider ...

Okay so after some more digging and lot's of experimentation it turns out I have to in fact lower the MTU of wlan0, rather than increase it. The reason, as far as I understood and please correct if I'm wrong, is that probably one of routers or a switch on the way is having a lower MTU as well, thus although it sends the packets correctly, my guess is that ...

This worked for me. It sets up the hotspot connection using the Kde network-manager connection editor. I'm on Ubuntu 14.04(.2) 64 bit.

Drivers in linux kernel for this adapter are not very good. Download THIS FILE Also linux-firmware should be updated for 12.04. Copy it to your home folder and run sudo dpkg -i rtlwifi-new-dkms_0.5_all.deb If there are no errors, reboot.

This could be due to excess devices being in your /etc/network/interfaces configuration file, apparently Ubuntu / NetworkManager sees any non loopback device and decides that it does not need to start (properly).

I recently re-installed my laptop (which has loopback, WIFI and wired network connections) from scratch and I found that it has "NetworkManager is not running" displayed when I click the NetworkManager applet, which is apparently not that strange.

Generally the primary server is used first. That's why it is called the primary server. So in your case '.57' is used which is what you want. Only if it does not respond the secondary server is contacted. If that one does not respond too the teriary server is contacted. If none of them responds you'll get an error about resolving. And there's a 100% ...

Try running the command: :~$ locate dpkg which should be found in /usr/bin/ as /usr/bin/dpkg.

I believe you are having a problem with /usr/bin/nm-applet part of the network-manager-gnome package. If so you can obtain that package for your architecture from here.

Each wireless adapter has a unique solution. Sometimes groups of adapter have similar ones. Dozens of different adapters. Also there laptop model specific solutions.
