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 ...

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. ...

If you wish to continue with /etc/network/interfaces, wireless will require the addition of the network you intend to connect to and any encryption details.

Go to the Network Settings and find out unintended wifi networks and go for edit-->general-->uncheck the option-- automatically connect to this network when available. I think this should solve it. You can always select the optional wifi from the main menu bar.

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 ...

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 ...

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 ...

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). ...

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% ...
