[10:46] <dvora> i have internet problems- i have lubuntu 14.04, and in the last few weeks every few minutes/ hours (randomly!) my nm-applet stops seeing any networks. when i disable and then enable i goes back to working perfectly, for some time... what can couse that?
[10:53] <phillw> dvora: network issues are a nightmare... head over to http://ubuntuforums.org/forumdisplay.php?f=336 and read the 2nd sticky. Feel free to ask on there as all the *buntu family share the same system for networking.
[11:18] <testdr> dvora: nm-applet dropout for wireless or cable-connected internet?
[11:19] <dvora> testdr: wireless
[11:21] <testdr> dvora: if it was OK for some time(weeks/month) before - there can be changes in the signal-strength. Check if other wlan-nets appear, if your wlan is not the only one.
[11:22] <testdr> dvora: and for the time of the network-dropouts, check /var/log/syslog* (some older are compressed) to get some information when it happens and what error/info-messages are there
[11:25] <testdr> dvora: and last you have to check, that it is not any hardware-failure. That might happen if hardware "gets older". Signal-strength may be lost and so on and you can check this if you have other hardware (with same software), that has not such dropouts.
[11:31] <dvora> testdr: tanx.it's not the strangth of the connection. it stops seeing all network available (including all the nets of my neighbors)
[11:40] <testdr> dvora: if it is a laptop, then it could be some hardware-fault and you can check this if you get a wlan-usb-stick and disable the built-in-wlan. If it is a desktop-pc with wlan-usb-stick, same: you can check with another one.  Last point could be someone is trying to intrude your system and breaks it - but i would first check hardware.
[11:42] <testdr> dvora: did forget - you can run (in a terminal) a constant ping to your internet-hub/router of your local net to make shure it does not happen from some power-saving-settings. If power-saving enabled the network should be re-connected after power-saving - but if not, this is like the network will be dead, because the hardware was not re-initialized after power-saving-level
[11:44] <testdr> dvora: if you still have the ubuntu-live-iso, then you should boot this and verify that its not some special user-settings (power-saving) that does not re-enable the hardware. Just run the ubuntu-live-system for some hours (browsing the internet and so on).
[11:46] <dvora> testdr: it's a laptop. i don't have wlan-usb-stick, i'll try to get one and check it. i don't think it's a power saving think- because it happens sometimes while i use the computer
[11:49] <testdr> dvora: then test it with a constant ping running in an terminal, like "ping -i 1 192.168.0.1"  -- you have to set the ip of your home-router. That will send pakets every second and you see the output in the terminal and you will see when it will fail.
[11:51] <testdr> dvora: if - with this constant 1second ping - the connection will not fail, then its some other reason
[11:57] <dvora> testdr: ok, so i try that. so to be sure, if the connection still fails, what would that mean? and what will it mean if it doesn't..?
[12:00] <testdr> dvora: it could be your wlan-router, that is dropping the signal-strength - maybe if there is inactivity - did you have wlan-dropout during some longer downloads (like during ubuntu-updates or download of iso-live-images)?
[12:04] <dvora> testdr: i haven't tried. but it can happen when i download torrent files for example... it can happes even while i surf
[12:05] <dvora> testdr: now i'm downloading ubuntu updates and so far so good. but it's really random i think
[12:11] <testdr> dvora: check the messages in /var/log/syslog for those droppouts. No messages? Btw. if you have cable available and not to far from your router, this is a way to get a working connection if the reason could not be found.
[12:17] <dvora> testdr:  i don't have a cable. maybe i should buy one... there are massages in the syslog, just not sure what they mean.... i can send you the syslog
[12:20] <testdr> dvora: use the pastebin for such things and post the link to the text there
[12:20] <testdr> dvora: lookup pastes: http://paste.ubuntu.com
[12:27] <dvora> testdr: at 12:59 i had a dropout, and at 13:15 i saw that and disabled-enabled the networkmanager to fix that. http://paste.ubuntu.com/8342491/
[12:36] <testdr> dvora: did you read: http://askubuntu.com/questions/465848/frequent-deauthentication-from-wifi-reason-6-in-ubuntu-14-04
[12:43] <testdr> dvora: only to make shure, that wlan "tishuwantsplay" is yours?
[12:44] <testdr> dvora: you got last question?
[12:46] <dvora> testdr: i just had this drop-out. i saw the link you sent, i'll try that
[12:46] <testdr> dvora: last question was: Is this wlan "tishuwansplay" yours?
[12:49] <dvora> testdr: thats the name of my network
[12:50] <testdr> dvora: ok - then you can lookup the mac-address and where the disconnect happens - its seems at the point where the scurity-handshake is done again with your wlan-router and this handshake fails
[12:53] <testdr> dvora: this is from your pasted output of syslog - and it may be that this handshake will work for some time and suddenly could not be established again - could be hardware or bad signal-strength (some other hardware around may jam your connection) - it could help to change the wlan-encryption, but you should only try this, after you got a cable to connect to your router, because if you misconfigure your wlan-settings, this is the only way to reach your rout
[13:02]  * RedDeath Back
[13:02] <dvora> testdr: so i'll get a cable, and see if that helps

[22:00] <Gassho> how do i see how much juice my laptop has left?
[22:26] <ianorlin> Gasshoo which version of Lubuntu do oyu not see a battery icon?
