ubuntu 12.04 internet

so iv been testing ubuntu 12.04 on my netbook, and everything seems to be going great. all except one thing. the Internet seems to work fine when on battery power, however if I plug the cable in to charge, the Internet does not work at all. is this a bug, or is this just some small configuration issues I can solve?

 

hi, i dont think you understand what i mean. i am already using ubuntu, however the most recent one that will be coming out is in april and i am having issues using the internet, whilst having the charger plugged in.

 

im using 11.04 at the moment, i have no issues with the internet, i have the power cable plugged in and the internet is fine, however if i use 12.04, the internet will only work with the power cable out. maybe configuration?

 

I think you might have a fruitful time looking through the network-manager and battery monitor configs, and how the applets are assigned to the system tray o wherever. What desktop are you running.. and have you tried others like lxde/xfce etc to see if the problem is common to all?

 

i had the same problem with 11.10 and yes i did use other desktops and the outcome was the same, however i will try with the configurations and hopefully that will sort things out

 

i tried using dconf but i have no idea what i am looking at. iv looked through the power configurations, but nothing relevant there. could you possibly tell me where to look? thanks for the help

 

As I'm running Arch I don't think my system is anywhere near enough to yours to have much of an idea what may be wrong even if I saw it... including the fact that I don't have this problem and so can't duplicate it. It's not just dconf.. it's rc.d and rcS.d and any desktop.conf files.. look for things being loaded twice I would guess. There are a few threads on the network-manager applet being a bit touchy.

Try ask ubuntu or the ubuntu forums, somebody must know..

p.s .. browsers suddenly crashing?.. flashplugin-nonfree update is really broken.. replace with a 10.xxx from adobe archive manually

 

nothing is crashing, no browsers, no plugins nothing, just no internet i guess il have to check ask ubuntu. by the way, what is arch like? any benefits of using it over a debian based distro?

 

Arch is pretty hardcore, but because it's bloat free it's blazing fast on old hardware.... but... you really do need to know what you are doing in case things don't work.

I still think your main problem is caused by running upstream testing version. Chances are a clean install (apt-get remove --purge network-manager battery-monitor) would do the trick, reinstalling them again afterwards. I managd to get 2 network monitor applets to load and had to take the one out of rc.d as network manager #comment it out to see# is handled by desktop startup .. maybe??

Wonder if Mick has any thoughts on this one.

 

Maybe acpid is doing something screwy with the on/off battery events?

 

It is probably also worth adding that since you're playing with a beta version of Ubuntu, you should be reporting the errors to the Ubuntu devs so that they can fix it for the release version.

I personally find Arch fun, I actually enjoy having to put all the pieces together myself and getting myself out of trouble when something goes wrong (happening quite a bit now that I've got an ATI graphics card...). It is a steep learning curve, if you do want to have a go at it, I'd recommend trying it on a computer you don't need to rely on and can spend a week or two experimenting - you'll almost certainly find yourself formatting and reinstalling! But you WILL learn a lot about what actually makes up the operating system as a whole.

 

My arch lappy has an old lump of ati hardware.. it refuses to work with either of the "proper" drivers, but it's sweet with the vesa chunk so I'm happy.. except AGAIN with flash which latest update caused instant browser exits stage left (running even) .. at least with arch it's so very easy to try different versions until one works.. WHY have we internet users allowed adobe to have sole control of a damn player?.. proprietary crap has no place on OUR internet!!!

My big production pile runs Sabayon 7 - 64 these days, debian betrayed us by going gnome3 abortion by default with FAR too many mono dependencies for my liking.. when you need something solid trust Sabayon Spot the linux user?.. Arch, ubuntu (yuck) Anubis (pretty cool but out of date) Sabayon and Slackware (server) messed with pretty much every day.. Just need a fedora box for the full house of package managers .. antique lappy runs BeOS5-PE (exotic enough for ya?)

I tested out the ubuntu 3.0.0 kernel (trying to solve the current bastard adobe shenannagins) and have to report that it's broken the wireless on this otherwise working lappy.. If it wasn't an experimental patched kernel trying to fix what turns out to be an unrelated flashplayer fatal error then I would be all over the ubuntu forums calling people unpleasant names (like crass amateurs who test nothing before release to main repos deserve!!) like a rash I promise..

 

well i did a clean install of the ubuntu 12.04 daily build instead, of course nothing has changed, i will try and remove the battery-monitor and network-manager and see if anything works. and what would i do about acpid?

 

Have a look in /etc/acpid/events/ to see if there is anything related to battery or ac_adapter event handlers. http://packages.ubuntu.com/precise/acpid would suggest that there isn't anything to blame there though. So probably not the cause in this case.

Have you tried a different desktop manager and/or network manager? Maybe try to see if the problem still exists if you use XFCE, or use Wicd instead of NetworkManager. Could be Gnome3 trying to be too smart for it's own good.

 

i have tried using xubuntu, and the same thing applies. therfore it is not an issue of which desktop environment i am using. i checked acpid and i dont think anything is wrong there, but then again i dont know what i am looking at. i reckon it is the kernel version. if i use any distro that uses the kernel 3.0 or later, i have a problem with the internet. such as ubuntu 11.10 and 12.04.

 

What make and model netbook are you using? There might be someone out in the interwebs who has identified and documented what the problem is.

 

the netbook is a Packard bell dot se-710uk. all the drivers work out of the box, and everything is running fine. it connects to the network okay and i made sure nothing has gone wrong. so it is definitely a software issue.

 

are you sure?.. could easily be a module conflict. I tried the 3.0.0 kernel on ubuntu and it broke the wireless connectivity which works just fine on the last 2.6 kernels. I think there is a wider problem here than ubuntu are admitting.. Everybody is reporting wireless and networking broken with the 3.0.x kernels, BUT.. you can always backport an older one with no real problems.. This lappy is rather "development and debug" setup.. as you can tell..

it could be the ubuntu kernel, i used fedora 17 alpha and it seems to work okay.

 

It is.. lots of problems with the ubuntu implementation of the 3.x kernels.. Heres a thought if you like a challenge. My Sabayon 7 (3.2 kernel) runs flawlessly so how about dragging in the sources from the Sabayon repos and compiling it up against the ubuntu libs and headers and seeing what happens?

I have had to revert to a 2.6 kernel on this to get any sort of sanity from both browsers and wireless.. it feels like a cumulative little fault has been growing. Afterdawn has been causing random browser crashes on ubuntu for a while, the later the kernel and flashplayer combination the worse it gets....... Take heart.. we are not alone..

https://www.google.co.uk/#hl=en&safe=off&output=search&sclient=psy-ab&q=ubuntu+3.x+kernel+wireless+broken&oq=ubuntu+3.x+kernel+wireless+broken&aq=f&aqi=&aql=&gs_nf=1&gs_l=hp.3...7724.18613.1.19067.33.31.0.0.0.0.1120.12238.0j6j9j4j6j3j0j3.31.0.Fo7cuR-BrO8&psj=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&fp=23c03c11b43e0d74&biw=1006&bih=638

I only got interested in the kernel problems due to a fatal browser problem which seems to be caused by that stupid flashplayer blob. Not quite solved yet with ubuntu, but I did fix it on my Arch lappy where things are a lot more standalone.
