[Bug 1063445] Re: Wireless not connecting, disconnecting
Hi, I haven't had any problems with wireless for a while now... I think things just started working after a upgrade a bit after I posted this bug. I can't remember when exactly it was (maybe a couple of months). So if you're having problems, I suggest you open a new bug... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063445 Title: Wireless not connecting, disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1063445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1063445] Re: Wireless not connecting, disconnecting
This same problem recently began happening to me on an Aspire One D270 running Ubuntu 12.04. The wireless was working fine, and then I ran a software update, and now wireless is completely hosed. (Another reason why I rarely run software updates...they tend to break more things then they fix). I also get messages in my /var/log/syslog about DHCPv4 timeout. This makes no sense, because I have a Macbook running Ubuntu 12.04 that works just fine with the wireless router the Aspire is unable to connect to. ** Changed in: network-manager (Ubuntu) Status: Expired = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063445 Title: Wireless not connecting, disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1063445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1063445] Re: Wireless not connecting, disconnecting
If there are MIC failures, it's likely that it's instead a bug in the kernel driver used. But just to be sure... Are you on battery when you try to connect? Is the behavior the same if the power supply is connected (e.g. can you successfully connect then?) There has been issues in the past coming from power saving modes on wireless devices, so this is worth testing. ** Changed in: network-manager (Ubuntu) Status: New = Incomplete ** Changed in: network-manager (Ubuntu) Importance: Undecided = Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063445 Title: Wireless not connecting, disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1063445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was plugged in when trying, not on battery, and it can be seen from lspci that power management is/was off ... (power supply state doesn't change this). It should work regardless, a netbook with no working wireless when on battery wouldn't be really useful :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063445 Title: Wireless not connecting, disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1063445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: When trying to connect to almost any wireless network, it never connects, the indicator just keeps moving until it says Disconnected a minute or so later. This happens 100% of the time with all encryped networks, and 99% of the time with unencrypted networks. I have so far have not been able to connect to an encrypted network, only unencrypted after several tries. - The very rare case when it does actually manage to connect (this is usually after trying to connect for an hour or so, many times beforehand, switching on/off the wireless with the hardware switch), it actually stays connected until you manually disconnect, and is also quite stable (downloads and PPTP connections work with no problem). + The very rare case when it does actually manage to connect (this is usually after trying to connect for an hour or so, many times beforehand, switching on/off the wireless with the hardware switch), it actually stays connected until you manually disconnect, and is also quite stable (downloads and PPTP connections work with no problem). Attached is a snippet of the old syslog from a few days ago when I was trying to connect, the current syslog doesn't have any relevant info as I am not near a wireless network currently.
