I was looking into your logs and I can seen lots of errors/warnings related with your network driver:
[46699.009858] rtl8192c_set_FwPwrMode_cmd(): Mode = 0, SmartPS = 0 [46700.769573] survey done event(2d) [46702.577247] rtw_set_ps_mode(): Enter 802.11 power save mode... [46702.577294] rtl8192c_set_FwPwrMode_cmd(): Mode = 1, SmartPS = 2 [46819.009166] rtw_set_ps_mode(): Busy Traffic , Leave 802.11 power save.. These could be the cause of your problem. So, since the kernel you're using is quite old now, and a lot of changes have been done to your network device driver since kernel 3.2.0-23.36 (this kernel has been released in April!), I would suggest an upgrade. Something like: $ sudo apt-get update $ sudo apt-get dist-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064343 Title: system works very slowly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1064343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
