http://ubuntuforums.org – Hello, the wireless network connection of my HP 650 notebook is very unstable. I'm using Ubuntu 12.10 but the network was unstable as well with 12.04 (and even with the preinstalled SUSE Linux Enterprise 11). Here's some useful information about my system (I hope): Code: nm-tool NetworkManager Tool State: connected (global) - Device: wlan0  [Lagidium-viscacia 1] -----------------------------------------   Type:              802.11 WiFi   Driver:            rt2800pci   State:      &nbsp (Hardware)
