http://askubuntu.com – I have installed 12.10 on HP ProBook 4740s but i cant get wireless (wifi) working. After booting to Ubuntu, wireless network is by default down and even when I switch it up, it is not visible in network options in top right corner. It is also not possile to connect from terminal, because no wireless networks are found. So it seems that wireless is somehow installed but probably not properly. Do ou have any advise pls? When I run lspci -v I get: 04:00.0 Network controller: Ralink corp. Device 3290 Subsystem: Hewlett-Packard Company Device 18ec Flags: bus master, fast devsel, latency 0, IRQ (HowTos)
