I just bought a new Toshiba system, and before installing Ubuntu, I tried it out on a live CD. Unfortunately, Ubuntu doesn't recognize any wireless adapter.
$ sudo lshw -c network *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: ioport:3000(size=256) memory:c2400000-c2403fff
From the above output, I think that my Realtek wireless chip is unrecognized as what it is. But in my experience, all the Realtek devices worked out of the box. Furthermore, regardless of the manufacturer even if the appropriate drivers were not available, at least the devices were recognized for what it is properly.
Please help me resolve this issue.
Additional Drivers does not detect any proprietary drivers for me to install. (I have yet to install Ubuntu, and ran Additional Drivers after updating repository lists)
Wireless works on Windows 7 after installing necessary drivers. That is to say, there is no problem with the hardware, I'm befuddled why the hardware is not recognized at all (refer to the
lshw output above). As far as I am aware, even hardwares requiring proprietary drivers to function would at least be recognized in
lshw output and such.
