I have recently installed UBuntu and I'm having problems with my (RTL8190) card.
I followed the steps listed here - https://help.ubuntu.com/10.04/internet/C/troubleshooting-wireless.html
After using the command "sudo lshw -C network" I got the following output:
*-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 06 serial: 10:78:d2:73:9f:0d size: 10Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=rtl_nic/rtl8168e-2.fw latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:d800(size=256) memory:f8fff000-f8ffffff memory:f8ff8000-f8ffbfff *-network UNCLAIMED description: Network controller product: RTL8190 802.11n Wireless LAN vendor: Realtek Semiconductor Co., Ltd. physical id: 1 bus info: pci@0000:04:01.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=64 maxlatency=64 mingnt=32 resources: ioport:e800(size=256) memory:fbfff000-fbffffff
I proceeded to install the ndisgtk package and downloaded the "net819xp.inf" driver.
Using the windows wireless drivers app. I selected the .inf file but it said there was an error. I attempted to select it again but it said it was already installed. When I run the original command again it still lists the card as 'UNCLAIMED'.
Anyone know how to get it working? Thanks.
