Hi all,

I just installed Hardy Heron (64 bit) on my new Gateway T1625 laptop and all is well except for my inability to get the wireless network working. (I have used Linux for some basic stuff before, so I'm not a total n00b, but the networking bit is new to me.)

I've gone through some of the documentation and determined:
a) Ubuntu does recognize my network card (RTL8101E), and
b) the r8169 driver is installed

However, when I go to System > Administration > Network, the wireless network doesn't show up as an option.

Here's the output to the lshw and iwconfig commands:

andrew@andrew-laptop:~$ lshw -C network

eth0 no wireless extensions.


I know wireless networking has been covered in a lot of other threads, but the info is fragmented, and I haven't found the solution to my particular problem yet.

By the looks of it that prefix looks to be a realtek card, can you give us more information?

Just a heads up, wireless + 64bit won't always work correctly. I had a 64bit Hardy install in which I installed the 64bit Windows drivers for my wireless card using ndiswrapper. This toasted the machine (mainly because I didn't test before adding the ndiswrapper module to /etc/modules).

Anyways, I grabbed a 32bit *buntu copy and loaded the 32bit Windows driver with ndiswrapper and everything worked perfectly.

Indeed, try that too.
You will have to re format again but it will probably work.

It is indeed a Realtek card. I don't have the specs with me right now, so I'll try and upload them later.

I should also mention that I was skimming around Realtek's website earlier and they claim to have a driver with 64-bit support:

http://www.realtek.com.tw/Downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false

(Scroll down to the Unix/Linux section and find the following description)
LINUX driver for kernel 2.6.X and 2.4.X (Support x86 and x64)

I don't know if anyone has experience working with this driver, but the instructions in the readme file don't seem compatible with *buntu 8.04 (though it does mention RedHat,Fedora, and SUSE by name)

If that doesn't work, it looks like I'll have to try the 32-bit version.
