HI.

Just purchased a Toshiba Satellite L550D (after two failed HP laptops).
It has a "Realtek RTL8191SE" NIC card. After installing Fedora 13, niether the lan card or wireless card work.
I've searched thru this form and google in general but have been unable to find anything that has helped get the networking going.
"lspci" sees 'Realtek Semiconductor Co., Ltd. RTL8192SE Wireless LAN Controller (rev 10)'.
Any help would be much appreciated. I'm fairly new to linux on laptops.

How stuck are you on FC 13? I just bought a HP netbook, installed Ubuntu 10.4, and everything worked out of the box. In fact it is much faster than win-7 starter that came on it. You can get buntu in any desktop flavour you like. I installed the Gnome version.

I'm a little surprised the wired nic doesn't work out of the box. If you want to keep FC 13, then open a terminal window, and run the command '/sbin/ifconfg' and post the results.

Could you also run the command '/sbin/lspci' and post the results. That way we'll know about the wireless adaptor too.

Hi Cliff.

Thanks for the response. I would like to keep it at Fedora, as I have two servers at home that run Fedora.
I just finished re-installing Fedora 13 from scratch (in the event maybe I missed up something the first time). No difference, no networking at all. The weird thing is that I selected some of the repositories on the network during the install, and it seemed to work no problem. But after the install is complete, no networking.
Odd.......

Many thanks!

It appears your wireless card does have an IP address. 192.168.122.1, a mask of 255.255.255.0. Does this make sense for your network? If yes, can you try to ping either another system on your network, and or your router?

I'm guessing you have a router; or a ADSL modem/router. Is that correct? ( Or a cable modem/router ).

If you have a router, have you set up security? Encryption? Wep or WPA?

What do you get if you run '/sbin/iwconfig' ?

Hi Cliff.

Not sure what the 'virbr0' is. I can't ping anything (or use the internet).
I'm using a Rogers connection, which works fine when I boot the laptop in Windoze7 (wireless included).

iwconfig
lo no wireless extensions.

virbr0 no wireless extensions.

I now have the wireless card working, but not the wired NIC. How odd, to get the wireless working before the wired connection.
I found the wireless driver here:
http://www.wireless-driver.com/downl...rs-utility.htm

The driver downloaded was called "rtl8192se_linux_2.6.0015.0127.2010.tar.gz". Downloaded, untarred and followed the instructions in the readme.txt file. Upon reboot, wireless card works.

At least that will allow me to start using the laptop. Now to get the wired connection going......

Good stuff! Wired cards are less trouble that wireless; usually. I didn't see what type of wired card you have in the lspci listing. I guess it is connected on another bus.

Good luck with it.

When I boot the laptop in Windoze7 (dare I even say windows???), it sees:
Network Adaptors
Realtek PCIe FE Family Controller
Driver Provider: RealTek
Driver Date: 22/05/2009
Driver Version: 7.3.522.2009
Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC
Driver Provider: RealTek Semiconductor Corp.
Driver Date: 26/08/2009
Driver Version: 2006.2.826.2009

hmmm, oddly enough, the wired nic card is working now. I haven't changed anything.
The card now shows up in the lspci output:
14:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 0

The only thing that changed over the weekend was Fedora downloaded a bunch of patches. That must have fixed it, although I don't know what it did to fix it.
Nonetheless, both wired and wireless nic's are working.

Many thanks for the help!

Well, it's not solved. The wireless works perfectly, the wired nic doesn't.
Sometimes eth0 is present after a reboot, sometimes it's not. There doesn't seem to be a pattern.
When eth0 is not present, "14:00.0 Ethernet controller: Realtek Semiconductor" doesn't show up in lspci.

Those are symptoms of a hardware failure. Is this system still under warranty? If yes, and this persists, I would either take in back for repair, or replacement. From your first post it looks like Toshiba has some reliability problems.

I was originally thinking that, but if I boot the laptop in Windows7 (it's dual boot), both NIC's are rock solid.

There are some bugs reported against that card. The fix seems to be to download the new driver from here -->http://driverscollection.com/? compile and install.

If you google 'RTL8101E/RTL8102E' you will come up with lots of hits. Not sure when the new driver will be available through Synaptic.

Hi Cliff.

I originally downloaded the drivers right from RealTek:
http://www.realtek.com.tw/Downloads/...&GetDown=false

But these drivers all seem to be for the 'wireless' card, which is now working fine.

I appreciate all your help btw!

I have looked through this entire post. I don't see the wired lan card in any of the lspci outputs. I know some times it is there, and sometimes not.

Could you try to post the lspci when the card is visible. I have seen some strange bugs when a device will sometimes appear, and then disappear. Most often it is a card failing. However, I guess if the IRQ's are messed up, we might see the same type of behaviour. Lets look for the correct driver, try that, and go from there.
