Realtek RTL8192E, Wireless not working

[chili555]

Do you have any other ideas?

I am concerned that there was no report, positive, negative or otherwise from:

andrew@ubuntu:~$ rfkill list all
andrew@ubuntu:~$

If you can get a temporary ethernet connection, please do:

sudo apt-get install rfkill
rfkill list all

I am running low on ideas.

Hello guys,

I have a Samsung N510 netbook running ubuntu 10.10 with a Realtek 8192e wireless card, and it's perfectly working thanks to chili555 explanations about how to blacklist a driver and using another driver.

So, I'm gonna share with you how I made it work.

First things first, do all the system updates using the update manager, so you will be running the latest kernel, which is 2.6.35-25.

After that, you'll need to add a repository, so you will have access to another driver for the rtl8192e.
Open a terminal, and run these commands :

sudo add-apt-repository ppa:voria/ppa
sudo apt-get update

Then, go into synaptics packet manager and search for "samsung-wireless".
Chose the package for install, and apply.

Last but not least, edit /etc/modprobe.d/blacklist.conf using whatever program you want, and add these lines :

blacklist r8192e_pci
blacklist r8192se_pci

EDIT : That's not "rtl8192", but "r8192", sorry guys !

Doing so will prevent the ubuntu embedded drivers from being loaded at startup and conflict with the driver you've just installed.
FYI, the "samsung-wireless" driver's name is "r8192e_pci_realtek".

Reboot, and voilà !!!
It should perfectly work, as I'm currently writing this message over my wifi connection

Oh, and I got all this information on Linux on my Samsung forum.

Guys, thanks so much for the help. After deciding that my hardware was simply not competent enough to properly run linux, I've installed Ubuntu on a virtual machine, which is working great so far.

Hello!

Sorry for hijacking Andrew's thread like this but I have a simmilar config/issue.

I'm running Ubuntu 10.10 dual boot on a Toshiba L515 laptop that uses Realtek 8192 driver for wireless. NM says wireless "device not ready" so I'm pretty sure that it's a conflict since:

~$ lsmod|grep 819
r8192se_pci           507324  0 
r8192e_pci            275601  0

and

~$ lshw -C network

now, i'm not sure if i should do what bightf suggested as a solution for his particular setup (Samsung laptop)?

Appreciate any suggestions!
thanks

[chili555]

bightf's suggestion looks good to me. It's reversible if it doesn't work as expected. Please proceed and let us know the outcome.

[bightf]

Even if the name is "samsung-wireless", the driver is pure realtek.

It's just because the driver is part of a set of packages made for samsung netbooks, but you can use this particular package with any notebook.

And yes, it's reversible anyway.

After installing this driver, I've tried to disable it and use the embedded "rtl8192e_pci" driver. It was not working at all, as I expected.

No change. I installed the "samsung" driver, blacklisted the two other drivers, - NM still says "wireless disconnected" or "wireless not ready"

the state is now like this:

:~$ lsmod | grep 819
r8192se_pci           512896  0 
cfg80211              170485  1 r8192se_pci
r8192e_pci            275604  0

any suggestions what should i do now? do I revert back? I didn't try blacklisting one of the original conflicting drivers but seeing that it didn't work in OP's case i wanted to try this option first.

the state is now like this:
Code:

:~$ lsmod | grep 819
r8192se_pci 512896 0
cfg80211 170485 1 r8192se_pci
r8192e_pci 275604 0

I think you should double-check and proofread your work. If rtl8192e_pci_realtek is NOT loaded and r8192e_pci and r8192se_pci ARE loaded, then you haven't installed correctly, nor have you blacklisted properly.

Last but not least, edit /etc/modprobe.d/blacklist.conf using whatever program you want, and add these lines :
Code:

blacklist rtl8192e_pci
blacklist rtl8192se_pci

Also, Network Manager will not allow wireless if wired ethernet is available; before you try to connect wireless, detach the ethernet cable.

Hi guys... I am relatively new to this... my old laptop died had been running
Ubuntu 9.04.... a little problem setting up then on an HP.

so I googled and came across this thread ..... sounds a lot like my problem, but not sure

I have a Toshiba Satallite A665D-S5175 I cannot get my Ubuntu 10.04 to detect the wireless.

I rebooted and I am wireless.... I do not understand.... just kept looking



worked on rubenp like mine a c660-10d bu the same RTL8101E/RTL102E


"I had the same problem with mi laptop toshiba c660 - 10d and its device:

as my sistem check says.
So I just typed the commands above, rebooted and ya está."



THANKS TO ALL WHO GIVE
