Modprobe brings back an error that the module is not found.

Man, oh man! I gotta scrape a few layers of grime off of these trifocals!

sudo modprobe r8192se_pci

If the prompt says nothing, then it has loaded successfully. Then, hopefully, connect with Network Manager.

[tracyandskye]

The prompt said nothing but the behaviour is the same. The wireless seems to work for a minute, then drops out. It shows a good signal & says that it's active, but it's not really working.

Please post:

iwconfig
ifconfig

Is the wired ethernet disconnected when it tries to connect? Thanks.

This is with the network cable unplugged & the wireless enabled & with a good signal

Man! Those are some great looking settings! I notice the card wants to do N speeds:

Bit Rate=150 Mb/s

Does your router support N speeds? Will it stay connected if you drop it down to G?

sudo iwconfig wlan0 rate 54M

N is a bit twitchy in Linux right now.

[tracyandskye]

It's working!!! I changed the router settings to G only.

Really sucks that Ubuntu/N is not quite there. I've had a D-Link DIR 655 router for a while & was so excited to finally get a laptop with N...

Thanks so much! If it were not for people like you, Ubuntu would not be an option for people like me. I need to get over to the absolute beginner forums & start helping.

Peace-

Hi,
I'm using Lucid, I have an Asus EEE 1201t and this wifi adapter.
It work only with revision -15 of the kernel, -16 and -17 (the actual) seems not to like my board; iwconfig sees the card but the scan sees no networks.
Any ideas about that?
Is this a known bug?

Bye!

bonjour

ça marche pour moi
j'ai téléchargé le pilote depuis ce lien

j'utilise ubuntu 9.10
Realtek RTL8191SE 802.11n PCI-E NIC

--- TRANSLATION ---
hello

it works for me
I downloaded the driver from this link

I use Ubuntu 9.10
Realtek RTL8191SE 802.11n PCI-E NIC

Hi folks,

Sorry for crossposting... but after a sleepless night I managed to make my connection working and stable.

Running Ubuntu Karmic (9.10) 64bit on Asus EEE 1201N with rtl8192se wifi interface.

A few days ago I bought a new wifi router, 802.11n capable. Since that time the connection was a nightmare. Drop-outs every few minutes, kernel panics, cold resets. I tried many driver versions from both https://bugs.launchpad.net/ubuntu/+s...ux/+bug/401126 and http://www.realtek.com.tw/downloads/, no joy. Ndiswrapper does not work for this network interface on the 64bit OS.

Finally, switching the router from WPA2 to WPA did the magic. Now running the latest driver from the Realtek web site,tThe connection has been rock stable, about 30 hours without a single drop-out, 150 Mbps.

Either the WPA2 implementation must be faulty in the device driver or there is a coincidence of the WPA2 and the 802.11n standard.

Cheers!
Ivo
