    Question rtl8192se - Wireless Problems on 1201N

    Hi there,

    I'm currently using Ubuntu 9.10 on my brand new Asus Eee PC 1201N, everything was working great till a couple of days ago, when wireless decided not to work anymore.

    Wireless connections still appear on network-manager list, but when I select one, it shows me a popup message with "Wireless network Disconnected".

    I did not change anything in network-manager, and according to the settings I have on my old laptop, which has a different wireless card, everything is ok.

    So I really don't know if this is due to some problems on network-manager or, wireless drivers.

    I would appreciate if someone could give some tips on how to solve/debug this problem.

    Below are some system informations!

    Re: rtl8192se - Wireless Problems on 1201N

    I am having the same exact problem with Ubuntu Netbook Remix 9.10 with my Eee 1201N. I also setup wireless with NDISWrapper. It was working with a router that uses WPA encryption, but now it doesn't want to connect. I could never get it to work with another wireless router that uses the older WEP security.

    Please see here:
    eth0 Link encap:Ethernet HWaddr e0:cb:4e:39:92:e0
    inet addr:192.168.0.105 Bcast:192.168.0.255 Mask:255.255.255.0
    Also see here: https://help.ubuntu.com/community/NetworkManager0.7

    Especially this:
    The computer should use the wired network connection when it's plugged in, but automatically switch to a wireless connection when the user unplugs it and walks away from the desk. Likewise, when the user plugs the computer back in, the computer should switch back to the wired connection. The user should, most times, not even notice that their connection has has been managed for them; they should simply see uninterrupted network connectivity.
    You are being 'managed.' Please unplug the ethernet cable and try the wireless again. It may take a reboot.

    Re: rtl8192se - Wireless Problems on 1201N

    Take a look at post #35 from brocie in this thread here. It looks like ndiswrapper doesn't work well with kernel 2.6.31 (and some earlier ones).

    I have a Mythbuntu 9.10 system (based on xubuntu, but this seems to fairly common within ubuntu distros) and a TrendNet TEW-643PI (rlt8190 chip). First when I installed it (and used wicd, seems to work much better than network manager) it worked fine. Since then, it was hit of miss (mostly miss) whether it connected. Seemed to help to turn my router off and then on. Didn't matter whether I used DHCP or static IP (typically worked only once in ~50 attempts).

    Since I installed the 2.6.32-10 kernel it works every time. The only thing that now doesn't seem to work is my remote on my Mythbuntu box but that is probably something that can be easily fixed.

    Note that 2.6.32 is for 10.04 it is not officially compatible with 9.10.

    I guess everyone is hoping for a backport to 2.6.31 but given the status of the wifi on Ubuntu I doubt that will happen.

    Hope this helps.

    Re: rtl8192se - Wireless Problems on 1201N

    I found a solution to get wireless networking to work without NDISWrapper! I went to the following link to figure it out:

    https://bugs.launchpad.net/ubuntu/+s...6?comments=all



    I used the rtl8192se_linux_2.6.0010.1211.2009.tar.gz file which was referenced in post #134 and is available here:

    http://launchpadlibrarian.net/366886...11.2009.tar.gz


    I did the following to get it to work after downloading the file:
    Code:
    tar xzf rtl8192se_linux_2.6.0010.1211.2009.tar.gz
    cd rtl8192se_linux_2.6.0010.1211.2009
    sudo make
    Then you need to edit two files to work with Ubuntu using the following commands (This works on Ubuntu 9.10):
    Code:
    sed -i 's/install: modules/install:/g' ./ieee80211/Makefile
    sed -i 's/install: modules/install:/g' ./HAL/rtl8192/Makefile
    Then you install with the following command:
    Code:
    sudo make install
    sudo echo "r8192se_pci" > /etc/modules
    sudo modprobe r8192se_pci
    Your wireless should now be working. Make sure to remove the NDISWrapper driver before doing this if you have already installed and set it up.

    Hey Much Thanks CompMAS2 That was the bit of code I was missing...Now the Network Manager see's my card and connects automatically to my network... ...Any Reason I have to keep unlocking the Network Manager key ring after reboot?? hmm

    Re: rtl8192se - Wireless Problems on 1201N

    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
