    Re: Can't get Realtek RTL8191SEvB wireless adapter to work

    Unfortunately, this does not work for me.

    However, it produced some changes of the wi-fi behaviour. When I follow your instructions Network Manager indicates that wireless is disabled and when I enable it, it is "disconnected" but, immediately after that wireless is disabled again and keeps disabling automatically.

    Do you have an idea what might be the cause of this behaviour?

    Re: Can't get Realtek RTL8191SEvB wireless adapter to work

    I still haven't solved this issue.

    When I unload and load the r8192se_pci driver with the hwwep=0 option:

    Code:
    rmmod r8192se_pci
    modprobe r8192se_pci hwwep=0
    And then, when I enable the wireless via the Network Manager, it says that the "device is not ready". I've found some suggestions that this is an issue caused by the rfkill blocking the wireless, so I've unblocked it:

    Code:
    rfkill unblock all
    So that it was unblocked:

    Code:
    1: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    After re-enabling the wireless, at first Network Manager reported "disconnected" for the wireless networks, but immediately after that, inspecting the Network Manager the second time, it returned back to "device is not ready" message. I guess something must have been reset back to its original value.

    Re: Can't get Realtek RTL8191SEvB wireless adapter to work

    I have news. After I have installed newer Realtek's driver (rtl8192se_linux_2.6.0019.1207.2010), the wi-fi still doesn't work, however it is not disabling itself all the time.

    So, when I sudo modprobe r8192se_pci and enable the wireless via the Network Manager's widget, it is "disconnected" with no wi-fi networks found.

    Code:
    $ iwconfig wlan0 
    wlan0     802.11bgn  Nickname:"rtl8191SEVA2"
              Mode:Managed  Access Point: Not-Associated   Bit Rate:130 Mb/s

    I have given up on trying to make it work, not having the necessary know-how. But I'm still hoping you or someone will work out a solution, because even though windows 7 is better than vista, it's still inferior to Ubuntu.

    Re: Can't get Realtek RTL8191SEvB wireless adapter to work

    I recently bought an Edimax 300Mbps Wireless (model #EW-7612PIN) which also uses the RTL8191SEvB chipset for a new build of mine.

    I'm running ubuntu 10.10 x64. After a fresh install, I can confirm that this card is working for me!

    Kernel is:
    Code:
    Linux black 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux
    Running lshw -class network gives:

    And running lsmod | grep r8192 gives:

    And iwconfig wlan0 gives:

    I can browse the net which is a little slower compared to my win7 laptop. File transfers over samba seem pretty good, averaging about 1.1MB/s. My wifi network uses WPA2 encryption as well. The only problem is that the bit rate seems to be stuck at 1 Mb/s and running sudo iwconfig wlan0 rate 54M doesn't seem to do anything.

    I'm available to run commands for others who are trying to get this card working - so feel free to ask me! (Seems a bit of a fluke that mine worked

    I have exactly the same problem with the same wireless card (RTL 8191 SEvB) in Thinkpad Edge 13 and installed Ubuntu 10.10 64b will be great pleasure if it can work with wireless internet

    I have the same card on my Toshiba L505-10M with Ubuntu 10.04 64b. It worked well out of the box from day 1 some 10 months ago. I do use an earlier software version however < driver=rtl819xSE driverversion=0015.0127.2010 firmware=62 >. Hope this helps.

    All problems were solved with the bios update and upgrade of the Linux kernel!

    If a post is older than a year or so and hasn't had a new reply in that time, instead of replying to it, create a new thread. In the software world, a lot can change in a very short time, and doing things this way makes it more likely that you will find the best information. You may link to the original discussion in the new thread if you think it may be helpful.
