    Default Very strange WiFi problem

    I have recently bought a new wireless card. It is one of these:
    Edimax EW-7612PIn - 300Mbps Wireless 802.11b/g/n PCI Express Adapter an Edimax EW-7612Pln.

    It is installed, here is the lspci:

    Code:
    Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller [10ec:8172] (rev 10)
            Subsystem: Edimax Computer Co. Device [1432:7612]
            Kernel driver in use: rtl819xSE
    I got the driver from the openSuse wireless repo, here:

    Index of /repositories/driver:/wireless/openSUSE_11.4



    I can connect with it, but not use it. If I
    Code:
    ping -c5 bbc.co.uk
    It takes a while, and then pings.

    I cannot use Firefox, email, zypper etc etc.
    I can start and use IRC with konversation!!!
    When I first got the card I tried to install the driver tarball supplied by the maker (make, install, etc) this was before I was aware of the existence of a repo.
    I think I uninstalled that (?) I have no experience of installing/uninstalling drivers this way.

    lsmod |grep r8
    r8192se_pci 541224 0
    I don't wish to fill this page with entire dmesg or /var/log/message
    but I can provise them if they would help.
    Whilst trying to get this working, I have noticed that ifup at terminal shows these warnings:
    l
    Code:
    inux-p9sz:~ # ifdown wlan1
        wlan1     device: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)

    Also in dmesg, this:

    We won't be able to help you very much. Vendor drivers are generally ****. I
    have a good version for the RTL8192SE/RTL8191SE that I am getting ready for
    submission to the kernel. It came from Realtek via back channels; however, it is
    not the same as the one on their web site. It would already have been submitted,
    but it crashes my computer.

    Surely it can be made to work? I am sure that your driver will be brilliant when it is finished, but until then?

    There must be 1,000s of people using this chip already, many laptops/netbooks have it installed. Indeed the wee shuttle PC I linked to here:
    Tiny, silent Shuttle PC boasting full openSuse compatibility Has it and is tested and proved to work with openSuse .
    The adapter connects, and even reports "connected at 300Mb" but cant surf the web. I can ping an ip no prob. Surely this is working except for a tiny tweak or two?
    Do any of the ! warnings in dmesg mean anything to anyone?
    ie '
    Code:
    RX: IEEE802.1X EAPOL frame!
    '
    and:
    Code:
    'InitializeAdapter8192SE(): Set MRC settings on as default!!'
     'HW_VAR_MRC: Turn on 1T1R MRC!''
    '

    and what of the ifup messages:
    Code:
    ifup wlan1
        wlan1     device: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)
        wlan1     warning: WPA configured, but is untested
        wlan1     warning: with this device
        wlan1     starting wpa_supplicant
    ioctl[SIOCSIWAP]: Operation not permitted
    ioctl[SIOCSIWENCODEEXT]: Invalid argument
    ioctl[SIOCSIWENCODEEXT]: Invalid argument
    Starting DHCP4 client on wlan1. . . .  
        wlan1     IP address: 192.168.1.68/24 (linux-p9sz)
    Should I be pursuing any of these to get to the bottom of the problem?
    Is there nothing I can do except wait for kernel 2.6.40?

    ps I tried to make it use google dns (8.8.8.8 and 8.8.4.4) but it did not seem to solve it.

    Are you running opensuse 11.4? You said that's the repository you used, but it lists 11.2 as the opensuse version in your signature line, or whatever you may call that.

    also when you uninstalled the driver you compiled, did you run from within where you made the make file "make uninstall && make clean" ? if you didn't run make uninstall then you didn't get rid of the old driver, nor their files and config's.

    I believe it is a DNS problem. In firefox please paste:
    Code:
    216.239.51.99
    in the address bar and hit enter.

    [EDIT]
    After reading "I can ping an IP address fine" it is definitely a DNS problem. I'm not openSusing at the moment so I can't, but surely someone can tell you how to add dns servers to your system.

    [EDIT 2]
    In a terminal:
    Code:
    dhcpcd wlan0
    may solve the problem. Also, zypper uses a URL not an IP.

    TY rodhuffaker, I am indeed running 11.4, I have not got around to updating my sig yet. I will do that now. Well spotted!

    I did 'make uninstall' but I did not do 'make clean' I have since deleted the downloaded driver files and the dir. they were in. I think perhaps you might have hit the nail squarely on the head here. I am going to try with an empty drive a *110% fresh* install of openSuse and see if it works there.

    bsilvereagle. TY for the reply. I have tried various ways re. 'DNS' and none have improved things. I have tried forcing the card to use googleDNS at 8.8.8.8, 8.8.4.4.
    The card acquires an address from the router no prob.

    Hopefully your fresh install solves the problem.
    If not, please list all of the methods you have tried. Such as Yast, /etc/resolv.conf, etc.
