    Question *HELP* Cannot find or connect to my Wi-Fi but I'm able to see others.


    Hi Ho!

    I've just decided to migrate from Windows to Linux, but I've came across a very annoying problem. The thing is (It's the same in both openSuse and Linux Mint) when I try to connect to my Wifi, I can't find it. But I can find several other WiFi’s that are from my neighbors.

    It's not hidden or anything and its using channel 3 so that shouldn’t be a problem. I have a D-Link DWA-140 USB adapter, the Router is a D-link DIR 655 Xtreme N Mixed, so it's broadcasting on B, G and N and the security on it is WPA2-PSK. I won't change the security to WEP = then I lose around 80% of the internet speed which I don't want.

    I've tried as I mentioned above both openSuSe and Linux Mint (Mint is currently installed on the computer) and the result is the same. I've installed Wicd instead of Network Manager and it's just as before.. What the hell am I doing wrong?

    So I decided to ask you guys here, hopefully I can get this to work, otherwise I'll have to install Windows 7 again

    Hello and Welcome,
    I know it seems like a lost cause sometimes because these things can be frustrating. I advise you to start here and post the relevant info back into this thread for more assistance. It starts at the beggining so we can make sure you have all the correct drivers and settings.

    Can you connect to other wireless networks?

    I'm not sure if this is related to your problem, but I see two sets of drivers loading for your wireless.
    Code:
    Module                  Size  Used by
    rt2870sta             488820  0 
    <snip>
    rt2800usb              37372  0 
    rt2x00usb              11548  1 rt2800usb
    rt2x00lib              29756  2 rt2800usb,rt2x00usb
    led_class               4096  1 rt2x00lib
    input_polldev           3716  1 rt2x00lib
    mac80211              181236  2 rt2x00usb,rt2x00lib
    cfg80211               93052  2 rt2x00lib,mac80211
    The rt2870sta is a different driver than the rt2800usb and rt2x00 driver. Usually when two drivers compete for the wireless, it won't work at all.

    I don't know which driver it is currently using, but the rt2800usb is requesting firmware:
    Code:
    [   28.697149] rt2800usb 2-5:1.0: firmware: requesting rt2870.bin
    So, I will assume that is the working (?) driver. Check the /lib/firmware directory for a file named rt2870.bin. It also may be in one of the sub-folders in that directory. If you can't find it, look for it with this command.
    Code:
    locate rt2870.bin
    If you can't find it, you may need to install it.

    Try blacklisting the rt2870sta driver, to see if it has any positive effect. Open gedit with root privileges, and edit the blacklist file.
    Code:
    gksu gedit /etc/modprobe.d/blacklist.conf
    Add this line to the bottom of the file.
    Code:
    blacklist rt2870sta
    I would then reboot, and run the wireless setup script again. Please delete or rename the original wireless_setup.txt file. Otherwise it will add the new info to the old file. If this is worse, then you should blacklist the rt2800usb/rt2x00 drivers and unblacklist the rt2870sta driver and reboot again. Kind of like this forum member did here:

    http://www.linuxforums.org/forum/wir...wusb100v2.html

    Except he is using the rt3070sta driver, and you aren't.

    I had a little time to look at this further. It appears that both of the drivers support your wireless. If you check the modules using the modinfo command the ID number shows up on both:
    Code:
    paul@Zotac-SAM:~$ modinfo rt2800usb | grep -i v07D1p3C09d
    alias:          usb:v07D1p3C09d*dc*dsc*dp*ic*isc*ip*
    
    paul@Zotac-SAM:~$ modinfo rt2870sta | grep -i v07D1p3C09d
    alias:          usb:v07D1p3C09d*dc*dsc*dp*ic*isc*ip*

    Anyway, what I meant to say was that either of these drivers should work for your wireless. The rt2870sta driver is a proprietary driver. The rt2800usb driver is an open source driver, and part of the kernel. It does require the installation of firmware, which is proprietary. It can be downloaded from Ralink.

    Ralink corp.

    It is up to you which driver you want to use.

    Thanks for quick response!

    Okey so I've uppdated the drivers for the wifi dongle (the one from ralink) and the resaults are just as before... The wifi addapter works somewhat ((I think)) but it can't find any networks with VPA2 encryption

    I tried to remove the encryption and BAM I found the network (just as before), but I couldn't connect to it, it just keept on loading until it said; Disconnected from ####. But I don't want to have an unsecured network, and WEP is not an option

    Sorry if I got something wrong, read it all on my iPhone (wrote this on it aswell) forgot my laptop at school.

    Did you blacklist the driver that you are not using? It may not solve your problem, but it isn't a good idea to have two drivers loaded for one device.

    Yeah I've done that, also tried to follow that guide that other guy did, but with a little twist as I'm using the driver he tells you to blacklist. But yeah, I've blacklisted the driver I'm not using, so I avoid any futher conflict :P

    Double check that you only have one driver loaded, using the lsmod command.

    If you are having trouble when using the rt2870sta driver, then try blacklisting that one and use the rt2800usb driver. Maybe that would work better. It will need the firmware, so make sure you have that. You also said that you tried Wicd. There may be a setting that you need to change to connect to encrypted networks. I don't use Wicd, so I can't tell you exactly where to find that setting.

    Often when others have this problem, it turns out that the had been using an incorrect password. They will swear up and down that they have the password correct, only later to find that they DID make a mistake. Can you connect to any other WPA networks?

    The WPA encryption is handled (usually) by wpa_supplicant. Make sure that you have that installed. Maybe Wicd needs this before it can connect to an encrypted network.
