    Wireless RT73 will not connect

    Hello,

    I have a USB rt73 generic wifi adapter installed, but this last time I turned it on it refused to connect to the router. I am not sure if I used the wrong drivers or if there is some conflict after some updates.

    It is connected via a USB PCI card, but it has worked. I am not sure where to look now since I have tried reinstalling the drivers several times with no luck. It just searches and searches but never connects even though the available networks are visible and the security information is entered correctly.

    I did configure my router to use MAC address filtering, and I believe I have the right address entered in my WNDR3300, but I don't know how to verify. This is the driver I downloaded and installed: RTL8188CE-VAU

    Re: Wireless RT73 will not connect

    I did configure my router to use MAC address filtering, and I believe I have the right address entered in my WNDR3300, but I don't know how to verify.
    Let's start at the easy steps and go on from there. Open a terminal and run:
    Code:
    ifconfig
    Here is an example:
    Code:
    $ ifconfig
    lo        Link encap:Local Loopback  
              inet addr:127.0.0.1  Mask:255.0.0.0
              inet6 addr: ::1/128 Scope:Host
              UP LOOPBACK RUNNING  MTU:16436  Metric:1
              RX packets:23 errors:0 dropped:0 overruns:0 frame:0
              TX packets:23 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:0 
              RX bytes:1569 (1.5 KB)  TX bytes:1569 (1.5 KB)
    
    wlan0     Link encap:Ethernet  HWaddr 99:19:d2:22:1b:88  
              inet addr:192.168.1.108  Bcast:0.0.0.0  Mask:255.255.255.0
              inet6 addr: fe80::219:d2ff:fec2:1b8d/64 Scope:Link
              UP BROADCAST RUNNING MULTICAST  MTU:1492  Metric:1
              RX packets:1727383 errors:0 dropped:0 overruns:0 frame:0
              TX packets:1124587 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000 
              RX bytes:2167115813 (2.1 GB)  TX bytes:142759544 (142.7 MB)
    The part I highlighted is the MAC address. Check yours in the router. Does it connect with MAC filtering temporarily turned off?

    Are there any clues here?

    Re: Wireless RT73 will not connect

    This is what I got when I typed in that last command- MAC address is correct.

    Re: Wireless RT73 will not connect

    And if you temporarily turn off MAC filtering, what does it look like?

    This is what it looks like with MAC filtering off:
