    Unhappy Netgear WPN824v2 crashes trying to connect with new Quantal install

    This thread appears to be the same problem with no replies:
    http://ubuntuforums.org/showthread.php?t=1913478

    Every time I try to connect wirelessly to my Netgear WPN824v2 router with my new Ubuntu install, the router immediately drops all connections. It works fine with a Windows 7 install and the same wireless card, so I'm suspecting the problem is with the router itself. I've been able to connect once or twice, but I can't reproduce connecting reliably, and both times the connection dropped within a minute and the router plotzed and dropped everything.

    My wireless card is a Realtek RTL8188CE 802.11b/g/n adapter. Strangely, it seems to be running on a rtl8192ce driver. I can connect via ethernet just fine. There are no firmware updates available for the router and dd-wrt doesn't support this model.

    Things I've tried:
    Code:
    iwconfig wlan0 rate 2M auto
    No change.

    Tried installing rtl8188ce driver from Realtek's website -- no help. Made sure build-essential and the appropriate kernel headers were installed, no help.

    It's been a week and my frustration is palpable. Any advice would be a huge help.

    I think you're on the right track in trying to build the latest driver from Realtek for your card. Their built-in kernel drivers are known to be problematic in 12.04 and 12.10.

    I just built the latest RTL8188CE driver from Realtek without errors in 12.04 (even though I don't have this card). People do complain about make errors, though. You probably need to install some development packages; I was building something else recently and installed a lot of development packages which is probably why I am now able to build the driver error-free. I could list all of the stuff I've installed but it's way more than you probably need to build this driver. If I can figure out what you really need, I'll post it but someone else has probably figured it out.

    FYI, it's common for 8188/8192 to be interchanged - I don't understand Realtek's naming methodology, but they tend to be used together. So I'm not surprised the kernel module uses for your wireless card is rtl8192ce, and I wouldn't worry about it. In fact, rtl8192ce is the name of the new module if you build that source code (for "RTL8188ce") like I did - there is no rtl8188ce module in the build. (Weird - yes.)

    Okay, I'll try it again; maybe I missed something in loading and unloading the kernel modules.

    Thanks for the pointer about the interchangeability.
