    Thank you for your kind comments. Let's have a peek under the hood. Please post:
    Code:
    dmesg | grep 819
    sudo iwlist wlan0 scan
    Thanks.

    Chili,

    Sorry, I didn't see 'Page 2' as an option and missed your reply. In advance, thank you for the help.

    As requested:

    mint@mint ~ $ dmesg | grep 819

    mint@mint ~ $ sudo iwlist wlan0 scan

    Hope that means something to you...I'm definitely stumped.

    Re: trying to install Netgear usb wireless adapter

    It means the firmware is properly loading. There may be several sizes. Let's see what you have:
    Code:
    ls -al /lib/firmware/rtlwifi
    Let's see what Network Manager is doing all this time. Try to connect and do:
    Code:
    sudo cat /var/log/syslog | grep etwork | tail -n25

    Re: trying to install Netgear usb wireless adapter

    Chili,

    I'm back online. Don't know if you got my last posting, as I'm writing this, it doesn't show up.

    It *does* connect! Found out if I got really, really close to the router, it does finally connect. Doesn't stay connect *long* or *far* but think we're making progress.

    Re: trying to install Netgear usb wireless adapter

    Well, wouldn't you know it. Problem! All the steps went fine this go around except the last command:

    mint@mint ~/Desktop/compat-wireless-2011-08-04-p $ sudo modprobe rtl8192cu
    WARNING: Error inserting rtl8192c_common (/lib/modules/2.6.38-8-generic/updates/drivers/net/wireless/rtlwifi/rtl8192c/rtl8192c-common.ko): Invalid argument
    FATAL: Error inserting rtl8192cu (/lib/modules/2.6.38-8-generic/updates/drivers/net/wireless/rtlwifi/rtl8192cu/rtl8192cu.ko): Invalid argument


    I'm stuck!

    Re: trying to install Netgear usb wireless adapter

    chili,

    Follow up with where the system is at today.

    >Upon reboot, the wireless light came on. So the last command not running, apparently cleared itself up.

    >Downed the machine over the evening; today, when booted, card's light came on and it did connect with router.

    >It's pretty flaky, overall, with it's communication. I'm about 15 feet from the router and only one room over. The laptop hits the internet slowly and haphazardly. You can be on Firefox and some screens will load quickly, sometimes they load as slow as if you were back on dial-up.

    Overall, we're *definitely* making progress. It's talking to the kernel, it hits the router, but it seems like there are definitely *tweaks* in store, perhaps from the authors of the actual driver itself.

    But it does work!

    Re: trying to install Netgear usb wireless adapter

    Please run and post:
    Code:
    lsmod
    modinfo rtl8192cu
    You should have rtl8192cu, rtlwifi, mac80211 and rtl8192c-common only loaded. Let's make sure there are no other wireless modules loaded that are conflicting. Also. is your network set to WPA and WPA2 mixed mode, which is often troublesome? WPA2 only is preferred.

    Re: trying to install Netgear usb wireless adapter

    Chili,

    Further update on today's happenings with the Netgear.

    Let the laptop go to sleep today, was out of the house a few hours. Upon returning, it awoke normal enough but the wireless option in networking is gone; i.e. only the 'wired network' option under the network dialogue box. So that's another issue, but I do know this: When you reboot and when you're close it does work, so that's some consolation.

    Output you requested:

    Re: trying to install Netgear usb wireless adapter

    Chili,

    Been running this, very stable, for 3 days. A few findings:

    When you reboot, all is well. It fires up the Netgear USB card, light is on and it connects.

    When the laptop goes to sleep (sleep, not hibernate) it doesn't come back. Light is off the Netgear, no getting it back.

    Anytime you're connected, and even when you're fairly close, it's a 'hit-or-miss' type of connection. It shows good connection in the dialogue box, but it may / may not always hit. Some web sites connect everytime, some do not.

    Still...it's getting somewhere at least.
