    Low Wireless signal strength WLAN 1510 Studio XPS 1340 - Laptop General Hardware Forum - Laptop - Dell Community with a picture. And so I thought that reducing the power consumption (for the time of the download) might be a way to give Prad_viking a better chance for a undisturbed sleep.

    But Carl and Larry have far more experience so it is probably better to follow their advice.

    Good luck

    AFAIK, the setup of the display system is correct. If the wireless shuts off
    when you close the lid, then it is something built into the hardware of the XPS,
    or it is a function of dell-wmi. In either case, there is not much we can do.
    You will need to find a workaround that does not involve closing the lid.

    Thanks a ton all of you. Really appreciate the help provided by all of you.

    Anyway to come around this problem, I have created a new profile under the Power Management which dims the screen brightness all the way down in just 2 minutes so that by the time I hit the sack the screen is off.
    (but I have to remember to activate it every time )

    I just had the same problem. Typically I close the lid on my laptop and have it set to turn off the screen. Then open it up and the wireless reconnects. Tonight at my parents, i did this to go eat dinner, otherwise my new puppy will lay across the keyboard and palmrest cause they're slightly warm. When I came back from dinner, picked the puppy up off the closed laptop (I guess he just considers it his resting pad) my wireless came up and will not connect. The symbol by the clock is a red "no" circle and the only thing I know how to do in the network connection manager is remove and redo the wireless but that had no effect either. I'm fairly new to linux so any help is appreciated.

    Using the info in the sticky it shows correctly with the device and firmware, and the scan (sudo /usr/sbin/iwlist scan) shows:

    that's the SSID for my parents wireless. I was connected and doing a college course before dinner. I need to reconnect and finish that course by tomorrow night for full credit.

    The sticky also said that I could delete the wirelss and reboot to have Suse recognize the wireless again and reconnect. How do I do that?

    My stuff:
    Dell Inspiron n5010
    Centrino Wireless N
    OpenSuse 12.1 KDE (updated as of 4/1/12)

    I fixed my problem. After reading the stickies and the thread that Oldpcu had on his broadcom wireless, I logged in as root, went to etc/networkmanager/ and deleted a text file there (can't remember the name and it's not in my trash) then went to etc/networkmanager/system-connections/ and deleted the text file for my parents SSID. Then opened network manager, scanned for wireless and it found my parent's wap again. I'm connected once more and off doing horrid homework assignments
