View Full Version : [ubuntu] Wireless Issues with Intel 5150 -- Ubuntu 10.04 and Windows 7 on Dell Studio

Hi All --

I am having extensive wireless issues with my computer. I have a Dell Studio 1737 with dual boot Windows 7 (32-bit) and Ubuntu 10.04. I have an Intel 5150 WiFi/WiMAX card that has been working fine since I got it (using it for WiFi, not WiMAX). Suddenly a couple months ago, the wireless stopped working, while I'm running either Windows or Linux, and neither will let me enable wireless. Windows tells me to turn on the wireless switch (which does nothing), and Linux won't let me click the "Enable Wireless" option. I had my computer looked at by Best Buy, and they told me that it is not a hardware issue, but a software one that has to do with the drivers, which I've reinstalled since, and no luck.

Does anyone have any advice/experience with this kind of issue?

Thanks,
AgentZeta

Welcome.

Sure sounds like hardware to me. Did it die in both OSs at the same time?

Could you run this in a terminal (Applications>Accessories>Terminal):


lspciLook for the line that starts 'Network Controller', probably somewhere near the bottom of the output and post it back here. If your wireless card is missing then the hardware is probably dead.

You can get more specific with:


lshw -C network

That will tell us the driver you're using and some other info.

Thanks for the quick response.
Here's what I have from that:


04:00.0 Network controller: Intel Corporation WiMAX/WiFi Link 5150 Series

From what I can tell, the hardware's there. I can see that from Ubuntu and from the Windows Device Manager as well.

Here's the rest of the lspci if you want it --
