Dell Studio 15 1555 Laptop Drivers for Audio, Bluetooth, Modem, Camera, Card Reader, Chipset, Video Graphics Mouse, Keyboard, LAN (Ethernet), Wireless LAN. Nov 17, 2010 How to fix sound IDT driver/headphone failure using Dell Studio. Reinstalling audio driver does not help * Audio test in Dell Diagnostics.

Hi guys, just registered as I have had already a lot of good use out of this forum. I don't expect to be able to help others as yet but am desparate to phase out windows 7 and get Ubuntu going again on this laptop. Problem is as follows: I have no wireless on my dell Studio 1558 and no sound (these are common problems as I have found). HW is BCM4312 (or 4315) chipset. Time Zero Uc Pool on this page. Funny thing is it worked before until I tried fixing the sound following the other topics on this forum with the evdev.c workaround. So after revising the driver myself I have no sound but also wireless stopped again plus my system froze constantly so I had to revert to the original sound driver.

I use Gnome and when I use NetworkManager it shows me that networking is enable but wireless is grayed out. No possibility whatsoever to convince Ubuntu to turn that option on. So I used the terminal. Doing iwlist - command gave me a nice scan of all the available wireless networks, but in the GUI I cannot get it to scan.

So my conclusion, the wireless HW is functioning, can scan but the GUI does not do anything. My questions: 1. For the workaround: how can I on the command line force the wifi to connect to my router? Can anyone help me to get the NetworkManager to function again? I have read quite a lot of topics on these two problems already.

The first time (before trying to fix the sound) the Dell support page on wireless was doing the trick for me. But that does not help me anymore. Thanks in advance for any help offered. Code: nm-tool sudo iwconfig cat /etc/network/interfacesSo we can see the details? I think you're going to find you've hard wired your interface in, which makes it invisible to NetworkManager, but there's a couple of other options. Sound is slightly more complicated at the moment, as I think it's changing in the Lucid (10.04) mix, so doing a whole heap of fiddling is probably a waste of time if you can wait a week for the beta. If you want to play, start with the sound troubleshooter; in my experience the trick is to open alsamixer (type it in a terminal) and find what's been defaulted to a level of 0.

Just for my learning, So far I understand the following (correct me if I am wrong): 1. Nm-tool shows the status of the networkmanager.

NWMan says eth2 is unavailable. Iwconfig shows the status of the wifi which says it is ok, just not connected. Cat /etc/network/interfaces shows the contents of the /etc/network/interfaces to see if wireless card is recognised as an interface, which it is not as it is not listed. Lsmod shows all loaded modules (including the wl module). Not sure what else to read from it. Lshw -C network gives a detailed view of the wifi card properties. Yes I am not so familiar with the command line stuff from Ubuntu/Linux which is what I really like to improve (playfully ).
