Dell Inspiron 1525 - Ubuntu - Wireless


Sorry, here is yet that same question. I have dual boot on Dell Inspiron Windows/Ubuntu. When I upgraded Windows to Win 7, a lost my wireless connection on the Ubunu side. The card is Dell 1397, which I understand is the BCM4312 underneath. Since I can't get Ubuntu to Internet, can I down load the right drive from Windows to C: drive and then pick up and install on Ubuntu side. Sorry to be asking this same ole question.

Tks if you have a relative simple and straight forward guidance.

Michael A.

If I'm not mistaken, we shouldn't need NDISwrapper (nor any .sys or .ini files) for a 4312, since either the wl driver or the STA driver should work. So the short answer is "yes", if you want to download something to Windows, then transfer it to the Ubuntu partition, you can do that no problem.

Just boot Win, download what you want, then boot Linux and mount the Windows partition, locate & navigate to the stuff you downloaded, and move/copy it to your Ubuntu system.

Note that the wl driver may already be present on the Ubuntu system; the STA driver however, you must get from Broadcom, and then compile & install it.

If this doesn't help, or if it's a different driver you believe you need, please provide further clarification.

PS - I'm not clear on why updating your Windows OS has interfered with your wireless from the Ubuntu end of things.. Maybe there's more to it than meets the eye, like maybe Windows shutting off the wireless device when it shut down, and Ubuntu not turning it back on.. Anyhow, if necessary, we'll dig deeper into this.

Dell Inspiron 1525 - Win 7 & Ubuntu 10.x lost wireless

Ah, yes thanks very much.

How can I check that Win 7 may be turning the wireless off and back on, such that it has been turned off when Ubuntu boots? Ubuntu does show on one form that wireless is disabled, and I was assuming the driver was missing, as the physical wireless switch reamains on when I reboot to Ubuntu.

Been there, done that.

'Missing your Wireless Drivers?' should get you up quick. The chipset for the bcm43xx has several subsets. Look at 'Slackware 13.0 RC2 X86_64 Broadcom bcm4312 problems' to possibly get some insight to help solve your problems. I know it's Slackware related but should provide details.
