Ubuntu Networking :: Dell Inspiron 15r (n5010) Wireless Disabled?

Sep 30, 2010

i have to say that i'm not too familiar with Ubuntu... or Linux in general . I've installed it once, just to test it out but I didn't know how to use it so i just reinstalled windows. The other night, i was bored and decided i wanted to re-try Ubuntu and to my suprise, i found Wubi. I love ubuntu now and i made the decision to permanently switch over to ubuntu.

At first, my wireless wasn't working, but there was a quick fix. All i had to do was go to the Synaptic Package Manager, Reload, and search for "Broadcom." I installed the Broadcom STA Wireless driver and i was online within a couple of minutes. I then played around for a couple of hours before turning my laptop off. But, this morning, when i turned it back on...I coudlnt' connect. When i click the little connection icon in the top right, i see the message "Wireless is disabled".

There is a key on my computer that turns the wireless card on or off, and i have tried it. It doesn't work. I have reinstalled the broadcom driver and it doesn't work. I've rebooted...And it doesn't work. I don't know enough about linux to get a solution and every other solution i find on the internet doesn't work.

I have seen in other threads that you guys usually ask for a a couple of things from the user. ifconfig and the sudo lshw -C network so i have included them below. I also looked into the ubuntu help documentation and it told me to do the lspci command.

ifconfig

Code:
eth0 Link encap:Ethernet HWaddr a4:ba:db:d1:61:c2
inet addr:192.168.1.68 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::a6ba:dbff:fed1:61c2/64 Scope:Link

Ubuntu Networking :: Wifi Not Working Dell Inspiron N5010 And Broadcom 4313

Dec 24, 2010

ok basically i have a new dell inspiron n5010 with a broadcom 4313 wifi card. it doesnt work with ubuntu studio 10.10. I have the drivers all installed and it works on ethernet with the broadcom STA proprietry driver. if i disable this driver the eth doesnt work. but the driver shows its working (screenshot-1).

There is no pop up or anything in the task bar for detected wifi. i open the network settings and it shows up with a wifi option but i have to go into properties and manually type in what i have "the_den_meribel". which didn't work. (screenshot-2).

i have tried the other driver broadcom-sta-common and that doesnt make it work either. screenshot-3. i did try to install the "lp-pphhy" or whatever it is (seacrh for firmware-b43 in synaptic).

i have a list of results from what i have typed into the terminal: dell inspiron n5010

Code:
sam@drytopubuntu:~$ lspci
00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18)
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)

Ubuntu Networking :: No Ethernet Or Wireless Dell Inspiron 1764?

Jun 17, 2011

I'm running on 11.04 on my Dell Inspiron 1764, and so far haven't been able to achieve internet access through either a direct wired connection or wireless.

Wireless network controller: Broadcom BCM4312 802.11b/g LP-PHY (rev 01)

Ethernet controller: Realtek RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)

Fixes I've tried so far:

Wired - Attempted to install the r8168 driver and remove the r8169 driver as is done in this thread:

url

Wireless - managed a fleeting wired connection yesterday, during which time I installed the Broadcom STA driver through Additional Drivers.

Also attempted to install the firmware-b43-lpphy-installer, following these instructions:

url

but to no avail (under Synaptic Package Manager, the firmware-b43-lpphy-installer still remains unchecked after I install it through terminal)

Ubuntu Networking :: Wireless Not Working In 9.10 Using Dell Inspiron 600m?

Jan 7, 2010

The network icon and sound icon disappeared from the panel all of sudden one day while i was using ubuntu 9.10 and the network got disconnected. It used to work fine before when i was using ubuntu 9.04 and even after i updated to 9.10, but then that happened. I added the notification area back to the panel but now ubuntu cannot even find any wireless networks. When i connect a LAN cable to my laptop the internet works fine, but the wireless networks area in the network icon is grayed out and it doesn't show any wireless networks. I'm using a Dell Inspiron 600m laptop and my network card is Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection (rev 05).

Ubuntu Networking :: Re-enable Wireless On Dell Inspiron 1545?

Jun 12, 2010

I've got a Dell Inspiron 1545 with wireless card Dell wireless 1397 802.11g. It was working fine with Windows and Ubuntu 9.04 (I've got the two OS installed alongside). But as soon as I upgraded my Ubuntu to version 10.4 I realised it lost its wireless connection! I updated the system, the hardware driver for Broadcom STA wireless driver is activated and in use (according to Ubuntu Hardware drivers checker) but the fact is that I can only connect on the Internet if I hook the net cable on it, when I run the mouse over internet connection icon at the topright side of the monitor I see "no network" message and when I left click on it the option "wireless network" it's disabled and gray. How can I get my wireless card back working?

Ubuntu Networking :: Not Detecting Wireless Networks On Dell Inspiron Mini 10?

Jul 6, 2010

I recently installed Ubuntu Netbook Remix on my Dell Inspiron Mini 10, and for some reason it isn't detecting any wireless networks. The wireless works perfectly fine when I boot to Windows XP on the netbook, but not when I'm using Ubuntu. I tried troubleshooting using this htmlAt the "check for device recognition" step, the terminal tells me that it's disabled, but as far as I can tell there isn't a physical switch that allows me to turn the wireless on or off, and again, it works perfectly fine when I use XP. What should I do?

Ubuntu Networking :: BCM4312 802.11b/g 9.10 Dell Inspiron 11 Wireless Driver Now Missing?

Mar 1, 2010

I tried to find my solution for hours now but no luck. I'm a medical student and the other day I finally found the time to set up ubuntu for my first time. Everything was working great and I had wireless up and running. However, I tried to set up tethering to my iphone and after that my wireless hasn't been working (I've noticed no other problems). [URL]..Then I used this tutorial [URL].. However, after doing these steps the computer needed to reboot (I actually forget exactly where but I had to reboot in the middle of the second tutorial). After my computer restarted my wireless no longer showed up. By this I mean that wireless network no longer even showed up as an option when I left clicked then connections. However, I did not lose the wireless profile under network connections. So I went to system and noticed that the Broadcom STA driver was no longer active. So I tried to activate again and received this message.

Ubuntu Networking :: Neither Wired Nor Wireless Working Dell Inspiron 1545

Jul 27, 2011

I just installed Ubuntu 10.04.1 on my Dell Inspiron 1545 laptop, but I can't connected to the Internet with a wired or wireless connection. I have a BT Home Hub 2 wireless router. I can connect to the Internet when running Windows Vista, but not with Ubuntu.

I tried installing the Broadcom STA driver off of the live disk, which initially seemed to work. However, I still couldn't connect to the Internet and when I clicked on System > Administration > Hardware Drivers, there weren't any proprietary drivers to install or that had been installed. Also, when I reboot, Ubuntu tries to connect to my network automatically but always fails. That's what makes me think that a driver has been installed, but just isn't the right one or isn't working.

Networking :: Dell Inspiron 1545 Ethernet And Wireless Won't Connect On Ubuntu Studio

Sep 14, 2010

I have a Dell Inspiron 1545 with a Dell Wireless 1397 WLAN Mini-Card and a Marvell Yukon 88e8040 PCI-E Fast Ethernet Controller, and I cannot for the life of me get the internet to connect. I've tried both wired and wireless connection. I have a PPoE connection through a Verizon FIOS Actiontek router I believe, though the PPoE part may be wrong, I had one five years ago when I first got their internet so they may have changed it. Point is that the ethernet and internet won't work, and without a working ethernet I can't fetch the right drivers for anything.

I had also tried plain ubuntu 10.04 and couldn't get them to work then either. It said 'disconnected' at first, and then said 'device not ready' There is no hardware switch but there is a key toggle. It doesn't seem to matter what state the wireless was in before booting into Ubuntu Studio, so I'm lost as to where to even start. Even though the network manager isn't there like in regular ubuntu, I assume there will be a simple way to connect to the internet once the drivers are found, right?

I've seen issues and read about fixing them, but usually it uses an ethernet connection to fix the wifi connection and, being new to linux (<50 hours worth of experience lifetime), all I managed to do trying to fix it myself was screw up the installation to the point where the laptop couldn't access the home folder and I had to reinstall. Other than that, I am usually very good at following instructions, as long as they apply to my laptop's issue I guess

The only other issue is minor, I can't seem to control the USB mouse I have, but the trackpad works fine so it's no big deal, probably a matter of downloading the mouse driver once the internet works.

Currently I do have internet access via the same laptop while booting Windows 7 (I installed Ubuntu Studio 10.04 on a 10GB Partition with the idea of using an external HD for most data storage).

Oh and it is a 64-bit machine, the Studio version I installed is 32-bit.

Ubuntu Networking :: Broadcom BCM4312 Dell Studio - Built In Wireless Card - 'disabled' And No Longer Works

Jun 10, 2010

I recently installed Ubuntu x64 on my dell studio 1535 using the windows installer (wubi).

All seems to be working fine apart from the built in wireless card, the proprietary driver (found in hardware drivers) installs and activates successfully and works perfectly. Until I shut down or restart the system. On the next boot the wireless card is 'disabled' and no longer works.

The card I have is a Broadcom Corporation BCM4312 802.11b/g

I am going to try a proper install on a second partition rather than using wubi later on but wondered if this was a commonly occuring problem?

The wireless card works as soon as the driver installs, however I am shown a "restart to activate driver" message and after restarting it's dead.

Ubuntu :: Wireless Card Drivers On Dell Inspiron N7010

I had just installed Ubuntu in my brother's laptop and the drivers for the laptop`s wireless card got deleted, or that's what is leading me to believe. Prior to the installation, the laptop was picking up wireless signals just fine. I tried finding the drivers on the INTERNET but there are too many and I don't want to get the wrong one. Even so, I don't know how to install it through Ubuntu or anything. I tried the "disswrapping" app. but it was looking for some sort of ".if" file type. I also tried using the Terminal, but I'm not an expert on this kind of stuff. I got Ubuntu 2 days ago on my own laptop.
