Ubuntu Networking :: No Ethernet Nor Wireless With 11.04
Jul 13, 2011
i'm a beginner with ubuntu and i installed 11.04 yesterday (so not yet familiar with the new desktop configuration). Also, I have the french version so i'll do my best to translate the terms in english. I have a major problem: i can't connect to internet by ethernet cable or by wireless. The network icon is always empty. It doesn't detect the ethernet cable and the wireless networks around. I've tried different things i found on forums. I'v reinstalled the b43 package and rebooted. At the beginning i was only having problem with the wireless; i could connect via ethernet. But on one forum, a dude suggested the command

I have been using Ubuntu for quite a while now (~3 years.) I recently installed 10.10 on an HP Mini 1000. The installation went fine, but now I am puzzling over how to connect to the internet. When I plug an ethernet cable into the netbook, the port light lights up, but the system does absolutely nothing. Under the connections menu on the top panel, it just says disconnected. Also, the wireless connection section states that the device is not ready because firmware is not installed. Most solutions I see for problems of this kind are to download the drivers, but I cannot do that because neither connection works.

I just upgraded to 10.04. I had wireless connection for 1 day and now nothing. No ethernet connection either. I CAN use both wireless and ethernet using my machine on Windows.....so the connection stuff does work. Here's the output of of the commands I got from the "sticky". I can't display the output as this forum puts it all together as one continuous sentence with no line break!

I have a Toshiba Satellite L645D-S4030 running on Ubuntu 10.04. When I plug an ethernet cable into the ethernet port, simply nothing happens, and when I try to connect to my wireless network, it connects but there is no actual internet available. I'm sure the wireless works as I'm on an older model Toshiba Satellite and it connects fine (running Ubuntu 10.04 as well.) I tried to follow the procedure in the stickied thread, so when I type in these commands, here's what shows up:
Lspci
00:00.0 Host bridge: Advanced Micro Devices [AMD] RS780 Host Bridge Alternate
00:01.0 PCI bridge: Toshiba America Info Systems Device 9602
00:04.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 0)

have used f14 since it came out with no problems, little niggles and whatnot have been sorted by reading these forums and googling but I'm now out of my depth.problems started when I installed f15 from disc and no ethernet or wireless was useable. Inserting wire leads to it announcing it's unplugged again a few mins later and trying to connect wireless never resolves.I thought it was a quirk and would go back to f14 for a few weeks but after re-installing that was now the same. So I tried live discs of crunchbang and debian6 -same. However puppy linux sees the ethernet fine.So my question is how do I enable ethernet and/or wireless in f15 (installed again after checking with puppy)?

I just installed Ubuntu 9.10 on my HP dv6500, and neither the wireless won't work. I don't see any drivers under System >> Administration >> Hardware Drivers, and I can't connect it to the internet any other way when I'm running Ubuntu. (I still have Vista as a dual-boot, and it works fine there). (Sorry about the title - the ethernet DOES actually work, but I can't seem to change the title of the post).

I'm trying to share my ethernet via my wireless card. It doesn't work. Here is some info:
lspci
04:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
lsmod
b43, mac80211, cfg80211, ssb
I've tried everything listed in these forums but every time I run
sudo iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
I tried the STA drivers and get the same thing except the kernel module loaded is wl instead of b43. Is it even possible to set this card to master mode? I can't find jack on the net.

I have a Dell Studio 1501 Laptop and I want to bridge the wireless with the ethernet port so I can hook my xbox360 to my laptop.
I've spent the last 2 hours trying different techniques but nothing is working.
I'm running Ubuntu 9.10 so the last thing I tried was going into the network manager, clicking on wired, editing the ethernet port and allowing it to share. This did nothing.
I tried to share the connect with firestarter but that did not work either.

I tried to setup a connection as below but face some problem (probably route table setting incorrect). Hope if anyone could shed the light.Basically, I have a PC1 (.1) and PC2 (.130) connected via a PC router. PC router has 2 interfaces: wireless (.2) and ethernet (.129). PC1 connects to PC router via LAN cable/wireless interface, while PC2 connects to PC router via cable. This settings try to simulate 1 wireless connection along the path (and because PC2 is too old to support wireless interface, we need a PC router). These interfaces are all under same 172.16.130.x subnet.

I am running Ubuntu 10.10
I am using an Intel WiFi Link 4965AGN built in adapter.
When I was prompted for a system-update I clicked Update and apparently something failed an only a partial-update happened. Now my wireless/Ethernet connections do not work. I tried enabling all Network Adapters but that option is no longer available in the "Preference/Administration" tab.
Note: I cannot access the internet at all on that partition so I can't download any updates from repositories.

My wireless works flawlessly (aside from my generally crappy signal ahaha), but when I decided to do a minimal Ubuntu live install on my netbook [Asus Eee 1005PE] (I tried both 10.04 and 10.10 with the same results), it wouldn't pick up my ethernet.
I decided just to load up my existing OS (Ubuntu 10.04 32-Bit) and got the same thing.
The wireless, as stated before, works without a problem, and it's weird, because the wireless manager says that knows the ethernet connection is there, but it won't connect to it...
[Edit: I did play around with different combinations in the BIOS (ie: lan enabled, wlan disabled, ect...)

I tried to setup sharing to connect Ethernet and wireless. I want Ethernet connected to desktop A, and wireless connected to another laptop(B), with my laptop acting as an AP. I set the network settings in Firestarter: Internet for wireless, local network for Ethernet. I want to share Internet from laptop B over the network. Internet won't work from my laptop since it seems to use the wrong interface.(Since the desktop is sharing Internet, although not on Internet usually when connected via Ethernet. And of course DNS/Gateway IPs aren't set for wlan0 since it's acting as an AP.) SMB wouldn't work for desktop A and laptop B: laptop B could detect desktop, but reports error "Path not found".

I'm been wanting to try Ubuntu for a while now, and when my mom's netbook started to get insanely slow with WinXP, I tried the Netbook Remix on a USB stick. I LOVE it, except I am unable to get the wireless working, which is the only thing stopping me right now from a full install.
I believe my problem is that I need to activate the two drivers "Broadcom B43 wireless driver" and "Broadcom STA wireless driver" which appear as unactivated when I go into the hardware drivers admin tools. Unfortunately this netbook (HP Mini Netbook FW376UA) does not have an Ethernet port, so I can't just temporarily hard wire it to activate these drivers.
So my main questions are: 1) How can I activate those drivers without an internet connection?, and 2) Do you think that activating these drivers is indeed the answer to getting the wireless working?
The details:
Machine: HP Mini Netbook FW376UA
Network Controller: Broadcom Corporation BCM4312 802.11b/g
Ubuntu version: Ubuntu 10.04 Netbook

I absolutely love Lubuntu on VirtualBox. I installed it to my Compaq Mini CQ-10 without issue. However, there are no drivers for the Wireless or the NIC. Ok, so I go to Broadcom and download the drivers. But, when I try to install with the Makefile, Terminal tells me that make is not installed! Now, how do I install my drivers without make?

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:

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)

I have a Dell Inspiron E1505, which has the Dell Wireless 1505 (Broadcom) card. To run the card, I installed the Broadcom STA wireless driver, which seems to activate the wireless card OK. The problem is that once I installed that driver my onboard Ethernet card was deactivated (and yes, it is enabled in BIOS). I had to remove the wireless driver to get the Ethernet back. Does anyone have ideas? I haven't found this problem listed elsewhere. I am running Ubuntu 9.04 with no other problems.

I'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.
Here's some of my specs if that's of any help:
Computer is a Sony Vaio laptop model VGN-SZ370P
My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller
The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...

When I select the wifi icon on the panel, it just shows "No network devices available". I know my network can be found when I search with my iPhone, so I know there are networks to connect to. So, I checked the drivers, and it informs me that the B43 and STA drivers are not activated. So thats not a big deal, I guess, but when I use my ethernet cord, my laptop doesn't recognize/acknowledge (I'm not sure what the right term would be)it. I'm fairly sure I can't activate these drivers without an internet connection because when I do try, a message pops up saying "failed to fetch" with some long link.
My only guess is that it could be a hardware problem, but I really have no idea. I guess the ethernet problem is my only real problem. Because after I establish and internet connection the the rest is easy to fix.I'm sure its obvious, but I'll go ahead say that I'm a novice ubuntu user. I've only been working with it for about a week, but I'm learning alot.

I have one of these nifty Atom based "net-top" boxes that has built in wireless N and gigabit ethernet. the problem I have is that even when the ethernet cable is plugged in Ubuntu seems to be defaulting to use the wireless connection. This is a problem since in some areas of the house where I have a wired connection the wireless signal is pretty weak and so the ethernet traffic becomes spotty.
is there a setting somewhere where I can force ubuntu to prefer the wired over wireless no matter what, or to disable the wireless when the ethernet is plugged in?

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.

I have two motherboards, MSI-6702 (64 bit single channel) and MSI-7511 (64 bit dual channel), I have two identical D-Link wireless cards and am running Kubuntu 10.10 on both systems. 7511 recognizes both wireless cards and connects to the Internet.The 6702 shows wireless grayed out on the connections page. The built-in Ethernet card has given out on both. I think I disabled it on the first system to have an Ethernet problem and wonder if I need to do it on the second. I would have tried it already but can' t remember how.

Using ubuntu 10.10 (pinguy OS) i connected an ethernet cable from my girl's macbook pro to her lenovo ideapad s10-3t to transfer some DS9 episodes onto it. new enough to linux to have not been able to figure out how to access the files on the mac, so i disconnected the ethernet, and the wireless hasn't worked since. tried everything i know, and googling for a while (as well as searching again on this forum) to no avail.
Just before linking the 2 computers via ethernet, the wireless worked fine on the ideapad, always had; but not so after the ethernet connection that did nothing other than apparently kill the wireless. an "lshw -C network" command tells me i have a BCM4313 wireless card, and *-network UNCLAIMED. also, if i launch "install additional drivers", i see that the proprietary driver is not active.
How could merely plugging in an ethernet cable that happened to be conncected to a MBP running OSX.6 do that? and will that happen again? i thought linux was supposed to play real nice with other OS's, so why did a simple file transfer kill my wireless connectivity? i have no access to internet via ethernet cable, so i cannot just download the driver i need now. shouldn't it still be in the computer still? somewhere? is there a simple solution to this, or has the wireless driver been wiped out by plugging in the ethernet? is this a bug that should be reported?

Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.
