Ubuntu Networking :: Card's Reconising A Eth Lead In But Wont Connect?
Dec 12, 2010
I could really do with some help here, been using Ubuntu for a long time now but a very slow learner. I use windows but only for gaming. The problem I have is, last night I had all my systems working fine (Ubuntu Server Edition 10.10 (used to be 10.04 and 8.04 and always work fine) and Ubuntu 10.10 and Windows XP duel booted on my desktop). All of this worked absolutly worked fine. Last night I needed to reinstall windows on to a seperate HDD and so decided to swap the HDD's in but server and desktop over and fresh install it all. after doing so I did and installed Server edition on the desktop before swapping over due to know screen or keyboard for the server) this is when I first notice that it would not connect to my network. During install it picked up the DHCP but once install no connection dispite ifconfig reconising eth0. so I put the new HDD's in and removed the server HDD and installed windows the ubuntu.. when I booted ubuntu 10.04 on live cd, it reconise the connection but would not connect at all, since then I have tryed putting in a PCI network card as well and comes with the same results. the odd thing is, untill the reinstall it all worked fine and dandy and never had any problems. I have not tryed windows yet as I need to install the drivers for that but I will do that now and post with a answer as soon as I know if it works.

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.

One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.

I have a lan card installed in my pc which connect to a dsl modem for broadband connection. some days ago I tried ubuntu 8.04 LTS. I tried sudo pppoeconf and just followed the steps and it easily got connected to internet. Then couple of days ago, I freshly installed ubuntu 10.10. But since then I havn't been able to connect to internet. I tried sudo pppoeconf and followed the same steps, but to no avail. When I tried ifconfig -v it gave me following output,
eth0
Link encap:Ethernet HWaddr 00:a1:b0:60:51:29

RX packets:197 errors:0 dropped:0 overruns:0 frame:0
[Code].....
I just can't connect. Like I said, I am really planning to scrap windows, but unless i can connect, this is not gonna happen.

I own a D-Link DI-604 wired router and I've started getting some issues after Ubuntu 9.10 to 10.04 upgrade(Ubuntu 9.04 used to work OK!). The problem is that Ubuntu recognizes all my ethernet cards (see below), but I can only connect to the internet through eth1 not eth0 (which is my Windows default). If I try to plug the cable in eth0 nothing happens (at least not in Ubuntu 10.04 and 9.10).
Code:
lucas@lucas-desktop:~$ sudo lshw -C network

I am using Linux Mint 9 Gnome: Isadora (since the same Network Manager applet is used in Ubuntu, I am asking the question here too)I was trying to configure my wireless card to connect my PPPoE connection by using the command pppoeconf wlan0 and also pppoeconf.I was not able to dial my PPPoE connection when connected via Wi-Fi. When I restarted my system, in the Network Manager, under Wireless Networks it says "Device not managed". Now I am not able to use my Wi-Fi card at all and cant connect to my Wi-Fi modem.
There is no hardware Wi-Fi switch, only the key combination Fn+F2 to enable or disable the wireless card.I have used the key combination Fn+F2 (which enables or disables the Wi-Fi card) many a times, but the same thing is displayed in the network manager.If I use LiveCD mode and use any distro even Isadora, the Wi-Fi works fine.My ethernet connection is working fine. I can connect to the internet if I connect my modem using Ethernet port.

Since my recent re-conversion into Ubuntu, I noticed Network-Manager now has mobile broadband support out of the box. Splendid!
I've been using my Huawei (Vodafone) modem since around two weeks, and so far it's been great, except for a little detail: sometimes, them modem simply won't work. I plug it in, "cd" drive (where the Vodafone Mobile Connect files are) shows up, but no "Vodafone" on Network-Manager.
I believe this has something to do with settings the modem may leave behind after each use, but I'm quite newb, so.

I've installed it no problems on my desktop and I really love it. Now I'm trying to install it on my Satellite and I'm having a couple of problems. When trying to connect to my wireless network, I can see my network, but it will just keep asking me for my WEP. I've confirmed that there is nothing wrong with the network or the password I've provided. Sometimes when I boot up, the network manager just says that the wireless networks are disconnected and can't find any. The wired connection always works just fine.
Here are the system specs:
Toshiba Satellite M45 S169
Ubuntu 10.04 Lucid Lynx LTS Fresh Install
Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)
Kernel driver in use: ath5k

I have an old Toshiba Satellite A30 Notepad. I've installed Ubuntu 10.04 onto it and everything but WiFi works. I've installed wicd and several other network tools but just can't get Ubuntu to let me use the WiFi connection (the option is greyed out).I know the card works because the last OS (Windows XP) used it without any problems. The card is detected, the drivers are installed and the hardware (slider) switch is set to on.I think the issue is related to the Radio Frequency Kill Switch being on but I don't know how to turn it off.The output from various commands are:
sudo lshw -C network is:

I upgraded Ubuntu to 11.04 I can NO longer connect wirelessly using my BCM4312 WLAN Card. It connected with no problems before dist upgrade using Ubuntu 10.04. Im really not sure why I cannot connect. I cannot even see my router in edit wireless connections settings. I can however see my neighbours routers who are using WPA2 encryption. But I cannot see my router.
I have uninstalled and reinstalled The Broadcom STA proprietry wireless driver several times using Additional drivers. This did not fix my issue.
I am connected by ethernet at the moment so I do have internet connection.

My ISP finished some 'upgrades' on its infrastructure. The result is that I am having great difficulty in connecting to the internet.
I have 3 operating systems on my box - XP, Fedora 8 and Feota 12.
I connect using an ethernet card, using dhcp. In fedora 12, the ethernet card is controlled be networkmanager. After the ISP completed their upgrades, I was not able to connect. I tried to connect manually using
Code:
There was an error message -
Code:
I read the advice here: [url], and removed all but the important lines.
But even after that neither ifup eth0 or dhclient eth0 works.
In fedora 8, the ethernet card is activated by ifup eth0 in /etc/rc.local. I was able to connect on a couple of occasions, but that too stopped working. I tried both ifup eth0, dhclient eth0, and tried to use the gui( which fires the dhclient command), but none worked.
When I use windows, it takes about 2 minutes to get an ip (earlier it was immediate). Sometimes that doesnt work and I have to click on "repair" whereupon it starts working.

I have a Dell Inspiron 1545 computer. I boot into Ubuntu with a flash drive. When I boot, I cannot connect to a wireless network. No available networks are displayed (and I know my router is on) and the Network Manager icon displays no bars. I suspect that the Dell Wireless card (having a Broadcom BCM-4312 chipset) needs a driver. I have tried to intstall both of the restricted drivers (BCM STA and 43xx drivers), but with no success. I have run lspci in Terminal, and got many lines of text. Here are the lines that look relevant to me:
Code: 09:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E Fast Ethernet Controller (rev 13) 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) In Windows 7, everything is just fine. In Ubuntu, my wired connection works like a charm, but is not really accessible. Basically, I have to connect to wireless in Ubuntu or I have no reason for having it.

After installing Lucid, I noticed that my Ralink RT2860 card would not connect to my home network using WPA2 despite the network being visible and of good strength. So I followed the guide at [url] in order to install the newest Ralink drivers.
After installation, same issue. That is, the card will connect to my a/b/g/n network if I leave it unprotected, but it will not connect to the same network if switch it to WPA2. After being given the passphrase, the wireless icon on the indicator applet shows that it is trying to connect, but after awhile it fails. Does anyone know why the built-in driver and also the official Ralink driver are no good for WPA2 in Ubuntu 10.4 for my RT2860 card?

I'm not exactly sure if this should be here and not in the Hardware & Laptops section, but seeing as my only problem is with WiFi, I'm guessing this is the right place. Under Ubuntu, my laptop (an Asus K42Ja, more details below) can see wireless networks normally. However, when I attempt to connect, it fails to establish a connection. Under Windows on the same laptop (dual boot), no problems are experienced.
According to this, there's a firmware bug in my wireless chip which causes connections to get dropped. I'm not getting connections at all, but I still tried the workarounds on that page with no luck. The router is a TP-Link TL-WR340G. My previous laptop, a really old one from 2003 running Ubuntu 9.10 was able to connect to that router without problems. The wireless card was Intel on that as well (but, of course, much older). The router is set up to use WPA for security. I didn't use WPA2 as I read something a while ago about problems with WPA2 and some Linux distros. Please correct me if I'm wrong here.
If anyone's curious, I'm posting this on Ubuntu, via an ethernet cable to the router mentioned earlier. Some tasty technical bits: dmesg (the latter half of the "timed out" messages is me retrying after double-checking the WPA key)

The Network card sees the Wireless network, but will not connect to the router. I have tried with and without security, and neither setting makes any difference. Using the Wired Network adapter does work when set to a STATIC IP.

I just installed 9.10 and I can't detect any wireless networks. Is the card compatible with 9.10? Do I need to install any drivers? If the card isn't compatible with 9.10 is it compatible with later versions of Ubuntu? Marking this as somewhat urgent as I need to get internet access for some coursework soon, and also because my parents will kill me if they find out I've done anything unusual with the laptop because it's new and they think anything non -MS is a virus.

I'm setting up my first Linux laptop with Ubuntu 11.04 and my CB21ag wireless card works, but won't achieve speeds over 11Mbps (maybe not "doing 802.11g rates for some reason?) I guess this cardbus card is manufactured by Atheros for Cisco so I maybe that's why I'm seeing two wireless connections - the one with the "airo" driver gives me 11mbps, the other with the ATH driver would only get me 1mbps so I deleted that. The card seems to disconnect/reconnect periodically too - messages pop up frmo the wireless icon ...
lsmod says "airo" and "ath5k" are loaded
So to get 54Mbps (802.11g speed) I'm wondering if theres maybe a different driver module for the CB21ag card or some configuration I need to tweak. More info - security is static WEP, lshw -C network returns some "wierdness" about network 0 ?
-laptop:~$ lshw -C network

Running Linux mint 10 After the installation the wireless connection worked but it was very weak and intermittent. The icon would show 1 bar or none. iwconfig showed the rate at 1Mb/s. The same card worked fine in windows and on a 32bit version of linux. Installed new driver from realtek. Now the iwconfig readings look good and the icons shows 2 and sometimes 3 bars. But it will not connect at all! I even turned off all security on my router but it would not connect.

I'm using ubuntu karmic and I'm not able to connect to the internet with my reliance netconnect data card using network manager. Other distros like fedora, opensuse n sabayon connected easily with nm. Ubuntu detects the data card flawlessly but just doesnt connect.This problem has been persistent even in previous ubuntu versions, n I used to use wvdial. But downloading wvdial on some other comp with every dependency is really cumbersome.

Does anyone have a suggestion for a very simple tool I could use to manage sales leads?
I said CRM in the title of this thread, but I don't really need anything that full-featured. All I want is something to help me manage my job search by keeping track of which jobs I have applied for, when I need to phone particular agencies again, and that sort of thing. I have tried installing a couple of Apache-based apps, but they have turned out to be too complicated to set up. I couldn't find a desktop app in the repos, but maybe I have missed something. A cloud-hosted service would probably be OK, so long as it is within my current �0 budget.

wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.
