Ubuntu Networking :: Bizarre Wired Network - Download Updates And Firefox

Jun 3, 2010

I have a dual-boot Compaq CQ60-420US laptop. It can connect wirelessly in Vista without a problem. I have not yet figured out how to connect it wirelessly in Ubuntu (10.04, Lucid), but that's not the problem here. The problem here is on the wired side. Whether I boot in Vista or Ubuntu, I cannot get it to go online. Ubuntu says that the Auto eth2 connection is established; I am able to disconnect and reconnect it normally; but I can't download updates and Firefox can't connect to CNN.com. Likewise, in Vista, diagnostics find no problem; everything seems to be fine; but no connection.

I thought the problem might be the laptop's ethernet port, so I bought a Trendnet TU2-ET100 USB-to-Ethernet adapter. It comes highly recommended; it seems to have installed successfully in Vista; it appears properly in Vista's Network Connections; its lights are blinking appropriately; and Ubuntu tells me that my Auto eth2 connection is established when I connect through that adapter. And yet still no connection to CNN.com and no downloads of updates in either OS.

I wondered if some other circuitry might be at issue, so I sent the laptop back to HP. They claim to have replaced the mobo. The symptoms remain unchanged before and after. I went through an extensive tech support call with HP. The last thing their technician could advise was to power cycle the laptop and router. The ethernet connection itself is good. I can unplug the cable from the laptop's ethernet port or the Trendnet unit, plug it into the desktop computer on which I am typing this note, and I'm connected with no problem.

I thought, well, maybe I have to have the laptop's wireless button on, even when I want to connect via wire, but that hasn't made a difference. I tried installing Windows drivers from the Trendnet website instead of from the CD; no joy. I suspect you will be as stumped as I am. I have gone through a lot of other people's comments. At this point, I am just interested in general possibilities. What, in theory, could be causing this?

Ubuntu Networking :: 10.04 Server Not Connecting To Internet (Wired Network)

Jun 10, 2010

I just installed Ubuntu server edition on to an old Dell desktop. The only problem is that I can't get the Internet to work. I have tried the following and I guess it doesn't work:

Code:
sudo ifconfig eth0 192.168.1.52/24 up
sudo route add default gw 192.168.1.1

Each of those commands don't give me any error and it would seem like everything works fine, until I try to ping google or any website and I get an error that tells me that no host was found. I am using version 10.04 of Ubuntu server.

Ubuntu Networking :: Wired Network - Can't Get The IP From Dhcp Server (TW-EA510) And Static Settings Doesn't Work

Feb 16, 2011

I'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.

Log from the router after issuing #"dhclient":
Feb 16 23:01:43 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0
Feb 16 23:01:43 DHCP SERVER: DHCP offer to 00:01:29:fb:c5:d1
Feb 16 23:01:49 DHCP SERVER: DHCP request from 00:1b:ea:c8:a0:ba

Feb 16 23:02:03 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0
[Code]....

Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.

Ubuntu Networking :: Cannot Obtain IP Address On Wired Connection

Jan 30, 2010

I am having a persistent problem with getting a wired network connection under a recent install of Ubuntu 9.10. The network manager will show the wired network as 'disconnected' after a restart. This is true whether I am connected directly to my ISP's modem, or through the Linksys router that I usually use.The output of ifconfig suggests that eth0 is not being assigned an IP address:Code:I have reached the limits of my own ingenuity.

Ubuntu Networking :: Lost Internet Connection - Firefox Displays Server Not Found Page

Apr 6, 2011

I have been using ubuntu netbook 10.10 on my Dell Mini 9 for the past few month without any problem; it connects wirelessly to the internet via a wireless router. Yesterday in the middle of web surfing, suddently firefox cannot see any website outside of my home network (Firefox displays Server not found page). No help when I rebooted a few times and connect to my home network via wireless or even wire cable; it can access files in my network file server (DNS-321) but not the internet. My desktop computer running Windows Vista and ASUS media player has no problem accessing the internet.

WICD 1.7.0. hangs on "wired connection: obtaining ip address...". I have downgraded to 1.6.2 and 1.5.9, but this did not solve the issue.

Fedora Networking :: No IP Address From DHCP Server On Wireless Network?

Feb 12, 2009

I have installed Fedora 10 on my A860 Dell Vostrol Laptop with AR242X Atheros Wireless card. Wireless card worked out of the box and i could detect wireless network and connect to it. But i have a problem that, my wireless connection is not able to get IP address from the DHCP server. Please help me out what can i do to get this working. I am using WEP security and authentication is open system.

I have windows 7 beta installed on the same machine and on that wireless network works fine so i am sure that there is no problem with the wirless network. I am using DIR-300 router from D-LINK. I tried to see packet log on wireshark and there i see that there is no reply to the DHCP discover message. Actually i don't see any RX packets at all. Which is not normal as there is traffic on the network.

OpenSUSE Network :: Wireless Card Realtek 8187 Connectivity - (Firefox) "the Server Can't Be Found"

Dec 3, 2009

I have a Toshiba Satellite L305-SP6944C, Pentium Dual Core 2.16, 2GB RAM, 160GB hard drive, DVD-RAM UJ880AS, display 15.6 TFT widescreen, ethernet Realtek RTL8101E/RTL8102E PCI Express, WLAN Realtek RLT8187, Opensuse 11.2 and KDE 4.3.1. Installation was OK and finally the wireless card is working... but I don't have conectivity bacause in the browser (Firefox) appears a message saying "the server can't be found"

I follow the howto write by Swerdna. With ndiswrapper I install the XP driver for RLT8187, KnetworkManager is in charge of connections showing both eth0 and wlan0, the wireless sign of router Dlink DIR-280 is OK, in the dialog box of network connection I put the mac address of the wlan card but I think that is not the problem.

Other thing that I missed is that I don't find boot.ini at any directory to add modprobe ndiswrapper in the boot sequence, in etc/init.d/ appears a "boot" file, is this file that I have to change to modprobe ndiswrapper??

Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting

Dec 16, 2010

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.

So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.

My files are as follows:

Debian Configuration :: Stop Squeeze Auto Using My Mobile As Wired Network?

May 25, 2010

I have Debian Squeeze AMD64 bit release. It finds my wired ethernet connection and ues itfine, although nothing shows up in the top right corner under the networking icon.

When I plug my mobile phone in (HTC S620) it always uses this as the main internet connection and then even if disconnected wont use my wired connection until I reboot.

Is there a way to stop it doing this or at least have my wired connction as an option so I can just click to reconnect to my ethernet connection?

Debian Configuration :: WiFi Connection Stuck At (Setting Network Address)

Ubuntu Networking :: Wired Network - You Are Now Disconnected

Jun 12, 2011

I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.

I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:

Code:
Wired Network: You are now disconnected
I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.

Networking :: Configuring Wired Network Ubuntu 10.04?

Feb 16, 2011

"Need help with entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. I will appreciate some step-by-step instruction or example of how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop." I have repeated what I tried in the ubuntu forum without success. I'm really in newbie category, and not comfortable with computer or internet jargon. I can still connect with ubuntu 8.04 and firefox, just once daily. In a later post I also added: In Ubuntu 8.04 there was a system> admin> network tab (missing in 10.04). In the connections tab "wired" was checked. The general tab had my computer name (tsq-laptop) for host, and a blank box for domain name. The DNS tab had 192.168.1.1 in the servers box (presumably my service provider BSNL), and nothing in search domains. The hosts tab had a list of IP addresses and aliases, the first few being:

127.0.0.1 - local host
127.0.1.1 - tsq-laptop
::1 - ip6 local host ip6 loopback
fe00:: - ip6 localnet, .... (and a few more such I think most (or all) of these entries were generated automatically by the system, since I don't understand the jargon at all! I don't recall having any difficulties then, some two years back.Before that I had major problems in using the internal modem for a dial-up connection, but got detailed help by e-mail/internet from some really knowledgeable people in Europe and elsewhere regarding linmodem configuration, which I followed blindly and it worked!
In 10.04 there is only the taskbar icon to edit settings, and it has a different structure. It asks for MAC address (example 00.11.22.33.44.55). Other info required is IPv4 settings, DHCP client ID, about routers and other stuff. There may be other system settings to be made, which I can try with proper guidance. The ubuntu help page gives very sketchy information, and the images are not clear at all. No response to that till second day. Subsequently: In the 'wired' tab the 'routes' button popped a table where I entered address as 127.0.0.1, and netmask as 255.0.0.0, leaving gateway and metric blank. This is all geek stuff for me - I'm an old-fashioned engineer from the slide-rule era!

Should all this have been in the newbie forum? Thanks, =TeeSquare=
