Ubuntu Networking :: Wireless Works - Wired Doesn't ?
Jan 31, 2010
I recently got a cable modem from Comcast, and connected a Belkin F5D7230-4 wireless router to it, then connected my computer and an Xbox 360 to the router with ethernet cables.
My computer dual-boots Ubuntu 9.10 and Windows 7. In either operating system, the wireless connection is flawless. In Windows, so is the wired connection. But in Ubuntu, there's a lot of trouble with the wired connection -- specifically, while I can connect to the router and to the Internet, and while I can use ping, dig, traceroute, etc., to verify connections to remote hosts, Web browsing, or anything else that uses http, works only for a few Websites, and then only erratically.
I don't believe it is a DNS problem -- testing with ping, dig, etc., demonstrates that, and I have also tried using alternate nameservers. I also don't believe that it is an issue with IPv6, as I've tried the fixes usually suggested, including editing the grub configuration to disable IPv6 support in the kernel and verifying that IPv6 was inactive. I've also tried using local dns servers such as pdns-recursor. None of these things seemed to help.
Also, perhaps unrelated, but disturbing: my computer has locked up a few times while testing the wired connection, and I had to use a hard reset to restart the computer.
I have recently bought a new laptop for this purpose. It is a Toshiba L555D-103. It was pre installed with Windows 7 (64 bit). I have now installed Ubuntu 9.10 (32 bit). It works perfectly when wired. But it does not when I try it wireless. It did work wirelessly with Windows 7, and I have many more both stationary and laptops working through the router, so I do not think the router is the problem.I am guessing that there are no drivers for the wireless to function, but I am not sure. I am guessing that there are no drivers for the Ethernet card ?
As of now, my internet works fine when connected with an ethernet cable.The problem is it doesnt seem like my wireless is working at all.The led light is orange, (its usually blue when it connects) and I cannot see my home dsl network.Is thereany specific troubleshooting steps I should take?HP dv6000 laptopwireless card: Broadcom Corporation BCM4311 802.11b/g WLAN
I've recently installed KDE 4.4.1 just to try on a Dell 1545 laptop with Ubuntu 9.10 previously installed.
My problem is that the wireless connection works just perfectly with nm-applet under Gnome, but when I login on KDE and ask KNetworkManager to connect to the same network as before, it can't finish the connection.
When I choose the connection the program asks for my passphrase, I type it and then it just sticks on "activating network" and nothing happens.
My experience with KDE is zero, so I don't even know where to start looking. I'd even tried to kill KNetworkManager and try to replace it with nm-applet, but I think there's a daemon that restarts it immediately.
Ubuntu 9.04 with working wlan. I had to restart router & wap. It doesn't seem to ever retry to connect. I know my router & wap are good, I have wireless working on other laptop (running Puppy) I had to go into 'edit connections' in drop down and use 'wireless' tab then edit 'wireless connection 1' and hit 'apply' is there a better way to do this? also, no connections show up with command 'iwconfig' edit: with ifconfig, eth1 si showing data my ip address and packets sent & rcvd. I think I'll try do duplicate this event and use 'ifconfig eth1 down' and then up again to see if it reconnects.
opensuse 10.4 KDE. wired internet works but the network manager is dead, there's a red network icon with a cross in the panel and opening the manage connections window only the VPN tab works all others are grayed out cant setup any wireless or mobile broadband connection. on the live cd there was no problem with network management.
I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.
However a pint to that ip address (my router) is successful.
Hosts.allow and hosts.deny are both fine (not blank but no entries)
It's been a while since i've been trying to deal with this problem but it was useless. I've found many related problems to this, most unsolved and those who had solution wouldn't work for me. I have few mates who have the same problem and still didn't find a solution as well. Here's the problem:
Both on my Desktop and Laptop, the network manager won't recognize that there is a cable pluged on the computer so that it would start my connection. The solution to make it work is pretty simple and its everywhere: use pppoeconf.
Altough that does the trick to make my internet work, i get another problem that i found out to be related to this one, which is: I can't use VPN. Which make me assume that one problem is related to the other, is that on my laptop, which has wireless internet, ubuntu will recognize it and then i can simple use vpn. My desktop, on the other hand, isn't that lucky and does not have wireless, so i can't just use vpn. So far, i've been using vpn on windows when needed, but switching systems is really a pain, not to say i'd rather do that on ubuntu.
Few other suggested solutions were to use 'wicd' and other network managers, altough for some people that did work accoding to what i saw on boards, that didn't really work out for me as well. Wicd coldn't recognize it either. Other suggestion was to check on some txt file on ubuntu, erase few information and let it 'fill up' automatic, it didn't work as well(sorry i don't remember all details on this one).
This problem happened on: First, wubi for ubuntu 9.04 Ubuntu 9.04(normal install.) Ubuntu 9.10 Happened both on my Desktop and my notebook, but the same version i installed on both of them were used on other computers and they did work on them so i strongly believe it has to do with the os itself.
I recently re installed everything so I could dual boot. Well my wireless on my Ubuntu works but my wireless on my windows doesn't. I used my Toshiba recovery to re install some of the programs like Intel proset(wireless program) well it finds my router and everything but the connection is limited. When I click repair it doesn't work and proset finds my ip addresses but i don't know why it doesn't connect.
I used the "Upgrade" option the last couple of nights to go from 8.04 LTS and was going to go to latest version. Well got the upgrade done last night on 9.10 and now Broadcom gigabit wired connect will not connect to internet. Can ping router just fine. Just cannot get outside of it. Shows as configuredin ifconfig. But the name of it under the network manager is odd. Its ifupdown (eth0) (default) and maps to ent1.
It has been a while and many ubuntu updates since i connected the windows laptop, it used to work fine but this ubuntu machine keeps telling me the cable is unplugged. When i boot into windows XP the network works fine and the laptop can connect through the network to use the internet. I have a very simple home network ... 3 pc into one switch. I am by no stretch of the imagination good with networking
The problem I have is when I install 10.10 I get no wired connection my wifi works great, just no wired connection. I don't have WiFi where I am right now. It works fine when I run off the dvd , but when I install it i get nothing. I have tried static ip, reinstalling, reinstalling drivers. Don't know what else to do. I have a Dell Inspiron 1720. The ethernet is a broadcom 440x.
My wired internet was working fine and dandy under Maverick until today. For no apparent reason, it stopped. The router works fine. All other computers are able to connect. I've tried using different cables with no luck. I have a Biostar A785G3 motherboard with an integrated Realtek RTL8111DL ethernet controller.
My problem sounds very similar to this guy's: [url]. But his strange solution didn't seem to work in my case.
I bought a switch, connected it to our router,and moved the patch cords to the switch. All but one of the workstations connect & work fine. If I plug the non-connecting wire into my laptop it connects. If I plug the non-connecting wire back into the router,the workstation connects.So...it seems that this particular workstation will only see the address of the old router. It's stuck in there & won't refresh. Two of the PC's & the laptop are running 10.04 (Mint 9 Actually), and one has Windows XP on it.e problem is with one of the 3 10.04 boxesI have tried removing the power cord & MB battery and leaving them out over night.Also cleared the bios. Same results. Connects fine to the old router but will not connect to the new switch.
I recently tried out OpenDNS on my wired connection, however after it was slower than faster, I tried going back to the original settings that the connection had (so basically to Automatic DHCP).
For some reason the connection wouldn't connect again. So I thought I'd try deleting that connection and creating a new one, but this still doesn't work. When I try to connect using NetworkManager it just does the 'loading' icon for 30ish seconds then says disconnected.
My wireless still works fine however.
I'd very grateful as i'm worried i've messed up the ethernet port and I need it for when I got University in a couple of weeks
what is the command to restart the network services? ive forgotten i think it uses -hup switch though. about 1 in 20 boots on my desktop ubuntu system results in the system insisting its no longer on a network yet has a fully functioning network card. a reboot always fixes the issue but that doesnt seem like a long term solution to me. If I ping a neighbouring system I get nothing. (sent packet count increases in ifconfig) If I ping from a neighbouring system back to my desktop I get nothing (no change in packet count) I can bring down and back up the network interface with no results. A sniffer shows the system definitely isnt sending anything out Everything worked previous boot and will work again after a reboot.
Using 10.10 and have a wired connection that according to the system is connected, but when I open a browser I can't connect to any sites. What am I missing here? I can't for the life of me figure this out.
These days I wanted to connect to the internet on my laptop using a wired connection. When I inserted the ethernet cable, I was surprised to see that it doesn't work on Ubuntu 11.04. So I decided to boot into Windows and see if it works or not. And I found that it works without problems on Windows.
My desktop PC has 2 NICs. I have Ubuntu on it since several years, and I remember that both eth0 and eth1 used to work. However, I discovered recently that currently only eth0 works, and eth1 is dead, but I don't know why. It's been a while since I've tried eth1, so I have no idea when exactly it broke. I suspect the problem may be related to the fact that the MAC address is incorrect: it is set to 00:00:00:00:00:00, which seems wrong. But I have no idea how this happened...Any idea what might be wrong and how I can fix it? Here is some output which I think is useful:
Code: peter@cheetah:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr 00:18:f3:68:42:78
I have installed Ubuntu 11.04 using Wubi through Windows 7. It seems to be working but it will not connect to my wired internet connection. It tells me there is no wired connection, when there is. I used sysinfo and its not showing any network adapter or controller. I have a board with nvidia nforce go 430, could it be a driver issue. It works fine in windows though. Tried using a wireless adapter and all is working. But why doesn't the wired ethernet connection work.
one of these "WiFi works in Gnome, not in KDE" threads, but I have been all over google and hundreds of threads across different sites and can't figure this one out.As mentioned, wireless is peachy in Gnome, unfortunately I like KDE and I'm more productive using it (when I have internet). Wired network works fine in KDE, and my network card
I've got Puppy Linux on a USB key, and yesterday, while I was on the internet with it, it hanged. I didn't know what to do, and I rebooted from the button (I now know what to do ). The problem is that, after rebooting, Puppy doesn't recognise the router. I've tried to apply the drivers that are on Puppy, but there aren't any compatible.
My router is a Xavi 7968 and my Network Card is:
NIC Fast Ethernet PCI Familia RTL 8139 from Realtek
(On Realtek's website, there isn't any driver linux-compatible)
I got a problem about network proxy setting. With the graphics setting interface, I set auto proxy with the URL address but it is weird that the setting only work with eth1(wireless), doesn't work with etho(wired). however my wireless driver is always a problem for Linux. i also tried export http_proxy= XXXXX:8080 it still doesn't work at all.
I have Ubuntu 9.10 installed on a VM Server 2.02 with a Win7 32 bit host. When the host is wired into my network, the Guest (Ubuntu) has internet conductivity. However when the host is connected via Wireless, the Guest Does not have any internet connectivity. The VM Network connection is set to Bridged.
in short : installed 9.10 on a dell inspiron 600m which has a broadcom bcm4401 ethernet and an intel PRO/Wireless LAN 2100 3B mini PCI. At this point, i'm not too picky about which one works (meaning neither of them currently work). nm-tool seems to pick up on both : the broadcom (eth0) is using the b44 driver, State is unavailable; the intel (eth1) is using the ipw2100 driver, it's State is disconnected.
i have encryption turned off, and the wireless sees a number of AP's (including mine).
i'm jumping off the good ship m$ and determined to make this work!
I just did a fresh install of ubuntu studio 10.04 and I can not connect to either a wired or wireless network. The In Network Tools the IPv4 IP address is 127.0.0.1. It is plugged into a network giving out DHCP IP's. Both wired and wireless were working on ubuntu 9. I have tried to bring eth0 up in the terminal but it did not give an error or anything. It it running on a Dell Latitude D820 laptop.
