Ubuntu Networking :: Wired NIC Doesn't See New Router?

Oct 16, 2010

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.

Ubuntu Networking :: Can't Connect To Wired Router?

Oct 23, 2010

I wanted to try Ubuntu again but have gone wayback to an old 8.10 disk because I couldn't get 10.10 to work. The install with 8.10 went fine but the internet will not connect. The network manager shows eth0 grayed out and when going in to manage the connection it says 'never'. I'm using Vista with a broadband modem connected to a netgear router.

Networking :: Set Up A Wired/wireless Router

May 11, 2011

I'm trying to set up a wired/wireless linux router. it wirelessly connects to a network, then is wired to the internet port on my netgear wgr614.

eth0 (wireless) is dhcp

eth1 (wired)

The router

Internet port is static

And local network

I turned forwarding on, set the iptables for masquerade and nat, but i'm not really sure what i'm doing wrong. any pc connected to the wrg614 can see the pc thats supposed to be forwarding packets but can't see any further(the other router at 192.168.1.1 or the internet).

Ubuntu Networking :: Can't Connect To Router Via Wired Connection?

Jun 24, 2011

I have installed Ubuntu for the first time (version 11.04), finally making the step to open source software. Everything seems to be working fine, however I can't connect to my router via a wired connection.I can use the wireless network,hich was detected and I could connect by giving the code. But when I try to connect to this network by wired network, it tries to connect and it says "connection offline" after a while. It never establishes a connection. I used the standard automatic DHCP settings of eth0. I never got this problem with another OS and it's not the cable that's not working

Ubuntu Networking :: Intermittent Connectivity - Wired Router (WRT54g2)

Nov 10, 2010

To be brief, I am having intermittent connectivity issues with a wired connection to a WRT54G2 router. I have no such issues if I am plugged straight into the modem. My wireless persists throughout the outages and they usually require me to restart the interface on my machine. I have used Wicd Network Manager and Ubuntu's out-of-the-box Network Manager.

hostname -rs

ifconfig eth0 .....

Ubuntu Networking :: Wired Ethernet Connection - Unable To Connect To The Internet Or My Router

Dec 5, 2010

I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.

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.

Ubuntu Networking :: Wired Connection Doesn't Work / Get That?

Sep 18, 2010

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

Ubuntu Networking :: Wired Network Sometimes Doesn't Work

Feb 14, 2011

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.

Ubuntu Networking :: Wired Connection Doesn't Work / Fix This?

Jul 6, 2011

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.

Ubuntu Networking :: Wired Network Doesn't Work (HWaddr 00:00:00:00:00:00)?

Dec 6, 2010

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

Ubuntu Networking :: Doesn't The Wired Ethernet Connection Work

Jul 25, 2011

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.

Networking :: Puppy Doesn't Detect Wired Ethernet?

Jul 2, 2011

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)

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

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.

Networking :: Router Doesn't Support IPv6?

Networking :: Iptables - Forwarding On Router Doesn't Appear To Be Working

Sep 12, 2009

For the background, I'll be using my router as a firewall with snort-inline enabled. I got 3 NIC's: one for the WAN, the second will be bridged to the WAN NIC for queuing traffic which snort-inline requires, and the third is the LAN NIC (the computer I use for everyday work). Here's how I have my interfaces set up:

Code:

# /etc/network/interfaces
# Loopback interface
auto lo
iface lo inet loopback

[code]....

From what I understand, queuing needs to be set up on the bridge. From the documentation I've read it's done like this:

Code:

iptables -A INPUT -j QUEUE
And then to forward traffic, I did:

Code:

iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE

I've done this and am able to ping the router, obtain a DNS address from dnsmasq from the LAN computer. From the router I am able to connect to the internet (ping, links <address>...). From the LAN computer trafficking isn't getting forwarded, Firefox, links, ping all don't resolve.

Ubuntu Networking :: Using PC As A Router To Share Internet: Laptop Connects But Desktop PC Doesn't

Since I have 3 Network cards in my Desktop PC I've configured it to act as a Router using GNU/Linux Ubuntu Lucid in combination with Samba so I could share my internet connection. It works on any laptop a connect to it using any of the network cards ports [regardless of the operating system installed on the Laptops], but when I plug that same network cable to any Desktop PC [regardless of the operating System installed] it doesn't even light the LED in the netcards. From the Client PC seems like nothing is plugged in the the netcards.

Ubuntu :: Cannot Connect Wireless Through Wired Router?

Aug 13, 2011

I have searched and found no answer to this one. I have a Linksys DSL router BEFSR41 (wired) which works great. I recently got a Linksys Wireless-G Broadband router. Which also works great with my Dell mini 10 netbook running 10.04. I have two computers (wired) also running 10.04, what I want to do is use both routers with only one internet DSL connection. I have the wired (Master Router) connected to the wireless (Slave Router) and I fire up the Dell it sees it and connects but I can't connect to the internet. I can connect through my network and share files through all 3 machines. Do I need to reset the wireless, to enjoy the internet? If so the wireless came without instructions or CD.

Ubuntu :: Setting Up A Wired Internet Connection Through A Router?

Oct 13, 2010

The problem isn't with thew new computer but with my computer running Ubuntu. The problem is that I'm having trouble getting the Internet to work. Before the router I just plug my PC straight into the modem but now with the router I can't get on the Internet. I can get a connection to the router but no Internet. I know the it is not the router because I use my PS3 and it worked fine. I spend like an hour just trying to get the connection but can't figure out the Internet problem. What I did to get the connection is copy the ip address, Mac, and etc. from the PS3. Then I made a new connection and put the data in the IPV4 settings and it got a connection but I'm not sure if I did that right or just got lucky

Networking :: Configure PC For Wired/static And Wired/DHCP Networks ?

Oct 27, 2010

I want my netbook to connect automatically to both the office wired/static network and to the usual wired/DHCP networks.

wicd is wicked but netsearching hasn't revealed how to configure it for both wired/static and wired/DHCP except by manually switching profiles.

wicd's profiles can use pre/post(dis)connect scripts but I don't know how to integrate them into wicd when they are upping/downing connections on cable (un)plugging.

If it is not practical to solve this within wicd, I'll explore standalone scripts to configure eth0 on cable (un)plugging, as detected by ifplugd.

OpenSUSE Network :: Wired Router - Transfer Files Between Local Computers

Jun 4, 2011

Should I be able to transfer files between computers wired to the same router? Is the router bridging function used to transfer data between wired computers? I just got DSL and I'm new to networking. I have openSuse 11.4 on two computers plugged into a Belkin router. The internet connection to my ISP works from either computer. If I ping $HOSTNAME from either computer, the hostnames are different, but the IP address is the same which is that of my ISP. I only have the one router, but it has a bridging option. I don't know if it can do both bridging and routing simultaneously.

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.

As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?

My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
