I'm using a wired ethernet dongle due to my machine not having an ethernet port, however it sometimes drop connection, how can I diagnose whether if the dongle is faulty or my system is having trouble maintaining a connection.

I've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.

My /etc/network/interfaces:
Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.
I have two laptops (Dell & Lenovo), both have wifi.
I am having one wired Ethernet connection.
I want to share this Internet connection among two system , to access Internet from both the system.
I had tried by creating a wireless network, but was not able to do so.
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.
View 9 Replies View RelatedI'm running an up-to-date Fedora 12 machine with the Gnome desktop (meaning with Network Manager). My network connection is a wired ethernet to a switch which then connects to a Netgear router. For some reason, this machine can't renew its leases with DHCP, so NetworkManager deactivates eth0, taking my machine off the network. I have to click Network Manager and enable eth0, which seems to work every time.
How can I fix it? Here are the relevant bits from /var/log/messages showing a failed DHCP request and then the successful renewal.
Code:

while my brother was browsing the web on my windows partition he had a blue screen pop up, one of the soft/hardware error ones, not a true BSOD, anyways, ever since my lan port on the computer seems to not be activiating as no wired connection is recognized. The lan port/card is directly attached to the Mother Board, it's a gigabyte motherboard in a self-build computer. I'm just wondering if there's anything I can do to troubleshoot this and see if it is truly a hardware problem or if its something else.
View 9 Replies View RelatedI 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.
View 9 Replies View RelatedI have a generic P4 desktop computer with Debian Squeeze. Since instalation my wired ethernet connection will slowely slow down and then quit when surfing the web. Sometimes it seems worse than othertimes. If it fails I usualy can get it to come back back up by going to Network Connections and clicking on "wired connection"and them just closing the window. It will work for a bit but the conection will inevitably quit in a short time again. Interstingly it seems mostly a problem with web browsers as doing upgrades, package instalations, using SMXI and things of this sort do not seem to be a problem. I have tried both Epiphany and the Squeeze default Iceweasel with identical results. Also when using Google Earth a similar situation occurs in about 2 minuits of use. The same computer running Debian Lenny with Epiphany and WXP with the dreaded IE do not have this problem.

Why isn't my laptop's wired ethernet not showing? I have a Toshiba Satellite PSAG8U-04001W.
The installation of Debian wasn't originally on this system: it was on an older laptop whose motherboard fried, so I rescued the hard drive as well as the Debian installation. However, I doubt this should have anything to do with lspci not even detecting the wired eth controller.
I have this wired problem with my realtek rtl8101e ethernet. It keeps on disconnecting randomly with my router. My computer is connected to D-link router via LAN cable. This problem does not occur in my windows xp os.
I have to suspend and resume my Debian os (wheezy 7.6 KDE) to get the ethernet connection up everytime it disconnects with my router.
These are my ethernet details

The situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.
I have a LAN (2 PC !) wire connected and I use a Huawei e182e to join the internet (If you have problem to install the Huawei on Linux, don't install drivers proposed on forums or don't try to unlock it. It's not necessary, simply install a kernel > 2.6.34 and it will install itself as a perfect plug and play). On the unconnected machine, the Internet is accessible normally from the broadband dongle, but the connection stops when I plug the LAN cable. It's normal since the PC cannot use both network connections simultaneously without a previous configuration, and the question is precisely there !
Bridging could be a solution but mobile broadband uses ppp protocol that is not on the same layer as wired LAN. brctl refuses to add the key into the bridge configuration. Vtun seems a better approach since it works more independently from the protocols, but it must be installed on both sides and the broadband dongles does not accept software installation in it. Documentation from Huawei is quite inexistent. Actually the story could be the same for a computer connected to a wired LAN and using a wireless dongle, but here bridging is feasible (not tested by me) because they work on the same layer. I tried to deactivate LAN switching in the BIOS: no result static address with gateway pointing on the other device (I tried everything) no result. How to bridge a ppp dongle with a wired LAN?
I'm having issues with my wired network. After about 5-10 minutes of turning on my machine, the network will drop out. Sometimes rebooting my pc or router will fix the connection, other times it will have no effect. Also, sometimes the connection will completely disconnect, other times it will appear to be connected (i.e. the network icon will indicate that there is a connection), but trying to ping a remote server or the router will fail.
This problem first showed up on Fedora 11 64, however I've just installed Fedora 13 64 and that hasn't helped. I'm using a brand new NIC (I've tried using the onboard NICs). The machine also has Windows 7 installed, which is able to connect just fine. Apart from changing NICs, the only other thing I've tried is switching from dhcp to a static IP address.
I have been using this fresh Debian 8.2 install for 3 days without any network problems.
What I did this morning :
- Booted in my windows partition and rebooted immediately just to remove the system from the sleep state
- Mounted a NTFS hard drive and copied some file to my .wine drive_c
Thats when I noticed that my connection was down.
I verified all the physical layer. My laptop has access to the internet tried to connect on an another router with eht0, changed the wire, nothing worked.
It seems like the interface can't get a dhcp ipv4 address even when I try to force is with dhclient, I get no offer when my laptop works just fine.
- Booted on my windows partition without changing any connection and my internet was working.
- Booted back on debian still not working...
I have a usb 4G dongle which has stated no linux support in australia from vividwireless.
The flip flop part does not exist for me in the sense I can not see the cd autorun files so I downloaded the files off the net and put them in my wine directory

As a random thought I purged the firmware-realtek package and rebooted. Ethernet works fine now??
Fresh Jessie installed this morning with KDE. Wired worked fine during installation and initial boot. Reboot after package installation and only wireless is working right now. I did install the realtek firmware as part of my normal package list.
This is /var/log/syslog when it stopped working, and hasn't reconnected since. Cable is fine as it was working perfectly with a live Ubuntu shortly before I installed the system with Debian.

I have installed Debian squeeze 6.0.1 using the CD1 of the i686 version (kernel 2.6.32.5) on my compaq presario sr1799es desktop. My machine has a ethernet card RTL8139 (RTL-8139/8139C/8139C+)(it has no wireless card). I can't connect to internet with debian.
I can connect to internet in this machine using windows xp. I also checked with the Puppy linux 5.2.5 version (with kernel 2.6.33.2) using a usb memory and I had success connecting to internet by dhcp. I already checked lots of forums with related questions but I couldn't find a solution for my problem. I'll show you the output of lspci and lsmod !grep 8139 commands:

So I have been struggling to make this happen for a bit and cannot figure it out. I want to communicate directly from my non-GUI Debian to my Puppy Linux PC. I have set up my Puppy PC for direct connection as per the instructions in the network wizard. I need to set up my Debian to do the same.
I have done the
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
in /etc/network/interfaces.
I still cannot ping the Debian machine from the Puppy one. Are there any other steps to the direct connection? (I already have the crossover cable in place)
I have also tried this with both PCs connected to a Netgear router. I CAN connect to the debian machine if it is on the router at the IP I assigned it and the Puppy PC is configured to use the router.
Is there a file I can edit or a process I can turn off? I think it's close I am just not sure what I am missing.
I currently have a computer sitting underneath a router/switch on a Local Area Network that I want to connect to the Internet using a 3G USB dongle modem. If I am connected to the ethernet and then enable the modem connection, only the ethernet LAN side works. If I enable the modem and then enable a (disabled) ethernet connection, only the ethernet LAN side works. If I keep the ethernet disabled and connect using the modem, I can get out onto the Internet, but obviously not the LAN. I need to be able to do both.

It seems I must install and configure ebtables before sharing my wireless connection to ethernet port. Is it true? (But why the article on Ubuntu community doesn't mention it?) Or I just made some mistakes?
I recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.
