I am trying to run a cable from my wireless router over a 75ft cat6 cable to my bedroom. I don't get any connection on my end and I don't have any other ideas. I did setup a m0n0wall box just to try. I got the network led on my server to light up in my room but nothing more than that. Lastly, I tried adding a 5 port switch in my room and then connecting that to my server and nada.
OS: Maverick Ethernet driver: tested with sky2 an sk98lin This has been driving me crazy for the last few months: if I unplug ethernet cable while my laptop is on reconnecting it sometimes does not bring the connection back.
And once ethernet is gone nothing that I try seems to consistently bring it back. Rebooting, disabling/enabling the driver, disabling/enabling NIC in BIOS, changing driver from sky2 to sk98lin, deleting connection from Network Manager, resetting the router - nothing helps. It seems to come back randomly a few weeks later. Once I used live Ubuntu on a USB stick and ethernet came back not only on a live distro but then when I rebooted also on my main OS. But when I tried that trick next time ethernet was missing in the live distro as well.
Also once I was able to revive ethernet but compiling sk98lin driver, blacklisting sky2 and rebooting. Of course next time doing the same routine did not help. The thing is - ethernet works fine with either sky2 or sk98lin and I can unplug the cable and plug it back in most of the time without any issues. But then every so often - bang and I'm stuck with only wireless until ethernet suddenly starts working again.
I just built my first pc, installed ubuntu 9.10 and tried connecting to the net through my ethernet cable and all that happens is it says cannot find server. Do I need to install network settings & if so what & where,or should it automatically detect them? As this is my first build I am a novice but am willing to listen & learn.
I have been using my laptop as a development machine for a few months now, developing php/mysql applications, and testing them offline via the same laptop by pointing the browser to url.
But a few days ago, my url stopped working and I discovered that it will now only work if I have an active internet connection plugged in. Why has this happened and how to I fix my test server so localhost works with or without an internet connection via an ethernet cable.
how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:
Three Ethernet Cables Two Printer Peripheral USB Cables The Two Computers A 2GB Flash Drive
That is all I can think of right now. I do not want to use CDs. In a way, I would like to do a network boot. So, how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? I want to put Xubuntu on it, and earse the rest of the Hard Drive. The computers getting this are the iMac G3s and the eMac G4. The eMac has 256MB RAM, 40GB HDD, and a 700MHz processor. Two iMacs have 128MB RAM, 40GB HDD, and a 600MHz Processor. The other iMac is the same as the rest but has a 500MHz processor.
I am using Ubuntu Server version 10.4, and am trying to connect to the internet via an ethernet cable. This may and probably is incredibly simple, however, I could not find anything that pertains to it.
I am running Ubuntu Linux 9.10 on my laptop and desktop. I would like to transfer files from one to the other using an Ethernet Cross Over Cable. Is there software already installed in the bundle, that would allow me to setup network drives for each machine when the cable is connected. Also how would I setup the configuration.
How can I find a MAC of hardware attached via ethernet cable? I have been working nicely with an industrial scanner that is controlled by a Linux PC via an ethernet cable, but the hard drive has died I need to get it working again. The problem is that the main PCB has a Realtek RTL8019AS ethernet controller chip: [URL] which I believe is used in the most basic way possible, applied straight off-the-shelf and unconfigured. To utilise the chip ARP commands are used to assign an IP address to the chips MAC address e.g. something like:
arp -s 192.168.2.5 00-05-a4-00-a8-f8
Unfortunately the actual MAC address was lost along with the HD Th only thing I could have a reasonable guess at is that the chip will have a default subnet of 255.255.0.0 or 255.255.255.0
How can I find out programmatically if a cable has been removed from an ethernet connector where the interface is "up" ??? Without using ping of course. Sidebar question, if I have two interfaces on the subnet how can I force a ping out a specific interface? Say, I have 192.168.5.14 and 192.168.5.13 and I want to throw a ping out *.13 and not *.14 ..
I'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.
Here's some of my specs if that's of any help: Computer is a Sony Vaio laptop model VGN-SZ370P My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller
The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...
I've recently bought a recycled computer for my office. The plan was to get an old cheap computer and use it to write LaTex documents but nothing else. However, I can't seem to get the thing to connect to the internet. I'm on a University network which has a funny setup but I don't think that's the problem.So here's the deal. I have tried this with 9.04, 10.04 and 10.10 and it hasn't worked. The computer recognizes the ethernet cable. If I issue the command "sudo mii-tool eth0" and get back "eth0: negotiated 100baseTx-FD, link ok". However, click on the networking logo on the top right, and click auto eth0, it tries to connect for about 30 seconds, then gives up. Unfortunately I'm pretty clueless when it comes to networking so I have no idea what to do to try to fix this.
Using ubuntu 10.10 (pinguy OS) i connected an ethernet cable from my girl's macbook pro to her lenovo ideapad s10-3t to transfer some DS9 episodes onto it. new enough to linux to have not been able to figure out how to access the files on the mac, so i disconnected the ethernet, and the wireless hasn't worked since. tried everything i know, and googling for a while (as well as searching again on this forum) to no avail.
Just before linking the 2 computers via ethernet, the wireless worked fine on the ideapad, always had; but not so after the ethernet connection that did nothing other than apparently kill the wireless. an "lshw -C network" command tells me i have a BCM4313 wireless card, and *-network UNCLAIMED. also, if i launch "install additional drivers", i see that the proprietary driver is not active.
How could merely plugging in an ethernet cable that happened to be conncected to a MBP running OSX.6 do that? and will that happen again? i thought linux was supposed to play real nice with other OS's, so why did a simple file transfer kill my wireless connectivity? i have no access to internet via ethernet cable, so i cannot just download the driver i need now. shouldn't it still be in the computer still? somewhere? is there a simple solution to this, or has the wireless driver been wiped out by plugging in the ethernet? is this a bug that should be reported?
Acer 5250-BZ475 laptop, fresh install of Ubuntu 11.04. Boots up beautifully as long as an ethernet cable is plugged in. Otherwise, I get to the login screen and have just enough time to start typing in my password before the entire system hangs hard - no mouse, no keyboard, can't even get to a terminal, nothing. Have to hard power off the machine.
It seems to be a problem with the wireless card trying to initialize, but there doesn't seem to be a bios option to disable wireless on this laptop, so I'm a bit at a loss as to how to fix this problem. By the way, wireless works fine if I boot up with a cable connected - I can see all the wireless access points in my area no problem. I just can't boot without a wired connection, which makes my laptop more or less useless when I'm away from home with it.
Yesterday it was everything OK in my PC with Ubutnu 10.4 and WinXP. Suddenly Ethernet stop working at Ubuntu, all what happened in between was a change of user, I trying changin user again, restarting PC, switching the cable (I have two ethernet boards) and nothing happened. It is like a virus attack, I don't know. I am writing now from WinXP in the same computer. Ubuntu says that I have no cable connected, but as you can see I am connected in Windows
I've got a Laptop with wireless broadband connection which needs to be connected to a desktop machine so that the internet connection could be shared. Both has got Ubuntu 9.1. I don't have a router or a switch. I just need direct connection with a cross over cable.
I have a wireless connection with static ip 192.168.10.150 to connect to Internet through a modem / router ADSL ip Lan 192.168.10.1. I connect with no problems. I have a wired network in the office 172.16.17.0/24 to work with the servers. the router is 172.16.17.1, my connection eth0 with static ip 172.16.17.150 work, but Internet by Internet nothing. If i disconnect the cable i have Internet from wireless. ?? What i have to do to ,to received internet by wireless and be connected ate same time to my wired network by eth0 too.
I recently installed the vt6656 wireless pci card that came with my zotac motherboard. I can associate with my ap and get an ip address successfully. When I disconnect my ethernet cable, however, my wireless interface stops responding (can't ping it). The box itself is in a place where I don't have a monitor connected to it so I cant see anything since my ssh session gets killed as soon as I disconnect the ethernet cable.
What would be the reason why the ehternet cable being unplugged, disconnects my wifi card as well? Does something get triggered? I did some testing with iptables, blocking the 8080 traffic to the wired interface, and noticed that the 8080 traffic also gets blocked to the wifi ip. I'm afraid that this never worked properly to begin with.
I've been reading too much and understanding too little. What I have: Lucid laptop & desktop. Both have ethernet > hub > internet. What I want: connect them directly by the serial ports so the laptop can access the desktop's drives, and the desktop can be retired from the internet. I've got an old DB-25 null-modem, last used for multiplayer Doom. The laptop's dock has DB-9, so the connections is desktop > null-modem > Belkin DB-25 - DB-9 cable > laptop.
I had hoped this post would get me somewhere:[URL].. No such luck. When I ping 'grin.local', the connection is through the internet. If I disconnect the hub, i cannot ping.
Dunno if there's something more I should do to enable serial connection in Lucid, or if my null-modem is no longer good. I'm also rather curious how "grin.local" manages a connection through my ISP's system. These are DHCP. Shouldn't that have required the full numerical IP?
(It's nothing to do with the hub. Checked that by connecting a third box to the hub. My ISP only hands out two IP. I couldn't ping the third box.)
I have a desktop running Ubuntu 8.04. I installed 10.04 on my laptop. When I mount my desktop music folder on my laptop and transfer files, they now only go at 100-200 KB/s. When I had 9.10 installed, they transferred at 1-2 MB/s.
This is the command I use to mount the directory: sshfs email@example.com:/home/matt/Music/ /home/matt/Music/desktop/ Is there any way I can speed it up to get it back to max speed?
I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.
What I have done so far: (1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.
(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).
(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.
(4) I restarted my router and computer. None of this helped.
how i can use VLANs. as i have red on the web, it is possible to have a switch to allocate ports to a single VLAN. thus splitting subnets on a port allocation. since i have a pc running KVM, it is possible to create multiple subnets for DMZ and LAN. thus my question is - is it possible to have a SINGLE cable connection to a switch that carries TWO subnets? so that i can decide how to distribute then on the pc?
Running 2.6.29-gentoo-r1 on a Sun Ultrasparc 10 with a Sun Happy Meal on eth0 connected directly to my cable modem. Intermittently, with a frequency between a few hours and a few days, I lose internet connectivity. Running ifconfig eth0 indicates all is well and I have a valid IP address but I cannot even ping the cable modem's management address; pings to 127.0.0.1 and eth0's IP address do get a reply but no other address I've tried does. I can 'fix' the problem by issuing
If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity. The strange thing is that the incoming traffic doesn't seem to be affected by this, my PSAD log is full of incoming scans even during the periods when I can't connect to the net. I suspect this is an ISP problem (they own the CM);
Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10. I'm having problems with my cable modem connection failing, so I've added a static route that enables me to log into the modem's diagnostics page at 192.168.100.1 when the connection drops; my /etc/conf.d/net looks like this (with the comment lines removed).
I just purchased an HP Pavilion p6710f desktop with an ralink wireless n card, and 11.04 won't recognize it in 'Additional Drivers'. I can't get it to an ethernet cable, and then check for more additional drivers (did this on an old laptop), so what can I do??
I installed Ubuntu 11.04 on my girlfriends laptop a couple days ago...had the Ethernet cable plugged in to do the install...loaded fine the first time after the install. Unplugged the Ethernet cable when I had the wireless network set up and it froze. Restarted and it wouldn't even load the desktop. Didn't make the connection at first...thought there was something wrong with Unity. After about a day and a half worth of searching Unity problems/desktop freezing and solutions, I stumbled across this:
Do you have a Broadcom card? You have probably noticed the desktop works when you run Ethernet but it locks up when your wireless connection is active.
You'll need to upgrade the kernel to fix the issue. 184.108.40.206 did it for me.
11.04 just runs fine now.
This solution was to update the kernel, but that didn't work for me. Now I'm stuck.
