General :: Networking - Impossible To Run A Network Cable
Dec 16, 2010
I have a Verizon wireless/wired router that I access the internet through. I have a desktop computer running Slackware 13.1 i386, but it is in a place where it would be impossible to run a network cable to. Would you buy a USB wireless card? Would it work with Linux? Is there another way I can get my computer networked that I am not thinking of?
I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
I thought id give 11.04 a bash and i cant connect to internet via wifi i have a broadcom network adapter built into my hp530 laptop , and my network port is broken so cant use cable connection , so i thought id go back to 10.04 , guess wat i need to d/l the drivers again ... and again i have the same problem ? i have another laptop running win 7 , anyone know how i can get the drivers or what i can do ... ? its a broadcom BCM4311 802.11b/g
At the outset I would like to tell everyone that I am still relatively a newbie in linux. I use a usb mobile broadband data card to connect to the internet, and I recently purchased another desktop for my wife. Both of us do not share any files, but I do not have a router and was wondering if I could share my connection with her using a crossover cable.I did a lot of Googling around and tried various different things, I even followed another thread in the same forum but the most that I have got is my network manager saying that connection has been established. I am however not able to see her computer under my windows network and don't know how to proceed.I don't know where I am going wrong, and considering that my knowledge of networking is at below basement level, I would really appreciate any help in this regard.
I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.
Im a long time Ubuntu user (since 5.04), but networks were never my speciality, I have a desktop running 10.10, connected to the internet trough a US robotics modem (connection eth1), and i want to share its network with my laptop running win7, over a cat5 cable (connection eth0), but the problem is I dont seem to understand what i am doing wrong, what the missing steps required, or in which end is the problem (either ubuntu or windows side).
From what I could grasp was needed googling about the subject, i already set the eth0 connection to share with other computers (in network manager edit connections auto eth0 ipv4 configuration set to share with other computers). Also using the cli set eth0 for static ip using :
Code: sudo ifconfig eth0 192.168.0.1 Now the question is what i am missing? or is everything needed already done and i just have to properly configure the win7 side (which i already checked several times)?
Here is my ifconfig output:
Code: eth0 Link encap:Ethernet Endereo de HW 00:01:29:a6:55:fe inet end.: 10.42.43.1 Bcast:10.42.43.255 Masc:255.255.255.0 endereo inet6: fe80::201:29ff:fea6:55fe/64 Escopo:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Mtrica:1
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 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.
I have a home network and I use Samba to share files. Now when I am on the network, I can see the shares just fine, but if I use a crossover cable, I cannot see or access the folders or files.My goal is to use a crossover cable from one computer with clonezilla to my server in order to use Samba to make an image of my workstation and save the image on my server.But everytime I try to connect with clonezilla I get a persmissions error and the share will not mount. I tried going to the shell and mounting as root, but that did not work either.
I have another server which is only a console and it works though I am unsure why. The share though is a mounted usb drive while on the one that does not work, it is on the internal hard drive.I was wondering if anyone had any ideas or anything I could try to narrow down the problem. Oh, I can access the share using ssh, but not samba. One other thing, the shares are set to allow read/write access to everyone so I don't see why I can not access it.
I have been encountering this problem, not only on 10.4, but on older versions too: I use a wifi router to connect my laptop to the Internet, but sometimes I need to connect directly to another computer to move some files over GLAN. But Ubuntu's Network manager doesn't allow me to configure the eth0 interface without specifying a gateway (no gateway = grey submit button), but when a gateway is specified, it always rewrites the default gw specified already by the active wifi connection and returns back after unplugging the eth cable.
Of course this can be solved by a few route commands, but this is unacceptable since it is needed to establish the cable connection without any further assistance from within and as well without replacing the default gw and thus breaking the Internet connection. Is there, please, any possibility how to prevent Network Manager from replacing these routes?
For about the past month I have been having a very frustrating problem When I boot the system with the ethernet cable attached it acts as if the cable is unplugged even though the connection light is litWhen I boot the system with the ethernet cable disconnected and wait until it boots all the way to gnome and then plug in the cable everything works fine
Can Cat5e RJ45 connector crimper be used for Cat 6 connector because I heard cat 6 connector is different from cat 5e connector and also same question for cable tester can cat5e cable tester be used for cat 6 cable?
We were moving our cluter and during this process eth1 cable(external internet cable) was pluged-out. After pulg-in that wire again cluster is not working nicely and some process including mysql is not working.
Linux Server automatically reboots when i plug in the network cable.it was working fine till 2 days back and no changes were made to it.any light on this note pls? kindly confirm if any logs are required for the discussion!
Guy Im having issues getting my NIC to work. I dont think the NIC is faulty because when I plug the network cable in I get the green and orange light and I get the below result when running lspci | grep net
I try to install Debian 8 on my desktop PC that has a wireless network card.I had already used this computer with debian 7 and I could use my problem-free network connection.
My network card is : Asus PCE-N10
During the installation, a message occured to ask me to load a firmware (rtlwifi/rtl8192cfw.bin) which is loaded from a USB key.After this, Debian-installer seems to find my wireless card but can not find wireless network.I have this message, translated from French: "The search for an available wireless network failed" and I can enter an ESSID but inconclusive.
After installing 10.04 netbook remix on my acer aspire one, I have experienced all sorts of trouble. I can't get online, not with the wireless network, or with a usb-cable directly from the router. When I try to install the hardware drivers i get a message: there are no hardware drivers installed or something like that. There are no other OS on the harddrive, just 10.04 netbook remix. Another problem is the startup. Sometimes it boots right away, other times I've have to restart/reboot. 3-4 times before it works. How comes? Is there any way to download the missing packages/firmware to a usb-stick and then install it on the the netbook?
I can't get a certain harddrive out of its mounting (screws too tight) , but I want it connected to a different computer. Is it possible to have the harddrive's powercable connected to one computer, and its SATA cable connected to another computer's motherboard? (The powercable is too short to connect it to the other computer.)
I just installed lubuntu.I don't see the possibility to share resources in my lan: there isn't the contextual menu item "share files or folders": why? is this normal on lubuntu? I have already installed samba
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.
After having solved my raid5 creation problems, I'm running into a new one: the RAID is just impossible to mount through fstab. I get a wonderful "The disk drive for /dev/md0 is not ready yet or not present. Continue to wait or press S to skip mounting or M for mount recovery."
Once the system has booted, I can perfectly run a mount /dev/md0 /media/raid and mount it manually. I've already tried mdadm.conf with UUIDs, with device names, tried several options in fstab, xfs and ext4 filesystems, nothing to do, it won't mount.
All this is running under Ubuntu 10.04 server, kernel: 2.6.32-25 server, mdadm 3.1.4 (from a Debian sid)
My network connection breaks almost every day. I don't know whose this problem - is it my system or my provider. Everything goes ok until some moment when network disappears and ping my gateway returns "Unreachable host". In that situation I usually plug out cable and plug it in again - now network works.
I wounder if there is a way to do something from console which has the same effect as plugging out/in cable? Or may be more preferred way - can I know what exactly doesn't work when network disappears? What i must repair? May be it save me from reconnecting cable
I got a new cable modem so I could get rid of the one I've been leasing from the cable company. It is a Motorola sb6120. Everything is fine with the ISP, it's approved for operation on their network, the only hitch was I had to use my Windows laptop to run their activation software.
At any rate, with the new modem installed, I hop on my Linux box and go to work. I'm seeing some terrible delays in looking up names. When I look with firebug, all the dns lookups for new names are taking 15+ seconds. First I just think maybe the names aren't cached or something is weird for a minute and it will get better, but no. After several restarts and then a couple days persevering with the new cable modem, all DNS queries are still terribly slow (including zypper, mail client, web client).
Suddenly I remember an issue I was having with, I believe version 11.1 when I first installed it. For just the computer on my network with a fixed IP address, DNS resolution was slow like this and if I disabled IPv6 then all was well. I believe there was even a patch issued back then for gethostbyname() that was supposed to fix the issue? So, when I disable IPv6, DNS lookup is back to normal. The two Linux computers on my network had been working fine with IPv6 and the old modem, though, and the Windows box is still working fine even with the new modem.
I can disable IPv6 and make it fast again, but really why should I have to?
