Ubuntu Networking :: SSH Connection - Router Works To Except Connection Requests

Jul 28, 2010

I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?

Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?

Networking :: Wireless Connection Only Works When Close To The Router On Fedora 13

Aug 6, 2010

I have Fedora 13 installed on my Fujitsu Siemens Laptop. I can only connect to my wireless router when the laptop is close to it. When I try using the laptop in the next room, it keeps asking for the password and eventually disconnects after 3 or 4 attempts. The wireless connection worked fine in Windows XP.

May 8, 2010

My lan connection to my router isn't working i have it plugged in the cable is good ( fyi i do have some computer knowledge) So my wireless is working right when i booted up but my lan is not. i have a @#$^ i am afraid to say what it is lol dell with their integrated ethernet card.

Ubuntu Networking :: Can't See Router Via Wireless Connection

Aug 26, 2010

I am having problems connecting to my new router. It just does not appear in the list of connections under Network Manager. It is not a problem with my laptop's wireless adapter as I can connect to another wireless router. It is also not a problem with the router itself - my Nintendo Wii can pick it up over Wi-Fi and use it and that is further away from the router. It also works if I ethernet it straight into the laptop.The router was provided by Sky Broadband and is a D-Link, pretty standard type of ADSL router with four ethernet ports, wireless and telephone cable socket. I am using the default settings for the SSID and network key, as well as the encryption type (WPA).Ubuntu version = 10.04. The wireless adapter is a very standard issue onboard Intel device but as I say, I can connect to my old Belkin wireless router no problem.

Ubuntu Networking :: Connection Gone After Router Was Switched?

Aug 13, 2011

i recently had to switch routers because my old one didnt work anymore. i have a dual boot machine with win7 for games and natty narwhal (64-bit) for everything else. i'm quite new to ubuntu, i know how to navigate the menu, change settings, install things, just the basic stuff. i dont know how to use the terminal yet except some basic commands for installing and updating software.

after my router swap, my connection for windows was back, although i had to pull out the network cable and plug it back in for this to happen. unfortunately my connection in ubuntu is still gone. i see the connection in network manager, but i cant access the internet through it. i tried setting up a new one with the same settings, to no avail. i connect to the internet directly through my router. i tried finding some documentation for it but havent had luck with that. is there some way to reset the connection? or let ubuntu set up a new one like when i'm doing a fresh install? i think that ubnuntu still thinks i'm using the old router and that this is the cause for the connection fail.

Networking :: Ubuntu - Reset Router To Get Net Connection ?

Sep 11, 2009

I'm still kind of a linux newb, so I might just be missing a little bit of knowledge here, but I've been having some real problems getting my machine to connect to my wireless network under Ubuntu 9.04.

Here are my basic specs:

Intel Pentiumâ„¢ 4 CPU @2.66 GHz

1.5 GB RAM

3 HDDs: 1 40GB Maxtor internal, 1 320GB WD internal, 1 160GB Maxtor USB external.

OSes: Windows XP Home Edition (on Maxtor internal drive) Ubuntu 9.04 (on WD internal drive)

I don't think my video card would make any difference, so I won't list it on here...

Anyway, what happens is I try to connect (I select the network SSID from the pull-down list in the NetworkManager panel menu), and it seems to connect okay to the router, but I can't get out to the net. I can pull up a terminal and ping the router's address, but I get a "Destination Host Unreachable" message. It's as if, to the computer, the router isn't even there on that level, but it can still somehow connect to it.

Now, here's the strange part. If I reset the router from another (Windows) computer on the network (specifically, the one with a wired connection to it), then I can connect just fine and I can get out to the internet.

Even if you don't know specifically, but have some good ideas as to what might work, that's fine too. I hate having to do this every day, as it affects everyone's internet connection. Granted, it's not like I'm in a strict business situation with tons of machines and multiple access points, but there are 3 of us in the house and we all share internet access from the same router (as I'm sure most people do), and I feel kind of guilty having to interrupt everyone's connection, if even only for about 30 seconds just so I can get a net connection under Linux.

Windows connects to the router/internet just fine, btw. No problems there. I'm also using a NetGear WN111 USB wireless adapter, with the Windows drivers under ndiswrapper.

Ubuntu Networking :: Wireless Connection Can't Even Ping Router

Feb 4, 2010

Previously posted under "Wireless Connection Can't Even Ping Router".I've been using Ubuntu for two years. About a year ago I switched to Kubuntu because I prefer the KDE desktop. Two weeks ago I bought a new laptop: Dell Vostro v13. I installed Kubuntu 9.10 from the live CD and everything worked! Well, almost. I also set up a home wireless network with a new Belkin N+ router from WalMart. When I try to connect to my router, the Plasma Network Manager reports that I'm connected and the assigned IP address, but I'm not truly connected! I can't even ping my own router, all packets are lost.

This problem is intermittent, sometimes I connect fine. I dual-boot with Windoze7 and it connects without problems. Also, if I connect with Windoze, then re-boot into Kubuntu, it seems to "wake-up" the connection somehow and it works. I might also add that I connect without difficulty to other routers in my neighborhood, at work, in airports, etc.My old laptop was also running Kubuntu 9.10, and it connected to the Belkin router without problems, although it was a different wireless card and driver. I also tried Ubuntu 9.10 from the live CD and it also reported a connection, IP address, etc. I couldn't ping the router from that connection either!

Ubuntu Networking :: Router Too Far Away - Failed To Establish Connection

May 3, 2010

Dual boot Vista Basic and Ubuntu 10.04 on low spec PC. I can connect to the wireless when I am next to it. I move to the room where the computer is normally used and I lose connection. I can still see it but it fails to establish a connection. Okay, sounds like it's just too far way but when I re-boot and use Vista, it works fine (1 or 2 bars, but it works). Is this a driver issue? Anything I can do apart from move my wireless router?

Ubuntu Networking :: Sharing 3g Connection On 10.04 And Vista Via Router?

May 28, 2010

i'm totally new to Linux and Ubuntu. I own a huawei 3g modem through which I connect to the internet. I plan to share the internet from that connection between my Vista pc and another pc running Ubuntu Lucid Lynx. The computer I plan to use to share the internet, let me call it Server, is equalling running Ubuntu Lucid Lynx. My Server perfectly recognises my modem and connects to the internet using it and I can browse.

I plan to connect the routers internet port to my Server using my servers network card. Then i intend to let the router do the sharing of the internet to the other computers on its own. I don't have any idea how to go about doing this. Originally, I tried a direct connection between my Server and the other pc running Lucid Lynx without bothering with the router and using the following settings which i found on an online tutorial:

Server ip 192.168.0.1
netmask 255.255.255.0
and no gateway
then on the client
client ip 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.1
I used open DNS servers for the DNS

However, i was unable to browse the internet from the client even though a connection between the two was established. Then I thought to myself, why go through this trouble, I have a router so why not go ahead and use it. But then I do not know how to do that. Using the router will enable me to effortlessly connect all my computers irrespective of operating system and ease the network creation process.

Ubuntu Networking :: Internet Connection Will Not Work Even Via Router

Jun 9, 2010

Every time I turn on my ubuntu box, it somehow kills our internet connection... yes, even through the router. The internet will not work until I call tech support and they run a line test. Then it works again as if by magic. I'm at a loss. A friend suggested maybe ubuntu is trying to establish itself as the dhcp server on the network? I have ubuntu 9.04, 32-bit, workstation.

Ubuntu Networking :: Connection Lost After Router Restart

Aug 11, 2010

My ISP pushes software updates occasionally to my router. This also forces the router to restart. When the router restarts, my ubuntu box loses its network connection and does not automatically restore it after the router comes back online.How can I configure ubuntu to restore the connection once it is available again? It happens on my windows workstation...I am using ubuntu on a box with no screen / keyboard / mouse it serves as a fileserver and I remote desktop in. Obviously if the box drops the connection it is a major annoyance. I am using version 9.10

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 :: Connection To Wireless Router But No Internet (DNS)?

Jul 3, 2011

We just set up a password for our wireless router (D-link DIR-615). WPA personal. After doing that, I can no longer connect to the internet. I can connect to the wireless router, however. Same problem for the Apple Macs in the house. We called Dlink. The fix for a Mac was to add DNS servers (4.2.2.2) under TCP/IP But there doesn't seem to be anywhere to specify a DNS server in Ubuntu.

Ubuntu Networking :: Wired Connection Works But Only By Pppoeconf

Jan 3, 2010

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.

Ubuntu Networking :: Options Email ASDL Router IP For VPN Connection

Jan 15, 2010

Email my ASDL router IP for VPN connection.My adventure with NX nomachine continues with great success. Thanks for all you input and suggestions - I am still polishing the project but it has been straight forward to date.One questions I have is how to stay current with my ASDL router's IP. I use a Canadian provider with a dynamic IP that is constant for days at a time. Without powering my router down or any power outages, my IP will change. With that IP change, I am unable to login to my desktop.One windows style program I found does the job.It emails my current IP to a predefined email. I am unable to seem to find one for linux.

Ideally I would have a ubuntu program on my desktop (NX server) that would keep me up to date on my IP via email so I can login.Anyone have any experience with that? Or have any other suggestions on how to do this (I dont know the best way to keep that IP up to date besides requesting a static IP from my provider).

Ubuntu Networking :: Sporadic Connection To 2wire Router, All Other Routers OK

Sep 7, 2010

One day I lost my WiFi connection while doing nothing particularly interesting. OK then...I investigate, and I find that it only connects occasionally, and when it does, even then it will render a page almost none of the time. I can't even ping anything. I tried going to the router's config page (192.168.1.254 for this one) and found that even that won't load. I power cycled the router, and it did nothing. I thought that the router was dying, but I realized when I switched to Windows 7 (this is a dual boot machine) it works fine. Also, when I went back to Ubuntu and tried connecting to a neighbor down the block's WiFi, it also works fine (this is what I'm using to post this message.) I did all I could to fix this, even to the point of dismantling the machine and moving cards around and such, but it did nothing. I finally formatted my Ubuntu partition and reinstalled, and it also did nothing. It also doesn't work from the Live CD. The router works fine on all the other computers in the house, wired or wireless, and also my phone and PSP's.

While connected, in Firefox, sites sit at "looking up", "waiting for", or "connecting to". It seems to be at random which one. They all time out, none of them say server not found. I thought it was a DNS problem, so I tried some DNS's I know (Google's, OpenDNS, DNS Advantage etc.) but it did bupkis.One thing I notice is that while connected, I have a fantastic signal strength of about 85%, when before any of this happened, it was more around 70%. I didn't move the antenna anywhere or anything having to do with the reception. Also, once connected, it stays connected, it's just getting it initialized that's the problem, but even while connected it doesn't seem to work well.

This is incredibly frustrating, as I did not change anything with the router at all, in any way shape or form. It just spontaneously decided to not like Linux. The router's model is 2700HG-B.Could it be that my wireless card is dying? I've had the thing for 6 years, and had no sign of it failing. I'm thinking that can't be it because it works with the same computer and network, but with a different OS. Could there be something wrong with the Ubuntu driver for my card, ath5k? I was going to say there's something up with wpa supplicant, because I use WPA-PSK for authentication, but I turned that off from another computer and it still does not work.

Again, the problem is that Ubuntu works with every router I can connect to EXCEPT mine, and Windows 7 on the same machine works with the same router. My router works with every other device in the house. I have changed nothing networking related, and even reinstalling Ubuntu did nothing. I would try it with Ubuntu on another machine, but my machine is the only wireless one in the house (and I can't put Ubuntu on the wired ones, that would PO some people),and I would try it with a different wireless card/USB thingy, but I don't have another one.

EDIT: I got some other Live CDs out, I tried Kubuntu 10.04, and Ubuntu 9.10. NEITHER WORK!

Ubuntu Networking :: Wireless Connection Requires Router Reboot?

Feb 11, 2011

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:

Networking :: Cannot Connect To Router Via Wireless - Connection Failed

Jan 6, 2011

I've been at this the last 3 hours now or so. I am not a very good with Linux, I am fine with all other areas. I have this laptop, with a Intel Pro 2200BG card. The idea was to install a lxde lightwieght on it and use PCLINUXOS, because its "easy". This computer is for internet browsing and thats it. Under the Network Center -- I can see all networks, including neighbours. When I try to connect to my router via Wireless, I get connection failed over and over.

I then tried doing all the following:
Changing the router from WEP to, WPA, WPA2 personal, WPA2 Enterprise
Changing the SSID, broadcasting to ON, changing the SSID name
I've used various different passwords, and reset the router now about 50 times. I am connecting to my Router (as Ive changed the SSID and noticed it picks up the new name). (Yes I can see the correct MAC addreess). Yes I am on the right channel, all good here.

My Nintendo DS is connecting fine with all the changed settings now. The wireless card worked fine under Windows XP (However I just removed the operating system since I really had no need for it). I've tried every other mode, it works wired. Like I had explained above, I downloaded a what I thought was an easy verison (distro), I was really hoping to get away from the crazy windows life with crazy errors and instability.

I did try enabling display log, and doing it manually by adding a connection, etc. The log tells me about as less would a windows event log: it says
Problems occurred during the network connectivity test
This can be caused by invalid network config or problems w/ your momde / router
Reluanch, etc.

I can connect to the internet fine with wvdial and wvdialconf; heck I am even posting from my PCLinuxOS FM Distro. I want to setup an ethernet connection between two PC's, one running PCLOS 2010.11 FullMonty and the other Knoppix 6.2.0. Knoppix is fine and setting up a connection is simple but with PCLOS I have been having many problems trying to set it up. I tried using the drakconnect tool but it did not work. I tried assigning it a static IP Address but the other PC would still not pick it up and to to it all I keep getting the same error message about problems during the network connectivity test!
