View 1 RepliesI have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.
View 2 Replies View RelatedMy problem is little different then what I've seen here. I get the same message after inputting network name and password. I click connect and it just pops up again I don't get it. I'm running Ubuntu 8.10 for Ppc (PS3) I get no internet connection what so ever just the same message. The message I get is " authentication required by wireless network " What do I need to do to connect wireless to my router with my PS3 using Ubuntu 8.10? It does connect with a Ethernet Wire. I am new with Linux.

I'm looking over the networking help files, as well as the troubleshooting and nothing seems to be working. [URL]. From this troubleshooting guide it tells me to open the terminal and type the command "sudo lshw -C network" and when I do, it asks me for my password but when I try to type it, nothing comes up. So I run it without typing sudo. It says "*-network DISABLED" which in the troubleshooting guide means that my router is off, but I'm clearly online on this computer as of right now.

I have a router with 2 IBM Thinkpads connected. One Thinkpad is running Ubuntu, and the other is running XP.
They connect to the router with no problems.
I installed Ubuntu on a Sharp Moebius laptop and plugged in the network cable.
NOTHING.
I have tried pinging the laptop; nothing.
I am not sure where the problem is, because my Thinkpads have no problems connecting to the router, with both Ubuntu and XP
my LAN just suddenly stopped working. we had a power outage, and it just stopped. it will still recognize the network, but it wont connect. i was experimenting with setting up a web server (trying to set it up on the standard distro). i know its not the network card (on board) because i can put in my pci card and it still wont connect. it will connect when in the live environment. i thought that maybe it had updated, so i tried to boot from a different (older) kernel. that still didn't help.
i stopped apache. i was experimenting with portforwarding at the time (i had everything else working on my server), but i could not get it to work. after this happened, i restored the original settings on my router. i had applied the settings only a day before the power outage. everything still works on another computer on the network (also running linux). (all computers run 9.10) its almost like my router won't assign me an ip address.
I have a new belkin N1 router which I tested in somebody else's flat. It worked fine. When I got home I reset it by pushing a paperclip in the hole for 10+ seconds to erase this flat's internet connection settings (username and password and stuff). After this I plugged it the computer and tried to connect to it (wired connection) using 192.168.2.1 (this is correct for that router, it is not 192.168.0.1). But the browser says it is offline and cannot connect. The lights of the router cycle, the "modem router" light blinks continuously and the others briefly come on and go off again, every few seconds. I tried resetting it again, several times, leaving it off for a few hours, leaving it on for a few hours, etc.
View 2 Replies View RelatedI recently just upgraded my operating system to Ubuntu 10.04 LTS and I can't seem to get my wireless card to connect to our new Verizon Actiontec router. I am using an Encore Electronics 802.11n Wireless USB Adapter (model: ENUWI-N), which had worked with an earlier version of Ubuntu and our old router. The adapter recognizes the SSID of the new router but will not connect with the correct WEP key or even with the encryption turned off. I have tried deleting the wireless profiles and manually re-creating them and still no dice. I have also gone to the website of the chipset manufacturer and found the latest drivers (RT2870USB(RT2870/RT2770)) for the adapter, which, according to the Synaptic Package Manager, I do not currently have installed.
Where do I go from here? Do I need to install the new drivers, and if so how do I do that?
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.

Now sometimes it detects my wifi router and shows its ssid in nm-applet. but when I try to connect, it tries for 3 or 4 minutes and then fails. for most of time it even does not finds my router.
I have installed ubuntu 10.10 and am really happy. I want to sort the wireless conection out now. I have been through this forum for hours today and can't get it working. I have a Broadcom wireless card, which seems to be working fine, but I am not 100% convinced.I have attached the output of some of the commands that I have seen referred to on here.
I am using the wired connection on the same router, so the router connects fine.I click on the network icon and I see the skyNNNN router in the list. I have tried connecting to it and it asks me for my password, which I provide then nothing happens until it asks me again.I have removed the security from the router and I then see the same skyNNNN router without a
lock icon. I try to connect and it still fails.I am not using an access list on the router, so there is no issue with the mac address.

View 9 Replies View RelatedI'm trying to connect to a new Belkin wireless router, but wicd refuses to connect. I've been reading some of the other threads but they haven't made much sense as the hardware is different.
The output from the iwconfig command is as follows:
When I ran lspci it told me I had a RaLink RT2800 802.11n PCI Network Controller. On the box it says it "Supports the most popular systems" and mentions Linux. I'm using a 63 character WPA2 password, which has been copied from a USB key, so I know that is correct.
I am net to this whole Linux thing. I cant seem to connect to my Linksys router. Not sure if I have to call Linksys or what.Mine is a WRT54GS

View 1 Replies View RelatedOk, so spec's on my setup: Ubuntu 9.10 on a Dell Inspiron 530.. Q6600 w/3GB RAM, 500 GB HD w/radion 2600xt and broadcom wlan NIC. My issue is that the broadcom will not connect to my router. I did some searching, found a link from this site detailing how to get my NIC to work on Intrepid, but that's not what I have. I followed that guide anyway, substituting my driver for his (guide is on sampbar.com) and nothing. It's showing now as not ready. I've installed ndiswrapper and grabbed the drivers for my NIC from my Vista install, but when I use ndiswrapper to do that, I get an error saying it can't tell if the hardware is present, then shows me it is present and it still won't connect.

Laptop wireless adapter is Atheros AR5009 802 11a/g/n. I have setup a wireless connection but it is not connecting to it. I have checked the router settings and these seem to be OK! I'll try to give any details required.
View 2 Replies View RelatedI'm a beginner in Ubuntu, I'm using Ubuntu 9.10.
Currently using a Dlink GLB-802c router and using a ADSL connection. I try to connect to the Internet but it is unsuccessful. Ubuntu is not indicating my router when I connect to the PC.
My PC is P4 and using USB to connect to internet, PC haven't a Ethernet interface.
Ubuntu 10.10 connects to a DSL modem without any problems - I mean I just plugged it in and it worked - GREAT I bought a wireless router so I could connect my netbook and now my Ubuntu machine which is simply using a cable from the wireless router now DOES NOT connect. I tried a windows machine on the wired connection from the wireless router and it connects without a problem. OF course if I remove the wireless router from the chain, i.e. simply connect directly to the modem it works straight away.
