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
I 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've not changed my configuration, but after temporarily unplugging my laptop from the router, I can no longer persuade it to connect again.Have restarted it repeatedly, but to no avail.A similar problem has been occurring with my Huawei 3G Dongle which has suddenly started behaving.Are there any troubleshooting guides for the Network Manager's wired connections? Don't know where to start.

Laptop wireless Windows/XP

(I can go to the Internet with this server, but not able to communicate other computers on the WRT54G Wireless Network. Even though, the Linux Server is connected to the WRT54G router port.) From the Hyper Terminal Wireless laptop Windows/XP, I want to connect to my Linux Server.
I recently bought a HP laptop which is showing some issues. To make it precise:
1. I can connect to ethernet & wireless when i am at my university, which are quite good connections.
2. At my home, i share the internet with another guy. The connection is not very stable, in the sense that, sometimes the download speed is 1MiB/s, and sometime 250 KiB/s. I have a old laptop which can connect to it without any problem.
3. My new laptop can connect to it when the connection is better with download seed ~1MiB/s, but could not connect to it when the download speed goes down.
4. "could not connect" means even ping to router takes long time with 90% packet loss. But I can always get connection and ip address from dhcp although i can not ping thereafter. This is true for wired & wireless connection both. Is that a router issue? but then, why can i connect through the other laptop.

I am using ubuntu lucid and am able to connect to my ThomsonTG585 wireless router, but my mother who uses win7 is unable to connect, except by Ethernet cable, which is not convenient, how can I get her connected. When I try to connect, It it says "limited connectivity" and does not let her utilize the internet. My brother is dual booting ubuntu karmic and winXP and is able to connect on both os's. I am absolutely sure I am entering the correct pass-phrase and ssid.

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.

i wanted to know if i can use my laptop as a wifi router; with encryption password and all security so if another computer is in the range can detect the signal and then try to connect to it with the encrypt pass.
also i have one more doubt. can a wireless router be used as a wifi ethernet card and detect wifi signals nearby and connect to internet. suppose i have a wireless router and i connect it to my desktop(with lan cables) which has ubuntu installed, and theres a wifi connections nearby can i connect the desktop to the internet.
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 4 Replies View RelatedRunning Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).
It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.
I just installed 11.04 on my laptop and the wireless works fine connecting to a AT&T 2Wire router when the ac power adapter is connected. When running on battery power I stay connected to the router but barely any information is transmitted. ie. if i restart the router connection on my computer I can load a web page like google.com then nothing else will work unless I restart the connection again. If I am right next to the router it will continue to work but very slow ( takes about a minute to load ......com when it only takes 2 seconds on ac power ). When I run windows 7 everything works fine when on battery power.Also every thing works fine on a linksys router with ac and battery power.Dell Inspiron 14R Processor: i5-2400MWireless Card: Intel Centrino Wireless-N 1030Ubuntu 11.04 Natty Narwhal

View 7 Replies View RelatedI'm sure that some of us techies have found the need from time to time to have a portable wireless bridge (see ascii art below) on our jaunts into the big bad user-woods, and I am here to ask the question of HOW to pull this off, with the least installation/configuration possible, as my tech lappy is also my main computer. What I want to do is this:
Code:
(ISP) -> (wlan0 - [MyLappy] - eth0) -> (Client computer)
Basically, thats a mess, so i'll explain it further:
wlan0 grabs the netz, and a computer connected to eth0 via switch/router/crossover cable can access those netz.
1. No configuration on the client would be prime choice rib for me.
2. Client should be any OS/Arch.
Any grand ideas out there? Currently using FC10, with various extra repos enabled.
Oh, and N00by alert, I'm learning quick, and am not shy to try new/complicated things, just bear with me!
I have two network cards in my computer (Debian). One (eth0) is connected to the router which is connected to the internet, the other one (eth1) is connected to my laptop (Gentoo). Now I want to surf the web both on my computer and on my laptop. I obeyed some tutorials "Linux as router":
1. On my Debian system IP-Forwarding is on:
Code:
takada:/home/sam# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
2. Laptop has IP 192.168.0.2 and this is the output of 'cat /etc/network/interfaces' on my computer:
Code:
takada:/etc/network# cat interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
But a ping from my laptop to 192.168.1.1 (router to internet) still gives:
Code:
connect: Network is unreachable
My 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.
View 1 Replies View RelatedI have a machine running linux with 3 ethernet interfaces attached.
My Ifconfig:
My route output:
eth0 is attached to a laptop, eth1 is attached to a PC. eth2 is attached to a DSL modem, and the server is successfully acting as my internet gateway. The trouble is, my PC cannot see my laptop and vice versa. E.G. cannot ping, host seems down.
Since I have 3 Network cards in my Desktop PC I've configured it to act as a Router using GNU/Linux Ubuntu Lucid in combination with Samba so I could share my internet connection. It works on any laptop a connect to it using any of the network cards ports [regardless of the operating system installed on the Laptops], but when I plug that same network cable to any Desktop PC [regardless of the operating System installed] it doesn't even light the LED in the netcards. From the Client PC seems like nothing is plugged in the the netcards.

View 1 Replies View Relatedmy 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.
