Ubuntu Networking :: Connect To Internet Using ADSL Router?
May 23, 2010
I'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.
I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).
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:
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 have an ADSL line that allows me for maximum of 4 concurrent users with external IP addreses. The IP addresses are not static (they change every 3-4days).
My current setup is as follows: * A-link Roudrunner 44B Modem connected to the main line * D-Link DI524 Router (port 1) connected to the modem * This leaves me with 3 ports and Wireless for my other machines
What I wish to do is: * Have all my machines with static IP addresses for LAN * still have internet connection
I've tried enabling DHCP on the D-Dlink Router with LAN IP 192.168.0.1 and IP range from 192.168.0.100 - 192.168.0.199. Then gave my machine static IP 192.168.0.101, subnet 255.255.255.0 and gateway 192.168.0.1....obviously it didn't work. I've tried the above with both the modem being connected to the router via port1 and WAN port... but I have the same results. I also tried to do the same without the router (direct connection between the PC and modem) still got the same results. Could it be that what I am trying to do is not technically not possible due to my ISP setup to ensure no more than4 concurrent users limit is in place.
After reinstall Ubuntu 10.04 LTS didn't recognize my ADSL router Billion 400 G.The Ethernet 1 led is off after booting.Search on web for help on this but no good results.You good people now are my last resort.I tried boot in live CD and result is the some.Check with sudo lshw.
Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.
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 router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 220.127.116.11 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 18.104.22.168 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
- CAN connect to other computers - ssh and vnc over the home network (via D-link 524 router). - CAN get an IP address via DHCP - CANNOT get internet connections - including router at 192.168.0.1 - CANNOT even ping router (but I get an IP address - weird) - Other computers on the network CAN access internet - Live CD could not access internet
results of ifconfig
I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?
This is the results from dmesg:
I have tried:
- to set proxy settings as "Direct internet connection" - disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer - Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again. - Uninstalled Crashplan which was the last software that we installed (and it was working ok).
I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).
i recently connected this router to mahh modem..http:[url]....before router connection i was able to connect to internet via "pppoeconf command" but now i am not able to connect to internet from ubuntu ..i am still using lan cable coming out or router to connect it with pc..
I connect my internet using pppoe to may DSL modem with bridging mode, and it goes fine until I try to put a wireless router between my PC and the modem. After I configure both modem and the router, I can run my wireless network fine by connecting it from a laptop, but my PC is unable to reach the modem at this configuration.
PC has address 192.168.2.100 Router has address 192.168.2.2 Modem has address 192.168.2.1 all with netmask 255.255.255.0
With bridging configuration in modem and automatic detect configuration in the wireless router, the wireless network run well, except the PC cannot ping the Modem saying that
root@firefly:~# ping 192.168.2.1 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data. From 192.168.2.100 icmp_seq=2 Destination Host Unreachable
Looks like my PC, which has Slackware 13.0, don't know how to reach the modem even they are physically connected.
1. how can I configure the modem, PC, and router so that the PC can reach the router? Do I need to do add route gateway from the PC?
2. How can I configure internet connection from the PC (before I use PPPoE)?
3. How can I configure the modem, PC, and router so that the wireless network is on?
Useing gnome network manger. I thught that is DNS resolve problem, and wrote in linksys router the same DNS as 3g huaweii modem use. Steel the some result. NO INTERNET. Change for static ip in router and try use the same gatway , but steell can't use connected at the same time to internet with 3g and local router.
Only one devace at the same time, Router have no any acces to internat. SO why 3g internet stoping working after connecting router to LAN ports? Has it some thing to do with subnet or ip range and routing table?
At work, we (like almost everyone) are still full-on windows. I am currently trying to get away from windows because I am not a fan. my current windows machine (different from my Ubuntu machine) is accessing the wireless network fine, and there are no obvious problems there. Also, my Ubuntu machine can access my wireless network at home, so I know there are no driver issues. I set up the connection for the Ubuntu machine, and it seems to be connecting OK. I can ping internal IPs and by all statuses, the connection to the router is functioning. However, when I attempt to load a web page or ping a domain or external IP, it fails. I tried to ping the IP, thinking if that worked, it's probably the DNS, but pinging both domains or IPs fails. I have looked around at forums and posts, but none of them seem to match my issue (that's probably not true, but I am struggling to see the commonality).
Here are the results of "netstat -r":

And here is "ifconfig":

After forgetting my wifi router password, I had to reset and reconfigure the router. I enabled WEP, and after I typed the password, the computer now recognises it automatically. But I can't connect to the internet no matter how long I wait. (The wired internet connection works fine.) How can I get the wifi to connect to the internet?
I think something weird is going on. On a fresh installation of 11.04, I seem to be connected to my router just fine, but I can't reach the internet or anywhere else on my network. Anybody see my problem from what I've posted? The computer is only connected via wireless (so I don't know why eth0 would be connected as well). I can't think of what I'm missing...My system seems to be connected to my router on two interfaces. "ip addr" gives:
Code: 1: lo <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
I cannot connect to internet. I just installed Fedora 12 w/ the Live CD and I have a Linksys WMP54G Wireless Card (v4.1 I believe) and it apparently installed fine upon install of fedora. It will not thought connect to the internet. It reads my connect (NETGEAR-2.4-G), my router is a Netgear WNDR3300. It worked perfectly fine on Windows XP. Like I said, it picks up my wireless connection. But when I go to connect it attempts to connect for like a minute or two then goes back to not connected.
AT&T will not help. I am trying to connect with Cable (CAT5). When I try to configure my network card with YaST here is the message received. "Unable to configure the network card becasue the kernal device (eth0, wlan0) is not present. This is mostly cause by missing firmware (for wlan device) See dmesg output for details"
I have just installed Linux Mint 8 to an Asus A6000. My problem is that the computer won't connect with my wireless router. I have tried with MAC-adress and such, but still no respons. I also tried to connect with a cable to my modem, but no response there either.
I think I may lack some drivers, to what I think is Broadcom b43, but I am not sure. I tried to download the drivers on my other computer, and transfered them to the Asus. I managed to install 2/4 drivers, but on the two others, I get this message "Failed to fetch ... Couldn't reach archive.ubuntu.com"
i've just installed opensuse 11.2 everything is working fine but i'm unable to connect to the internet through my adsl modem the network is shown to be active but after i configure the dsl connection i can't see any option from where to connect
I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.
I've only been using linux for a few days so I don't know all the tricks. I'm pretty savy configuring windows networks however.My adapter is (according to windows) a: CNet PRO200WL PCI fast ethernet adapterLinux says it is a: 21x4x DEC-tulip compatible 10/100 EthernetI do seem to be getting an ip address from the DHCP router, but I cannout ping any other ips or connect to the internet.I've tried a bunch of different options, switching things back and forth, but it still doesn't work, and honestly i don't even know what some of the options mean.
ALSO, if this helps: paladin:~ # ifconfig eth0 Eth0 Link encap:Ethernet HWaddr 00:08:A1:03:3C:99
Does anyone have an opinion on the BELKIN F5Z0142uk Enhanced Wireless ADSL Router Network Kit, I want to setup a small home LAN and this kit caught my eye, it includes a usb Wi-Fi dongle for connectivity to a desktop computer, one of my pc's doesnt have a network card so this sounds like a good idea. Whats the build quality like and is it reliable. The link: [URL]
I have a telephone connection of 1 mega internet modem huawei mt 880 SmartAX my desktop computer is connected via an ADSL PPPoE.I use Ubuntu 10.04 in Spanish and want to know how to connect a WiFi router TP-LINK TL- wr942nd to provide wireless Internet to other 2 PC, a desktop with a plaquet wireles G CNet CWP-854 and 500 series notebook olivetti olibook. The issue is that when I connect the router I can not even go online and do not know how to operate the network, I can not even connect the desktop to my internet provider
Since this is my first post, before i describe my problem, i'd like to say regrats to all of you for maintaining here such a good support community.
So, here we go: I have a headless Debian box and i want to set it up as a small office router/gateway. On the box i installed a regular NIC and a Viking Traverse ADSL+ Card which gets recognised by the OS as an 8139 ethernet card and has an embedded ADSL+ modem. The modem is accesible through the PHY interface once it gets assigned an IP. Having said that here is the actual setup:
eth0 : Viking Card eth1 : NIC (this NIC is connected to a switch) eth0 : 192.168.1.2 (internal modem is on 192.168.1.1) eth1 : 192.168.1.3 /etc/network/interfaces
