Ubuntu Networking :: Internet Through Modem Works But Not Through Wireless Router?
Jan 22, 2010
I just bought a TRENDNET TDM C4000 (=modem/ wiredrouter) and got it working. If I connect my computer with through the ethernet port directly, the internet will work. However, when I try connecting the ends of the ethernet cable on the modem and my wireless router, it's not transmitting. I know I set up the wireless router correctly because it worked with my previous modem. I just need to know how to configure my modem so that it works with my wireless router (D-Link DI-524).
I have a long wired ethernet wire to satisfy my academic needs for the internet at the moment but my mother is not able to surf the internet and it would be more convenient for myself to put the wire back to my desktop and have my laptop browsing wirelessly.
I had an ATT "2Wire" modem/router that was working but connection to the Internet was often poor. An ATT technician came to my home and swapped out the modem/router for the identical model. I changed the ESSID and WEP code to match the new unit and everything was fine with the following wireless units: a wireless desktop, two cellphones, three wireless Archos tablets, and a couple of e-reader tablets. So all seemed to be fine wirelessly. However...
My laptop (SuSE 11.0, KDE3) simply won't connect no matter what I do. I changed the ESSID and WEP info in the lappy exactly as was done with the other wireless devices named above. But no good. The lappy does see the modem/router (a good, strong signal appears in KNetworkManager). But it seems as if the modem/router is rejecting the lappy's attempted handshake using the new ESSID and/or WEP information.
I thought that perhaps there was something wrong with the lappy's wireless card, so I took it to a Starbucks to see if it would connect there on an open network, and it did without problem. So the lappy's wireless card appears to be working fine. It just won't talk to the encrypted modem/router at home. Here are the settings on the lappy. Hopefully something here is easily identified as the culprit. With all the clicking I've done it certainly is possible that I ticked something that should not have been ticked and just don't realize what I've done.
Network settings screen: Global options tab: Network setup method: user controlled with Network Manager Change default route via DHCP (ticked)
Why won't the new modem/router which is exactly the same as the old one except for the ESSID and WEP work with my lappy yet it does work with a bunch of other wireless devices?
I use Opensuse 11.2 & Edge/Gprs Modem to connect Internet.I configured /etc/wvdial.conf & /etc/resolv.conf. Now I can connect Internet using this command "wvdial MYNET" in terminal.Now I want to share my internet using Lan card & Netgear Router. If i connect my PC with Router using wire & change option ON BOOT find this device in ifup then it'll show in ifconfig command.
My Router IP : 192.168.0.1 & It gives my PC an IP automatically : 192.168.0.2
I can ping my router.. even I can browse Router Admin page in browser. No problem there.But now If i want to connect my net using wvdial command... net connected... but no data passing!!! If i disable Lan card in ifup then Edge/Gprs net connection again OK!
3G USB modem, in and using wireless router out (via ethernet) to lappy, Wii ect.We don't have a phone line just mobile phone and mobile internet because it is mobile.I have a wireless router only but need wireless to improve my standing within the house because I am seen as a net hog!
I did come across a Virgin wireless modem but it is soooo painfully slow (tested it against the USB dongle modem 3-4kb same test 1 min later 280-300kb's USB.) The wife could make herself a cuppa just waiting for the facebook login page to load!Would it need to pass on the connection bcause the USB is fully setup? then wireless is setup or would it be required to have a 3rd security setting ect in between?It would be good to use a low spec computer because I have a few. Headless too, maybe?
I have an Ubuntu server that I need to access remotely while I am at school. The server's internet connection comes first through a DI-604 broadband router and then through a Netgear Wireless router:
ethernet wall jack --> Broadband Router --> Wireless Router --> Server's ethernet port
I can manage to get the SSH to work with the current IP address (dynamic) by connecting the server directly to the broadband router, but I cannot set up DNS (ddclient on the server, Namecheap for domain registrar and nameserver) with it. I can set up DNS on the router with no issue, as it has the DNS client built in, but I cannot get the SHH to connect through both the modem and the router as mentioned above. Best case scenario, this can be fixed without having to get anything new, but if that is the case, recommendations of a new setup
Other reference info - ISP at server is Verizon Fios, broadband router set to PPPoE.
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 an HP dv2000t laptop running 9.10 with an Intel PRO/Wireless 3945ABG wireless adapter. I have no problems connecting to my wireless network when I'm within about 15 feet of the router. When I move to a different room, my network shows up the list of available ones, but I usually can't connect. When I run Windows, I have no problem connecting from the same distance. I'm using the default network manager.
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.
Earlier today I decided I wanted to switch back over to ubuntu, my internet was working fine, but as soon as i reformatted to Linux my modem stopped showing any lights under ADSL - TX and RX. and I can't connect to my wireless connection anymore. What should I doooooooo
I have a dual-boot desktop with Windows 7 and Ubuntu.Problem: Linux does not recognize my D-Link DWA-131 Wireless N USB Adapter. So, I can't access my wireless router or the internet.D-Link has a Linux driver for the DWA-131 posted on their website URL...that includes a readme file with long, strange, convoluted instructions on how to install the driver.
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 (220.127.116.11) under TCP/IP But there doesn't seem to be anywhere to specify a DNS server in Ubuntu.
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?
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":

This morning my Ubuntu 10.10 Meerkat desktop suddenly lost internet connection, but stayed connected to my netgear router. After the usual "tried turning it off and on again" methods didn't work, I booted into my Win Vista partition to find that connected no problem. I have another Ubuntu netbook and a Windows 7 laptop in the house as well as an Android. These all connect fine. It appears to be just the desktop Ubuntu.
I can ping my router 192.168.0.1 and log into it's UI via browser. I can also ssh to the box. My router does not do any filtering or blocking. I've tried disabling the firewall and changing the nameservers in /etc/network/interfaces and dhclient.conf as well as the network manager. The network card is a Belkin 54g but I can't remember the exact model no. it was bought years ago.
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 dont know if its possible or not ? I'm using 3G dongle (ppp0 interface) for connecting to internet on my laptop running ubuntu 11.04 , now i want to share this 3G connection to my wireless router(Trendnet TEW-652BRP) through eth0 interface in simple my connection should be like this
INTERNET<<<3G WIRELESS MODEM<<<LAPTOP----WIRED CONNECTION TO WIRELESS ROUTER<<<OTHER DEVICES (LIKE ANDROID MOBILE/LAPTOPS SHOULD CONNECT THROUGH THIS WI-FI CONNECTION)
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 have I fileserver on my home network. It has a static IP and is plugged into the back of the wireless router. It is fine on the network but cannot access the internet. I noticed this when I was trying to update my package list. This is what is in /network/ interfaces:
So I installed 10.4 on a new Toshiba Satellite L645DWhen I connect to my wireless at home, the Network Manager shows that I am connected but I can't reach any websites via ping or firefox. I also can't ping my router. I also don't have wired access working at all.iwconfig shows connected to correct ESSIDI can ping localhostcan't ping google:
Code: ping: unknown host www.google.com can't ping my router (192.168.2.1):
running ubuntu 10.10 on a toshiba laptop recently the wireless Internet stopped working from our netgear router, it still works for the Ienova laptop and emachines desktop using the router but this laptop will not work wirelessly internet cuts in and out on this laptop when on wireless when it didn't previously do so it reads a connection but will not load up web pages unless hard wired in with an ethernet cord.
I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code: lancer@lancer-desktop:~$ ping www.google.com PING www.l.google.com (18.104.22.168) 56(84) bytes of data. 64 bytes from 22.214.171.124: icmp_req=1 ttl=55 time=179 ms 64 bytes from 126.96.36.199: icmp_req=2 ttl=55 time=176 ms 64 bytes from 188.8.131.52: icmp_req=3 ttl=55 time=158 ms
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)
As of now, my internet works fine when connected with an ethernet cable.The problem is it doesnt seem like my wireless is working at all.The led light is orange, (its usually blue when it connects) and I cannot see my home dsl network.Is thereany specific troubleshooting steps I should take?HP dv6000 laptopwireless card: Broadcom Corporation BCM4311 802.11b/g WLAN
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
I have internet access through 3G/4G USB dongle direct into my Ubuntu 10.04 box. Works great! Now I would like to share this connection out through my Netgear WGR614 wireless (and wired) router. Any clues? I've tried the simple (GUI) instructions using Network Manager, but just can't seem to get it right. Previously, I had DSL and this plugged nicely into the WGR614 and internet and ethernet access was had by all. Now, I'm a bit confused on how to get the sharing (ethernet and wireless) between my Ubuntu box and the wired/wireless network while at the same time getting Internet access to all through the Ubuntu box.
i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

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.
I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.
