Ubuntu Networking :: Connect To Wireless Router But No Internet Access?
Oct 27, 2010
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":

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.
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?
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 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
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 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:
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 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 had a heck of a time trying to get my laptop running ubuntu to connect to my home network. I have managed to get it to work at my university which would seemingly be more difficult than getting it to work at home, so I know for a fact it isn't a hardware or driver issue. If I try to connect via ethernet cable from my router, it detects that I connected the cable but says "disconnected" and never lets me connect. If I SKIP the router and go from my modem directly to my laptop via ethernet cable it works great.
Using the wireless network tool I can see all of the wireless connections in my area. When I go to connect to my network it prompts me for the WEP key and when I enter it and hit connect it just keeps cycling and eventually times out and finally again prompts me for my WEP key. I know this network works as it works just fine on my Windows 7 partition. Another interesting note - both my wireless and ethernet connections both worked flawlessly and stoopid easily on the live cd but don't after the full install.
If I manually enter in the information for my wireless through IPv4 settings and enter in the Address,Netmask and gateway I can connect to my network - but then I have no active internet connection. Same deal with my wired connection. Is this because choosing this manual method grays out the DHCP?
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.
I have a complicated situation due to my goals and network structure. I have in mind a potential solution, a bridge, but I do not know whether it is feasible or what hardware it will require.
My apartment community provides residents with free Internet access through an ancient T1 line. We do not have the option of other Internet providers, so having a router and modem in the home are not an option. The T1 line is split among some 24 switches, one for each building, and each switch has one port per floor. At each floor, there is a D-link WAP, and each has a separate SSID and WEP key. Additionally, they control access at the switch level using Access Control.
I'm used to being in control of my networked environment. I like to have friends over often, and most of them have a laptop, a smart phone, or both, which makes Access Control a pain. I don't want to have to think ahead and get their MAC addresses to the IT consultant while he's here during business hours. My wife and I have 6 devices, two of which require an Ethernet connection. I use a few applications for streaming that utilize UDP (I'm not sure if the WAPs are smart enough to even handle this) and I don't like having my traffic muddled with my neighbors.
I should note that I tried extending the network with my Airport Extreme router, which apparently only works with other Apple devices. I've also looked into WDS, but that seems to require an unlikely amount of cooperation from the IT consultant on site.
The potential solution: a Linux server that acts as a router. Ideally, it could act as a webserver for a small static site as well, but let's focus on the routing. I'd like to bridge two NICs and use masquerading (Internet Connection Sharing). The public interface would connect to the WAP using WEP. The private interface would allow up to 8 devices to connect to the server.
It seems easy enough to configure the public interface, and even to bridge the connections. What I've never done before is purchase a wireless card that can accept multiple clients. Maybe they can all do this?
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.
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?
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.
I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.
I've installed ubuntu 9.10 64bit onto a usb flash drive and found that even though I can connect to my safecom adsl modem/router I can't get an internet connection, the previous versions work and it works with a Linksys router. Is this a known issue with a fix?
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.
- 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

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 changed to a 4 port ethernet router (D-Link DSL-2542B Adsl2+)with intention to share Internet access with my brother (he's on Vista).Initially it all went well,but 3 days ago there were connection problems occured on the part of the ISP. Without realized the problem,I had reset the router.This morning I've been informed by the ISP that the connection has been re-established.So,I accessed the Internet via the 4 port router but failed to do so (server not found).Suspecting that the problem was from the 4 port router,I reverted to my old Adsl router (DSL-520B single port) and without any problem I managed to access the Internet back.I really need help to configure back the 4 port ethernet router to its initial state.
Today I set my HPG50 with Ubuntu 10.10. I used network install disk, then tasksel to add Ubuntu Desktop. Everything was fine, I set up my samba shares and a few other things. I had the NM icon on the panel but did have to configure. I was on wired connection and I could surf no problem. When I went to set up the wireless, I noticed the icon was gone. I know it was there after the install. At some point the network manager icon disappeared, not sure when because I could still access the router and internet. I spent a few hours surfing google and the forums trying to find an answer. Then, after running update and upgrade I lost internet. Even though I could see the router, I connected straight to the modem, still no internet access. I unplugged the cable from that machine and plugged it into my other system and I could surf just fine.
It was clear that nm-applet was running from running nm-applet at the terminal - nm-applet - "An instance of nm-applet is already running - Warn Couldn't initialize the D-Bus manager. nm-tool - State - connected, Driver r8169, State Unmanaged, Default no. NetworkManager.State - All three entries are set to "true". It seems clear that some other app is managing my connection as I can access the router and am currently serving video to my apple tv from this system. How do I find which app is managing my connection?
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?
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 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.
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.
I have been using pppoe connect to Internet,now I want my notebook get on line,I bought a wireless router but Ubuntu(64-bite) can't connect to Internet through the wireless router.pppoeconf said that found eth0 and vboxnet0,but search concentrator failed and pppoeconf exited.How can I fix it.
Just installed ubunto 1104 and I cannot connect wirelesly to my router. When I go through the trouble shooting the recommendation is to got to the device drivers page but the link does not take me anywhere. Here is the info from the terminal.
