Ubuntu Networking :: Unable To Detect Router - Tries To Connect But Fails?

Apr 24, 2010

Ubuntu 9.10 comes with rt2870, the driver for my Zonet ZEW2545, and I have had to blacklist rt2800usb in /etc/modprobe.d/blacklist.conf in order for rt2870 to work. My network adapter is able to attempt to connect to my router, but after 10-40 seconds it tells me I am disconnected again. This adapter works fine on windows.

Ubuntu Networking :: Use One Wireless Router To Connect/detect To Another Wireless Router?

Aug 1, 2010

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.

Ubuntu Networking :: Fails To Connect Vostro 1720 To Wireless Router?

Oct 7, 2010

I'm trying to find out why the wireless access point at work most of the time won't let me connect to the network. I'm using Ubuntu 10.04 on a DELL vostro 1720. The router model is D-LINK DIR-655. lspci gives me: Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01), and I'm using Broardcom STA drivers.

If I try like 10-20 times to connect I will often finally get connected and once connected everything works fine for the rest of the day. The only router I'm having this problem with is this one. In the log below, the last lines is a connectionattempt that succeeded and all the lines above those are several attempts that failed. It seemes like there is some kind of timeout issue but I'm not sure what and how to fix it.

The syslog for the connection attempts are (I have marked out MAC adesses and public ips with *):

Ubuntu Networking :: Unable To Connect To The Internet But Can Connect To The Router

Apr 6, 2011

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.

Ubuntu Networking :: Unable To Connect To Router

May 19, 2011

I'm running Ubuntu 10.04LTS 64bit. The desktop running it does not connect to my router or the internet. My mac laptop does. When I installed windows on this desktop, it too could connect. But after reinstalling ubuntu, I cannot. I tried upgrading to the latest ubuntu, but that just bricks my computer. Here is my ifconfig:

~$ ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1d:09:95:39:76
inet6 addr: fe80::21d:9ff:fe95:3976/64 Scope:Link

Ubuntu Networking :: Unable To Wireless Connect With Router?

Apr 23, 2010

I have had a router die on me and have bought another (maybe a bad buy!) The new router is Linksys WAG120n. Ethernet is fine. 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.

Ubuntu Networking :: Unable To Connect To Wireless Router

Aug 12, 2011

Firstly, the actual problem I'm having is that when I start my computer (netbook) up in the morning and try to connect to the router (wirelessly) it just... doesn't work. I've used it before, at full signal strength, and it was completely fine. It never disconnects me or anything - but if I shut down my computer, like I do overnight, when I start it up again often it's hardly getting a signal at all (or so it says) and when it tries to connect it makes the connecting animation and occasionally flashes to a circular thing like firefox's loading animation. Eventually it just fails.

I try restarting my computer, but it doesn't seem to help. The last time, I had to wait until the signal looked "full" again, then delete the settings in "edit connections" for that router and only then would it let me log in again, even though I was using the same password from the same computer (even in the same place). That only seems to help when the connection looks "full" though, and even then, not always. Normally I'd try resetting the router, but I can't because it's locked in the next room (I rent a room here and the guy with the key is rarely around) but honestly I don't think the router is causing this, for a few reasons:............

Ubuntu Networking :: Wired Ethernet Connection - Unable To Connect To The Internet Or My Router

Dec 5, 2010

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.

Networking :: Set Up A Laptop As A Router To Connect Wirelessly To ADSL Router?

Nov 6, 2009

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:


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.

Networking :: Router Dir 100 From D-link Detect Hostname Automatic?

Dec 22, 2009

I have a very simple setup

router DIR 100 4 ports
adsl connected to WAN
Linux connected to port 1
Mac connected to a port 2

I am trying to figure why linux hostname is not detected in my LAN. The strange thing is that my macs hostname is automatically detected and put in DHCP CLIENT LIST! I have scrolled the whole manual 10 times.

My Linux (Slackware 13) gets IP address automatically by DHCP server in router. Has anyone had this problem with routers in general?

Ubuntu Networking :: Replaced Router And Networking Fails

Apr 15, 2010

I replaced my wired router and networking has gone south on one of my boxes. It's a Dell tower, a few years old, triple boot (ubuntu 8.10, FreeBSD, WindowsXP). Old router used 192.168.254.* via DHCP, new one is 192.168.2.* via DHCP. The router replacement caused no problems for either FreeBSD or WinXP on this box, nor for any of the other boxes on the network (one of which is ubuntu 9.10).

Ubuntu 8.10 simply will not connect to the new router. I'm presuming that something somewhere down deep has been compromised and I just don't know where to start looking or what buttons to push to reconfigure correctly. Router status displays show an IP address of for this box, booted under all three operating systems. Using network-manager to force that static address instead of relying on DHCP does not seem to help.

Ubuntu Networking :: 9.10 Detect Wi-fi But Could Not Connect?

Jan 15, 2010

I could not connect to any wireless network on my laptop with ubuntu 9.10. Network manager detects all wireless networks avaliable, but could not connect to any of them. When I try to connect, system asks for wpa-key, but typing it gives no result. I tried home and office network, but it is the same. There is WinXP installed on the other disc partition and no problem with wireless connection at all.

I have Acer 3680 with broadcom wireless adapter 4318 (driver was installed via ndiswrapper). I've already spent hours, browsing the Internet, but it does not help unfortunately, so I'll appreciate any advice of experienced user.

lo no wireless extensions.

Ubuntu Networking :: Detect Wireless Networks But Cannot Connect

Aug 1, 2010

I have a WLAN Driver Azure Wave AW-NU222 Wireless LAN Card in my Medion computer.

After installing Ubuntu it seems to detect the wireless networks in my area. However, when I try to connect to my network, it tries for several minutes and then times out with no error message. I have set up the credentials and also tried removing the encryption (WPA-PSK) from the network itself, but it still doesn't connect.

Connect via an Ethernet cable is fine, and I know that the network is good because I can connect via my Windows Laptop and various other wireless devices.

I suspect it's due to drivers, but I'm having trouble downloading a driver which I can try and install using Ndiswrapper. The Medion website just a windows executable when I try and download the driver specific to my machine when I really need the .inf file.

Ubuntu Networking :: LAN Will Not Connect To Router But Recognizable

Apr 22, 2010

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.

Ubuntu Networking :: Can't Connect To Belkin N1 Router

Ubuntu Networking :: Cannot Connect To FiOS Router

Sep 5, 2010

I 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?
