I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

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 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
Code:
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":
Destination Gateway Genmask Flags Metric Ref Use Iface

And here is "ifconfig":

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 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 got two issues with my wifi usb adapter:
1) it cannot see any networks around
2) i cannot setup it in master mode to use my PC as a router
As far as i can see, the device is recognized and the correct driver (rt73usb) is loaded. I was able to connect to a laptop somehow (the laptop could see other networks and the adapter's PC-to-PC network). I'd like to make it work as a router, i.e. share my internet connection (eth0) via wlan0. Here is what i have:
Code:
Ubuntu 10.04
Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux
TP-Link TL-WN321G wifi usb adapter as seen as

I moved to Berlin recently and I got wireless internet through an access point. I'm supposed to use the laptop's built-in wireless netcard to access the internet. This usually works in windows (connection falls out from time to time), but I have yet to make it work in linux. I'm using OpenSuse 11.3 64-bit and the Knetwork manager. Most of the settings in the network manager are correct, but it keeps wanting to use system certificates for the server. By that I mean it keeps checking 'Use CA System certificates'.
So I can't choose the CA-certificate supplied by my internet provider. I keep removing the check-mark and pointing it to the 'hotzoneCA.der' certificate. I also got a 'personal' certificate, in lack of a better word. Its called 'jacob_collstrup.p12'. The Knetwork manager seems to accept the 'jacob_collstrup.p12' certificate, but not the other one.
I just put the certificates in a folder like this /jacob/home/hotzone/zertifikate/ I can see the network fine using the Knetwork manager, and the signal strength seems ok. Not too good, but it shouldn't be a problem. I might have messed up the system, since I first tried this guide, prior to experimenting with Knetwork Manager:
1. (had to run this one as su)
Code:
wpa_supplicant -w -i wlan0 -c /etc/wpa_supplicant.conf -Dndiswrapper -dd �t
2. (This was supposed to be put in a wpa_supplicant.conf file)
Code:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
opensc_engine_path=/usr/lib/opensc/engine_opensc.so
pkcs11_engine_path=/usr/lib/opensc/engine_pkcs11.so
pkcs11_module_path=/usr/lib/pkcs11/opensc-pkcs11.so

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 need to connect to my router using only CLI, specifying an username and password, preferably with a single command line, so it won't be interactive, 'cause I need to include the command in a script.

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.

trying to run 10.04 netbook live from a memory stick with a view to installing it on my laptop. However although I can see my wireless router and connect to it I cannot access the internet. I have tried this on my laptop and desktop with the same result. I was however able to download Seamonkey browser using the software manager....this also cannot access the internet. Both of my PC's have no problem when using XP or Linux Mint.
I have also discovered that if I piggyback, using Ubuntu 10.04, on a neighbours open wifi link I can gain access to the internet. My wifi is using WEP protection but as I said I can set the link up to the router, entering the appropriate key code, and have a good signal strength, I just cannot access a google search page.

I have a new Acer Aspire One, model D250-1958. It uses the Atheros AR928X. I've tried Ubuntu Netbook Remix 9.10 and Ubuntu Netbook Edition 10.04, as well as the conventional Ubuntu. Everything works beautifully, except no wireless. The netbook picks up the signal, but when I provide the Key it fails to connect, and eventually prompts me for the key again.
I've tried to research this on my own, but haven't found a solution. In particular, the solution reported by narnie for his Acer Aspire One D250-1584, <HERE>, didn't work for me.
I'd really like to get this working. The netbook will be much less useful if it can't make use of our wireless router.

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)
[code]....
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?

Upgraded broadband service yesterday and now using a combined router and modem (Virgin Media Hub). But I now have no wired or wifi internet connectivity on either of my ubuntu 10.10 systems. I tested it on my work laptop which uses Window and it works fine for wired and wifi.
With 10.10 I no longer have a network icon upper right panel to check, so not sure how to set up wireless. Both machines have static IP addresses and are able to ping each other but there is no internet connection on either.

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
When I boot in Windows, wifi works fine.

I'm dual booting windows 7 64 bit and Ubuntu 10.1 64 bit on my Dell Inspiron 11z with an embedded WiMAX/WiFi Link 6050 series wireless card made from Intel. I only use it for wifi, not 3g or wimax. I installed the latest driver from intellinuxwireless.org, iwlwifi-6050-ucode-41.28.5.1, but it still doesn't seem to work. I ran these terminal commands from another thread:
cd Desktop/wlwifi-6050-ucode-9.201.4.1
sudo cp iwlwifi-6050-4.ucode /lib/firmware
sudo chmod 644 /lib/firmware/iwlwifi*

After running "sudo rmmod -f iwlagn sudo modprobe iwlagn", I get this read out for my wireless card.

In the ubuntu help section it tells me to flip a manual wifi switch to enable it, but pressing my windows wifi button, F2, doesn't appear to do anything while in ubuntu. The only experience I have working with linux is typing some terminal commands on my android phone to root it.
