I just installed Fedora Core on my Dell Inpsiron B130 laptop and I am having trouble connecting to the internet both wirelessly and with an ethernet cord into the router. When trying to configure my network, I dont recognize any of the ethernet adapters in the drop down list. I have been told that my wireless card is Linux compatible (dell y8029 dell wireless 1370 802.11/a/b/g mini pci). My ethernet card is a B130 Broadcom Ethernet Driver which isnt in the drop down menu either.
I read that I need to download an ndiswrapper but I dont know where to find this download AND even if I could download it to a zipdribe, I have trouble opening a USB flash in Linux becuase its not a "valid block device". This is after the command "mount /dev/sda1 /mnt/usbflash"

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:
net.ipv4.ip_forward=1
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.

For reasons that are not terribly interesting I decided it would be a great idea to remove and re-install the xserver-xorg package. Which proved to be a much larger mistake than I imagined it would be. I purged the package, and then restarted.Naturally I need to have an internet connection to use apt-get to reinstall xserver-xorg, which is where my idea falls apart.I followed the directions in the How To: Manual Network Configuration. However, after I enter the command "sudo dhclient wlan1" I get the line "wmaster0: unknown hardware address type 801" twice prior to the output that the above link shows. Then I just get DHCPDISCOVER messages until I get a "No DHCPOFFERS received. No working leases in persistent database - sleeping."
I'm connecting with WEP to a router that I know works (because I'm using it to type this on my laptop right now) and I know that the wireless adapter(RTL8187) is installed properly because it automatically connected to my network when I had xserver-xorg still installed.I'm running ubuntu 9.04.I've searched for a few hours and I'm no closer to resolving the issue.

I've recently installed Lucid Lynx 10.04 on my Dell Studio which uses an internal BCM4315 wi-fi card to connect to the internet. I was hoping it would work upon the install, but deep down I knew I'd have to tweak it a little bit to get it up and running the way I wanted. The card was instantly recognized but, at first, wasn't detecting wireless networks. This was quickly and painlessly fixed using System > Administration > Hardware Drivers, which I used to install Broadcom B43 wireless driver (b43-fwcutter). I rebooted and could not detect the local wireless networks.
I entered my password to my home network (correctly, I quadruple checked) but, unfortunately, it continuously tries to connect to the network with no successful. Occasionally I'm prompted to re-entered the password and the process repeats. The network I'm trying to connect to is a WPA/WPA2 network which I've heard to be troublesome. I haven't yet tried connecting to a WEP network but I'm fairly certain it will work and I will get back to this post when I test it in a few hours.
I'm curious if this question has been answered or if the problem has been solved and I just simply don't have the google skills to find it.

I'm having some issues getting connected with a TP-Link TL-Wn727N wireless USB adapter. I have no way to connect hard wired with the computer, but I have another working notebook to possibly download files. However, the second notebook is a Mac, so most of the posts I've found are not filling in all of the answers. Also forgot to note, I am using Ubuntu 10.10. I followed along with this and managed to get the card to find the wireless connection. However, the connection would never connect. After entering the security password the wireless icon would do it's thing and then pop up asking to ok the password again. I double, triple checked the password and it is correct. I found elsewhere that I should probably install wicd. This is where I've run into problems with finding the way to get files that I can download on the Mac and then installed on the Ubuntu computer. I managed to find this forum thread and downloaded this file I transferred the file from the Mac to the Ubuntu with a flash drive and tried to install. First the install said that Network Manager needed to be removed, so I removed it. Next it says "Dependency is not satisfiable: python-urwid." I'm not sure how to go about getting this dependency as it is not showing up in the package manager.

I finally got the driver to be installed and to be associated with the network adapter. Now the issue is the wireless network adapter won't connect to my wireless network. I am new to Linux, and am trying to get my Fedora 14 to work online, without needing to constantly be wired in (what's the point of having a laptop if you have to be stationary). Anyways my network has WPA2 personal security with a TKIP + AES encryption (I switched it from solely AES because I thought that might have been the issue).I've heard a lot of good things about Linux, but so far its been frustrating trying to get this wireless connection working. I am currently taking a course on Linux, and I am using the opportunity to learn about and maybe switch over to a Linux OS which I have heard so much good stuff about in my previous courses.

After spending several months coming up with ideas (and ultimately failing), I have found the easiest and simplest way to connect your Ubuntu desktop (or laptop w/o a wireless adapter/card) to the Internet using only a Linksys Wireless Range Expander and an Ethernet cord.
YOU WILL NEED:
Linksys Wireless Range Expander (WRE54G)
Ethernet cable
Linksys wireless router (that is providing your home/office with wireless Internet) The WRE54G can be purchased online through various websites, including eBay. They run anywhere between $10 and $40, but it's going to be cheaper than a USB Wireless Adapter (and no software needs to be installed, making it universal for most Linux distros).

I'm running a Source Dedicated Server on my Ubuntu laptop, and to connect to it via external IP from other computers in the network I need to enable loopback in my router.This was working fine, but then I disconnected my laptop for a few days, and when I came back the wireless stopped working on my Xbox. I reset the router to factory defaults, and then setup everything again. It was all working fine until I enabled loopback again and power cycled my router. Now every time I do that, the internet on Ubuntu stops working and the wireless on the Xbox stops working.
Edit: You can ignore this I guess. It seems I was actually DISABLING loopback by enabling that router option, which I guess caused this. Strange, because the first time enabling this option was the only way to get my external ip to work. Oh well, everything is fine now.

I've had my PC connected to my router since I installed Ubuntu. My router has the address and name password for my ISP. I'd like to plug my PC directly into my ISP line, but the network manager won't find the connection, and I don't know how to tell my PC my ISP's address and the name and password to logon with. I set up my router, and I know how to make the connection in XP, but I don't know how to in Linux. I have very limited Terminal experience.

I have a computer running Ubuntu, and a MacBook Pro. I need to buy a decently cheap wireless router that I can hook up to my Ubuntu so that it will send wifi signals and I can use the wifi to go online with my MacBook Pro. I was about to get one today, but remembered how Ubuntu is picky about working with things like that. I'm only going to be using it to get signals around the house which isn't that big at all.
So what would be the cheapest and decently efficient wireless routers that I can use which Ubuntu will cooperate with?

I downloaded wubi, installed ubuntu, and booted it up. Everything went smooth, it finished installing with no problems. It restarts again and I login. Firefox opens.....server not found.
That brings you to where I am now. It says that eth0 is connect. I manually changed the ip address, the netmask and gateway. Still I have no luck.
route reads as follows:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.1 * 255.255.255.255

When I start Ubuntu at work it automatically connects to the router every time. At home the router signal is quite weak but manually connecting via NetworkManager Applet 0.8 was successful for a week or so. In the past week, however, although the router appears in the list in Network Manager, it has stopped working and is unable to connect. Nothing has changed with the router or hardware in that time.
This is a new laptop which had Windows 7 pre-installed. Windows 7 connects to the home router successfully every time. I really don't want to use Windows 7 but until I can get this fixed I have no choice.
I don't know if it's relevant, but once I tried deleting the AUTO Home connection from Network Manager and was then able to connect on the next attempt, but this has not worked since.

Ubuntu 10.10 connects to a DSL modem without any problems - I mean I just plugged it in and it worked - GREAT I bought a wireless router so I could connect my netbook and now my Ubuntu machine which is simply using a cable from the wireless router now DOES NOT connect. I tried a windows machine on the wired connection from the wireless router and it connects without a problem. OF course if I remove the wireless router from the chain, i.e. simply connect directly to the modem it works straight away.

Linux and I have trying to get my Fedora 15 (x86 64bit) on my laptop to print to an Epson Stylus NX515 printer/scanner. I have the printer connected to a router through a wireless connection. I have other computers that are on the network that are Windows based and they of course are printing/Scanning just fine. The printer is located in a different room. I have been searching for a solution but non that explains how to install a printer driver for one that is connected to a router wirelessly.

I am running openSUSE 11.2 and just recently my network has been down. I'm using Gnome, but using Yast to configure my network (I'm usually forced to use wireless as I travel a lot on my laptop). Usually, when I'm connected to a wireless network, it will show up as so in the Gnome start menu, but recently, it will only say Wired there, even though I have nothing connected to my ethernet jack. I can connect wirelessly to a home router, but cannot use the wireless in any other way. I have tried manually disabling the ethernet connection to no avail. Unfortunately I am limited in my linux knowledge, so I am kinda stuck here.

When fedora initially starts up, the network manager shows all the available wireless connections available to me. However, when I select my wireless connection, it will go through the loading process where it shows the two green dots and the circular moving blue streak, then it prompts me to put in the wpa password.
This is where the trouble starts...when i input my wpa password, it will proceed to attempt to connect to my network but it never succeeds in doing so--it will keep on asking me to input my wpa password. when i finally get sick of doing it over and over again, i just hit cancel instead of retrying to connect.
After i stop trying to connect, the network manager no longer shows all the available wireless networks--the list is completely empty, and i can find no way to get the list to show up again, with the exception of restarting my computer.
I am able to connect to the internet with a wired ethernet, but id like my wireless to work.

I want to use centos as a developer server on my desktop before deploying my stuff to the internet.
I have a netgear DG834G router. It's IP address on my local network is 192.168.0.1 and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.
My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.
I don't know how to connect Centos to the router.
I have tried to play with the network manager but to no avail.
I can ping localhost, interface eth0 is there, but i can't ping to the router.
I have set the manager system/administration/network to get dhcp automatically.
I can't activate the eth0 although the hardware device says it is OK.
I've looked at firewall and iptalbes.

For several months I was using EDUP adapter with both my laptop that operated on Ubuntu 9.04 exclusively and a desktop that could also boot with XP. Soon after 9.10 was released I updated my laptop and was able to use the adapter to connect to the Net.Recently, I also updated the desktop but also made it exclusively a Linux machine. Unfortunately, I have been unable to get the wireless adapter to work again on the desktop.The OS recognizes the device as wlan0, and lsusb shows:Bus 003 Device 005: 0cde:0008 Z-Com Sitecom Wireless Network Adapter 100G+ WL -125The network manager recognises the availability of the wireless network and attempts to connect. After trying for a while it comes up with a dialog box "Wireless Network Authentication Required" and in response I enter the WPA password but with no success.The behaviour would indicate that I am entering the wrong password but I am not.I have checked it several times and compared with the password that works with the laptop.

I am having some bizarre problems with a 10.10 install which I am hoping someone here can give me a little input on. Some background info: I have a laptop which I had originally put 10.10 on about 4 weeks ago. I was using the Network Manager applet to change the MAC address by entering a valid MAC in the "Cloned MAC Address" field, and then connecting to a network. This suited me fantastically as the applet applies the MAC to any interface that connects - ie. the internal Intel card or the more often used external USB RTL8187L. For reasons which would take a lot of explaining (and now kicking ones self in the head) I had to install Windoze on the machine for a week to get some specific stuff done - but have now come back to 10.10.
The problem: So just as before, I installed 10.10, connected to my router (without changing MAC) installed system updates and other packages such as Macchanger etc and got the system working and customised how I like it. Problem is, now when I enter an address in the Cloned MAC address field and attempt to connect, the applet just sits there with the pulsing waves likes it's trying to connect but it cannot. Whilst this is happening, ifconfig -a shows that the MAC has indeed been changed. Until I remove the Cloned MAC address entry, I cannot hop on my router - or any other for that matter. Before, these steps were enough to ensure correct and functional cloning.
Things to know: This happens whether I am logged in as me or root. There is no MAC address filtering on 3 routers I have tested on (different brands). There is only MAC filtering on a 4th, and in that case, the cloned MAC is in the routers whitelist. This happens whether I specify IP details and if DHCP is used. All 3 routers without MAC control have been reset. All settings to do with wlan0/wlan1 in the network applet have been removed and re-entered. It happens on 2 different wifi cards (Intel and RTL8187L) but they worked before re-installation. I have also tried the usual commands in the terminal such as:
su
ifconfig wlan0 down
macchanger --mac (mac here) wlan0
ifconfig wlan0 up
also tried hwaddress ether 12:34:56:78:90:00 etc - The problem doesn't seem to be in changing the MAC, more the functionality of wlan0/wlan1 afterwards. I have also tried (although, it worked fine without this before) adding lines to /etc/rc.local and /etc/network/interfaces. It would be worth noting that either networking was restarted or the machine was rebooted after each alteration. No avail.
I can't think of anything significantly different that I have done to this re-installation compared to the first time, so I am not sure if perhaps in the time that it took me to reinstall 10.10, a package update has come out which has altered something and it's chucking a spanner in the works. Having said that, I even reinstalled AGAIN without applying any updates and same result. I would consider myself moderately experienced with Linux - so I am pretty sure that I am not making a complete n00b mistake... this situation is just so puzzling. I have been googling for quite some time and can find others with similar problems, but no actual solution.

I have installed Ubuntu x86 10.04 LTS onto an old Dell machine which is connected to my broadband modem and Netgear Wireless Router (WGR614 v6). The router is encrypted with 64-bit WEP and allows my System76 Pangolin Performance laptop to connect flawlessly out of the box. However, my sister runs Windows XP Professional 32-Bit on a Dell Latitude D830. This machine's wi-fi card is an Intel PROSet Wireless which recognizes the router but can't access it.
What should I do on her laptop in order for her to access the wi-fi router?

I have a Netgear DG834 ADSL router (v3) which I have used for a couple of years. Prior to that I had a v2 of the same router, but upgraded for the one that supports ADSL 2+ (here in the UK).
Recently I have been having problems with the connection often being dropped, and when I access 192.168.0.1 for the router admin page, when it is not working I get no IP address listed for that of the ISP's server, and sometimes as well the upstream and downstream speeds are listed as 0 kbps.
Usually this was resolved by rebooting the router.
However, for the last couple of days, when using Ubuntu 9.04, the page of the router at 192.168.0.1 will not load. I have tried numerous different browsers, and none of them will give the router admin page.
When I tried booting from a live CD of Fedora 13, the router admin page came up just fine, no problems (although still not getting a proper connection to the Internet).
I was going to try to use the older router I had, but so far, as I cannot access the router admin page in Ubuntu, I have not done so (not had the time, and now I am at work posting this).
So there must be a problem in Ubuntu that is preventing it showing the router's admin page. The Network connection details show that the router has given the PC an IP address of 192.168.0.6 and the DNS servers are listed, so I know that Ubuntu is talking to the router, but it is not allowing me to access its settings in any way.
