Ubuntu Networking :: Broadcom WLAN - Connection Refuses To Load Anything Off The Internet / Local Network
Jun 6, 2010
I dual boot windows xp and ubuntu 10.04 LTS and the wireless card works perfectly fine in xp so I know its not a hardware/network issue. In ubuntu, it detects wireless networks, will connect to network and work for about 20 seconds.
[Code]....
and it continues on after this alternating between a normal 20ms and high ping over 200ms. The connection refuses to load anything off the internet/local network.

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?

I have a wireless cable modem/router and a PCI-E 1x wireless card in my desktop PC. It works perfectly until I connect my Ethernet cable to my local router and printer, no more internet connection. I am guessing there is a setting somewhere that tells the networking software that the hard wire connection is the primary internet gateway. How do I tell it to use the wireless as the primary gateway?

Have a domain registered on a public ip. The domain server for the domain is on the same local network as the web server that uses the domain. The web server naturally has a local and public ip address.
The problem is that whenever I try to access the domain from my local network the lookup for the domain fails, as it cannot find the server from the local network. What's the most painless solution to this problem?
TL;DR: need for my domain to be accessible from both my local network and the outside world, now it's only from the outside which is a problem.

I'm trying to install the drivers for my Wlan card, I've downloaded the drivers in the tar.gz-file from Broadcom and untar-ed it in my /home/<username>/hybrid_wl-folder and cd'ed to it and I try to run "make" but I get an error: KBUILD_NOPEDANTIC=1 make -C /lib/modules/'uname -r' /build M='pwd' make: *** /lib/modules*2.6.31.5-0.1-default/build: No such file or directory. Stop make: *** [all] Error 2
I'm getting really desperate, I need my Wlan on Wednesday. I'm following the README but this is what I get.

I have two networks. One of them is wired, the other is wireless. The wired has an internet connection and a few other computers connected to it. The wireless network has a few hosts connected to it too, but it has no internet connection. What I've been trying, fruitlessly, to do, is make all connections that are bound to the internet, or my wired network, be routed that way, and all the connections to the hosts of the wireless network go that way.
Here's the setup..
Wired:
192.168.1.0/24 Gateway = 192.168.1.1
Route internet through here
Wireless
192.168.2.0/24 Gateway = 192.168.2.1
If my computer sends a packet to the internet, it should be routed through 192.168.1.1 If I send a packet to one of the local hosts of the wireless network, it should be routed through 192.168.2.1. Here's the routing table I've set up(This is one of many configurations I've tried)
Code:
$ ip route show
192.168.2.1 dev wlan0 scope link
192.168.2.0/24 via 192.168.2.1 dev wlan0 src 192.168.2.4
[code]....
With this, and everything else, I get destination host unreachable when pinging. The strange thing is that, if I unplug my eth cable, reboot and connect to the wireless network, everything is fine and I can access the router and the others. I'm trying to improve my networking skills, as I've had this of setting up a small linux box as a router for quite some time, for the fun of it, but I need to get routing under control before I go ruin my network.

I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?

I Have Ubuntu 9.10 Server installed and for some reason after updating our server with the ubuntu update manager, we can no longer connect to the network via remote desktop, let alone not even able to ping. We are actually able to connect to the internet itself just fine so I dont understand why this isn't working

I'm having trouble setting up new Alix URL... system with a wireless card. I got the card from an old working Buffalo AirStation router. The card is a WLI-MPCI-G54 and is using Broadcom BCM4306 chip. I've installed Debian on the system.My goal is to make a wireless access point by using hostapd authentication service. I thought it might be a good idea to verify that the wlan-card is working properly first, but it can't seem to detect my local wlan.

I have Ubuntu 10.04 installed and can browse the internet via cable, but wireless isnt working. My wireless driver is "Broadcom 802.11b/g WLAN".
In the windows device manager, I found the corresponding inf file to be oem20.inf which I tried to install it through "Setup Windows Driver" but it gave an error saying invalid driver. I also tried installing the Broadcom STA driver, but that didnot help.
I am dual booting with Windows 7, and i installed ubuntu through the windows wubi installer. My laptop is HP Pavilion dv4. I have installed the regular Ubuntu desktop and have made all upgrades. The results from lspci command i have added below.
gowda@ubuntu:~$ lspci

I have Lenovo Notebook 3000 N100 with built in wireless - Broadcom BCM4311 802.11b/g. The seems to be properly installed(as per the screen shots) but still I can not see any wireless networks. I checked out most of the forum but could not find any exactly matching situation. find the attached results of the below command which might give you idea : sudo lshw -C network
As per one of the screen shot it seems that "This drive is activated and currently in use" still I can not see any routers(including mine) which I can connect. Also the Wifi LED is not glowing.

I have an HP Pavilion notebook with a Broadcom WLANcard that had been working very nicely in Fedora Core 10 until this evening, when I took my notebook to a conference room where there was no internet access. (I tried to connect to wireless networks, but there were none in the area, as I discovered.) am now unable to connect to my local (home) wireless network as the device is now non-existent . Can someone please walk me through the steps to fix this or re-install it (I have tried reinstalling broadcom-wl, but that didn't help). My lspci listing is reproduced below:
Code:
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03)

I patched my wireless driver in order to support packet injection. Using this tutorial:
- Install the Firmware:
Code:
- Create new directory:
Code:
- Now disconnect Internet and unload all your driver (use rmmod command)
- Move/copy the Compat-Wireless patched in /usr/src/drivers directory and unpack the drivers:
Code:
Blacklist the wl driver: (STA driver)
Code:
Currently I'm running Ubuntu 10.10, Kernel 2.5.35-29-generic. I have a Broadcom 4318 for my WLAN and a Broadcom 4401-B0 for my ethernet. I followed the tutorial and I managed to get packet injection working on my WLAN; however, my ethernet connection isn't working. I tried sudo modeprobe b44, but I get the following message:
FATAL: Error inserting b44 (/lib/modules/2.6.35-29-generic/kernel/drivers/net/b44.ko): Invalid argument

We are in the process for Integration Network with our Government Network.
Let say that our network are 192.168.0.0/24
And the Government network are 10.0.0.0/8
I want to know if the local network can resolve the internet names in Government Network. I am using Bind for DNS.

So I've recently installed Kubuntu 10.04, and after the first and second runs, the system refuses to connect to the network/internet. I'm not sure why this is, or how to fix it. It shows up in ifconfig, but other than that I'm at a loss. The Knetworkmanager applet says "Disabled" when I hover over it, and no connection can be made to the internet (apt, Firefox). I'm running x86, with a Biostar T5XE mainboard (Realtek RTL8168D/8111D network chipset). The logs don't seem to indicate a problem, though I could be wrong. The connection is known good: it connected before, but it won't now.

I have local and remote networks that have various printers. I can add any printer (local or remote) to any PC, except for one PC that's refusing to allow remote connection (it used to, but doesn't now!). The problem PC has two printers connected and work OK as a local printer, but both display same problem when attempting to connect from any remote PC via YaST. Using 'Connection Wizard> CUPS Server' connection method requires IP address of remote PC and printer name. But if I correctly select either of the two printers I get an error message:
"PING 192.168.1.149 (192.168.1.149) 56(84) bytes of data.
64 bytes from 192.168.1.149: icmp_seq=1 ttl=64 time=1.12 ms
Both printers are set to 'Accept Print Jobs' and 'Share Printers> Allow remote access' permits all networks to connect. why this PC is requiring the root password?

I am currently working on a project related to packet sniffing which has been implemented using the concept of raw sockets. I am using C language.I am able to decode the following details from the packets received from a local network,like:
source and Destination Mac Address
source and Destination IP Address
source and Destination port no
But I am having trouble in decoding the domain name when an user in the local network is logging onto internet.For eg. if a user in the local network is trying to log on to web using his browser say if he has logged on to url then from the packet I need to get the following details
source Mac Address from which user had logged on
source IP Address from which user had logged on
domain name

I installed Ubuntu 9.10 using the default setup (Gnome I think) and on my Gateway Notebook using a wireless connection. It appears to be working great and I can even see my Windows drives and network storage on my home office systems.I have also set it up to run my favorite Bible software on Windows running under VirtualBox. I then installed the KDE Desktop so that I can select either desktop when logging on.
However, once I am in the KDE desktop, I cannot connect to the internet. I have checked and double-checked and the wireless settings seem to be the same on both the Gnom and KDE Desktops but still no network or internet connection when using KDE. I might mention that I am using the 64 Bit version of Ubuntu.

I'm trying to setup network server for a week now and I was able to setup network in which i can ping the other workstation that is connected to my switch which is also connected to my server and I can also ping the server from local workstation.
I have 2 NIC, I use eth0 to dial to my dsl connection(ppp0 has the IP of my internet) and I use eth1 to connect to the switch and use to connect to the other local workstation
Now my problem is I don't know how can I share the internet connection from my eth0 or the ppp0 to my eth1 to the network, what do I need to be able to share the internet connection to the workstation that is connected to my switch.

I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
eth0
Link encap:Ethernet HWaddr 001:aa0:91:a7:51
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisons: 0 txqueulen: 1000
RX bytes: 0 (0.0 B) TX bytes: 0 (0.0 B)
[Code]...
If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.

I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?

I just installed Ubuntu Netbook 10.10 on my Lenovo ideapad S10e. Under the network manager it says that firmware is not installed for the wirless card but that is something for a different day. On the ethernet connection it attempts to connect via dhcp and then comes up saying it is disconnected. I attempted to set it as a static connection, when i do that it shows that its connected but I still can not connect to the internet.

I've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?

I've read a lot on the internet about various ways of doing this but i've been unsuccessful each time. Basically what i've done is accidently un-installed network-manager because I was having trouble staying connected on my WPA network. The easiest way of reinstalling it I know of is using the CD but I don't have a CD ROM drive and the pen drive I used to install it I no longer have.
I tried using a program called Keryx but you need python installed and from some reason this doesn't come with ubuntu 10.10. I've also downloaded the .deb packages but I still need to download 200kb which is a killer. I've also downloaded it from here too [URL] but the install file makes no sense to me as i'm not a massive linux user. One last thing reinstalling isn't really an option as i've already put a lot of time into setting up this computer.
