Ubuntu Networking :: 10.04 Fresh Install No Wireless Getting Extremely Frustrated?
Jul 26, 2011
I've had so many issues with 11.04 Natty that could not be solved I just fresh installed Ubuntu 10.04 from a USB as my netbook does not have a CD drive. Well, after installing and restarting I have no wireless. I ran iwconfig and I got pan0 no wireless extensions. How do I fix this?lspci says
ken@ken-laptop:~$ lspci

00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics

I just did a fresh install of 10.04 on my system and everything runs perfect and exremely smooth, however the update manager and firefox are taking forever to load (the progress meter reads something like 2d 17hr 23m), however the internet connection is very fast.the logs are all insanely clean with the fewest errors I've ever seen, so this shouldn't be too terribly difficult to solve. Also I seem to be having a problem with the font on Firefox, every fourth letter or so has a bright streak in it. Anyway, that might be related or not but my main concern right now is getting my download speed up to par?

I decided to do a fresh install of 10.04LTS on a Dell Latitude D600 Laptopne wordDisaster I have no wireless or WIRED internet connection. After viewing another post I've provided the output of "sudo lshw -C network" command below (I've blocked out my MAC address on purpose). It appears that the lan card is not even being recognized. The card is enabled in bios (I've checked twice). I don't get it, the wireless worked fine before I did a fresh install of 10.04LTS. I can't use wireless because I have the b43 driver firmware issue that I can't resolve unless I get my wired connection working.

I just got my self a netbook. I bought the one with linux because I figured that if they sell it with linux, it's probably using h/w which supports linux. I played around with the Mi variant it had pre-installed, but it was a bit limited and slow, so I installed UNR instead.The install went fine, and UNR is really nice to use and feels faster than the Mi too which is great. However, wireless isn't working. It's got a broadcom chipset (BCM4312) which I think needs a proprietary driver, but when I use the Hardware drivers tool, it doesn't have any options to install a driver.

I just did a fresh install of 11.2 on my Thinkpad (previously running 11.1) and am having trouble with getting wifi to work properly. My wireless will not connect reliably. Sometimes it connects after reboot but then drops and will not reconnect. Below in line 4 of the status query you can see that it says DHCP4 client NOT running.

I'm a new Fedora/Linux user and I've just setup my first laptop to use Fedora 14. However, I've come across an issue and I've done a lot of searching on various forums etc and basically I'm going around in circles. I've had my PC hang already after I tried to create a xorg.conf file. I have since removed the changes I made.
I have a a SIS 771/671 PCIE VIA Display Adapter (rev 10). I got this info via the lspci command. The problem I have is that it's not letting me select a resolution above 1024 * 768. I know it has higher resolutions as when it was a Windows XP and Vista PC I had higher resolutions. There has to be an easier way to set a screen resolution that manually editing cryptic files and knowing refresh rates etc.

I accidentally downloaded a torrent of the ALTERNATIVE ubuntu 10 installer. install went fine except for the part where i had to do the networking part, think i did something wrong there (as in skipped it). past ubuntu installs worked perfect using regular installer. googleing led me to use "lshw", and the command lshw says that the network is disabled (shows correct network controller tho).

Yesterday I switched from CentOS to Ubuntu, and wanted to install TeamSpeak3 which runs on ports 9987 UDP and 10011 TCP. The TeamSpeak3 worked fine on CentOS before this.
It appears to be running and netstat -an reports:
Code:
udp 0 0 0.0.0.0:9987 0.0.0.0:*
tcp 0 0 0.0.0.0:10011 0.0.0.0:* LISTEN
I believe the only firewall for Ubuntu is "UFW", am I correct? If so, "ufw status" reports:
Code:
Status: inactive
I do have other things running on UDP (Counter Strike Source servers) and people can connect just fine.
When I telnet localhost 10011 I get a response from the TeamSpeak3 server:
Code:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
TS3
Welcome to the TeamSpeak 3 ServerQuery interface, type "help" for a list of commands and "help <command>" for information on a specific command. However, telnetting from outside just gets no answer, this is what leads me to believe it is a firewall in the way.

My wireless works with Broadcom support. The ethernet has never worked, i think when windows was still on it, it did.

After a fresh install of Ubuntu 11.04 (from 10.04) and spending several hours trying to figure out why the ad-hoc connection between my two computers (Fedora14 <-> Ubuntu 11.04) no longer worked - it had worked fine for almost 2 years with 10.04 - I've finally concluded it was a DHCP problem. This realisation (which was slow in coming!) dawned on me when I reversed my setup and configured the Fedora box as the DHCP server and everything was suddenly working perfectly! A quick internet search threw up an installation file called "isc-dhcp-server" which other Ubuntu 11.04 - related forums are also complaining about. My problem is that this file, although available in the repository, is not even installed!!!
It seems unlikely that the developers forgot to include DHCP support, so I hope someone can point me in the right direction.

I go into the settings and select "manual" and put in my IP, gateway, mask, and DNS. It never lets me use the "apply" button.

I'm familiar with linux (Debian/Ubuntu), but new to CentOS. I recently installed CentOS 5.2 on a new server for my radio station. I can log in and do everything fine, save connect to any network. I only have a Broadcom wired nic. I know the wire and ethernet jack work fine, so that lead me to the server's settings. I'm not sure if I missed something somewhere, or a similar post (I'm sorry for double-posting if this has been done before).
There is a static IP address set, and that's done correctly.
From what I've seen, someone would like to see /sbin/lspci | grep -i ether: 03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5722 Gigabit Ethernet PCI Express

I did a fresh install of Ubuntu 10.10, coming from 10.04 and the wired network connection sometimes works, and sometimes doesn't. Right now I manually removed current network from System-->Preferences--> network connections, define a new one, and reboot. This usually fixes, although I've had to do this two times in the past.
Other general info
Ubuntu 10.10 64bit, EVGA P55 motherboard, on board either net.

I have no "enable wireless" option from network manager. I successfully installed the 8172 driver, however upon enabling it causes a system freeze, and I'm forced to use the reset button. I have no clue how to proceed from here. Data that might be of use from the "how to post" thread:lsusb Bus 002 Device 002: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191S WLAN Adapter

Just tried new Fedora 11 yesterday, did a fresh install with ext3 /boot and ext4 file system, booting looks great, but wireless doesn't work. I have tried using broadcom-wl, dnmouse script, dnmouse broadcom f11 rpm, fwcutter but not ndiswrapper
Code:
# rpm -qa | grep broadcom
broadcom-wl-5.10.79.10-2.fc11.noarch
Code:
# lspci -nn
02:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)
Code:
# lspci -vvv | grep 4312
02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
Subsystem: Hewlett-Packard Company BCM4312 802.11b/g Wireless LAN Controller
ifconfig only shows eth0, lo and pan0 interfaces, and got nothing from iwconfig...
Code:
# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
pan0 no wireless extensions.
Even tried to blacklist b43 after installing broadcom-wl driver, but no luck. Broadcom-wl works fine with Fedora 10 on my laptop, is it possibly because of the new ext4 file system? Should I try ndiswrapper or install Fedora 10 again and do a preupgrade? I also use fedora at work.

I'm trying to get my wireless to work on my laptop (dell inspiron 1520 broadcom 4311). I installed the b43 firmware and was able to set up my wireless connection. However, the internet connection is extremely patchy and seems to continuously drop (in fact most of the time it doesn't work). I can ping certain sites such as Google and get all packets received.
[Code]....
Furthermore, in Firefox the opening websites only works some of the time. Sometimes the google search page will load and sometimes it won't. I've disabled ipv6 using yast-network settings.

I have had a search around, any cannot find any thing I can make sense of as to how I go about getting the above card to work with Fedora 11. Just done a fresh install (need Linux for some development) but have no wifi. My chipset is this Broadcom BCM4310. There seems to be a whole load of options, and I don't know which works and which don't:
kmod-wl
broadcom-wl
ndiswrapper
I can sit with an Ethernet cable to install/update as necessary, but really could do with wireless.

I've got a Puppy system running version 4.3.0 that I'm trying to get on the home network. I'm using a D-Link DWA-130 (H/W revision C), which has a Realtek RTL8192U chipset. I got the drivers off of D-Link's website, and they compiled and installed just fine, but when either a) I try to connect to the network, or b) while I'm browsing the web, the system locks up completely. No mouse, no keyboard, no Ctrl-Alt-Bksp to get out of X, nothing.
I'll outline my steps: Install Puppy using a "Full" HDD install (not "Frugal"). Copy the "devx_430.sfs" file (which I got from the Puppy website) from a thumb drive to the "my-documents" folder (although the exact location proabably doesn't matter). Mount it, cd to the mounted directory and execute "cp -a --remove-destination ./* /" and "sync". Copy the kernel source for 2.6.30.5 ("kernel_src-2.6.30.5-patched.sfs4.sfs") to the same directory. Mount it and execute the same commands as before. Copy the folder containing the RTL8192U drivers ("rtl8192u_linux_2.6.0006.1031.2008") to the root directory (i.e. "/"). cd to the folder in the terminal and run "make", "make install".Reboot the machine. Set up networking using the Puppy Internet Connection Wizard. HERE'S WHERE IT SCREWS UP: It connects, but after a while (e.g. just after logging into LQ through it, as a test) it freezes the entire system.
I have to do a hard reboot ("panic button"), then a soft reboot (for some odd reason the usb module won't load after a hard reboot, so the mouse won't work) to get the system working again, only to have it lock up again once it connects to the network.
Are these drivers broken? Outdated? Is there anything I can do to fix this? EDIT: I should add that this only occurs when the adapter is plugged in. If I boot the system with it unplugged, it works fine (probably because it never loads the kernel module).
