Ubuntu Networking :: Wifi Configuration / Error No Wireless Extensions?
Jan 3, 2010
Hello, I have a problem with wireless internet on my laptop - Acer TravelMate 2413LMI with Broadcom BCM 4318 card.
Below are ifconfig, lspci and iwconfig outputs:
ifconfig:
eth0 Link encap:Ethernet HWaddr 00:0a:e4:e6:86:b5
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:20 Base address:0x3000
lo
Link encap:Local Loopback
code....
I forgot to mention that the problem occured after linux 9.10 installation

currently running karmic on an old gateway laptop with kernel 2.6.31-22-generic and, as is par for how I handle challenges, I've jumped in with both feet - which is to say this is not a dual-boot situation. I've spent some time reading the forums (and other sources of information) and am grateful for all the knowledgeable people who are willing to share what they know.
My operating system seems to be functioning properly.I can get online via ethernet, but not via wireless. I have a lucent orinoco gold PC24E-H-FC (PCMCIA) card, which the computer isn't seeing. I am trying to follow the instructions here: [URL] to install the driver. Everything is going well until I get to the sudo make line. At that point I get the following display:
make -C /usr/src/linux-headers-2.6.31-22-generic M=/usr/src/orinoco-0.15rc4 KERNELRELEASE= modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.31-22-generic'
/usr/src/orinoco-0.15rc4/Kbuild:8: *** Wireless extensions are not enabled. Stop.
[code]....
how I can fix it so I can continue on with the instructions. (For the record - if I just continue on, I can change directory in the next line, but I cannot remove either hermes or orinoco as "no such file or directory" seems to exist.)

A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.

I have a fresh install of Karmic on a older compaq laptop. I initially had LAN access, but not wifi. I added a few Broadcom packages using synaptic, and then neither worked. Then I removed the same packages, but I still have no internet access, LAN or wifi. Here are some of my settings. vincentertainment@vincentertainment-laptop:~$ iwconfig

The adapter I purchased (Zonet ZEW2508 ) uses the Ralink 2070 chipset - a fact that originally excited me because Ralink seems to be fairly loving to the Linux community. However, despite my best efforts I can't get the thing to work. Initially I tried following directions to set up the driver you can download from the Ralink website. The directions I found were written February first, and Ralink updated the driver February eighth - so as far as I can tell the directions no longer work. After screwing around trying to figure that out for a while I decided to give ndiswrapper a go.
Initially this seemed promising. I just harvested the drivers from the CD and followed one of the many ndiswrapper directions available - most helpful seemed initially to be the Ndiswrapper Troubleshooting Guide found in this forum, however the solutions offered there didn't work either. When I throw an ndiswrapper -l into the terminal it looks promising at first, it tells me the driver is installed and the device is present, but it just doesn't work. When I try iwconfig, or iwlist scan it tells me "no wireless extensions," and "interface doesn't support scanning" respectively. The only devices even listed are lo, eth0, and pan0. There's no wlan0 or anything of the sort.

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

I have a directory of a load of files without extensions. I know what the filetype should be, so is there any way of batch renaming the files to append a given extension onto it. i.e. text would be renamed as text.txt?

Is it possible to install Firefox xpi extensions into Konqueror? I can't find anything about this. All I can determine is that this xpi is a compressed directory with javascript and config files.

I've been looking for info about Legacy OS but havent found much. I installed it and all works great except there are no active wireless extensions.My laptop have an internal wifi adapter (bcm43xx) I tried to load that driver using legacy OS network wizard but didnt work, the other is a external wireless card with a rtl8187 driver, this last one is the one I want to be up. I also tried to use ndiswrapper but can't set it up either.

I just installed Slackware 13.1 on my Asus 1215T, and I've been trying to get it to connect to my wireless network in my home. When I type iwconfig I get no wireless extensions, and ifconfig returns only lo, no wlan0. I read the Slackbook wiki and tried to configure the inet1.conf and wireless.conf but still no luck...

I have a problem to configure my wifi card, a dwa-110 from D-Link, it is not recognized when I launch System / network device control (only ethernet connections appear), and it is the same thing in Administration / network / network configuration. But if I launch administration / hardware / system devices, the last line is "Ralink 802.11 bg WLAN"... When I try to add in the window "network configuration" (from above) some new stuff, I specifying the kind of hardware (wireless) and when I have to enter the name of the card I don't see my card. On other OSes, I used ndiswrapper, but I wasn't able to install it on CentOS (dependencies required and it's hard with only a USB key to install the stuff...) How to see if the card is recognized, if I have to use ndiswrapper and so on. I have an internal PCI network card also, maybe it is this card which is recognized.

I just installed Debian with the latest testing iso, and I'm having problems connecting to the web via browser. I can ping hostnames (i.e. google.com, debian.org, etc.) from the terminal and it resolves just fine, but if I try to load a page from Iceweasel or Epiphany it says the page won't load because it can't resolve the hostname. Can someone tell me what I'm missing?the detail that I'm running amd64. I've checked iptables and found no entries, and for good measure I flushed it to be certain. I also checked resolv.conf but that looked normal, just a nameserver entry pointing to my home router. I'm new to Debian, but have used Linux for years, and I'm genuinely stumped. I'm sure the solution will smack me in the head for its simplicity, but nonetheless I need at least a shove in the right direction.

I wanna see the wifi signal strength.But when i run the command iwconfig , it tells me 'no wireless extensions'.By googling I found that I need to enable config option CONFIG_NET_RADIO.I see that this has to be done in boot which has config files.So I typed the command grep CONFIG_NET_RADIO /boot/<config-2.6.31.5-127.fc12.i686> (my fedora version is 2.6.31.5-127.fc12.i686).But I got the error as "bash: syntax error near unexpected token `newline' ".I dont know the reason.I also want to know if I have to install driver(ndiswrapper)for viewing wireless signal strength.I thought that the drivers will present default(am not sure).

A friend of mine have just migrated to Linux, and as recommended by me, He's trying Fedora 15 KDE. Everything runs just fine, he loved the OS, but there's a sad problem, his network card seems to have no "wireless extensions", which makes the system impracticable to use. I've tried searching around which card JMC250 is a single-chip PCI-Express Gigabit Ethernet Controller
with lspci
and which driver for this card
JME
is installed, with modprobe list
I've tried loading this driver with modprobe jme, no errors. And I've also tried compiling a driver I got from the manufacturer. No changes.

Just bought a netbook, ASUS Eee PC 1001PX, and got rid of the crappy XP pre-installed. first i put netbook remix on it, and tried many downloads and ndiswrapper to fix the wireless problem. then i went ahead and put another form of ubuntu on it thinking it might have the right drivers need to use the built-in wireless card, nothing. i dl all updates and bug fixes. i went to atheros to download the only driver they have for linux in the AR8132 class but still not helping. although i am not sure if i even installed. once dl it only extracted itself. i couldnt figure out how to run. if someone has this type of netbook it would be awesome. everything works on it except wireless and headphone jack. i know its just cosmetics but it would be nice if all hardware worked.

Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused.
Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.
Using lshw I found this reference to wireless
I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.

I just installed Ubuntu 10.10. I was using iBall N 150M USB adapter for internet connection with Windows XP. Let me explain about the present Windows connection :
I am using an Outdoor CPE Wimax. For mobility purpose I have connected this wimax to one LAN port of ADSL+ WiFi router ( Beetel 450 TC1 ). This ADSL+wifi router reset to Factosy settings and enabled DHCP. With this setting , I am perfectly able to connect my laptop to Internet.
When I connect my USB adapter to Ubuntu , intially it detected the signal and asked for credentials. I gave the same and network established. But I am not able to browse the net. If I give [URL]..., its going to the ADSL+Wifi's diagnosis page. With Windows , [URL]... was going to the Wimax modem. After 2-3 trial and error , now Ubuntu also not able to connect to the wifi network.

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 just purchased a RALINK WIRELESS G PCMCIA WIFI CARD VISTA/LINUX (UBUNTU).
It is supposed to be UBUNTU plug and play out of the box with no driver downloads needed.
I installed it but could not find a way to search the active Wi-Fi networks available like on my Actiontec card on windows xp. The wireless router/ethernet I have is an Actiontec setup for Qwest-DSL and Actiontec is the name of the wireless network.
Strangely I tried to choose setup a "new network" and entered Actiontec as the network name and it found the network and said it was connected to it. However the internet still is not working?

I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.
I've tried :-
-disabling ipv6..... first in Firefox, then in Kernel also
-Setting DNS.....System> Preferences> Network Connections
-setting static Ip
The system still gives trouble.
My system is Asus UL20A.
Wireless:-Atheros AR9285

When I select the wifi icon on the panel, it just shows "No network devices available". I know my network can be found when I search with my iPhone, so I know there are networks to connect to. So, I checked the drivers, and it informs me that the B43 and STA drivers are not activated. So thats not a big deal, I guess, but when I use my ethernet cord, my laptop doesn't recognize/acknowledge (I'm not sure what the right term would be)it. I'm fairly sure I can't activate these drivers without an internet connection because when I do try, a message pops up saying "failed to fetch" with some long link.
My only guess is that it could be a hardware problem, but I really have no idea. I guess the ethernet problem is my only real problem. Because after I establish and internet connection the the rest is easy to fix.I'm sure its obvious, but I'll go ahead say that I'm a novice ubuntu user. I've only been working with it for about a week, but I'm learning alot.

I just installed 9.10 and I can't detect any wireless networks. Is the card compatible with 9.10? Do I need to install any drivers? If the card isn't compatible with 9.10 is it compatible with later versions of Ubuntu? Marking this as somewhat urgent as I need to get internet access for some coursework soon, and also because my parents will kill me if they find out I've done anything unusual with the laptop because it's new and they think anything non -MS is a virus.

I am having issues with wifi on my Lenovo X220. What has occurred is that the network applet in the notification bar no longer shows me any wireless network options. When I click on the applet, the drop down shows me: Wired network: disconnected (greyed out), VPN connections, Enable networking (checked), Connection information (greyed out), and Edit connections. Missing is Wireless connections. This occurred "out of the blue" in the middle of using the computer (i.e. NOT just after a reboot or new driver installation, etc.)
I have noted that:
1. Wired ethernet works just fine.
2. Wireless (wifi) works when I boot into Windows 7 or into a fresh Ubuntu USB Start up disk (implying that this is a software issue, not hardware).
3. The hardware led for wifi is OFF (whereas the Bluetooth light is on.) In Windows or using a fresh ubuntu from USB, this light turns on normally.
This may be irrelevant, but the issue started yesterday when I noticed that the trackpoint scrolling that I had enabled using gpointing-device-settings was not working. I ran that app and checked the settings, which were normal. I then reset the computer, and found the trackpoint was working just fine, but I had no wifi. A few resets later, the problem was not solved.
