Debian :: Wireless Network Not Detected?
Aug 22, 2010
I just did a fresh install of debian (amd64) on my laptop (Dell Inspiron 1520). My wireless network is not being detected, but I'm pretty sure that my wireless device IS being detected. During the installation, I got a message about some firmware .ucode file not being found. It asked me to put the file on a usb stick (which I got online), and I did that. It didn't complain after that, but I got the same message again later on, but again it didn't complain when I continued the installation.

I have a D-link dir-635 firmware v. 2.30eu (latest) and a USB WLAN adapter D-link DWA-140 802.11n. The driver seems to be installed correctly since lsusb lists it correctly and all the wireless networks in the vicinity are detected including mine. When I try to connect however NetworkManager says it is activating but after awhile the windows with the newtork password appers. dmesg output:
[ 5509.487262] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 1
[ 5509.684014] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 2
[ 5509.884020] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 3
[ 5510.084014] wlan0: direct probe to AP 00:1c:f0:71:03:88 timed out
So it is able to determine the AP:s mac address but each time it times out.
I have tried disabling the security on the router but no luck.
Not sure what to try next. I have checked some of the tips supplied in these forums but none seem to handle the issue I am having.

an issue with my broadcom wireless that is using the bcm4312 driver. I installed the b43(?) cutter firmware from the command line and now my network is detected but it just won't actually connect to it. My router has wpa security enabled but i think it worked with it before.

I am using a Compaq presario laptop. I installed Ubuntu 11.04 (32 bit) within windows 7.Initially my WiFi was running fine in Ubuntu without me doing anything. Now suddenly Ubuntu has stopped showing any of the WiFi networks. I have not done any changes in Ubuntu.When i booted to my Win 7, it was able to detect the network. I uninstalled and reinstalled Ubuntu, with no avail. But Ubuntu is able to detect the wired network when connected. I am at a loss.

I have downloaded and installed Fedora 10.Now I am setting up the network and in the 'network configuration' it finds the wireless device (ralink) in the 'hardware' section of the configuration - I set this to eth0 (it originally set itself to wan0 and I still had the same problems, now it doesn't give me the option to put it back to wan0).Now I goto the devices tab and try to set up the device with eth0 - which it seems to find.But when I goto activate the device it tells me that eth0 cannot be found

I have an nc8000 that gives a "104 unsupported wireless network device detected" error when I plug in my Intel wifi card that I acquired recently. Based on reading, this is a common HP problem due to non-native HP hardware. If I insert the Intel Pro card after the HP boot screen, 10.04 loads just fine and Ubuntu detects the card.

2) Wireless Brand, Model and Wireless Chipset: 02:04.0 Network controller: Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection (rev 05)

I am running debian testing dist-upgraded to sid with the latest gnome-shell. All is fine, I have recently moved to a new house and noticed that network manager wont detect my home wireless network. It does scan for networks and locates SSIDS from other local networks including my neighbours wifi where I can connect but will not detect mine. The modem router used is a zte quite popular in Greece and I have the broadcom wl driver installed. By the way since it is a dual boot machine - nasty win7 connect just fine and so does my mobile phone...

I have been Linux user(Ubuntu)for about 3 years since my switching from Windows. Although I did not have any complain against it, I wanted to try Debian Lenny. I have already partitioned my disk and installed Debian. Everything worked fine according to my expectations except for one thing: wireless.I tried different things to get it works without result. The light indicator of my computer seems to be working but the Network Manager does not detect any signal. In Ubuntu the wireless is detected automatically even using the Live CD.

I have searched and have not found anything specific to my issue. I am currently using NDISWrapper to load the bcmwl15 driver and when it's active it works beautifully.Problem is sometimes at boot, the card doesn't "turn on" and I don't know how else to describe it. The OS does not even detect that the hardware is present. I have disabled wireless hotkey in BIOS. The only way to make the wireless card "active" is to reboot with the wiredconnection to the router. After doing that the wireless card "wakes up" and works awesome.Is there anything I can do to make sure the driver load at boot?mes I get the error that NDISWrapper is not modprobbed when I go to network configuration and if I wish to do i now? I don't know if that has anything to do with the boot sequence. Using the <modprobe ndiswrapper> command as root does nothing permanant

I'm going to come right out and say I am a complete novice with Linux/SUSE. The equipment I'm having a problem with is a little web-server that was purchased by my employer that has, quite suddenly, stopped functioning. I was changing the IP address within YaST, at which point the device offered to update itself, which I saw no harm in. Post-update, however, I was unable to so much as ping the device.
I tried "ifconfig eth0": "Error fetching interface information: Device not found." I went into network settings via YaST and found that there are two cards now listed as: RTL8111/8168B PCI Express Gigabit Ethernet controller Both IP addresses are "Not configured". The information pane, for both cards, cites:
RTL8111/8168B PCI Express Gigabit Ethernet controllerBusID : 0000:02:00.0 Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. The only difference in either of the cards is the BusID (0000:02:00.0 and 0000:03.00.0)
I can neither edit nor delete either of these cards. As I mentioned, I am a total Linux novice, and am at a total loss for what to do next, or even how to find critical information about the system itself. I know enough to check dmesg, but not enough to have any clue what to look for in the output.

I have had no problems connecting to any of my wireless networks in the past. Right now I am at a friend's house and can't get internet access with my laptop. I have entered the appropriate fields in /etc/network/interfaces (as I usually do)
auto wlan0
iface wlan0 inet static
address 192.168.2.64
netmask 255.255.255.0
broadcast 192.168.2.255
gateway 192.168.2.1
I checked this info with the router's web interface and everything seems fit. The network does not have a password. I have tried adding "wpa-ssid belkin5g" and "wireless-ssid belkin54g", and neither one works (can't ping the router after bringing wlan0 down then back up). I have also tried connecting with DHCP instead of setting a static address.

I have configured a wireless pcmcia card using ndiswrapper. I'm sure that works, as with the command "iwlist wlan0 scan" gives me back
the list of detected wireless networks. At this point I was wondering: is there a way to detect the new interface (wlan0) with network manager? Even after enabling the wifi card the network manager gnome applet always finds only eth0.

I've been in a difficult situation since we're having only wifi and there is no way to connect my laptop to the internet via a LAN cable.
Debian's packages don't support my wireless card. However this one works: [URL]
Is there any way to install this driver for the Installer to connect to the internet while installing?
I don't know what exactly to do when the Installer ask for my network driver so that I can use it.
