Ubuntu Networking :: Wifi Adapter Is Not Detected?
Feb 19, 2011
I just installed ubuntu (latest version). Everything worked except when i plug the wifi adapter to the computer nothing happens... It wont show up for wireless network... What do i do? This adapter works great on xp, and its a ralink wifi adapter. I dont know which model version i have though because i bought it new on ebay and it never said model info... I also have a netgear wg111t, how would i get this to work as well?

I have just started to work on Ubuntu (Ubuntu 10.4 LTS) and I am having some problems to get a WUSB600N vers. 2 802.11n adapter working. I have followed the procedure described at [URL] . The compilation has been successful and I can see the kernel loaded an the module detected:
Code:
adrien@ubuntu:/$ lsmod | grep rt3572
rt3572sta 612272 1
adrien@ubuntu:/$ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[code]....
The wireless adapter is detected by the system and it can scan the neighboring APs (cf. below with MAC address made unreadable):
Code:
adrien@ubuntu:/$ sudo iwlist ra0 scan
[sudo] password for adrien:
ra0 Scan completed :
Cell 01 - Address: --:--:--:--:--:--:--

I want to change to Debian from Ubuntu. But, unfortrantly, I have problem in installation.I want to install Debian 5 on my Dell optiplex 380 desktop. In the process of installation, the networking adapter can no be detected. My networking adapter is Broadcom Corporation netlink BCM57780 Gigabit Ethernet PCIe. It seems like that Debian 5 does not have the driver for this kind of adapter.What can I do now

Been using Ubuntu for 1 yr now on my Dell Dimension 8250 but a newbie with my Averatec AV3270-EH1 laptop circa 2005. Ubuntu 10.04 does not detect the Integrated WLAN card/adapter. I've looked at all the forums/posts but none had the issue I have. When I type lspci into the terminal i get this back:
00:00.0 Host bridge: VIA Technologies, Inc. K8M800 Host Bridge
00:00.1 Host bridge: VIA Technologies, Inc. K8M800 Host Bridge
00:00.2 Host bridge: VIA Technologies, Inc. K8M800 Host Bridge
[code]....
And when I type in iwconfig:
lo no wireless extensions.
eth0 no wireless extensions.

I started yesterday off wanting to install this USB wifi adapter on my PC (which is mini-itx so has additional pci slots) [URL] it has the Ralink 3070 chipset. I tried everything I found when googling, nothing came close to working, this was in Fedora12. So I gave up and installed Ununtu 10.04, hoping for better luck there. Ubuntu will recognise the presence of a wifi adapter, here's the output from iwconfig
[Code]....
But it sees no wifi networks and generally won't do anything; I don't think it has the right driver. Rosewill does list a (linux) driver and so does Ralink, but again, neither of these come close to working. has anyone gotten this adapter or chipset to work in ubuntu?

My laptop has an internal wireless g "adapter" (for lack of a better word) and I plugged in a very cheap and very small ASUS wireless N adapter later on. The ASUS adapter has better bandwidth (again for lack of a better word) but isn't as high quality of a link as the internal adapter is.The laptop appears to be using the internal adapter, but i want it to use the ASUS adapter.

I've just upgraded my old laptop from xubuntu to ubuntu 10.10 and I have some connectivity problems with my usb adapter Netgear WG111v3. On xubuntu I had no problems with connecting on the network but with ubuntu, it says I have good reception but it doesn't connect on the network (rarely it does, but for a very short time). I have another laptop currently running on ubuntu 10.04 and it has no problems at all (however it has an internal usb card).

HPG62-144DX notebook, Windows 7 and considering Ubuntu. I installed 10.10 and tried to get my wifi running but that wouldn't work. I had a connection only sometimes and it broke up after 5 minutes. Once I got a webpage but annoyingly slooow. Got the advice to update drivers and stuff. But the wifi connection is the only one I have...
Went back to 10.4 32-bit. Booted from CD and will keep it that way until this is sorted out. Now I see my wifi hotspots directly and I have no problem to establish a connection. The icon shows 3 bars quality. Network Tools says: Wlan1 = Realtek, Transmitted bytes xxx Received bytes yyy, no errors, link speed = 1Mbps, State = active. Looks good!
The only minor thing here is that enabling/disabling my internal Atheros antanna also enables/disables my Alfa USB Wifi adapter (based on Realtek 8187) but who cares. A bigger problem is: when I start Firefox it doesn't come up with a webpage. It just keeps on saying: "loading". At the bottom of the screen it keeps saying "Looking up" for ages. Nothing further.

Okay I've got a Netgear N-150 WNA 1100 USB WiFi adapter, it doesn't work in Ubuntu it's not supported. There should be a way to make it work with ndiswrapper. I tried and failed before and due to other non related circumstances I had to reinstall Ubuntu. What are the steps to install ndiswrapper and it's dependency's on a fresh Ubuntu installation that cannot connect to the internet.

My laptop has an internal wifi adapter, but I recently purchased another one because of its extended range.susb, shows that the new adapter is:
Code:

After disconnecting my internal adapter from the wireless network, I can scan for networks

After a new fresh-from-DVD install of Fedora 14 64-bit (over top of Fedora 12 64-bit which went over top of Fedora 10 64-bit before that) my Linksys WUSB600N adapter connects at login to my WiFi N router with WPA2 Personal.
That is great, as previously (fc10/12) I had to use the Ralink drivers per ogetbilo's thread on this forum (that thread kept me on the net for many years now). And at some point this even became a pain because sometimes the system would boot and refuse to connect to the wireless (which would hang trying to connect) and then crash to a dump screen on shutdown (bug reported). The fix was hoped to be found in upgrading to F14 and the newer kernels with working native Ralink chip support.
But I still have an issue... the connection stays up for a few minutes then drops. If I disable/re-enable wireless it (at least sometimes) re-connects. But obviously that is not workable. This is a USB adapter and I am not entirely sure that there is not some USB powersave issue going on, but I do not see anywhere to disable system USB power saving either.

i have a broadcom BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) wireless adapter on a dell 1501 run by ubuntu 10.10.this particular model and revision is suppose to be absolutely supported by linux and indeed it did work perfectly before the user ran a upgrade from ubuntu 10.10 to 11.04.subsequently i have reinstalled 10.10. as i recall when i installed ubuntu 10.10 the first time i simply ran the System>Admin>Additional Driver installation tool to make the wireless work. i cannot recall if i ran the b43 or the sta driver but i have tried both this time and had no luck.
i am aware that the broadcom adapters are notoriously troublesome and i have tried the two workarounds here URL... as well as their third alternate workaround with no success.

I just installed Fedora 14 i386, and Fedora can see the wireless network just fine. I try to connect and nothing happens. It asks for the PSK constantly (yes, I promise I'm entering it correctly), even after I enter it correctly (I guarantee). I've searched around here a bit, but due to my limited knowledge in linux system I can't figure it out

Code:

Code:

I got two issues with my wifi usb adapter:
1) it cannot see any networks around
2) i cannot setup it in master mode to use my PC as a router
As far as i can see, the device is recognized and the correct driver (rt73usb) is loaded. I was able to connect to a laptop somehow (the laptop could see other networks and the adapter's PC-to-PC network). I'd like to make it work as a router, i.e. share my internet connection (eth0) via wlan0. Here is what i have:
Code:
Ubuntu 10.04
Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux
TP-Link TL-WN321G wifi usb adapter as seen as
Bus 001 Device 006: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter
$ iwconfig wlan0

I have a USB WiFi adapter that my Ubuntu desktop install (10.10) automatically detects, and it works great. I just used the alternate installer to set up an old box as a server, and it doesn't install the driver for the adapter. lsusb finds the adapter, but I don't get a wlan* listed in /dev/. how I can determine what module(s) are used to run this adapter on the desktop so I can load them on the older box? Or is there some package I should install from the CD to help auto-detect the adapter?

I have just installed the last FC distro, and everything works good, except the wireless network.I have a Linksys N-Ultra WirelessN USB wifi card, model WUSB600N.It uses the rt2x00 driver, concretely the rt2870 driver (at least, thats the driver included in the original device drivers CD).Right now, the problem is that i don't know how to make my Fedora 12 to enable and/or connect to internet.

I have just installed Fedora 14 on my desktop machine and have just discovered that it can't detect my WiFi card. The card is an Edimax EW-7711In which the makers say will run with Linux. I know that the card works fine with Ubuntu because my brother uses the same card in his Ubuntu machine but he is away until after Christmas so I don't know what he did to make it work other than I know he used ndiswrapper and the Windows drivers that were supplied with the card. I have looked for ndiswrapper in the Fedora repositories but it doesn't appear to be there.

I have a problem with my BROADCOM BCM4311 802.11b/g WLAN... I made a clean installation of Maverick Meerkat and everything runs perfect except the card drivers... then I investigated almost a week on the net and finally the problem was solved (I made the installation of some drivers on Synaptics tool, then I wrote some codes on the Terminal to activate the light to turn it blue and the Wi-Fi IS ON AND WORKS!).
I thought everything was ok, but when I restarted the laptop, the wifi conections aren't able to be detected so I must re-install the card driver to get it active again :S. I really don't know why the card drivers works only when I install them, because restarting the system make them simply don't work.
I read something about changing my user's state (it was 'personalized') to 'administrator', but nothing happened.I searched on Ubuntu's web but nothing works.It's a Compaq Presario V3000.

I've recently salvaged a computer I found gathering dust in the basement and decided I'll have it running on Fedora (I have a summer studentship coming up that needs Linux use so I thought I'd best start learning!). Following a clean install, Fedora can see the wireless network just fine. I try to connect and nothing happens. Half of the time it will ask for the PSK (yes, I promise I'm entering it correctly) and the other half of the time it will just stop. When it does ask for the PSK I enter it (correctly) and it will ask me again... and again.

I was running 9.10 in LiveCD mode and was unable to get online. Went to System>Administration>Hardware Drives and found "Broadcom STA wireless driver". Cool. So I went ahead and installed 9.10 (dual boot with Vista), repeated above steps but found no "Broadcom STA wireless driver" option, in fact no proprietary drivers. So I still cannot connect to the Internet, and I don't know where to go from here. (Note: I installed 9.10 side by side with Vista: good? bad?)

I just installed Ubuntu 10.10 on my Dad's desktop. Everything was fine, but the usb wireless adapter is not being detected correctly. It's Zyxel G-220 (Verizon put it in instead of running a cable from the Vios box next room). I checked the website and it says it's supposed to "work out of the box".

i tried following the readme file included in the driver of the usb network adapter but seems its not exact.
any ideas on how i can configure it manually? KDE does not detect any wifi device. .(of course since no driver is installed yet).
i used my desktop (win***)with DSL connection and installed the driver of the usb net adapter.. made it as the access point. . so my laptop detects the desktop as wifi spot.
