Ubuntu Networking :: WiFi Stopped Working Entirely (Intel 5300 AGN)?

Oct 11, 2010

Since I originally started using Ubuntu (10.04) I have had problems with my wireless card. Now I have updated to 10.10 and it has stopped working entirely. I am using a "Dell Vostro 1520" with an "Intel(R) WiFi Link 5300 AGN" wireless card.Here are the details: 10.04

In this distribution version, if I had the wireless switch on my laptop activated at startup my wireless card would refuse to activate. There is a light to show when it is activated and this was off, but I checked anyway and wireless capabilities don't work when it is in this state. It didn't even resolve the problem when I switched it off and on again (although this caused the wireless indicator to blink on for less than a second when switched on).This was manageable because I found two workarounds:

1. Wait until my laptop had logged into Ubuntu, then activate the wireless card which would start and work as it should.

2. If I had already logged into Ubuntu I could put my computer on standby, switch off the card, come out of standby and reactivate the card while Ubuntu was running.As I said, this was completely manageable, and I got used to it. 10.10

Now that I have upgraded to 10.10 all workarounds fail, I can't use a wireless connection in Ubuntu, as my card won't activate, I cant even get the light to blink as I could before. The only way I can use WiFi is by switching to Windows.I tend to use Ubuntu for my university programming work.

Ubuntu Networking :: Wireless Stopped Working On 9.10 (Intel WiFi Link 5100)

Mar 10, 2010

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.

When I boot in Windows, wifi works fine.

Code:
tijl@Smaug:~$ sudo lshw -C network

OpenSUSE Wireless :: Intel PRO/Wireless 5300 AGN Stopped Working For 11.2?

Jun 6, 2010

The wireless on my 64-bit openSUSE-11.2 installed on my Dell Studio 1537 laptop stopped working some time back (possibly more than a one or two months back). I just discovered this last week when on business. I have not used the wireless under openSUSE-11.2 for a while so I am not certain what broke it, but I am suspicious of an update. I note openSUSE-11.3 milestone-7 works great with the wireless (on a liveCD). I note possibly two related threads, although I note no failed request for firmware in my case:request for firmware file 'iwlwifi-5000-2.ucode' failed [INTEL 5300 AGN] [OPENSUSE 11.2] - openSUSE Forums, and I see another thread here: Suddenly No Wireless Network Card - openSUSE Forums... but I can not tell if what I have is the same problem, so I did not add to those threads. In my case I can scan for the network, and see the SSID. An ip address is assigned. But a ping does not work.

Some details, the wireless is:

Code:

04:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235]
Subsystem: Intel Corporation Device [8086:1121]
Kernel driver in use: iwlagn
In terms of installed apps:

Code:

rpm -qa '*wireless*'
wireless-tools-30.pre8-5.1.x86_64
wireless-regdb-2009.09.08-2.2.noarch

[code]....

I know the router wireless network is good, because I can connect to the router via wireless with another laptop (old Fujitsu-Siemens Amilo 7400M with older Intel wireless), and the router wireless also works with this Dell Studio 1537 PC (with same hardware) but with openSUSE-11.3 milestone7 version.

Ubuntu Networking :: Intel Corp. Wifi Link 5300/Karmic 64b/ThinkPad W700: OS Restart 2 Reconnect

Oct 7, 2010

I have an IBM ThinkPad W700 running 64 bit Ubuntu 9.10 Karmic Koala. At the office I normally connect it to the Ethernet since it's never connected very reliably to the wifi there (drops out 2 or 3 times per day, usually at the worst possible time, of course), but it always worked just fine with Netgear WGR614v5 at home... until a week or two ago.

I used to be able to come home, take the laptop out of suspend mode, and it would connect to the wifi. Occasionally there'd be some hitch and I'd have to restart the network manager (sudo /etc/init.d/network-manager restart) but this was only sometimes, and when I did, it'd always work. But now, when I get home from work, I need to restart the entire system to get it to connect properly again. Without restarting the whole system, it either doesn't scan for wifi networks, it doesn't find any wifi networks, it keeps stuffing up my wifi password, or it connects and gets 0% signal.

Presumably, some driver was updated recently and it doesn't work so well. What's the easiest way to find out what drivers have been updated lately, and revert to a previous version? And what else can I try restarting so I don't have to restart the entire system? I've tried /etc/init.d/network-manager restart, /etc/init.d/networking restart, /etc/init.d/network-interface restart, and restart network-manager. I've also tried turning the wireless switch at the front of the laptop off and on, many times.

Code:
$ lspci -nn
[...]
03:00.0 Network controller [0280]: Intel Corporation Wireless Wifi Link 5300 [8086:4236]
[...]
$ ifconfig wlan0

[Code]...

The info above is when I've taken my laptop out of suspend mode and it won't connect to the network. lsmod doesn't say anything about wifi nor wireless; iwlist does see my network, which my older Januty laptop is connected to without drama.

Ubuntu Networking :: Intel 5300 Wireless Stops Working After Downloading 100 Megs?

Sep 9, 2010

I have a Dell E6500 with and Intel 5300 wireless agn card running Lucid x64. Wireless works fine and speeds are great except when I download with either the browser or thru a torrent or even updates. Once I get to around 100 megs in to the file wireless stops working and the only way to get it working again is to disconnect and reconnect to the AP. I have installed the back ports and tried several other fixed to get this to work but nothing has helped. One more note this happens on 2 other wireless routers that I have tried so I know that it's not limited to my Linksys.

Fedora Hardware :: F13 WIFI Intel 5300 Crash With Kernel?

May 30, 2010

I just install F13 yesterday, before that I use F12 and it works well with no problem. The biggest and only problem I have with F13 is wifi network. If I turn on wifi switch before OS start, WIFI LED lights and wireless works. Then I try to turn off switch and turn on again, but the LED doesnt light any more, so wireless is also silent. The bad thing is there are many notifications of kernel crash.

Ubuntu Networking :: Intel 5300 On Dell M6400 (10.10)

Nov 21, 2010

I swapped the wireless card in my m6400 from a Dell 1510 (Broadcom) to an Intel 5300 and I am trying to get it working. Right now it's not coming up at all. This is a running install of Ubuntu, not a new install, prior to the HW swap the Broadcom worked OK. I've searched all over, but nothing seems to address the specific problem of getting this started.

The laptop is a Dell m6400 with T9800 CPU and 4GB of RAM running 10.10 (2.6.35-22-generic x86_64).

Ubuntu Networking :: Intel Centrino Wireless-N Card Stopped Working?

Feb 23, 2011

I have a new Thinkpad t510 laptop with an intel centrino wireless N card (no bluetooth). I installed ubuntu a couple weeks ago after I got another hard drive in the expansion bay. I have the drive partitioned into two sections, 250gb for file storage, and 250gb for the linux OS. Currently no other OS is installed on the other harddrive.

I have had everything perfect for the past couple weeks, but once i installed some updates today, my wireless fails to work now. Just some general info that you might ask me, lspci | grep Network, returns

00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Furthermore, on the top right of my screen, my wireless is grey'd out and says no network devices available on hover.

[Code]...

Im trying to connect to my college wireless network. I have looked a thinkwiki and no one has posted any bugs. Any ideas on getting it working again?

Ubuntu Networking :: Intel Pro / Wireless 3945ABG Stopped Working - Solve This?

Aug 11, 2011

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.

In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.

I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

Ubuntu Networking :: Wifi Stopped Working After Update / What To Do?

Jul 3, 2010

I've been running ubuntu on my Asus 1001ha netbook for half a year or so. I ran Karmic for at while, wifi working and all, accepted the recommended updates when Update Manager popped up and everything was fine until one day I let Update Manager do it's thing and my wifi stopped working.. Lycid had just come out that same week, so I thought "screw it" and installed 10.04 instead..

So I've been running 10.04 for a couple of months now, everything working fine, including the wifi - until today.. Update Manager suggested some upgrades, I accepted and *pouf* my wifi is gone again..

That's the second time Update Manager knocks out my wifi, any way to roll back todays update or how to the the wifi working again?

Ubuntu Networking :: Wifi Stopped Working After Install?

Oct 11, 2010

I have a laptop that was working fine with 10.04 LTS. Today, I did a full 10.10 install and now my wireless is not working. Thinking it had to do with 10.10, I did a full install back to 10.04 LTs. Wireless is still not working. I tried installing the driver for my laptop's internal wifi using ndiswrapper, but that didn't work either. I have another laptop that is identical to the non-working one, with the exception that it is running a Celeron processor and non-Nvidia graphics. Otherwise, they are identical with respect to the wifi adapter. The Celeron machine is giving me absolutely no problems.

Ubuntu Networking :: Intel 4965 AGN Wireless On Asus F3SV Stopped Working (10.4)?

Oct 23, 2010

My wireless worked out of the box for the past few months. When I was running low on battery recently, I put the laptop to sleep. When I woke it up, there was a black screen with a flashing underscore. I pressed a bunch of buttons but nothing happened. Then suddenly it said something about a wireless hardware error and I did a hard reset by holding down the power button. When I turned the computer back on, wireless was greyed out. There's no hardware switch to enable and disable wireless and the software switch had no effect. I tried echoing into the 'state' of the adapter but it didn't let me. When I tried sudo ifconfig wlan0 up it gave me the following error:

Code:

SIOCSIFFLAGS: Unknown error 132

Ubuntu Networking :: Wifi Worked For A While Then Stopped Working - Can't Get Online

Jun 18, 2011

I had 10.10, and all was well. Then I installed natty, and WiFi worked for a while, then stopped working. I later went back to 10.10, and WiFi still isn't working. The WiFi icon in the top bar looks like it's scanning. But it just keeps on scanning, continuously. Then it asks me for the password, so it obviously connects to something if it knows the network needs a password.

But here's the weird thing, my router also creates a BT Open Network, which I think is some pay service that BT offer, apparently through anyone's wifi since it's not password protected. I can connect to that. But not the actual network that leads to the internet. This happened a while back, and of course I can't install any updates on it because I can't get online. I am writing this from XP on the same computer, and XP can connect to the network no problem.

Ubuntu Networking :: Wireless Stopped Working On Thinkpad X201 (Intel Centrino 1000 N)?

Feb 18, 2011

I have Ubuntu 10.10 on a thinkpad X201. Wireless was working, but has stopped. It still works in windows, so it is not a hardware problem. iwlist wlan0 scan sees the available networks, but I cannot associate with any of them, including my own.

Last night was my first attempt to connect to a secured network, and nm-applet failed to make the connection even after entering the WEP encryption key and SSID. By turning networking off in nm-applet I was able to manually bring up the connection by editing /etc/network/interfaces and using ifup wlan0. (nm-applet seemed to be interfering as long as networking was turned on there.) Wireless was working perfectly until I rebooted. Now I can't get it to work at all. (There were some partially completed security updates which completed when I rebooted. I hope this wasn't the cause of the breakdown.)I notice that wpa_supplicant is always running. I tried killing it in case it might be interfering with the connection process, but something keeps restarting it.

Ubuntu Networking :: HP EliteBook 8730w/ Intel Ultimate 5300 Network - Grep 'Wireless Brand'Does Not Show Anything

Jan 21, 2011

Ive installed Ubuntu recently but none of my attempts to get the wifi network working were successfull. It establishes connection but the indicator shows no signal and I cant connect to any website, I tried pinging external IPs etc. None of these worked. lspci -nn | grep 'Wireless Brand'Does not show anything. I could find 03:00:0 Network Controller: Intel Corporation Ultimate N WiFi Link 5300 lsmod | grep "wlan_module_name"Doesnt show anything. Restarting network says only: *Reconfiguring network interfaces... Kernel boot messages:

The network Im trying to connect to is hidden, so I have to input SSID manually, I doubt this causes the problem.

Ubuntu Networking :: Wireless Stops Working With Multiple Intel 5100 (vaio) On Wifi

Nov 24, 2010

I'm using a Vaio TT, which seems to use an Intel 5100 WiFi chipset, and a Linksys WRT54G2 (firmwares 1.0.1 and 1.0.4), ubuntus 10.10 and 10.04.

Wifi works fine out of the box. However if the other vaio tt in our office (running windows 7) comes online, my laptop stops being able to make new connections. It WILL stay connected to chat servers, and downloads SOMETIMES continue to work. However all new HTTP requests / ssh connections / rdp connections / pings fail. The laptop still appears to be "connected" to the wifi network.

This may also happen after an undetermined amount of time without the extra vaio. It is not solved by reconnecting or rebooting. Once the extra vaio leaves the building, everything works fine again. This problem does not happen at all if I boot into windows.

Ubuntu Networking :: Intel WiMAX/WiFi Link 6050 Wireless Card Not Working?

Dec 14, 2010

I'm dual booting windows 7 64 bit and Ubuntu 10.1 64 bit on my Dell Inspiron 11z with an embedded WiMAX/WiFi Link 6050 series wireless card made from Intel. I only use it for wifi, not 3g or wimax. I installed the latest driver from intellinuxwireless.org, iwlwifi-6050-ucode-41.28.5.1, but it still doesn't seem to work. I ran these terminal commands from another thread:

cd Desktop/wlwifi-6050-ucode-9.201.4.1
sudo cp iwlwifi-6050-4.ucode /lib/firmware
sudo chmod 644 /lib/firmware/iwlwifi*

After running "sudo rmmod -f iwlagn sudo modprobe iwlagn", I get this read out for my wireless card.

In the ubuntu help section it tells me to flip a manual wifi switch to enable it, but pressing my windows wifi button, F2, doesn't appear to do anything while in ubuntu. The only experience I have working with linux is typing some terminal commands on my android phone to root it.

Ubuntu Networking :: Intel 5100 WiFi Card - Dell Latitude E6400 - Suddenly WiFi LED On The Computer Stops Blinking

May 4, 2011

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.

What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.

On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
