Bug Description

HP Pavilion laptop with Ralink RT5390 wireless interface

1. Can detect home wi-fi signal but can't connect. Keeps asking for password then "disconnects" over and over again.

2. All other computers, tablets, and smartphones at home can connect to the wi-fi without any trouble at all.

3. HP Pavilion laptop can connect to the internet if tethered to my smartphone (used as a portable wi-fi hotspot).

RAlink RT5390 Wireless 802.11n 1T/1R PCIe in a Compaq Presario CQ56. It had Windows 7 on it orginally. The wireless worked fine. I installed Kubuntu 12.10 amd64 and it still worked fine. The OS offered to upgrade to 13.04 and I let it. That's when the wireless quit working right.

It connects fine if the computer is within 2 or 3 feet of the wireless router. Any further than that and it loses the connection. It can see the network but won't get an IP address.

I've tried the offical drivers http://www.mediatek.com/_en/07_downl...il.php?sn=5001 , but I get build error and is unable to continue.

Ndiswrapper 1.58 from http://sourceforge.net/projects/ndiswrapper/ , module loads but I get a "loadndisdriver: load_driver(364): couldn't load driver netr28x." error

compate-wireless gives me the same build error as the official driver,

I tried using kernel 3.9. Still the same problems. Also: The wifi disable/enable button does not work.

The only way I can get it to work reliably is to use the 3.5 kernel that came with ubuntu 12.10. It works fine with this kernel, and so does the wifi disable/enable button. Weird. Aren't new kernels supposed to improve, not degrade existing functionality?

However, It did not fix my issue with the wif enable/disable button. I cannot use the button to turn the wifi on or off. It's one of those function key buttons. -- It all works fine, if I use the 3.5 kernel from Ubuntu 12.10 though.

If I follow the procedure in #14, I can build the driver, but when I

sudo modprobe -r rt2800pci

my connection goes down as expected. I then

modprobe rt5390sta

and I get nothing...wireless does not even come up.

I also have the problem with the wifi enable/disable button. I cannot use the button to turn the wifi on or off. It's one of those function key buttons (F12).

I have the same (or similar) problem with my Acer Aspire one D270-1895. The problem started shortly after upgrading to XUbuntu 13.04 (not the initial upgrade, but one or two updates after that) and has continued through all updates since. Since where I am now located I cannot conveniently report this bug from the LINUX on my system, I am doing so from the Windows partition so cannot see which version of the kernel, but it is the one included in the latest updates -- I think it is 3.9. I can connect to non-secure networks without problems, and I have successfully connected to WPA networks, but cannot do so if the connection is to networks using WEP. Since I use this computer while travelling and trying to connect at the homes of friends or relatives, I cannot change anything in the router.

I am hoping that this bug will be fixed soon so that I do not have to resort to booting in Windows in order to connect to the internet!!!!

I had the same problem. The driver seems to be a bit fickle in what it doesn't like. I was able to get it to connect periodically by changing channels and going back and forth from N to G. I don't know much about drivers but perhaps this was causing the drive to reload? If you don't have a Ethernet cable handy I'd try restarting your router with a few different settings to get it (the card) to connect long enough to apply a fix.

I was able to resolve the issues by installing an unstable build of [firmware-ralink](http://packages.debian.org/sid/firmware-ralink)

Note: If you are reading this in the far off future the updated firmware will probably be available in the [linux-firmware ppa](https://launchpad.net/ubuntu/+source/linux-firmware). I'd check there before following my solution. At the time of this writing it was at *1.106* which did not contain the fixed ralink firmware

Here are the steps I went through;

1. Added "deb http://http.us.debian.org/debian unstable main contrib non-free"
to my apt sources (/etc/apt/sources.list)

I just wanted the deb file for firmware-ralink but I was too lazy to google and figure out how to pull the deb directly. You will need to make sure you REMOVE this line from your sources.list immediately after installing or you risk conflicting packages in the future. There is nothing worse than a conflicting kernel update.

2. Ran
 $ sudo apt-get update
 $ sudo apt-get -t unstable install firmware-ralink

3. At this point I got an error

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

4. So I forced the install by running:

$ sudo dpkg --force overwrite -i /var/cache/apt/archives/firmware-ralink_0.39_all.deb

5. After that I removed the line from sources.list and ran $ sudo apt-get update to clear the cache of
debian packages.

Everything seems resolved now.

Is there any estimate as to when this bug might be assigned to someone and to get it fixed? My netbook has been unusable as a portable device anywhere that the WiFi link is secure (works fine in lots of airports with free access and in many hotels). This is the kind of problem that will deter the average user from adopting LINUX in general and Ubuntu in particular.

ojc (ocrawford) wrote :

Re my own comment #27
I've got this working by changing my wireless network to unsecured. It connected. I then returned the wireless to secured and it's worked fine since. That's just a couple of hours so I'll see how it goes. Throughout this fiasco my XP desktop and Android phone have behaved perfectly.

I don't know if I'll have the problem on other wireless networks though.

twakatpw (tpwmisc) wrote :

Seems there's a sudden revival of interest in this problem - and alpha 1's comment (#28) really chimes with me (I'm a web designer up through sass to php). After about a year wondering whether to try Linux on an NC10 Samsung netbook because Microsoft are abandoning support for Windows XP, I finally wiped the hard drive after USB-booting with several distros - with wifi fine on both live and persistence sessions.
But I cannot now, after a full install and one whole, wasted day of trying every suggested MAC trick, driver quest and manual config, get a wifi connection - I can piggy-back unsecured networks but, so what? I could do that with Windows.
I was happy to spend time delving through a (largely undocumented) Linux new world but if it can't get a simple wifi connection sorted without a computer studies then it's overrated. Like alpha 1 I'm left with an unusable netbook (I'll buy a non-Linux tablet instead) and wondering if Windows didn't at least get one thing right.

ojc (ocrawford) wrote :

Re #28.

The computer's been asleep overnight. When it woke up it had the same symptoms. Repeated password requests and no connection.

I used my smartphone to change the wireless on my TP-Link_42DE2E to Open. The Ubuntu machine connected. I then reverted the wireless to WPA2-Personal. I went to Edit Connections and deleted both TP-Link_42DE2E instances. I restarted the Ubuntu machine and attempted to connect to TP-Link_42DE2E . This time it connected.

Next time it happens I'm going to try just deleting the TP-Link_42DE2E without changing the network type to open.

This is a new problem for me. I've been with Ubuntu since 2009. I've had 13.04 since April and it's just started being a problem.
I don't know it any of this is any help to anyone. I'd like to think there's someone working on this. There appear to be a number of similar threads about it. It's a deal breaker for anyone. Wireless connection just has to work.

Re #27 A few days on and the Ubuntu machine is still connecting when it reawakes.

alpha1 (wmstrome) wrote :

I just "upgraded" from XUbuntu 13.04 to 13.10 Beta and now the wireless works with my encrypted router (WEP). The kernel is now 3.11.0-04generic

I have rebooted a few times, and the wireless connection has worked immediately for me without having to re-enter the key.

The update went very smoothly, and a few other minor problems that I experienced with 12.04, 12.10 and 13.04 have also disappeared now.

Canonical does not advise installing 13.04 Beta on a production system. However, I normally use this computer only when travelling, and I have no trips planned for a few months, so I decided to try it. There are a LOT of programs that have to be reloaded, but other than that, so far, it looks great.

HP pavillion g6 laptop, pre-installed windows 8 with dual boot Linux Mint 15, originally with kernel
Wireless works fine with good signal strength but drops out, requests new sign ins with weaker signal (works OK and reliably if booted in windows8)

Tried installing driver & patch as per #14 - still drops out
Adding blacklisting rt2800pci in etc/modprobe.d/blacklist.conf, as suggested in various forums, causes total wireless failure

Upgrading to kernel - still get drop outs, no improvement

My situation is similar, with an HP 2000 Notebook. However, Ive been able to connect to the router just fine, but have very intermittent speeds, ranging to 0k to maybe 5k, when I have a 1MB line. I piggyback via ethernet from my System76, and get a perfect signal on that notebook and perfect speed on the HP. I don't wanna delve into adding patches that are gonna be borked every kernel update, as this notebook doesent belong to me, not to mention I don't have all that much time to further break this thing. I'll try the prop. drivers and see if any improvement. It seems to me that there are various fixes and hexes for this issue, but not a universal fix.

I had similar problem just after upgrading to ubuntu 13.10, and recent update in ubuntu, which upgraded kernel used to 3.11.0-15, solved this issue for me.

I know this is an old thread, but it seem this problem still exists on Ubuntu 14.04. I recently did an install on an affected computer and I documented the process so I could make this instruction for the benefit of anyone else having the same issue:
This repo also contains the driver itself, as it seems Ralink/Mediatek keeps moving it around so some users have trouble finding it.

I am new to Ubuntu and recently put in Ubuntu 14.04 LTS into my Lenovo Ideapad yoga 13 ultrabook. Installation went fine but for some reason I was not able to detect wifi. I already had windows 8 on the ultra book and wifi worked fine on windows.
I was able to solve the issue after updating the kernel to 3.14.4 .

Following this I dowloaded the driver files for realtek rtl8723ae-bt wifi card. (here is the link: http://www.mediafire.com/download/sanq19s3vv1d9c9/RTL8723AS-VAU+linux+driver.zip)

Then I found this really useful video on youtube which gives a step by step explanation as to how we can install these driver files.
(link: https://www.youtube.com/watch?v=H3WdsSHo5Sw)


Would rather prefer the ubuntu software coming with the 3.14.4 kernel as default. Such issues will only aid in discouraging new users from trying out the software

I recently installed Lubuntu 14.04 LTS in my HP Mini -110-3500 Netbook.
I was able to set nm-applet for startup & it detects a very strong signal of my home wi-fi [D-Link].
It prompts me to enter password but irrespective of correct or wrong password I enter it fails to connect and keep asking for password again and again. Though ethernet through same router works well.

PS: I had earlier worked on Ubuntu 12.04 LTS, but then I didn't had any wi-fi router.

Wi-Fi association issues are very baffling. Perhaps it's simply me, however, they ordinarily occur at the very least conceivable time, when you have to check something on the web, compose an imperative email, et cetera. In case you're having issues associating your Android cell phone to a Wi-Fi organize, you're not the only one. This is a typical issue that, lamentably, plenty of clients encounter every now and then. In this post, we'll investigate a couple of fixes that could very well settle your availability issue and get you back on the web if your telephone won't interface with Wi-Fi. How about we make a plunge.

Jack Richer (richerjack660) wrote :

In reality, it is a typical issue with Broadcom arrange connectors in Ubuntu. An alleviation is that Ubuntu gives extra drivers explicitly to Broadcom connectors. Be that as it may, the issue is that to introduce extra drivers in Ubuntu you will require a system association. On the off chance that you have a wired association, it will be anything but difficult to introduce the extra drivers. Yet, in the event that you are limited to the remote system just, you'll need to search for exchange techniques.

A standout amongst the most well-known issues looked in the wake of introducing Ubuntu is the system issue. A few times you will have no remote system in Ubuntu and a few times moderate remote association and at some point it will change among quick and moderate. On the off chance that you are fortunate, it could be fixed by introducing legitimacy drivers in Ubuntu however for the most part, you will be left raging, reviling over moderate or no WiFi association.
