Ubuntu Networking :: AR5001 Chipset - Wireless Networking Randomly Loses Connectivity And Can Not Regain Connectivity

Jun 25, 2011

Wife's laptop has AR5001 Wireless Adapter laptop model is Toshiba Satellite A215

Problem : Wireless networking randomly loses connectivity and can not regain connectivity, the only apparent solution is a full power down , this is not even certain to work. The card works under Windows, she hates Windows. (I love her for this) I know it's not faulty hardware , because it will work for days on end under Windows without problems.

Things I've tried : madwifi drivers (any and all versions available) : These increase stability of the signal and seem to delay the inevitable however it still happens. When using these drivers the only option is to unload them modprobe -r then reboot then remove them again and re add them. It makes no sense why this works, and if I don't remove them prior to rebooting it will not work.

ATH5K drivers : These are pretty much junk, results are unpredictable at best, sometimes it will work perfectly for a few hours, sometimes it will not work at all. Nothing is repeatable, I can't seem to force whatever condition is causing this. rfkill does not show the wifi being blocked (hard or soft), unblocking it anyway does nothing, only way to make this work and it's iffy is to fully power down wait 5-10 minutes turn it back on and it MAY decide to work.

Firmware update : Updated the Toshiba BIOS to the latest version of the firmware 2.0 no joy here either. Same issue both sets of drivers.

Tried different distros and kernels : I've tried Mint 9, 10 ,11 ; Ubuntu 10.10, 10.04 , 9.10 and 11.04 (which is currently installed) , Fedora and OpenSUSE. All are giving the same problems. I have also tried a slew of different kernels no joy from any of them (I'm not at the computer with the issue now I will post exactly what kernel versions I've used when I have access to the machine).

Another useful bit of information, the hard switch to disable/enable wifi WILL disable it but turning it back on does absolutely nothing. The hotkey does nothing at all. The bios does not have an option to disable or enable the wireless card.

I will also post the typical lsmod , lspci , iwconfig all that good stuff when I get back to the computer in question. I'm probably just going to buy a PC card for it and give up on that one, but this is driving me insane and I would really like to see it resolved even if I do replace the hardware.

Ubuntu Networking :: No Wireless Networks Being Detected

Feb 14, 2010

I have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.

I'm dual-booting Ubuntu 9.10 (upgraded from 9.04) and Windows 7 on my Dell Inspiron 1525 laptop.Ubuntu doesn't recognize any wireless network (both in 9.04 and 9.10); my Windows OS works perfectly well with wireless, as does my wired Internet connection with Ubuntu and Windows.I've had this problem on previous installations of Ubuntu (I've removed and re-installed it several times) but I can't locate the solution anywhere. I've tried numerous fixes that I've found online, but none of them have worked.System>Administration>Hardware Drivers tells me that the Broadcom STA Wireless driver is activated and currently in use

Ubuntu Networking :: Wireless Networks No Longer Detected

Jan 29, 2011

I have a msi netbook with ubuntu netbook remix installed and it was working great until yesterday when suddenly it stopped detecting my home network. There are no problems on my two other machines, so I'm sure the problem is the netbook. I have no idea how to go about troubleshooting this. I was hoping someone could help me by giving me a place to start.

Ubuntu Networking :: Wireless Networks Detected But Unable To Connect / Fix It?

Jul 27, 2011

New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.

Debian Multimedia :: Not All Wireless Networks Detected

Mar 13, 2015

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...

My wireless network is being detected but it refuses to connect to it. I am entering the accurate passcode and I have tried doing various commands for it to work, but it is being stubborn.

Also, it would help to know which WEP Index to use and type of Authentication.

Slackware :: No Wireless Networks Detected In -current After Upgrade Of Wpa_supplicant

Feb 25, 2011

I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.

I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue.

OpenSUSE Wireless :: "iwlist Wlan0 Scan" Gives Back List Of Detected Wireless Networks

Mar 21, 2011

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.

Ubuntu Networking :: AR5001 Driver - Wireless Turned Off By Hardware Switch

Jul 11, 2011

I installed 11.04 some time ago. I got my printer to work, but I have tried to use wireless and I cant. I can perfectly connect using a wired connection but on the network menu in the taskbar it tells me that wireless is turned off by hardware switch. I am suspecting that I don't have the drivers for my atheros wireless card, but when I click on additional driers it tells me that there are no drivers to download. how to configure my wireless card to work with natty?

Ubuntu Networking :: No Longer See Any Networks Under "Wireless Networks"?

Jan 7, 2010

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.

This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

OpenSUSE Wireless :: Painfully Slow Wireless Throughput On Atheros AR5001 Card

Aug 12, 2010

I have a Acer Revo R3610 nettop on which I installed oS11.3. It has an Atheros AR5001 wireless network adaptor.I'm getting very bad latency and throughput on with this card. In comparison my Thinkpad with Intel card achieves at least 10 times the throughput from the same location. Also when I boot my wifi will come up authenticate and then a few seconds later disconnect and reconnect. I've tried updating the kernel to 2.6.35 as one of the fixes was to improve the performance of the ath5k driver. I'm using wpa2 authentication.

Here are some details:

Code:

mediacentre:~ # /sbin/lspci -nnk
00:00.0 Host bridge [0600]: nVidia Corporation MCP79 Host Bridge [10de:0a82] (rev b1)
Subsystem: Acer Incorporated [ALI] Device [1025:0222]

[code]....

Is there anything else I paste that will help determine the cause of the bad throughput. Browsing the web or copying files across the network is bordering unusable.

Ubuntu Networking :: Wireless Chipset Dead ?

Jun 21, 2010

It looks like my laptop's wireless chipset (Broadcom) has/is dying. It won't work anymore on my Lucid install whereas it was working perfectly. The warrenty is long expired.

lspci brings up nothing about it anymore, it once did.

I booted my laptop into Win7 and it no longer finds it either. The manual slider switch on my HP Pavillion dv6000 is in the on position but the light is yellow.

It will very rarely work on Win7 now.

I can't afford a new laptop just now so it looks like I need an external wireless adaptor. I have (open busses) USB, cardbus/54, and a small firewire port. It does not pcmcia or other busses.

Any particular chipsets to look for or avoid?

Ubuntu Networking :: Broadcom Wireless No Longer Recognizes Wireless Networks?

Jan 11, 2010

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.

Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fianc饠after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.

I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:

Ubuntu Networking :: Pavilion Dv6 Wireless - Can't Find Local Wireless Networks

Jun 11, 2011

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

Ubuntu Networking :: Can't Connect Wireless / Ralink 3070 Chipset?

Aug 18, 2010

this is my first attempt to get into Linux (10.04 Lucid Lynx), and I'm eager to learn. The problem is however that i can't connect to the internet using my USB wifi dongle (Jensen 25150). I've tried what this link says:I've tried to blacklist rt2800usb, rt2x00lib, rt2x00usb and rt2870sta and to load "/etc/modules/rt3070sta", but no luck in that, so I simply do not know what to do next. Perhaps I haven't blacklisted them the right way? I've typed in the commands and saved Gedit and closed it. Is that the right way?

General :: Ubuntu 9.1 - Invalid RT Chipset Detected

My computer was working fine yesterday. Last night I opted to load the newest ubuntu os ver 9.1. Now all I see after the initial booting takes place is a blank screen. I have managed to look at the booting up sequence and at the end of the multiple lines of code is the message: 'Invalid RT chipset detected'. I do not know if this is significant or not.

Ubuntu Networking :: Intel Mobile Chipset 4 Series / 10.04 / HP DV6-1030us (Wireless Connection)?

May 3, 2010

Noob to Ubuntu here and I cannot access my wireless connection. It is working fine right now (wired) but I am using the TV stand as my computer desk right now so... not very practical. I tried following the "howto post a wireless issue (ticket)" but there was too much information for me to be able to put on here.

I have my SSID and my WEP. I am on Verizon DSL (only provider in my area). I tried using the wireless setting in network connections and I tried using DSL. I assumed that SSID+Password=Yay the internet works! but apparently not.

Ubuntu Networking :: Edimax EW-7128g Wireless PCI Not Working With Ralink RT2561/RT61 Chipset

Sep 5, 2010

Just installed Ubuntu Studio 10.04 and everything seems to be working nicely except I have no networking.

The card does not appear in the Network Settings GUI. The only 3 tabs I have are General, DNS, and Hosts.

A screen grab is attached.

I'm a long time Windows user trying out some of the best Linux creative apps I can find. So, Ubuntu Studio was a no brainer. I checked the manufacturer's site for linux drivers and they are available, but I don't know how current. (Edimax site, not RaLink's site.) I opened the file and it looks like it needs to be compiled and installed to work. Something I know almost nothing about. The card is listed as supported in this forum for Ubuntu 9x but I can't find information about it for 10.04

PS. I have no networking on the system but I can transfer files via USB flash drives if needed.

Some System info:

Code:

1 ) Machine Brand and Model (PC/Laptop): Dell Precision 650

2 ) Wireless Brand, Model and Wireless Chipset: 03:0c.0 Network controller: RaLink RT2561/RT61 802.11g PCI

3 ) check interface: robert@ubuntu:~$ ifconfig
