Ubuntu Networking :: 10.10 Wireless Connectivity Fail For Wifi?
Oct 31, 2010
I just installed Ubuntu 10.10. I was using iBall N 150M USB adapter for internet connection with Windows XP. Let me explain about the present Windows connection :
I am using an Outdoor CPE Wimax. For mobility purpose I have connected this wimax to one LAN port of ADSL+ WiFi router ( Beetel 450 TC1 ). This ADSL+wifi router reset to Factosy settings and enabled DHCP. With this setting , I am perfectly able to connect my laptop to Internet.
When I connect my USB adapter to Ubuntu , intially it detected the signal and asked for credentials. I gave the same and network established. But I am not able to browse the net. If I give [URL]..., its going to the ADSL+Wifi's diagnosis page. With Windows , [URL]... was going to the Wimax modem. After 2-3 trial and error , now Ubuntu also not able to connect to the wifi network.

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.

I am working on a project to build an embedded board with WIFI connectivity. My present status:
- I have a embedded development board TS7200 .
- It has USB and Ethernet Port.
- I am able to get port Linux on it and run program to communicate between devices and a computer using socket programming and Ethernet.
I need help in deciding how to get WIFI connectivity to the board. I guess it would mostly be using WIFI dongle? Any suggestion for a WIFI dongle?How should I get it working? Where should I look for proper reading material? I am am planning to do some basic program practice using WIFI on my laptop. How can I do that ?

I have an iphone, I am trying to get internet connectivity to that phone through wifi. I dont have a wifi router. But i do have a laptop with wifi card. I am connecting to internet via cable modem. In win7 I used to create an accesspoint and do the ics from ethernet card to share via wifi card. It used to work perfectly.
Now as I am sing ubuntu, i want to do the same. I have intalled firestarter, and shared the internet connection through wifi card(wlan0).After this I created an accesspoint using the gnome network applet. Now i can connect my ifone to ths accesspoint. But there is no internet connectivity in my fone.

As promised the finished (pretty much finished) wireless script can be downloaded here the wireless_script is a diagnostic tool for wireless issues. It will return all relevant information to help diagnose a wireless connectivity problem, return connectivity stats and attempt to fix common problems such as blocks. It comes in cli - wireless_script_1.2.sh or gui - wireless_script_zenity_1.2.sh'
Let me know any issues you have with it. My contact details are in the readme.txt (also the wireless results.txt generated by running the script includes code tags for forums - so please copy and paste the whole document when pasting on forums to enable this function)

I posted this on Launchpad under bug# 569445 and though I'm certain someone in our heroic development community will have a look at it eventually, maybe someone can help me here in the meantime, or at least provide some background info. Maybe a little reassurance that Ubuntu isn't broken for my Wifi is all I need.

Binary package hint: wireless-crda I do hope I've picked the right package for this. Investigators, feel free to email me with whatever bash commands you need me to find out more about the hardware. The problem is that wireless in Lucid is dying for me after about a minute or so, and the activity light on my netbook just flashes. The wireless monitor at the top of the screen still thinks it's connected. It's like it's out of sync or something.
This doesn't happen under Win7 on this hardware, nor does it happen to other devices in my house on the network. Also, I wasn't having this problem under Lucid Beta 1 I have an Acer Aspire (Olympic Variant) 1410 Win7 reports the adapter as Intel WiFi Link 1000 BGN The wireless router I'm using is a DLink DIR-628. The connection is OPEN.

When trying to connect to a wireless AP, neither wicd or wifi-radar are able to obtain an IP. With wicd, a string of various hex/dec characters flow by, with an eventual error. This happens with both WEP and unencrypted APs (- the hex/dec). With wifi-radar it simply fails, but not every time. NetworkManager connects with zero problems every time; though I prefer to not use NetworkManager, so please spare me of such replies. Someone please tell me why there should be only one wireless manager in Ubuntu that works? I have used wicd since before gutsy gibbon, and it always worked fine until the last two versions, Lucid, and Karmic. What is occurring in Ubuntu which over time breaks these excellent applications? I have tried this with four different wireless cards, and all suffer either identical or similar issues. Those chipsets are Broadcom, two RealTeks, and an Intel.
I really wish to emphasize that this post is not a request for a lecture on why I should use only NetworkManager, or why I should go find another distro. With something like Linux, maybe we could push a little harder, and have maybe say, two, wireless managers that actually work? I would honestly like to see more than two, but one is not enough. It baffles me a bit why new versions of Ubuntu mangle some perfectly good applications, but not others. In IT, surely networking, IP4, WEP, basic wifi technology, etc. has not changed so much that every six months whole new programs should need to be written to connect to a wireless access point. Nor should old ones need much tweaking. What's going on? With such boastings of repositories abundant and brimming with free apps, why does anyone want to make NetworkManager the only app that works?

I've been trying to use the wireless adapter that came shipped with my computer for a while now (it is NOT a USB adapter; it seems built into the computer). However, I can't seem to get it working.HP says that the driver is Lite-On USB Wireless 802.11 b/g Adaptor. I am currently connecting to the internet with my netgear USB adapter (I think the driver is something like prism_usb)

I'm running Lucid Alpha 1. Installed it about two weeks ago. Until a few days ago, the wireless networking was the best I've witnessed on any o.s. However, after last Wednesday's updates, connectivity now lags about 10-30 seconds whenever I open any web-page or access the repositories via aptitude. Granted after it gets going, it's fine. I noticed this same behavior in 9.10. I tested my XP connection and found no problems. .

I recently formatted an old Dell D600 and installed 9.10 on a single partition. It connects to my Airport just fine hardwired, but I have had no success getting the IntelPro/Wireless 2200BG card to talk wireless. I've entered the SSID and WPA2 security ID with no success.

Just recently I've been having strange connectivity problems with my wireless network. The connection has previously worked fine and haven't had any problems with it. I haven't installed anything that would have affect it as far as I know. how do I go about testing the network to see where the problem lies? I'm running Ubuntu 10.10 with a Netgear WG111v2 wireless adapter and my guess is it is some strange configuration problem or a rogue application is eating up packets because the system works fine when I boot it up into Windows.
When I try to ping my router I'll usually get something like 98% packet loss. However in the output below, the network sprang to life half way through my pings so it went up to 63%. What other tools can I try to find out what's going on?
Code:
alex@obsidian:~/dev $ ifconfig
eth0 Link encap:Ethernet HWaddr 00:1a:4d:4e:03:3f
UP BROADCAST MULTICAST MTU:1500 Metric:1

May I please have some help configuring wireless connectivity?I just moved and went from connecting to a LAN infrastructure to connecting with a wireless cable modem. The modem is dual-purpose, it has two ports, one for an Ethernet cable, and an access point for a wireless connection. The ISP is CableOne. My laptop, which I use most often, is wireless capable, and I want to use the wireless feature. The laptop is running Fedora 13 KDE, with a VirtualBox virtual drive running WinXP.
I have used NetworkManager to create a wireless connection and name it. I have also used WPA encryption for this because I don't want anybody else using my bandwidth. Moreover, I have tried no encryption and WEP, all to no avail.

I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

The problem is I have a wireless Belkin router which I can connect to, but after being connected for a few minutes the net disappears (cuts from the router) and my laptop will have to reconnect again to the router for internet to work again. After a few minutes (or seconds in some cases) the connectivity loss will happen again over an over.
How to fix this problem or some things I can try, I've tried updating to two different firmwares, two different channels and resetting the router. The biggest problem I find is that this happens on both my laptop, another laptop in the house and also my tablet PC but doesn't happen on two other laptops in the house, I've also tested with windows 7 and Ubuntu with my laptop.
My laptop wireless card is Atheros AR9285 802.11b/g/n WiFi Adapter

I have just upgraded to 10.04 and can't get wireless connectivity because the STA driver for bcm4312 fails to activate. Does this sound familiar to anyone? I had had similar problems in 9.10 and tried to install bcmwl-kernel-source which apparently caused errors in the upgrade process. Not sure if this is part of the problem.

I connected to internet via a USB wireless card, it works OK in GNOME, but it can't be detected on KDE. When enter KDE, iwconfig can not find any wlan. Wireless network connection not configured caused no wireless AP available, so the network not available. After I configured the wireless connection, The problem fixed. I'm replying in KDE now.

I got ubuntu working fine on my netbook and wanted to play around with opensuse. I have it installed and everything works fine except my wireless connection. I have updated everything since the installation through a wired connection, that didn't help. I have read the stickies, but to be honest, I'm so new to this stuff I'm kinda lost. So my wireless network has a WEP encryption and I have entered that password as a 64 HEX Key in the Wireless Manager widget. It connects to the network and says is labeled as active, however there is still the yellow exclamation shield next to the connection. Firefox and other apps don't have access to the internet.

I'm using 11.2 with KDE.
I can connect to the Internet on my WLAN just fine (using Opera) and can dload torrent files (using the same).
However, I have had trouble accessing some community repositories in the past, cannot synchronise with an NTP server (annoying since my battery is low and time and date are reset most reboots) and cannot use the lyrics function or Wikipedia function in Amarok. Nor can I connect to the net using Firefox (though conqueror works just fine...) I cannot download torrents on KTorrent either.
It seems that there is some sort of 'permission'/connectivity issue.

Camangi WebStation (android pen tablet)
Incredibly poor Wifi connectivity (No WPA, not even WEP full support), missing ether plug. Easy to freeze. Poor input method. Considerable pricing. poor applications. (not android-market compatible) not well organized web pages.
My impression: You have a right to buy. It is up to you, if you want to. It is your responsibility.

I have an older Gateway with model number: 4024GZ, and I just installed Ubuntu on it and I am not able to connect to my home's wireless network. I am assuming that this is because of a driver issue, whether there is none or the old driver isn't compatible. So is there a website that I can go to to maybe find a driver that will work with both my wireless card and ubuntu? My wirless network adapter is internal and is a Broadcomm I believe. (btw I am a beginner here and if I have posted this in the wrong section,

Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused.
Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.
Using lshw I found this reference to wireless
I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.

Upgraded broadband service yesterday and now using a combined router and modem (Virgin Media Hub). But I now have no wired or wifi internet connectivity on either of my ubuntu 10.10 systems. I tested it on my work laptop which uses Window and it works fine for wired and wifi.
With 10.10 I no longer have a network icon upper right panel to check, so not sure how to set up wireless. Both machines have static IP addresses and are able to ping each other but there is no internet connection on either.

I just purchased a RALINK WIRELESS G PCMCIA WIFI CARD VISTA/LINUX (UBUNTU).
It is supposed to be UBUNTU plug and play out of the box with no driver downloads needed.
I installed it but could not find a way to search the active Wi-Fi networks available like on my Actiontec card on windows xp. The wireless router/ethernet I have is an Actiontec setup for Qwest-DSL and Actiontec is the name of the wireless network.
Strangely I tried to choose setup a "new network" and entered Actiontec as the network name and it found the network and said it was connected to it. However the internet still is not working?
