Ubuntu Networking :: Wifi: Always 100% Signal After 10.10 Upgrade (msi Wind U100)
Jan 1, 2011
since the upgrade i see all avaible wifi networks as they have 100% signal, both in NetworkManager and Wicd.in iwconfig and iwlist the signal levels change, but the link quality remains the same: 70/70 (see below). What could be worng? What can i do?
comp. model:
msi wind u100 netbook, ubuntu 10.10, kernel: 2.6.35-24-generic i686
lspci:
Code:
02:00.0 Network controller: RaLink RT2860

So I have an MSI Wind U100 which when plugged in is ok, but when I unplug it for a second it yells at me and says that my battery is critically low and needs to hibernate, then it hibernates, regardless of which button (cancel or ok) I hit. Then when I resume from hibernation still unplugged it acknowledges that it's at the appropriate battery level. I'm running Ubuntu 10.04 and I couldn't find any clues in dmesg.

I'm not sure where to post this but seeing as how, at least as far as I can tell, the problem is related to the wireless card or drivers, I figure this is as good a place as any. On to the problem, I recently install openSUSE 11.2 Gnome on my MSI Wind U100 netbook. Everything appeared to work fine right after install, wireless and everything. However, soon after that I began having issues where the screen would freeze and I would be unable to do anything until I force restarted the computer.
Now I believe the problem is related to my wireless as this problem occurs most frequently when I am either downloading a lot of data over wifi or fiddling with the network. I have had it freeze many times while switching wireless networks or while experiencing wireless issues such as an intermittent connection. I may be completely wrong in my above analysis of the problem, but I figured i need to post somewhere to get started. If anyone feels this post may get more help in another forum, please just let me know.

I LOVE Ubuntu,but the sketchiness with WIFI in Ubuntu is really frustrating (not that it's Ubuntu or GNU/Linux's fault necessarily). I'm trying to find a good WIFI card replacement for my girlfriend's MSI Wind u90, but seems both the Intel 3945abg and the Intel 4965agn - the cards usually recommended for that model - seem to be spotty at best in all recent versions of Ubuntu including the last long-term release. Has anyone had success with a Broadcom 1020 (in any laptop but especially in a netbook)?

I was running windows vista 32 bit (NOW UBUNTU 9.10) on my custom built pc with a TP-LINK TL-WN353GD wireless pci card, before on vista my wifi signal strength would be in the low 70% range with a speed of 54 Mbps from a access point roughly 250 yards away, now with ubuntu 9.10 signal strength in the 15-20% range with a speed of 1 Mbps. My question is, what is the best way to overcome this wifi signal strength and speed problem, it is a noticable performance disadvatange easily seen on a website like ..... where as before videos would play 95% of the time without having to stop and catch up, would a different wireless pci card be a better choice than what I have, or is the problem in the software as in a driver incompatability or lack of correct driver, not sure how to remedy the problem.

I just installed 10.10 on a Dell Inspiron 1300. The wired connection(eth0) works fine but I get no wireless signal when I unplug and try to connect to my network/internet. It shows that wlan0 does exist but it gets no signal. I've used the rfkill to make sure that it wasn't blocked and everything seems to be ok, except I get no wireless signal.
I uninstalled Network Manager and installed Wcid and it found nothing. I even tried installing several signal scanners I found in the package manager. I've removed, updated and reinstalled the broadcom drivers. I still get nothing. The wireless signal from my router is nonexistent according to Ubuntu.
The wireless works fine when I put my windows XP HD in and it also works fine when I put my Mepix or PCLinux OS HDs in the laptop. So I know that the wireless card is not busted.

i recently got an msi wind U100x running on linux suse enterprise 10 sp1. i am totally new to linux and i believe that msi wind is not helping. i remember at some point seeing an icon in my toolbar to indicate available wifi networks, but it disappeared a few weeks ago, and i was never able to locate it again. out of dispair i reset the computer to factory settings. all i have is "no network connection" icon, and when you click on it you have both enable networking and enable wireless.
i read somewhere in help that i should have a knetworkmanager, but i can't find it anywhere. all i see in my control center is network card, and when i go in there, i go to 'user controlled with networkmanager' and i see 'micro-star international ethernet controller not configured'. before i reset to factory settings i used to have a wireless card as well.
in a word: i am totally lost and don't know where to start. any step by step to help me connect again?

I have discovered the world of freewares not long ago and it surprised me! To go a bit further, I have installed Lubuntu 10.4 LTS on an old laptop: HP Pavilion zv5326 with 256 Mo RAM.
Everything works fine except the wifi.
iwconfig returns for wlan0:
IEEE 802.11b ESSID:"Livebox-afe5"
Mode: Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry Long Limit:7 RTS thrff Fragment thrff
Power Managementff
Ifconfig returns nothing for wlan0
From what I understand, my wifi card is recognized so I do not need to install a driver with ndiswrapper, right?
What should I do then? Is there a solution at all?
(Livebox-afe5 is the wifi connection I use with my other laptop.)

I have been using windows 7 for awhile now, and i was using connectify (an internet connection sharing program that turns your laptop into a wireless router), and i'm planning on completely switching to Linux from a dual boot, and i was wandering if there is a way to share an internet connection (mainly to my PS3) on Ubuntu 10.04 x64, and wirelessly if possible, though i wouldn't mind if it was through Ethernet.

I've got a Belkin F5D8055 v1 wifi usb adapter. I use the rt2800usb driver for it. Strangely it uses only 54 Mbit/s instead of 300 Mbit/s. I thought it was ok, since I use the wifi only for accessing the internet. However, the network manager keeps dropping the signal, and I can't understand why. I'm close enough to the router.
iwconfig:
wlan0 IEEE 802.11bgn ESSID:"MyHomeRouter"

I see the Wifi Signal Strength icon on the top bar, but where's the label that shows the signal strength percentage? Is there a way to re-enable the label or did Canonical deemed it to be unnecessary?

I have a MSI netbook, U100, on which I've installed Ubuntu 10.10. This keeps disconnecting from the network, though the applet shows me that the netbook found it. I mention that I have a wireless network and another laptop, with WIN 7, where I have no problems with the Internet connection. I also have a 3G USB modem, which let me connect without problem.

Does anyone know how to stop ubuntu (when loading) looking for wifi signal's in the 5000000 khz range? I have a problem with other devices around my house that operate on this range of frequencies and it effects ubuntu while its booting, to the extent that it won�t load. My wireless router is on the 2000000 khz range therefore I only really need Ubuntu to look for devices on this range of frequencies. If anyone know a way to prevent Ubuntu looking on the 5000000 khz range by editing something I would be very greatful to know how to do this.
As at the moment I am having to boot about 5 times until it eventually decided to load. Sometimes the only way I can get in, is by going into recovery mode, dropping to terminal and typing in: "sudo gdm" and eventually I get it. Which is a right pain. Please see my previous post outlining my problem: [URL]

I just installed 10.10 on a my new Aspire One Acer netbook and I got a mobile broadband USB stick from Wind mobile.
The stick is activated because it works on my 20 GB Windoze 7 O.S. but it doesn't work at all on my 140 GB Ubuntu O.S. Both systems are on the same machine so I know it's not a hardware problem either.
Here's what happens: I log on to Ubuntu, plug in the stick and I select the "New mobile broadband GSM connection" in the network connections menu.
From there I selected my country (Canada) and my mobile provider (Wind Mobile) than I selected my plan (Mobile Broadband) and my APN (broadband.windmobile.ca).
Then the stick blinks slowly and the network icon looks forever for a connection but no matter how long I wait no connection ever establishes. My roomate has it working on his HP laptop Ubuntu but no luck on mine. The stick just keeps blinking, a steady light indicates a connection.

I'm facing a strange problem after upgrading my Ubuntu to 10.10. After I start up the system, the wifi is not getting connected by default (which was getting connected automatically in the earlier version). So I right click on network manager and click on 'Enable Wireless' option and it gets connected. So far so good. Now I close the laptop lid - it goes to sleep mode and after it wakes up, the wifi never gets connected. When I right click on the network manager icon, the 'Enable Wireless' option is disabled! I have to reboot my machine to get connected!
Here are the details:

I would like to re-raise this topic that I have seen on other discussion boards but seems to be going no where.I have been using Ubuntu for many years now having switched from other distributions. All my machines ran some version of Ubuntu, until just recently. I upgraded my personal HP TX2500 from 9.04 to 10.04. No problems. After 10.10 had been out for a while I upgraded again. The wireless would drop when busy/(signal slightly weakened) etc. It would not function again unless the wifi module was reloaded.
Then I installed 10.10 on my HP NC6400 the same thing occured. I installed Ubuntu 10.04 instead. It seemed no better. After some Googling, it seemed I was not alone. I tried all the suggestions I could find and none of them worked. One suggestion was to install Fedora 14. This works perfectly on the nc6400. The HP TX2500 has been reinstalled back with 10.04 where the wireless seems ok and I assume I am stuck there for a while.
Now my question is why would the networking behave this way for Ubuntu 10.10 (10.04 as well on the NC6400) but wireless on Fedora 14 is perfect (I mean really good! Better than either Ubuntu 10.04 or 10.10 on any of my laptops) on the NC6400. I am hoping that we can find a way to fix this, otherwise I will likely have to drop Ubuntu completely because I do not have an upgrade path for laptops. There must be many other users in the same position who are not discussing it and just rebooting each time this occurs. This must give a negative perception of otherwise great software.

after upgrading to 11.04, I can't use the fn-f2 combination anymore to activate the wifi card. I'm using a Dell latitude laptop. Wifi is functioning normally when it's on and I can even turn it off with the hotkeys. When I try to turn it back on, the light goes on for a second and than dims again. I than have to reboot into Windows to get it back on, which is kind of annoying.

i've got an IBM thinkpad 1858. fedora 11 & 12 (KDE spin) were always running without any major problems. today, i upgraded the system from f12 to f14 using preupgrade (and a wired internet connection). the upgrade process went smoothly.
but now i don't have a wifi connection anymore - there is no icon shown in the system tray and the led does not blink. the network configuration tool shows eth1 to be inactive and the button to activate it is grey.
lspci -v shows:

I have just upgrade to natty from maverick and my usb wifi dongle doesn't want to work. The usb wifi adapter i use is a Thonsom Speedtouch 121g. When using ubuntu 10.10 it work's fine after installing the package linux-firmware-nonfree, but after upgrading to natty it has stop working (the linux-firmware-nonfree package is installed [don't know if is the same version or an upgraded one]).
The network manager doesn't display available wifi nets. The output for lsusb is:

I'm on a Dell Inspiron 6400 which had been running Ubuntu 10.10 (32 bit) perfectly.Today I upgraded it to Natty and the wifi now refuses to work. Details: While no Additional Drivers were needed on 10.10, upon installing Natty it prompted me to install "Broadcom STA proprietary wireless driver". Now when it's active I don't even have the option 'Enable Wireless' (only Enable Networking). If I disable STA the Enable Wireless option comes back, yet I can't actually search for wifi networks or connect to my saved one. The keyboard key to enable/disable wireless also does nothing.
I can take this laptop to somewhere with an ethernet connection for an afternoon if need be, but am currently stumped as to what to do. Obviously I know this machine can handle Wifi under Ubuntu - it's definitely a Natty problem.

i have a dell 1501 that has been upgraded from 10.10 to 11.04. everything was working okay. and then the user ran an upgrade recently. subsequently the wifi has mysteriously stopped working. it connects okay if one plugs it directly into the router but the wifi seems to have just stopped working.my mini 9 connects fine to the netgear wifi router using wireless.when i run the system tests for networking i get the errors..."root could not find def gateway info /proc""root could not find default gateway by running route"here is the output from some diagnostic commands.NOTE:this is similar to a post titled "wi-fi dead?" but the output is not quite the same...
