Ubuntu Networking :: Wireless Network No Longer Working On Mobile / What To Do?
Aug 19, 2010
It still works fine if I boot into "good old" Windows. I must say I am SOOO disapointed with the Network Manager in Ubuntu which was great until 10.4 and has been crap ever since. I have had so many problems with my Vodafone USB and had to find an alternative method of getting it to work. Now the last straw is that my wireless LAN card is not getting recognised on startup so I have not connectivity when at home. (USb via Vodafone is no good in my area). I am typing this via an old Windows PC because my Ubuntu just does not work anymore. I have not installed anything new so what has happened - or how can I get it to work again.
I was completely sold on Ubuntu but am now considering reverting to Windows. It would be worth paying for an operating system that actually works, even if I have all the other hassles as well. A year ago Ubuntu was great - it all worked ! Not any more how can all that good work have gone down the pan - I can't understand how anyone could let all these nertwork problems occur - it isn't just me - read the threads - it's widespread.
The problem with my wireless network. I have Dell DV6 Pavilion 2115 eg laptop and i installed Ubuntu 11.4 and internet and wireless worked, until i reboted my system it has disapear. I cant no longer to connect to a wireless network. It dont shows me any wireless network. My wireless card is Atheros AR 9285 802.11b/g/n Wifi Adapter
A couple days after an update to Ubuntu 10.10's networking stuff I was unable to connect to my wireless network that had a password. Now, I can connect to a different connection that doesn't have a password but when I try to go to mine it doesn't work.
Running on a compaq nc6000
And yes I do know that the password is correct as I am connecting right now on Win7.
I have a Acer Aspire running dual boot Ubuntu 9.10 and Vista. Although it has an Atheros wireless card (AR5001 according to linux, AR5007 according to Vista) until recently I didn't have any apparent problems with it.I installed a ZTE MF112 Mobile Broadband Dongle. Now I am experiencing great difficulty in communicating with my wireless router (with both LAN and WAN traffic). Connecting to the network in the first place appears to happen quite smoothly and my computer obtains a DHCP IP address. However the ping response times are measurable in seconds rather than the milliseconds I would expect, and any traffic across the network crawls, or just times out and fails.
I do not believe it is the router at fault as two laptops, both also with Ubuntu, can connect to it fine and swapping it out for another router does not fix the problem either. Also there is no problem connecting from Vista.I suspect that installing the dongle has altered something which has made the bugs in the wireless card/drivers apparent and that's where I need some help.
I have internet access using mobile broadband and i also have a wireless network for home usage without internet access.
When my wireless network is connected every application in ubuntu (Meerkat) tries to use it for inernet access (as neededobviously). As soon as i disconnect from the wireless network (and assuming the mobile broadband is on) everything has access to the internet again using the mobile brodband.
How do i tell ubuntu that i don't want it to use my wireless network for internet access?
I have Dell DV6 Pavilion 2115 eg laptop and i installed Ubuntu 11.4 and internet and wireless worked, until i reboted my system it has disapear. I cant no longer to connect to a wireless network. It dont shows me any wireless network.My wireless card is Atheros AR 9285 802.11b/g/n Wifi Adapter.
recently installed 10.04 on his hp pavilion laptop and we got everything working fine, including the wireless internet. When he installed some recommended software updates his card is no longer being detected although wired networking is still fine.
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I am experiencing a bunch of problems on my Ubuntu 10.10. I will start off saying that I am a new user to the Ubuntu and Linux. I've been a user for 5 days. Anyways, I started off with Ubuntu 10.4. When using that, I could instantly connect to my wireless router and my school's wireless network. But after I upgraded to 10.10, I could no longer connect to a wireless network. Second problem is my webcam. The video works, but it won't recognise my microphone.
I just finished upgrading from 9.10 to 10.04 via the Update Manager. My first noticeable problem is that my wireless connection with my home network no longer functions on my IBM Thinkpad T42 laptop.The Network Manager applet shows that it detects my home network (and those of several of my neighbors), but I have not been able to get it to connect to this network. I've been using WPA & WPA2 Personal settings for security, and the Network Manager applet had correctly picked up the password that I had been using under 9.10. I've searched the Ubuntu Forums for "wireless T42" and thought I'd found a solution in a posting that recommended using the "wcid" network manager, but I've been unable to find wcid either via the Synaptic Package Manager or the Ubuntu Software Center.
1. I've noticed that in Lucid Lynx the Network Manager applet's icon in the top panel is no longer the vertical bars symbol that it displayed in Karmic Koala; instead, the icon is a radiating fan display. In the Network Manager's edit Network Connections window, this fan icon is shown on the Wireless Connection tab, while the vertical bars icon is shown on the Mobile Broadband tab.
2. The Wireless Connection tab shows, on the line in which it shows awareness of my home wireless network (as "Auto 389690") that this connection was "Last Used" "1 month ago". It should be saying something like "today".
FWIW, the Network Manager detected my wired "eth0" connection with no difficulty.Both Jaunty and Karmic picked up my home wireless connection without any problems. Now I have no idea what to try next.
i have lucid installed on my toshiba laptop after after an update my wireless stopped working keep asking for password and my wireless card is not detecting no wifi :
I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...
I'm new to Ubuntu - I've decided to give Ubuntu Studio a go as an alternative to Windows. However, after installing it, neither of my network cards work. I have a Intel Pro Wireless 3945ABG wireless card, and a Broadcom Netlink Gigabit Wired card. Neither work, And I'm not sure how to. I've tried searching, and have come up with the .tgz file here, but I have no idea what to do with it I'm concentrating on the wireless card for the moment, seeing as that will be the main one I use.
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 fiancé¥ 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:
I have a Toshiba MX35 laptop it's a little old but does the job. I'm have a problem getting the wireless to work. I can boot a live CD either Ubuntu 10.10 or Fedora 14 and they will see the wireless card. The card is Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01).
I have Ubuntu 9.10 installed and that is the OS that is having the problem seeing the wireless. The computer will not handle Ubuntu 10.10 (at least it won't handle the desktop effects under Ubuntu 10.10) but handles them just fine under 9.10 and that's why I have 9.10 installed. I really need the Wifi to work because I'm going to travel in a few days.
I don't know what I did but I can't connect to the network any longer. KNetworkManager finds it but I can't connect. It stops at waiting for authorization. I've been connected before and it still works in xubuntu but something happened here. Here is what /var/log/messages/ says
Code:

I have a Belkin F5D6050 adapter, which (despite being only 11b) was working better than my 11n adapter on 11.1 [The 11n stopped working today after I ran an upgrade; I have got it working - in a fashion under 11.3 - see RTL819SU not working with ifup (needs ifup-dhcp first)] I can't connect to my AP. The significant output from dmesg appears to be:

I am also using gnome-NetworkManager. If I left-click on the NetworkManager icon down on the taskbar near the clock it shows "Wired Networks" with eth0 connected, and "Wireless Networks" is blank under the heading, last week I believe it said something like "device unavailable" or something like that.
Network Details: iwconfig Code: lo no wireless extensions. eth0 no wireless extensions. [Code]....
I was curious about when the last time I was able to successfully use my wifi so I checked to see in NetworkManger and it just so happend to be that I was on a business trip in Atlanta on a different network then am usually connected to. Don't know if that has to do with anything but I thought it was worth mentioning.
Also, I thought it may have something to do with assigning an IP address static-or-auto but I am not too familiar with NetworkManager to check that.
I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network. Tried a few bits of poking it blindly with a stick:
matthew@ubuntu:~$ lshw -C network Warning: you should run this program as super-user. *-network Description: Network controller Product: BCM4312 802.11b/g LP-PHY Vendor: Broadcom Corporation Physical id: 0 Bus info: pci@0000:0c:00.0 Version: 01 Width: 64 bits Clock: 33MHz Capabilities: bus_master cap_list Configuration: driver=b43-pci-bridge latency=0 Resources: irq:17 memory:f69fc000-f69fffff *-network .....
I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either.
I have had this configuration at home for years, but I just changed my line provider and I cannot get it to work.
I have a desktop machine with two ethernet interfaces, eth0 and eth1. Etho is connected to the cable modem and that seems to be working fine - well, I'm posting here, right? Eth1 is connected to a Linksys WAP54G wireless access point. I have eth1 set to 192.168.1.240 and the AP set to 192.168.1.245 (the default). The desktop runs CentOS and I have dhcpd running, and I have focused on the dhcpd.conf file, which I have changed many times. Here is the latest incarnation:
Code: # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.sample #
I'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.
I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.
Since an upgrade from 10.10 to 11.04, all wireless devices for me in the plasma network manager applet are not functioning properly on a Dell Latitude E4310. Specific problem: No wireless networks appear in the plasma network manager applet. Manually-configured networks do not connect. A separate CDMA card appears, but cannot establish a connection. The CDMA card does function on 10.10 machines, and formerly worked on this machine. The only wireless 'network' that appears in the plasma network manager widget is 'hidden network'. Manually adding a network and checking "Connect Automatically" does nothing. I attempted a fresh install after the upgrade itself failed the work. There are no networks to click on, and selecting the device itself merely shows the status page.

Neither the CDMA card nor any wireless networks are working. If I take the exact same machine and boot from a disk with 10.10, both work.
I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.
My mom just switched from Comcast to Clear 4G Mobile Internet service and I don't know how to get this working on a Ubuntu 10.04 system. The Clear installation USB only gives me two options: Windows Users and Mac OS X Users. I was wondering if the Linux WiMax driver would be instrumental in having Clear work on my Ubuntu 10.04 system. From this website: [URL]..
However, if there are no other options, we do have 10 days to back out of the contract.I'm a dim light bulb when it comes to these things. If I didn't provide enough info, just let me know!
I upgraded from lenny to squeeze on a notebook and I can no longer connect to the wireless network. The computer is an LG notebook and the network card is ralink rt2860. I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked
Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.
Here in India I've been given a USB dongle for my Airtel SIM that isn't recognised by Ubuntu. The dongle is an Icon031 EDGE, model: GI0031, serial number begins ME.usb-devices shows that the driver appears to be installed:Quote:
I have a strange problem with my mobile broadband connection. I hope I am not the only one (so it will be fixed), but since I haven't found any others having the same problem yet, I am not so confident.I started using mobile broadband, via a HUAWEI E1762 HSPA USB stick since Jaunty. I've had the same problem in jaunty as I do now in Karmic. Although in Karmic, i've had additional problems (that problem i've found listed as a known bug).The problem is that when I get my mobile broadband to connect, it is sometimes, somehow, not fully connected. Symptoms are as follows:
1. panel icon shows connected and good strength (good) 2. skype connects, and I can chat and voip (good) 3. ping does not work (bad)
My friend switch to Ubuntu (he has a 9.10) and want to set up the mobile broadband. He has a usb modem stick Hyundai mb-810. We tried everything - from the usb-modeswitch to wvdial and nothing works. We have read millions of pages of tutorials and forums but still - nothing works. He is now thinking to go to Windoze XP and leaving the Linux community though he is impressed with the Ubuntu.
Ubuntu 9.10 working great. Installed Orange 515m as per fix shared on this and other forums; however while it works great at home, it will only 'connect' once at work - on subsequent attempts it connects, but browser etc behave as though they cannot find the modem and I cannot make further connections via gmail and Firefox. I had just made the swap from Win 7 to Ubuntu 9.10 for work as well as home, but I cannot be in the position of being unable to access my emails and so swapped my hard drive back to Win 7 drive today
