Ubuntu Networking :: Cannot Connect Wirelessly Using BCM431 WLAN Card
May 17, 2011
I upgraded Ubuntu to 11.04 I can NO longer connect wirelessly using my BCM4312 WLAN Card. It connected with no problems before dist upgrade using Ubuntu 10.04. Im really not sure why I cannot connect. I cannot even see my router in edit wireless connections settings. I can however see my neighbours routers who are using WPA2 encryption. But I cannot see my router.
I have uninstalled and reinstalled The Broadcom STA proprietry wireless driver several times using Additional drivers. This did not fix my issue.
I am connected by ethernet at the moment so I do have internet connection.
I am running Jaunty, and trying to connect my TV to my PC wirelessly. Can anyone suggest a PCI card that I can use for this job that will work out of the box ?
I have 2 computers,one is connected directly to internet with a classic rj45 cable. it has a usb wireless dongle too (ralink)the second has a usb wireless dongle but no network card.is it possible to connect the second computer to internet through the first? (second computer connect to the first computer through wireless and through it to internet)infact in first computer share internet with usb dongle.
I am having problems connecting to my Fedora machine wirelessly. What i mean is that if i try to access samba \192.168.1.93 rb while connected to my wireless network i can't connect.The only way I can connect to this machine is if i connect my laptop directly into the router then i can successfully connect.Does anyone have any idea why this is happening? The strange this is i used to could connect wirelessly.
I recently installed Ubuntu on my parents IBM Thinkpad T41. Everything is great except for the only thing they use it for and thats the wireless internet. When I click on the connection icon on the desktop it picks up a strong signal but wont connect.
I am trying to install ubuntu on an HP Pavillion dv7 laptop. The installation worked just fine. However, I cannot connect to our Linksys router wirelessly.
I'm not completely new to ubuntu, I've been using it for about 6 months, my laptop, suddenly decided to no longer let me connect wirelessly, it was mid pidgin conversation, I couldn't even tick the box to enable wireless. So I read in one of these posts that one person had to reinstall their wireless driver to get it working again. so I uninstalled my driver (Broadcom STA) however when I went to activate it, all I get is the error message installation failed and to look for log "/var/log/jockey.log" and here I admit that I'm not knowledgeable about computers since I'm not sure where to look for the log and also what the log would mean.
i have a dell inspiron 1764 windows 7. it will connect wirelessly fine on windows 7 side but when i boot to ubuntu cant detect network or anything. what do i need to do.
I have been trying to wirelessly connect to my network for weeks now. My netgear dongle is fully working. I have installed the driver using ndiswrapper. I can see my network and signal is excellent; everything is working perfectly. When I try to connect it thinks about it but never connects. The password is fine; it works great with other computers. decided to have a go with wicd, so got rid of the Gnome network manager and installed wicd. Adaptor and wicd appear to be working brilliantly EXCEPT I cannot connect. wicd tells me its a bad password. Password fine because it works brilliantly with every other device I connect to my network. If I remove security from network, it tells me it cannot get address, even though it sailed passed that with no problem when there was security. I have searched the internet for a solution to this problem time and time again. Lots of people seem to be having this problem, but no one knows the solution. Is there a solution? It happens with both Ubuntu 10.04 LTS v1 v2 and Ubuntu 11.04. What the heck is going on. This happens with WPA WEP and anything else I try to use
I just installed ubuntu 9.10 netbook remix (karmic koala) on my eeepc so im pretty new to linux but getting the hang of it. i was running windows before and the wireless and wired connections were perfectly fine. when i installed ubuntu, i chose it as my main system and wiped windows. now i cannot connect to the internet through the ethernet cable or wirelessly. even though i put in the right ip adress etc it doesnt work. the wireless doesnt even pick anything up so i uninstalled network manager. i installed wicd network manager and that doesnt pick anything either. BTW using a Ralink RT2860 network card.
specific Ubuntu supported WLAN PCI-cards? This link shows a list of supported PCI-cards, but which is best: [URL] And the installation needs to be easy! I�ve tried installing these PCI-cards in my computer, useing Linux drivers, NdisWrapper, etc. Unforutately without any success:
- DWL-G510, Ralink Chipset, Ralink RT2561/RT61
- Realtek Semiconductor, RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller
I have bought a new laptop with win7 on it , I delete win7 and install ubuntu64 everything is ok but my wireless card won't work ( it is recognized) and even I can connect to INTERNET but nothing is download or upload so I have bought another usb wireless card but now when I connect this new card to my laptop it still tries to use the old one and so I could not connect to internet
I'm a new user of Ubuntu and I think I need some help but let me mention before that I got this up working on a Debian system.My current kernel version is $ uname -r 2.6.32-27-generic.The problem is that my wlan card is not working any more such that my system freezes every time I enable networking with the hardware switch on my laptop.Therefore I bought a USB - WLAN stick and try to get this working.
Network Manager has the option "enable wireless" greyed out if I disable the hardware switch.If I enable the hardware switch and remove the module of my wlan CARD before (modprobe -r iwl3945) it says "wireless disconnected" for all networks.
Am having intermittent connectivity issues with my stock Atheros AR5212 on my Thinkpad X61 using Ubuntu 10.04. Am wondering if there is a known to be good b/g min-PCIe card that I can replace my AR5212 with that would be more solid in Ubuntu?
I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.
I am trying to connect to a WEP encrypted WLAN without using the DHCP server of the AP. (=giving myself a static IP)
So far i have tried:
Code:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?
I have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
I'm having trouble setting up new Alix URL... system with a wireless card. I got the card from an old working Buffalo AirStation router. The card is a WLI-MPCI-G54 and is using Broadcom BCM4306 chip. I've installed Debian on the system.My goal is to make a wireless access point by using hostapd authentication service. I thought it might be a good idea to verify that the wlan-card is working properly first, but it can't seem to detect my local wlan.
I have a problem on Ubuntu 11.04 64-bit. The wlan does not connect automatically on reboot, although "Connect automatically" is ticked in network manager. I always have to choose "Connect to hidden wlan", choose my config, enter my password, then connect. Once connected everything works fine. But it's kind of annoying to manually connect each time after a restart.
- hidden SSID from router - mode -> infrastructure - connect automatically -> ticked - available to all users -> ticked - Encryption -> WPA & WPA2 personal
I have a Dell WLAN 1397 Half Minicard, 802.11 b/g card in my laptop, and I can't seem to get ubuntu to work with it. I tried this method:
1. Synaptic Pack Manager 2. Check "Install from Boot Disc" 3. Reload 4. Install and apply bcmwl-kernel-source 5. Reboot
This didn't work for me, so I tried entering sudo apt-get install bcmwl-kernel-source and that also didn't work. Another thing I tried is formatting my Ubuntu partition and reinstalling, and retrying both of those methods. The ethernet port does work, however.
I'm using Ubuntu 9.10 on a Lenovo ThinkPad T61 using an Intel PRO/Wireless 3945ABG. My laptop's ability to connect to a wireless network stopped last night, and I'm not sure why. It's definitely something on my end, as my roommate can connect to the internet on a Windows box. I can wire in without a problem, but that's a pain and my Ethernet cable got lost in the shuffle when I moved back to school. I've been able to get into this network before and nothing about it has changed. I've been able to hibernate and restart and such and nothing has ever needed to be reset.
The router's a D-Link WBR-2310. Wicd and Network Manager see the network (I'm back to using wicd) , but wicd appears to get stuck at "Obtaining IP address..." and says "Unable to connect: Cannot obtain IP address". I know my password is correct (I set up the router and I'm the CS undergrad in the apartment so I manage it), lspci sees the wireless card, ifconfig and iwconfig return information about the interface, dmesg|grep wlan0 doesn't seem to have anything terribly out of the ordinary, but here's that output:
Code: allyanncah@taliesin:~% dmesg | grep wlan0 [ 23.514202] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 36.609016] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 38.756143] wlan0: direct probe to AP 00:24:01:cb:4e:7e (try 1) [ 38.758791] wlan0: direct probe responded [ 38.758796] wlan0: authenticate with AP 00:24:01:cb:4e:7e (try 1) [ 38.760587] wlan0: authenticated [ 38.760609] wlan0: associate with AP 00:24:01:cb:4e:7e (try 1) [ 38.763318] wlan0: RX AssocResp from 00:24:01:cb:4e:7e (capab=0x431 status=0 aid=1) [ 38.763322] wlan0: associated [ 38.765502] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready .....
I've tried: - reinstalling wicd - uninstalling wicd and installing network-manager - restarting - shutting down and booting back up - restarting the router - sudo /etc/init.d/networking restart - taking the interface down and back up with ifconfig
I haven't changed anything recently in regards to my wireless card, and all the fixes I've tried are things I've done before without an issue. The only thing I'm wondering about is if doing a hard reset might have broken something (I know this is a cardinal sin, but there's a whole 'nother problem I haven't been able to fix with the OS hanging every once in a while over a VPN daemon when it tries to shut down or restart -- I've left it for hours to see if it actually gets anywhere and no luck, won't do a soft reset). I'm nervous about reinstalling the driver just because I've never had to do it and drivers are a finicky business. I imagine there's a config error somewhere?
I am trying to connect an Ubuntu 10.04 desktop system wirelessly to another desktop that is directly connected to a cable modem via dlink wireless router and ethernet card. I have not been able to connect on the second system (Ubuntu) to the wireless router.
I have a RedHat linux server box connected to LinkSys router through ethernet port. I've assigned a static IP to the Linux box, which is out of range with router's DHCP range.
The Linux box has Apache, JBOSS, SVN and several other services installed, but none of these services are accessible through the WLAN. However, SSH and SFTP are accessible from WLAN.
Another interesting observation is that if I open a browser on the linux box (by exporting the DISPLAY to Exceed on my laptop on the WLAN) and point the browser's address bar to localhost:80 or localhost:9080, then I can access these services!!.. So, I suspect that something is wrong with accessing these services from a client on WLAN and I am looking for a solution for the same.
recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.

Since I have installed Fedora 13 it seems that I can't connect to WLAN APs which aren't secured by WPA. I'm surprised about the inserts to the messages logfile:
[Code]...
Most surprising insert for me: Jul 5 20:43:21 nbtobiaslnx NetworkManager[1328]: <info> Config: added 'key_mgmt' value 'WPA-PSK' Is this the reason for my problem? I use KDE and Network Manager for managing my networkconnections.
I've just got a TP-Link wn-851n PCI WLAN card, and the problem is that ubuntu can search for the network, but I can't join into the network after typing the password. I'm sure that it is correct as m Windows notebook is also using that network.
Taking a look in dmesg, and it start to loop this message after I joined the network.
I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
i am having trouble getting my wireless internet to work on ubuntu 9.10. i just installed today and it works perfectly fine when connected with the cable. i right click the network connection on top and the "enable wireless networking" is not there. only the "enable networking". i have a dell laptop and there is a switch in the front that enables the wireless adapter when i use windows. but on putting the switch into the on position it doesnt turn on, it stays off. i was hoping that someone would be able to help me, i dont want to have use an ethernet cable everytime i use my laptop.
