Ubuntu Networking :: Laptop's Wireless Card Can See Access Points But Can't Connect
Jan 15, 2011
I'm not exactly sure if this should be here and not in the Hardware & Laptops section, but seeing as my only problem is with WiFi, I'm guessing this is the right place. Under Ubuntu, my laptop (an Asus K42Ja, more details below) can see wireless networks normally. However, when I attempt to connect, it fails to establish a connection. Under Windows on the same laptop (dual boot), no problems are experienced.
According to this, there's a firmware bug in my wireless chip which causes connections to get dropped. I'm not getting connections at all, but I still tried the workarounds on that page with no luck. The router is a TP-Link TL-WR340G. My previous laptop, a really old one from 2003 running Ubuntu 9.10 was able to connect to that router without problems. The wireless card was Intel on that as well (but, of course, much older). The router is set up to use WPA for security. I didn't use WPA2 as I read something a while ago about problems with WPA2 and some Linux distros. Please correct me if I'm wrong here.
If anyone's curious, I'm posting this on Ubuntu, via an ethernet cable to the router mentioned earlier. Some tasty technical bits: dmesg (the latter half of the "timed out" messages is me retrying after double-checking the WPA key)
I have wireless G and N access points in my house. The N network is set to allow only N connections. I have a Lenovo laptop with a Intel Wireless N chip in it, and after one of the 10.10 updates it stopped connecting to my N access point. The G access point works just fine.
The logs for the Wireless N access point alway show "Bas Password." I am having the same problem with either NetworkManager or wicd.
Installed 10.10 maverick on my compaq mini 110, activated the restricted STA driver... But under the networking drop down it shows wireless as enabled but I cannot actually see any networks, there should be about a half a dozen to see. Works fine under windows. Before the restricted drivers are activated ifconfig shows eth0 and after eth0 and eth1 but when I do iwscan eth0 or eth1 it tells me this action is not supported! I have tried reinstalling from cli but no difference?
I am having trouble connecting to 1 particular wireless hotspot. It used to work in Ubuntu 10.10, but after upgrading to Ubuntu 11.04 it sees the Access Point, tries to connect but never succeeds. I can however still connect to my home router. Both use WPA2, both have a good signal. I have an ASUS UL30a laptop with a (output from lspci): Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) NIC I was thinking of installing the linux-modules-backport-net package?
Is there away to view wireless access points without being connected. I am having trouble getting connected to my wireless DSL modem. I have no problems connecting with Windows Vista. Just can not get Ubuntu 9.10 to connect. iwconfig says no associated with access point. I can connect with ethernet cable.
I used to use Ubuntu 10.04. Never had this problem. I went back to Windows 7 and then came back to Ubuntu, and 10.04.1 was released. After some usage of wireless internet, it disconnects from the access point, and phy0 has 100% usage. [URL].. I'm not the only one with the problem. I downgraded to 9.10, and haven't had that problem since the downgrade.
I can connect to my school's wireless network using the standard network manager, but often (not always) it repeatedly disconnects and reconnects every few minutes. Occasionally it also prompts me for the security information again (even after it previously connected successfully).
By running iwconfig when it's on the fritz, I can see that it's often switching access points for the network - which is what I think is causing the problem. It disconnects and reconnects even when the signal strength for the current AP is fine, and it will often switch to an AP with a weaker signal strength.
I am using a dell laptop which has Dell 1397 802.11B/G Wireless Mini Card. I not able to connect to internet and was not able to detect what actual problem is weather card is not supported (i.e. drivers are not available) .
Also, if any one can point to exact process to connect to wireless Lan using fedora12.
My wireless (Toshiba laptop, 10.04 64 bit) is just hanging when trying to connect. It was working fine but now nothing. My Wireless antennae is on and my other laptop can connect with no problems. I have restarted the router and the laptop twice.
I have two wireless access points in my home network. A Linksys upstairs and a Watchguard Firebox downstairs. The Firebox acts as the gateway for my network to the internet (well, the ISP's router anyway). I invariably use my Hardy Heron installed HP laptop downstairs, less than 10ft from the Firebox. The signal bar for the Firebox shows three bars, the linksys just one. So, why the heck does my Ubuntu insist on connecting to the Linksys everytime?! I can manually switch it afterward but still, it's annoying.
I'm totally sick of my WiFi Card, a Realtek 8187 connected by miniPCIe, althought internally designed as USB, I've tried all there is, and I've decided to change it. Which brand do you guys recommend? In my experience, I want to avoid Realtek and Atheros, but which brand offer the best "out-of-the-box" experience, and less overall issues? Intel, Broadcomm, maybe another Atheros or Realtek model, or whatever you guys think it's the best choice
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.
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
I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.
Is there a CLI command or program that will list available wireless access points? I'm running Ubuntu 9.04 on a laptop and sometimes I boot straight into the CLI instead of a GUI. I know iwconfig can configure a connection but will not list available AP's.
That is what I do to connect to Xbox Live and I just got an Insignia Blu-ray player that can only connect to BD-Live through an Ethernet connection, so I was wondering if I could apply that same concept to my Blu-ray player.
I am completely new to linux in any flavour. I installed ubuntu 10.4.1 64-bit on my Gateway NV59 laptop as a dual boot with Windows 7. The installation went just fine. When it comes to networking, I can connect to my home network when wired directly, wireless is another matter. I can connect wireless in windows just fine, so the card is physically fine.
My set up is as follows: Gateway NV59 laptop with Atheros AR928X PCI-E wireless adapter Linksys WRT54G router using WPA2 Personal and a class C address scheme (192.168.x.x) (If anyone thinks it would be necessary to post actual hardware specs of the laptop, I can, but don't think it really necessary). I have followed the Wifi Wireless Troubleshooting Guide found at [URL].
When connecting to my network wirelessly, I click the icon in the top right, and choose "Create New Wireless Network". When I input my settings (SSID - not broadcast, and security type and key - WPA), it then states I am connected under the "Wireless Networks" section found in that menu, and shows my network name with a strong signal and a computer/monitor icon. When I double-click the icon, it tells me I am connected and that the connection is active, yet the actual wireless icon on the top bar is grey, not white, and has a red exclamation mark on it. According to the steps in the troubleshooting guide, my wireless card is recognized and installed, with a driver of ath9k.
When I run lsmod, the driver is listed, therefore loaded, and ndiswrapper is NOT listed. I have verified that the driver is communicating with the kernel. When I scan for my router, it is listed under Cell 04, with the correct SSID and hardware address. There do not appear to be multiple drivers loaded, and my wifi is NOT disabled. When I check to see if I'm associated with a router, iwconfig shows my network ssid under wlan0, with the correct hardware address listed under Cell:, yet I cannot ping my router's internal ip address. At this point, I ran ifconfig, and for some reason, my wireless card has been given a class A address of 10.42.43.1.
When I try to assign an ip address via dhcp, DHCPDISCOVER runs for a number of intervals and then tells me "No DHCPOFFERS received", yet my router is using dhcp to assign ips with a pool of 50, more than enough ips for all the hardware in my network. When I run the command "sudo invoke-rc.d networking restart", I get the statement "Ignoring unknown interface wlan0=wlan0" - not sure what that means, but doesn't sound good to me, and retrying to accquire an ip address through dhcp still does not work. If I attempt to assign an ip address within my network range manually, I first run the command "sudo ifconfig wlan0 down", then just out of curiosity to see if the interface is really down.
I run ifconfig again, and wlan0 is no longer listed, but now there is eth0 (my regular ethernet interface) with no ip address. AND another interface is listed - eth0:avahi with the same hardware address as eth0, and an address of 169.254.4.42 - this seems to be the default address the OS will assign when it cannot get one via dhcp, but I have no idea why it has shown up as eth0::avahi... Anyway, after entering the command "sudo ifconfig ip addr 192.168.x.x netmask 255.255.255.0 broadcast 192.168.x.255 up" with the appropriate addresses, I receive the error "addr: Unknown host".
What I have NOT tried, are the following steps: 1. Change my router to an open signal (I would prefer not to do this, but will, if it is absolutely necessary for troubleshooting) 2. Try gtk wifi, or wifi radar 3. Try booting with kernel option pci=noacpi or acpi=off (not entirely sure how to do this just yet) 4. Try wpa supplicant (not sure what this is, just noted it was in the troubleshooting guide)
I recently switched from windows xp to ubuntu and have been very impressed so far. However, I've run into a bit of a problem. My laptop has a switch on the side that enables or disables the wireless card and every now and again its inevitable that someone accidentally switches it off. When I had windows xp all you had to do to re-enable it was to go to the device manager and turn it back on however ubuntu apparently doesn't have a device manager. so I need help. my wireless card info is05:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
I have a windows 7 (64bit sadly) desktop computer with no wireless capability. Now before I go out and spend money on a wireless usb thing, I was wondering if I could use my laptop (Ibm think pad T60 running ubuntu 10.10 dual boot with crunch bang) As a wireless access-point and connect via Ethernet cable the laptop to the desktop (Probably through a modem?) so I can use the Internet for games on the desktop computer. (Games that wont work in wine, sigh). Just a note though, 64 bit windows 7 will NOT run anything.
I have ASUS Laptop A6Rseries was running XP untill I installed Linux 9.10. Now i am having problem connecting to my wireless network. I am using Belkin router what works fine with XP, Vista and Windovs 7. Here is some information what I found
lspci 00:00.0 Host bridge: ATI Technologies Inc Device 5a31 (rev 01) 00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller (rev 80)
I'm trying to install Ubuntu 10.04 on my Toshiba A200-12U laptop (with an Atheros AR5007EG wireless card), but networking is being problematic.I entered Network Configurations and tried to get 'Auto eth0' working -- I went to Edit > IPv4 settings and filled in 'Addresses' with the details of my connection:
Address: 192.168.1.254 (the local IP of my router) Netmask: 255.255.252.0 Gateway: 184.108.40.206
I'm trying to make my F10 Laptop a wireless Access point.
When I 'iwconfig wlan1 mode Master' I get: SET failed on wlan1; Invalide argument.
wlan1 is a Netgear WG111v2 which worked as soon as I plugged it in after I installed F10. I don't know is it not supported? What is? Is there a different driver I can put on that will work in master mode.
After searching/googling for information related to the topic, I haven't been able to get this working in KDE. Background: I have a Dell Studio 1745 with builtin Intel 5100bg wireless card. It connects to my Linksys WRT54G router just fine in openSUSE 11.2 & 11.3 using either KDE or Gnome. In Fedora 13 it only connects under Gnome, not KDE. Those are using NetworkManager. Using traditional ifup only works in Fedora under Gnome, i.e. nothing works under KDE in Fedora.
