OpenSUSE Wireless :: Suddenly Cannot Access Network
May 25, 2011
Today I changed my home router's security setting from WPA to WPA2, and my openSUSE 11.4 Tumbleweed system's network stopped working.It is very strange, because it can connect to the wireless no problem and it gets ip address and everything, but I cannot access any websites. I tried to revert the router setting back to WPA, but still the same.Funny thing is I can actually open the router admin page.
Even I plugged the wired lan cable to my laptop, but still the same. It connects, but no internet.Where should I look? My the other laptop with openSUSE 11.4 connects to the same router without any problem.

I am running SLED 11 and My Networkcard is Intel PRO/Wireless 5300. In short, it is not there anymore! I mean I was connected and everything and the next time I restarted It could not detect any wireless network. I deleted the wireless network card in hopes that the OS will automatically detect it on startup and set it right but NOPE. When I check the hardware information in YAST, it is listed there and it is also working under Windows.

System Information:openSUSE v11.2 32-bitdesktop: KDE 4.x (.3 I think)Background info: Installed openSUSE 11.2 on an old HP laptop this morning. I've been trying to set up my wireless connection since. After 2-ish hours of searchingupport forums, I managed to use network manager to connect to my home wireless network via WEP, I will say now that I've had lots of trouble.
I've finally been able to connect to my network, to a point. The NetworkManager in openSUSE says that the wireless connection is active. I can verify this by saying that on the other conputers in my house (winXP, win7, and Ubuntu v9) I have been able to ping this openSUSE computer and my router recognizes it as part of the network. Here is where the problem arises: I cannot access the internet from the openSUSE machine, with a domain name or by trying to type in an ip address, and I cannot ping other computers on my network with it.

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 just installed Opensuse 11.2 dual-booting with Windows 7 on a laptop. I have the wireless set up and connected, but I can't seem to be able to connect to any websites or ping Google, etc.I'm kind of a Linux newbie, so I'd like to get some advise as to what I can check to get it working? (Windows 7 on the same machine is able to connect - I'm using it now)
- I've tried both automatic DHCP configuration and also setting the ip/dns server manually, no luck

I have Lenovo G550 and openSUSE 11.4. Everything's ok, wifi without problems, I could connect to anywhere I wanted to, but yesterday while laptop was running and was connected actually by wire to internet, after removing the wire I realized that I cannot connect to wifi (the laptop was hibernated during night) - even the light diode in the front of the laptop was not shining. I went to yast and realized that the wlan0 isn't enabled and there's new eth1 port. But the wlan by ifup I cannot start and the eth1 I cannot start as well.

I'm trying to setup a wireless AP with my old asus eeepc, so it can act as a repeater to connect my android device on the other end of the apartment. I've already created the Wireless Access Point using hostapd. It took very little configuring, just changed from mode 'a' to 'g' and changed the channel from 60 to 1 and It was all set. Next I setup a dhcp server. Also simple enough using yast.
Up to this point, I was able to connect my android device to the newly created wireless network. However It doesn't have internet access. I guess I have to configure iptables for this, but I find it incredibly confusing! Here are a few specs to help with any examples: The laptop is connected to the internet through eth0 with IP 192.168.2.120 Hostapd is using wlan0, and I'm pretty sure it created mon.wlan0 So, to sum up, when I connect my android device to the network I can, for instance, see what ever pages apache is currently serving on the laptop, but can't access the internet.

I'm unable to get into my university's WLAN network. LAN works just fine, but sometimes it's quite convenient to be able to access stuff wirelessly. It doesn't seem to be a hardware problem, because if I configure my computer according to our computer department's instructions it works fine with Ubuntu (currently I carry around a stick to get into the Internet when I really need it and don't have a cable). Some info:
My device:
Broadcom WLAN controller on a Lenovo G560
My system:
OpenSUSE 11.3 64-bit
The drivers are installed, I can get into normal private networks, but have never managed to get into the university network except for with Ubuntu.
The university instructions tell me to use the following settings:
Security: WPA Enterprise
Authentification: TTLS
Inner Authentification: PAP
Username: My username
Password: Password
CA Certificate: Deutsche_Telekom_Root_CA_2.pem
In the KDE instructions, they tell you to write "anonymous" into the anonymous identity field, but in the GNOME instructions it says to leave it blank. In Ubuntu, I leave it blank and it works.
I've got the recommended settings, which also work in GNOME.
I'd ask the tech support here, but I am the tech support We've got it working with other systems, like I said, but not with SUSE, and I'm a SUSE fan.

I have installed Suse 11.4 from the Gnome liveCD, and I "can" access my home network when it is unsecured, however, I can't access it when WEP is turned on. Now, I know that WEP is insecure but there are devices on the network that only supports WEP so the router settings can't be changed. Also just for testing purposes i have tried the WPA2 encryption method to no avail (dmesg reports that the connection timed out). The only encryption method that looks promising is the open-wep encryption. When trying to connect to the network (with open-wep turned on) I have performed a bit of checking to see what is going on, now I don't know much about in-depth linux and stuff but, below are the outputs from lsusb, dmesg, iwconfig, and ifconfig.

Code:
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

using opensuse 11.4 on laptop--we went down the shore and I added a bunch of wireless connections and it was working down there, but now we came back and I deleted all of them except my wireless network connection. I'm not sure if anything else was messed with as others were using this laptop.
When I start up the networking icon says Unavailable.....when I click on it greyed out is "Network Management disabled" and "Enable wireless" The Wireless light on the laptop is a solid orange. When it is working it is flashing.
What do I do to troubleshoot this? I am fairly noobish to linux.

Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.

I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error
- no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

My wireless is a libertas 88w8335. Suse 11.4 just installed. For this one, I need a windows driver with ndiswrapper. ndiswrapper is installed, and the driver as well.
I can see my networks with iwlist scan my network is set up in yast with ifup (I can scan the networks and find mine), but I cannot connect to my Acces point : there is no SSID with iwconfig.

I got a development machine with Apache installed. Everything was configured correctly, machine was running perfectly for some time, but today, suddenly I lost connection to my Wireless network.
Now I simply...can't access it. All details are correct, I even turned off MAC Addresses validation to make sure it's not my AP configuration fault. Nothing helped.
Any ideas what could happen? I did not update any libraries/packages. Just got disconnected from my network and cannot access it anymore.
To give more informations: I'm using Broadcom wireless device and b43 driver but I don't think this can be an error. Logs tell me nothing.

What program should I use to access my wireless network in KDE Trinity? I'm used to using KNetworkmanager (KDE frontend for network-manager), but apparently, KNetworkmanager doesn't work in Trinity. What's the next best thing?

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.

I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager

i have 3 comps(running suse 11.3) and a laptop(running vista sp2). i have installed samba on all suse comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet. the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.

So I finally successfully installed Ubuntu 10.10, but I can't access my home wireless network. I dual booted with Windows 7, and it detects my local wireless network, asks for the key and connects correctly. In Ubuntu, I have to plug in an ethernet cable to access the internet (like I am now). Ubuntu doesn't detect the network, and I tried "Create New Wireless Network..." up the top right, but it doesn't connect.

I have a fairly new install of 10.04 on a Dell laptop (about a week). Everything was running well, connecting wirelessly to the interneet through my home router (WPA/WPA2). Today, for some reason, I lost my connection to the internet. The network manager tells me I'm connected to my router, but all the lines on the wifi indicator are gray and there is no internet access. I reinstalled the 2 sets of packets for my BCN4312 (bcmwl-kernel-source and b43-fwcutter ), but no change.

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.

New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.
Firewall
Disabling the firewall makes no difference.
Not using a network manager (can't see how to assign fixed address if I do - all greyed out).
ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'
(not sure why the warning - eth0 is assigned to external in the firewall setup).
