OpenSUSE Network :: Create Network Bridge / Device Hooked Up Via Ethernet Had No Internet Connectivity?

Feb 25, 2011

I'm on opensuse 11.4 (11.3 won't work with my monitor).

My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.

I also tried this command:
echo 1 > /proc/sys/net/ipv4/ip_forward

but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?

OpenSUSE Network :: 11.3 - No Network Connectivity - Audio To Work On Skype

Oct 16, 2010

I had Kubuntu 64-bit installed and decided to try OpenSUSE instead as I was having problems getting the audio to work on Skype. After installing OpenSUSE 11.3 (64-bit), I do not have network connectivity (Ethernet or Wireless)? Neither adapter can be detected? I thought the install would be fairly straightforward as Kubuntu 64-bit detected all the hardware.

Fedora :: Network Connectivity Drops Out Randomly?

Jan 21, 2010

Installed Fedora 12 recently.

For some reason, my network connectivity drops out randomly. This has happened between 5 minutes to 1 hour of booting and logging into the machine.

When the internet does work, its great, and super fast !

When it drops out, Internet stops working, cannot ping to external site and I cannot ping my router 10.1.1.1

I have onboard realtek network ports on my motherboard.

OpenSUSE Network :: Xen NAT Setup In 11.2 - No Basic Connectivity?

Feb 21, 2010

I am experimenting with Xen with the standard kernel (kernel-xen package) and utilities. I already got bridged setup to work with a single domU, but found out that because of my wireless card I cannot expect bridging to work when connected wirelessly. Now I am trying a NAT setup but I cannot seem to get any network connection from the domU to the dom0 and viceversa. Comparing the network devices and routing tables of others, I cannot see any problem.

The domU runs with IP 10.0.0.1 and the dom0 has a vif with IP 10.0.0.128 with a default gateway of 10.0.0.254. Pinging from the domU to the dom0 and viceversa does not show any traffic at all when I use tcpdump to monitor eth0 in the domU or the vif interface in dom0. It seems that basic connectivity of the vif interface and eth0 in the domU does not work. Any tips on how to debug this problem?

CentOS 5 Networking :: Static Ip - No Network Connectivity

Oct 27, 2009

I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).

Networking :: Network Server (DHCP) - No Connectivity To Modem

May 4, 2010

Basically, I wanted to use the Bootp (PXE) protocol to boot a machine (my laptop) from my network instead of using USB/DVD boot medias to reinstall if need be. My router being a piece of crap, I couldn't setup the DHCP server to allow PXE packets. Confirmed from the manufacturer that it is not possible. Well for a $140 router, you would expect the opposite. Anyways, here I am with a small machine setup with Slack, no desktop environment (only CLI) and connected to my router (which I deactivated the DHCP) so the machine can act as a DHCP server. It works very well. However, I would like to install a few other utilities into that machine and for them to work, I need to put the machine between my cable modem and my router. Basically, here's the topology from outside):

Internet (ISP) --> Modem --> DHCP machine --> Router (no DHCP - acting as a switch) --> computers & printers

The problem is that I cannot connect to the modem from the computers on the network. Also I cannot access the internet (go on the WAN side) from the computers. From the computers (namely my laptop), I can ping the router, but cannot ping the interface where DHCP broadcast. Also I cannot ping the modem. From the router (using the web config page), I can ping the DHCP broadcast. From the DHCP machine, I can ping the modem. In the DHCP server, I setup the eth0 (the interface where the modem connect to) as a DHCP assigned IP so it can obtain the IP from the modem. The eth1 (the interface where DHCP broadcast) is static. All my machines obtains a IP from the DHCP machine without a hiccup.

I have a Dell D420 that I successfully upgraded to Ubuntu 10.10. Everything looks fine except there is no LAN or wireless working. I upgraded the BIOS to the latest version (A06) and there are no proprietary drivers listed under System/Administration/Additional drivers.

when I plug the LAN cable into the 420, the indicator cycles for a long time but eventually displays the red exclamation mark.

Slackware :: Wireless Connections - Valid Ip Address, But No Network Connectivity?

Apr 8, 2011

I'm having making network/internet connection with my laptop. I have:Toshiba 1415 S173laptop
NetGear WG511T pcmcia card using madwifiNetGear WPNT511 pcmcia card using windows driver via ndiswrapperSlackware 12.2In both cases the card is recognized, and I can get a list of access points with iwlist.I can set the card to connect to the desired access point. I can use dhclient to get an ip address from the remote dhcp server. This works, the card is assigned a valid ip address on the desired network.Once I do this, however, I cannot access any network resources, no Internet, and no other devices on the network can see, ping, or access my laptop. It does this with with both cards, using madwifi or the windows driver via ndiswrapper.

Fedora Networking :: Flaky Internet Connectivity - Network Inactive In NM Panel

May 28, 2011

I just installed F15 on a laptop that previous had F12 working well. During install, it finds my wireless card and seems to set it up fine. The full install ran with the wireless active without any problem that I could see. Now, when I start up, I see Network Manager tells me that the wlan is active, but it doesn't show my specific network. If I click on the NM tray icon and open up the panel, my network is shown but it is not "active".

I can double click on it and it will become active - shows the little globe next to the antenna. This works fine for about 2 web pages worth and then FireFox 4 stops being able to find web pages. If I go back to the panel, double click on my wireless network (which looks like it is active already), and reactivate it, I can get the page I was looking for in FireFox, but within a couple of minutes it will stop.

Likewise with yum, while I'm installing software, I'll occasionally get errors like this:
[URL]: [Errno 14] curl#6 - "Couldn't resolve host"
If I reactivate my wireless network in the NM panel, it continues fine. Other computers/phones connected to this network seem to work fine. Is NM known to be problematic in F15?

OpenSUSE Network :: WiFi Internet Works Fine But Limited Connectivity Elsewhere?

Feb 22, 2010

I'm using 11.2 with KDE.

I can connect to the Internet on my WLAN just fine (using Opera) and can dload torrent files (using the same).

However, I have had trouble accessing some community repositories in the past, cannot synchronise with an NTP server (annoying since my battery is low and time and date are reset most reboots) and cannot use the lyrics function or Wikipedia function in Amarok. Nor can I connect to the net using Firefox (though conqueror works just fine...) I cannot download torrents on KTorrent either.

It seems that there is some sort of 'permission'/connectivity issue.

Ubuntu Networking :: AR5001 Chipset - Wireless Networking Randomly Loses Connectivity And Can Not Regain Connectivity

Jun 25, 2011

Wife's laptop has AR5001 Wireless Adapter laptop model is Toshiba Satellite A215

Problem : Wireless networking randomly loses connectivity and can not regain connectivity, the only apparent solution is a full power down , this is not even certain to work. The card works under Windows, she hates Windows. (I love her for this) I know it's not faulty hardware , because it will work for days on end under Windows without problems.

Things I've tried : madwifi drivers (any and all versions available) : These increase stability of the signal and seem to delay the inevitable however it still happens. When using these drivers the only option is to unload them modprobe -r then reboot then remove them again and re add them. It makes no sense why this works, and if I don't remove them prior to rebooting it will not work.

ATH5K drivers : These are pretty much junk, results are unpredictable at best, sometimes it will work perfectly for a few hours, sometimes it will not work at all. Nothing is repeatable, I can't seem to force whatever condition is causing this. rfkill does not show the wifi being blocked (hard or soft), unblocking it anyway does nothing, only way to make this work and it's iffy is to fully power down wait 5-10 minutes turn it back on and it MAY decide to work.

Firmware update : Updated the Toshiba BIOS to the latest version of the firmware 2.0 no joy here either. Same issue both sets of drivers.

Tried different distros and kernels : I've tried Mint 9, 10 ,11 ; Ubuntu 10.10, 10.04 , 9.10 and 11.04 (which is currently installed) , Fedora and OpenSUSE. All are giving the same problems. I have also tried a slew of different kernels no joy from any of them (I'm not at the computer with the issue now I will post exactly what kernel versions I've used when I have access to the machine).

Another useful bit of information, the hard switch to disable/enable wifi WILL disable it but turning it back on does absolutely nothing. The hotkey does nothing at all. The bios does not have an option to disable or enable the wireless card.

I will also post the typical lsmod , lspci , iwconfig all that good stuff when I get back to the computer in question. I'm probably just going to buy a PC card for it and give up on that one, but this is driving me insane and I would really like to see it resolved even if I do replace the hardware.

Ubuntu :: Teamspeak 3 Server Connectivity - Unable To Get Network Setup Correctly To Allow People To Connect Externally From My LAN?

Jan 21, 2011

I have Ubuntu 10.04 x86 installed, trying to get teamspeak 3 beta30.I have followed this guide: http://robert.penz.name/296/howto-in...u-10-04-lucid/

And can not get my network setup correctly to allow people to connect externally from my LAN. I have forwarded every relevant port I could find to the computer hosting TS, I forwarded them first as their respective protocols, and then as the combined UDP/TCP. I tried Forwarding single port numbers, and then port ranges.I have also tried uninstalling selinux.I have tried connecting directly to my cable modem with the server.I had this working perfectly three months ago with all the same software, using the same guide I listed above.The only thing I can imagine has changed is my operating system itself with system updates.

My network looks like:

Comcast cable modem--->Netgear WNR3500L Router----->Ubuntu 10.04 x86 desktop edition

what else I could possibly check? I can connect to and manage the TS server fine using localhost:9987 or 192.168.1.x:9987, it just wont allow any connections from outside the network.

OpenSUSE Network :: Wireless Card Realtek 8187 Connectivity - (Firefox) "the Server Can't Be Found"

Dec 3, 2009

I have a Toshiba Satellite L305-SP6944C, Pentium Dual Core 2.16, 2GB RAM, 160GB hard drive, DVD-RAM UJ880AS, display 15.6 TFT widescreen, ethernet Realtek RTL8101E/RTL8102E PCI Express, WLAN Realtek RLT8187, Opensuse 11.2 and KDE 4.3.1. Installation was OK and finally the wireless card is working... but I don't have conectivity bacause in the browser (Firefox) appears a message saying "the server can't be found"

I follow the howto write by Swerdna. With ndiswrapper I install the XP driver for RLT8187, KnetworkManager is in charge of connections showing both eth0 and wlan0, the wireless sign of router Dlink DIR-280 is OK, in the dialog box of network connection I put the mac address of the wlan card but I think that is not the problem.

Other thing that I missed is that I don't find boot.ini at any directory to add modprobe ndiswrapper in the boot sequence, in etc/init.d/ appears a "boot" file, is this file that I have to change to modprobe ndiswrapper??

Ubuntu Networking :: Different Connectivity Under Different Kernels?

Apr 19, 2010

I use a laptop with a built-in WiFi card (Intel PRO/Wireless 3945ABG [Golan] using iwl3945 module). It's OK but sometimes is not very stable, occasionaly it simply dies and I have to reboot. It was even worse but I improved it by applying a new driver.I also have a very nice USB WiFi card (D-Link System DWA-140 802.11n Adapter [ralink rt2870]). It's much better and faster.

So the problem is that in Ubuntu 9.10 (2.6.31) I can use only the built-in one. The other one (D-Link) also works but I can't make it connect to my router. The built-in card connects to it but the D-Link even does not list it among possible connections (but it lists other possible connections which I do not want to use).The funny bit is that this problem disappears when I use an old Kernel (2.6.28-18 ) : both cards work fine and can connect to the router at the same time (obtaining different ip's). I then disable the built-in one and happily use the external card.

Unfortunately the old Kernel has issues with sound and video, so I would like to use the latest Kernel with the external card. I tried WICD but it didn't change anything.I can add that under the old Kernel the USB card is used as a ra0 device while the new Kernel lists it as wlan1.

Ubuntu Networking :: DWA 547 Connectivity Stability?

Apr 4, 2011

I have an issue with my Dlink DWA 547 802.11n PCI adapter, I'm under LUCID fully updated.I have no trouble connecting to any wireless but after a few minutes I'm loosing the connectivity strenght (getting ping reply from my router that vary from 2ms to 200ms). But as soon as I'm rescanning the network using the command (sudo iwlist wlan0 scan) everything is fine (constant 1-2ms ping). I'm using wicd as network manager. I have tried to schedule a job in crontab to launch every 10min a network scan command, but didn't succeed to have it working, morehover I don't think that's the good way.
