General :: Wireless Card Stopped Receiving Packets - Slackware?

Mar 6, 2010

I just installed Slackware 13 with xfce and everything went well (eventually). At first, my wireless didn't work, but then I found /etc/rc.d/rc.wireless.conf. Everything was working, and I was happily surfing and downloading packages.But then one day... It just stopped! I tried to ping google, and it could send packets but not receive them.I'm connecting through an unlocked network in my building, so I guess it's DHCP (thats what i set it up with the first time 'round

Slackware :: 13.0 - Wireless Card Stopped Working After Reconfiguration

Jan 30, 2010

After doing a reconfigure of my wrt54gl router, trying to activate WEP encryption, and then finding WICD wouldn't connect, and returning to the original config on the router, now wicd won't reconnect the wireless card. Here's the wicd.log entry from the attempt to connect:

Code:
2010/01/30 18:40:46 :: ifconfig wlan0 up
2010/01/30 18:40:46 :: iwlist wlan0 scan

General :: Networking - Interface Stops Receiving Packets As Seen By Tcpdump

Mar 30, 2011

I have a linux box with two interfaces: eth0 is a builtin and eth1 is a USB-LAN.

There is an IP configured on eth1.

eth0 is up but no IP is configured. This interface is used for sniffing with tcpdump.

The problem is that eth0 frequently stops receiving packets -- my tcpdump captures are empty, and if I look at the interface stats with ifconfig, I can see that no packets are received.

If I bounce the interface (ifconfig eth0 down; ifconfig eth0 up), it starts receiving packets again.

Networking :: Receiving UDP Packets - Default Gateway

Apr 11, 2010

I have a computer with two interfaces: a fixed connection (eth1) and a modem (ppp0). My goal is to receive UDP packets from both connections concurrently (using the recv() function). The problem is, that the received packets reach the application only when the default gateway is set to that interface's address. For example, if I set the default gw to be in the eth1 subnet, only packets from eth1 reach the application. Other packets are received in the interface (checked using tcpdump), but they seem to be blocked somewhere. The policy defined in iptables is "ACCEPT" for all incoming packets, with no rules at all. I would like to know how to overcome this problem, and anyway how is the default gateway related to incoming UDP?

Fedora Networking :: Wireless Card Stopped Working?

Jan 9, 2010

I have a relatively new F12 install (one week old) on which I got my wireless Broadcom card working using kmod-wl-PAE. It was a very easy process - not really a process just yum install kmod-wl-PAE.

After a few updates, I notice that the wireless card stopped working. I assumed maybe there was an update that conflicted, so I did a reinstall of kmod-wl-PAE and it worked again immediately.

Then I started installing compiz-fusion. Immediately after, wireless is broken again. So I yum erase kmod-wl-PAE and then yum install kmod-wl-PAE and it works again.

Now, only slightly later that same day, wireless stops working more or less randomly and I cannot get the reinstall of kmod-wl-PAE to fix it. So I uninstall, disable compiz-fusion, shut down, and restart the computer to try again. My thought is that maybe along the way my autostart compiz or something about compiz is causing the wireless not to configure properly. When I restart, wireless is working. Without kmod-wl-PAE installed:

yum info kmod-wl-PaE
Loaded plugins: presto, refresh-packagekit
Available Packages
Name : kmod-wl-PAE
Arch : i686

[Code].....

One, how is this even possible, and two, what is going on with the wireless working, not working, working, not working?

Ubuntu :: Wireless Card Stopped Finding Network (10.10)?

May 8, 2011

desktop has been running Ubuntu 10.10 just fine since December. Today, the connections menu shows nothing but "Wireless Networks: disconnected." My laptop is inches away and has a full connection.I'm not sure what diagnostic tools I have at my disposal. The one thing I've been able to do is lspci. The relevant output of sudo lspci -v | less is:

Ubuntu Networking :: Wireless Card Stopped Working After 10.04 Update?

May 11, 2011

Well, I have an issue with my wireless card in Ubuntu 10.04, my wireless card model is:
the D-Link WIRELESS N 150 DESKTOP ADAPTER DWA-525. I was already successful getting it to work by using the RaLink driver suggested here and following the instructions in their readme.But after a system update I performed through Update Manager (in which I guess the kernel was updated), the device stopped working completely. The wireless icon remains(in the top panel), but it displays a red exclamation mark next to it

Ubuntu Networking :: Intel Centrino Wireless-N Card Stopped Working?

Feb 23, 2011

I have a new Thinkpad t510 laptop with an intel centrino wireless N card (no bluetooth). I installed ubuntu a couple weeks ago after I got another hard drive in the expansion bay. I have the drive partitioned into two sections, 250gb for file storage, and 250gb for the linux OS. Currently no other OS is installed on the other harddrive.

I have had everything perfect for the past couple weeks, but once i installed some updates today, my wireless fails to work now. Just some general info that you might ask me, lspci | grep Network, returns

00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Furthermore, on the top right of my screen, my wireless is grey'd out and says no network devices available on hover.

[Code]...

Im trying to connect to my college wireless network. I have looked a thinkwiki and no one has posted any bugs. Any ideas on getting it working again?

Slackware :: Wireless Stopped Working On Laptop

Nov 25, 2010

I'm running Slack 12 on a Thinkpad T60 and my wireless has stopped connecting to my wireless network at home. I'm using wicd for network management and it was working up until yesterday. I don't know what to do to track down the problem, so I'm looking for advice to do so.Other wireless devices in the house can still connect, so I don't believe my router is the problem.

Ubuntu Security :: UFW Stopped Logging Blocked Packets / Solution For This?

Mar 17, 2010

On April 10, 2010, I upgraded some packages on my Ubuntu 9.04 server. This included an upgrade to "ufw 0.27-0ubuntu2". I rebooted the server, and all appeared to be fine.

Now I've noticed that UFW is not logging blocked packets since that reboot. It used to do this. It is still logging the allowed packets that I've configured it to log.

Here's what a "ufw status verbose" says code...

Slackware :: Can't Use Wireless Card

Jul 12, 2011

My computer is ThinkPad SL400 and the wireless card is AR5001 wireless network adapter (Atheros Communications Inc.). I now use slackware13.37. I can't make the wireless card work and the indicator light is always out. In Windows7, the wireless card can work. Doesn't the kernel 2.6.37 support ath5k? I find the webpage [URL], but I don't know whether I should download the relevant driver or the kernel has already possessed the driver and the only thing to do is activate it.

Slackware :: Good Wireless Card That Works With System Out Of Box?

Mar 7, 2011

I have an older laptop (Dell Inspiron 4100) on which I have installed a minimal Slackware system, and have just managed to get wireless working by using a Linksys Wireless-G card (WPC54GS) and installing the b43 packages from the SlackBuilds site.

Unfortunately, I am experiencing system freezes ... and if my Google searches are correct, these are related to the firmware driver (b43 stuff).

I wonder if anyone can recommend a good wireless card that works with Slackware out of the box ?

Slackware :: USB Wireless Card Recognized But Cannot Connect To Network?

Dec 17, 2010

Hi I have istalled a D-Link wireless adaptor - with the help of this forum.

It is up and running - the light flashes and lsusb identifies it correctly, so does iwconfig.

I can, however, not connect to the network, and I noticed the following errors on boot up.

Trigering udev events: /sbin/udevadm trigger -- type: failed /etc/rc.d/rc.M: wlan0 Error for wireless request; "Set Nickname" (8BIC) information; "Any ESSID" Set failed on device wlan0; operation not supported.

Lower down I get

Starting rt2870 drivers . . . /etc/rc.d/rc.inet1: wlan0 information "Any ESSID"
Error for wireless request "Set Nickname" (8BIC) set failed on device wlan0 : Operation not supported

I have on two occassions seen sugstions to use wicd, but how do I use that?

Slackware :: Wireless Card Currently Idle / Can It Be Used As Access Point?

May 17, 2011

i'm running slack 13.37. my machine has a "generic" wireless card which is currently sitting idle in it, since i used a wired interface for internet and local networking (i used the wireless interface for a while, but for what i need it wasn't a reliable or stable enough connection). my question is, can the idle card be used as a wireless access point on a separate subnet? if so how?

Ubuntu :: Star Tech Pci420usb Card - The Card/devices Just Stopped?

Jan 23, 2011

I recently installed a startech PCI usb expansion card...All went well and all external devices connected show up without a hitch. However a day ago The card/devices just STOPPED. I rebooted and no avail. Rebooted a second time got a IRQ 19 failure error. Then on a third try It showed up and worked fine... This has happened twice. Here's my IRQ print after running cat /proc/interrupts

CPU0 CPU1
0: 132 3 IO-APIC-edge timer
1: 0 146 IO-APIC-edge i8042
7: 1 0 IO-APIC-edge

I am assuming that the second to the last entry is the pci usb card. Is there a way to home in more deriectly to find and troubleshot the problem and see if its module or IRQ?

Slackware :: Network. No Rc.netdevice. No RX Or TX Packets?

Aug 8, 2010

I created a similar thread last week in the networking section but only got one response. I was hoping to get a little more help here as this forum helped me tremendously to partition my hard drive safely. That was over a week ago, and ever since then I have been struggling with setting up my network. Here is what I have done.Basic set up with netconfig. I selected DHCP and followed the directions on the screen.ifconfig -a shows eth0 with no RX or TX packets at all, but at least it showed me information. If it was not detecting my card (which is compatible with linux), it would have said no device found. correct?

dhclient eth0 just hangs there for half a minute until I can add a command again.dhcpcd eth0 times out.I read (in slackbook chaper 5.2.1) that the correct kernel module may not be loaded. So I opened rc.modules with pico and went to the netdevice section. In slackbook it said to find my device and uncomment it.... but I cant find it! (I have an atheros ar9285 in my stock compaq CQ61 laptop) I also opened rc.netdevice and it was empty..It seems like the more I learn about the network, the more lost I get. I keep hearing that configuring a network on slackware is easy, am I just missing some simple step?Also, whenever I startx, akonadi gives me an error. I also get another error saying that it could not parse XMS file. Is that just due to my lack of an internet connection at the moment?

Networking :: Firewall - Allow Packets Coming From Internet After Authenticating And To By Pass Packets Generated From Internal LAN?

Feb 8, 2010

i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it.

i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?

Ubuntu Networking :: Internet Dataflow Over Wireless - Get 1 Or 2 Ping Packets

Jun 4, 2011

I'm running Lucid (10.04), dualboot vista, but I'm having some issues with my wireless USB dongle. Previously (in a different) location, the network wasn't showing in my wireless network tab, and that was never resolved. But now I'm in a new place, and what I'm finding is that my network is showing up in the networks tab, and I can select it, enter the PSK, and it starts to interrogate, but never seems to manage all the way through to getting internet.

Im not sure whether the machine is able to connect to the network, but not the wider internet, or what. The only indication I'm getting is that its connecting for a length of time, then gives up. I have managed to get the update tool pop up - so I'm not sure if thats an indicator of some internet connection or not (presumably it only generates the list of packages to update when it can connect to the net and see what updates are required...) I believe its also managed to get 1 or 2 ping packets through to the internet. I'm driving a belkin N-wireless USB adapter, N10117.

OpenSUSE Wireless :: Intel PRO/Wireless 5300 AGN Stopped Working For 11.2?

Jun 6, 2010

The wireless on my 64-bit openSUSE-11.2 installed on my Dell Studio 1537 laptop stopped working some time back (possibly more than a one or two months back). I just discovered this last week when on business. I have not used the wireless under openSUSE-11.2 for a while so I am not certain what broke it, but I am suspicious of an update. I note openSUSE-11.3 milestone-7 works great with the wireless (on a liveCD). I note possibly two related threads, although I note no failed request for firmware in my case:request for firmware file 'iwlwifi-5000-2.ucode' failed [INTEL 5300 AGN] [OPENSUSE 11.2] - openSUSE Forums, and I see another thread here: Suddenly No Wireless Network Card - openSUSE Forums... but I can not tell if what I have is the same problem, so I did not add to those threads. In my case I can scan for the network, and see the SSID. An ip address is assigned. But a ping does not work.

Some details, the wireless is:

Code:

04:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection [8086:4235]
Subsystem: Intel Corporation Device [8086:1121]
Kernel driver in use: iwlagn
In terms of installed apps:

Code:

rpm -qa '*wireless*'
wireless-tools-30.pre8-5.1.x86_64
wireless-regdb-2009.09.08-2.2.noarch

[code]....

I know the router wireless network is good, because I can connect to the router via wireless with another laptop (old Fujitsu-Siemens Amilo 7400M with older Intel wireless), and the router wireless also works with this Dell Studio 1537 PC (with same hardware) but with openSUSE-11.3 milestone7 version.
