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.
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.
My server gets ddos attacks. I dig into access logs and I saw that attacker ips doesn't have valid requests headers, like their browser application info or requested url info.I want to close those connections immediately, and if it's possible block those ips for a time period.Can I do that with Apache and iptables?I searched on the internet but couldn't find useful results. Probably couldn't search for the right words.
What I want is quite simple, I have my PC running Linux Mint 5 (Elyssa), and I would like to connect it to both an internal network, which has a file/print server, another machine and will soon host a small cluster. I also have a wireless router connected to the tinterweb.
The thing is using my ethernet I want to connect to the internal network whilst simultaneously using my wireless to deal with the internet, I want to keep the internal network off the net as it really doesn't need to be connected. I can connect to my internal quite happily and also my wireless but not both at once.
When I attempt to connect to a wireless network, the network manager asks me for the network's password, then says 'setting network address' for 20 or so seconds, then asks me for some random Hex or ASCII key in the same type of window I put the password in (Secrets for Noel -- KDE Daemon). Since a key is already typed into the window, I press OK, which then causes the network manager to go back to 'setting network address', then the window pops up again and keeps repeating itself.
I'm running Opensuse 11.4 with KDE, and my driver is ath9k. I don't know much about linux so please don't tell me to 'recompile this' or 'change this setting' without explaining how to do it. Please help, I've been unable to connect to wireless in OpenSUSE for 2 weeks now.
Every single time I enter the network manager to edit connections is crashes on exit. I am running opensuse on an Asus eee PC 1000HE with an Atheros network card. The crash report follows :
As an extra point. I wish I could disconnect individual networks instead of just disabling networking to disconnect. I think the newer version of the network manager does this.
I have just installed Ubuntu 10.10 64bit on my laptop Toshiba Satellite A665-S6065 and I can connect to wired network but I can not connect to wireless network "Network Connections disconnected". Im following this post http://ubuntuforums.org/showthread.php?p=6183681
1. Machine Brand and Model (PC/Laptop): Toshiba Satellite A665-S6065 2. Wireless Brand, Model and Wireless Chipset:
I am running Ubuntu 9.04 as a partition with windows 7 on a acer aspire 5742, I would like to connect to the internet in Ubuntu, wirelessly, but I am unable to turn my wireless on in Ubuntu, and network manager says "no network connections available". I have the following network adapters:
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??
We use procmail to reformat and filter email messages sent from many lead capture websites where the clients enter their reply email address manually.When we receive the message at our application we send a welcome email, and receive back the Undeliverable Email message where the clients entries are invalid, but I would like to be able to kill messages with undeliverable email addresses on our mail server before they are delivered to our application.I have found discussions on filtering masqueraded addresses, but since the IP of the sending system is not related to the entered client's email address, this does not appear to help. I would think that it should be able to query the email server to identify if the address is valid.
I have a problem on internet connectivity. Let me explain. I'm using webkit for the browser, and when I try to connect to google, it does not connect. But if I use the ip address of this, 209.85.129.147, everything works. First of I had a suspicion from DNS but it seems ok. Because when I try to ping google, it is working again. I'm using an embedded linux, this problem on a MIPS platform, not PC. But I think there should be some settings onto webkit and this should be same with PC platform.
I installed Wicd from the Slackware DVD and was successfully connecting to the internet for the past few weeks.I do not know if the following caused my problem or if it is something else that I did:All of a sudden (probably something that I did) the wpa_gui screen started to appear on my desktop. I just closed it.Today, in a moment of stupidity, I said "Who needs this wpa-gui thingy?! I know, I'll just use pkgtool to uninstall it. Then, if I need it, I'll just use pkgtool to reinstall it!" So, I did. After my next reboot, you guessed it, no wireless.
Wicd seems to do everything it used to do, except connect. I get the error msg "Connection Failed: Unable to get IP address." I see my 'connection' listed and it is still set to "Automatically connect to this network" but it doesn't.So, is it the wpa-gui app that I 'uninstalled' or is it something else that I might have done?
I am trying to connect to the net wirelessly using Slax off my USB stick. I did the best I could using the wireless configure tool but Firefox will not surf - no connection. The configure tool shows that I am 'partly' connected in that it shows signal strength in green but I noticed that there is no entry for IP address. Am I suppose to know this and enter it? In LMDE, I see the IP as 192.168.2.10 and other addresses. Do I need to enter this stuff?
I have a problem with 32Bit Fedora. I have it installed on my desktop pc, and it works, but in my laptop it doesn't. On my laptop, I have 64Bit, but wanted to reinstall and use 32Bit instead. Whenever I try to install 32Bit, the loading bar finishes, then the screen goes black, and enters the terminal, blinking rapidly, spamming mtrr 3 not used. I've tried a few things to fix this, but I haven't had any luck.
I have another similar problem with 32Bit on my desktop. It is working right now, but yesterday I installed a NVidia driver, and the mtrr 3 error occurred, forcing me to reinstall, without the NVidia driver.
EDIT: I tried
X -configure
Then i ran
X -config /boot/xorg.conf.new
The errors that show up are these:

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
I believe I have the wireless card installed properly and wicd sees the router. When I try to connect I get an error "can not obtain IP address" Output from iwcongif and lspci is.
dillan@dillan-desktop:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions.
I'm using Ubuntu 9.10 and I recently changed certain settings of my router. After that ubuntu isnt able to obtain IP address from this wifi network. I've tried to connect with win 7 and OS X and both of the OSes are able to connect to the same wifi network. I tried to connect ubuntu to another wifi network at school and it connected successfully.
I have installed Fedora 10 on my A860 Dell Vostrol Laptop with AR242X Atheros Wireless card. Wireless card worked out of the box and i could detect wireless network and connect to it. But i have a problem that, my wireless connection is not able to get IP address from the DHCP server. Please help me out what can i do to get this working. I am using WEP security and authentication is open system.
I have windows 7 beta installed on the same machine and on that wireless network works fine so i am sure that there is no problem with the wirless network. I am using DIR-300 router from D-LINK. I tried to see packet log on wireshark and there i see that there is no reply to the DHCP discover message. Actually i don't see any RX packets at all. Which is not normal as there is traffic on the network.
I just installed openSUSE dual-boot with windows. Wireless works fine on windows. Only ethernet works on openSUSE. At first, it couldn't even find my wireless network. With my friend's help we experimented and tried everything to find the driver for my broadcam4312 driver.
Later, my friend some update from the official openSUSE peeps... Then, the wireless could my network. I entered in my password and then hoped for the best but then it got stuck on the Obtaining IP Adress part. I know I got the rite password.
I'm using Ubuntu 9.10 and for a while I had no problems connecting to the internet through the wireless network. But recently, my wireless connection started disconnecting regularly. Following an advice I found online, I installed linux-backports-modules-karmic, but after a reboot the wireless device stopped working altogether - it had lost its driver. Since then I managed to associate the device with Broadcom's STA driver, which I had been using before. But now, the wireless device cannot connect to the internet anymore. The network manager's output to /var/log/syslog indicates that the device cannot obtain an IP address. When I run code...
Objective is simply to be able to allow wireless clients access to my network based on their MAC address (I have about 10 WAPs around the country which I need to be able to manage user access centrally). Not interested in LDAP or dishing out keys/certificates etc.
I have been trying to follow the guide here. Sounds like it's exactly what I need but I'm not sure about a few things.
1) For each of the conf files am I supposed to be replacing everything currently existing in the respective file with what is suggested?
2) "raddb/modules/file" does not exist, so I assume I should use "raddb/modules/files"?
3) If I uncomment the line:
Code: #rewrite_calling_station_id under the "raddb/sites-available/default authorize{}" section, the radiusd startup gives me the following error: /etc/raddb/sites-enabled/default[69]: Failed to find module "rewrite_calling_station_id".
If anyone familiar with FreeRADIUS 2 could answer these queries I might be on the right path
I got ubuntu working fine on my netbook and wanted to play around with opensuse. I have it installed and everything works fine except my wireless connection. I have updated everything since the installation through a wired connection, that didn't help. I have read the stickies, but to be honest, I'm so new to this stuff I'm kinda lost. So my wireless network has a WEP encryption and I have entered that password as a 64 HEX Key in the Wireless Manager widget. It connects to the network and says is labeled as active, however there is still the yellow exclamation shield next to the connection. Firefox and other apps don't have access to the internet.
As promised the finished (pretty much finished) wireless script can be downloaded here the wireless_script is a diagnostic tool for wireless issues. It will return all relevant information to help diagnose a wireless connectivity problem, return connectivity stats and attempt to fix common problems such as blocks. It comes in cli - wireless_script_1.2.sh or gui - wireless_script_zenity_1.2.sh'
Let me know any issues you have with it. My contact details are in the readme.txt (also the wireless results.txt generated by running the script includes code tags for forums - so please copy and paste the whole document when pasting on forums to enable this function)
I have an open WEP wireless internet connection with a security key. KNetworkManager can never obtain an IP address from my wireless router, but I know that the router works because Windows can connect correctly and Ubuntu's NetworkManager can connection correctly. Does anyone know what is happening? KNetworkManager just asks for my security again and again and again after it fails to connect.
I do have trouble in configuring my wireless network,though i configured it as what Alien BOB say(http://alien.slackbook.org/dokuwiki/...ckware:network) and google some similar Threads.My latop is Asus F83vf, wireless card is Atheros AR9285 Wireless Network Adapter. The code when I run lspci command is code...
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?
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.
I've just installed a Slackware64-13.0 test machine with alienBOB's multilib packages. I'm running the stock kernel generic-2.6.29.6 with an initrd set up using mkinitrd.confEverything is fine except that I cannot build a right initrd for kernels 2.6.30, both the /testing one or a custom build: if I try, it will panic at boot with the "couldn't find a valid RAM disk image" error.On the same hardware, without multilib support, I was able to correctly build and boot 2.6.30 initrds.
