Debian Configuration :: WiFi Connection Which Then Is Sent To A Wired Connection
Sep 22, 2015
The situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.
I have installed Debian squeeze 6.0.1 using the CD1 of the i686 version (kernel 2.6.32.5) on my compaq presario sr1799es desktop. My machine has a ethernet card RTL8139 (RTL-8139/8139C/8139C+)(it has no wireless card). I can't connect to internet with debian.
I can connect to internet in this machine using windows xp. I also checked with the Puppy linux 5.2.5 version (with kernel 2.6.33.2) using a usb memory and I had success connecting to internet by dhcp. I already checked lots of forums with related questions but I couldn't find a solution for my problem. I'll show you the output of lspci and lsmod !grep 8139 commands:

I have 2 connections, wlan and wired, and I'd want to have a few websites (in my browser) to connect through the wireless connection while other go through the wired rj45 connection. s it possible? (without unplugging the rj45 cable...)
I just installed the lastest stable Debian (gnome) today and what I was most afraid just happened: my laptop's wifi isn't working properly, it isn't turning on. This had already hapened on livecd.
In the laptop's chassis leds, the wifi led apears as green. When I click to turn on the wifi, as shown on the picture the button, quickly disappears and appears again not seeming to have any effect at all at turning on the wifi but not showing any error either!
Picture :
What's interesting about the wifi not working is that in the installation process I was able to connect to a wifi hotspot and it connected to the internet fine!
Now after installation was complete and my system did the reboot, I was no longer able to connect to the internet using wifi.
My wireless card is Atheros AR9565 and my LAN card is also Atheros.
Here is an output of lspci and lsmod which may have some leads about the problem.
I'm using Debian 8 with GNOME 32bit. I installed a driver with ndiswrapper for my old D-Link DWL-G650M.
If i using the default network manager to connect with a Free wifi the connection works fine. But if the wifi have the password the connection doesn't work.
I. using my phone Android to create the Router-Wifi like this:
SSID: AndroidAP5 Password: BillyBob Encryption(the one allowed): WPA2 PSK
With network manager gnome is impossible to connect. I changed in setting the password type with WPA2 but the system doesn't connect.
I tried to connect manually and i updated the file /etc/network/interfaces as the follow:
I have Debian 8.2 with KDE 4.14 and everything runs perfect, except for the internet connection. This problem happens randomly when I turn on my machine. Sometimes when the desktop loads, the connection is already settled.
But sometimes when the desktop loads, the wifi icon is still loading and keeps stuck at "setting network address". Since this problem happens randomly I really don't know what is happening here. My wifi chip is this:
I'm trying to use these cookie cutter rules that I found. But every time I use them, after a few seconds my wifi connection goes dead. The exception was the first time I used then. Which lasted me a couple of minutes.
By dead I mean I can no longer open a webpage or ping google.

The problem I have is when I install 10.10 I get no wired connection my wifi works great, just no wired connection. I don't have WiFi where I am right now. It works fine when I run off the dvd , but when I install it i get nothing. I have tried static ip, reinstalling, reinstalling drivers. Don't know what else to do. I have a Dell Inspiron 1720. The ethernet is a broadcom 440x.
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
[code]....
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
I've been reading around, but not had much success at all in trying to share the internet connection from my laptop to my phone.all the articles i read refer to earlier versions of Ubuntu and the packages they mention have become obsolete, according to the apt-get tool.im not that new to Linux, but my networking probably isn't up to scratch.if anyone could help me, that would be great, im using Ubuntu 10.04 at the time of writing.
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
i am using ubuntu and with all versions i have one pretty anoying problem. My wired connection sometimes lost connection and i can't reconnect for 3-10min. sometime longer. Technically everything is allright. With win7 i never had such problems. Any solutions how to fix this problem?

I have been using this fresh Debian 8.2 install for 3 days without any network problems.
What I did this morning :
- Booted in my windows partition and rebooted immediately just to remove the system from the sleep state - Mounted a NTFS hard drive and copied some file to my .wine drive_c
Thats when I noticed that my connection was down.
I verified all the physical layer. My laptop has access to the internet tried to connect on an another router with eht0, changed the wire, nothing worked.
It seems like the interface can't get a dhcp ipv4 address even when I try to force is with dhclient, I get no offer when my laptop works just fine.
- Booted on my windows partition without changing any connection and my internet was working. - Booted back on debian still not working...
As a random thought I purged the firmware-realtek package and rebooted. Ethernet works fine now??
Fresh Jessie installed this morning with KDE. Wired worked fine during installation and initial boot. Reboot after package installation and only wireless is working right now. I did install the realtek firmware as part of my normal package list.
This is /var/log/syslog when it stopped working, and hasn't reconnected since. Cable is fine as it was working perfectly with a live Ubuntu shortly before I installed the system with Debian.
I'm using a wired ethernet dongle due to my machine not having an ethernet port, however it sometimes drop connection, how can I diagnose whether if the dongle is faulty or my system is having trouble maintaining a connection.
I'm using Debian-Squeeze, and the command "uname -a" results in "Linux debian 2.6.32-5-amd64 #1 SMP Sat Jul 24 01:47:24 UTC 2010 x86_64 GNU/Linux". The desktop environment is Gnome 2.30.2.
My problem is wireless connection causes the system to crash. Here is the detail: my university uses a WiFi service that we have to enter our ID and password in a certain web page in the browser to get access to the Internet, while the WiFi signal is automatically picked up. My laptop crashes each time I connecting to such wireless network. But back home, when connecting to my own WiFi, everything is all right.
As the only thing I can do when such crash happens is to press the power button to force the computer to shut down, I've gathered no more information till now.
I manage to install debian on my flex 10 (lenovo), but now internet is not working, i can see the network, but even being able to connect to them i can't access the net...
I have Squeeze running gnome well.It connect to my WFI AP automatically.I installed window maker yesterday .After I enter the window maker desktop, I found no internet connection.I run a network tool shortcut in th eapplication menu.This program is the same of my gnome desktop.I change the setting to make it automatically connect to my AP but in vain.
I have search the web quite a while about issues with the Intel Dual Band Wireless-AC 7260 Wi-Fi/Bluetooth card. It seems plenty of people have trouble (or at least have had trouble) with it. I do have a working connection, device seems recognized etc, but it works only at a very low/annoying speed.I'm running Wheezy backports and I have firmware-iwlwifi ver 0.43 installed (from Debian testing).
Below is some system output Code: Select all$ uname -v #1 SMP Debian 3.14.7-1~bpo70+1 (2014-06-21)
My Debian Jessie system started to bug after a separate /usr partition being full. After redimensioning and various packages reinstalls I fall on this:
systemctl --user status Failed to get D-Bus connection: Erreur inconnue -1
My network configuration is in a weird situation, that I always need to run dhclient manually each time after a network connection is established. When my computer connects to a router, sometimes it won't get a valid IP, and it uses an automatically generated fake Internet IP. In this situation, it won't connect to the Internet at all. Sometimes it get a valid local network IP, but still cannot connect to WAN, and could only connect to my router's address (both through ping and through router's management webpage). In both situation, it can be solved by a simple dhclient run.
This is my /etc/network/interfaces file:
Code: Select all# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
I use Debian Jessie 8.2 and I am using a 3G connection using this modem => [URL] ....
The 3G connection works fine, except after 24 hours the connection drops and I cannot reconnect. If I reboot the computer, the connection will work again.
My guess is that my ISP gives me a new IP address after 24 hours and somehow my system cannot handle it.
How can I reconnect my 3G connection without rebooting?
I have already tried the following commands:
Code: Select allsudo service network-manager restart
Code: Select alldhclient -r eth0 dhclient eth0
Code: Select allsystemctl restart ModemManager
Results of journalctl and grepping my connection name (SFR)
Code: Select allsept. 22 17:58:19 ark1 NetworkManager[512]: <info> Policy set 'SFR Web / Prepaid 1' (eth0) as default for IPv4 routing and DNS. sept. 23 18:17:07 ark1 NetworkManager[9446]: <info> new connection /etc/NetworkManager/system-connections/SFR Web * Prepaid 1 sept. 23 18:17:08 ark1 NetworkManager[9446]: <info> Auto-activating connection 'SFR Web / Prepaid 1'.
[Code] ....
As you can see sept 22 at time 17:58 is when the computer started up. And roughly 24 hours after it failed to reconnect.
Also I should mention that there is a script to run the command:
Code: Select allsudo service network-manager restart
if the computer cannot ping a server, ie if the connection is lost.
More journalctl info when the system tries to reconnect:
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
My HWaddr doesn't look that well :) 'ip addr' prints this result:
Code: Select allroot@i67svof:/var/www# ip addr 1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
These are the last lines in /var/log/syslog:

I have been tol that for debugging purposes it is often useful to have a serial connection to a computer. I have some diskless workstations thats freezes during boot. I guess X has someting to do with this, but I'm not sure. Since the workstations are diskless, syslog is not stored locally so I cant se what is happening after the NiC stops working. When the worstation freezes, screen is going black, all lights on the keyboard turns on, lights on NiC is going black. It is not possible to ping the workstation.
I have configured a RaLink wireless card to connecto to an 802.1x network. I connect by selecting the network, and the i give the credentials(username/password). How do i configure Debian to automatically connect to this network when a session begins?
I have installed GNU/Linux Debian on my computer (desktop) and i have ubuntu installed on my laptop. Now I want to start the ssh connection between both the computers. I want to make Debian as server and Ubuntu as client. Please can you guide me with this (installation and setup). Also the key values of the configuration file (ssh_config & sshd_config) are expected.
Alright, I was playing with the VPN capabilities in KDE4 on Squeeze AMD64 on my personal laptop (see my signature) and found it very easy to create a VPN connection and connect, but that's it. I made a VPN tunnel to one of my client locations as a test, but could use rdesktop to get into the server. Then I realized I couldn't ping the server either. I also lost all ability to browse the web and everything while the VPN was up. Upon checking ifconfig as root, I saw that it created "ppp0" and hat it had pulled an IP from the client network, but all of my networking capabilities were gone. What gives? What is it that I am missing?
