Debian Configuration :: WiFi Connection Isn't Working After Install?
Mar 27, 2016
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.
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'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.

I am new to linux and decided to use Debian. I installed it on my laptop and have a few problems.First one is my WIFI.
Laptop type: HP Omen 15 Wifi adapter: Intel Wireless 7260n rfkill list output:0: hci0: Bluetooth Soft blocked: yes Hard blocked: no So wifi is not displaying Kernel: 3.16.0-4-amd64 Debian version: 8.4 gui: LXDE URL....
But they see in rfkill list the adapter.How to make this adapter work?I did this with no result:
nano /etc/modprobe.d/blacklist.conf in file add: #Fixing a bug that prevents wifi from working on HP Omen blacklist acer_wmi
I would like to learn more about Linux, but before experimenting I need a working system. The plan for me is to run this as my native machine with vms on top of it with other OS.
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...
About an hour ago i did an update on my Debian Squeeze. After the update was completed my LAN connection stopped working.. now i have to connect my computer to my router with a usb cable instead with my ethernet cable.. also, on the network connection, on the wired network section it says that the device(ethernet) has not been managed..
I've been using Ubuntu and Mint for a few years now, and I want to try Linux on my HP Stream7 Tablet. I was very excited to learn that Debian 8.0 and later has support for 32 bit UEFI on 64 bit Processors and went ahead and installed the multiarch version of 8.2. It works, but I have no GUI (Just a command line) and no WIFI connection. It seems the GUI didn't install and the WiFi card is not supported. I have found a driver for the wifi card but don't know how to install this driver. URL....
I have no idea how I managed this, but I am able to connect to the internet but NetworkManager doesn't show any connection. This means that until I kill it, I cannot log in with Pidgin, because it is waiting for a connection.
Do I disable NetworkManager completely or do I try to make it recognize that I am connected to the Internet? If the latter, then how should I go about? (Please let me know which files I need to show you, because I know I've messed around with a couple).
I have installed Suse 11.4 recently and I'm trying to run the wireless connection and doesn't works. Details: card: pro/wireless 2200BG Calexico2 driver installed (as console said) kernel driver:ipw2200 hwinfo:
I have tried to connect by traditional method with YAST, just recognized one network call "Hotel Riga 228", but doesn't connect. Also I have tried to connect with Network Manager but this application doesn't recognize ANY w. network.
I just recently installed Ubuntu 9.10 on a dell laptop. My WiFi connection that I've been using on the same computer for years is not working when I log on. However if I run the burnt image cd and choose the option "Use Ubuntu without making any changes to your computer" I am asked if I want install proprietary drivers. If I activate one "Broadcom STA" I can connect to the wireless connection in my house. When I am using the version installed on my laptop it doesn't ask me if I want to install the drivers and it doesn't even find them when I go to hardware drivers under system. So to sum it up I can get connection when I run Ubuntu from the cd but not when I run the Ubuntu on my laptop.
I should be able to access xfinitywifi hotspots. /etc/network/interfaces and /etc/wpa_supplicant.conf. I don't want to use NetworkManager for this connection.> iw dev wlan0 scan
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.
My pc is aser aspire 5735z. I have acer nplify 802.11b/g draft-n wlan but i can use wifi on debian what i have to do ? Do i need driver or firmware? how can i solve this problem ?
I did a netinstall earlier today (latest version, amd64) on my Dell XPS laptop and ended up with a minimal installation because I couldn't connect to the internet. Now I'm trying to get online without a desktop environment.
I have an Intel Centrino 1030, so I downloaded and installed the firmware [URL].... with a usb, then rebooted. My searches have turned up a lot of instructions involving a utility called iwconfig and wpasuppliant, but these are apparently not installed. I don't really know much about it, but my /etc/network/interfaces file looks rather empty:
Code: Select all# The loopback interface auto lo iface lo inet loopback
Shouldn't there be something like wlan0 there? The network card does show up with lspci
I've been installing multiple versions of ubunutu over years and now I better understand why I faced always problems with wifi configuration on these different baselines : Debian root of course.
Now on Debian 7.4 : The Broadcom BCM4313 driver is not loaded by default (not free product) for my wifi card. This is stated thru the UNCLAIMED declaration
I have a netgear wg111t that is running with ndiswrapper. It has an atheros chipset, but calling it ath0 didn't work.
Heres /etc/network/interface :
# 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
I have finally weaned my laptop from network manager by setting up my /etc/network/interfaces file. # The loopback network interface auto lo iface lo inet loopback
wireless automatically connects to my home wireless network (linksysn). But suppose I wanted to take this laptop to the coffee house where they have free wifi. I am assuming that my wireless will not automatically connect to any other wifi hotspot except linksysn. So how do i set it up to roam like NM did?
To exploit the guessnet capability, I have configured my WIFI so that ifplugd can auto connect WIFI after boot.The access point is hidden, and I have provided all the required info in my /etc/network/interfaces file
Are USB WiFi adapters more likely to work in Linux than other WiFi adpaters like PCI cards etc?Im just wondering if they can use a generic USB class driver rather than having to have one for the specific chip set?
After to install Debian Sid, i can't to connect to my network. When i launch lsmod, ath9k is present so the module is enabled.I don't use network-manager-gnome, wicd and other, i modify myself /etc/network/interface. But even with this configuration, the wifi does not works.
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.
Using a USB ISO, I recently installed Debian 8.0 Jessie (64-bit, Xfce DE) to a new computer. I usually lose my Wifi connection after 1-3 minutes when donwloading/uploading at around max. speed 4 Mbps/512 kbps. Sometimes it will last 15+ minutes.
When lightly browsing it can usually stay connected for 15-30 minutes. I have to disable and enable Wifi using NetworkManager to connect again. If I remember correctly, there were problems with the Wifi connection even during the installation of Debian.
This Wifi USB adapter works fine on my old computer with Debian 7.7 (32-bit). No problems with the Wifi connection yesterday on my old computer during 10+ hours of activity.
This Wifi adapter also works fine on this new computer when I boot from a live USB (Rescatux 0.30.2) downloading and uploading at max. speed for 1+ hour.
I already tried some suggestions I found online, but they didn't work:
* changing Wifi channels between 1, 6, 11 in my router settings * changing WPA-WPA2 to WPA2 in my router settings * ignore IPv6 in NetworkManager * change probe_wait_ms from 500 ms to higher value by adding Code: Select alloptions mac80211 probe_wait_ms=1000 or Code: Select alloptions mac80211 probe_wait_ms=3000 to /etc/modprobe.d/mac80211.conf and rebooting * disable Power Management for Wifi adapter (not supported) * ...
I can also post the output of commands from Rescatux or my old computer if needed.
Output of commands on Debian 8.0 64-bit (I edited out some info, MAC, ...; not sure if that is important):

A friend gave me an HP Mini 110 that I can actually use in some situations. I installed Debian 8 with LXDE. It runs well except for the expected lack of driver for the Broadcom 4312 wireless chip. I installed wl using the method shown at [URL] ....
It works fine except that it takes very long to set up WiFi at boot (1 min 30 sec or more every boot--this is a rather frail Atom processor) and the WiFi reception seems poor (65% from an excellent router at 25 feet).
I'm thinking of getting a Panda 300Mbps Wireless N USB Adapter (reportedly using the Ralink RT5372 chipset) and removing the Broadcom driver. I have 2 questions:
1. Could I expect the Panda not to slow my boot time so much? I'm not knowledgeable enough to tell whether there is stable kernel support of this device, although the manufacturer says repeatedly that it works with most Linux distributions.
2. To remove wl is Code: Select allmodprobe -r wl the correct approach?
I've been using Debian for about 6-7 months now. I've had a bit of a major networking problem for the past 4 months or so that I've been trying to fix - specifically, it started when I upgraded to Jessie. I can connect to wifi just fine, and sometimes I can even use the internet for brief periods of time (exceedingly rarely). Then... nothing. No network access, period. I can't ping any outside servers, I can't ping other computers on my network, and I can't even ping my router. Pages I try to load just stay "connecting" for all eternity, network printing fails, and so on.
So after four months of searching online (I've read through way more wireless documentation than I care to say), I finally gave up and admitted that maybe I screwed something up during upgrade to Jessie (as a matter of fact, I did, I had to do the upgrade in two increments [somehow] because my root partition was too tiny by mistake) and I did a clean install. Since I had /home on a separate partition, I was able to keep all my user files, but all settings regarding networking were wiped. So after installing firmware-iwlwifi so I can use my wireless card, I tried connecting to wireless! Success! Then I tried connecting to the internet... success! Briefly. The next morning I tried using the internet again, and it failed in exactly the same pattern as before.
I don't know much about what's going on here, but here's what I do have available:
I do have to use firmware-iwlwifi, which I installed by doing apt-get install firmware-iwlwifi. I don't think it's an issue with the wireless card itself (hardware-wise), the laptop dual-boots Windows 7 (that I never use anymore), and Windows 7 is able to connect to the internet just fine. Connecting directly to my router by ethernet cable works fine, I have perfect internet/network access then.
I can confirm that my laptop is receiving an IP address and that it is using ARP correctly to get the MAC address of my router (I confirmed this by doing the arp command, it has the MAC address correct, I checked from another computer with my router's config page) All other computers on my network work perfectly with my router. To confirm the router/its configuration isn't at fault, I did a full factory reset of the router, but to no avail.
Out of curiosity I tried installing Wireshark (using an ethernet cable to download it) to monitor what happens when I try to access a webpage. I'm no expert on networking, but I noticed something out place when I compare a capture from the affected computer to a capture from one operating normally - there are a lot of STP packets showing up. I did some checking around, it looks like STP is involved in bridging and more complex networking setups (involving switches, for example)... but it shouldn't be found on a home network, especially where there's no bridging whatsoever. These STP packets don't show up on packet captures done from any other computer. I've attached a packet capture from the affected computer here, since the forums won't let me attach a .pcapng file.
Here's the output from a few commands I ran during past troubleshooting sessions:
