Debian Configuration :: WiFi Stops Working
Jun 28, 2015
In a hp pavilion 15 Notebook PC with Debian 8.1.After two hours or so wifi stops working. Network-manager does not give any indication of failure but some times a yellow question mark.
rfkill list wifi gives:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
ifconfig gives:
eth0 Link encap:Ethernet HWaddr 8c:dc:d4:7b:c2:0e

I'm running Debian server 5.0.6 and the latest stable version of Apache. I am hosting a website and it will stop responding after an unknown amount of time. In order to make the website work again I have to run /etc/init.d/networking restart. The server is running a static IP address and is not resetting when the website goes down. I don't know where to start looking.

Testing distribution. Installed Linux 3.0 but left 2.6.32 on as backup. When I boot into the old kernel, wireless mostly works OK, but never when I boot with the new kernel.
Results of dmesg|grep wlan0 on 2.6:
[ 22.005102] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.196774] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.644779] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 30.688053] wlan0: direct probe to AP 00:19:5b:06:9f:ba (try 1)
[ 30.694053] wlan0: direct probe responded
[Code]...
Noticing the Access Point looked like it needed the MAC address, I ran iwconfig wlan0 ap <MACADDRESS> and sometimes it will work, and wicd can connect to the access point. But sometimes the command fails to run.

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 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.
lspci
Code: Select allquant@debian:~$ lspci

i am getting some troubles with WiFi. I got a Lenovo G550 with a BCM4312, at first i found some troubles making it work but i managed to find a proper driver and it is working "fine" Every 5 minutes or so my WiFi freezes and internet stops working. I don't get disconnected from the network, but until i don't reconnect to it, internet will not work.
Rare thing is, i realised that this happens ONLY when my notebook is plugged in. When it's working on battery, this does not happen. If i use it on battery it works for 30-40 mins (or more) and 3 minutes after i plug it in, it just stops working. I'm using Ubuntu 10.10, if there is any information i could give, just tell me. I also have a Windows partition and this does not happen there, either plugged in or on battery.

Previously my wifi has worked just fine in 10.04, but as of recently I keep losing my connection after leaving my laptop on for a while (and this happens sooner and sooner each time, used to be daily, now it's every few hours), I can no longer see any networks at all, and I have to reboot to get it working again. I haven't even installed or removed any packages lately, so I'm not such what might've caused this to break all of a sudden.

I'm using a Vaio TT, which seems to use an Intel 5100 WiFi chipset, and a Linksys WRT54G2 (firmwares 1.0.1 and 1.0.4), ubuntus 10.10 and 10.04.
Wifi works fine out of the box. However if the other vaio tt in our office (running windows 7) comes online, my laptop stops being able to make new connections. It WILL stay connected to chat servers, and downloads SOMETIMES continue to work. However all new HTTP requests / ssh connections / rdp connections / pings fail. The laptop still appears to be "connected" to the wifi network.
This may also happen after an undetermined amount of time without the extra vaio. It is not solved by reconnecting or rebooting. Once the extra vaio leaves the building, everything works fine again. This problem does not happen at all if I boot into windows.

I have a logitech c310 webcam. When I open cheese, I get a blank. Also my wifi adapter stops working - it doesn't show up on lsusb anymore. How do I fix this? How do I get both my wifi adapter and camera to work at the same time and how do I get my webcam to work? The adapter is D-Link DWA-125. Here are the outputs for lsusb:

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

I found that in many occasions ice weasel browser stops functioning (not responding) and the only way out is by killing the process.secondly, the process ID is actually firefox!! and no ice weasel process, cause ice weasel is just another name to firefox; and this stopped me from installing firefox.Unfortunately, when I used Konqueror which comes with every linux distro, it gave the same problem.

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:

I use my debian machine for masquerading, packet filtering anilar for a tiny network.It runs the latest debian testing.Every now and then (i am talking about weeks) the connection to my internet stops working.ifdown eth0; ifup eth0 brings it back.The other interface (eth1) is never effected.The odd thing is, there are no warnings, no messages .. nothing.I cant find any entry. Nothing in the logs, nothing in dmsg and no kernel panic.The only way to find out when it might have been happened is to search in several daemons log files,to find out when their first error connecting to the internet occurred.I ran memtest without any results.The nic is e1000 compatible.

I am currently using Debian Testing, managing my wireless connection with NetworkManager and the Gnome nm-applet. Both have just been updated: network-manager from 0.8.1-6+squeeze1 to 0.8.2-6 and network-manager-gnome from 0.8.1-2 to 0.8.2-4.On installation of the new packages, I have no problems. However, on a reboot, I can no-longer connect to any wireless connection. I am not prompted on start-up for the password to unlock the Gnome keyring and when I left-click on the nm-applet icon and then click on a network to connect to it, nothing happens.I do not think this is a driver or NetworkManager daemon problem. If I run "nmcli dev wifi" or left-click on the applet icon, NetworkManager seems to scan for wireless networks properly and returns a list including the one I wish to connect to.

I have a Lenovo Thinkpad R500, and recently I recently upgraded it with a Crucial SSD as well as 8 GB of DDR3, as I had a blank SSD installed, I decided to switch from Mint to Debian and see how I like it. I'm using Debian 8 with the MATE desktop and so far it's been quite a pleasure to use, besides one small thing.
Every 5 to 10 minutes, DNS resolution stops working completely. I can ping IP addresses as well as connect to websites by IP address just fine, however I cannot resolve hostnames. The problem exists regardless of whether I'm connected to my router via a wired or wireless connection. It is not occurring on any other computer in my house and didn't exist on my old Mint installation. If I disconnect from my home network by either unplugging the Ethernet cable or flicking the WIFI switch on my laptop, and then reconnecting, I can resolve hostnames again, albeit only for another 5-10 minutes, when DNS stops working again.
I was originally using DHCP and my ISP's DNS servers, but switched to my laptop using a static IP address and Google's DNS Servers at 8.8.8.8 and 8.8.4.4, the problem persisted after this change.

I am having a problem which I am having a hard time finding out about. To start I am running Debian 8.0 on a laptop through an external Seagate 2TB HDD that I connect via USB 3.0. My problem, basically, is when ever I use Linux for an extended period, for what ever reason, some of my icons disappear and my terminal breaks. More specifically, say I were to try to shut down the computer at the time of the problem the icons and text telling me which option is which, in xfce4, are gone. Then if I click on the would be shut down button it just goes to a black screen with a white underscore and hangs there. This symptom is probably due to the fact that commands in the linux terminal stop working. As in, if I were to type ls it tells me there is no command (something like that) and tells me some folder directory that I think is where bash is located. I wish I could be more specific with some of these details.
Anyway the only way for me to "fix" it is to just do a hard shut down, then upon reboot it clears the orphaned nodes. Also, before, when I installed linux several weeks before I never noticed this issue, if it was ever present. However, now that I have seen it, I have since tried re-installs of debian to no avail. I have a feeling it could be the external hard drive, but that notion is not based on any evidence.

After installing KDE USB keyboard and mouse won't work. They are added to /proc/bus/input/devices though.
I also tried to install Gnome; same thing.
I took #usb-devices and they were there also..
But #usbhid-dump did not generate anything to screen.

Have a very unusual problem that I am looking at troubleshooting. Only problem is I don't know where to start.I have the following wireless usb device:
Code: Select allBus 002 Device 007: ID 050d:845a Belkin Components F7D2101 802.11n Surf & Share Wireless Adapter v1000 [Realtek RTL8192SU]
Now it is fine when browsing the web, but whenever I download a large file/game from Steam it becomes unresponsive and stops working.I have noticed it happens whenever the download is maxed..which at the moment is at around 5.4mbps on steam.Never get a warning...just internet stops working...no pages can be displayed...The connection never disconnects.I can only get it working again when I unplug it and re insert it back in again.
Things I have tried:
- Returning it to the shop and getting a new one (didn't fix it).
Code: Select allzerocool@hal9000:~$ uname -a

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
Code: Select allÂ
sudo lshw -c network
 *-network UNCLAIMED
    description: Network controller
    product: BCM4313 802.11b/g/n Wireless LAN Controller
    vendor: Broadcom Corporation
    physical id: 0
[Code] ...
Unclaimed means : no driver found (no kernel association)
So I installed the driver located in the non-free backports by adding this target into the repository
Code: Select alldeb http://http.debian.net/debian/ wheezy main contrib non-free
and install :
Code: Select allsudo apt-get update && apt-get install firmware-brcm80211
sudo modprobe brcm80211
Check seems OK :
Code: Select allsudo lshw -c network
 *-network
    description: Wireless interface
    product: BCM4313 802.11b/g/n Wireless LAN Controller
    vendor: Broadcom Corporation
    physical id: 0
[Code] ....
I can't connect with wlan0, it doesn't work. I found information here regarding WPA2/PSK wifi configuration on debian : [URL] ....
so I added this setup to my interfaces file an got :
Code: Select allauto lo
iface lo inet loopback
allow-hotplug wlan0
iface wlan0 inet dhcp
 wpa-ssid Hznteam-Datacenter
 # hexadecimal psk is encoded from a plaintext passphrase
 wpa-psk 12345678901234567890123456
It's worth ! no more wifi network are detected and ifconfig gives no ip address allocated :
Code: Select allwlan0   Link encap:Ethernet HWaddr 78:e4:00:4e:49:a3Â
     UP BROADCAST MULTICAST MTU:1500 Metric:1

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
# The primary network interface allow-hotplug eth0iface eth0 inet dhcp
# Wireless Setup auto wlan0 iface wlan0 inet dhcp wireless-essid linksysn
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?
