Debian :: WiFi Connection Cause Squeeze To Crash / Resolve This?

Aug 21, 2010

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.

Does anyone know what's wrong and how to fix it?

Debian :: Squeeze Crash When Copying Files?

Sep 9, 2010

I'm running squeeze on i686, my last update was this morning (9/9/2010). Running the stock kernel 2.6.32-5-686

My PC keeps crashing when copying files. The monitor displays the desktop, but the mouse doesn't move, nothing responds and I can't even ssh in to debug it.

This happens when copying files using nautilus and the command line. I'm trying to copy files from my local hard disk to an nfs drive which is mounted in my system and has been working fine for years.

how to debug this after a hard reboot?

This has only just started happening, last night was the first time.

I have a problem with Debian Squeeze. I have installed Squeeze and after that I installed LDAP according tho this guide: [URL]. When I log in and try to start Epiphany or Iceweasel nothing happens. I tried installing Chromium, but this program starts with the message "Chromium didn't shut down correctly". After some waiting it comes with another messages saying "Page(s) unresponsive.

Debian :: WiFi Not Working At All / Resolve This?

Mar 16, 2011

I just installed Debian only to be confronted with a problem. My wireless internet won't work. If I click the internet thing, under "Wireless Connections" it says "device not managed", btw my internet works and it did when I had Ubuntu, so nothing wrong in that department.

Debian Configuration :: Networking: Connected To Wifi, Webpages Won't Resolve?

Oct 2, 2010

I just installed Debian with the latest testing iso, and I'm having problems connecting to the web via browser. I can ping hostnames (i.e. google.com, debian.org, etc.) from the terminal and it resolves just fine, but if I try to load a page from Iceweasel or Epiphany it says the page won't load because it can't resolve the hostname. Can someone tell me what I'm missing?the detail that I'm running amd64. I've checked iptables and found no entries, and for good measure I flushed it to be certain. I also checked resolv.conf but that looked normal, just a nameserver entry pointing to my home router. I'm new to Debian, but have used Linux for years, and I'm genuinely stumped. I'm sure the solution will smack me in the head for its simplicity, but nonetheless I need at least a shove in the right direction.

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.

Debian Configuration :: Slow Wifi In Squeeze With Atheros Ar928x?

Debian Hardware :: Wifi: Ar9271 In Squeeze: Compat-wireless Or New Kernel?

May 22, 2011

I'm trying to get a TP-Link TL-WN821N WiFi USB dongle to work. I bought it because I thought it was based on the Atheros ar9170 chip (which is supported in Squeeze), but I've since learnt that it was based on the ar9271, which is only supported from kernel v2.6.36 on. I've read several threads on the subject, but I'm still confused about what I should exactly do. Since it is stuff that can potentially make the partition unbootable, I prefer to ask rather than to tinker.

I've read that upgrading the kernel would do the trick. The Liquorix kernel is especially recommended in one of those threads. However Liquorix only supports Sid and Testing. Apparently, you still can install it by fetching gcc 4.5 from the Sid repository, then install it... I'm a bit wary of screwing things up though... Another route appears to be the compat-wireless tool. I've downloaded the latest 2.6.32 release of compat-wireless (see here), but there's no reference to the ar9271 in the README. Is it appropriate nevertheless (they refer to an online list of supported drivers that was updated after the release... not sure what to make of it)? Otherwise, can I install the so-called "bleeding-edge compat-wireless" with a 2.6.32 kernel? BTW, I know that I'll also need the ath9k_htc firmware to be installed.

Debian Configuration :: No Wired Connection With Squeeze And RTL8139?

Jun 9, 2011

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:

Debian Hardware :: No Wlan / Lenovo T61 / Squeeze / Cannot Get Any Wireless Connection?

Jun 23, 2011

i have debian squeeze installed on my lenovo t61 notebook with intel wireless 3945 firmware.

i've installed the firmware-iwlwifi package but cannot get any wireless connection.

i'm using the fluxbox dekstop with wicd network manager.

i've searched around on the debian user forum archives and the internet but have yet to find a solution for this. it seems most people have just installed the firmware-iwlwifi package and then wlan was working.

i had ubuntu installed on this machine before with wlan running, so i know that there is nothing wrong with my hardware.

Debian Configuration :: Unstable Internet Connection Squeeze - Realtek Adapter

Jul 14, 2011

I'm going to start using Debian as my desktop system rather than Ubuntu since I'm not really liking all the crazy eye candy and just wanted a fast and simple system. My main problem is networking, I guess I'll start off with my system specs and other information for problem solving.

My specs are:

- Intel Core i7 2600K CPU
- Gigabyte Z68X-UD3P-B3 Motherboard
- 8GB DDR3 1600Mhz RAM

I have a Realtek RTL8111/8168B Ethernet Adapter builtin to my motherboad which I am using, I could only get a basic connection, by basic I mean that it allowed me to connect to my local area network but not the internet. I then modified /etc/NetworkManager/NetworkManager.conf to change to managed=true this allowed me to use the internet, but the problem is, that it is a very unstable connection, the speed is very slow and it drops a lot! I have to carry on running /etc/init.d/network-manager restart twice to get my connection back, which lasts for about a minute.

output of lspci | grep -i eth

07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

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.

Code: Select allquant@debian:~$ lspci

Hardware :: USB Headset Causes Crash In Fedora 14 - Resolve It?

Feb 13, 2011

So this is really weird - my Logitech headset that I've been happily using with Fedora since Fedora 10 has suddenly started freaking out Fedora 14. Everything was fine until last night, I was listening to some music and it was getting late so I decided to switch to headphones. It was ok for half an hour then, when I think I (maybe, I can't be sure) knocked the USB plug in its socket, Fedora just froze. No coming back.

After a minute of plugging, unplugging, various attempts to get out of Gnome, etc. I gave up and held down the power button. Machine came back fine, I shrugged thinking it was 'one of those things', plugged in the headset again and *bam* - instant freeze! Weird. It's never done this before.

So I restarted *again* - this time plugged the headset in a different socket, same problem. Fedora froze as soon as I plugged it in.

Looking at the logs, here are some excerpts up to the crashes, in case they help. I think this is the lead-up to the initial crash code...

Again, right after those lines Linux froze and the log just tails off.

What's even weirder here is there doesn't seem to be any consistency, a repeating pattern before the crash - but it is always the instant I plug in my headset.

Debian Configuration :: 8.0 With GNOME 32bit - WiFi Connection With WPA2

Apr 12, 2016

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:

Code: Select allauto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid AndroidAP5
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk 18[...]

After this I tried to execute the follow command :

Code: Select all/etc/init.d/networking restart

And the system returns:

Code: Select all[  ok  ] Restarting networking (via systemctl): networking.service

but nothing else happens. The internet connection doesn't work. The Android phone not detect PC connection IN.

Debian Hardware :: Intel WiFi 7260 Ac - Slow Connection

Jun 27, 2014

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)

$ dmesg | grep iwlwifi
[    1.784455] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X

I'm not sure why modinfo iwlwifi only lists firmware iwlwifi-7260-7.ucude while in dmesg you see iwlwifi-7260-9.ucude loads.

Ubuntu :: Laptop Crash - Black Screen / Resolve This?

Mar 18, 2010

My laptop was shut down normally, but when it restarts - it just shows the very first image (Toshiba something....) which is the screen where it says what commands to type to get into bios.

After this - the screen shows nothing more. All black, except some faint (extremely faint) lines...

I don't know - my first thought was that the screen itself was caput, but since it shows the initial screen - I guess it's not...

Debian Configuration :: WiFi Connection Stuck At (Setting Network Address)

Oct 9, 2015

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:

Code: Select all01:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)

This is the problem:

I installed Debian with non-free firmware because of this chip.

Red Hat / Fedora :: Increase Detail Of Messages Logfile To Help Resolve A Intermittent Crash?

Mar 29, 2010

My server is running Red Hat 4.1.2-44.I am having an issue with it hanging (website doesn't respond, can't connect via SSH (it's a remote server)) after 4am on every 3rd Sunday or so.A reboot is required to get the server responding again.I have checked every logfile I can find and found nothing that helps me. The thing I have noticed is that some of these log files start afresh after the reboot so my initial thoughts are that it is a logrotate issue or something similar.

The last activity I can find before the reboot (at 8:32) is in the logfile /var/log/cron:
Mar 28 04:22:01 crond[9356]: (root) CMD (run-parts /etc/cron.weekly)
Mar 29 08:32:39 crond[3884]: (CRON) STARTUP (V5.0)
