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.

When I connect my Debian PC to my WiFi router my PC doesn't get internet if other devices are connected to it .
When i disconnect those devices and connect my Debian PC only then my PC connects to internet but other devices connected to it later do not get inernet connection.
When I connect my Debian PC using LAN Cable to the same router all devices work fine.

I have internet from KabelBW (cable modem which doesnt require any username,password,dns,mac...) they gave me a cisco modem, I connected it with my asus router and it has been working fine since today! when I woke up I turned on my lap top and loged in skype, but I couldnt open google, then I tried yahoo..nothing! I havent made and changes yesterday! I dont know what is wrong! I am new to ubuntu and I dont know what to do! when I connect directly to modem I have internet it works good, but when I connect through my (LAN or Wireless) router I cant view web pages. I have tried to google for the answer but all the answers are for windows OS versions! I tried to restart lap top, and the router 100 times but nothing!

I am having problems while testing out squid proxy server. I just can't get it block anything. So, I'm running Debian lenny on my Virtualbox and Squid on it. I'm having windows 7 on virtualbox too and they can ping each other and the webserver on debian (apache2) is working fine. The problem is i can't get squid to block webpages. I have the correct settings on windows proxy settings, but i'm not so sure about squid. I want to block lets say www . xxx. com for example. So I add to the main configuration file:

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.

I have installed network controller driver(iwlwifi) in debian jessie and connected to wifi, but I could not connect to any web sites. I installed network-tools and input "iwconfig" it did show a wlan0 there.
Then I opened resolv.conf ,but there were 2 resolv.conf in my /etc,one contains "search lan nameserver 192.168.199.1",one contains "nameserver 8.8.8.8 nameserver 8.8.4.4".
I changed the content of the first one to 8.8.8.8 and restart networking,but I still could not open pages with wireless network.
And I open the first one again,and it changed back to 192.168.199.1,and an extra line "domain lan"above the line"search lan".

WiFi on this laptop worked fine for a few months then went out; after a reinstall of ubuntu (since 9.xx had come out since then anyway) the wireless still refused to even see networks, let alone connect to them; under Wireless Networks in the NM, I just see a greyed out 'disconnected'. This got me to thinking that it may have just been a hardware issue, but I find that hard to believe. Anyway, here's the pertinent information:
Started off with an lshw command just to see if a network adapter is even listed as being connected: `lshw`
Code:
id:
network:1

product: PRO/Wireless 2200BG [Calexico2] Network Connection[code]....
As an addendum : I found this driver project but they claim to require a 2.6.8+ kernel; a quick `uname -r` shows that mine is 2.6.31, and an `apt-cache search linux-image` reveals that to be the highest available from repos; do Debian/Ubuntu distros not use more recent kernels or is this an Ubuntu-specific kernel naming scheme? If so, to what would it be comparable? I'm hesitant to try to install this and change my firmware if it's likely I'll be borking something.

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?

What additional info should I give?PS. Sorry if the problem was already addressed, I am trying to find the solution on the web - but no success. Also 1-day discussions on ru-net forums were not successful, unfortunately.

I just installed Fedora 14 i386, and Fedora can see the wireless network just fine. I try to connect and nothing happens. It asks for the PSK constantly (yes, I promise I'm entering it correctly), even after I enter it correctly (I guarantee). I've searched around here a bit, but due to my limited knowledge in linux system I can't figure it out

I love using wheezy but i keep having to take my computer downstairs to hook it up to router through ethernet, i need it to connect through wifi and stay connected.
heres my problem, if i use live image and connect to network its fine but during installation process it gets to the network configuration, it will keep disconnecting at dhcp and if i try and continue it gives me the error packages broken due to it not staying connected.
MY WIFI CARD IS A TP-LINK WDN 4800
if i try and just do a net install then it doesnt show my wifi network.
it uses in both cases ar93xx atheros driver for installing, i just need to know how i can try and keep a stable connection over wifi so it can install over wifi so i dont have to keep taking pc downstairs to install it.
i done something that stopped me being able to login into wheezy i was left at black screen with blinking command line, i have reverted to mint debian until i can get a stable connection over wifi to install wheezy again.

Loaded Debian Jessie (x64) and when adding printers, can see my printer which attached ok to my RaspberryPi and can print thru it, but can not attach to my Jessie box. If it adds, it can't see it or reports printer is busy, tried every config I could find on the web. Previous versions of Debian I loaded the canon print driver separately and loaded the cnij(?) filter. Do I still have to do that? Is there a trick to getting a network canon to work?

I've been using my upstairs computer with no problems recently up until this evening, when I rebooted it did an automatic scan of my disks, so I left it to it's thing and when I came back ubuntu had successfully booted, and had seemingly successfully connected to my wireless network as usual.
I've been through the wireless troubleshooting guide, paying special attention to sections 4 and 6 but to no avail, while I'm apparently connected, and have been assigned an IP by my router I'm unable to access anything outside my computer, including the router itself. This happened before, however I solved it by reinstalling ubuntu, and I'd rather not do that again!

I'm facing a strange problem after upgrading my Ubuntu to 10.10. After I start up the system, the wifi is not getting connected by default (which was getting connected automatically in the earlier version). So I right click on network manager and click on 'Enable Wireless' option and it gets connected. So far so good. Now I close the laptop lid - it goes to sleep mode and after it wakes up, the wifi never gets connected. When I right click on the network manager icon, the 'Enable Wireless' option is disabled! I have to reboot my machine to get connected!
Here are the details:

I've noticed that switching to Ubuntu about 6 months ago has made it noticeably more difficult to use the free wifi at my school. When I had Windows 7 on the same laptop, it was much easier to establish and maintain a connection. I know it's not the hardware. My question is: is there some security setting that makes it difficult to use public wifi on Ubuntu? Also, I don't have this problem at home on my WPA2 home wifi network.

I have an Ubuntu laptop connected by wifi to a Cisco router and a desktopUbuntu PC conneted by wire to the same router. I would like, if it's possible to connect them without using the Internet (I mean what I want it's not just communicate between them using SSH over the Internet, for instance, but also communicate without connecting to the Internet). My DSL connection it's 4 Mb/s while my router can work up to 100 Mb/s so I would like to take advantage of these 100 Mb/s to transfer files between the two computers instead of using 4 MB/s

I acquired an old Compaq Evo laptop and installed Kubuntu on it. Bought a second hand wifi card, a DEXLAN IEEE802.11b (Having Googled to check it would work with Linux).
It detects wireless networks fine, and is able to connect to open ones, but I can't log into the home network with the password which works fine for Windows laptops.
I've tried every configuration of the router I can find, and followed the advice at https://help.ubuntu.com/community/Wi...untu#EasySteps but with no luck. It just asks for the password over and over again without connecting.

I've recently salvaged a computer I found gathering dust in the basement and decided I'll have it running on Fedora (I have a summer studentship coming up that needs Linux use so I thought I'd best start learning!). Following a clean install, Fedora can see the wireless network just fine. I try to connect and nothing happens. Half of the time it will ask for the PSK (yes, I promise I'm entering it correctly) and the other half of the time it will just stop. When it does ask for the PSK I enter it (correctly) and it will ask me again... and again.

Today I got my laptop back after its motherboard was replaced (soundcard failure) and I am having problems connecting to the internet. Connection to the wifi network is succesful, but Pidgin is not connecting ("SSL Connection Failed") and I can't view any webpages in Firefox. I loaded up Win7 and everything worked fine, connecting to the same wifi network and using the same proxy settings ("No Proxy").

I have a Dell Mini 10v with a fresh install of latest Ubuntu Netbook Edition. I have enabled proprietary drivers in order to get the WiFi card to work and managed to connect at home, starbucks etc. Good stuff.
For some reason I can detect but not connect to the WiFi at work - I get prompted for the pword and after entering it the WiFi indicater will pulse for a while only to return to the pword prompt. yes, I have the right pword and can connect my iPhone and other laptops. I am really puzzled by this and really need to get on the WiFi at work - wired connection works.
my colleague has the same dell model with windows 7 installed and is able to connect fine - I really don't want that @@@@ installed just to get WiFi. I know password entry error is the obvious solution but I connect new windows devices to it routinely and had other people try too.

I was wondering if there's any way for a laptop to be both simultaneously connected to a wireless network, while at the same time acting as an ad-hoc network with local access to serve as a wifi connection for my mobile device, which would be ssh-ing into the laptop and using local resources.

This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.

So I recently upgraded from Debian 5 to Debian 6 and now for some reason I cant SSH into my server FROM my server. All of the following fail with the same error:
[URL]
They all come back with: ssh: Could not resolve hostname 127.0.0.1: Name or service not known. I never actually tried this before upgrading so I'm not sure if its caused by the upgrade, but I would like to get this fixed. Also, ping with all of the above hostnames fails as well. I can SSH in from other computers and I can SSH out from the server. For whatever reason, I cant SSH from the server to the server though.

When I connect my laptop to projector, its not detecting. But when I log-off and then log-in it automatically detects the display. I tried function key, but its not working. I am using Debian Lenny also. Also several others with different version of ubuntu running on different laptops reports the same problem. I tried searching net, but couldnt find a good answer.It would be helpful if some one explains what exctly is happening and an easy work around for this problem.

Previously, I issued a wakeonlan command to my sleeping debian (wheezy stable) server from (a mac) within my home network and then ssh in no problem. Worked like a charm. I could put it to sleep again and wake it up etc. Perfecto.
However, for some reasonI can now only ssh in once the server is rebooted (by physically switching it off then on again). If I put it to sleep then wake it, it does wake up --- however, ssh cannot then resolve the hostname:
