Debian Configuration :: Can Connect To Internet By WiFi But Won't Show Networks

Aug 28, 2015

I just freshly installed Jessie on my Dell Inspiron 5110, I configured the network on the installer and had no problem. I can browse the web, get updates and install software.

But I can't find new networks. It just show "No Networks".

lspci -vnn

Fedora Networking :: Networks Connects To Home Wifi Network / But It Will Not Connect To Internet

Aug 6, 2010

I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.

Debian Configuration :: Can't Connect To Wireless Networks At School

Mar 10, 2011

I installed Debian sid recently. I installed the B43 driver and wireless is working just fine at home and elsewhere. I can't connect to the wireless networks at school though. There are two networks, one is unsecured (and you have to enter your login details after connecting - I can't connect at all though), the other is secured. I was previously using Ubuntu, with network manager, and I have all my settings the same for the secured network as I did in Ubuntu. In Ubuntu I can connect to both networks just fine. In Debian I can't.

Debian Configuration :: How To Connect Wifi From CLI

Jan 7, 2014

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

Debian Configuration :: WiFi Connects But Can't Ping - No Internet

Aug 27, 2015

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:

Code: Select allsudo ifconfig
eth0      Link encap:Ethernet  HWaddr e0:db:55:b5:fe:06 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:12455 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7781 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000

Debian Configuration :: NetworkManager Doesn't Show (working) Internet Connection / Sort It?

May 14, 2010

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).

Debian Configuration :: Open WiFi Captive Portal With Only Local Net (No Internet / WAN)?

Apr 11, 2016

I am trying to set up a wireless 'test' box to use on a private club (11,000 acres). The initial tests won't need anything fancy, it will just be checking the visibility of a hotspot from a high-point in the middle of the property. But if it proves to have good visibility, later tests will be (hopefully) promoted by the club and made aware to members. I would like to set up a captive portal to redirect them to a comments page where they can post a quick message if they were able to connect ....

Most of the examples I see online of captive portal are based on having an internet connection and/or a NAT scheme set up. I just need a hotspot and a single web-page for these promotional tests. If possible, I would like to trigger any devices capable to suggest or otherwise open a browser to go to the promotional landing page ...

Also, one more quick question, this is to eventually be an 'open' internet for this test - most of the wpa set-up examples show using a passkey. Is making an open wifi as simple as not including the passkey or is there something else I would need to be doing?

Debian Configuration :: Auto-login And Auto-connect To Networks

Jun 3, 2010

I press On-button, Debian boots, logs in and automatically connects to the Wireless network AND! to my local pc via LAN. It runs an ssh server, so I can ssh into debian over internet and communicate with the local pc (send a magic packet).Here are my problems:

1) I don't how to log in automatically. This and this doesn't work.
2) I need a network tool that can manage multiple connections and has a reconnect feature. With the default network manager I cannot even connect to more than one network simultaneously although I have two network devices of course.

And I guess I can run all that in console mode, right?

Ubuntu Networking :: Won't Connect To Open (unsecured) WiFi Networks?

Jul 9, 2010

I have no problem with my wireless network at home, or visiting friends, but it won't connect to public, open, unsecured WiFi networks, eg hotels, trains, ships.I'm using Ubuntu v9.10, NetworkManager applet v0.7.996, on a Dell Inspiron 1750 laptop.If I left click on the NetworkManager, the available wireless networks are displayed and I can see the relevent open networks, named as expected and shown without the lock icon. I click on the relevent entry, watch a spinner for 30 seconds or so and then it drops off and I have no connection. This happens for "all" open connections.If I look at my defined Wireless Network Connections now, I can see, eg, "Auto Internet@Sea, Last used: never". Editing that connection:

SSID: Internet@Sea

Ubuntu Networking :: 10.10 - In Network Manager Can View Wifi Networks Fine But Cannot Connect

Apr 28, 2011

I have been an Ubuntu user for a year or so. My level is still ultra n00b but I am trying. Whenever I update Ubuntu there is always a WiFi problem, always. So now I am having problems getting wifi to work in 10.10. In Network Manager I can view wifi networks fine but I cannot connect. I tried with wicd also but I got as far as "getting ip" and then it would hang up.

lspci

Code:

Code:

Code:

I am not sure what driver I am using as I don't know how to exactly ID my driver. I know there is a way to ID the driver using airodump-ng but I have yet to find it.
I have a feeling this is a driver issue as one time I was able to establish a connection that then dropped a few minutes later. I have a feeling I should be disabling/removing the current driver and replacing it with ipw3945 or possibly a driver ndiswrapped? The problem is I cannot figure out how to remove the current driver.

I was going to switch back to 9.04 but I thought I would try to manually figure this one out instead of taking the easy way.

Debian Configuration :: Connect To Internet Through Wireless Card?

Jun 9, 2010

I am currently trying to connect to internet through my wireless card, after half day's effort I reached to this point:

/******The following error appears in the dmesg kernel ring buffer output:
ipw2200: ipw2200-bss.fw load failed: Reason -2
ipw2200: Unable to load firmware: -2
ipw2200: failed to register network device
ipw2200: probe of 0000:02:03.0 failed with error -5*********/

I found a solution from Intel website saying that the problem might be: "firmware in wrong location or wrong firmware version". So I proceeded to download the firmware and placed it in /lib/firmware. Also I tried to use menuconfig to enable loading firmware via hot-plug, but I think I have done something wrong when I was configuring the hotplug and firmware.

Debian Configuration :: Unable To Connect To Internet Connection

Apr 15, 2011

I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesnt get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesnt seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.

Ubuntu Networking :: Connect To 2 Networks And Access The Internet?

Mar 4, 2010

1) I connect to the internet on a wireless router from my isp.

2) I use an older router for my media server (pc) to my ps3. The router given to me from my isp is the only one I can use to connect to the internet, yet it has the worst UPnP support (ie: none).

So with this current setup, I have to disconnect from the the wired network to be able to access the internet. So how can I access the internet while still connected to the wired network?
