Ubuntu Networking :: WiFi Network Connection Started Failing

Sep 1, 2010

My ubuntu system has been running really well until this morning - software update prompt appeared on the screen, so I ran with it and let it do its thing. A while after this, my WiFi network connection started failing. I've tried rebooting and then it can take up to five minutes or more for the password (keychain) prompt to appear. Once I have typed in the password the network connection starts to work. Then cuts out. Works. Then fails again.

Fedora Networking :: No Wifi Network Connection After Upgrade F13 To F14?

May 29, 2011

Wifi network operated perfectly with f13. Upgrading f13 to f14 did not show any problems except for networking. It seems that the wlan0-link is not ready. Consequently no network information about adresses can be obtained. Tried with network tools to activate wlan0. No reaction Tried to deactivate Networkmanager and bring network up with

service NetworkManager stop
ifconfig -a
Then
ifconfig wlan0 up
dhclient wlan0

No reaction on network. The NetworkManager icon disappears which is understandable.

Ubuntu Networking :: Slow Wifi - But Fast Connection On Network Cable

Jan 22, 2011

I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.

What I have done so far:
(1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.

(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).

(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.

(4) I restarted my router and computer.
None of this helped.

I am using a Netgear WGR614 wireless router.

General :: Serve Ssh Connection To Wifi Devices While Connected To A Wifi Network

Jul 21, 2010

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.

Ubuntu Networking :: UFW Failing To Log All Connection Attempts?

Feb 17, 2011

I am trying to write a little port knocking daemon that needs to see every failed connection attempt on every port on the system. The primary way to do this (as the Wikipedia page points out) is to monitor the firewall log file. I am using UFW and reading its output in /var/log/kern.log. Typically, when UFW blocks something, it prints a little line like this:

Quote:
Feb 17 10:42:42 serin kernel: [323588.279588] [UFW BLOCK INPUT]: IN=eth0 OUT= MAC=00:0b:e6:00:85:96:00:09:5b:9f:41:a4:08:00 SRC=192.168.0.4 DST=192.168.0.8 LEN=60 TOS=0x00 PREC=0x20 TTL=49 ID=46945 PROTO=TCP SPT=56849 DPT=1723 WINDOW=5840 RES=0x00 SYN URGP=0

But it seems that whenever UFW experiences a significant "load" (my client sends eight packets over the span of about 25 seconds, not too significant if you ask me), it just kind of "gives up" after 10 or so attempts. Log messages stop appearing in kern.log. I know the packets are coming; wireshark confirms this.

It seems to me that a buffer of some sort is filling up, because if I give the system a breather and try sending my sequence again in, say, three minutes, it prints log messages for 10-12 straight attempts before giving up again. I've tried sending packets at longer intervals and reading from other logs like /var/log/messages, but none of this has helped. Does anyone have any idea why UFW would fail to log all blocked connection attempts?

Ubuntu Networking :: PPTP Connection Failing With LCP Timeout

Mar 6, 2010

I'm using Kubuntu 9.10, my pppd version is 2.4.5 and pptp is 1.7.2 I'm trying to connect to the iPredator VPN service, but I keep running into problems with LCP. I've tried using knetworkmanager, nm-applet, kvpnc and plain old text-based configuration to no avail. Here's a snippet of pppd's output:

[Code].....

(I've got "defaultroute" in my /etc/ppp/peers/ipred config file.) Any ideas what could be causing this? Could it even be my router? It claims to support PPTP, but considering it claims a lot of other things which aren't true, I wouldn't be surprised if it was the culprit.

Fedora Networking :: DHCP Lease Renewal Failing On Wired Ethernet Connection?

Aug 1, 2010

I'm running an up-to-date Fedora 12 machine with the Gnome desktop (meaning with Network Manager). My network connection is a wired ethernet to a switch which then connects to a Netgear router. For some reason, this machine can't renew its leases with DHCP, so NetworkManager deactivates eth0, taking my machine off the network. I have to click Network Manager and enable eth0, which seems to work every time.

How can I fix it? Here are the relevant bits from /var/log/messages showing a failed DHCP request and then the successful renewal.

Code:
Aug 1 04:00:08 ironton dhclient[12452]: DHCPREQUEST on eth0 to 192.168.1.1 port 67
Aug 1 04:00:08 ironton dhclient[12452]: DHCPNAK from 192.168.1.1
Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): DHCPv4 state changed reboot -> expire
Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): device state change: 8 -> 9 (reason 6)
Aug 1 04:00:08 ironton NetworkManager[1261]: <info> Marking connection 'System eth0' invalid because IP configuration expired.

Networking :: Using Ethernet To Power WiFi Network And Setting Up WiFi?

Aug 23, 2009

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

Networking :: Network Service Failing To Start

Mar 5, 2011

I have recently installed CentOS onto an old machine to get it up and running as a basic web/mail server. Originally the Network Interface worked ok, however I have been editing /etc/sysconfig/network-scripts/ifcfg-eth0 to try and set the IP address to be static.Now when I run the 'service network restart' command it won't bring the eth0 interface up and comes up with the following errors;

ifcfg-eth0 Line 3 DEVICE: command not found
missing config file ifcfg-ifcfg-eth0

It doesn't seem to like any of the command words, even though most of these were in the original file that worked and the ones I added to do static I have commented out.

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.

Ubuntu Networking :: 9.10 - WiFi Connection Not Working

Feb 3, 2010

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.

Ubuntu Networking :: Connection Refused Through Wifi?

Jul 23, 2010

I cant connect with ssh to my workstation using my notebooks wireless lan. with cable I'm able to connect.so the funny thing is, if I first establish a connection from my workstation to my notebook (like ssh it or just ping the notebook) I'm able to create a ssh connection from my laptop to the workstation using wireless lan.scanning my workstation from the wireless lan of my notebook with

Code:
nmap -sT -p 22 ventury
says port 22 is closed

scanning it from the notebook with cable lan,it says port 22 is opened

scanning it from the wireless lan of my notebook an have sent a ping from the workstation before says port 22 is opened.ution.

I got a 64bit version of Kubuntu 10.04, up to date, installed on both, my workstation(ventury) and my notebook (defiant).the question is: Do I always have to ping my notebook first if I want to ssh from it to my workstation or is there some other solution? And why does it work fine with cable, but not with WiFi?

Ubuntu Networking :: 2wire WiFi Connection In 10.04?

Jan 9, 2011

I'm brand new to Ubuntu, and Linux in general, and honestly don't know what I am doing. I installed Ubuntu 10.04 on my external hard drive and am able to boot fine (other than an issue with my monitor falling asleep because my graphics card needs a different driver. I have a work around for this that i'm currently using but I would like to fix it permanently and thus need an internet connection.)

When trying to connect to the network in my home, I am unable to. I click on the WiFi symbol in the top right corner, and I can see my network. I then click it and a page comes up asking for the key. I put it in but it doesn't sync and usually after a minute or so it pops back up asking for the key again.What can I do to gain internet access? I'm unable to connect my computer via a hard wire Ethernet cord and need to sort out this WiFi issue.

Ubuntu Networking :: MacBook Pro 7,1 Wifi Connection?

Mar 14, 2011

I bought my MacBook Pro at the beginning of the school year when I went to college. I am now living in a dorm where I do not have access to wired internet connection, so I cannot just plug my computer in to download stuff. If need be I can of course borrow someone else's computer to download something and then just transfer it over with a flash drive.

Anyway, I have a virtually new MacBook Pro that I bought in August. Using refit I have dual-booted OS X and Ubuntu (obviously I am posting this from within OS X) but I cannot manage to get connected wirelessly to the internet. I have tried this many many times with many many distros and have never once been able to connect. I understand that there are various tutorials around but none of them seem to help me at all and I really want this to work. I've been looking around and trying things for about two days now. Can someone give me step by step instructions (or point me toward some simple ones) starting, if need be, from a fresh install as to how to get wifi working on my macbook pro? I am also completely willing to switch versions of Ubuntu if that would help.

Ubuntu 10.10
Hardware-
MacBook Pro 7,1
Intel Core 2 Duo
Card Type: AirPort Extreme (0x14E4, 0x8D)
Firmware Version: Broadcom BCM43xx 1.0 5.100.198.11 )

Ubuntu Networking :: Way To Ban A Wifi Network In Network Manager
