Ubuntu Networking :: SSH Session Freezes After Connecting Over Wifi?
Oct 16, 2010
I am connecting from my WinXP laptop to my Ubuntu Server desktop using PUTTY. The laptop is using Wifi and the desktop is on a wire. I have a D-Link DI-524 wireless router. My session works fine for a while, and then freezes, sometimes after only a few seconds, and sometimes after many minutes. The same thing happens when I use VMWare Server Console to connect from the laptop to the desktop's virtual machines. Other connections between these machines under this setup (RDP, samba, SVN) do not experience problems. I usually do not experience problems establishing the SSH and VMWare connections.I have ended up using Windows Remote Desktop to connect to a Windows XP virtual machine on the desktop, and opening a PUTTY session on that machine. That's a nice workaround, but it makes it so that I have to have that VM running in order to have a reliable SSH session to the box

I've happened across a wireless router that has a gateway address of 192.168.0.1 and allots IPs from 192.168.0.64-255. My laptop wouldn't connect to it automatically, so I was playing around and found that it needed 0.x instead of 1.x. I thought the network manager on ubuntu would have figured that out?! Now its a separate story that the router happens to have no admin password

I am working with ubuntu (gnome) 10.10 maverick 64 bit on a HP pavilion 2713ca. I have installed the Broadcom sta driver for a BCM4328 wifi driver. After setting wpa security with my password, the wifi network worked for many weeks. However, in the last few days it does not connect no more. I have tried to reinstall SSID. And I have checked to see if eth1 was still there:
root@max-HP-Pavilion-dv2700-Notebook-PC:/home/max# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

I'm using a HP mini netbook, and I recently installed Ubuntu on it. I updated and did the whole proprietary drivers activation and it now scans and sees networks but I am having trouble actually using them now. It says that it is connected to a wireless network but it never loads any pages.

im using minimal ubuntu 10.04 and im having trouble connecting to wifi using the terminal. the wifi worked perfectly on the desktop version. i followed this guide [URL] and looks like then i used '/etc/init.d/networking restart' and get this now it seems ive disabled wlan0 as $ sudo lshw -C shows
i tried to enable it again by using 'sudo ifup wlan0' but i get a few errors i think the 2nd errors may be because i tried to download another driver for the wireless using 'wget [URL] and then 'dpkg -i rt3090-dkms_2.3.1.3-0ubuntu0~ppa1_all.deb'

Yesterday, I did a clean install of Lucid on a T42 thinkpad, with wireless card as identified by lshw below. I did the installation from within a live CD session, with wifi enabled.
Code:
description: Wireless interface
product: PRO/Wireless LAN 2100 3B Mini PCI Adapter
vendor: Intel Corporation
On reboot into the fresh system and update I had the issues that others have seen with network manager not connecting, repeatedly asking for password and so on. Oddly enough, using a Netgear usb wifi dongle worked perfectly, so I thought there might be a driver issue. Updates did not help. The network manager icon would not appear in the notification area at all when attempting to connect to wifi in a cafe locally. Today, I did a fresh re-install from the same CD with the home wifi switched off and no internet connection on the laptop. No issues. Wifi is working perfectly at present. I had to make the home connection available to all users to stop the keyring password request (I use autologin). I'll be trying to connect at local cafes tomorrow (one has no security, one uses an ascii wep password, and a third has a WPA encryption)
Is it possible that the settings from the live session are carried over in some way and interfering with network manager in some way? (This all started because my minimal install (see signature) reached a state where it would not show the network manager icon when attempting to connect to wifis in cafes and colleges, which I need to do. I decided to reinstall to return to a known state. I may try a minimal installation and manual wifi connection from the command line next...)

I am a newbie trying to setup wifi using 9.10 on a compaq nx9010 . The driver is activated for the broadcom 4320 rev 2 chipset. the wifi light is on.I can connect to my neighbors's unsecured network, but not mine which is using personal WPA2 security.
I am using a lynksys Wireless-N Broadband Router WRT160Nv2 I have installed WICD and removed the gnome network manager WICD tries to validate authentication which fails. then it tries to obtain an ip address which fails. finally it says: CONNECTION FAILED: UNABLE TO GET IP ADDRESS". meanwhile it is showing the wireless network at 100% signal.
last nite tried changing wifi channel, changing to WEP, installed and tried WPASUPPLICANT and WPA_GUI. Unfortunately , nothing worked. The wifi controller was able to assosciate with the network but could not authenticate. I'm wondering if the passphrase that I type in on the computer is somehow being turned into a hexidecimal or something so that it does not match what the router has as the pass phrase.

Running 9.10 Ubuntu on my laptop. It connects fine to regular access poitns, but for some reason it won't connect to my android wifi adhoc sharing. I have it as dual boot with Windows and windows connects to it perfectly. From Ubuntu 9.10 it tries to connect... then just disconnects. Would be killer to be able to use it with my adhoc wifi sharing! I prefer my Ubuntu boot, rather than my windows one

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'm a novice using Ubuntu 10.1 on an Asus EeePC. For several days, my computer has refused to connect to the office wifi, though it's had no trouble doing this in the past. It recognizes the signal, and the wifi icon keeps indicating that it's in the process of connecting, but the process never completes. Every few minutes I'll be asked to re-enter the password. Eventually it gives up.
I'm not sure if this problem extends to other wifi networks or just the one at my office.

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.

I often connects my laptop (Asus EEE) to my HTC desire hd with the wifi hotspot. But this doesn't work since yesterday when I upgraded to 11.04. When I connect the laptop to the phone the screen on the laptop goes black with a lot of scrolling text then it freezes.
This worked out of the box without any problems with 10.10.

moved to Fedora 11 but can't figure out how to get my wireless working. I have the broadcom driver installed and the Network Manager Applet shows the available wireless networks, but when I click on them they just don't connect.I get the following output on lspci regarding the wireless adapter:03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)

I was running 9.10 in LiveCD mode and was unable to get online. Went to System>Administration>Hardware Drives and found "Broadcom STA wireless driver". Cool. So I went ahead and installed 9.10 (dual boot with Vista), repeated above steps but found no "Broadcom STA wireless driver" option, in fact no proprietary drivers. So I still cannot connect to the Internet, and I don't know where to go from here. (Note: I installed 9.10 side by side with Vista: good? bad?)

I've been working on this since last night (a few hours) but can't seem to find what I am looking for. I'll spare you the details of what I've tried already.
Could someone guide me through connecting to my Ubuntu server using a remote X session? The "kicker" is that I want to do this from a Knoppix LIVE CD. So whatever method I am given will have to be something that is common to most Linux distros.
I imagine I will need help with two important steps:
1) verifying that I have an xserver of some kind running on my server.
2) command line statement for starting the Xserver from the remote machine.

I have been updating my system and making a few changes and now I have a serious problem with GNOME (as far a I understand). In the Desktop if I try to start some applications such as the text editor gedit it crashes and won't start. Some applictions start from the menu some don't (e.g. services) and others start and then crash if I try to example manipulate them (e.g. open a file in openoffice).
In the case of gedit if I try to run it from the command line as root I get the following
# gedit
(gedit:6475): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.Illegal instruction [code]....
When I try to start the services (i.e. /usr/bin/system-config-services) I get:
Mar 20 00:35:54 ##### kernel: system-config-s[6536] trap invalid opcode rip:3e18ffd008 rsp:7fffeeffdb30 error:0

After logging into fedora about 5 minutes into the session everything except the mouse freezes on the screen. There is nothing that works. A hard reboot is done and the same thing happens after logging in. The system use to work fine up until a few weeks ago. I suspect it may be an yum update.

I am having a bit of a problem connecting to a dynamic WEP WiFi network.
Code:
Apr 15 11:39:31 MyComputer NetworkManager[943]: <info> Activation (wlan0/wireless): access point 'MyUniversityWifiSSID' has security, but secrets are required.
Apr 15 11:39:31 MyComputer wpa_supplicant[1002]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
[Code]....
I have googeled that specific error about the WEP line, and it *was* a bug at one time, but according to the bug tracker, it has been fixed. Not so, me thinks.
So, does the specific error above look familiar and does anybody know of a way to fix it?

My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

Just upgraded to Natty on both my desktop and netbook. Desktop upgrade was a breeze, and I'm liking the changes.Netbook isn't having such a good time however.First login after upgrade (using default gnome settings) played the login sound and froze. No mouse movement/keyboard response. I tried again with Ubuntu Classic - nothing. Finally Ubuntu Classic No Effects did correctly boot/login. I allowed it to perform a proper shutdown (was doing a power flip beforehand), and it was able to boot into normal Ubuntu Unity.
I enabled the wifi module using the laptop's keyboard shortcut, and Ubuntu searched for nearby networks. After finding my prefered network, it started to connect and threw the system into a command console abyss and froze. Tried again on the Ubuntu Class no effects, and it freezes on connecting to a wifi network. If the laptop crashes and I have to perform a power cycle, I can't boot into normal Ubuntu mode. I have to go back into Classic no effects.

I have seen tons of threads on the internet about Ubuntu 10.04 having wireless issues but none of them have lead to me fixing the problem so I decided to come here. I have been able to connect to access points before but sometimes I have to reboot or reboot twice just to be able to see the wireless points and the enable wireless is always greyed out. And if I am connected to an AP or hardwire the connection drops frequently.

just installed Debian 8.2 on my ThinkPad X230 laptop using netinst. I installed only basic system and then install packages I need manually. Now I stuck with NetworkManager and Wi-Fi. NetworkManager and its applet (package network-manager-gnome) installed, I can connect to my Wi-Fi network, but after reboot a dialog asking for passphrase for keys appeared and even after entering correct passphrase NetworkManager does not connect to the Wi-Fi, so I need to connect it manually.

I have a Skytex SX-E700 netbook with a Linux system and I cannot connect to my Time Warner home wireless system. It will connect but the IP address is invalid. Time Warner has no idea how to fix it. Has anyone had this problem and figured out how to fix it? By the way -- I can't find any system info on this little netbook and can't seen to get into anything that tells me what it contains.
