Ubuntu Networking :: Connecting To Wifi With 192.168.0.x Addresses

Mar 29, 2010

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

Ubuntu Networking :: 10.10 - WiFi Not Connecting Anymore

Dec 13, 2010

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:

Ubuntu Networking :: Connecting To Wifi Using Terminal

May 3, 2011

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'

Ubuntu Networking :: Connecting To Neighbors Wifi But Not Mine?

Jan 8, 2010

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.

Ubuntu Networking :: LAPTOP Built-in Wifi Not Connecting To Ad-hoc?

May 27, 2010

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

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

Ubuntu Networking :: Connecting And Staying Connected To Wifi

Jan 27, 2011

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.

Ubuntu Networking :: Wifi Won't Finish Connecting - Keeps Asking For Password

Jun 5, 2011

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.

Ubuntu Networking :: Not Connecting Ubuntu 9.10; Broadcom 4322AG 802.11a/b/g/draft-n WiFi Adapter?

Jan 13, 2010

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?)

Ubuntu Networking :: 10.10 Upgrade - WiFi Not Getting Connected By Default

Oct 13, 2010

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:

Ubuntu Networking :: WIFI Performance Degraded After Upgrade To 10.10

Jan 12, 2011

I would like to re-raise this topic that I have seen on other discussion boards but seems to be going no where.I have been using Ubuntu for many years now having switched from other distributions. All my machines ran some version of Ubuntu, until just recently. I upgraded my personal HP TX2500 from 9.04 to 10.04. No problems. After 10.10 had been out for a while I upgraded again. The wireless would drop when busy/(signal slightly weakened) etc. It would not function again unless the wifi module was reloaded.

Then I installed 10.10 on my HP NC6400 the same thing occured. I installed Ubuntu 10.04 instead. It seemed no better. After some Googling, it seemed I was not alone. I tried all the suggestions I could find and none of them worked. One suggestion was to install Fedora 14. This works perfectly on the nc6400. The HP TX2500 has been reinstalled back with 10.04 where the wireless seems ok and I assume I am stuck there for a while.

Now my question is why would the networking behave this way for Ubuntu 10.10 (10.04 as well on the NC6400) but wireless on Fedora 14 is perfect (I mean really good! Better than either Ubuntu 10.04 or 10.10 on any of my laptops) on the NC6400. I am hoping that we can find a way to fix this, otherwise I will likely have to drop Ubuntu completely because I do not have an upgrade path for laptops. There must be many other users in the same position who are not discussing it and just rebooting each time this occurs. This must give a negative perception of otherwise great software.

HP TX2500

Ubuntu Networking :: Wifi Hotkey Not Working After Upgrade To 11.04?

May 27, 2011

after upgrading to 11.04, I can't use the fn-f2 combination anymore to activate the wifi card. I'm using a Dell latitude laptop. Wifi is functioning normally when it's on and I can even turn it off with the hotkeys. When I try to turn it back on, the light goes on for a second and than dims again. I than have to reboot into Windows to get it back on, which is kind of annoying.

Fedora Networking :: No Wifi After Upgrade To F14?

Dec 21, 2010

i've got an IBM thinkpad 1858. fedora 11 & 12 (KDE spin) were always running without any major problems. today, i upgraded the system from f12 to f14 using preupgrade (and a wired internet connection). the upgrade process went smoothly.

but now i don't have a wifi connection anymore - there is no icon shown in the system tray and the led does not blink. the network configuration tool shows eth1 to be inactive and the button to activate it is grey.

Ubuntu Networking :: Dell Inspiron 6400: No Wifi After Upgrade?

May 9, 2011

I'm on a Dell Inspiron 6400 which had been running Ubuntu 10.10 (32 bit) perfectly.Today I upgraded it to Natty and the wifi now refuses to work. Details: While no Additional Drivers were needed on 10.10, upon installing Natty it prompted me to install "Broadcom STA proprietary wireless driver". Now when it's active I don't even have the option 'Enable Wireless' (only Enable Networking). If I disable STA the Enable Wireless option comes back, yet I can't actually search for wifi networks or connect to my saved one. The keyboard key to enable/disable wireless also does nothing.

I can take this laptop to somewhere with an ethernet connection for an afternoon if need be, but am currently stumped as to what to do. Obviously I know this machine can handle Wifi under Ubuntu - it's definitely a Natty problem.

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

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.
