I just got a new T400 and installed Ubuntu. Everything is fine and I'm really impressed by this OS. But seems my wireless network is very unstable. Sometimes it just can't connect.
The wireless interface is:

product: PRO/Wireless 5100 AGN [Shiloh] Network Connection
vendor: Intel Corporation
I am having trouble with my laptop's wireless. It doesnt work after a normal shut down. The version is 9.10 and my computer is lenovo T400.
Below are some outputs of commonds.
Code:
op@power:~$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

Suspend works about 50% of the time on my T400. The other 50% of the time, the screen goes blank (light stays on), there is a blinking cursor in the top left, and the "moon" light blinks forever.
I've got the latest ATI (3470?) video driver installed. I've seen a few posts about this but no clear solution. Anyone here have this problem and (more importantly) been able to fix it?
I'm running Karmic Koala 64 bit on my Lenovo T400 laptop with switchable graphics having both Intel and ATI video cards. I've set my bios to use the intel card only and turned the automatic switching off. So far so good, but I'd like to turn on compiz for basic window animations. When I try to start compiz by selecting
Code:
"Appearance Preferences" -> "Visual Effects" -> "Normal"
I get an error message saying "Desktop effects cannot be enabled"
Code:
"System" -> "Administration" -> "Hardware Drivers"
doesn't show any new drivers that could be installed. This was working out of the box when I first installed Karmic Koala a few month ago, but things got messed up when I installed the restricted drivers for my ATI card. Now I can enable compiz if I switch to ATI from my bios settings and install the drivers but I don't want to use it due to high power consumption and I've removed the ATI drivers.
Here is my xorg.conf file:
Code:
Section "Device"
Identifier "Configured Video Device"

The mic on my laptop (lenovo g555, Ubuntu 11.04) doesn't work. No matter what application I'm using, it won't register. It worked just fine when I had windows installed. I've checked my sound preferences, and my input isn't muted, and no matter what volume I put the input at, it won't pick anything up.
View 9 Replies View Relatedi've installed it on my parents old computer, mostly for downloading. But wired internet did work all the time but then i had to reset our router because of some problems and now it doesn't work anymore! But the strange thing is, if i put the cable on my own laptop with windows on it, then it works as normal.
So i guess its some kind of DNS problem, but i'm very new with ubuntu and also not so good with computers. Our network is simple just an modem connected to an router: Sitecome WL-341.
I installed Ubuntu10.04, It cannot driver Wired network and wireless. Later I installed linuxMint9, wireless is ok, but wired network doesn't work. I am sure the lan cable is ok. It works in Windows.
View 3 Replies View Relatedwhat is the command to restart the network services? ive forgotten i think it uses -hup switch though. about 1 in 20 boots on my desktop ubuntu system results in the system insisting its no longer on a network yet has a fully functioning network card. a reboot always fixes the issue but that doesnt seem like a long term solution to me. If I ping a neighbouring system I get nothing. (sent packet count increases in ifconfig) If I ping from a neighbouring system back to my desktop I get nothing (no change in packet count) I can bring down and back up the network interface with no results. A sniffer shows the system definitely isnt sending anything out Everything worked previous boot and will work again after a reboot.
View 2 Replies View RelatedI recently got a lenovo w510 laptop and I installed openSUSE 11.3 KDE on it. the wireless works fine at home (802.11g WPA2) when I go to work I have tried to set up the wifi for the 802.1X PEAP network but it doesn't look like it even tries to connect.
The work network set up is as follows. non-brodcasting SSID (do I need to tell network manager of this? I manually enter the SSID no problem)
Dynamic WEP 802.1X
PEAP
blank anonymous identity
no CA cert (I suspect this might be the problem)
PEAP v 1
MSCHAPv2
I have verified my username and pw several times, as well as the SSID. Just yesterday I helped a co-worker get on the network under ubuntu and it worked like a charm.
The Hardware profile displays the wifi card as a "WiFi Link 6000 Series" It is an intel card.
I have two simultaneous active mobile connections through my two mobile phones and USB data cables. Yet I can only send/receive with one connection.Each of the phone modems have a node in /dev, namely ttyACM0 and ttyACM0. So the modems are detected correctly.After setting up two dial-up connections with the two modems I have two ip's. Ifconfig-a confirms this:
ppp0 Link encap:Point-to-Point Protocol
inet addr:10.10.219.60 P-t-P:10.6.6.6 Mask:255.255.255.255

I installed Ubuntu on a machine after erasing everything else and the wireless has never worked. It says that the wireless has already shut down even though it recognizes the wireless network and my other non-linux machines see the network and work fine.
View 1 Replies View RelatedMy desktop PC has 2 NICs. I have Ubuntu on it since several years, and I remember that both eth0 and eth1 used to work. However, I discovered recently that currently only eth0 works, and eth1 is dead, but I don't know why. It's been a while since I've tried eth1, so I have no idea when exactly it broke. I suspect the problem may be related to the fact that the MAC address is incorrect: it is set to 00:00:00:00:00:00, which seems wrong. But I have no idea how this happened...Any idea what might be wrong and how I can fix it? Here is some output which I think is useful:

I'm trying to activate a wireless network on an ubuntu server 10.04. The machine has a TPLink PCI wireless card. Card is well recognized, and scanning for wireless connection it finds correctly the essid of the access point in the room. But when I try:
Code:
$ sudo iwconfig wlan0 essid "apoint" key s:my_key_8
this error is returned:
Code:
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.I looked for similar situations over many forums, and I found that it could be the card doesn't support the encryption type (My AP uses WPA with TKIP). However if I use an ubuntu desktop live CD on the same machine, I can connect witouth any problem with NetworkManager 0.8.
I'm new to Fedora and have a problem with the network manager. Everytime I start Fedora, it does not automatically connect to the default WIFI Browsed Google and just found [URL]..
View 1 Replies View RelatedI added a repo from launchpad to install latest Network Manager and then installed it (version 0.8). Then I decided to rollback to Karmic's version (since 0.8 doesn't work) but failed: I removed the repo from sources.list
Then apt-get udpate
Then apt-get clean
Then apt-get install network-manager...
But still 0.8 version is downloaded and installed! How can I restore Karmic's version?
I have an Aspire 7741z running Ubuntu 10.04 I just loaded the 32 bit version today, then did the Update manager (398 updates) Before the update everything worked fine. After the update, no wireless. Password & security is correct, all wireless setup is correct. Aside from my network, I do have access to a local hotel (next door) and I can always get into their unsecured guest network, that doesn't work either.
I believe it is the driver since I have loaded Ubintu 10.10 32 bit with the same reaction. It will connect when I put in the live disk, but not from the hard install. output from lspci

i have searched the forum but can't find the solution for stalling network in the middle of something. i have to restart the computer. i cannot rely ubuntu for 24 hours non-stop small server. the stalling problem occurs when I start pulling/downloading via samba or sftp (smb:// or sftp://) from another computers/device (like wdtv). when i check the lenovo, all internet connecetion is dead. ifconfig shows the ip but it just dead.

For about the past month I have been having a very frustrating problem When I boot the system with the ethernet cable attached it acts as if the cable is unplugged even though the connection light is litWhen I boot the system with the ethernet cable disconnected and wait until it boots all the way to gnome and then plug in the cable everything works fine
View 1 Replies View RelatedI'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.

Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.
I just bought a brand new Lenovo ThinkCentre A70z (All in One). Today I installed Ubuntu 10.4 32bit version, Here are the problems I encountered.1) Ubuntu didn't recognize my Broadcom Wifi Card by default, all though the drivers are there on the DVD, it seems to be blacklisted.my hardware details are :02:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4357] (rev 01)Subsystem: Broadcom Corporation Device [14e4:04da]I managed to activate the drivers.the drivers I am using are :

I have a pppoe adsl connection. When I disconnect and try to reconnect, network-manager keeps asking for my password. I type it again and again with no success. When I reboot, it works again. On ubuntu, I use pppoeconf and it works well. So on Fedora I made a connection with pppoe-setup but neither ifup nor

commands work. When I type
Code:
pppoe-connect

Ifup ppp0 doesn't work either. However, with exactly the same settings, ubuntu connects to the internet.

After the upgrade i have this problem: When i print something it goes right to completed jobs, without an error and without printing. My user is allowed to print, I checked that.
this is from the access log:

When i print the self-test page, it prints fine, so I assume the problem's in the system rather than the printer.
I'm trying to do a clean install of Lucid (10.04.1) 64-bit on a Lenovo X201, Ubuntu only (no dual-boot), using the alternate install disk for an encrypted LVM.
I followed the default options at all points during installation, except that I opted not to configure the network because the computer is not currently connected to a network. The install (said that it) completed correctly.
When I turn on the computer, it correctly runs the BIOS. Then I get a blank screen with a flashing cursor in the upper lefthand corner. The hard drive accesses a couple of times. After a few seconds, the screen goes off (the cursor doesn't just vanish; the screen actually goes off), and it just sits there indefinitely without booting.
I should note that I've tried this with the boot order in the BIOS set several different ways, including HD first and only, with no effect.

A black screen with a lot of text on it and then everything freeze.
I have tried it without installing and it worked (live cd). I have also tried to install it on my desktop machine and it worked fine.
On my laptop, I already have a Windows 7 (64 bit) on another partition.
Did anyone have a similar problem?
I have Ubuntu Lucid Lynx and suddenly my wired internet network doesnt work anymore after a forced restart.
