Ubuntu Networking :: USB Modem Not Detecting

Jan 30, 2011

I have a USB modem working in windows. But no luck to connect using Ubuntu 10.04.

I have setup usb-modeswitch and other stuff. The modem is attached to port ttyUSB0. But when i run "sudo wvdialconf" it displays message like this.

Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Modem Port Scan<*1>: S0 S1 S2 S3
WvModem<*1>: Cannot get information for serial port.
ttyUSB0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyUSB0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 9600 baud
ttyUSB0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.

Sorry, no modem was detected! Is it in use by another program? Did you configure it properly with setserial?

Ubuntu :: USB Modem Not Detecting?

Dec 4, 2009

In my laptop, ealier in XP OS whenever I was connecting USB Modem, it was giving message "Power surge on USB Hub Port". Now, I have put new hard disk with a single partition and installed Ubuntu 9.04 on it. After installation, it was detecting USB for a day or two and I/net was working fine. But now the system is not detecting USB Modem et al. Is it because of some hardware problem or is there anything that I can check into Ubuntu?

Ubuntu Networking :: Install Modem Driver For The Alcatel X200 USB Modem?

find and install modem driver for the Alcatel X200 USB modem?

I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.

Ubuntu Networking :: Not Detecting Network With 9.04

Mar 11, 2010

I'm trying to get my friend's laptop(acer travelmate 2200) to connect to his wireless network. I just installed a new hard drive and installed a dual boot windows xp/ Ubuntu 9.04 setup.

His laptop still connects fine with the old hard drive with windows XP installed, so I know the hardware is working.

When I click on the network manager , however, I don't see anything. Normally , I'd just hit the network manager and I'd see the available connections , but on this laptop I'm not detecting any.

The only thing I can think of , is that Ubuntu doesn't have the proper drivers needed for the wireless card in the laptop. But I don't know how to go about checking this since whenever I've done this before it's always just worked automatically.

Ubuntu Networking :: 10.04 X64 NOT Detecting As Gbit, Only 10/100 Most Of The Time

May 24, 2010

Code:
~$ sudo mii-tool -v eth0
eth0: negotiated 100baseTx-FD flow-control, link ok
product info: vendor 00:07:32, model 17 rev 2
basic mode: autonegotiation enabled

[Code].....

Sometimes my network will be gbit, others it wont. Its quite annoying when trying to transfer large files to and from my server. Hardware is Asus K7 series laptop, which works "sometimes". Can't really determine when it wants to choose gbit.

If i mii-tool -r (renegotiate) it doesnt get better, and -f (force) doesnt provide the option for 1000baseT, only 10baseT and 100baseT.

Ubuntu Networking :: Not Detecting Any Wireless Networks?

Feb 27, 2011

First time ever switching from windows. Mainly doing this cause I though it would be fun to learn a new OS and see how it is.From watching a few videos it looked like all I have to do is click on the wifi logo at the top of the screen and I would get my router and a bunch of others (does this on windows) but when I click on it I dont get anything. I think it might be that im running this on a laptop. My wifi card is: Standard Dell Wireless 1501 802.11 g/nIts a new dell inspiron 5000 laptop i customized a little with more ram and a new video card.

Im guessing I will need to provide more info but as I said at the start Im new to this and not sure how or what info I would need to provide. Please just tell me how I can get any data you need and il get right on it. (I used Wubi to install this, went off without a hitch)

Ubuntu Networking :: Winbond USB WiFi W89C35 Not Detecting Other Computer

May 1, 2010

I've got two computers, with one (my current one I'm posting with) acting as a bridge for the other to access the internet (ICS, yay). Under windows there's no problems, everything goes smoothly on boot up. However I got a copy of Ubuntu 9.10 via mail a little while ago and got around to installing it today with the intention of updating it to 10 while I'm sitting here programming. Thus far, I haven't had any luck getting the networking to happen. As far as I can tell,

Here's what's going on:

Ubuntu sees the USB dongle Lights are flashing on it, it's got power and being interacted with Ubuntu's Wireless Network dock icon has entries for two nearby WiFi networks (my own with password, and someone else next door, also passworded so I can't try theirs) Ubuntu asks for a key to use with logging in After 20-30 seconds of trying it asks again for a key to log in.

lshw -C Network shows:

Code:

lsusb shows

Code:

Sudo iwlist scanning correctly identifies two access points, however it can't seem to identify what the encryption type is on my computer.

I'm using WEP encryption for my Wii to be able to get online, and the password is set correctly (yay for show key). Looking at this computer's activity monitor I can see the mac address of the USB key.

Disabling password protection on my computer gets Ubuntu to recognize that there is indeed an unlocked network available now, however it fails to connect, once again.

Am I better off just ordering a copy of Ubuntu 10 on CD? Besides sneaker net with a 1 gig tumb drive there's not much I can do to get drivers over.

Ubuntu Networking :: Detecting Idle In Pidgin And Other Apps In VNC Sessions?

Aug 15, 2010

I run pidgin instant messenger via fbpanel taskbar via fluxbox window manager via xvnc vnc server via xrdp remote desktop terminal via sesman session manager.

One problem I've found is that Pidgin does not detect when I stop mousing or typing. I also run gnotime time tracker and it too is not able to detect when I don't type on the keyboard or move the mouse in my X-Windows.

Some questions:Is there a common problem? Is there a workaround? Is there a way to diagnose the problem?perhaps a program which says which window got the input which resets the idle timeout

Is there a way to examine or record the idle periods?

Ubuntu Networking :: Wired Network Card Not Detecting Lan Cables?

Dec 8, 2010

I have a 64 bit install of Ubuntu 10.04, I was surfing up to 11:30pm EST last night, shut down for the night, upon reboot am unable to connect to the internet or my local network. Ubuntu seems to think that I have no ethernet cables connected.My networking is controlled by my motherboard (Gigabyte P55A-UD4P) and the problem is not on my cable modems side. The modem has multiple wired jacks, all of them are unresponsive with my Ubuntu PC while my roommate can connect to all of them with his Windows 7 PC. Both network cables (the one connecting to his box and the one connecting to mine) are interchangeable: They both work on his and neither on mine, so there is no broken cable.I've followed the troubleshooting in other posts, here are some commonly requested diagnostics:

ifconfig -a
Code:
eth0 Link encap:Ethernet HWaddr 6c:f0:49:53:1f:c0

The lan card light is on on the VectorLinux machine.

typed commands like ifconfig -a, lsmod, lspci got the reading:

Ubuntu Networking :: Not Detecting Wireless Networks On Dell Inspiron Mini 10?

Jul 6, 2010

I recently installed Ubuntu Netbook Remix on my Dell Inspiron Mini 10, and for some reason it isn't detecting any wireless networks. The wireless works perfectly fine when I boot to Windows XP on the netbook, but not when I'm using Ubuntu. I tried troubleshooting using this htmlAt the "check for device recognition" step, the terminal tells me that it's disabled, but as far as I can tell there isn't a physical switch that allows me to turn the wireless on or off, and again, it works perfectly fine when I use XP. What should I do?

Networking :: Detecting And Logging Lost Internet Connection?

Dec 8, 2010

We have an Asterisk machine that we suspect periodically loses internet connectivity, causing all calls to drop. First, would this sort of thing be logged anywhere out of the box? I haven't noticed anything in /var/log, but that doesn't mean it's not there. If this is not typically logged, how I might go about logging it? I'm currently running a bash script from cron every 5 or 10 minutes which pings Google and writes success or failure messages to a log file. This works fine for extended outages, but if the internet connection drops and comes back between cron runs, it won't be caught.

Ubuntu Networking :: Can't Install Card Driver / "Detecting Your Network Controller?

Feb 13, 2010

I recently installed Ubuntu 9.10 on an old family laptop. It is a Compaq Presario V2000. Everything works perfectly except no wireless networks are recognized, even though I know there are available networks. My network controller is detected but is not doing it's job, which is finding available wireless networks! Using "system testing" I found this out about my network controller:

Fedora Networking :: FC11 Not Auto Detecting Ethernet Interface

On FC10, when system boots up, it would auto detect (from DHCP) and configure eth0.

This does not happen on FC11, but I can manually configure the interface. The entries in /etc/sysconfig/network-scripts/ifcfg-eth0 are identical on both OS releases.

Don't know if this is related, but when I run System->Administration->Bootloader, it fails system-config-boot - missing module kudzu.

Networking :: Detecting Broken Connection Before Sending Data With Sockets?

Oct 28, 2010

I am writing a code in Python where a socket client changes data with the server. That works nice if the connection is up. However it is also supposed to work offline. So I need to be able to detect if the connection is up before sending data, but I was not able to do so. A summary of the code is like that:

Code:
try:
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect( (self.host, self.port) )
connected = True
except:
connected = False

if connected:
data = "some data byte"
try:
socket.send(data)
except:
connected=False
socket.close()

If I unplug the cable after the connection is ready then the socket sends data and does not detect the connection failure. What is amazing is that the client detects the connection failure just after the cable has been plugged again. Of course there is a loop in the code above and always that connected==False a new connection is made. How could the program detect the connection failure before sending data and then lead the code to an exception?

Ubuntu Networking :: Cable Modem Networking - Can't Connect To Each Other On The Home Network

Feb 14, 2010

I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
