I have been useing Ubuntu for 1-2years now. Lately I've been having some troubles with my wireless Internet connection, almost every 1min i disconnect and connect again few sec after and thats like hell if you try to fx. update. I have 85-92% signal so thats not my problem.I use Ubuntu 10.04 and the standard network manager. I'm connected to a netgear router and my computer is a acer aspire one.

I have a cisco linksys wireless adapter (WUSB600n) which, most of the time, great when booting up. But mostly after some time (1min- 1hr.) it disconnects. When checking the status I can see some of the networks around me, including mine. But selecting it doesn't do anything. I searched the forums and tried:
sudo dhclient
and
sudo /etc/init.d/networking restart
But still no connection; the only thing that helps is rebooting.
do not post such long blocks of messages directly on the forums. Attach the output as .txt or use a pasetebin.

All is great except i started to notice my Wireless Network get disconnected and then reconnects every 5 minutes or so. Also the NetworkManager Applet 0.8 keep annoying me with the notifications that its disconnected and then reconnected.
I do not have this issue while using Windows 7 (in the same area). Can this be fixed. As i really want to move my day to day computing need to Ubuntu.
Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.
I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.
why my wifi connection always dc.. i'm using acer aspire 5583, ubuntu 10.04 LTS..

View 1 Replies View RelatedMy network is barely functional. I'm running 2 linux servers connected by openvpn (tun) through routers on both sides. There are Windows clients (98 and XP) on both subnets. One server (ls3) acting as PDC for the domain. The Windows clients use the respective linux boxes as gateways. On the server side (ls3 which is both openvpn server and samba server), all the clients can read/write properly to shares on both sides. The problems are all on the client side. Share connections to the server side disconnect after a few moments.
Browsing on the client side windows machines is fine. I can see shares on the server side. Some server side files open and are readable, writable, other server side files will not open. Some samba logon scripts on the server side can be opened from the client side. Others open after a long wait to a blank file! Permissions on server side files are set to 777 for testing. If a file won't open or reads "blank", that doesn't change no matter how many times you try. A non-readable/writable file overwritten by a readable/writable one can be read and written to!
I can ping successfully from any client on either side to any other client by either ip address or workstation name. Firewalls on both side are set to forward tcp and udp traffic going to port 1194 to the respective gateway linux boxes. Iptables on both linux gateways are down for testing. I tried reversing the openvpn server/client roles with the same result; the same physical side of the network had the problem. On one of the windows 98 clients, I wiped out the networking configuration completely and rebuilt it from scratch. Same result.
One one of the windows xp clients, I tried to rejoin the domain. It went through successfully but the result was the same as above. The network was operating smoothly for several years until the client side dsl modem broke last week. It was replaced with a newer model and at the same time I migrated from a pptp connection to openvpn. How to resolve this, Is this something to do with openvpn? Is this a network hardware problem? Am I missing something in the port forwarding on the routers? My smb.conf files are ancient except I added interface tun0. I have never seen 2 files sitting next to each other in the same directory where one opens and the other doesn't!
I'm running Mandrake 9.2 on the client side and Mandriva 2008 on the server side. I have a Sonicwall firewall on the server side, a Westell 7500 on the client side. I note that during the modem install, the http port was opened to the linux box on the client side and the access log got huge over the weekend and I ran out of disk space until I closed it down and deleted the log. I tried a simple test while viewing /var/log/daemons/errors on the client side. From a windows workstation in the client subnet, I opened a dos window and tried to print a file located on the samba server on the openvpn server machine which I knew NOT to be problematic.
The file printed and there were no errors reported in the log. I repeated the test with a known problematic file. The file would not print. The errors log noted:
Authenticate/Decrypt packet error: packet HMAC authentication failed
I regenerated the static.key file on the server side and scp'd it to the client side and restarted both openvpn's. I checked for duplicate files named static.key on both sides. Same error.
just installed this yesterday-there is no disconnect button for the wireless-the only way to disconnect is to disable the wireless altogether.Any else have this problem?
View 9 Replies View RelatedToday I updated a bunch of packages, rebooted. I run lucid 10.04 x86_64, originally Xubuntu but now gnome since I cannot make xfce4-panel tasklist behave with compiz. Anyway, by the end of the day my clock was 10min off. If I use ntpdate at about 10min intervals I see things like:
$ sudo ntpdate time.xxx.xxx.de 1 Jun 18:37:02 ntpdate[9734]: step time server xxx.xxx.xxx.xxx offset 10.043055 sec
I have deleted /etc/adjtime and touch'd a blank file to no avail.
Is this problem serious? Is it likely software or hardware? Is running an ntp daemon the right solution or would it be masking a new software or hardware problem that appeared today?
I'm thrilled using wicd to connect to wireless networks. But when I suspend my laptop using the special keys, I just want to disconnect from wireless without having to use any kind of GUI or curses user interface. It says in the documentation that wicd works by sending DBUS messages, so presumably it's possible to write a command that talks to the daemon directly.But I can't figure out how.Does anybody know by means of what shell command I can tell the wicd daemon to disconnect me from my wireless network?

View 3 Replies View RelatedA friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.

Ive recently switched over to AT&T Uverse TV/Internet service and I've noticed that when I ssh into my linux( 2.6.18-194.3.1.el5xen CentOS) server I get disconnected. When I'm using putty it gives the "network error software caused connection abort" error. When I'm at work using one of our jump servers and ssh'ing from the command line it will freeze up from time to time but never disconnects. I think the problem is either with the OS or the new AT&T modem. At first I had my CentOS server using DHCP and it would disconnect within a few minutes after I ssh'ed. I switched over to a static IP and now it goes about 10 minutes before it disconnects. It doesnt matter if I'm actively typing or not, so it's not an inactivity issue. I have the firewall turned off on my laptop, and since the issue happens on multiple devices, including my iphone I dont think thats the issue.
I have iptables and selinux turned off/disabled so thats not it. In putty I have enabled Keep Alive(30 seconds) and it still disconnects. I opened the port on the modem to allow ssh for the IP of the linux server. Ive also recently reinstalled this server with CentOS so I can't compare with the previous internet provider as I didn't reinstall until after I switched over. BUT previous installs with CentOS 5.2 worked fine with the previous ISP. AT&T Modem is a 2wire 3800HGV-B

I have also tried sudo dhclient but it hasn't helped and I am still unable to connect to the internet
Each time I start up debian -lenny, the network-manager does not automatically connect me to my wireless network. The connection list shows a lot of networks available, but mine is always absent from the list. This means I each time have to go to "Connect to other Wireless Network" in and write in my network name (SSID) and password (PWA2 Personal). Then is connects nicely and everything works fine until next time I boot

I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.

The OS does not even detect that the hardware is present. I have disabled wireless hotkey in BIOS. The only way to make the wireless card "active" is to reboot with the wiredconnection to the router. After doing that the wireless card "wakes up" and works awesome.Is there anything I can do to make sure the driver load at boot?mes I get the error that NDISWrapper is not modprobbed when I go to network configuration and if I wish to do i now? I don't know if that has anything to do with the boot sequence. Using the <modprobe ndiswrapper> command as root does nothing permanant

View 2 Replies View RelatedI recently bought a D-Link DIR-655 router capable of 802.11n operation, upgrading from a DIR-624 router only capable of 802.11g operation. While my overall setup uses wired connections, other people in the house prefer wireless, and the upgrade was undertaken more for a hoped for increase in wireless range, rather than the possibility of increased speed, since the router is located to accommodate the wired connections. However, to test the 802.11n operation I bought a D-Link DWA-130 USB dongle for my now 5-year old laptop, which comes with an otherwise satisfactory 100Mbs ethernet port(eth1) and an 802.11g wireless card(eth0). By checking the dmesg | grep firmware output after I plugged in the dongle I determined that the necessary firmware was rtl8192sfw.bin, which I found on the web, and downloaded into the directory /lib/RTL8192SU.
A subsequent reboot and then YaST > Network Devices > Network Settings showed the device as wlan0, but not configured. I changed the Network Setup Method to ifup (since I can see no way to do a device configuration in Network Manager), and configured the device, and at the same time deleted the configuration for the existing 802.11g wireless card(eth0). I then rebooted, went back into YaST to confirm the wlan0 device was configured and the 802.11g device (eth0) was not, changed the Network Setup Method back to Network Manager, rebooted again. Making sure that the router was set to only transmit/receive using 802.11n I then typed iwlist scan. To my surprise, the output showed first that the supposedly unconfigured eth0 device seemed to be still active, for it found my home network, and claimed that the protocol used was 802.11g. On the other hand, the newly configured wlan0 device produced the message: "Interface doesn't support scanning: Network is down".
First, should I expect iwlist scan to work for a device that shows as unconfigured? And even if it should work, shouldn't it show 802.11n as the protocol, assuming that the router is in fact telling the truth? Is there any independent means to determine if the router is only using 802.11n as it claims? Second, the overall goal is to make the wireless network in the house 802,11n only, and since the dongle is backward compatible with 802.11g, I would expect to permanently unconfigure the eth0 device and use the dongle, both here and on the road.

I just started using OpenSUSE on an old laptop. It seems that I have my graphical problems at least temporarily solved, but I continued to lose my wireless connection after an hour of use. This is an old and well supported chipset (RT2500) and I had never had any issues with it before. I use WPA security, and one kind poster suggested I had a line for using the old "wext" driver in the /etc/sysconfig/ifcfg-wlan0 file, and that seems to have sorted it since I have not had any further issues since doing that edit. I eventually found the information on my own:
# Note: This option requires a wpa driver supporting it, like
# the 'nl80211' driver used by default since openSUSE 11.3.

There seem to be a number of people that believe the junk that NetworkManager is buggy.As I believe the opposite, I want to offer more detailed instructions on how to create the initial connection, and how to troubleshoot the process. Once readers of this group have commented on this draft, I plan to ask the moderators to make it a sticky.
This description will be specific to the KDE desktop. The steps will be similar for Gnome, but the details may be different.
Step 1: Do you have a Network Manager applet in the system tray? If not, use YaST =>
Network Devices => Network Settings. Under the "Global Options" tab, click on the "User Controlled with Network Manager" button. If it is already set, you will get a warning box when "Network Settings" starts.
Step 2: Now you should see the NM applet. Click on it and check the popup. If the "Enable Wireless" checkbox is inactive (gray), there are several possibilities: (1) Your wireless device driver is not loaded, (2) the necessary firmware is not available, or (3) an rfkill switch/button is wrong. For (1), check "hwinfo --network" and check the "Driver" line. If it is blank, then you need to run the command "/sbin/lspci -nn" if the device is connected to a PCI bus, or "lsusb" if a USB device. Post the results on the Wireless forum. For (2), look at the output of "dmesg | grep firmware", which will list the name of the file(s) to be loaded.
For Broadcom devices that use either b43 or b43legacy, the firmware is obtained by using the command "/usr/sbin/install_b43xx_firmware". You will need a wired connection to complete this step. For (3), you will also need a wired connection and install the
"rfkill" package using the command "sudo zypper in rfkill". The interrogate the current settings with "/usr/sbin/rfkill list". If any device is "Hard blocked", then wireless will be disabled.
Step 3: Once the "Enable Wireless" checkbox is active, check it and click on "Manage
Connections". Choose the Wireless tab and click on Add. Enter the name for this connection. You will probably want to check the "Connect Automatically" box. Next click on the Scan button. If you do not see your Access Point (AP) in the map, you will not be able to get a connection. Click on the AP you want, and click OK. The (E)SSID should be in the SSID box. The other boxes on this screen should be OK as is. If you have several APs with the same SSID, but you wish to restrict the connection to only one of them, then you should enter its MAC address in the BSSID box.
This usage is rare. Next click on the "Wireless Security" tab and enter any encryption secrets. The correct type should have been selected. For WEP encryption, you will need to use the hex key, not a passphrase. Once this is complete, click OK to close this screen, and the configure screen. During this process, a popup should appear offering to use a
wallet to store the connection secret. If you use a password on this wallet, you will need to enter that password each time you log in. If you set no password on the wallet, the security level is lowered, but entering a password is avoided.
Step 4: At this point, you will need to disconnect the wire. Whenever the computer can make a hard-wired connection, it will supersede any wireless option. The wireless connection should then occur automatically.
I set up 11.4 in my laptopnd, after updating and downloading the proper firmwareeverytihing runs great. I already configured the wireless network via the standard NetworkManager but the connection never starts automatically. When I boot up it reports all the wireless connections available and also let me connect to hidden networks (mine is not broadcasting so I have to use this option). I had to reconfigure my network options the first time I selected Hidden Networks but it connects fine. Please note I had already selected the "Automatic connection" optionSo the only question is how I configure my equipment so it connects automatically to the already configured network
