My problem is that my wireless network traffic sometimes just stop.Like when I tries to update my system, update NetBeans or just download using Uget. I have no clue on what's wrong,Here is my system info:

I have a wireless network using this driver:
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.

View 7 Replies View RelatedI am running SLED 11 and My Networkcard is Intel PRO/Wireless 5300. In short, it is not there anymore! I mean I was connected and everything and the next time I restarted It could not detect any wireless network. I deleted the wireless network card in hopes that the OS will automatically detect it on startup and set it right but NOPE. When I check the hardware information in YAST, it is listed there and it is also working under Windows.
View 4 Replies View RelatedToday I changed my home router's security setting from WPA to WPA2, and my openSUSE 11.4 Tumbleweed system's network stopped working.It is very strange, because it can connect to the wireless no problem and it gets ip address and everything, but I cannot access any websites. I tried to revert the router setting back to WPA, but still the same.Funny thing is I can actually open the router admin page.
Even I plugged the wired lan cable to my laptop, but still the same. It connects, but no internet.Where should I look? My the other laptop with openSUSE 11.4 connects to the same router without any problem.
I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:

I wanted to know if i can install mrtg on a client computer in network and measure the network's router traffic.i know that it can be installed on the server.
View 5 Replies View RelatedI need a simple traffic monitor for Linux, that counts the traffic in a specific wireless network because I have volume restrictions on that one.I tried it using the following iptables rule:
[code]...
iptables -m mac -A INPUT -p all --mac-source <mac-address> ! -s 10.0.0.0/8
where <mac-address> is the router's one. 10.0.0.0/8 is the local subnet. What I actually want is something like --routed-through <mac-address>. Also, is there some way to gather iptables's statistics? Or is there maybe another tool that does what I want (reliable)?
Sometime after I upgraded to ubuntu 9.10 I've been having trouble with my wireless network connection.It will usually log on to the network, then disconnect a shortly after. Then try to connect again, usually successfully, then it cuts off again. Then connects again, then disconnects. FWIW, ubuntu 9.10 works on a different machine pretty consistently, so I don't think its a problem with the router.
View 2 Replies View RelatedI've been running Ubuntu 10.10 (Maverick) x64 quite happily on my Dell e6500 for the past few months until today when I woke the computer up from sleep mode and could not use the wireless. The network-manager applet simply has 'Wireless' greyed out. I tried rebooting, thinking it was an issue with the wireless card not re-powering on properly after sleep, but to no avail. how to begin here?

I am running Ubuntu 9.10 on an HP dc5100MT workstation. Sound works nearly all the time, but once in a while, the sound stops and I have no idea why. The channel is not muted, the volume is 100%, and not even rebooting fixes it. It will just start working on its own.Under the Sound Preferences panel, the output volume is 100%. The channel is not muted. I can get sound out of the internal speaker by changing the connector to "Analog Output (LFE) / No Amplifier", but not out of the "Analog Output / Amplifier" which is the green sound cable plugged into the sound card.I only use this machine as a video player using VLCNothing else.I would like to know some tricks to isolate and troubleshoot this when it happens.

Sometimes instead of this it get stuck on a letter/number (for example, it starts writing "aaaaaaaaaaaaaaaaaaaaa" non stop) and it stays that way until i reboot my computer. Even the leds (num lock, caps lock, scroll lock) stop responding. Yes, i have tried to unplug and plug in the keyboard but nothing really happens.
View 8 Replies View RelatedI am currently using Debian Testing, managing my wireless connection with NetworkManager and the Gnome nm-applet. Both have just been updated: network-manager from 0.8.1-6+squeeze1 to 0.8.2-6 and network-manager-gnome from 0.8.1-2 to 0.8.2-4.On installation of the new packages, I have no problems. However, on a reboot, I can no-longer connect to any wireless connection. I am not prompted on start-up for the password to unlock the Gnome keyring and when I left-click on the nm-applet icon and then click on a network to connect to it, nothing happens.I do not think this is a driver or NetworkManager daemon problem. If I run "nmcli dev wifi" or left-click on the applet icon, NetworkManager seems to scan for wireless networks properly and returns a list including the one I wish to connect to.
View 9 Replies View RelatedI have a wireless cable modem/router and a PCI-E 1x wireless card in my desktop PC. It works perfectly until I connect my Ethernet cable to my local router and printer, no more internet connection. I am guessing there is a setting somewhere that tells the networking software that the hard wire connection is the primary internet gateway. How do I tell it to use the wireless as the primary gateway?
View 4 Replies View RelatedI am running Karmic on a Compaq Presario V3000 and this morning my wireless card is not being detected by Ubuntu's NetworkManager. I have no idea what caused this... literally, it was working when I shutdown my laptop last night. When I right-click the NetworkManager icon in the panel it does not show "Enable Wireless" (only "Enable Networking"). When I run ifconfig in terminal it shows my wireless card as being there (UP Broadcast Multicast). One weird thing - on the front of the laptop there is an LED which lights up blue when the card is working (ie normally), but right now it is orange (ie, if you flick the switch on the front of the laptop to toggle the wifi on or off... I have toggled it back and forth but nothing changes!)

I'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.
Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.
It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.
Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.
I'm using a different computer to post this thread, so I'm manually writing the output.
Code:
sudo iwconfig wlan0
wlan 0 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm

sudo iwlist wlan0 scan

The configurataion defaults for gnome manager have not been installed correctly" so I deleted my music directory and now it boots fine, dont know if that might be part of the issue/ I dual boot win7 and i can get wireless on that partition but not ubuntu
View 9 Replies View RelatedI have been using ubuntu troublefree for some month, but yesterday, suddenly the wireless internet connection stopped working. It happened after i used the turn off wireless network shortcut, now i cant turn it on again (usually this works fine).The situation is now, that when i click on the tray icon showing connection it says, wired network disconnected (it never said this before), then if i click on the wireless shortcut it also says wireless disconnected... But if i click again it doesnt show connections, the disconnected sign just disappears...?
View 7 Replies View RelatedI'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.

View 3 Replies View Related(Ubuntu LTS 10.4) I have multiple mail accounts on Thunderbird (TB). All worked fine with no issues whatsoever. A few months ago it suddenly started giving me this alert message related to my yahoo.fr pop3 account
Quote:
The POP3 mail server (pop.mail.yahoo.fr) does not support UIDL or XTND XLST, which are required to implement the ``Leave on Server'', ``Maximum Message Size'' or ``Fetch Headers Only'' options. To download your mail, turn off these options in the Server Settings for your mail server in the Account Settings window.
Obviously I checked if these settings were somehow changed. They weren't. It should leave messages on the server indeed, but I don't use no max message size or fetch headers only options. The original settings are what they used to be and how they have always worked.
The thing is: everything works normal if I start up TB. It downloads the messages, puts them in the folders where I want them to come etc... The problem seems to appear after a while (mostly a few hours, or overnight). It just stops downloading the messages from my yahoo.fr account. When I click the Get Mail for my yahoo account the above alert message pops up.
There is only one solution really. Close TB and restart it after which all works fine again.
It might be that the problem is related to another issue reported as bug # 689453 in launchpad that started around the same time (a few months ago). That bug forces me to have to end the process through the System Monitor where Thunderbird-bin uses almost 100% of the CPU and doesn't shut down.
Obviously it doesn't avoid me from using TB, but it starts to work on my nerves to have to close down TB (sometimes through the End Process in system monitor) and then restart it so frequently.
I have the standard wired LAN NIC and a wireless NIC installed. What my problem is, the wireless NIC will not take any internet traffic. The LAN connection gets it's internet from my LAPTOP with a Clear 4G module. I have a very strong wireless connection, but when I remove the LAPTOP from the network, I get nothing on my Ubuntu computer here, even though I have a solid connection. What is needed in the config to let the wireless run in the "back up" internet connection mode?

I tried to look at [URL]... but that webpage does not work. what the traffic might be caused by? Couldn't anyone hacked my pc?
Is there an easy way to monitor network traffic? I want to make sure my kids are surfing safe...
View 5 Replies View RelatedI'm having a problem with my wireless, and after searching the forums for a couple of hours, I suspect it's time to speak up.This morning, wireless was up and working fine on several networks. My laptop froze around noon, and I was forced to do a hard reboot. After restarting, the Network Manager will not connect to any wireless networks, which are visible. Wired connections work fine. I've tried multiple networks, and although I can see them, I cannot connect.
View 1 Replies View RelatedI'm not getting a response over on the Ubuntu WIreless Forum (which looks like it's getting slammed with questions), and weigh in on whether or not you believe I have a hardware failure on my hands? As I state in the post, I ran fine from the original installed version, 8.10, through 2 upgrades (to 9.04 and 9.10). Now none of them work (When the problems began I re-installed each of them in turn in order to test).
View 2 Replies View RelatedI have three computers on the network, one is using Windows Vista, one is in an office room using Ubuntu 10.10, and one is in the living room using Ubuntu 10.10. All three computers have folders shared, and were all three reading files just fine with one another for a couple of months. To share the folders, I just right clicked on them, selected sharing options, and checked the boxes for "share this folder" and "guest access". Both Ubuntu computers have samba installed and configured so the Vista computer can see their shares. Tonight, the Ubuntu computer in the living room stopped being able to see the other computers under places -> network. The other Ubuntu computer and Vista computer can still see each other's shares just fine.
I also created a test share folder with a file in it on the living room Ubuntu computer, and it can be seen by the other Ubuntu computer. I can ping the computer in the living room, and the computer in the living room can ping the other two computers. I set a static IP address on the Ubuntu computer in the living room to rule out an IP address conflict. Under network, if I go to "go -> location..." I'm not quite sure what to type in there to find other computers. Under places -> network, the only thing that comes up on the Ubuntu computer in the living room is it's own shares. I tried using the search feature, but was unable to come up with anything resembling my particular problem within a reasonable amount of time.
