View 1 RepliesI have fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.

When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!

On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.
I installed Fedora 14 yesterday via the installation DVD with 3,3 GB. Everything worked fine and when I connected to my wlan and entered the WEP key I got access to the internet. But after about 5 minutes, to connection just got cut and I was again asked for the WEP passkey. But when I entered it this time, the connection failed and I was just asked again (with the same key entered, it even got it saved from last time). As you can think, this is quite annoying, since the time I have internet is not even enough to get some updates done.
Ah, and by the way: The time I have internet it just is unbelievably slow. On my Windows partation, I don't have this problem. I do have a small hint what might be the problem: When I was using Ubuntu, I always had a similar problem, but it did not even connect to my wlan once. The solution was to blacklist some driver, but since I don't know if this might be the problem on Fedora too and if the drivers are the same as on Ubuntu and since I really have no idea about the syntax of the terminal here, I was not daring to try this out.
Hello, I've installed OpenSwan with xl2tpd on my server, and set it up for roadwarriors connecting using certificates.
My server is Debian 5.0.8, I am running xl2tpd 1.2.0, and Openswan IPsec 2.4.12, my clients are all Windows, and I am testing my setup on a Windows 7 client.
I have no problem connecting to the server, but after some time the connection drops. I removed the idle option from the ppp config but it does not make any difference.
Even when I create constant traffic with ping -t the connection drops also.
I have no problems reconnecting right away.
I have been hacking at this for a couple of days, reading every post I can find, but I have not found a solution to my problem.
Here are my configs and logs:

I am having an issue with my wireless connection dropping about every 2 minutes (web pages timing out), then working for a couple of minutes then dropping again. The connection icon in the task bar says I'm still connected at about 70%.I have a dual boot system and the wireless works fine in opensuse but not in Ubuntu 10.10 I have an Asus G50vt-X5 laptop but I am not sure about the wireless chipset.

View 4 Replies View RelatedI am setting up a fresh Fedora 10 install on an older computer for a roommate and have one odd little problem, everything else appears to be working just fine.
The network connection drops after about 2 minutes (somewhere between 90-120 seconds). This only happens in the installed Fedora 10; it does not happen at all when I boot a Kubuntu LiveCD.
Here's what I know:
The machine is a Dell Dimenision 4500, 2.0 GHz, 512Mb ram.
The ethernet card is 21x4x DEC-Tulip compatible 10/100 Ethernet.
Unplugging the ethernet cord and plugging it back in allows the network interface to come back up, grabs the right IP, but only holds it for another two minutes.
ifconfig and route show all the right info while the connection is good, but inet disappears once it goes down.
'ifdown eth0' and 'ifup eth0' do not bring it back up.
Is this a driver issue perhaps?
When downloading a torrent after a few minutes my connection speed stops. Browser also. Same problem with Ktorrent and Deluge. The only way to solve the problem is to reconnect to my WLAN. I use a TP Link WR841N wireless router and a Toshiba satellite pro. The same setup is OK with windows and ubuntu 11.04 alpha3.

View 4 Replies View RelatedHaving struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!

View 5 Replies View RelatedI'm running Ubuntu 10.10. I have a problem with any client side network communication from any java based program/application. I've tried to run the following code:
Code:
public static void main(String[] args) throws Exception {
long start = System.currentTimeMillis();
Socket s = new Socket("ubuntuforums.org", 80);
System.out.println("1. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); start = System.currentTimeMillis();
s = new Socket("ubuntuforums.org", 80);
System.out.println("2. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); }
The result is the following:
Code:
1. connection created in 189.31 s
2. connection created in 0.085 s
I've tried both java-1.6.0-openjdk and java-6-sun-1.6.0.24 with almost the same results. During the extremely long 189 seconds, the processor is doing almost nothing (java thread has 0 %). I've tried also a wireshark to check what is going on, but the first packet was released after those 189 seconds. There is nothing in log files, I have no exceptions or errors, and the connections work (after the first long delay) just fine.
I just installed the Natty Beta and plugged in a Netgear WG111v3 USB wifi adapter. It is using the RTL8187B driver and worked out of the box. The problem it loses my connection every few minutes. Sometimes not for 10 or 15, sometimes like a minute or less. After it loses the connection, I have to uncheck "enable wireless" (which I assume is the equivalent of bringing down my wireless interface) and then check it again before it will let me reconnect. I don't want to try ndiswrapper because the card works great when it works, including monitor mode and packet injection!
View 3 Replies View RelatedI am new ubuntu user . I installed - ubuntu desktop v9.10 32bit. I have BSNL (Indian Telephone service) broadband connection. In Windows 7, BSNL broadband connection is working fine.
Now in ububtu I try to establish ADSL connection using following command: "sudo pppoeconf". It open a console based wizard and I'm able to create the connection. But this connection is sustain hardly 4~3 minute, after that it is disconnected. So, Again i have go through the same process again and again.
I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.
I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.
I buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.
Notes:
- I have another PCI Wireless adapter which works fine.
- The problematic adapter works great on windows.
- A driver CD came with it, including a linux driver which I wasn't succesfully installed.
- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.
It took me dozens of surfing the web hours, and too many restarts,
I'm running Fedora 12 on an Acer Aspire One with KDE. The built-in wireless works without a problem EVERYWHERE except at work. It's a shared wireless connection using WPA/WPA2 security.I can connect but it's "hit-and-miss" if I can do anything with it. Somedays it works well for a few minutes then has a period of inactivity - then slow - randomly receives...It worked flawlessly when the computer was running Windows7 no one else has connectivity issues but I'm the only one using Linux.

View 8 Replies View RelatedI'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69

$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

View 4 Replies View RelatedI have a server which is located in the basement. The server exports a few directories which I mount on my desktop using NFS. From time to time, the connection gets lost. The server is also not always on. I can't change that part, so I worked out a script which notifies me when it's going down, and when it's back up again. It also mounts everything back. However, As soon as I loose the connection, my desktop seems to be gone. KDE doesn't work, but I can use a few applications like Konsole, google-chrome, firefox, stuff like that. But the plasma-desktop around it hangs. As soon as the connection gets back again, everything works. I have this issue only when my desktop is running while I loose the connection to the server. If it's down when I start my desktop, everything works properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.

The computer is a K9n6pgm2+ mainboard w/2gig of RAM and an AMD Phenom Triple Core. My Harddrives are /dev/sda=320gig and /dev/sdb=80gig. Resident on sda is Ubuntu 10.04 (fresh install) w/Windows XP installed at the final 40 gigs, installed after Ubuntu install and then used the 9.10 live CD to reinstall GRUB. On /dev/sdb is Ubuntu 9.10.I installed the fresh Lucid install 3 months ago when I purchased the 320 gig HDD to replace the failing 40 gig and it has run perfectly until yesterday. I presently have a 2Wire Modem located at 172.16.0.1 and I have a new Motorola in the mail but I presently cannot get Lucid to find my internet connection.
If I boot into XP everything is fine. i can go all over the net. If I boot into Karmic, all is well. I am typing this in Karmic so it is strictly a Lucid problem and I have tried all that I know to do and I really want my Lucid install back.
Log file viewer also can't provide much help. I'm also affected by this issue that has been gone on my PC for almost 2 months, now. I've been forced to re-install Ubuntu ( from 9.04 to 10.04 ) countless time. As other users mentioned in their thread, the problems occurred randomly. Sometimes right after start-up, sometimes after 10 min to an hour of PC usage and sometimes no freeze at all. But the symptoms seems similar though on different component of hardwares. Me, myself, my PC always started to display freezing symptoms after 2-3 days of any Ubuntu fresh installations. The only way to re-boot are through RSEIUB/O ( and luckily I've never failed to do so ). Its just maybe took countless time of Ctrl + Alt + Del, before I could enter Grub menu and after that Ubuntu. Seems like that BIOS doesn't recognize HDD ( where the Ubuntu situated ), but oddly it ( BIOS ) only rcognize the CD/DVD drive . Lately, to overcome this HDD problem, I tried to pull out the SATA cable connected to CD/DVD drive and left only the SATA cable to HDD. And guess what, I've never encounter this unrecognized HDD problem for the past 2 days. I suspected the cause off all this issues are maybe the AsRock G31M-VS2 mobo that I've just installed about 2 month ago. But certainly, this issue never back me off my love to Ubuntu. As long its Open Sources.
