Hey all, I have got this strange problem with my Slackware server acting as router and gateway to my internal network. It randomly disconnects the WAN connection after X days ( it is between 2-7 days ). This error messages occured in /var/log/messages just before it lost its WAN connection:
Feb 20 14:36:00 tml dhcpcd: eth1: failed to renew, attempting to rebind
After upgrade to Lucid I have experienced intermittent wireless disruptions. The wireless just cuts out and reconnects.And I was hoping to continue or follow up on the same thread however with the released version.I tried replacing network manager with wicd and I tried the other driver options both without success.I'm currently using the Broadcom B43 driver, when I tried the Broadcom STA driver wireless would not work. I use the 64 bit OS, and this problem did not appear prior to the upgrade.
View 1 Replies View RelatedI'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.
I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.
I have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.
If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.
When I first turn it on to the desktop, it automatically connects and disconnects automatically 5 times then sometimes it would disconnect a few times randomly out of the blue.
This ia an external single usb wireless adapter you plug in the usb port on my desktop tower.
I recently installed Fedora 14 on my machine. Ever since I cannot connect to the Internet at home.henever I plugin in the ethernet cable the ADSL router disconnects and all machines connected to the router lose connection to the Internet.
View 9 Replies View RelatedI'm having issue with my wireless connection. I'm not sure if it is the WPA security causing the issue, but I randomly lose connection to the router. The network manager then scans for available wireless routers for a bit before trying to reconnect to my router and asking for my wireless password again.
View 3 Replies View RelatedI have two computers and a wi-fi router. A notebook with Ubuntu 10.04 and a desktop with Windows 7. Whenever the notebook is on, the desktop starts having horrible Internet speed, and eventually disconnects. If I turn the notebook off (or disconnect from the network) it starts working fine again. Both computers connect to the router via wi-fi. I should also note that the connection runs flawlessly on Ubuntu.
View 3 Replies View RelatedRunning Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).
It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.
I have loaded ubuntu Lynx 10.04.1 as a dual boot behind XP home. I have wireless connection to the XP os via netgear wireless G router and USB 2.0 adapter. The network connection works well with the XP side. When I boot into ubuntu I am sure I have configured the network properly with the wep key and password and the network signal is alive in the work bar at the top of the screen. When I open Firefox and try to browse to ,say, ebay it asks for the passphrase again then tells me that FF is in work offline mode. When I correct this I get asked for the pass phrase again and the connection is disengaged. It just keeps asking for the passphrase and disconnecting. When I reboot into XP everything works perfectly again.
View 9 Replies View RelatedI'm not sure if this started with the 2.6.34.4 or 2.6.34.7 update, but one of those.At random intervals the USB subsystem disconnects. When that happens the monitor screen goes black (no input signal) and then returns 1 - 2 seconds later. This was happening every once every 1 - 2 days; today the count is 10 times. It's gotten really annoying.There is a topic about USB mouse and keyboard becoming unavailable due to recent kernel updates. That is not the issue here; I have tried disabling USB auto-suspend with no observable change in behavior.Or could it be that I have a defective mouse?

I couldn't even get enough internet to post this from my laptop so I had to post this at school from a windows. Idk whats going on but it sucks because I cant really use the comp without the internet..

View 3 Replies View RelatedI use a secure connection to reach company network from outside. There's a client application "Juniper network", which creates the secured tunnel to a company network. However, the connection never survives more than 8 seconds, when it goes disconnected with the message "Route monitor alarm". From my recent search for a solution I've found that this error is caused by a change in a route table, which violates a connection policy.
"This disconnect is typically triggered by a change in the routing table of the client machine, the change is such that the split tunnel policies defined by the administrator will be violated" - from [URL]
This is how a routing table looks before, during and after the connection attempt:

I have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behaviour when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information.

I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
I have a windows installation (partition) but have installed into freespace on the same drive using the auto-partition manager, etc, and everything is fine. I got my network going fairly easily by going Preferences > Wireless and inputting SSID and WPA encryption key (PSK). My router issues an WLAN IP, I can get on the net, I can see my other Windows PCs on the network, I can reach my router, and all is good.So after several hours of mooching about and looking at things, I have updated all the Linux packages via Synaptics (following a prompt to update everything) including GRUB. My dual boot now shows two versions of the OS:
GRUB 1.7~Beta4
Ubuntu, Linux 2.6.31-19 - generic (I am booting this one)
Ubuntu, Linux 2.6.31-14 - generic
I also set up my HP F4580 printer over wifi on the network though with slightly incorrect drivers (for the F4400 series as this was recommended at the closest match). It works, and I can print a test page no problem.The only thing is that now (since doing all that) Ubuntu seems to periodically drop my connection to the network and then request the network PSK again, but when I enter it, it spends time trying to renegotiate but fails, and then re-requests the PSK, over and over and it never reconnects. I have to reboot and then I can connect again (automatically), until it drops at some random point (like 5 or 10 mins later)
I could not find a solution to this problem anywhere. I use a ubuntu server to play (stream) mp3s and movies to other computers on my network. It works most of the time, but sometimes in the middle of a movie or a song it will drop/hiccup--saying it is "not reachable". I am not overtasking the server at all, and merely playing an mp3 that takes up less than 10% of the bandwidth, yet it drops it for a split second.
I have a WRT160N router (DD-WRT of course) with 4 clients connected (2 of which are wired). The ubuntu server is connected via ethernet and all machines have the same issue. It can't be the router because another Windows machine works just fine for streaming these files. I just can't understand how it can lose connection for a second or so. It may just be the file-system or some service that is hiccuping, but I have no idea...
I do randomly (as far as I know) loose my wireless network connection. The only thing to do then is to restart my router and after that it works for a while. I know this is not a hardware issue because I don't have this problem with KDE, only in gnome. I think this problem occurred after I started using 10.04, but then I changed to KDE and forgot about it. But now I'm using gnome again and loosing my network connection over and over drives me mad

View 9 Replies View RelatedI am running the newest version of Ubuntu on my laptop. The connection randomly seems to massively slow down. After a speed test is run it registers at .05 download and Ubuntu crashes before it gets to upload. I reboot from the crash and it runs fine for a while, then it suddenly does the same thing. The connection is running fine on my Windows 7 desktop, I don't know what is going on. In transmission the upload speeds are running at ~100kbps though. If I try downloading a mere 400kb .torrent file it stops half way through, usually at 200-300kb done, downloading at 1.2kbps the entire time. This is getting very frustrating and I really don't want to go back to Windows.

My ubuntu karma desktop is plugged into a wired connection that goes through a router and into my cable modem.Everything was working fine like it had been foseveral months yesterday morningSomething happened by the end of the day that has screwed up my wired networking. I plugged my laptop into the same cable thats plugged into my ubuntu, and the cat5 cable is live. Also when I plug said cable into the ubuntu box, the ethernet lights come on, or atleast a solid green one. Meanwhile the network connections Icon continues to have a red X and a tooltip saying "No network connection".
Under network settings, there is only one wired network "Auto eth0", but it says "last used: never" which is strange since I've been using this for months. When I click edit the main settings are MTU automatic, ipv4 automatic DHCP, and ipv6 ignore.hat could the problem be? By chance did a karma update get released that broke the networking
The title pretty much says it all. My eth0 will disconnect at random intervals. lspci:

Prior to the install of Xunbuntu 10.04 (Lucid Lynx) the machine carried MSXP. The wireless card came with the machine. The machine used a cable connection by previous owner. Connection's been working fine in Ubuntu Jaunty Jackelope and Puppy Linux. Wireless card appears to be functioning. The system scans for the network, shows that connection is established by both icon in tray and message saying that a connection is made. The card shows both green lights active. The light that indicates a connection is on and randomly flickers. Tested Firefox for connection. Firefox is not receiving anything from the system. I have got the network manager functioning enough to say that I have a 'connection' but still cannot connect to server.

Help menu in 10.04 is listed as help menu for 9.04 so don't know if applicable to 10.04 debugging. When 'troubleshooting' wireless connections, I did a *sudo lshw -C network* command on terminal. The results *do not* show 'Claimed, Unclaimed, Enabled or Disabled as help menu indicates. The line that would show that information (*-network) doesn't have 'Claimed, Unclaimed, Enabled or Disabled'. I can send image of this query. I have tried two other wifi cards with similar results, no connection.
Since I installed Ubuntu I've had this problem that makes me loose connection to the Internet. The wireless-icon on the panel starts loading, and after like 5 minutes, it works again.I had this problem when I had Mint 11, but it happened more often.Anyone know how to fix?

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.
