General :: No Network Packets Sent Immediately After Quick Physical Disconnect And Reconnect?

Mar 9, 2011

I am using tcp for data transmission between 2pcs running linux.During transmission, I have noticed that if I unplug the network cable and reinsert it quickly,connection is not lost(same as i expect)and the sender start to resend the packet after 5s(what i expect is that network packets sent immediately after quick physical disconnect and reconnect).My question is can i reduce 5s to 0s(resend immediately after network cable reconnect)?Any parameters(tcp rto,txqueuelength,..) can be modified to achieve this condition?

Ubuntu Networking :: How To Automatic Ppp Reconnect If Down

Mar 5, 2010

I didn't find a solution to making my 3G/GPRS "modem" reconnect automatically when the connection fails, so I made a solution of my own. It's very annoying when you're downloading a file overnight, only to find that the connection has failed 5 min after you went to sleep.Restarting the NetworkManager daemon makes it automatically connect to all configured interfaces, including 3G/GPRS, so I made a simple script to do that.First, we check if the modem is even connected. Replace Huawei with the brand you're using. Any unique word on the line in lsusb will do fine as well. Then we check if the connection is up, and if it is, we simply exit. Otherwise, the NM daemon is restarted, which causes the 3g/gprs to reconnect.

Ubuntu Networking :: Rt2500pci Fails To Reconnect?

Jan 29, 2010

wireless disconnects after a few hours, there is a 50/50 chance that the reconnect fails. if it fails i am asked for the wpa2 key, if i hit cancel and try to connect manually after 2 minutes it connects most times. if i enter the wpa2 key and hit connect i won't get any connection. reading the loglife of my router shows that my laptop connects and disconnects in a 7s rhythm. a restart solves this problem (is there a command to manually restart the network without the need to restart?

laptop: packard bell easynote w1000
ubuntu 9.10
lspci -v readout:
Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)
Subsystem: RaLink Device 2560


probably related, after suspend or hibernation networking is disabled, enabling it via right-click does not work again after a restart everything works how it should.

Ubuntu Networking :: Internet Shuts Off And Cannot Reconnect?

Sep 21, 2010

I just started using Ubuntu at the advice of a friend. I am running it from a flash drive.I have a wired network that always works fine with Windows on this computer.After starting up Ubuntu it connected right up and I was able to use it. Then, out of the blue the machine shut off. Upon restart, I was unable to connect to the internet.I reinstalled Ubuntu to a different flash drive and it worked fine once again.I left the computer running while I went out for supper, returned and the computer was "asleep" and would not wake back up.I shut off the computer and restarted Ubuntu.No internet again. As always, it works fine in Windows.Also, BOTH times this has happened, the OS says I am connected to the internet, and I can turn the connection on and off, but it is not connected. This happens even if I reboot the computer. (I have a cable connection.)

Ubuntu Networking :: Wireless Won't Reconnect After Dropping?

May 26, 2011

I'm having a problem with the wireless on my Asus EEEPC 1000HE using Ubuntu 110.04. Digging into the laptop forums, it says there is a problem with wireless on some models of the 1000HE, but it is not the same wireless device and my wireless problem doesn't seem as bad as listed, so I think it's a different problem. But my problem is that if wireless drops for any reason, it will not start working again unless I either reboot the computer or click the wireless icon in the systray, click disconnect so it stops flashing (like it's trying to reconnect) and then suspend my computer or log off and back on. And it only does the latter because I added a file located at /etc/pm/config.d/00sleep_module with the one line that reads SUSPEND_MODULES="rt2800pci" (my wireless driver) So that one line seems to cause wireless to get a fresh connection after suspending (or something. I'm not a very advanced LInux user). I've tried running the command "sudo/etc/init.d/networking restart", but that does nothing for me. I'm not sure what other command to try to see if can fix it.[URL]

Ubuntu Networking :: Can't Reconnect To Internet After Disconnecting

Aug 16, 2011

Here is my problem:

I can reconnect to internet after disconnecting (this happens every 3-4 hours) only if I manually poke out and in ethernet cable to network adapter or reboot ubuntu. Even restarting network-manager not helps. My provider provides internet over pppoe. I have "DSL-connection 1" item in network managers gui menu. And that item disappears after disconnection.

pppd runs with following arguments: lcp-echo-failure 3 lcp-echo-interval 20 So where can I change this parameters, where is that configuration file?

Networking :: Wifi Won't Reconnect After Standby Or Hibernate

May 3, 2010

I am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address. And if I try to change networks without hibernating I get the same problem. Also, I notice that the network name is stagnant. I connect to multiple wifi networks a day because of school. When I leave my "home" network and connect to my "school" network WICD still says "Homebtaining IP address" even thought it should say "schoolbtaining IP address." My thoughts are that it isn't releasing the network properly and when its trying to connect it can't because it still thinks it's connected. The only solution I have found is to restart my laptop every time I want to connect to a new network, or shut down every time I am done using my laptop, which is a major inconvenience.

Here is what I am using:

HP tx2000
Broadcom BCM4322
Ubuntu 10.04
WICD 1.7.0

Networking :: Unable To Reconnect To Wireless AP Using The Same Settings?

Mar 3, 2010

Sometimes I am unable to reconnect to my wireless AP using the same settings that worked the previous day, and that has me stumped. I think it's due to me switching access points (using different authenticatin) since the last connection.

1) After I enter iwconfig/iwpriv commands to connect my wireless usb card (edimax) to my WPA2 network, what process performs the negotiation with the AP, and is there a way to see status debug messages from that process so that I can see if there was a successful negotiation? (so I can see if the password is correct, etc).

2) Is there a way to manually invoke that process to re-attempt to negotiate? Or must I assume that happens automatically with any iwconfig/iwpriv command?

3) Is there a simple command that will erase all iwconfig/iwpriv settings so that I can start over with my iwconfig/iwpriv commands?

Networking :: Ubuntu Can't Reconnect To Gmail After ISP Restores Access / Fix It?

Dec 31, 2010

Lately, my ISP has started making all Google sites inaccessible for a short time every afternoon (last 3-4 days now). I suspect some kind of DNS poisoning... access always comes back later in the afternoon.

When access does come back, non-Linux machines can connect basically right away, but my Ubuntu machine (the primary one I use) seems to need a reboot, as if wrong DNS information gets stuck in the session and the reboot clears it so that the machine can get the correct IP address.

I have not installed nscd, and IIUC the OS should not be persisting DNS cache information without that package. Every reference I can find online to clearing the DNS cache seems to depend on this package.

The objective is just to get back in touch with my Gmail without having to reboot (since e.g. OSX doesn't require a reboot for the same). What should I do?

Ubuntu Networking :: Wi-fi Disconnect Every Few Hours?

Fedora Networking :: Unable To Reconnect To The Internet When System Comes Out Of Hibernation

Aug 10, 2009

I am having a problem reconnecting to the internet when I put my computer in suspend or hibernate. For some reason when I put my computer in any one of these modes it disconnects from the internet, and I have no way of getting back on the internet after that. I use to have the option of "Enable Networking" on my top panel, but it seems to have disappeared for some reason. Is there any way to stay permanately connected to the internet, even when it is in hibernate mode, or could someone tell me how to get the enable networking icon back?

Ubuntu Networking :: Reloading Hostapd On AP Side Permits Wicd To Reconnect

Sep 21, 2010

I'm running WiFi AP (hostapd/nl80211) and STA (Wicd) in my home net. More or less all does work fine at last. The only problem I have - STA reconnection works few times only (1-4 times), ending with unsuccessful authentification (and multiple AP probing in hostapd debug output before STA failing).Two contradictive facts take place:

1. Reloading hostapd on the AP side permits Wicd to reconnect, while STA rebooting(!) doesn't help.
2. Another STA - my son's Nokia mobile phone (don't know a model) - reconnects with this AP without problems (we have tried 10 times).

So, you see, first fact says something wrong with AP, while the second one says something wrong with STA. Or you can treat these facts in strictly opposite way Indeed WiFi under Linux is very fragile area yet. I have found plenty of close-to-be-similar reports as well as different resolving ways (but it is rare case).OK, few words about setup. Up to date Kubuntu Maverick testing with backports enabled on both sides. ASUS USB-N11 adapters are in use on both sides. It means RT2870 chip.

Ubuntu Networking :: Mobile Broadband Connects / But Won't Reconnect After Dropped Signal

Nov 8, 2010

I'm running a ZTE MF112 HSUPA USB stick (3 broadband dongle) for wireless broadband using network-manager.I can connect fine to mobile broadband, but every now and then, the signal drops and the connection is disconnected. When I try to reconnect it goes straight to network disconnected. It looks like it's not even trying to connect.Then when I right click on network manager, disable mobile broadband, then enable it again, works fine until the next disconnect.The point is, why do I have to keep disabling / enabling it? Pulling the dongle out works too. But there should be a workaround.
