wired and wireless internet stopped working all of a sudden

[linuxbee]

Hi all.
I am experiencing a really weird connection problem that I haven't seen before.
Basically both wired and wireless internet has stopped working.
To be specific, it looks like my netbook is connecting to the router both with wire and wireless, however there is no internet connection.
This problem has been persisting yesterday, and it doesn't make sense because nothing has changed in my computer recently. No updates, or anything like that.
I have searched through linux forum but couln't find anything useful so far.
Any ideas on this problem will be very much appreciated.

My problem is partially resolved as follows.
At some point, I checked out the following file /etc/resolve.conf which looked like

Code: Select all

domain Belkin
search Belkin
nameserver 192.168.2.1


which is the stuff associated with the wireless router, and the above information wasn't correct for the wired connection.
So, following the content in this page: http://swift.siphos.be/linux_sea/networkmanagement.html, I replaced

Code: Select all

 search Belkin

with

Code: Select all

 search lan

.
And also added the correct DNS server ip addresses like

Code: Select all

nameserver xx.xx.xx.xx

.
After then my wired network is working.
My conclusion is that even though my eth connection had the all correct information regarding internet connection,
it somehow didn't propogate all the way to /etc/resolv.conf file even though I restarted network services many times.

This happens to me too. Had that problem with mint 13 and now with 14. Although it seems connected it stops working unless I reconnect.
I know this will sound crazy but i think there is a connection with downloading torrents. When torrent program is off everything is fine but when I'm downloading sth it stops all the time
...BUT !!!
...this happens only when I'm dowloading slow torrents! when I'm dowloading at about full speed it's ok! ?
I'm sorry I can't help I'm very new with Linux.

i found out a sollution here "http://gamingtrend.com/forums/hardware-software-hell/downloading-internet-connection-problems-%28torrent-related%29/".
Seems that UDP connections were causing the wifi card to have issues so I installed " udptunnel " (a program which can tunnel udp packets bi-directionally over a tcp connection) restarted and now it all looks well. Can't tell yet if and how much it affects my speed.

Well... It still stops from time to time but at least it's better now... It started happening again after some days...
If anyone has a better sollution plz tell.

Take a look at the suggestions I've made in these 2 other posts. Maybe one or the other could help you.
