suddenly, no internet connection

[kazordoon]

i have 3 partitions: 2 linux and 1 windows.

i have been using the 3 OS regularly with no problems. But today suddenly, I had no internet connection with the 2 linux partitions which are complete independent, but no problems with windows. i can keep using the internet under windows with no problems.

i haven't touched any conf files.

I have a usb wifi internet connection. any suggestions about where the problem might be ??

edit: I just noticed a change in my dmesg file when i start any of my 2 linux partitions. At the end of the lines I have the following :

Hi and Welcome !

Which distros/versions of Linux are you using? Did you update/upgrade both Linux OSes recently?
