    Is it only the computer that loses connection, or other devices too?

    Txs for your reply. It is only the computer, As I told you the wi-fi icon tells me that the network connection is ok. But I can not get access to the internet. Sometimes, my impresssion is that it happens when I am using Google Docs. Regards.

    We can do maybe an experiment...  plug an ethernet from the modem directly into your computer. And keep an eye on it to see if the problem still persists.

    Thanks for your reply. Let me try to make the problem a bit more clear.  My problem with the wi-fi happens only with the imac. My bookpro and my iphone and ipad int he same place  as the imac access the internet with no problem.

    The problem in the imac is that it changes network configuration withe the following status message appearing in the Open network preferences:

     

    Wi-Fi has the self-assigned IP address 169.254.22.50 and will not be able to connect to the Internet.

     

    when it should have

     

    Wi-Fi is connected to REIS and has the IP address 10.0.1.3. or something like taht to work

     

    The problem is that the imac keep shifting sometimes in minutes from one configuration to the other.

     

    Is there any suggestion or solution?

     

    Grateful

    Hmm!

     

    Looks like we may want to pull the System Configuring folder and see what happens...

     

    Go to MacintoshHD, then go to Library/Preferenes

     

    Drag your SystemConfiguration folder into the trash (it will ask for a password).

     

    Then re-start so the OS creates a new folder with defaults. Re-join your network, and see what happens.

    Thanks for your reply. I did follow your instructions but after one day the configuration of the network started shifting again in the same way. Any other suggestion? Grateful

    Hmm!

     

    Time to dig into more info.  Who is your ISP, and what rooters are we using here?
