Unidentified network after having installed win vista sp2

    Question

  • Hi everyone

    I have win vista 32 bit and I've installed win vista sp2 recently (through microsoft update) and after that I was not able to connect to the network i used to connect to which is an unsecured one. It says unidentified network, I tried to change setting tcp/ip, I enterend ip addresses myself but nothing changed..same negative results. I succeeded to connect 2 days ago (had no problem) but in the middle of the day it went by itsself and i found my self again with an identified network

    these are the settings when i am connected 'normally'

  • In that case check your antivirus software firewall settings.it might be set to be disabled for unsecured network and allow for others.just temporarily turn the firewall off and see.

  • Hi,

    In addition to drtunababa's suggestion, I would suggest go to the wireless card manufacture's download center and check if there is any update driver for it.

  • It might simply be a physical connection issue(Since it network becomes unidentified intermittently)

    i would advice you to try the following steps. it worked for some facing same issue.

    1. Unplug the internet cable from the back of your computer.

    2. Unplug the power cord form the back of your PC.

    3. Unplug the power cord from your Router (wait 30 seconds).

    4. Plug everything back in starting with the internet cable, power cord, and finally the power cord for the Router.

  • thank you for the reply but i must add that it s a wireless connection, did that already but didn t work for me!!

    the weird thing is that i can connect to other unsecured networks(using the same hp laptop) without any problems (at work for example) ecxept the one i have in my house ...
