wi fi problem

[arondash]

hello guys,

one question, i have just ten hair left now amd still i am after that question.

My notebook is HP-compaq presario V-6000 and i have d-link 110 wireless router for my wi fi connection. There is no problem from my ISP because three other notebooks of the same set up are working fine. Even my internet connection was working fine for 8 months until this day. Suddenly, when i woke up and couldnt connect to my wi fi network. The wi-fi light isnt swtching to blue and always indicate orange colour even if i turn wi fi on or off. If i go to network connections, then i cannot even find my wireless conection icon. In the control panel if i click to hp wireless assistant, then it does nothing.
By bugged at this, i downloaded updated drivers from recommended HP website. and i put them in my wireless assitantce folder in and installed it! after boot it asks for .hwd extention file to open and it doesnt find appropriate program for that, i also tried performing the windows live search but theres no point discussing that as it was absolutely uselss.

one more clue is that..wo months ago my antivirus detected w32:passma, and i deleted some .exe infected from that, i am not sure if this problem is related with that!

so, in conclusion....i just want my wi fi connection to respond to my router set up! I am sure there will be some solution regarding this!

Many thanks!
