I need Help. My Wireless network tab is missing on my Windows xp operating system. I use a Acer Aspire 5000 Laptop. I was doing some anti virus cleaning and when I restarted my Computer, I could not get my woreless connection back on. Looking into the system, I discovered that my Tab was Missing. I spent the last couple of days on a friends laptop looking for anwsers and found none. Can anyone please help me ???
