I have my ipod a desktop and a laptop all utilizing the wireless connection from our main computer. Everything was working perfectly until my 3 year old touched some keys on my laptop. Now, my wireless connection shows and works on my ipod and desktop but not on the laptop. I can see other wireless networks just not mine. I called technical support and they say it is my internal wireless card but this doesn't make sense to me because I can see other wireless just not my home wireless. Any ideas, please?
