I just bought a new Acer laptop and have Windows 7 pre-installed in it . It was great pleasure spending big time with my new laptop, but all those pleasure worn off when it came up with its first I have got an unlimited plan from Comcast ISP service provider. I am trying to connect it i wireless connection but for some reason I am not able to connect it. When I check the signal strength it shows a healthy signal, but while opening the browser it shows limited or no access. Please let me me know if you have solution for this problem. I forgot to inform you that I can connect it successfully while I use a wired network.I use a DI-524 router .
