Hello there, I have been using Compaq Presario 2700 laptop which had Windows XP operating system installed on it. Recently I upgraded the operating system on the laptop to Windows 7 and from that day I am not able to connect to the wireless network. Wireless internet is provided by Dlink wireless router. I am not a networking person and hence cannot figure out what is causing such problem. Therefore if any of you experts know why Compaq Presario 2700 does not connect to Wireless network then please help. Thanks in advance.
