I have a wireless network that I am unable to connect to from this Inspiron 1525 running Windows Vista. The network is detected in the available networks but will not connect. There are two other laptops that have no issues connecting to to the network so I know the router is configured correctly. I have tried resetting the router to default settings with no security but was still unable to connect. Also, I have been able to connect to other wireless networks with this laptop. Can you suggest any other steps I should try?
