I just purchased a Dell Latitude 6500 lap...

hi! there is no problem with your internet connection with your router but the problem is your dell lattitude wont connect to the wireless network, please try to disable your dell software for connecting to wireless network and just use the windows wireless zero config, check the on the taskbar on the lower right of the monitor, there is an icon for the wireless connection for dell, right click it and select disable, sometime there is an option that windows will ask if you want to turn on the wireless zero config..if it didnt ask, click onn start, run and type in service.msc then it will show the services go to the buttom portion and enable the wireless zero config..
