I've replaced my wireless router with a D-Link DSL-2740R. I followed the quick-setup instructions on the supplied CD and managed to get online using our cable-broadband service. I now want to add my Netbook and BlackBerry to the wireless network.
I couldn't get the BlackBerry to connect to the network using WPA2, so I instead used 128bit WEP. The netbook will go online, but the network symbol in the Taskbar reports that it can't validate the wireless network. The laptop threw up the same error message, but wouldn't go online at all. Andy625
It's often tricky to introduce a new wireless router to a network. Have you given the new router the same service set ID (SSID) as your old access point? And are you using - or trying to use - the same wireless security as your old router?
If you've already checked these settings, you'll need to delete the wireless connection and let Windows set it up again. You should then do the same for the BlackBerry. You should definitely be using the WPA2 security settings rather than the far less secure WEP and different passwords, too.
