Yesterday our suburb had a 20 min power outage. I have a DLink DIR 615 Router, with 3 PCs using the Ethernet cable ports, and, 2 laptops, an iPAD and iPOD using the Wireless access.
Following the power outage the laptops could not access the LAN/Internet, as, I found out the router had reset itself to Wireless default, so that the password access/security was different to that "remembered" by the laptops. Reset of the security and password solved the problem, however, my query to any Wireless gurus, is that the iPAD and iPOD could still access the Internet when the laptops could not. Is it something to with the LAN ? PCs are 2 x WinXP and 1 x Win98SE
2 Laptops with Win7 Home (Or does Apple do things differently?) :-)
