In wireless network applications, sometimes the IP addresses of wireless APs or wireless routes are often forgotten and cannot be accessed by a browser. Common solution, press the reset button to forcibly restore the factory settings. If you just forget the IP address, you can also scan through the LAN IP to find out the IP address of the wireless AP or wireless route.Advanced IP scanner

: 135Services: Location ServiceDescription: Microsoft runs DCE RPC end-point Mapper for its DCOM service on this port. This is similar to the capabilities of UNIX 111 ports. Services that use DCOM and RPC use the end-point mapper on the computer to register their location. When remote clients connect to the computer, they look for the location where the end-point mapper find the service. Hacker scan the computer for this port to find running Exchange
