From a cmd prompt:
netsh wlan show interfaces
The BSSID entry in the output is the MAC address of your access point. To find the corresponding IP address use arp -a; e.g.:
arp -a – list all ARP entries
arp -a <ip_addr> – list IP entry for IP address <ip_addr>
arp -a | find "<mac_addr>" – search output of arp -a for <mac_addr>. Useful when you've already used netsh wlan to find the access point's MAC address.
I use Network Analyzer.
netsh wlan show profile name=wifinetworkname key=clear
