NPS Suddenly stopped working. Wireless RADIUS issues specifically

server- nps installed on server 2008 r2 w/o sp1

ap clients- netgear wg103 (with latest firmware 2.0.25)

the wireless clients setup in nps , worked fine month , half.  suddently people weren't able connect.

here list of things have tried:

-the issue seems radius network , in multiple locations. (other networks fine: our guest wifi uses basic wpa key.)

-i have tried stopping , restating nps service on radius clients server

-i have patched , rebooted server, houses radius clients. (except sp1)

-i tried setting nps on a different server and configuring 2 ap’s connect it. (still same issue, @ point i'm wondering if certificate authority.)

-using telnet connect to the server on ports 1812, 1813, 1645, , 1646 unresponsive, yet server says ports open , listening.

-i tried disabling firewall on server telnetting no luck.

-a port scan on server says ports closed, yet server reports open.

-while running wireshark on client; tried connect radius network , got absolutely not packets.  connecting different network, packets come through (if certificate, should @ least see traffic here right?)
