RB411 + r52hn wireless detecting problem

Hi all
I have 2 RB411 with r52hn and till to day all thing are ok.
today my friend suddenly disabled lan and I had to reset RB411.

but after reset, no wireless card detected and I fall in big trouble, anybody have same problem, or any body have any idea?

I reset RB411 on tower and antenna was connected to r52hn, and after rest all configuration back to its factory default and rb411 work normally but don’t detect r52hn!!!

Check the radio card first, maybe it’s broken…
