These past 2 weeks my pc on the roof displays a random problem and when that happens ONLY AR52N cards stop working and they "freeze" with an "R" still showing like they are working, the AR52 cards are immune to the problem. The problem is displayed in more than one forms, that is some times the pc becomes unresponsive (dead) but its still fully on, sometimes it restarts with the AR52N interfaces MISSING, less often it shuts down and sometimes just the N interfaces freeze and the AR52 cards still work.
The problem happens after 2-3 hours after reboot and effects only the N cards the AR52 are immune to the problem and i am using Nstreme on the links and the cpu usage is around 40-50%. The problem started after more or less 2 weeks of making a link with the interface called "Mastoras" the interface was already in the pc just dormant without a link, maybe this is some kind of hint. Also activating the interface "Mastoras" would sometimes force the interface called "Jkond" to drop its link. Now these days the problem has " settled down " a bit there are no shutdowns of the machine no restarts, the computer is stable with the N cards present but NOT working.One more thing that comes in mind that may as well be another hint is that applying the backup file i attached seems to fix the problem for several days, and updating to a newer version also seems to fix the problem temporarily
Do you have any ideas about my problem and what i should do, can i format my pc all over again ? but i guess this will cost me
?. what over info do you need except my brief description ? i will attach a .backup file and some pictures hope this will help in understanding my setup. Please let me know what i can do what are your suggestions in order to fix the problem cause the pc is giving me some serious grief. My specs are:
