is mikrotik support D-link dwa-525 wireless adapter
only (yes or no)

Plz tell me or Suggest best wireless card for x86 pc

There isn't much out there in the way of PCI 802.11n products. TP-Link TL-WN851N, Atheros Based (2x2MIMO) or the TP-Link TL-WN781N, Atheros Based (1x2MIMO) should work, but I haven't personally tested.

You can always check the Mikrotik Hardware Page http://wiki.mikrotik.com/wiki/Supported_Hardware

Additionally, you could use the Mikrotik R2N, R5N or R52N miniPCI Wireless N adapter in the RB-11 miniPCI to PCI Adapter to acheive the results you want. Look for all of these here: http://www.routerboard.com
