Your router probably has problems with the Intel. I have no problems whatsoever with my Intel Dual Band Wireless-N 7260 (16.1.5.2 drivers) on an el cheapo $30 Netgear WNR2000 v1 stock latest firmware as well as my university's campus WiFi with Aruba Networks enterprise access point and WPA-2 Enterprise / AES security. Never have a drop with the WiFi and I've gone through more than 1 GB of send and 2 GB received data over 14 hours and 30 minutes.
