I don't remember seeing this problem at work where they use Cisco routers. I see the problem at home with my Speedport 723V Typ A router (a+b+n mode, WPA2). This may be affected by number of other wifi networks which are visible here: at least 17 at the moment. 03:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 73) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4470] WORKAROUND: /etc/modprobe.d/iwlwifi.conf : options iwlwifi 11n_disable=1 Drops did not cause loss of my network, and reconnects happened mostly in the same second. However at some moments there were just too many drops.
