We've been having a Zyxel NBG-416Nv2 N150 Wireless N Broadband Router and there are times where the Wi-Fi speed from the usual 55/mbps drops to about 1 or less, especially around midnight. I've tried to change the Wi-Fi Channel and update the firmware, but it hasn't helped. The area is fairly congested and the router needs to provide Wi-Fi to a household with 8 people. Please give me suggestions to fix this issue. Any help would be appreciated!
