Some features that require additional processing of data packets but are not natively supported by the hardware can incur a major performance penalty. These features force packet processing to go through the much slower software-based forwarding path. Access Control is very likely one of these features. Others may include keyword filtering, port forwarding/triggering and QoS. It's possible that the router can handle up to 250 Mbps when Access Control is enabled, but no more. As super high-speed Internet service becomes more common, router vendors have to step up their game to prevent their products from becoming a bottleneck.

While Access Control can be a handy feature for managing Internet access by children, it is not an effective means of security against hackers. All a hacker has to do is spoof the MAC address of an allowed device. This is trivial to do with tools easily downloadable from the Internet. Therefore, if you are using Access Control for security, you may want to reconsider and turn it off. The first and, really, only line of defense for your network is a strong Wi-Fi password.
