QoS settings on a router at home!
i have a couple of crucial questions related to QoS. i possess two computers at home which access the Internet via Linksys WAG120N DSL+2 broadband modem. i know how to set QoS on that modem. However, i need to learn a few things.
1) At QoS settings page, when i intend to prioritize the traffic based on MAC address, how do i know which MAC belong to which NIC on the router settings 'without going to that specific computer? ' (imagine if we had 50 computers, we couldn't go for each to recognize the MAC for each computer)
2) Could ISP 'limit' the traffic/bandwidth to any website and how? (for ex. while we are trying to watch movies online)
