we always want to make the most of our products when we use a product. We broadband internet is also the same mentality, how to make ADSL the fastest, the best effect? Under the existing hardware conditions we can only optimize! Windows Series when installed, the default is for Ethernet settings, in the TCP/IP packet transfer process will be some of the work in the subcontracting and combination to adapt to the ISP. Although ADSL use PPPoE protocol, with the characteristics of the LAN, but not
