5.3 Before You Begin
You need to know your Internet access settings such as encapsulation and WAN IP
address. Get this information from your ISP.
5.4 The Mode Screen
Click Network > LAN > Mode to open the Mode screen. Use this screen to set
whether or not the Device uses PTM over ADSL. Since PTM has less overhead than
ATM, some ISPs use PTM over ADSL for better performance. Select or clear the
option for PTM over ADSL and click Apply to save your changes.
