Hello, I'm using a BYO router to go with a pre-existing NTD modem and am having problems properly setting it up. Other than PPPoe I feel like I'm just guessing the settings. This has lead to very intermittent wifi connection, I sometimes have connection but when I look into the router it states it isn't connected to the internet. How do I find out whether my connection is ADSL or VDSL? Should I be using VLAN ID?VPI? VCI?
