hi.i have a d-link adsl modem and i want to share internet for my clients on local network, but when i connect it to switch, its port disable immediately, my switch works well and i use it,but can't connect adsl to switch.
- Presumably there is a conflicting port setting for the designated connection (where the adsl modem is connect to) ; check the switch logs when the port gets disabled ,
but when i connect it to switch, its port disable immediately
