Hey everyone, I am every new to this router configure, and my boss just asked me to configure this CISCO 877W for the office network. I have tried my best to get codes from everywhere and put them together. However, it doesnt work, please could anyone point out the mistakes please. Thank you so much for your help. I put the router on the DSL line, the PCs can get IPs from the router, and also I could log into the router. But there is no interenet connection, also I cant ping anything from the router. We are using BT ADSL2+ connection, PPPoA.
