Settings 1
Settings 2
These are what it is set to at the moment
Clutching at straws here because most would say that those settings would be fine.
Comparing my settings I do have an Entry for Service Name and I have set the MTU at 1520. Also the adsl setting is shown as PPPoA.
I do have the DSL mode as AUTO though.
Perhaps not having a Service Name is problematical for the connection to stay up.
It is quite rare for the configuration for an ISP to use MPoA but that might be the case.
Could really do with a screen shot of the Dashboard though.to check for anything else that might not be correct.
