Hi, I'm just asking out loud, while my router has connected via a dynamic dns, the connection details for my line give manual connection details for primary and secondary connections. While I'm not about to start fiddling, as my connection has just been improved and seems stable, what's the difference or potential benefits of either?
I don't suspect you'd see a lot of difference, however that depends on what DNS servers are being picked up by dynamic DNS and if they were to differ from what's been specified manually. I'd give it a try and see if you notice any improvement.
