Very curious as to what that (junction?) box does?
I would recommend a new SSFP for you, burakkucat. It might eek a few more Kilobits out of your line
I do have a MK2 SSFP available (currently unused) should you want it?
It looks ...... err ...... ok, and not service affecting in any way ......... but I'm certain I could have made that a more aesthetically pleasing installation. In fact, I'm damned sure I could.
