They can see the connection is dropping multiple times a day, but they don't know why, there tester doesn't pick up a problem. Gary's dealing with it by sending out a new router just to make sure it's not a PSU fault or something like that. TBH if it is SHINE, because it is an intermittent fault, it will be very hard to pick up. 9.5km of cabling, it could be anything from a wet joint (which is what i believe it to be), to a rubbing tree branch, to a TV, radio or even microwave anywhere along the line. and it's so flipping hard to get a specialist REIN engineer out instead of just a boost, where there test's see nothing as well. our line achieves a very good speed for the length, 2.5mb just about. and even capping it at 1 or .5 it still drops.
i think the next trick up my sleeve will be to involve the or area manager for some end to end testing.
