Hi Lily !
Still alive and working hard, I see !
Could you recap the N3103 mechanism ? Is it the one where the MS does not send the final acknowledgment, which is actually kind of useless anyway ?
I think it is a good idea to increase the LIMIT, always good to test something.
I don’t think the MS are at fault though, especially if the degradation starts suddenly and go as high as 30%. If possible try to do a trace (Abis/AterPS)
Cheers
