Hi Pix,
This site has default parameter:
RXLEV_ACCMIN = -100 dbm ( has been changes from -106 dbm but no improvement)
LAYERTHR = -95 dbm
LHYST = -3 dbm
TALIM = 61
MAXTA = 63
RLINK UP = 52
RLINKT = 36(has been changed from 52 and no improvement)
You have another solution for me except change TALIM,
Thanks Pix,
