the point of the above is your asking the exact same question as last time (and i dont think it's the only time but i cant be arsed to read any more)

personally i think it's a signal issue, the quickest way to test is to flash a subbed backup to your modem and see if it connect at all times

if it does work and i am wrong, that flash a better nonvol to your modem
