Q2400A, rare probs with connect


occasionally it is hard to get a data connection in spite of good CSQ values and if i get a connection it breaks down immediately or it’s not possible to send/receive data, but all other functions are still working. if this happend, the module keeps staying in this state until hardware reset. maybe there is a newer firmware for my old modules?



sometimes this happens due to improper power supply or some kind of grounding problem.
