6100 network problems - GSM-Forum

thecult · 02-04-2004, 19:05

Hello. I have one 6100 with network problems. It seems ok, Tx and Rx seems good. At start, networks bars go to full level but when you make a call, networks bars start to up and down, going to full level and down level quickly (7 to 2 bars)... some times sound goes bad, metallic, but quickly goes fine... is a strange problem

Because I can't locate network problems in dct4 models I only have updated software but still same

any help please?

thanks a lot

first flash your phone & check its PM , then check external ant. & its connection with mainboard , i think that vibrations which sended from PA is too low , if it was low change PA ......goodluck
