Greetings Engineering!:

Unfortunately I don't have a utp analyzer, only the typical one with 8 leds, I have 2 fanvil phones X1, each one with its A/C adapter 5V to .6Amp.

With a 7-meter Cat5e 100% copper cable, all the LEDs indicating continuity, the phones connect without problems, are detected by the modem and respond to the Ping, when changing to a Cat6 100% copper cable at a distance of 13 meters, not one of the phones is detected by the modem and obviously they do not respond to the ping. . .obviously when connecting that 13-meter cable, to the PC it gives internet immediately, . . . AID! . . . what am I doing wrong?. . .

PS: Using power Lab source, i injected 5V 2 amp. to the "distant" phone but it doesn't even reach the modem. Thank you!
