Balance 380 interface thru put

Can any one tell me what revision of the balance 380 will have a gig interface
I have Comcast with 175 meg and my 380’s will only pass up to 80 meg. One 380 is rev 5 the other is rev 1
If I speed test directly from Comcast router/modem I get 175 + meg
thank you
Rob

Even the older 380’s supported up to 200Mbps of throughput so I recommend to open a support ticket for further investigation:

Thanks.
