Review on πŸ”‡ Optimized PPC FPA6-54 6dB Forward Path Attenuator for DOCSIS Cable TV Box and Modem at 75 Ohms by Brad Blake

Revainrating 5 out of 5

6dB downlink attenuator, cable modem timeouts and reboots fixed

How: Cable modem uplink problems fixed, low cost, no outlet/power supply required. Dislikes: Don't know why it works so well. ** So: before I got this little helper, I thought about buying a return path amplifier like the $40 Antronix RRA1-10 (had used it before for the same problem). The problem was that all power levels were still in "should still work" range eg 0dB downlinks, 45-50dB uplinks, SNR over 30dB but internet connection dropped daily. I had a 6 year old (4x8) cable modem with 4 channels uplink and 8 channels downlink. Switched to a new modem with 4x16 support, but didn't help as T3 timeouts persisted even with the new modem and daily restarts of the modem were evident from the modem logs. Then I installed this FPA and like magic: no more T3 or modem reboots, many days in a row. Now that this FPA is installed it has been running non-stop for over 2 weeks with a pristine clean event log. The strangest thing is that the power levels haven't changed dramatically as they are now -2 to -5dB downlink, 46 to 49dB uplink depending on the time of day. The downlink SNR (direct path) is 35 dB or better and no uncorrectable errors (FEC) are seen on the downstream counters. I'm glad I tried this product first. There were similar ones on offer at a lower price, but I chose this source for its reputation. many days in a row.
