My parts:
- Cable Modem ES2251 DOCSIS 3.1 eMTA (frequency 108 -1002MHz per manual)
- Splitters is GE 5-2500MHz
- MoCA filter 35-45dB of rejection in the MoCA 1125-1525Mhz
Initially, I added the MoCA PoE Filter and the two Splitters, and it all tested good with full speed Internet. As soon as I install one of the WF-803M, the modem will go offline, and it will not sync with ISP. If I install both WF-803M, the Pwr and MoCA LED stays on, while LAN flashes, and I can ping upto the router. If both WF-803M are disconnected, the modem syncs and all work without issue.
Below diagram is my setup. Please help.
There could be various reasons why you are unable to connect to the internet, but here are some frequent modem-related issues: Remove any loose power or coax connections. Ethernet cable connections that have been connections damaged. Communication breakdown with the router.
