WF-803M no longer appearing on network

I have had two WF-803Ms I've been using as the backhaul to connect my main mesh router and satellite for over a year now with zero issues. I suddenly and randomly started having random disconnects and stability issues with devices connected to the satellite (wired), despite not having changed anything on my network.

I discovered that there had been a couple firmware updates released, so decided to give that a shot. I upgraded both devices from v1.0.6 to v1.0.13, and now they're both not appearing as connected devices on my router.

The connection appears to be working fine (albeit with random stability issues still, it seems like) -- MoCa light is on and flashing, LAN is flashing, and the satellite reports its backhaul is via a wired connection and everything appears to be working as expected.. However my router is not reporting the WF-803Ms as connected, so I can't get their IP addresses in order to connect to the WebUI to check their status and see what's going on. Attempting to connect to their previous IPs is not working either. I've tried resetting them both by holding the reset button in for 15+ seconds, both while plugged in and unplugged. I've also tried doing a ping sweep and the devices are not showing up.

The only other thing connected via coax is my cable modem, an Arris SB8200 (DOCSIS 3.1). This has also always been on the same network, since before I added the MoCa devices, and I've had zero issues for the past couple years until now.

What's going on, or how can I address/resolve this?

Upgrading the firmware reset both the devices to have static IPs, this is why they were not showing up as connected on my network.

Once I connected to them directly and went to the WebUI using the default IP of 192.168.254.254, I was able to get them reconfigured and working again.

Thank you for posting this thread.

I had the same problem with my two WF-803M units. Both units were programmed to obtain an IP address using DHCP with my router programmed to assign fixed IP addresses based on the units' MAC addresses. I was able to upgrade the firmware to 1.0.13, reboot the units, and confirm the new firmware was installed. The firmware upgrade went fine and I was able to connect to the devices using the IP addresses programmed into the router.

A few weeks later, when I did a LAN scan, I noticed the 2 units were missing from the scan. The MoCA network was working fine - I just could not connect to either unit using the IP addresses assigned by the router. There was an intervening power hit, so I am wondering if a power-on boot-up caused the devices to revert to using the default fixed IP address.

After reading this thread, I was able to direct connect to the units and change the IP address configuration back to DHCP and reboot. Everything is working as before now with the upgraded firmware.

As I stated in the OP, I've already done this, on both devices. I'll try again.

As I mentioned in the post, the devices are no longer showing up as connected devices on my network after the firmware upgrade. I can't get their IP addresses, so I can't get to the WebUI in order to check or change any settings.

Please follow these steps to revert back to the previous firmware.

1, Press the reset button.

2, Power up the device.

3, Wait for more than 10s, release the reset button.

4, After the device boot up, the device should revert to the previous firmware.

First, SB8200 is a DOCSIS 3.1 modem, and the upper frequency is 1218MHz. It have overlap with MoCA 1125-1675MHz. Please try to change the MoCA adapter to D-band high mode. de-select ext-D and D-low band.
