Accessing CPE510 web management page connected to Deco M9 or M5 LAN port
I have no problem accessing a CPE510 web management page when the LAN port of the POE adapter is connected directly to a computer via cable. Pinging the CPE510 from the computer also works fine connected like this. CPE510 IP uses static IP = 192.168.68.101, subnet mask 255.255.255.0.
However, when I connect the LAN port of the POE adapter directly to a LAN port on a Deco M9 or M5, I'm no longer able to ping the CPE510, or access the web management page, even though the CPE510 (192.168.68.101) and my computer (192.168.68.125) are on the same Deco subnet (192.168.68.x 255.255.255.0). I am also unable to ping the CPE510, or access the web management page, if I insert an Ethernet switch in between the CPE510 LAN port and the Deco M9 LAN port. The destination CPE510 (192.168.68.101) becomes unreachable in both of those scenarios.
I have the CPE510 IP address 192.168.68.101 configured for IP Address Reservation in the Deco app.
The web management page shows: Device Model: CPE510 v3.0
The label on the CPE510 device shows: Model CPE510(US) Ver: 3.8
Given the difference in versions (v3.0 vs 3.8), it is unclear to me if I updated the CPE510 with the correct firmware.
The web management page shows firmware version: 2.2.3 Build 20201028 Rel. 55220 (5553)
Am I using the correct firmware?
Any other ideas?
