I have issue with CPE510 right after I try to connect the LAN into my home network.

At first I try configure with CPE510 on real structure (CPE510 placed on my tower and attach with long CAT5 cable). By using LAN on PoE PSU I'm able to configure CPE510 in access point mode, change the static IP from default 192.168.0.254 to 10.10.10.249 which my network use. All have been done correctly, the access point is accessible and reboot the device couple times. But then I try to switch the LAN cable from my laptop to my network following this schema:

The only thing that change is the cable from my switch to PoE PSU. And suddenly the configuration on CPE510 is gone, I can't ping to CPE510 using configured IP address (10.10.10.249) or factory IP (192.168.0.254). When I look on my router, I can see the IP that I reserve (10.10.10.249) is bound with CPE510 LAN MAC address. When I switch back same as how I configure CP510 (the first picture), I can't access CP510 either by 10.10.10.249 or 192.168.0.254. The only way that I can access CP510 is by doing factory reset (press reset button for 8 seconds)

At this point I don't know where the problem is, if the cable that used by CPE510 then I shouldn't able to configure the access point at first time. If the switch or router, but I have devices attach on the switch/router and those devices work fine. And I'm sure the cable from switch to PoE PSU is fine because I have switch it with cable that I use to configure.
