Model : CPE210

Hardware Version : V2

Firmware Version : CPE210_2.0-up-ver2-1-6-P1[20170908-rel45234]

I have two CPE210, hardware version 2, one acting as AP and one as client. I have assigned them static IPs, 192.168.5.10 (AP) and 192.168.5.16 (client).

When I don't assign mgmt vlan I can connect to the two devices using a manually set static IP on my computer (192.168.5.3) and connecting the network cable from my computer to the LAN input on the PoE injector. The two devices keep having a good and stable connection.

I then remove the static IP from my computer setting it in DHCP mode and receive an IP adress from the DHCP server (with range = 192.168.100-199). As soon as I do that I can no longer connect to (nor ping) either of the CPE210s, even though they are on the same subnet as my computer. They keep having a stable connection as verified by plugging another computer into the client and receiving an IP adress within the DHCP range and is able to surf the internet.

I go back to static IP on my computer and connect to the AP to set management vlan to 5, which is the vlan my computer is on using an EdgeRouter X as the brain to provide the DHCP server (actually a bunch of DHCP servers with corresponding vlans). The important part is that the bits and bytes going in to the AP is a trunc of several vlans.

I can successfully set the mgmt vlan to 5, and is then able to connect to the AP using DHCP on my computer. Everything would be a happy party then, if it wasn't for the reason that the AP at that point start losing its connection to the client every 4-5 seconds. If I log in to the the AP I can see that the number of connected devices flashes between 0 and 1 for about 4-5 seconds in each state. If I log in to the client I can see that the timer keeping track of the connection to the AP never reach more than 4-6 seconds and is then reset to 0.

Maybe this is firmware related or there is something else I'm missing. I noticed in another thread ( http://forum.tp-link.com/showthread.php?104188-CPE210-510-new-firmware-2.1.11-released-today-(includes-KRACK-fix) ) that there is a new firmware for HW version 3, but that it also works on CPE210 V2. Maybe someone can confirm this again in this thread, or maybe see beyond the troubleshooting already performed by me :)
