Archer C2 - Access Point mode
Hi Guys!I have a TP-Link ER605 wired router plugged into a Dasan H665 device from ISP. DMZ is set on my ER605 router. Then TP-Link Archer C2 is connected to the router in Access Point mode (DHCP disable).
Dasan H665 -> TP-Link ER605 (router) -> TP-Link Archer C2 (access point)
On the ER605 router I added fixed IP reservation addresses for my devices (from a different range than the addresses assigned by DHCP, in the same subnet) + IP-MAC Binding. For about a week, everything worked without any problems, and for several days I have had a problem with the wireless network on the access point. Devices connected to the LAN connect without any problems, but there is a problem with connecting to the WiFi network with various devices. The network is visible, sometimes it is possible to connect for a few seconds and then disconnect. On one of the phones I noticed that the message "getting an IP address" was appearing for a long time. Once it was able to connect and it allocated an IP address on the phone that was reserved for another device, once it gave a strange IP: 169.254.151.19 - the internet did not work.
I tried restarting the routers, reconfiguring the access point, and increased the lease time to max - to no avail. Firmware is up to date. I also tried replacing the Archer C2 router with Archer C6 also in access point mode, and also with TP-Link Deco M4 and the problem is the same all the time, so I conclude that the problem lies with the main ER605 router.
Anyone have any ideas what could be causing this? Or maybe someone has encountered a similar problem?
