TP-Link ER605 and connected Archer C2(access point)
Model: ER605 (TL-R605)
Hardware Version: V1
Firmware Version: v1.0 1.1.1 Build 20210723 Rel.64608
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.
In Archer C2 I tried as described in TP-Link tutorial - Case 1: LAN-> LAN
In Archer C6 I tried as described in TP-Link tutorial - Case 2: WAN-> LAN.
DHCP disabled. Without result.
It seems to me that this is something with the ER605 settings, because in the Archer C2 and C6 devices connected via LAN work without any problems. The problem only occurs with connecting devices via WiFi.
Anyone have any ideas what could be causing this? Or maybe someone has encountered a similar problem?
