Archer C9 v5 AP mode stops giving out DHCP addresses
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Archer C9, when setup as a AP, with an upstream router/ modem, stops wireless clients from receiving DHCP addresses from upstream DHCP server after a few hours.
Have tried to configure the AP as DHCP client and also with static IP address, but the problem persists. In the DHCP client mode, I can see the AP requesting DHCP address from upstream DHCP server every few seconds.

What is the model number of the upstream router/ modem?
How about other devices in the network, are they all working fine when connecting to the upstream router/ modem network directly? What if you disable the Wi-Fi on the ISP router, only leave the Wi-Fi broadcasting on the C9, will it help?
You are also suggested making the Archer C9 as the main router if that is possible, then confirm if it can connect stably. If that gives you a stable connection, then there might be some special setting on the upstream router/ modem that cut it off from the network, you can contact the router support to confirm.

The upstream router is Linksys EA8300 running OpenWRT. I have also tried this setup with the upstream router as Linksys WRT3200 running on dd-wrt. All wireless clients work fine with the upstream routers.
The issue is only with Archer C9 connecting to the upstream routers. Archer C9 cannot be made the upstream router as it does not have good bandwidth management and policy features that OpenWRT or dd-wrt provide and Tp-link does not allow open source firmware on Archer C9 v5. So I guess I am stuck with a dud.

Check this guide to manually configure it into AP mode again, and set a static IP address for it, ensure the static IP is in the same IP subnet of the Linksys:

Looks like you did not read my initial problem statement.
Have already tried setting up the Archer C9 with static address. Even that stops working after some time.
