@Hank21 hello
1. May I know what device you want to connect your CPE to?
>> CPE210 (US version)
2. What is the IP of your CPE and what is the IP of the gateway in your LAN?
>> IP:10.10.10.254/24
>> GW : 10.10.10.1/24
3. Can you send us a screenshot of the error message?
>> I'll send it to you ASAP.
But the issue is that sometimes the device doesn't save its configuration properly. And sometimes, when the configuration is saved then the management interface is unreachable...http:10.10.10.254 doesn't respond while the web server is up (using scan IP Scanner Pro app to verify). I have to reset the device then go back to the factory configuration.
4. If your client connects to the CPE's WiFi can it get an IP?
>> I use the wire cable to access the device to configure it not the WIFI.
5. This configuration guide may be helpful if you have not seen it before:
>> not at all cause I've already download and read all you guides. I'm a network engineer with 20y of background in WIFI and I've been using TP-link devices since 2014. I was previously using TL-WA7210N and TL-WA7510N
Another partner told us that they had the same issue while configuring the CPE201/510. They send them back to the provider for an exchange.
Do you have known issue with the configuration of these devices or connection stability issues ?
