My CPE210 V2 has the latest firmware, I updated it yesterday. It is in repeater mode, placed outdoors about 150' directly in front of the router which is in a window. It shows three bars of wifi. My cottage is directly in front of the repeater, about 50' away. No trees or obstructions in the way. When I reset my router the repeater works great with both my phone and my smart TV for several hours and then suddenly it will disconnect from the devices and say unable to obtain IP address. The devices still recognize the network and the repeater still shows three bars; the devices in the main house connected to the router still work. If I reset the modem, the process continues. Please help! I am sure I am driving my mother mad having her constantly reset the modem.
