ESP8266 can't get DHCP IP addres from Asus router

Hi,

I have a problem described below. Is there any solution?

#### Platform
- Hardware: ESP8266-12F
- Core Version: Any higher then 2.5.2
- Development Env: Arduino IDE
- Operating System: Windows 10

### Settings in IDE
- Module: Wemos D1 R2 & mini
- Flash Mode:
- Flash Size: 4MB no SPIFFS
- lwip Variant: v2 Lower Memory
- Reset Method:
- Flash Frequency:
- CPU Frequency: 80Mhz
- Upload Using: SERIAL
- Upload Speed: 912600

### Problem Description

I use Wemos D1 mini R2 with Arduino core for ESP8266. With any core version higher than 2.5.2 ESP can't get DHCP IP address from ASUS RT-AX86U router (although according to debug data it succesfully connects to wifi).

When I revert back to core 2.5.2 or 2.5.0 ESP sucessfully connects to Asus router and gets IP address. Is it known issue?

Regards
