ESP8266 can't connect to ASUS Routers

8<------------------------ BUG REPORT -----------------------------------------

Expected behavior

ESP8266/WEMOS D1 should connect to the local WiFi network

Actual behavior

ESP8266/WEMOS D1 tries forever to connect but fails 99% of the time. Sometimes it gets lucky and gets an IP address.
It seems to be a known issue: esp8266/Arduino#8299

8<------------------------ END BUG REPORT -------------------------------------

8<------------------------ FEATURE REQUEST ------------------------------------

To fix the problem a line needs to be added to the WiFi module settings in esp8266weather-station-color.ino
Please see below for an example. I inserted the bold line below. In my case to line 140.

void connectWifi() {
if (WiFi.status() == WL_CONNECTED) return;
//Manual Wifi
Serial.printf("Connecting to WiFi %s/%s", WIFI_SSID.c_str(), WIFI_PASS.c_str());
WiFi.disconnect();
WiFi.mode(WIFI_STA);
WiFi.setPhyMode(WIFI_PHY_MODE_11G); // Fix for ASUS RT-AX86U RT-AC86 Routers
WiFi.hostname(WIFI_HOSTNAME);

Hi. By adding the line it connects to wifi, but only after being programmed.
If you cycle the power is unable to connect again, a new upload is needed.
Could anyone fix this please?
Many Thanks!!
