problems with WiFi.setPhyMode

[onkelfunny]

Sketch 1:
void setup() {
    WiFi.disconnect(true);
    delay(2000);
    WiFi.begin("ABCD12345678", "12345678");
}

Sketch 2:
void setup() {
    WiFi.disconnect(true);
    delay(2000);
    WiFi.setPhyMode(WIFI_PHY_MODE_11B);
    WiFi.begin("ABCD12345678", "12345678");
}

The esp runs great with Sketch 1. After Flashing Sketch 2 i can't connect to the Router.
Because Sketch 2 not working i tried Sketch 1 and now this is not working.

After a complete Flash erase, Sketch 1 works without problems.

may the SDK stores the WIFI_PHY_MODE_11B setting,
does your router support WiFi mode B?

[onkelfunny]

the router don't support mode b.

i have tried to set mode g and mode n but without luck.

I think the idk stores the information... the question ist how i can reset the mode without full flash reset?

[Links2004]

the sdk docs not write over it, you can try set it to 0 or
ESP.eraseConfig(); this will delete all SDK config

I can't reproduce this with latest git and my router. Closing.
