WiFi connection unstable

[stijnb1234]

My dongle has some wifi connection issues. After a day or so, it loses connection and does not reconnect / takes a lot of time to reconnect. It just falls back to Access Point mode without checking if a connection can be made with the same settings again.

I'm not fully sure how to debug / check.

Hi Stijn,

Minimal rssi should be -70. At lower rssi you get an unstable wifi connection and packet losses. The red light should always be on. blinking red light will indicate a power issue = usb charger is needed
