Each time I try to move foward my Picar-4wd using my cell phone the wifi connection closes after few seconds. What can cause wifi to close ?
You can check your router WiFi band.
You can switch the bands and see how it works.
2.4 GHz Band: 2.4 GHz is a common Wi-Fi band that is widely used. It provides better coverage and penetration, but due to its commonness, there may be more sources of interference.
5 GHz Band: 5 GHz is a newer Wi-Fi band that offers higher data rates and less interference compared to the 2.4 GHz band. However, due to its higher frequency, the signal spreads over a shorter range and has less penetration.
