Wifi not Working

[d.]

My WiFi connection fails so sometimes I have a connection but only for 2 minutes then no longer even though my other devices have a great connection. I have already resetet my connectivity settings and it still isnt working. My phone is a S21 5G.

Chech the wifi channel and if the automatic detecting point enabled is.

When you using the router in a dualband mode with 2,4&5ghz try only the 2,4ghz... After that it don't jump around the connectivity between both signals, these are almost the problems when it's turn off or go away in a few minutes.

And the other devices use exactly the same position, same WLAN standard, same direction of same number of antennas as your mobile?

There are so many relevant factors worth a trial for fair comparison. It may be sufficient to change position and direction of your mobile.

If you need your current position and orientation of your mobile and your other devices are closer to your WLAN access, then you may try to use the lower frequenzy band as it reaches longer distances. Adding another access point is another option, especially if the distance to the router is lange.
