realme mobile phone wifi may be slow for the following reasons:
First of all, the signal is not good, if you are too far away from the router or there are too many obstacles around the router, it will affect the strength of the wifi signal.
The second problem may be router Settings, you need to check whether the bandwidth is occupied by other devices or the router has set a limit.
There may also be problems with the phone itself, such as abnormal system updates or network delays caused by applications, and the need to clear the cache, update the system software, and close the background applications. Please handle the problem according to different situations.
This is generally because of your network signal reason, and the phone has little to do with it, you can be near a place with better network signal.
