I cannot correctly connect to my home router (Virgin), unless l switch Flight Mode on/off. When l change locations in my property, l have again to switch Flight Mode on/off. Only once this process has been completed can l achieve the ISP speeds (circa Download 250mbs and Upload 26mbs). l have a Samsung M31. I have tried all options such as; forgetting network, clearing cache, safe mode, powersaving off. Can you please help and give me suggestions to obtain good wifi connection at home. All other devices connect to wifi without problems.
