mmehta1 , via OnePlus 6 , Nov 19, 2020 : Wifi link speed ( receive link speed and transmit link speed) is slow and fluctuating. Because of this wifi is very slow. So far, I have tried below things: 1. Reset network settings 2. Tried connecting to different wifi router 3.Wipe cache and full factory reset phone But none of them has worked for me. Also i have checked other devices are working fine with the same wifi router.
