So I have a Realtek 8812BU Wireless LAN 802.11ac USB nic and have recently bought this. After I thought my old one didn't work but it turns out I'm still getting latency problems every couple of minutes I get packet loss or high ping and it will go away within seconds to about 30 seconds I have tried everything but I'm not sure what to do my parents updated the router Firmware the same day it started acting up and having these problems my dad has tried giving my computer priority and other things and I have run tracers in cmd and pinged a lot and checked my CPU and nothing raises when the lag happens so I think it is the router we have a Netgear 5g wifi which is from Xfinity. I also know that the connection strength isn't very good as I think it is like 30% and my dad who usually knows everything about this can fix it I honestly have no clue what to do. P.S I don't have a wired ethernet cable but I think it works better because I have one For my Xbox one and it lags too when it is not connected wired and in the same way my computer does (drivers are updated also)
