My Wi-fi is fine and I don't lose posts or anything. It's you
I live in an area where everyone has wifi, and because they are thick, set them up like idiots, so they interfere with everyone elses. Then because they get shit wifi, they buy extenders, hindering the situation even more, so they go all in on the mesh wank. Result, nobody can use wifi here.
Things improved briefly, when I swiped 13 Homehubs from work, and set them all on different channels, and had broadcasts constantly going. But soon returned to normal.
To give you some idea how bad it is on 2.4Ghz here, ping paket loss between laptop and the access point is around 1% during a normal prelockdown day, to around 60% over an hour in the evening, or all the time currently.
