On my previous question, someone suggested to me to install an app called Wi-fi Analytics. This app allowed me to view that there were 5 other routers hooked up the same channel my router used (11). This explained my constant connection issues when using my internet browser, Minecraft multiplayer, etc. So, I accessed my router and rerouted it to channel 3, because in my area channel 3 seemed clear of other routers.
Now, I'm on channel 3, but I'm going on Minecraft servers and I'm receiving much greater lag than previously. Noticeable large freezes on servers, other players move around sluggishly or teleport around me, etc. The whole reason I switched channels was to avoid issues in which I'm using my browser/minecraft, and my browser loads very slowly, or the multiplayer servers continually state 'pinging' without loading. Now, that issue seems resolved, but this is honestly worse than before.
Why is this happening?
