My WiFi is decent where i am but my family uses most of the bandwidth, i have issues like lag during games, slow downloads, i even had like 2 Kilobit per second (yes i checked it) it took me an hour to download a 16 MB file. Any solutions? I can buy an AP but,i only have a Ethernet cable which is a meter long and i am like 20-30 meters away from my router, so will a AP,switch or repeater help? ( I have about 2 MB at best)
