You'll need :
2 wired wifi cables
a cardboard box
How to build :
First, put the 1rst router into the box then stick it in
2ndly, get the 2nd router and stick it in
3rdly, with one of the wifi cables, plug one of them in LAN1 on one of the routers. this will be your connector.
4thly, on the router that has LAN1 been connected. Connect another WiFi cable to your LAN2 to LAN1 on your other router.
then turn on your device and put on a game. you must crouch or something similar then plug in the lag switch and now the lag switch will turn off your lags.
thanks for building
