So, recently I got a new router that has two bands one that does 500mb/s and another that goes longer range that's around 30mb/s when it was first installed my cable was connecting to the faster connection, although then my mom wanted to move stuff around so she unplugged and replugging in stuff (no cables weren't plugged back in) and now the cable is connecting to the slower connection. Meanwhile, with other devices like my phone, it will be able to connect to the faster connection.
Thanks.
