i currently live in a shared house and have done for 8 months, had no issues with the wifi until a new guy moved in last month. now every time hes in the house i lose the connection. this doesnt happen when anybody else is in the house so i find it kinda strange and seriously annoyiny!! my phone and my fire stick both say i am connected to the wifi with a strong signal yet they both disconnect as soon as this guy walks through the door.
can anybody shed any light on this??
