On Call: Techie fixed Wi-Fi dead zone with a drill

Welcome to another edition of On Call, The Register's reader-contributed column celebrating the art of tech support. This week, we introduce you to Eddy, the sole IT professional for an assisted living company. Eddy shared his struggles with creating a stable Wi-Fi network, which was complicated by multiple resident-owned routers emitting signals throughout the building.

After thorough troubleshooting, Eddy managed to establish a stable connection everywhere except one hallway at the back of the building. Frustrated, he decided to take a break and address another issue a user was experiencing: random monitor cuts out when someone quickly closed an office door. Upon investigating, Eddy discovered a stand supporting the pair of monitors, with power and video cables crimped together in the same hole of the desk's surface. Moving the stand caused the power cords to crimp, leading to intermittent monitor and Wi-Fi issues.

Eddy drilled a new hole for the stand and replaced the power cables, a fix that unexpectedly restored the Wi-Fi around the desk as well. However, the Wi-Fi dead zone in the back hallway persisted. Eddy concluded his email to The Register, stating he would attempt to find the second source of interference by using a software-defined radio dongle and waving a Yagi antenna like a demented wizard.
