Why signal dies in some rooms
- Distance and walls — especially brick, metal siding, and concrete
- Router stuck in a corner, closet, or behind a TV where signal cannot spread
- Old single-router setups that were never meant to cover your whole building
- Interference from microwaves, baby monitors, or crowded neighbor Wi-Fi channels
- Too many devices on one weak access point
Fixes that work vs band-aids
- Moving the router higher and more central often helps one problem room—not a whole shop floor.
- Cheap repeaters can make things worse by cutting speed in half.
- A properly designed mesh or wired access-point system covers the building with one network name.
- Business networks should separate guest Wi-Fi from computers that hold sensitive data.
What I do on site
I walk the building, measure signal, note interference, and quote gear that fits your layout—not oversell you a box from the big-box store. You get a map of what goes where and passwords documented for your records. If you just want it fixed and do not care about the radio physics, that is fine too.
