Why your Wi-Fi dies in one room (a Boston housing story)
Plaster walls, brick, and tall narrow floor plans make Greater Boston homes genuinely hostile to Wi-Fi. Here is what actually fixes it, and what does not.
It is probably the building
Much of the housing around Boston predates Wi-Fi by a century. Plaster and lath walls contain a wire mesh that behaves like a radio shield. Brick exterior walls and chimneys at the center of a house block signal outright. A triple-decker's tall, narrow footprint means the router in the front living room is three plaster walls and a chimney away from the back bedroom.
So no, it is not just you, and moving the laptop closer to the window is not a plan.
What usually does not fix it
- 1Cheap plug-in repeaters. They rebroadcast a weak signal, halving speed while advertising full bars. The bars lie.
- 2Turning it off and on again, forever. Rebooting clears a jam; it does not move a chimney.
- 3Paying for faster internet. If the bottleneck is signal between rooms, a faster plan delivers the same dead zone at a higher price.
What actually works
First, measurement. Signal and speed checked room by room shows exactly where coverage collapses, and that decides the fix.
Then, in rough order of preference: repositioning the router centrally and off the floor; a mesh system with units placed where measurements say, not where outlets are convenient; a wired access point for the genuinely shielded rooms; and an Ethernet cable for the one device where reliability matters most, like a work computer. Old coax runs in many Boston homes can also carry a network signal with MoCA adapters, which beats fishing new cable through plaster.
The renter's version
No drilling required for most of this. Router placement, mesh, and MoCA over existing coax are all landlord-friendly. A technician can usually get a rented triple-decker unit to full coverage without a single new hole.
