The fastest way to calm a jumpy home connection is to stop guessing and measure the few numbers that matter. When you know where latency spikes, where packets go missing, and where radio conditions sag, fixes become surgical instead of superstitious. You don’t need a lab or fancy gear. One laptop or phone, a quiet hour, and a short checklist will tell you which rooms are honest and which rooms are faking it. Start by proving what your line can really do over a wire. Then walk the house with the same device, record delay and loss next to the signal you see, and note where roaming or congestion adds stutters. With that map in hand, you’ll nudge one or two settings, move a node or two, and enjoy steady performance everywhere you actually live.
